[0042] Reference Figure 13 and Figure 14As shown, a distance measuring receiving device based on photoelectric detection is shown, the left side of the outer surface of the rotating rod 14 is fixedly connected with a support bar 4, the left side of the support bar 4 is fixedly connected with a third screw 41, the outer surface of the left end of the third screw 41 is threadedly connected with a rotating member 43, the rotating member 43 is used to rotate on the outer surface of the third screw 41, the outer surface of the third screw 41 is fixedly sleeved with a storage spring 42, the left end of the storage spring 42 is fixedly connected to the right side of the rotating member 43, the storage spring 42 is used to drive the rotating member 43 to reset and move, the left side of the rotating member 43 is symmetrically slidably connected with a grinding member 44, the grinding member 44 is used for polishing the wall surface. The outer surface of the right side of the polishing piece 44 is fixedly sleeved with a compression spring 45. The right end of the compression spring 45 is fixedly connected to the left side of the rotating piece 43. The compression spring 45 is used to drive the polishing piece 44 to reset. When the polishing piece 44 is driven to rotate by the rotating piece 43, the polishing piece 44 can clean the wall surface, so that the suction cup 17 can be better adsorbed on the wall surface, and the stability of adsorption is improved, so that the rangefinder 1 will not be affected by shaking or falling off during the measurement process. The accuracy of the measurement result is improved. Reliability and accuracy of the measurement.

[0043] The complete working principle and steps of the above embodiment are as follows:

[0044] refer to Figures 1 to 6 As shown, when the distance measurement receiving device is in the initial state, the distance meter 1 and the suction pump 16 are in the closed state, the pressure spring 110 and the linear spring 112 are in the natural relaxation state, and the side of the first latch 19 close to each other is clamped in the annular groove at the top of the outer surface of the rotating rod 14;

[0045] When using this ranging and receiving device to measure a wall surface, the rangefinder 1 can be turned on. The top of the rangefinder 1 can emit laser pulses to measure the distance to the wall surface. When the operator needs to move horizontally for multiple measurements, the suction cup 17 can be attached to the wall surface and the suction pump 16 can be started. At this time, the bottom of the suction pump 16 can suck air inside the air pipe 15, and the air pipe 15 can suck air inside the suction cup 17 to make the suction cup 17 in a negative pressure state. The left end of the suction cup 17 can firmly adsorb on the wall surface. At this time, the operator can move the rangefinder 1 to the right. When the rangefinder 1 moves to the right, it can drive the rotating ring 11 to move simultaneously. When the rotating ring 11 moves to the right, it can drive the sliding ring 12 to move simultaneously. At this time, the sliding ring 12 can slide to the right on the outer surface of the measuring rod 13, so that the rangefinder 1 can move horizontally to the right. And when the sliding ring 12 slides to the right on the outer surface of the measuring rod 13, the scale on the outer surface of the measuring rod 13 can be observed, so that the operator can know the distance that the rangefinder 1 moves. When the staff needs to measure at a lower place, the measuring rod 13 can be slid down. When the measuring rod 13 moves down, it will drive the first pin 19 to slide simultaneously through the fixing rod 18. When the first pin 19 slides down, the mutually approaching sides of the first pins 19 can disengage from the annular groove on the outer surface of the top of the rotating rod 14, and the first pins 19 are urged to slide away from each other. When the first pins 19 slide, they will drive the compression spring 110 to move to the stretched state. As the measuring rod 13 continues to slide down, it will drive the first pins 19 to move into another annular groove on the outer surface of the rotating rod 14. And the compression spring 110 in the stretched state will drive the first pins 19 to move towards each other, so that the mutually approaching ends of the first pins 19 are clamped in another annular groove on the outer surface of the rotating rod 14, so that the height of the measuring rod 13 can be adjusted. And when the measuring rod 13 moves down, it can drive the rotating ring 11 to move simultaneously through the sliding ring 12. When the rotating ring 11 moves, it can drive the rangefinder 1 to move simultaneously, so as to adjust the height of the rangefinder 1, so that the rangefinder 1 can move vertically to adapt to different height measurements, and it can also increase the stability when the rangefinder 1 moves, avoiding the shaking and tilting generated when holding the rangefinder 1 to move, thereby improving the measurement accuracy and making the measurement results more reliable.

[0046] When the operator needs to perform a horizontal measurement, the rangefinder 1 can be flipped downward. When the rangefinder 1 is flipped downward, it will drive the rotating ring 11 to rotate on the outer surface of the sliding ring 12. As the rotating ring 11 rotates, the left end of the second pin 111 will disengage from the round hole on the right side of the rotating ring 11, and it will also cause the second pin 111 to slide to the right. When the second pin 111 slides to the right, it will drive the linear spring 112 to move to a stretched state. When the rotating ring 11 continues to rotate, the left end of the second pin 111 can be docked with another round hole on the right side of the rotating ring 11, and the stretched linear spring 112 can drive the second pin 111 to move to the left, so that the left end of the second pin 111 is clamped in another round hole on the right side of the rotating ring 11, thereby restricting the rotating ring 11. When the rotating ring 11 drives the rangefinder 1 to flip, the rangefinder 1 can be flipped smoothly, reducing the error generated during the measurement of the rangefinder 1.

