[0028] See also Figure 1-8 The anti-bias device for a laser pointer in an underground coal mine comprises a frame 1, a rotating screw rod 2 is rotatably connected to the top of the frame 1, one end of the rotating screw rod 2 passes through the lifting block 3 and is threadedly connected to the lifting block 3, the lifting block 3 is rotatably connected to a connecting rod 4, one end of the connecting rod 4 is rotatably connected to a connecting arm 5, one end of the connecting arm 5 is rotatably connected to a fixed arm 6, and one end of the fixed arm 6 is fixedly installed with the inner top of the frame 1, and the other end of the connecting arm 5 is rotatably connected to a connecting frame 28, one end of the connecting arm 5 is fixedly connected to the fixed arm 6 at the inner top of the frame 1, and the other end is connected to the lifting block 3 through the connecting rod 4, forming a stable triangular support structure, which not only enhances the load-bearing capacity of the lifting block, but also ensures the stability during the lifting process, reduces shaking and deviation, and can accurately control the lifting and lowering movement of the lifting block 3 in the vertical direction through the rotation of the rotating screw rod 2, and the height of the entire structure can be adjusted according to actual needs, thereby increasing the flexibility and adaptability of the equipment.

[0029] Wherein; both sides of the frame 1 are rotatably connected with a rotating screw rod 2 17, and both sides of the frame 1 are welded with a plug-in sleeve shaft 18, and one end of the rotating screw rod 2 17 extends into the interior of the plug-in sleeve shaft 18, and one end of the rotating screw rod 2 17 penetrates the extrusion block 19 and is threadedly connected with the extrusion block 19, and the rotation of the rotating screw rod 2 17 can accurately control the position of the extrusion block 19, so the extrusion force exerted on the movable plate 21 can be conveniently adjusted, thereby controlling the depth of the rivet on the side of the movable plate 21 inserted into the inner wall of the fixing hole, and the two sides of the inner wall of the plug-in sleeve shaft 18 are fixedly connected with a connecting plate 20, and the two connecting plates 20 are slidably connected with the movable plate 21, and the two movable plates 21 are provided with rivets 23 on the sides away from each other, and the four corners of the side of the movable plate 21 are fixedly connected with a connecting spring 22, and one end of the connecting spring 22 is fixedly connected to the inner wall of the plug-in sleeve shaft 18, when the extrusion block 19 contacts the extrusion of the movable plate 21, the connecting spring 22 can restore the movable plate 21 and its rivet 23 to their original positions through the action of elastic force.

[0030] The inner bottom of the connecting frame 28 is rotatably connected to the rotating rod 29, and both ends of the rotating rod 29 are provided with stabilizing blocks 30, and the tops of the two ends of the two stabilizing blocks 30 are abutted against the supporting frame 31, and the top of the supporting frame 31 is fixedly installed with the laser pointer body 11. The setting of the stabilizing blocks 30 enhances the supporting stability of the rotating rod 29 under the supporting frame 31. They not only prevent the rotating rod from bending or deflecting when bearing weight, but also ensure the stability of the laser pointer body during operation, and reduce the error caused by vibration or external force interference.

[0031] Among them; the top of the other end of the connecting arm 5 is fixedly connected to a fixed block 7, the fixed block 7 is rotatably connected to an adjusting screw 8, one end of the adjusting screw 8 passes through a moving block 9 and is threadedly connected to the moving block 9, the moving block 9 is rotatably connected to a connecting rod 10, and one end of the connecting rod 10 is fixedly connected to the top of the connecting frame 28.

[0032] Among them, the top of the frame 1 is rotatably connected with a connecting shaft 12, one end of the connecting shaft 12 is coaxially fixedly connected with a bevel gear 13, the bevel gear 13 is meshed with a bevel gear 14, the bevel gear 14 is coaxially fixedly connected with a worm 15, and the worm 15 is rotatably connected to the frame 1, one end of the worm 15 is meshed with a worm wheel 16, and the worm wheel 16 is coaxially fixedly connected with the other end of the rotating screw 17.

