[0047] The use principle of the utility model is now described as follows:

[0048] Through the first handle 23, the support seat 2 is pulled out of the cabinet 1, and the compensation device body 3 is placed in the first concave cavity 21 and located between the clamping plates 51. The top ring 61 is pulled away from the gear 53 through the second handle 62. The top ring 61 is magnetically attracted to the metal block 222 through the magnet 64, and the top ring 61 is locked. The second hand wheel 54 is rotated to rotate the gear 53 and move the clamping plate 51 to the side of the compensation device body 3, and then the compensation device body 3 is calibrated to be in the middle position of the clamping plate 51. After the calibration is completed, the first hand wheel 42 is rotated to rotate the screw 41 and push the fixing block 43 to move in the direction of the compensation device body 3 until it abuts against the front of the compensation device body 3, so that the back of the compensation device body 3 is tightly attached to one end of the first concave cavity 21. This is to fix one side of the compensation device body 3, and then continue to rotate the second hand wheel 54 to make the clamping plates 51 tightly attached to both sides of the compensation device body 3, so that the compensation device body 3 is fixed;

[0049] In order to prevent the clamping plate 51 from moving backward, the second handle 62 is pushed to separate the magnet 64 from the metal block 222 , and the spring 63 releases elastic force to the top ring 61 , so that the top ring 61 is tightly attached to the gear 53 , thereby preventing the gear 53 from rotating.

[0050] The above design scheme can make the product have the advantages of wide adaptability, easy maintenance and convenient disassembly.

[0051] The above content is a further detailed description of the utility model in combination with specific implementation methods. It cannot be determined that the specific implementation of the utility model is limited to these descriptions.
