Specifically, the arc plate 230 is fixedly connected with the housing 210, and one end of the limiting bar 220 is also fixedly connected with the arc plate 230. The arc plates 230 are in the same shape as the embedded grooves 120, and after the six arc plates 230 are respectively embedded into the six embedded grooves 120, the axial limit of the nesting 200 can be realized. The axial limiting is that after the arc-shaped plate 230 is installed in the embedded groove 120, the arc-shaped plate 230 abuts against the bottom of the embedded groove 120, and the limiting strip 220 cannot continuously slide along the limiting groove 110, so that the axial limiting of the embedded sleeve 200 is realized.

It should be understood that the second screw hole 231 of the arc plate 230 is a stepped hole, the small bore section of the second screw hole 231 is only for the threaded shaft of the bolt to pass through, and the large bore end can allow the head of the bolt to enter. After the bolt is screwed into the first screw hole 121, the head of the bolt finally contacts with the stepped surface in the second screw hole 231. The second screw hole 231 is provided as a stepped hole in order to hide the head of the bolt into the arc plate 230, so that the end surface of the entire nest 200 is a flat surface and does not cause movement interference with other devices.

In some embodiments of the present invention, the end of the limiting groove 110 away from the embedding groove 120 is provided with a port groove 111, and the port groove 111 is communicated with the limiting groove 110; the limiting clamping piece 300 is installed in the port groove 111, two ends of the limiting clamping piece 300 are respectively embedded into the limiting groove 110 and the port groove 111, and the limiting clamping piece 300 is used for connecting the limiting strip 220 and the roller rod 100.

In some embodiments of the present invention, the limit clip 300 includes an upper end 310 and a lower end 320, the upper end 310 is partially inserted into the limit groove 110 and is bolted to the limit bar 220, and the lower end 320 is inserted into the insertion groove 120 and is bolted to the roller bar 100. Specifically, as shown in fig. 2, the length of the stopper bar 220 in the axial direction is smaller than the length of the stopper groove 110 in the axial direction, and the length of the upper end portion 310 in the axial direction of the roller bar 100 is greater than the length of the lower end portion 320 in the axial direction of the roller bar 100, so that the upper end portion 310 is partially fitted into the stopper groove 110. The partial embedding of the upper end portion 310 into the limiting groove 110 can reduce the mutual movement between the limiting strip 220 and the limiting clamping piece 300 when the nesting 200 moves relative to the roller rod 100, thereby reducing the abrasion to the bolt connecting the two.

In some embodiments of the present invention, the upper end portion 310 is provided with an upper screw hole 311 for passing a bolt, the lower end portion 320 is provided with a lower screw hole 321 for passing a bolt, and both the upper screw hole 311 and the lower screw hole 321 are stepped holes. Specifically, the limiting strip 220 is provided with a threaded hole corresponding to the upper threaded hole 311, and a threaded hole corresponding to the lower threaded hole 321 is also provided in the port groove 111. The stepped hole is provided to ensure that the bolt does not protrude beyond the surface of the limit clip 300.
