The mounting seat 9 is conveniently fixed and installed through the positioning holes 16 with bolts, thereby facilitating the installation and fixing of the entire roller ring pin on the counterpart.

[0029] Please refer to the attached figure in the instruction manual Figure 1 , Figure 4 and Figure 5 The top and bottom of the inner cavity of the mounting seat 9 are respectively provided with a second bearing 11 and a first bearing 7, and the first bearing 7 and the second bearing 11 are symmetrically distributed about the horizontal center line of the mounting seat 9. The arrangement of the first bearing 7 and the second bearing 11 facilitates the synchronous rotation of the first support seat 2 and the second support seat 14, and realizes the transmission of lines in different directions and angles.

[0030] Please refer to the attached figure in the instruction manual Figure 1 , Figure 4 and Figure 5 , the second bearing 11 and the first bearing 7 are respectively sleeved on the outer wall of the cylinder 4, the top of the cylinder 4 passes through the mounting seat 9 and is sleeved with the second support seat 14, a plane thrust needle roller bearing 8 is arranged between the top of the first support seat 2 and the bottom of the mounting seat 9, and a second gasket 10 is arranged between the top of the mounting seat 9 and the bottom of the second support seat 14. The arrangement of the plane thrust needle roller bearing 8 can reduce the friction between the first support seat 2 and the mounting seat 9 when rotating, and the arrangement of the second gasket 10 can reduce the friction between the second support seat 14 and the mounting seat 9 when rotating, thereby better protecting the first support seat 2 and the second support seat 14.

[0031] Please refer to the attached figure in the instruction manual Figure 1 , Figure 2 and Figure 3 A reserved hole 13 is provided at the center of the second support seat 14, and the second guide wheel 12 and the second guide wheel 15 are rotatably connected between the second support seats 14, the first wire wheel 1 and the first guide wheel 3 are arranged in parallel, and the second guide wheel 12 and the second guide wheel 15 are arranged in parallel.
