[0031] See also Figures 1 to 8 , this embodiment provides a laser structure 100 with adjustable stroke, which is mounted on a carrier 200. The laser structure 100 with adjustable stroke includes: a fixed seat 1, a sleeve 2 that can slide linearly along the fixed seat 1, a laser generator 3 connected to the sleeve 2, and an adjustment component that pushes the sleeve 2 to change the stroke. The adjustment component includes: an adjustment member 4 and an elastic member 5, the adjustment member 4 is telescopically connected to the fixed seat 1, and the adjustment member 4 is located at the rear end of the sleeve 2, and the elastic member 5 is connected to the fixed seat 1 and located at the front end of the sleeve 2. The adjusting member 4 is rotated or pushed so that the adjusting member 4 moves forward or backward along the fixing seat 1, and the sleeve 2 is synchronously pushed forward or backward along the fixing seat 1, and the laser generator 3 is fixedly connected to the sleeve 2, so the forward and backward stroke of the laser generator 3 can be synchronously adjusted. When the laser structure 100 with adjustable stroke is installed on the carrier 200, the position of the laser generator 3 can be fine-tuned again by adjusting the component, so as to achieve the best use state.

[0032] For details, please refer to Figure 7The fixing seat 1 is provided with an installation cavity 11, and the sleeve 2 is arranged in the installation cavity 11, and the installation cavity 11 and the sleeve 2 are connected with each other by a guide mechanism, so that the sleeve 2 maintains an axial static state during linear movement, that is, the sleeve 2 can move forward and backward along the length direction of the installation cavity 11, but the sleeve 2 itself will not rotate axially during the forward and backward movement.

[0033] The guide mechanism includes: a limiting protrusion 113 extending along the length direction of the installation cavity 11 and a limiting groove 211 recessed in the outer wall of the sleeve 2, or a limiting protrusion 211 extending along the length direction of the sleeve 2 and a limiting groove 113 recessed in the cavity wall of the installation cavity 11. That is, the sleeve 2 and the installation cavity 11 of the fixing seat 1 use a guiding mechanism of a limiting protrusion and a limiting groove for limiting guidance to prevent the two from axially rotating when moving forward and backward in the installation cavity, wherein the limiting protrusion and the limiting groove can be interchanged on the sleeve 2 and the fixing seat 1. In this embodiment, the limiting protrusion 113 and the limiting groove 211 are both strip-shaped protrusions or strip-shaped grooves.

[0034] like Figure 6 As shown, the adjusting member 4 is a nut, and a threaded portion 111 corresponding to the nut is provided inside the rear end of the installation cavity 11. The nut is screwed to the threaded portion 111, and the position of the sleeve 2 in the installation cavity 11 can be adjusted by rotating the nut.

[0035] Please refer again Figure 4 and Figure 7 The fixing seat 1 is also provided with a glue injection port 12 connected to the installation cavity 11, and the sleeve 2 is provided with a glue injection hole 212, and the glue injection port 12 is arranged in alignment with the glue injection hole 212. The glue injection port 12 is a strip-shaped hole. After assembly, the glue injection hole 212 is located below the glue injection port 12, and glue is injected into the sleeve 2 from the glue injection port 12 and the glue injection hole 212, so that the laser generator 3 is glued and fixed in the sleeve 2, and the two are moved and adjusted synchronously.

[0036] The fixing seat 1 is also provided with a locking hole 13, which extends from the outer wall of the fixing seat 1 to the mounting cavity 11, and a screw is threaded into the locking hole 13. When the sleeve 2 is adjusted to the optimal position, the screw is tightened so that the screw abuts against the outer wall of the sleeve 2, and finally the sleeve 2 and the fixing seat 1 are locked and fixed.

[0037] In this embodiment, the elastic member 5 is a spring, one end of the spring abuts against the front end of the sleeve 2 , and the other end of the spring abuts against the fixing seat 1 .

[0038] Specifically, the fixing seat 1 is further provided with an end cover 6, which covers the front end opening of the mounting cavity 11, and the end of the spring abuts against the end cover 6. The end cover 6 is also provided with a through hole 61 for laser emission, and the end cover 6 is connected to the fixing seat 1 with screws.

[0039] The diameter of the spring is larger than the outer diameter of the laser generator 3 , and the spring is sleeved on the outside of the laser generator 3 .

[0040] Please refer again Figure 7 A limit platform 112 is also provided on the cavity wall of the installation cavity 11 behind the threaded portion 111 , and the limit platform 112 is used to limit the stroke of the adjusting member 4 .

[0041] Please refer again Figure 8 The sleeve 2 includes: a tubular body 21 and a columnar tube cavity 22 arranged in the tubular body 21, and the laser generator 3 is inserted in the columnar tube cavity 22.

[0042] The following briefly introduces the adjustment process of the laser structure 100 with adjustable stroke:

[0043] After the adjustable stroke laser structure 100 is mounted on the carrier 200, the adjusting member 4 is rotated so that the relative position between the adjusting member 4 and the threaded portion 111 changes. When the nut is screwed inward, the sleeve 2 is pushed forward, and the laser generator 3 is driven forward synchronously, and the sleeve 2 compresses the elastic member 5; conversely, the nut is withdrawn from the threaded portion 111, and the sleeve 2 retreats under the elastic force of the elastic member 5, thereby driving the laser generator 3 to retreat. The above process completes the fine adjustment of the stroke of the laser generator 3, so that it is located at the best working position.

[0044] The laser structure with adjustable stroke of this embodiment is achieved by connecting the laser generator to the sleeve. The sleeve and the fixed seat can be linearly slidably assembled, and the position of the laser generator on the fixed seat can be changed by adjusting the nut. Therefore, after the laser is fixed to the carrier, the optical distance can be fine-tuned according to actual conditions to achieve the optimal optical distance position.

[0045] The above examples are only used to further illustrate the technical content of the utility model, so that readers can understand it more easily, but it does not mean that the implementation methods of the utility model are limited to this.
