[0018] Among them, by setting up the fixing mechanism 1, the entire device can be fixedly installed on the desktop, and when it needs to be placed on the ground, the fixing mechanism 1 can be detached from under the rotating mechanism 2, so as to facilitate the whole device to be stably placed on the ground. During the placement of the handheld laser radar, the movable clamping mechanism 5 is pulled to make the fixed clamping mechanism 4 and the movable clamping mechanism 5 move away from each other, so as to facilitate the laser radar to be placed between the fixed clamping mechanism 4 and the movable clamping mechanism 5 for fixing. Subsequently, when the laser radar detects the indoor environment, the setting of the rotating mechanism 2 can drive the laser radar to rotate all-roundly for detection of the indoor situation.
[0019] See also Figure 1 and Figure 2The fixed clamping mechanism 4 includes a first clamping plate 6 and a second clamping plate 7. The opposite sides of the first clamping plate 6 and the second clamping plate 7 are provided with a bottom fixing groove 8 for clamping and limiting the laser radar base. The tops of the first clamping plate 6 and the second clamping plate 7 are fixedly connected with a handle fixing plate 9 for fixing and limiting the laser radar handle position. A first limiting rod 11 is fixedly connected to one side of the first clamping plate 6. The first limiting rod 11 is slidably connected to the second clamping plate 7. A spring 12 is fixedly connected to one side of the first clamping plate 6 and located on the outer surface of the first limiting rod 11.

The inner walls of the bottom fixing groove 8 and the handle fixing plate 9 are covered with rubber pads.
[0020] Among them, when the handheld laser radar needs to be placed, pull the handle 10. The pulling of the handle 10 causes the second clip plate 7 to move along the first limit rod 11, so that the first clip plate 6 and the second clip plate 7 are separated from each other, so that the handheld laser radar can be placed, and then release the handle 10. The setting of the spring 12 can pull the first clip plate 6 and the second clip plate 7 closer to each other, and then the bottom fixing groove 8 and the handle fixing plate 9 can fix and lock the base and the handle position of the handheld laser radar.
[0021] See also Figure 1 , Figure 2 and Figure 3 The rotating mechanism 2 includes a block 20, a fixing seat 21, a mounting frame 22, a motor 23 and a slot 24. The top of the fixing mechanism 1 is fixedly connected with the block 20, the bottom of the fixing seat 21 is provided with a slot 24 engaged with the block 20, the top of the fixing seat 21 is fixedly connected with the mounting frame 22, the inside of the mounting frame 22 is fixedly installed with a motor 23, the output end of the motor 23 is fixedly connected to the mounting plate 3, and the top of the mounting frame 22 is fixedly installed with multiple groups of guide columns 25, and the top of the guide column 25 is rotatably connected with a ball 26 in contact with the bottom of the mounting plate 3.
[0022] Among them, when it is necessary to use the clamped handheld laser radar for indoor detection, start the motor 23 to operate, and the motor 23 can drive the mounting plate 3 to rotate, so as to drive the handheld laser radar clamped between the first clamping plate 6 and the second clamping plate 7 to perform rotation detection indoors. The guide column 25 and the ball 26 provided can support and limit the bottom of the mounting plate 3 to prevent shaking when driving the laser radar to rotate. When the rotating mechanism 2 needs to be placed on the ground, the block 20 and the slot 24 are disengaged from each other, so that the fixing seat 21 can be directly placed on the ground.
[0023] See also Figure 1 , Figure 2 and Figure 3 The fixing mechanism 1 includes a fixing frame 13, a threaded rod 14, a second limiting rod 15, a clamping plate 16 and a threaded sleeve 17. The fixing frame 13 is set to a "U" shape. The threaded rod 14 is rotatably connected inside the fixing frame 13. The second limiting rod 15 is fixedly connected inside the fixing frame 13 and located on both sides of the threaded rod 14. The threaded sleeve 17 is threadedly connected to the threaded rod 14. The outer surface of the second limiting rod 15 is slidably connected to the limiting sleeve 18. The clamping plate 16 is fixedly connected to the threaded sleeve 17 and the limiting sleeve 18. The bottom of the threaded rod 14 is fixedly connected to a knob 19.
[0024] When the entire device needs to be fixedly installed on the desktop, the knob 19 is rotated to rotate the threaded rod 14, and then the threaded sleeve 17 can be used to drive the clamping plate 16 to move upward, and the second limiting rod 15 and the limiting sleeve 18 can limit the clamping plate 16 to prevent the clamping plate 16 from shaking during the movement.

[0025] When in use, first, the entire device can be fixedly installed on the desktop by setting the fixing mechanism 1, and when it needs to be placed on the ground, the fixing mechanism 1 can be detached from the bottom of the rotating mechanism 2, so that the entire device can be stably placed on the ground. In the process of placing the handheld laser radar, the movable clamping mechanism 5 is pulled to make the fixed clamping mechanism 4 and the movable clamping mechanism 5 move away from each other, so that the laser radar is conveniently placed between the fixed clamping mechanism 4 and the movable clamping mechanism 5 for fixing. Then, when the laser radar detects the indoor environment, the setting of the rotating mechanism 2 can drive the laser radar to perform all-round rotation detection of the indoor situation. When the handheld laser radar needs to be placed, pull the handle 10. The pulling of the handle 10 makes the second clamping plate 7 move along the first limiting rod 11, so that the first clamping plate 6 and the second clamping plate 7 move away from each other. In this way, the handheld laser radar can be placed, and then the handle 10 is released. The setting of the spring 12 can pull the first clamping plate 6 and the second clamping plate 7 closer to each other, and then the bottom fixing groove 8 and the handle fixing plate 9 can be used for hand The base and the handle of the handheld laser radar are fixed and locked.

When it is necessary to place the rotating mechanism 2 on the ground When the clamping block 20 and the clamping slot 24 are disengaged from each other, the fixing seat 21 can be directly placed on the ground. When the entire device needs to be fixedly installed on the desktop, the knob 19 is rotated to rotate the threaded rod 14, and then the threaded sleeve 17 can be used to drive the clamping plate 16 to move upward, and the second limiting rod 15 and the limiting sleeve 18 can limit the clamping plate 16 to prevent the clamping plate 16 from shaking during the movement. In this way, the movable clamping plate 16 and the fixing frame 13 can fix the entire device on the desktop.
