[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

The limit shaft 203 is inserted into the limit groove 201 through the positioning hole of the limit plate 202 and the threaded rod 303 is rotated. It can be seen that the fixture body 1 is fixed on the reserved plate 101, and the reserved plate 10 1 is provided with a plurality of slide grooves 204, and the inner wall of the positioning hole 102 near the slide groove 204 is provided with a plurality of second slide grooves 205.

When the pull rod 207 is pulled outward, the fixed plate 209 is driven to move so that the fixed plate 209 squeezes a plurality of springs 211. At the same time, the pull rod 207 pulls the fixed block 208 outward in the process of being pulled outward.

The inner wall of the clamp body 1 is provided with a positioning mechanism 3, and the spring 211 can exert a certain elastic force on the fixed plate 209, thereby enhancing the pressure of the fixed block 208 against the limit plate 206 and preventing the limit plate 206 from falling off from the fixed block 208 by itself.

[0033] The plurality of limit plates 206 on the clamp body 1 are inserted into the slide groove 204 after passing through the reserved plate 101. During the insertion process, the limit plates 206 will press against the fixed block 208 to make it move outward. The outward movement of the fixed block 208 will drive the pull rod 207 to move outward so that the fixed plate 209 squeezes the plurality of springs 211. When the limit plates 206 are completely installed in the fixed block 208, the springs 211 will have elastic force to squeeze the fixed plate 209 to reset it, thereby making the fixed block 208 stuck on the limit plates 206, and fixing the clamp body 1 on the reserved plate 101.

Since the outer wall of the teeth 306 is meshed with the outer wall of the toothed slider 305, when the toothed slider 304 close to one end of the threaded rod 303 moves, the toothed slider 305 304 will be driven to rotate through the teeth 306, thereby causing the toothed slider 304 away from the end of the threaded rod 303 to move.

The threaded rod 303 can fix the position of the handle 309 to prevent the handle 309 from falling. At the same time, rotating the handle 309 can drive the threaded rod 303 to rotate so that the toothed slider 304 on the outer wall of the threaded rod 303 slides on the inner wall of the clamp body 1.

[0037] The movement of the toothed slider 304 will drive the toothed slider 2 305 to slide in the limiting slide groove 2 310, and the movement of the toothed slider 2 305 will drive the arc-shaped clamping plate 311 to move to fix the automobile caliper. By setting the arc-shaped clamping plate 2 312 and the arc-shaped clamping plate 3 313, the clamp body can always fit the outer wall of the automobile caliper, thereby enhancing the fixing effect.

After the clamp body 1 is fixed on the reserved plate 101, the limiting shaft 203 is inserted into the limiting slot 201 after passing through the limiting slot of the limiting plate 202 and rotating it half a circle, which can be further The fixing effect is enhanced to prevent the fixture body 1 from shaking during the subsequent processing. Then, the automobile caliper is placed between the elastic pads 314, and the handle 309 is turned. The rotation of the handle 309 will drive the threaded rod 303 to rotate, so that the toothed slider 304 close to one end of the threaded rod 303 slides on the fixture body 1. The sliding of the toothed slider 304 close to one end of the threaded rod 303 will drive the toothed slider 2 305 to make a circular motion around the toothed slider 304, so that the toothed slider 304 away from one end of the threaded rod 303 slides on the limit rod 302 at the same time and in the opposite direction. The movement will drive the second toothed slider 305 to move so that the arc clamping plate 311 moves simultaneously and in the opposite direction on the second limiting slide groove 310.
