Since the card 414 is designed with a pointed end, it is convenient for the card 414 to be better inserted into the interior of the card seat 413. When the card 414 is inserted into the card seat 413, the fixing strip 2 402 and the fixing strip 1 401 corresponds to each other, and at the same time, the lock buckle 403 is inserted into the slot 405 opened in the fixing bar 1 401, so that the fixing bar 1 401 and the fixing bar 2 402 are closely fitted, and then the fastening bolt 411 is rotated to move, and the rotating disk 412 is driven to move by the fastening bolt 411, and the extrusion block 404 is squeezed by the rotating disk 412, and the connection plate 406 is set, and then the multiple groups of extrusion blocks 404 are driven to slide on the limiting plate 407 synchronously, and the slider 409 on the extrusion block 404 slides in the limiting groove opened in the limiting plate 407, so that the extrusion block 404 can be limited, so that the extrusion block 404 is more stable during the movement, and the extrusion block 404 is more stable. When the extrusion block 404 drives the slider 409 to move, the spring 1 408 is stretched. By setting the spring 1 408, when the extrusion block 404 is reset, the extrusion block 404 contacts the limit plate 407 to play a buffering effect. As the extrusion block 404 moves, the lock buckle 403 is squeezed, so that the fixing bar 1 401 and the fixing bar 2 402 can be closely fitted to each other to achieve a fixing effect. Through this operation, there is no need to screw multiple sets of screws, which improves the convenience of operation, saves time and effort, provides convenience for later maintenance, further improves the use effect of the device, and meets actual use needs. Then, the locking ring 501 on the protective cover 501 is 2 is inserted into the strip groove of the fixing strip 1 401, and the insert block 503 is pressed at this time to compress the spring 2 504, and then the protective cover 501 is pressed, and the spring 2 504 rebounds and drives the insert block 503 to be stuck into the inside of the locking ring 502, so that the protective cover 501 is installed and locked. Through the setting of the protective cover 501, the fastening bolt 411 and the limiting plate 407 can be protected to prevent dust and dirt from adhering to the surface of the fastening bolt 411 and affecting the meshing effect of the fastening bolt 411 and the fixing block 410, and at the same time, prevent dust and dirt from invading the limiting groove provided in the limiting plate 407 and affecting the sliding effect of the slider 409, thereby further improving the use effect of the device.
