[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] like Figures 1-4 As shown, a laser rangefinder includes a laser module 5 and a support base 1. A damped rotating seat 3 is rotatably connected to the upper surface of the support base 1. A swing seat 4, which swings vertically, is hinged to one side of the upper surface of the rotating seat 3. A mounting base 6 is fixedly mounted on the upper surface of the swing seat 4. Clamping discs 11 are provided on the inner walls of the mounting base 6. The laser module 5 is disposed within the support base 1 and clamped and fixed by the two clamping discs 11. The laser module 5 is a commonly used laser rangefinder. The laser module 5 is clamped and fixed to the mounting base by the relative movement of the two clamping discs 11. Within 6, the laser module 5 is oscillating up and down by driving one of the clamping disks 11 to rotate. In this solution, the position of the device is determined by fixing the position of the support base 1. When it is necessary to adjust the laser orientation of the laser module 5, the rotating seat 3 is rotated so that the rotational thrust on the rotating seat 3 is greater than the frictional force between the rotating seat 3 and the support base 1, thereby achieving the rotation of the rotating seat 3. After the orientation of the rotating seat 3 is adjusted, the oscillating seat 4 can oscillate up and down to drive one end of the mounting base 6 to oscillate up and down, thereby achieving the relative height adjustment of the left and right ends of the laser module 5 within the mounting base 6.

[0023] A through groove 19 is formed on the upper surface of the rotating seat 3 away from the hinge point of the swing seat 4. The relative inner wall of the through groove 19 is inserted into the swing end of the swing seat 4. The rotating plate 12 is connected to the relative inner wall of the through groove 19. The two side edges of the rotating plate 12 are arc edges with different radii. The two side edges of the rotating plate 12 are used to drive the upswing and downswing of the swing seat 4, respectively. A first arc-shaped groove 16 and a second arc-shaped groove 17 are formed on the side of the rotating plate 12 near the two side edges. One end of the first arc-shaped groove 16 and the second arc-shaped groove 17 coincide. The swing end of the swing seat 4 is fixedly installed with a clamping block 18 which is slidably connected with the first arc-shaped groove 16 and the second arc-shaped groove 17. One end of the first arc-shaped groove 16 is arranged at the intersection of the two side edges of the rotating plate 12, and the other end is away from the rotating position of the rotating plate 12. One end of the second arc-shaped groove 17 is arranged at the intersection of the two side edges of the rotating plate 12, and the other end is close to the rotating position of the rotating plate 12. When the rotating plate 12 rotates clockwise, the distal end of the first arc-shaped groove 16 swings upward and approaches the swing seat 4. By inserting the first arc-shaped groove 16 and the clamping block 18, the swing seat 4 can gradually swing upward with the clockwise rotation of the rotating plate 12. Figure 3 And Figure 4 When the rotating plate 12 rotates counterclockwise, the proximal end of the second arc-shaped groove 17 swings upward and approaches the swing seat 4. Therefore, under the action of gravity, the swing seat 4 will swing downward.

[0024] Conversely, when the rotating plate 12 rotates counterclockwise, the proximal end of the second arc-shaped groove 17 swings upward and approaches the swing seat 4. Therefore, under the action of gravity, the swing seat 4 will swing downward.

[0025] Further, in order to ensure the rotation of the rotating plate 12, a gear 7 is fixedly installed at the rotating position of the rotating plate 12 and extends outward through the swing seat 4. A rack 8 is inserted into the swing seat 4 and is in meshing connection with the gear 7. An electric push rod 9 is connected between the swing seat 4 and the rack 8. By extending and retracting the electric push rod 9, the connected rack 8 can be moved, and the meshing connected gear 7 can drive the rotating plate 12 to rotate in the corresponding direction.

[0026] In order to realize the clamping of laser modules 5 of different sizes, one end face of one of the clamping discs 11 is rotatably connected with a lead screw 10 which penetrates the mounting seat 6. The outer side edge of the mounting seat 6 is rotatably connected with a nut 2 which is in threaded connection with the lead screw 10. Two winches 15 are symmetrically installed on the facing end faces of the two clamping discs 11. The hawsers wound on the winches 15 penetrate the back of the clamping disc 11 and the other positions on the front of the clamping disc 11, and the end faces of the hawsers of the winches 15 are spherical. The hawsers of the winches 15 are used to bind and fix the laser modules 5. By rotating the two winches 15 on the clamping disc 11 to release a certain length of hawser, the two hawsers are wound around the laser modules 5, and the laser modules 5 of different shapes and sizes can be fixed between the two clamping discs 11.

[0027] The other clamping disc 11 end face is rotatably connected with the side wall of the mounting seat 6 and is fixedly provided with an angle ring 13 through the end, the surface of the angle ring 13 is hollow at each scale value, and the mounting seat 6 is provided with a pin 14 inserted into the hollow part of the angle ring 13, when the laser module 5 is clamped and fixed between the two clamping discs 11, the laser module 5 is rigidly connected and fixed with the two clamping discs 11, so that the clamping disc 11 connected with the angle ring 13 can drive the laser module 5 to rotate to realize the inclination adjustment by rotating the angle ring 13, and the position of the angle ring 13 can be fixed by inserting the pin 14 into the hollow part at different scale values of the angle ring 13, so that the inclination of the laser module 5 is fixed.

[0028] The working principle is that the laser module 5 is placed between the two clamping discs 11 in the mounting seat 6, the screw rod 10 is held, the clamping disc 11 at the end is moved by rotating the nut 2, until the two clamping discs 11 clamp the two sides of the laser module 5, and the laser module 5 is fixed by the two winches 15 on the clamping disc 11, when in use, the laser module 5 is swung up and down by rotating the angle ring 13, or the rotating seat 3 is rotated by rotating the rotating seat 3, so that the rotating seat 3 is rotated, and the laser module 5 is horizontally rotated, after the rotating seat 3 is adjusted, the mounting seat 6 at one end is swung up and down by swinging the swinging seat 4, so that the relative height of the laser module 5 in the mounting seat 6 is adjusted.

[0029] The wiring diagram of the laser module 5, the servo motor and the electric push rod 9 in the utility model belongs to the common knowledge in the field, the working principle is a known technology, and the type is selected according to actual use, so the control mode and wiring arrangement of the laser module 5, the servo motor and the electric push rod 9 are not explained in detail.
