The thirdrotating rod 333 comprises a fixedtube 4 connected with arotating part 335, a rotating slidingpart 5 telescopically and rotatably connected with the fixedtube 4, and a connecting part 6 connected with the clampingseat 32, the fixedtube 4 comprises apressure liquid cavity 41 for containing buffer liquid, the rotating slidingpart 5 comprises atelescopic rod 51 hermetically, slidably and rotatably connected with the fixedtube 4, and apiston 52 hermetically and rotatably abutted against the inner side wall of thepressure liquid cavity 41, one end of thetelescopic rod 51 extends into the fixedtube 4, the other end extends out and is fixedly connected with the connecting part 6, thepiston 52 can divide thepressure liquid cavity 41 into a front liquid cavity and a rear liquid cavity which are independently sealed, a first one-way valve 53 for allowing the buffer liquid in the front liquid cavity to flow to the rear liquid cavity and a second one-way valve 54 for allowing the buffer liquid in the rear liquid cavity to flow to the front liquid cavity are arranged on thepiston 52, and in the process of telescopic motion of thetelescopic rod 51 on the fixedtube 4, thefirst check valve 53 or thesecond check valve 54 is opened.

The flexible stretching and rotation between connecting portion 6 and fixedpipe 4 can be realized to the setting like this to utilize the hydraulic pressure principle of buffer solution can play the effect of automatic locking. Thepressure liquid cavity 41, thetelescopic rod 51 and thepiston 52 are matched to form a directional telescopic rotation locking structure, and as long as thetelescopic rod 51 is pulled, thepiston 52 on thetelescopic rod 51 is driven to move, so that the size of the space of the front liquid cavity and the space of the rear liquid cavity formed by thepiston 52 can be changed, and liquid in the space can flow to the enlarged space by extrusion, thereby realizing the telescopic effect; after the liquid in the front liquid cavity and the liquid in the rear liquid cavity are divided for the second time, the space of the new front liquid cavity and the space of the new rear liquid cavity can be kept unchanged under the action of no external force, and therefore locking is completed.

Connecting portion 6 is being close to or keeping away from fixedpipe 4's in-process, can also follow fixedpipe 4's axial rotation, thereby further enlargesupport 3 to the adjustment range ofgrip slipper 32 angle, position, thereby makechamber mirror 1's removal operation more convenient nimble, and preferablytelescopic link 51 all overlaps with the junction ofpiston 52 and fixedpipe 4 and is equipped with the sealing washer, be used for strengthening the gas tightness between the two, avoid the careless outflow of buffer solution in the fixedpipe 4 of removal in-process. The sealing ring not only can play the effect of reinforcing and sealing, but also can further strengthen the frictional force of thetelescopic rod 51, thepiston 52 and the fixedpipe 4, thereby realizing the rotation locking.

Thefirst check valve 53 and thesecond check valve 54 are embodied as follows:

thefirst check valve 53 comprises afirst channel 531 through which the liquid in the front liquid cavity flows into the rear liquid cavity, afirst ball plunger 532 arranged in thefirst channel 531 for blocking flow, afirst spring 533 connected with thefirst ball plunger 532, and afirst bolt 534 connected with the other end of thefirst spring 533, thetelescopic rod 51 is provided with a first through hole 511 for accommodating thefirst ball plunger 532, and thefirst bolt 534 is in threaded connection with the first through hole 511;

thesecond check valve 54 includes asecond channel 541 through which the liquid in the rear liquid chamber flows into the front liquid chamber, asecond ball plunger 542 arranged in thesecond channel 541 for blocking flow, asecond spring 543 connected with thesecond ball plunger 542, and asecond bolt 544 connected with the other end of thesecond spring 543, thetelescopic rod 51 is provided with a second through hole 512 for accommodating thesecond ball plunger 542, thesecond bolt 544 is in threaded connection with the second through hole 512, and the first through hole 511 and the second through hole 512 are respectively located at two opposite ends of thetelescopic rod 51.

First bolt 534 andsecond bolt 544 can constantly extrudefirst spring 533 andsecond spring 543 with the in-process oftelescopic link 51 spiral shell,first spring 533 andsecond spring 543 can make it be difficult to deformation because the space extrusion like this, thereby when opening or closingfirst passageway 531 andsecond passageway 541, need receive bigger external force and can change, can increase connecting portion 6 like this and feel through the retardant of the concertina movement ofrotation slide 5 on fixedpipe 4, thereby be difficult to lead to connecting portion 6 to remove to drive the skew ofgrip slipper 32 because of unexpected collision, also can further strengthen the fastness of locking betweenrotation slide 5 and the fixedpipe 4.

Because the second through hole 512 is disposed at the outward end of thetelescopic rod 51, if the buffer solution accidentally enters the second through hole 512 after the second one-way valve 54 is opened, the buffer solution will leak out along the opening of the second through hole 512, so that a sealing ring is disposed between thesecond bolt 544 and the second through hole 512 to enhance the sealing performance of the two, and the buffer solution is prevented from inadvertently flowing out of the second through hole 512 during the moving process. The first through hole 511 is provided at an inward end of thetelescopic rod 51, and if the buffer solution inadvertently enters the first through hole 511 after thefirst check valve 53 is opened, the buffer solution may enter the rear fluid chamber along with the extrusion, so that it is not necessary to further strengthen the sealing performance as thesecond bolt 544 does.

When connecting portion 6 need keep away from fixedpipe 4,telescopic link 51 is to being close to the removal of connecting portion 6 direction, drive the preceding sap cavity ofpiston 52 extrusion, liquid in the preceding sap cavity receives the space reduction of preceding sap cavity then begins to strike tofirst passageway 531, liquid is constantly receiving the in-process of lasting extrusion force, promotefirst ball stopper 532 to move to the one end that first through-hole leaned on the back, namelyfirst ball stopper 532 moves to back sap cavity direction,first spring 533 receives the extrusion shrink this moment, thereby openfirst passageway 531, liquid in the preceding sap cavity just can flow in back sap cavity, when external force withdraws, liquid in two cavities tends to steadily,first spring 533 resumes to natural state,first ball stopper 532 blocks upfirst passageway 531 again, therebytelescopic link 51 and fixedpipe 4's locking has been realized. When the connection portion 6 needs to be close to the fixedpipe 4, the direction is merely reversed as above.

The connecting portion 6 is made of a flexible material. The flexible material is free to flex, allowing the user to further adjustholder 32 to the appropriate angle and position.
