The connecting shaft 1 is mainly used to connect the grab plate body 2 and the fixed seat and the bearing 5. Its main function is to connect. The bearing 5 mainly plays a role of rotation. It is the main working part of this device. The service life of the device mainly depends on the quality of the bearing 5, so the selected bearing 5 must be a high-quality product. Two slots 6 are provided on the outer side of the connecting shaft 1, and the inner sides of the two slots 6 are provided with a gasket assembly 4. The gasket assembly 4 mainly plays the role of fixing the bearing 5.

[0031] Reference Figure 1 and Figure 3-Figure 4 As shown, specifically, the gasket assembly 4 includes a first gasket 401 and a second gasket 402, and the first gasket 401 and the second gasket 402 are both semi-circular ring structures. By setting the gasket assembly 4 as a spliced ​​structure, it is convenient to regularly replace and install the gasket assembly 4 in the card slot 6, and further improve the performance of the device.

[0032] Two positioning pins 405 are fixedly connected to the surface of the second gasket 402, and two positioning holes 404 are provided on the surface of the first gasket 401. The size of the positioning holes 404 matches the size of the positioning pins 405, and a truncated cone block 406 is fixedly connected to the end side of the positioning pin 405. The truncated cone block 406 with a truncated cone structure improves the efficiency of inserting the positioning pin 405 into the inner side of the positioning hole 404. A second annular groove 409 is provided on the side wall of the first gasket 401, and a first annular groove 407 is provided on the side wall of the second gasket 402. The cross-sections of the first annular groove 407 and the second annular groove 409 are both isosceles trapezoids, and a swivel 403 with a semicircular ring structure is rotatably connected to the inner side of the second annular groove 409. The swivel 403 is passed through the inner side of the first annular groove 407, thereby realizing the snap assembly work of the first gasket 401 and the second gasket 402. Both ends of the swivel 403 are fixedly connected with positioning heads 410, which are terrace-shaped structures. The end sides of the swivel 403 are evenly fixedly connected with a plurality of anti-skid protrusions 411. By providing the positioning heads 410 with terrace-shaped structures, the efficiency of inserting the swivel 403 into the inner side of the first annular groove 407 is improved, and the provision of the anti-skid protrusions 411 facilitates the twisting work of the swivel 403. A plurality of rubber protrusions 408 are evenly glued to the inner side of the first annular groove 407.
