[0002] A laser line projector refers to a leveling instrument that guides a laser beam emitted by a laser device into a telescope barrel of the leveling instrument and allows the laser beam to be emitted along the direction of the collimation axis of the laser line projector; based on this, the laser line projector is usually provided with a transparent window through which the laser beam is emitted, so as to simultaneously meet the requirements of laser beam penetration and protection of the laser device.

[0003] For example, a 360-degree laser line projector convenient to use disclosed in the authorized announcement CN210533367U comprises a shell module and a core module installed inside the shell module; wherein the core module is provided with a laser device for emitting a laser beam, the shell module is provided with a transparent window for the laser beam to penetrate, and the transparent window is installed outside the shell module through bolts; when in use, the laser beam of the core module penetrates the transparent window of the shell module to realize the propagation of the laser path.

[0004] However, the transparent window of the existing laser line projector is installed outside the shell module through bolts, and when the inner surface of the transparent window needs to be cleaned or the laser device needs to be repaired and adjusted, the transparent window needs to be disassembled by means of a screwdriver tool first, which not only causes complicated steps, but also causes the transparent window to be difficult to install due to the bolt slipping after being disassembled and installed for many times.

The window mechanism 21 is tightly arranged inside the first sealing ring 31, and the bottom profile of the window mechanism 21 is larger than the top profile. After the window mechanism 21 is tightly arranged inside the first sealing ring 31, the fixing part 221 needs to be installed. The fixing part 221 is fixedly arranged at the top of the stepped groove 3 by embedding, and is tightly arranged outside the first sealing ring 31, thereby compressing and limiting the first sealing ring 31, achieving the purpose of limiting the first sealing ring 31 from separating from the stepped groove 3 of the laser pointer body 1. The supporting part 222 is provided with four groups. The four groups of supporting parts 222 are integrally formed at the bottom of the four corner positions of the fixing part 221, and are in abutment with the movable mechanism 23, thereby forming a fixed mechanism 22 with a hollow design, for supporting the window mechanism 21 to have light transmission conditions.

[0029] In the present embodiment, the window module 2 is configured with three groups, and the three groups of window modules 2 are arranged at the top and adjacent two sides of the outer periphery of the line-throwing instrument body 1. The angle between the plane formed by the side close to each other of any two groups of window modules 2 and the horizontal plane is 45 degrees.
