A kind of quick coupling and instrumentTechnical field
The present invention relates to pipe joint technical field, especially a kind of quick coupling and instrument.
Background technology
People use garden instrument be engaged in mowing, prune, when cutting fruit, the saw work such as tree, frequently with extension pipe to expand workThe range of tool.But because extension pipe is longer, goods producer wishes that pipe can fold, stretch or fast quick-detach, in order toReduce the excessive packaging caused of Package size and cost of transportation；Additionally user also is intended to not take the biggest sky except instrumentBetween, also easy to carry.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiency in prior art, it is provided that a kind of quick couplingAnd instrument.
The technical solution adopted for the present invention to solve the technical problems is: a kind of quick coupling, is arranged on gardensBetween handle and the work head of instrument, including connecting tube, connecting tube tube wall is provided with a pair relative radial direction jack, in connecting tubeBeing inserted with extension pipe in hole, extension pipe tube wall is provided with a pair relative radial perforation, is fixed with keeper in extension pipe endoporus,Keeper is provided with radial direction through hole, and radial direction through hole is respectively arranged at two ends with movable latch, and movable latch includes being positioned at radial direction through holeBig footpath section and stretch into the path section in connecting tube radially jack by extension pipe radial perforation, path g. slice header is hemispherical,The spring offseted with both it is provided with between two movable latch.
A kind of instrument for described connecting tube being separated with extension pipe, including the U-shaped by elastic wire bendingPart, U-shaped part has a cross bar and two montants, and montant free end has the pin extended internally after bending.
In the middle part of described U-shaped part cross bar rolled after in the form of a ring.
The invention has the beneficial effects as follows, the simple in construction of the present invention, practicality, can sharp separation connecting tube and extension pipe.

Detailed description of the invention
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, only withThe basic structure of the illustration explanation present invention, therefore it only shows the composition relevant with the present invention.
A kind of quick coupling as shown in Figure 2, is arranged between the handle of garden instrument and work head, including evenAdapter 4, connecting tube 4 tube wall is provided with a pair relative radial direction jack 5, is inserted with extension pipe 6, extension pipe 6 in connecting tube 4 endoporusTube wall is provided with a pair relative radial perforation, is fixed with keeper 7 in extension pipe 6 endoporus, and keeper 7 is provided with radial direction through hole8, radial direction through hole 8 is respectively arranged at two ends with movable latch 9, and movable latch includes the big footpath section being positioned at radial direction through hole 8 and by addingLong tube 6 radial perforation stretches into the path section in connecting tube 4 radially jack 5, and path g. slice header is hemispherical, two movable latch 9 itBetween be provided with the spring 10 offseted with both.
A kind of instrument for described connecting tube 4 and extension pipe 6 being separated as shown in Figure 1, rolls over including by elastic wireCurved U-shaped part, U-shaped part has cross bar 1 and two montants 2, and montant 2 free end has the pin extended internally after bending3。
For ease of people's field work, rolled in the middle part of described U-shaped part cross bar 1 after in the form of a ring, in order to people are by this workTool hangs on and carries on key chain.
When separating connecting tube 4 with extension pipe 6, by the pin 3 of this instrument, the activity in connecting tube 4 radially jack 5 is insertedPin 9 path section heads in extension pipe 6 radial perforation, can extract extension pipe 6 out, thus reach both from connecting tube 4 endoporusThe purpose separated.
With the above-mentioned desirable embodiment according to the present invention for enlightenment, by above-mentioned description, relevant staff is completeEntirely can carry out various change and amendment in the range of without departing from this invention technological thought.The technology of this inventionThe content that property scope is not limited in description, it is necessary to determine its technical scope according to right.
