Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The utility model provides the following technical solutions: Embodiment 1

[0025] Combination Figures 1 to 5 , a fixture with good fixing effect, comprising a support platform 1, a frame 2 is fixedly connected to the top of the support platform 1, a connecting mechanism 5 is arranged inside the support platform 1, an installation box 3 is arranged on one side of the connecting mechanism 5, and a clamping mechanism 4 is arranged inside the installation box 3;

[0026] The clamping mechanism 4 includes a motor 41, which is fixedly connected to the inner wall of the installation box 3. A worm 42 is fixedly connected to the output end of the motor 41. A worm wheel 43 is meshed with the outer wall of the worm 42. A threaded rod 44 is fixedly connected to the inner ring of the worm wheel 43.

A clamping plate 47 is fixedly connected to the top of the fixed block 46.

[0027] Furthermore, the threads of the outer walls at both ends of the threaded rod 44 are in opposite directions, and the two ends of the threaded rod 44 are rotatably connected to the left and right sides of the inner wall of the installation box 3 respectively, so that the rotational motion of the threaded rod 44 can be converted into the linear motion of the two moving blocks 45.

[0028] Furthermore, a through hole is provided inside the moving block 45 , and the moving block 45 is slidably connected to the outer wall of the slide groove 48 through the through hole, which can limit the moving block 45 during its movement.

[0029] Furthermore, a rectangular opening matching the fixed block 46 is opened on the top of the installation box 3 , and the fixed block 46 passes through the top of the support platform 1 through the opened rectangular opening, so that the moving block 45 can drive the clamping plate 47 to move through the fixed block 46 . Embodiment 2

[0030] See also Figures 1 to 5 On the basis of the first embodiment, the connecting mechanism 5 further comprises a connecting groove 51, the connecting groove 51 is opened on the top of the support platform 1, a connecting block 53 is inserted into the connecting groove 51, a bolt 52 is arranged inside the connecting block 53, and a slot 54 is opened on the top of the support platform 1, so that the staff can disassemble and replace the installation box 3.

[0031] Furthermore, mounting holes matching the bolts 52 are provided inside the connection block 53 and the inner wall of the connection groove 51. The bolts 52 are threadedly connected to the inner walls of the mounting holes, and the bolts 52 can be twisted by the twist block to rotate.
