Outer edge be provided with threaded portion, the inner edge portion of described adjustable focal length protecgulum is available for lens and fixes；
Sleeve pipe, is hollow body, and described sleeve pipe is provided with dispensing hole, and the inner peripheral of described sleeve pipe can screw togather described threaded portion
Female thread；
Other semiconductor lasers device, is installed in described sleeve pipe, including switch, circuit board, power spring, laser discharger,
Described laser discharger is provided with multiple lead foots stretching out, and described lead foot is connected to described circuit board, on described circuit board
It is provided with described switch, one end of described circuit board then connects described power spring.
Preferably, the dispensing hole in described sleeve pipe is screwed hole.
Screwed hole in described sleeve pipe can coordinate the fixing spiral shell edge of installing.
The beneficial effects of the utility model are：Prop up the sleeve pipe inner edge portion in sleeve pipe by spring force, adjustable focus can be made
The female thread of the threaded portion away from protecgulum and sleeve pipe is in horizontal compression shape, so will not make adjustable focal length protecgulum via adjustment portion
After adjustment, gap can be produced because of thread engaging position.

Specific embodiment
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely description is it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under the premise of making creative work
The every other embodiment being obtained, broadly falls into the scope of this utility model protection.
Refer to each view of this creation of the 1st figure to the 4th figure system.
As shown in figures 1-4, the adjustable focal length holography laser devices of the present embodiment, including：Sleeve pipe 1, is hollow body, its
Inside it is equiped with other semiconductor lasers device 2, other semiconductor lasers device 2 includes switching 23, circuit board 22, power spring 6, laser light are sent out
Injection device 21, adjustment portion 34 front end face of adjustable focal length protecgulum 3 is in a taper knot being expanded outwardly in suitable angle by tube hub
The inner edge portion 32 of adjustable focal length protecgulum 3 sequentially inserted by lens 4 by structure 31, and inner edge portion 32 is available for lens 4 and fixes, and so that lens 4 is close to
In inner edge portion 32, the outer edge of adjustable focal length protecgulum 3 is provided with threaded portion 33, and sleeve pipe 1 is provided with dispensing hole 13, and inner circumferential
Edge is then provided with the female thread 11 that can screw togather adjustable focal length protecgulum 3 threaded portion 33, and is provided with spring 5 between lens 4 and sleeve pipe 1,
When the adjustment portion 34 rotation adjustment by adjustable focal length protecgulum 3, the threaded portion 33 of this adjustable focal length protecgulum 3 can be made to be screwed together in sleeve pipe
When female thread 11 in 1 adjusts, then can be supported as in the sleeve pipe inner edge portion 12 in sleeve pipe 1 by this spring 5 elastic force, so may be used
Make the threaded portion 33 of adjustable focal length protecgulum 3 and the female thread 11 in sleeve pipe 1 be in horizontal compression shape, so will not make via tune
After adjustable focal length protecgulum 3 is adjusted by whole 34, gap can be produced because of thread engaging position, the adjusted portion of the present embodiment 34 revolves
