The jitter is a jitter in which the number of times the high level is generated by the micro switch 8 within a set time is larger than a set value.
The device also comprises a switch pressing depth judging module, wherein a distance sensor is arranged on the microswitch 8, the pressed depth of the microswitch 8 is judged and detected according to the detection value of the distance sensor, and if the pressed depth is smaller than a first set value, the laser transmitter 2 does not work; if the depth is larger than or equal to the first set value, the laser transmitter 2 works.
