In the drawings, the size and relative sizes of layers and regions may be exaggerated for clarity.
Referring to fig. 1-5, the invention provides a high-precision cross laser module, which comprises a lens barrel 1 and a laser component 8 arranged in the lens barrel, wherein the lens barrel 1 is also provided with a first cylindrical mirror 4 and a second cylindrical mirror 9, the first cylindrical mirror 4 and the second cylindrical mirror 9 are arranged vertically, and a laser beam 801 emitted by the laser component 8 vertically impinges on the first cylindrical mirror 4 and the second cylindrical mirror 9 to generate two mutually perpendicular laser lines 5 and 6; the lens barrel 1 is further provided with a first adjustment mechanism for adjusting an angle between the first cylindrical mirror 4 and the laser beam 801, and a second adjustment mechanism for adjusting an angle between the first cylindrical mirror 4 and the second cylindrical mirror 9.
According to the laser module, laser beams are irradiated onto the first cylindrical mirror 4 and the second cylindrical mirror 9 to directly form cross-shaped laser lines, and the first cylindrical mirror and the second cylindrical mirror are respectively subjected to angle adjustment through the first adjusting mechanism and the second adjusting mechanism, so that the two laser lines are in a high-precision stable 90-degree state; meanwhile, the invention has simple and compact structure, reduces the volume and greatly saves the cost.

Because the first cylindrical mirror 4 is fixed in the corresponding mounting hole in the lens barrel 1, the size of the mounting hole has some errors in the manufacturing process, so that the vertical precision between the first cylindrical mirror 4 and the laser beam 801 cannot reach high precision.
Specifically, referring to fig. 1-3, the first adjusting mechanism includes two slots 101 symmetrically disposed on the outer sidewall of the lens barrel 1, where the slots 101 are disposed along the radial direction of the lens barrel 1, that is, the two slots 101 are parallel to the first cylindrical mirror 4; the slot 101 is located on the outer sidewall of the lens barrel 1 between the first cylindrical mirror 4 and the laser component 8, that is, the slot 101 is located on one side of the first cylindrical mirror 4 away from the light exit end, that is, one side of the first cylindrical mirror 4 is the light exit side, and the slot 101 is located on the outer sidewall of the lens barrel 1 on the other side opposite to the first cylindrical mirror 4, as shown in fig. 1.
A first adjusting screw 2 is arranged in each slot 101, the first adjusting screw 2 is connected with the lens barrels at two sides of the slot, and the first adjusting screw 2 is arranged in parallel to the laser beam 801.

According to the invention, through the design of the contact surface between the protrusion and the lower concave part, the protrusion can be universally adjusted relative to the lower concave part; when the adjustment is needed, the second adjusting screw 3 is unscrewed, so that the protrusion can rotate and be finely adjusted in the lower concave part, the cylindrical lens base 7 can be finely adjusted relative to the lens barrel 1, the fine adjustment on the second cylindrical lens 9 can be realized, the high-precision verticality between the second cylindrical lens 9 and the first cylindrical lens 4 can be ensured, the high-precision verticality between the laser ray 5 emitted by the first cylindrical lens 4 and the laser ray 9 emitted by the second cylindrical lens 9 can be ensured, and two high-precision cross lasers with the precision within the range of 100 seconds can be formed.
