The measuring component 3 includes a sensor 31 and a sensing head 32. The sensor 31 is telescopically sleeved in the first sleeve hole and extends out of the first sleeve hole; the sensing head 32 is connected to the bottom of the sensor 31, and one end of the sensing head 32 away from the sensor 31 is used to abut against the workpiece to be measured. Specifically, when measurement is required, the operator first places the workpiece to be measured on the measuring platform 101, and then a through hole is formed on the measuring platform 101. The operator starts the rotary clamping cylinder 2 to rotate and extend the extension shaft of the rotary clamping cylinder 2 through the through hole and clamp it with the bottom surface of the measuring platform 101. At this time, the sensing head 32 abuts against the workpiece to be measured on the measuring platform 101, and the sensing head 32 and the sensor 31 are displaced. The displacement generated by the sensing head 32 is transmitted to the sensor 31, and the sensor 31 processes the data to obtain the moving distance, thus completing the measurement.
