[0033] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0034] See also Figures 1 to 7 The adjustment structure 100 of the laser includes a telescope tube 1a1 and a laser module; the telescope tube 1a1 is provided with an eyepiece cavity, a prism cavity 1b and an objective cavity 1c which are connected in sequence along the axial direction, and the inner wall of the prism cavity 1b is provided with a mounting channel 1d which is connected to the outside; the laser module includes a laser 2 and an elastic member 3, the laser 2 is installed in the mounting channel 1d, and can move in the direction of approaching and moving away from the prism cavity 1b, so as to emit laser toward the prism cavity 1b, the elastic member 3 is connected to the laser 2 and the inner wall of the mounting channel 1d, and is used to provide an elastic restoring force to the sliding laser 2, so that the laser 2 can elastically move in the direction of approaching and moving away from the prism cavity 1b.

[0035] The utility model provides a laser adjustment structure 100, wherein the installation channel 1d is connected to the outside and the prism cavity 1b, and an elastic member 3 is provided between the laser 2 and the inner wall of the installation channel 1d, so that when the laser 2 is subjected to external pressure, the elastic force of the elastic member 3 can generate a floating support force away from the prism cavity 1b. The debugging personnel only need to press the laser 2 toward the prism cavity 1b until it reaches the same focal position, and no frequent disassembly and assembly are required, thereby improving the debugging efficiency and reducing the workload of the debugging personnel. At the same time, the structure is simple and the cost is saved.

[0036] For further information, see Figures 3 to 6, the inner wall of the installation channel 1d is convexly provided with a mounting platform 11, and the elastic member 3 is an elastic gasket 31, which is placed on the side of the mounting platform 11 away from the prism cavity 1b and can be deformed in the direction of approaching and moving away from the prism cavity 1b; the laser 2 is elastically pressed against the side of the elastic gasket 31 away from the mounting platform 11. In this embodiment, the elastic member 3 is set in the form of an elastic gasket 31, and the elastic gasket 31 can be compressed in the direction of approaching the prism cavity 1b when the laser 2 is pressed, thereby causing the laser 2 to move in the direction of approaching the prism cavity 1b until the laser 2 moves to the co-focus position; and the reaction force of the elastic gasket 31 can cause the laser 2 to be in a suspended state, which meets the debugging requirements, has a simple structure, and is easy to operate.

[0037] For further information, see Figure 4 , the elastic gasket 31 is arranged in a corrugated shape along its circumference. In this embodiment, the elastic gasket 31 is arranged in a corrugated shape along its circumference to improve the deformation ability of the elastic gasket 31 in the direction close to and away from the prism cavity 1b, thereby expanding the active stroke of the laser 2 and improving practicality. It should be understood that the crests and troughs of the elastic gasket 31 are arranged in sequence along the direction close to and away from the prism cavity 1b. In addition, in this scheme, the mounting platform 11 extends along the circumference of the mounting channel 1d and is arranged in a ring shape. In this way, the mounting platform 11 can better support the elastic gasket 31, so that the movement of the laser 2 is more stable. Specifically, in this embodiment, the mounting channel 1d extends along the radial direction of the telescope barrel 1a1, making the overall structure more compact, and can shorten the debugging stroke of the laser 2, further improving the debugging efficiency. It should be noted that in this scheme, an Abbe prism is placed in the prism cavity 1b.

In this embodiment, the detachable connection between the laser body 22 and the laser 2 is achieved through the matching of the fixing bolt, the matching hole 21b and the fixing screw hole 22a, and the structure is simple and reliable.

[0040] Specifically, a plurality of matching holes 21b are provided at intervals along the circumference of the connection channel 21a, and correspondingly, a plurality of fixing screw holes 22a and fixing bolts are provided, respectively, and each fixing bolt is sequentially inserted into the corresponding matching hole 21b and fixing screw hole 22a.
