[0025] Among them, the brake shoe 1 includes shoe one 101 and shoe two 102, the outer surface of shoe one 101 and shoe two 102 is provided with friction plate 103, the inner side of friction plate 103 is provided with mounting block 104;

[0026] The clamping assembly 2 includes connecting block 201, connecting block 201 is arranged on shoe one 101 and shoe two 102, the connecting block 201 is movably connected with movable block 202 inside, the movable block 202 is provided with clamping block 203 on the top, the clamping block 203 penetrates through the connecting block 201 and extends into the inner cavity of mounting block 104.

[0027] When the movable block 202 moves downward, the clamping block 203 is driven out of the inner cavity of the mounting block 104 by the movable block 202, the clamping of the mounting block 104 is released, and then the friction plate 103 is pulled out, the mounting block 104 is driven to move away from both sides of shoe one 101 and shoe two 102, the mounting position of the friction plate 103 is limited by the mounting block 104, preventing the position deviation of the subsequent replacement friction plate 103, so as to facilitate the operator to disassemble and install the damaged friction plate 103, reduce the use cost, and bring convenience to the use of personnel.

[0028] Embodiment 2

[0029] As Figures 3 to 5 shown, the embodiment contains the characteristics of embodiment 1, the difference is that shoe one 101 is connected with shoe two 102 by spring one 105, spring one 105 is provided with two, two spring one 105 are located on both sides of shoe one 101.

[0030] When shoe one 101 and shoe two 102 move outward, the spring one 105 is restored by the elastic force, driving shoe one 101 and shoe two 102 to merge, which is used to release the friction of the brake drum and complete the speed reduction of the vehicle.

[0031] Among them, the movable block 202 is provided with spring two 204 at the bottom, and the spring two 204 is connected with the inner wall of connecting block 201 at the bottom.

[0032] When the abutment of the movable block 202 is released, the movable block 202 will be subjected to downward pressure due to the stretching state of the spring two 204 at this time, which facilitates the downward movement of the movable block 202 and the clamping block 203, releases the clamping of the mounting block 104, so as to facilitate the operator to replace the seriously worn friction plate 103.
