A scale rod 15 is fixedly installed between the two fixed plates 14. A measuring plate 17 is slidably installed on the outer wall of the scale rod 15 through a limiting mechanism. The limiting mechanism includes a measuring plate 17 fixedly installed on the two The limiting rod 16 is between the fixed plates 14, and the limiting rod 16 slides through the measuring plate 17. In the initial state, the inner wall of the measuring plate 17 is aligned with the zero scale of the scale rod 15. The limiting rod 16 can limit the measuring plate 17, so that the measuring plate 17 can only move axially along the outer wall of the scale rod 15. The inner wall of the measuring plate 17 is connected to the inner wall of one of the fixed plates 14 through a reset mechanism. The reset mechanism includes a reset spring 18 installed on the outer wall of the scale rod 15.
