Furthermore, the two clamping pieces and the positioning holes in the middle of the clamping pieces are integrally formed, so that the error precision in processing is reduced, and the integral precision of a product is guaranteed.

Furthermore, the return spring is made of high-quality piano steel materials, so that the service life of the spring is prolonged.

The utility model has the advantages that:

the utility model discloses when using, through setting up cylinder body, first fixed pin, clamping piece, second fixed pin and answer the spring, here we will be original answer spring steel and change the selection into high-quality musical instrument steel material to propose for the first time at the spring both ends increased the spring protection pin, the effectual spring atress of having protected deformation can not certain warp too big in a department, effectively ensured spring life. Secondly, the aluminum alloy material of the original clamping piece positioning pin is changed into 304 stainless steel material, the diameter of the original clamping piece positioning pin is changed into 4mm, the smooth surface is changed into a straight grain structure, the clamping piece positioning pin can be closely connected with the cylinder body and is not easy to loosen, and finally the clamping piece of the clamp is changed into a clamping piece and positioning hole forming structure, so that the error precision in processing is reduced, and the integral precision of the product is ensured. Through the improvement, the service life of the clamp is improved qualitatively from 3-10 ten thousand times to more than 200 ten thousand times, the clamping pieces are firmly positioned and cannot fall off, the clamping pieces are integrally formed, the consistency of the mini clamp is guaranteed, the product is light in weight and small in size, and the action is flexible.

Detailed Description

As shown in fig. 1 and fig. 2, a mini fixture is related to, including

cylinder body

1, 1 one end of cylinder body is the design of U type opening, and cylinder body 1 keeps away from U type opening one side and is equipped with the air tap 2, cylinder body 1 has been close to U type opening one end both sides and has been seted up two

pinhole

3, 3 inside first fixed pins 4 that all are equipped with of two pinholes, the inside both sides of U type opening of cylinder body 1 all are equipped with two clamping pieces 5, the locating hole has all been seted up at two clamping pieces 5 middle parts, two clamping pieces 5 adjacent sides all are fixed with second fixed pin 6, and the common cover in second fixed pin 6 surface of two clamping pieces 5 has answer

spring

7, 1 both sides of cylinder body all are equipped with end cap 8, sliding tray 9 has been seted up at 1 middle part of cylinder body, and the inside slip of sliding tray 9 is equipped with two pistons 10, two pistons 10 surface covers are equipped with sealing washer 11.

As shown in fig. 3, the two clamping pieces 5 are sleeved on the surface of the first fixing pin 4 through the positioning holes and are rotatably connected with the first fixing pin 4.
