[0029] The working principle of the utility model is:

[0030] When in use, after gluing a connecting plate at the bottom of the brake pad, the brake pad is placed into the inside of the placement groove 21, and the connecting plate needs to be placed into the inside of the slot. When the connecting plate is placed into the inside of the slot, the screw fixedly installed at the bottom of the connecting plate will pass through the mounting seat 13 through the perforation. At this time, the nut is screwed on the outside of the screw to complete the installation and fixation of the brake pad. The spring 17 is initially in a compressed state. Rotating the mounting rod drives the observation plate 15 on its outside to rotate until the observation plate 15 is located above one of the brake pads. At this time, the nut 18 is turned to drive the observation plate 15 to slide on the outside of the mounting rod 1 and compress the spring 17 until the bottom of the observation plate 15 is in contact with the brake pad. After reading the scale at this time, the observation plate 15 is turned away from the top of the mounting seat 13. After the installation is completed, the second protective cover 12 is pushed until the limit pin 23 set on one side of the second protective cover 12 moves to the socket 24 and is inserted into it. At this time, the second protective cover 12 is completely covered in the detection The outer side of the component, and the metal plate 9 just moves to the position where it fits with one of the brake pads, close the closing door 14, start the motor 7, and the motor 7 drives the first bevel gear 3 and the second bevel gear 5 to engage and rotate. The first bevel gear 3 will drive the first rotating rod 4 to rotate and rotate the mounting seat 13. The mounting seat 13 drives the brake pad installed therein to rotate and rub against the metal plate 9. The second protective cover 12 prevents sparks from flying, and the first protective cover 10 prevents sparks from damaging the electric push rod 11. After the detection is completed, the second protective cover 12 is opened and the nut 18 is loosened. After the nut 18 is loosened, the spring 18 resets and drives the observation plate 15 to rise. The mounting rod 1 is rotated to make the observation plate 15 move above the brake pad. At this time, the previous operation is repeated to make the bottom of the observation plate 15 fit the brake pad. The reading at this time is read, and the specific value of the thickness difference of different brake pads within the same detection time can be obtained by subtracting it from the previous value.
