[0028] Preferably, the mounting frame 3 includes a first fixing plate 31, a second fixing plate 32 and a mounting plate 33, wherein the first fixing plate 31 is arranged on the left side of the mounting plate 33, and the second fixing plate 32 is arranged on the right side of the mounting plate 33, and the first fixing plate 31, the second fixing plate 32 and the mounting plate 33 are matched and connected to jointly define a mounting cavity, one end of the pulley body 1 is rotatably set on the first fixing plate 31, and the other end is rotatably set on the second fixing plate 32, and the anti-collision plate 2 is located between the first fixing plate 31 and the pulley body 1 and / or between the second fixing plate 32 and the pulley body 1.

[0029] Specifically, it also includes a second connecting member 7, a fixing portion 35 is provided on the inner wall of the second fixing plate 32, and through holes are respectively opened on the first fixing plate 31, the anti-collision plate 2, and the pulley body 1. The second connecting member 7 passes through the through holes on the first fixing plate 31, the anti-collision plate 2, and the pulley body 1 in turn and is connected to the fixing portion 35.

[0030] Preferably, an anti-slip plate 6 is further included, and the anti-slip plate 6 is arranged on the outer side wall of the mounting frame 3.

[0031] Furthermore, it also includes a first connecting member 5 , a through hole 61 is opened on the anti-slip plate 6 , a connecting hole 34 is opened on the mounting frame 3 , and the first connecting member 5 passes through the through hole 61 and is connected to the connecting hole 34 .

[0032] In this embodiment, a first fixing plate 31 is provided on the left side of the mounting plate 33, and a second fixing plate 32 is provided on the right side thereof. The first fixing plate 31, the second fixing plate 32 and the mounting plate 33 are matched and connected to define a mounting cavity with an open lower end. One end of the pulley body 1 is connected to the first fixing plate 31 through an anti-collision plate 2, and the other end is connected to the second fixing plate 32 through another anti-collision plate 2, so that the pulley body 1 can be rotatably set in the mounting cavity, so that the sliding movement of the pulley body 1 can be protected by the two anti-collision plates 2, and the lower end of the pulley body 1 at least partially protrudes outward through the open end of the mounting cavity, so that a distance is formed between the lower end of the pulley body 1 and the lower end of the mounting cavity, thereby effectively protecting the sliding movement of the pulley body 1. More preferably, a fixing hole is provided on the inner wall of the second fixing plate 32 to form a fixing portion 35, and through holes are respectively opened on the first fixing plate 31, the anti-collision plate 2, and the pulley body 1.

More preferably, the distance between the lower end of the anti-slip plate 6 and the lower end of the mounting bracket 3 is greater than the distance between the lower end of the pulley body 1 and the lower end of the mounting bracket 3. Specifically, at least part of the lower end of the anti-slip plate 6 extends out of the bottom wall of the first fixing plate 31 and / or the second fixing plate 32, so that the lower end of the anti-slip plate 6 and the lower end of the mounting bracket 3 are At the same time, since at least part of the lower end of the pulley body 1 protrudes outward through the open end of the mounting cavity, at least part of the lower end of the pulley body 1 extends out of the mounting cavity, thereby forming a distance between the lower end of the pulley body 1 and the lower end of the mounting cavity. By making the distance between the lower end of the anti-slip plate 6 and the lower end of the mounting bracket 3 greater than the distance between the lower end of the pulley body 1 and the lower end of the mounting bracket 3, even if the height of the lower end of the anti-slip plate 6 is lower than the height of the lower end of the pulley body 1, the pulley body 1 can be better protected.

[0038] In this embodiment, in order to further protect the pulley body 1, a convex plate 4 is provided at the lower end of the anti-slip plate 6, and the convex plate 4 extends from the left and / or right side of the pulley body 1 toward its center at the end away from the anti-slip plate 6, that is, the convex plate 4 is provided on the first fixed plate 31, and the convex plate 4 extends from the first fixed plate 31 toward the second fixed plate 32, so that the convex plate 4 protects the lower end of the pulley body 1.
