[0050] The scale 3 further includes: a digital display mechanism 6 slidably sleeved on the surface of the scale 3, and an adjustment frame 7 installed on the side of the digital display mechanism 6 and used to measure the workpiece.

[0051] The knob 5 includes: a screw rod 51 screwed into the shaft sleeve 8; a screw cap 52 integrally arranged at the end of the screw rod 51 penetrating the clamping pad 4 and located at the end of the shaft sleeve 8; a limiting groove 11 opened on the inner wall of the clamping pad 4 and slidably sleeved on the rib 12 integrally arranged on the shaft sleeve 8, and the rotary cap 52 is moved toward the shaft sleeve 8 by utilizing the rotation ability of the knob 5, thereby pressing the clamping pad 4 against the surface of the angle adjustment seat 2, and fixing the angle adjustment seat 2 by utilizing the tightening friction force;

[0052] Among them, the rib 12 is located on one end of the sleeve 8 that passes through the angle adjustment seat 2, and the rib 12 is completely located inside the clamping pad 4. The rib 12 is used to limit the sliding position of the clamping pad 4, so that the clamping pad 4 can only rotate with the rotation of the sleeve 8.

[0062] Working principle: when measuring a workpiece, first place the entire device on the platform where the workpiece is located. According to the inclination of the workpiece measuring surface, loosen the knob 5, swing the angle of the scale 3, and observe the adjustment of the scale 3 through the angle ruler 9 and the pointer 10.
