[0009] According to the above technical solution, the surface of the tooth plate is set as slope one, the surface of the T-shaped plate is set as slope two, and the surface of the L-shaped plate is set as slope three, which reduces the safety hazards caused by tool slipping or misoperation.

[0010] According to the above technical scheme, the fixing device and the cleaning device are included, and the fixing device includes a fixing plate, a card plate, a slide plate, a telescopic clamp rod and a telescopic arc plate.

[0015] A method for using a measuring tool zeroing device, using the above-mentioned measuring tool zeroing device, comprising: Step 1: When the worker pushes the measuring tool toward the tooth plate, the measuring tool contacts and squeezes the tooth plate, and the tooth plate moves toward the direction close to the bidirectional threaded rod under the action of the measuring tool.

[0016] Step 2: The tooth plate moves to contact and drive the bidirectional threaded rod to rotate. At the same time, the rotation of the bidirectional threaded rod drives the clamping plate 1 and the clamping plate 2 to move towards the measuring tool until the measuring tool is clamped.

[0017] Step 3: When the second clamping plate moves upward, it drives the T-shaped plate upward, and the T-shaped plate moves upward to contact and squeeze the L-shaped plate.

[0018] Step 4: The L-shaped plate moves towards the measuring tool under the action of the T-shaped plate, and the movement of the L-shaped plate pushes the sliding plate to move until the measuring tool is clamped.

[0019] The present invention provides a measuring tool zeroing device and method, which has the following beneficial effects: (1) The measuring tool zeroing device pushes the measuring tool to be measured toward the tooth plate, and the measuring tool contacts and squeezes the tooth plate. The rotation of the bidirectional threaded rod drives the first and second clamps to move toward the measuring tool until the measuring tool is clamped. This ensures the stability and position consistency of the measuring tool during measurement, reduces the error caused by manual adjustment by the operator, and the adaptive clamping can improve the accuracy of the measurement result. At the same time, the L-shaped plate moves toward the measuring tool under the action of the T-shaped plate. The movement of the L-shaped plate pushes the sliding plate to move until the measuring tool is clamped, further improving the clamping effect. Clamping the measuring tool can prevent the measuring tool from accidentally moving during the measurement process, reducing the safety hazards caused by tool slippage or misoperation.

[0020] (2) In the measuring tool zeroing device, when the T-shaped plate moves upward, it drives the fixed plate to move upward. At the same time, the movement of the fixed plate drives the sliding plate to move upward. When the sliding plate moves, it drives the telescopic clamp rod to move upward. The telescopic clamp rod moves upward and then loses the restriction of the fixed platform. The free end of the telescopic clamp rod recovers and moves in the direction close to the measuring tool until the measuring tool is fixed tightly. This prevents the measuring tool claw from accidentally moving during the measurement process and affecting the adjustment accuracy. At the same time, the telescopic arc plate adaptively clamps the measuring claw of the measuring tool under the action of the measuring tool. Then the staff performs the next step of debugging, making the zeroing process simpler and faster, reducing the operator's adjustment time for the measuring tool position, thereby improving efficiency. The adaptive fixation reduces the operator's intervention and reduces the error caused by manual operation, thereby improving the reliability of the measurement result.

[0021] (3) The measuring tool zeroing device, when the clamp moves downward, drives the trigger plate to move, the trigger plate moves to release and squeeze the button, and the button is turned on at the same time, then the blower sprays air through the air pipe to the measuring tool, and the adjusting hole and surface of the measuring tool are cleaned by the gas, effectively removing dust, oil and other impurities on the surface of the measuring tool, ensuring that the measuring tool remains clean during measurement, thereby improving the accuracy of correction, the movement of the bevel plate drives the gear to rotate, the rotation of the gear drives the rotation of the shaft, and the rotation of the shaft drives the air pipe to rotate, realizing multi-angle jet cleaning, which can further shorten the cleaning time and reduce the workload of manual cleaning, thereby improving work efficiency.
