As a preferred embodiment, the four side walls of the piston block are all fit with the inner wall of the protective cylinder; the piston block can only lift vertically under the action of the spring, and can not shake in other directions.

As a preferred embodiment, four corners of the mounting plate are tapped with threaded holes; by installing bolts in the four threaded holes, the mounting plate can be fixed below a designated structure, so that the structure below the mounting plate can be kept stable.

As a preferable implementation scheme, the top end of the attaching rod is fixedly welded with a limiting plate; the limiting plate can be used for avoiding damage caused by direct impact between the attaching rod and the mounting plate.

A castor for a castor brake frame comprises side extension plates symmetrically welded on two sides of the bottom wall of a frame body and a roller wheel rotatably connected between the two side extension plates.

As a preferred embodiment, a plurality of tooth grooves are formed in the outer wall of the side extension plate, wherein the tooth grooves are distributed in a circumferential array along the central axis of the side extension plate, and the cutting plate is matched and spliced with the tooth grooves; therefore, the side extension plate can be limited by the cutting plate, and braking is realized.

In summary, the technical effects and advantages of the present utility model are:
