The detection component 7 uses the slide rail 701 to help stabilize the overall direction of the detection component 7. After the clamping component 2 clamps the trapezoidal screw to be detected, the force sensor 702 is used to calculate the force input value, which helps the user obtain the input force data and facilitates subsequent calculations.
