[0023] Furthermore, the device for measuring the starting force of a disc brake further includes two first reinforcing rib blocks 21. Two adjacent sides of the first reinforcing rib blocks 21 are respectively fixed to the tappet support plate 12 and the base 11, and the two first reinforcing rib blocks 21 are respectively located on both sides of the tappet support plate 12.

[0024] Further, the device for measuring the starting force of the disc brake further includes a second reinforcing rib block 22. Two adjacent sides of the second reinforcing rib block 22 are respectively fixed to the base 11 and the connecting plate 13, and the second reinforcing rib block 22 is located on the side of the connecting plate 13 away from the tappet support plate 12.

[0025] Further, a groove 111 is provided on the base 11, and the connecting plate 13 is fixed in the groove 111.
