The dial rod 52 is used for dialing the grooved wheel 4, the pattern disc 2 is provided with a plurality of light holes 21 distributed along the circumferential direction, and each light hole 21 is provided with a pattern light-transmitting piece (not shown). When the light beam irradiates the joint (refer to a position in fig. 1) between the two light holes 21, the moving block 51 just drives the light shielding sheet 3 to swing to the path of the light beam shielding the joint.
