A limiting hole 16 with a circular hole structure is opened on the mounting plate 3, and the limiting hole 16 corresponds to the position of the electric cylinder 2, and the limiting hole 16 is movably plugged with the piston rod 7. This structure enables the piston rod 7 to move up and down under the limit of the limiting hole 16. When the piston rod 7 rises, it drives One end of the clamping movable part 9 rises, and the other end of the clamping movable part 9 drives the clamping movable part 9 to move through the connecting rod 8, so that the clamping movable part 9 rotates relative to the mounting plate 3, and the relative position of the brake block 10 and the track guide rail 14 is adjusted to realize the clamping brake braking operation.
