When the numerical control index plate body 1 is stopped, the staff rotates the two rotating blocks 5 in sequence clockwise, which can drive the locking screws 4 to rotate clockwise continuously and approach the positioning blocks 6, so that the locking screws 4 penetrate through the locking holes 7, thereby locking the disc brake 2 to avoid rotation caused by external force. At the same time, the external buffering structure composed of the sleeve 8, the damping spring 9, the piston rod 10 and the protective plate 11 plays a role of external elastic protection of the disc brake 2, thereby effectively improving the service life of the disc brake mechanism. When the disc brake 2 is subjected to external impact, the piston rod 10 and the damping spring 9 can absorb part of the impact force, thereby reducing the impact damage of the disc brake 2, and thereby effectively improving the service life of the disc brake mechanism.

[0024] It should be noted that the top of the protective plate 11 is bonded with a rubber pad 12, the shape of the protective plate 11 is arc-shaped, the outer diameter size of the locking screw 4 is smaller than the inner diameter size of the locking hole 7, and the locking screw 4 passes through the locking hole 7.

[0028] The working principle of the above embodiment is as follows:

[0029] When the numerical control index plate body 1 is stopped, the staff rotates the two rotating blocks 5 clockwise in sequence, so as to drive the locking screw 4 to rotate clockwise and approach the positioning block 6, and finally make the locking screw 4 penetrate through the locking hole 7, thereby locking the disc brake 2 to avoid external force from rotating. At the same time, the external buffer structure composed of the sleeve 8, the damping spring 9, the piston rod 10 and the protective plate 11 plays a role of external elastic protection of the disc brake 2, thereby effectively improving the service life of the disc brake mechanism.
