[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0025] Embodiment 1:

[0026] Referring to Figures 1-3 , a laser amplifier includes a laser amplifier body 1, and further includes: a housing assembly sleeved on the laser amplifier body 1, with internal threads provided inside the housing assembly, and the housing assembly is cylindrically arranged; an external thread ring 301 provided at one end of the laser amplifier body 1 close to the connection line; an external thread ring 302 provided at one end of the laser amplifier body 1 close to the emission end. The internal threads inside the housing assembly match the threads of the external thread ring 301 and the external thread ring 302 and can be threadedly connected. When the external thread ring 301 is threadedly connected to the internal threads, the entire housing assembly is sleeved on the laser amplifier body 1. When the external thread ring 302 is threadedly connected to the internal threads, a part of the housing assembly is sleeved on the laser amplifier body 1, and the rest is located outside the laser amplifier body 1, facing the emission direction of the emission end. The housing assembly includes a housing 201 and a housing 202. A thread ring is provided at the contact part between the two. The internal threads are provided inside the housing 201. The housing 201 and the housing 202 are threadedly connected to a connection ring 203 through the thread ring. The connection ring 203 is used to lock and fix the housing 201 and the housing 202. A plurality of sets of balls 205 are rotatably connected to one end of the housing 202 close to the emission end of the laser amplifier body 1. A limit ring 204 is provided on the internal threads of the housing 201. The limit ring 204 is used to limit the movement of the housing assembly and prevent it from falling off.

[0027] When this device is in use, it is connected to a laser emitter. Subsequently, by rotating the housing assembly, the internal threads are disengaged from the external thread ring 301. At this time, the housing assembly can be moved. Then, rotate again to threadedly connect the internal threads to the external thread ring 302, thereby completing the movement and fixation of the housing assembly. At this time, the user can hold the laser amplifier body 1 by hand, and the surface of the metal plate is contacted through the balls 205 to form a perpendicular, which is convenient for laser engraving.

[0028] After use, reset can be performed. After using for a period of time, if the balls 205 cannot roll normally and affect the comfort, at this time, the connection ring 203 can be rotated to separate the housing 201 and the housing 202. At this time, the housing 202 can be replaced with a new one, and then connected through the connection ring 203.

[0029] Embodiment 2:

[0030] Referring to Figures 1-3 , the laser amplifier is basically the same as that in Embodiment 1. Further, the housing assembly is made of transparent plastic material.

[0031] The material is not limited to plastic, and any transparent material is acceptable.

[0032] Through the arrangement of the casing assembly, when in use, the laser amplifier body can be stably vertically arranged through the casing assembly, and it can prevent others from directly contacting the laser, reducing the possibility of injury and facilitating use.

[0033] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes should be covered within the protection scope of the present invention.
