Detailed Description

The invention will be further described with reference to the accompanying drawings in which:

example (b): as shown in fig. 1 and 2, theright holder 2 slides on theleft holder 1 to form a pump holder clamping body, the self-locking nut 3, thelocking handle 4, thehorizontal cam 5, thevertical cam 6 and the stud 7 form an adjusting locking mechanism, thehorizontal cam 5 and thevertical cam 6 form a vertical cam structure, thehorizontal cam 5 and theright holder 2 form a horizontal cam structure, the self-locking nut 3 and the stud 7 control the overall height of thehorizontal cam 5 and thevertical cam 6, theright holder 2 and the adjusting locking mechanism are connected into a whole by the connectinglimiter 8, theright holder 2 can slightly move in the horizontal direction through the U-shaped hole in the connectinglimiter 8, and the groove in the bottom of thehorizontal cam 5 is matched with the connectinglimiter 8 to limit the locking mechanism within a 90-degree rotation range.

When the pump clamping seat is in a state shown in fig. 3, the pump clamping seat is in an unlocking state, thelocking handle 4 is pulled to adjust the opening so that an infusion rod can enter, then thelocking handle 4 is pushed, thelocking handle 4 drives the locking mechanism and theright clamping seat 2 to move together to be close to the infusion rod, after theright clamping seat 2 contacts the infusion rod, thelocking handle 4 is rotated, thelocking handle 4 drives thevertical cam 6 to rotate, when thevertical cam 6 rotates, the cam on thevertical cam 6 rises, the stud 7 is stretched, the pressure in the vertical direction is increased, the friction in the horizontal direction is increased, the locking mechanism and theright clamping seat 2 are prevented from retreating, meanwhile, the friction between thehorizontal cam 5 and the inclined surface of thecam 6 is increased, thehorizontal cam 5 is driven to rotate, when thehorizontal cam 5 rotates, thehorizontal cam 5 pushes theright clamping seat 2 to. When thelocking handle 4 rotates by 70 degrees, thehorizontal cam 5 reaches the highest point, then the locking handle enters into the equal-radius rotation, thevertical cam 6 continuously rises to increase the pressure in the vertical direction during rotation, the friction force in the horizontal direction is increased, the locking is further realized, and the retreating and loosening are prevented. At 90 degrees, the connectinglimiter 8 is limited to clamp thehorizontal cam 5 and cannot rotate, thevertical cam 6 is close to the dead point of thehorizontal cam 5, the whole adjusting and locking mechanism cannot rotate, the bayonet from thelocking handle 4 to theright clamping seat 2 is pressed, and thelocking handle 4 is prevented from being mistakenly bumped to cause loosening, and the adjusting and locking mechanism is particularly shown in fig. 4.

In addition to the above embodiments, the present invention may have other embodiments. All technical solutions formed by adopting equivalent substitutions or equivalent transformations fall within the protection scope of the claims of the present invention.
