The lifting adjustment mechanism provided by the embodiment of the application is suitable for a laser light path 100, and can comprise a bottom plate 10, a first guide assembly 20, a lifting block 30, a driving block 40 and a driving assembly 50.

The base plate 10 is the mounting base for the drive block 40 and the drive assembly 50. The base plate 10 may have a plate shape with a flat upper end surface to facilitate translation of the drive block 40.

Referring to fig. 1, a first guide assembly 20 is provided to the base plate 10 in a height direction Z to guide the lifting block 30 on the base plate 10 for translation in the height direction Z. Specifically, the first guide assembly 20 may be mounted directly on the base plate 10, or may be mounted on the base plate 10 by other support structures.

Referring to fig. 1, a lifting block 30 is coupled to the first guide assembly 20 to translate in a height direction Z, and the lifting block 30 is provided with a mounting surface 31 at the top for integrally mounting the laser light path 100 and a first inclined surface 32 at the bottom. The lifting block 30 translates (i.e., lifts) in the height direction Z along the guide assembly. The mounting surface 31 is used for integrally mounting the laser light path 100, that is, the laser light path 100 is not required to be split, so that the integrity of the laser light path 100 can be ensured, and ash entering of the laser light path 100 is avoided.

The first position sensor 62 and the second position sensor 63 may be installed at a high position and a low position, respectively, as needed. When the sensing trigger 64 rises to trigger the first position sensor 62, the controller controls the rotation driver 53 to stop driving so that the elevating block 30 stops at the height, which is the highest point where the elevating seat rises. When the sensing trigger 64 is lowered to trigger the second position sensor 63, the controller controls the rotation driver 53 to stop driving so that the elevating block 30 stops at the height, which is the lowest point of the descent of the elevating seat.
