[0024] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0025] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0026] Embodiment 1, as Figure 1-Figure 4 As shown, the utility model provides a clamp for instrument assembly, comprising a clamping mechanism 1, a moving mechanism 2 is fixedly installed at the bottom of the clamping mechanism 1;

[0027] The clamping mechanism 1 includes four supporting legs 101, a supporting plate 102 is fixedly installed between the tops of the four supporting legs 101, a group of ear blocks 103 are fixedly installed on the top of the supporting plate 102, a group of first holes 104 are opened on the outer wall of the group of ear blocks 103, a bidirectional threaded rod 105 is movably inserted between the inner wall of the group of first holes 104, the outer wall of the bidirectional threaded rod 105 is rotatably connected to two threaded blocks 106, an adjusting wheel 107 is fixedly installed on one side of the outer wall of the bidirectional threaded rod 105, and the outer walls of the two threaded blocks 106 are rotatably connected to the outer wall of the two-way threaded rod 105. Five outer shells 108 are fixedly installed on one side of the wall, and a fixing plate 109 is fixedly installed on the bottom of the inner wall of the ten outer shells 108. A group of springs 110 is fixedly installed on the outer wall of the ten fixing plates 109. A moving block 111 is fixedly installed between the outer walls of the ten groups of springs 110. A group of extrusion blocks 112 are movably inserted into the inner wall of the ten outer shells 108, and the outer walls of the ten groups of extrusion blocks 112 are in contact with the outer walls of the moving blocks 111. A group of rubber heads 113 are fixedly installed on one side of the outer walls of the ten groups of extrusion blocks 112.

[0028] The effect achieved by the entire embodiment 1 is that the instrument is placed on the support plate 102, and then the adjusting wheel 107 is rotated to drive the two threaded blocks 106 to move closer to each other by driving the bidirectional threaded rod 105. At this time, a group of rubber heads 113 will be driven by the irregular surface of the instrument to drive a group of moving blocks 111 to slide into the inside of the housing 108. When a group of moving blocks 111 moves, it will squeeze an extrusion block 112. The positions of a group of moving blocks 111 and a group of rubber heads 113 are adjusted by moving the extrusion block 112. Multiple groups of rubber heads 113 cooperate with each other to clamp and fix the instrument. When the clamping is completed, a group of springs 110 will pull the moving block 111 to make a group of extrusion blocks 112 return to their original positions. Through the cooperation of multiple groups of rubber heads 113, instruments of different sizes and models can be fixed without using multiple clamps. It is not only convenient to use, but also cost-saving.

[0029] Embodiment 2, as Figure 2-Figure 4 As shown, the moving mechanism 2 includes four turntables 201, and a fixed shell 202 is fixedly installed on the bottom of the four turntables 201. The outer walls of the four fixed shells 202 are each provided with a group of second holes 203, and a rotating shaft 204 is fixedly inserted between the inner walls of the four groups of second holes 203. The outer walls of the four rotating shafts 204 are movably sleeved with rollers 205, and the bottoms of the four supporting legs 101 are fixedly connected to the top of the turntable 201.

[0030] The effect achieved by the entire embodiment 2 is that when the clamp needs to be moved, the four rollers 205 at the bottom can be rotated to drive the clamp forward, and the four turntables 201 can freely adjust the forward direction of the clamp, which not only facilitates the movement of the clamp, but also improves the adaptability of the clamp.

[0031] Working principle: When the instrument needs to be assembled, the clamp can be pushed first, and then the four fixed shells 202 at the bottom of the clamp can drive the four rollers 205 to rotate on the outer wall of the four rollers 205, driving the clamp forward. At the same time, the four turntables 201 can adjust the direction of the clamp's advancement. Then, the instrument is placed on the support plate 102, and the adjusting wheel 107 is turned. The adjusting wheel 107 will drive the bidirectional threaded rod 105 to rotate. When the bidirectional threaded rod 105 rotates, it will drive the two threaded blocks 106 to move closer to each other through the surface threads, so that Multiple groups of rubber heads 113 fixedly installed on one side of the outer wall contact the instrument. At this time, the multiple groups of rubber heads 113 will be driven by the instrument to slide into the multiple shells 108. When a group of rubber heads 113 moves, it will drive a group of moving blocks 111 to start moving together. A group of moving blocks 111 will squeeze the internal squeezing blocks 112, so that the squeezing blocks 112 start to pull a group of springs 110 to move inside the shell 108, so that the positions of a group of rubber heads 113 are different, and then the multiple groups of rubber heads 113 cooperate with each other to fix the position of the instrument.

[0032] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
