[0033] By arranging the limiting fixed frame 7, the brake rubber block 5 can be installed and installed, and since the brake rubber block 5 is prone to wear, the brake rubber block 5 can be conveniently replaced.
[0034] It should be noted that the side surface of the positioning plate 201 is provided with two rectangular mounting holes, the inner wall of the rectangular mounting hole is rotatably connected with a guide roller 205 through a rotating shaft, the lower surface of the track shell 1 is provided with a strip-shaped guide hole, the left and right inner walls of the strip-shaped guide hole are both fixedly connected with guide strip blocks 6, the guide roller 205 is located between the two guide strip blocks 6, and the surface of the guide roller 205 is slidably connected with the guide strip blocks 6.
[0035] By setting the guide rollers 205, the guide rollers 205 can be used to slide between the two guide blocks 6, thereby improving the smoothness of the movement of the pulley mechanism 2 inside the track shell 1.
[0036] The buffer mechanism 3 comprises a U-shaped fixed plate 301 fixed at the end of the fixed frame 202, the surface of the U-shaped fixed plate 301 is provided with two limiting through holes, the inner walls of the two limiting through holes are slidably provided with two movable rods 302, one end of each of the two movable rods 302 is fixedly connected with a buffer push plate 303, the inner surface of the fixed frame 202 is fixedly connected with a mounting plate 304, and the surface of the mounting plate 304 is fixedly installed with a damping telescopic rod 305.

[0038] It should be noted that by providing the buffer mechanism 3 at the front and rear ends of the pulley mechanism 2, when the pulley mechanism 2 moves to the surface of the limiting cover 4 at one end inside the track shell 1, the buffer push plate 303 at the end of the U-shaped fixed plate 301 collides with the brake rubber block 5 on the surface of the limiting cover 4, thereby causing the buffer push plate 303 to move the movable rod 302, and in turn causing the linkage plate 306 to move towards the inside of the fixed frame 202, and at the same time, the linkage plate 306 pushes the damping telescopic rod 305, causing the damping telescopic rod 305 to contract, thereby buffering the impact force received by the buffer push plate 303 using the damping telescopic rod 305, achieving the effect of shock absorption, thereby avoiding deformation and damage of the front and rear ends of the pulley mechanism 2 due to collision, and helping to improve the service life of the pulley mechanism 2.