[0047] When the operator needs to remove the rangefinder 1, the suction pump 16 can be turned off. At this time, the bottom of the suction pump 16 can stop sucking air into the inside of the suction cup 17 through the air pipe 15, so that the inside of the suction cup 17 is released from the negative pressure state, enabling the operator to easily remove the suction cup 17 from the wall.

[0048] Reference Figures 7 to 9 As shown, when the ranging and receiving device is in the initial state, the winder 25 is in the closed state, the pull rope 26 is in the taut state, and the first torsion spring 27 is in the natural and relaxed state;

[0049] When the operator needs to measure a wall seam or an inaccessible place, the operator can hold the outer surface of the grip 24 and rotate the right end of the threaded sleeve 23. As the threaded sleeve 23 rotates, it will cause the first screw rod 22 to move leftward. When the first screw rod 22 moves leftward, it will drive the movable end of the pull rope 26 to move leftward with a delay. When the movable end of the pull rope 26 moves leftward, it will drive the limit post 2 to move simultaneously. When the limit post 2 moves leftward, it will drive the left end of the pull rope 26 to move simultaneously. At this time, the right end of the pull rope 26 can be pulled out from the inside of the winder 25, and when the limit post 2 moves leftward, it will drive the air pipe 15 to move simultaneously through the rotating rod 14, so that the distance measuring instrument 1 can measure some inaccessible places or hard-to-reach positions, expanding the measurement range. When the operator needs to adjust the angle detected by the distance measuring instrument 1, the operator can start the winder 25 to wind the pull rope 26. At this time, the pull rope 26 wound around the outer surface of the left end of the limit post 2 will move rightward, and when the pull rope 26 moves, it can also drive the limit post 2 to rotate. When the limit post 2 rotates, it can drive the rotating rod 14 to rotate simultaneously. As the rotating rod 14 rotates, it will drive the first torsion spring 27 to rotate to the energy storage state, and when the rotating rod 14 rotates, it can drive the air pipe 15 to swing, and then drive the distance measuring instrument 1 to swing simultaneously through the air pipe 15, so as to change the measurement angle of the distance measuring instrument 1, enabling the distance measuring instrument 1 to adapt to different terrains for all-round measurement and improving the flexibility and adaptability of the measurement.

[0050] When the operator needs to retract the distance measuring instrument 1, the operator can rotate the right end of the threaded sleeve 23 in the reverse direction. When the threaded sleeve 23 rotates in the reverse direction, it will drive the first screw rod 22 to move rightward. When the first screw rod 22 moves rightward, it will drive the rotating rod 14 to move rightward through the limit post 2. When the limit post 2 moves rightward, it will cause the pull rope 26 to move to a slack state. At this time, the first torsion spring 27 in the energy storage state will drive the limit post 2 to rotate in the reverse direction. When the limit post 2 rotates in the reverse direction, it will cause the outer surface of the left end of the pull rope 26 to be re-wound around the outer surface of the limit post 2, and when the limit post 2 rotates in the reverse direction, it will drive the rotating rod 14 to rotate simultaneously. When the rotating rod 14 rotates back to its original position, it will drive the distance measuring instrument 1 to swing back to its original position through the air pipe 15, so that when the distance measuring instrument 1 is retracted, the distance measuring instrument 1 can swing back to its initial state again.

