The top and side of the adjusting seat 1 are respectively provided with an adjusting mechanism 2, and the bottom of the adjusting mechanism 2 abuts against the outer side of the cylinder wall of the adjusting cylinder 3, and the adjusting mechanism 2 and the adjusting spring 6 can limit the movement of the adjusting cylinder 3 in the illustrated plane. The adjusting cylinder 3 is provided with a window glass 7 and a glass retaining ring 8 near the emitting end of the laser 4, the window glass 7 is fixed to the front end of the adjusting seat 1 by the glass retaining ring 8, and there is an annular groove on the outer side of the other end, and the adjusting spring 6 is disposed in the annular groove, and the other end of the adjusting spring 6 abuts against the spring washer 11 pressed by the spring retaining ring 10 fixed to the adjusting seat 1; there is a small groove on the outer side of the spherical surface of the adjusting cylinder 3, and the anti-rotation pin 9 mounted on the adjusting seat 1 is disposed in the groove.

[0024] The radial four directions of the adjusting cylinder 3 are restricted by the adjusting mechanism 2 and the adjusting spring 6; the axial directions of the adjusting cylinder 3 are respectively restricted by the adjusting seat 1 and the adjusting spring 6; the circumferential direction of the adjusting cylinder 3 is stuck by the anti-rotation pin 9 mounted on the adjusting seat 1 in the groove on its outer diameter to prevent the adjusting cylinder 3 from rotating along its circumferential direction.

[0025] The adjusting mechanism 2 includes an adjusting knob base 201, an adjusting knob 202, an adjusting nut 203 and an adjusting retaining ring 204; the adjusting knob 202 and the adjusting nut 203 are in threaded connection, the adjusting nut 203 is restricted in the circumferential direction by the adjusting retaining ring 204, and by rotating the adjusting knob 202, the adjusting nut 203 can move along its axial direction.