[0033] Among them; the rotating screw rod 2 is coaxially fixedly connected with a spur gear 24, the spur gear 24 is provided with a telescopic tooth 25, the spur gear 24 is meshed with a spur gear 26, and the spur gear 26 is coaxially fixedly connected with the connecting shaft 12, and the spur gear 26 is provided with a telescopic tooth 27. By controlling the extension and retraction of the telescopic tooth 24 and the telescopic tooth 27, the meshing relationship between the spur gear 24 and the spur gear 26 can be effectively realized. When the telescopic tooth 24 and the telescopic tooth 27 are extended, the rotating spur gear 24 can drive the spur gear 26 to rotate together, and the two form a meshing relationship. When the telescopic tooth 24 and the telescopic tooth 27 are retracted, the spur gear 24 and the spur gear 26 are released from the meshing relationship.

[0034] Among them, the shape of the connecting rod 10 is L-shaped.

[0035] Among them, the number of bevel gears 14 is two.

[0036] Working principle: when in use, first, accurately insert the plug-in sleeve shafts 18 on both sides of the device into the preset fixing holes to achieve preliminary positioning, and then, by rotating the rotating screw 2, this action drives the rotation of the spur gear 24. When the telescopic tooth 25 and the telescopic tooth 26 are both in the extended state, the spur gear 24 can effectively drive the spur gear 27 and its coaxially fixed connecting shaft 12 to rotate synchronously, and the rotation of the connecting shaft 12 further promotes the rotation of the bevel gear 13, and drives the bevel gear 2 14 and its coaxially fixed worm 15 to rotate through the meshing relationship. The meshing action of the worm 15 and the worm wheel 16 causes the worm wheel 16 to rotate accordingly, thereby driving the rotating screw 2 17 to rotate. The rotation of the rotating screw 2 17 eventually causes the extrusion block 19 threaded at one end thereof to rotate along the rotating screw 1 7, during this process, the extrusion block 19 applies pressure to the movable plates 21 on both sides, pushing the movable plates 21 to move outward until the rivets fixed on the sides of the movable plates 21 pass through the plug-in sleeve shaft 18 and are firmly inserted into the inner wall of the fixing hole, thereby achieving a stable installation of the device. In addition, while the device is being installed, the rotation of the rotating screw rod 2 also drives the lifting block 3 to perform lifting and lowering movements along its trajectory. The movement of the lifting block 3 is transmitted to the connecting arm 5 through the connecting rod 4 to adjust the pitch angle of the connecting arm 5. When the connecting arm 5 reaches the desired pitch angle, the movable block 9 threadedly connected to it can be controlled to move on the connecting rod 2 10 by rotating the adjusting screw rod 8, thereby driving the connecting frame 28 connected to one end of the connecting rod 2 10 to rotate left and right until the connecting frame reaches the ideal orientation angle.

[0037] Secondly, during the use of the device, if it encounters external force and causes the whole device to shake, this dynamic change is cleverly resolved by the stabilizing component. Specifically, the rotating rod 29 connected to the bottom of the connecting frame 28 is a key component that can sense and respond to the shaking of the device. When the device shakes, the rotating rod 29 will swing left and right accordingly. This swinging action effectively offsets the lateral force generated by the sliding of the device, thereby reducing the amplitude of the shaking.

[0038] Furthermore, the stabilizing blocks 30 disposed at both ends of the rotating rod 29 will also swing forward and backward when the rotating rod swings. This forward and backward swinging mechanism further enhances the stabilizing effect. Through the multi-directional force balancing effect, the vibration of the device is more comprehensively offset. The top of the stabilizing block 30 is in close contact with the support frame 31, and the laser pointer body 11 is installed on the support frame 31. Therefore, when the stabilizing block 30 effectively offsets the vibration, the support frame 31 and the laser pointer body 11 can quickly return to the original stable position, ensuring the accuracy and precision of the laser pointing.
