DETAILED DESCRIPTION

[0023] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0024] Embodiment 1

[0025] like Figure 1 As shown, in this embodiment, the marking instrument is provided with a shell 4 and a laser head 2. The lower half of the laser head 2 is arranged in the second arc-shaped mounting groove 13 of the mounting seat 8 of the shell 4, and the upper half is in contact with the wall of the first arc-shaped mounting groove 12 of the movable mounting block 10. The laser head 2 is a cylindrical structure, and an annular protrusion 6 concentric with its cylindrical structure is arranged on its outer circumference surface. The laser head 2 can swing up and down and left and right around the annular protrusion 6.

[0026] An adjustment hole 16 is also provided on the laser head 2. The adjustment hole 16 and the annular protrusion 6 are located in the same vertical plane. A through hole 24 is also provided on the movable mounting block 10. During adjustment, the adjustment rod of the rod-shaped structure is inserted into the adjustment hole 16 through the through hole 24, so that the annular protrusion 6 in the laser head 2 rotates in the first arc-shaped mounting groove 12 and the second arc-shaped mounting groove 13, thereby rotating the laser head 2 around the horizontal axis. Two adjustment holes 16 are provided, which are symmetrical around the vertical plane passing through the axis of the laser head 2, that is, the laser head 2 can be adjusted to rotate clockwise through one adjustment hole 16, and the laser head 2 can be adjusted to rotate counterclockwise through the other adjustment hole 16.
