[0025] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0026] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0027] like Figures 1-7 As shown, the present invention is a laser beam adjustment device, characterized by comprising a housing 1, a laser body 2, a laser tip 21, and a beam pressing plate 7; the laser body 2 is located inside the housing 1, and the laser tip 21 and the beam pressing plate 7 are respectively disposed on the laser body 2; the beam pressing plate 7 has three vertically distributed through holes 8, and semi-cylinders 82 are sequentially disposed in the three through holes 8; the semi-cylinders 82 are provided with an electric push rod 81 mounted on the housing 1, and under the push of the electric push rod 81, the two semi-cylinders 82 merge into one cylinder, and the larger end of the cylinder is fitted onto the laser tip 21 to reduce the size of the optical fiber emitted by the laser tip 21, thereby achieving precise positioning;

[0028] The outer shell 1 has a through hole 11. The distance between the upper and lower walls of the inner cavity of the light pressure plate 7 gradually decreases from front to back, and the end away from the laser body 2 is located in the through hole 11.

[0029] The laser beam adjustment device of the present invention pushes two semi-cylinders 82 together by an electric push rod 81 to form a cylinder. The larger end of the cylinder is fitted onto the laser end 21, thereby compressing the light emitted from the laser end 21 through the semi-cylinder 82 in the through hole 3, making the light thinner and achieving precise positioning.

[0030] Its working principle is as follows: First, after receiving the control signal, the electric push rod 81 extends and retracts, pushing the two semi-cylinders 82 to merge along the optical path direction, and the two merge into a cylinder. This cylinder fits perfectly onto the laser end 21. Then, inside the cylinder, the light passes through the vertically distributed through holes 8 and is compressed by the semi-cylinders 82, thereby reducing the beam diameter and achieving precise focusing.

[0031] Preferably, the outer shell 1 has two recessed holes 12 distributed vertically, and the two recessed holes 12 together form the same as the through hole 11; a baffle 71 is hinged to the light pressure plate 7, and the baffle 71 is located inside the recessed hole 12, so that only the opening of the light pressure plate 7 communicates with the interior of the outer shell 1 to prevent internal contamination.

[0032] Preferably, the outer shell 1 is provided with a support plate 35 and a motor 3. The support plate 35 is rotatably connected to the laser body 2, and the motor 3 is slidably connected to the outer shell 1. The output end of the motor 3 is provided with a drive shaft 31. A gear 32 is fixedly sleeved in the middle of the drive shaft 31. A half gear 33 meshes on the gear 32. Both ends of the half gear 33 are provided with connecting plates 34. The connecting plates 34 are installed on the laser body 2.

[0033] Motor 3 is connected to laser body 2 via drive shaft 31 and gear 32. Motor 3 and housing 1 are connected by a sliding connection to achieve relative movement in the left and right directions, allowing support plate 35 to slide along housing 1. When motor 3 starts, drive shaft 31 rotates, driving gear 32 to rotate. Since gear 32 meshes with half gear 33, which acts as an intermediate transmission component, laser body 2 can form a rotatable connection on support plate 35. Thus, motor 3 drives drive shaft 31 to rotate, and through the meshing of gear 32 and half gear 33, laser body 2 rotates horizontally, achieving precise adjustment and positioning of laser body 2 to meet the needs of various application scenarios. The entire workflow is as follows: motor 3 starts, drive shaft 31 rotates, gear 32 rotates and drives half gear 33, ultimately causing laser body 2 to rotate around support plate 35, thereby achieving precise directional adjustment.

[0034] The laser body 2 is provided with two protruding plates 22. Bolts 36 are rotatably mounted on the protruding plates 22 via bearings 9. The bolts 36 are screwed to the support plate 35. When the bolts 36 are removed, the laser body 2 can be replaced.

[0035] More preferably, a laser support plate 43 is slidably provided on the outer shell 1, the laser support plate 43 is in contact with the lower end of the laser body 2, the laser support plate 43 is provided with two push plates 42, and the push plates 42 are provided with rack plates 41; two gears 4 are fixedly sleeved on the drive shaft 31, and the gears 4 mesh with the rack plates 41.

[0036] The surface of the laser support plate 43 that contacts the laser body 2 is inclined from top to bottom, and a flat groove 44 is opened at the top of the laser support plate 43.

[0037] This technical solution uses a laser support plate 43 that slides on the outer casing 1 to make the laser body 2 make stable contact with the laser support plate 43. Two push plates 42 are installed on the laser support plate 43, and rack plates 41 are attached to the push plates 42. At the same time, two gears 4 are fixedly sleeved on the drive shaft 31. The gears 4 directly mesh with the rack plates 41, thereby achieving precise control of the laser support plate 43 and supporting the laser body 2, making the laser body 2 more stable when rotating.

[0038] The contact surface between the laser support plate 43 and the laser body 2 is designed to be inclined from top to bottom, which can effectively reduce friction and allow the laser body 2 to slide up and down more flexibly on the laser support plate 43. In addition, the flat groove 44 at the top of the laser support plate 43 further optimizes the stability of the laser body 2 when it moves to the highest point.

[0039] Preferably, two rings 5 ​​are rotatably sleeved on the drive shaft 31, and each ring 5 is provided with a spring telescopic rod 51 mounted on the outer shell 1. The spring telescopic rod 51 is in an unstretched and uncompressed state so as to ensure precise meshing of gear 32 and half gear 33. At the same time, compressing the spring telescopic rod 51 can separate gear 32 and half gear 33, so that the laser body 2 can be replaced.

[0040] Preferably, the outer shell 1 has two through holes 13 for the rack plate 41 to pass through, and the outer shell 1 is also provided with a U-shaped plate 6 so that the U-shaped plate 6 can be extended out of the through holes 13 for wrapping and forming protection.

[0041] It is understood that the above embodiments are merely exemplary implementations used to illustrate the principles of the present invention, and the present invention is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also considered to be within the scope of protection of the present invention.
