The top baffle 3 can be used to form a closed space with the side baffle 2 through the setting of the top baffle 3, so as to shield and protect the grinding of the brake pads in the side baffle 2;

[0022] When adjusting and using, first set the brake pad limit on the upper surface of the connecting base 8, then drive the screw rod 5 to rotate and adjust through the servo motor, and then drive the lifting block 6 to drive the limit connecting ring 7 and the connecting base 8 to move downward by adjusting the rotating screw rod 5 thread, so that the limit connecting ring 7 drives the top baffle 3 to move downward through the two connecting rods 10, so that the top baffle 3 that moves downward is used to close the top of the side baffle 2, and a closed space is formed by the top baffle 3 and the side baffle 2 to block and protect the grinding of the brake pad on the upper surface of the connecting base 8;