[0051] Reference Figures 10 to 12As shown, when the operator needs to place the rangefinder 1 on the waterlogged ground for measurement, the operator can turn the rotating rod 34 counterclockwise. At this time, the front side of the left end of the rotating rod 34 will fit against the rear end of the front first footrest 32 and cause the front first footrest 32 to flip counterclockwise. When the first footrest 32 flips, it will drive the front second torsion spring 33 to rotate to the energy storage state, thus preventing the first footrest 32 from affecting the swing of the rotating rod 34. As the rotating rod 34 continues to swing, the front side of the left end of the rotating rod 34 will disengage from the rear end of the front first footrest 32, and the front second torsion spring 33 in the energy storage state will drive the front first footrest 32 to swing back to its original position. When the rotating rod 34 swings counterclockwise, it will drive the second screw 35 to rotate simultaneously. When the second screw 35 rotates, it will cause the sliding column 31 to move downward on the outer surface of the guide rod 36. When the sliding column 31 moves downward, it will drive the first footrest 32 and the second footrest 38 to move downward, so that the bottoms of the first footrest 32 and the second footrest 38 can support on the ground. At this time, when the rotating rod 34 continues to swing counterclockwise, the front side of the right end of the rotating rod 34 will fit against the left side of the front second footrest 38 and cause the front second footrest 38 to move to the right. When the front second footrest 38 moves to the right, it will drive the front sliding block 37 to move simultaneously. At this time, the front sliding block 37 will slide counterclockwise on the outer surface of the right end of the sliding column 31. When the front sliding block 37 slides, it will cause the front return spring 310 to move to the stretched state and the helical spring 311 to move to the compressed state. When the rotating rod 34 swings again, the front side of the right end of the rotating rod 34 will fit against the rear end of the front second footrest 38 and drive the front second footrest 38 to swing to the side away from the second screw 35. When the front second footrest 38 swings, it will drive the third torsion spring 39 to rotate to the energy storage state. When the rotating rod 34 swings 180 degrees, the front side of the right end of the rotating rod 34 will disengage from the rear end of the front second footrest 38. The front third torsion spring 39 in the energy storage state will drive the front second footrest 38 to swing back to its original position, and the helical spring 311 in the compressed state will drive the front second footrest 38 to return to the initial state through the front sliding block 37. Thus, the position of the supports of the first footrest 32 and the second footrest 38 can be adjusted by moving the rotating rod 34. When the first footrest 32 and the second footrest 38 support on the ground, it can prevent the rangefinder 1 from being contaminated, and it can also make it convenient for the operator to read the data of the rangefinder 1, improving the convenience of operation.

[0052] When the operator needs to reset the first leg 32 and the second leg 38, the operator can rotate and swing the rotating rod 34 counterclockwise so that the rear side of the right end of the rotating rod 34 fits against the right end of the front second leg 38 and pushes the front second leg 38 to the left. When the front second leg 38 moves to the left, it will drive the front sliding block 37 to move at the same time, and the front sliding block 37 will slide counterclockwise on the outer surface of the right end of the sliding column 31. When the front sliding block 37 swings counterclockwise, it will prompt the coil spring 311 to move to a stretched state, and the front reset spring 310 to move to a compressed state. As the rotating rod 34 continues to swing, it will prompt the rear side of the right end of the rotating rod 34 to squeeze the front side of the front second leg 38, so that the front second leg 38 swings to the side close to the second screw rod 35. At this time, when the rotating rod 34 swings again, it will disengage from the outer surface of the front second leg 38. , and the third torsion spring 39 on the front side in the power storage state will drive the second foot support 38 on the front side to reset and swing, and the return spring 310 on the front side in the compressed state will drive the second foot support 38 on the front side to reset to the initial state through the sliding block 37 on the front side, so that the second foot support 38 on the front side will not affect the reset and swing of the rotating rod 34, and when the rotating rod 34 then resets and swings, the rear side of the left end of the rotating rod 34 will fit the front side of the first foot support 32 on the front side and prompt the first foot support 32 on the front side to swing toward the side close to the guide column 3, and when the first foot support 32 on the front side swings, it will drive the second torsion spring 33 on the front side to rotate to the power storage state, thereby preventing the first foot support 32 on the front side from affecting the reset and swing of the rotating rod 34, and after the rotating rod 34 is reset, the second torsion spring 33 on the front side in the power storage state will drive the first foot support 32 on the front side to reset and swing, so that the first foot support 32 on the front side also returns to the initial state.

[0053] refer to Figure 13 and Figure 14 As shown, the operator fits the left end of the suction cup 17 between the walls, and the left end of the grinding piece 44 will be preferentially fitted to the wall. As the support bar 4 drives the rotating piece 43 to move to the left through the third screw 41, the rotating piece 43 can move the compression spring 45 to a stretched state. As the third screw 41 is gradually pushed to the left, the rotating piece 43 can gradually move to the right and rotate on the outer surface of the third screw 41. When the rotating piece 43 rotates, it can drive the grinding piece 44 to rotate at the same time. At this time, the left side of the grinding piece 44 can When polishing the wall, as the rotating part 43 gradually moves to the right, the force storage spring 42 will be prompted to move to the force storage state, and when the rotating part 43 moves, the compression spring 45 in the stretched state will be prompted to drive the polishing part 44 to move to the left, and the left side of the polishing part 44 can continue to fit the wall for polishing, so that the suction cup 17 can be better adsorbed on the wall, and the stability of adsorption is improved, so that the rangefinder 1 can be kept from shaking or falling off during the measurement process, which will affect the accuracy of the measurement result.

[0054] As the operator moves the rotating rod 14 to the right, the rotating rod 14 will drive the third screw rod 41 to move simultaneously through the support bar 4. When the third screw rod 41 moves to the right, it will drive the left side of the grinding piece 44 to disengage from the wall surface through the rotating part 43. At this time, the energy storage spring 42 in the energy storage state can drive the rotating part 43 to move to the initial state.
