At the same time, the first reset spring 17 accumulates force so that the telescopic rod 4 can move up and down. During the movement of the telescopic rod 4, the buffer spring 18 buffers the movement of the telescopic rod 4 to prevent the telescopic rod 4 from moving too fast and colliding with the bottom of the first slide groove 3, causing damage to the equipment. A second slide groove 20 is opened on both sides of the telescopic rod 4, and a slider 21 is fixedly connected to the bottom of both sides of the telescopic rod 4. The surface of the slider 21 is slidably connected to the inside of the second slide groove 20. The user pulls the first handle 16 to drive the first limit rod 15 to disengage from the inside of the first limit hole 12, thereby releasing the restriction on the telescopic rod 4. At the same time, the first return spring 17 accumulates force so that the telescopic rod 4 can move up and down. During the movement of the telescopic rod 4, the slider 21 slides inside the second slide groove 20 to limit the moving range of the telescopic rod 4 and prevent the telescopic rod 4 from disengaging from the inside of the first slide groove 3.

[0027] Reference Figure 1 , Figure 3 , Figure 4 and Figure 6As shown, specifically, a plurality of second limiting holes 22 are provided at the bottom of the surface of the second connecting rod 6, and the second limiting holes 22 are evenly distributed at the bottom of the surface of the second connecting rod 6. A second through hole 23 is provided on the surface of the connecting tube 5, and a second limiting rod 24 is slidably connected to the inside of the second through hole 23. The surface of the second limiting rod 24 is slidably connected to the inside of the second limiting hole 22, and a second handle 25 is fixedly connected to the right end of the second limiting rod 24. The user pulls the second handle 25 to drive the second limiting rod 24 to disengage from the inside of the second limiting hole 22, thereby releasing the restriction on the second connecting rod 6 and allowing the second connecting rod 6 to be engaged. The connecting rod 6 can be rotated inside the connecting tube 5. By adjusting the direction, the receiver body 11 can receive signals more stably. After adjusting the direction, the second limiting rod 24 is inserted into the second limiting hole 22 through the second through hole 23 to fix the direction of the receiver body 11. The left end of the second handle 25 is fixedly connected to the second reset spring 26. The top of the second reset spring 26 is fixedly connected to the surface of the connecting tube 5. The user pulls the second handle 25 to drive the second limiting rod 24 to disengage from the second limiting hole 22, thereby releasing the restriction on the second connecting rod 6. At the same time, the second reset spring 26 The spring 26 accumulates force. After the direction of the receiver body 11 is adjusted, the second handle 25 is released. Under the action of the second reset spring 26, the second limiting rod 24 is driven to insert into the second limiting hole 22 to limit the second connecting rod 6 and fix the direction of the receiver body 11. The top of the connecting piece 7 is fixedly connected to a fixing plate 27. The right end of the fixing plate 27 is provided with an arc-shaped groove 28.

The right end of the threaded rod 29 is fixedly connected to a knob 30. The user rotates the knob 30 to drive the screw The threaded rod 29 moves outward to release the friction between the knob 30 and the fixed plate 27, so that the rotating rod 9 can rotate. While the rotating rod 9 is rotated, the threaded rod 29 slides inside the arc-shaped slide groove 28 to limit the rotation angle of the rotating rod 9. During the rotation of the rotating rod 9, the angle of the receiver body 11 changes, which facilitates the receiver body 11 to receive signals more stably. After adjusting the angle of the receiver body 11, the knob 30 is rotated to drive the threaded rod 29 to move inward. At the same time, the knob 30 abuts against the fixed plate 27, increasing the friction to fix the position of the rotating rod 9, so that the angle of the receiver body 11 is fixed.

[0028] The practical working principle of the present invention is that the user pulls the first limiting rod 15 outwards to disengage from the first limiting hole 12, thereby releasing the restriction on the telescopic rod 4, so that the telescopic rod 4 can move up and down. After the telescopic rod 4 is moved to the required position, the first limiting rod 15 is inserted through the first through hole 14 into the first limiting hole 12 to fix the position of the telescopic rod 4, so that the user can adjust the height of the receiver body 11 as needed, thereby stably receiving the signal, and pulling the first handle 16 drives the first limiting rod 15 to disengage from the first limiting hole 12, thereby releasing the restriction on the telescopic rod 4. At the same time, the first reset spring 17 accumulates force, so that the telescopic rod 4 can move up and down. After the telescopic rod 4 is moved to the required position, the first handle 16 is released, and the first reset spring 17 is in the state of releasing the first reset spring 17. The first limit rod 15 is automatically inserted into the first limit hole 12 by the action, and the position of the telescopic rod 4 is limited. The first handle 16 is pulled to drive the first limit rod 15 to disengage from the first limit hole 12, and the restriction on the telescopic rod 4 is released. At the same time, the first return spring 17 accumulates force, so that the telescopic rod 4 can move up and down. During the movement of the telescopic rod 4, the buffer spring 18 buffers the movement of the telescopic rod 4 to prevent the telescopic rod 4 from moving too fast and colliding with the bottom of the first slide groove 3, causing damage to the equipment. The first handle 16 is pulled to drive the first limit rod 15 to disengage from the first limit hole 12, and the restriction on the telescopic rod 4 is released. At the same time, the first return spring 17 accumulates force, so that the telescopic rod 4 can move up and down. During the movement of the telescopic rod 4, The slider 21 slides inside the second slide groove 20 to limit the moving range of the telescopic rod 4 to prevent the telescopic rod 4 from being separated from the first slide groove 3. The user pulls the second handle 25 to drive the second limiting rod 24 to be separated from the second limiting hole 22, thereby releasing the restriction on the second connecting rod 6, so that the second connecting rod 6 can rotate inside the connecting tube 5. By adjusting the direction, the receiver body 11 can receive signals more stably. After adjusting the direction, the second limiting rod 24 is inserted into the second limiting hole 22 through the second through hole 23 to fix the direction of the receiver body 11. The second handle 25 is pulled to drive the second limiting rod 24 to be separated from the second limiting hole 22, thereby releasing the restriction on the second connecting rod 6. At the same time, the second reset spring 26 is used to store force. After adjusting the direction of the receiver body 11, the second handle 25 is released. Under the action of the second reset spring 26, the second limiting rod 24 is driven to be inserted into the second limiting hole 22 to limit the second connecting rod 6 and fix the direction of the receiver body 11. The knob 30 is rotated to drive the threaded rod 29 to move outward, and the friction between the knob 30 and the fixing plate 27 is released so that the rotating rod 9 can rotate. While rotating the rotating rod 9, the threaded rod 29 slides inside the arc-shaped slide groove 28 to limit the rotation angle of the rotating rod 9. During the rotation of the rotating rod 9, the angle of the receiver body 11 changes, which facilitates the receiver body 11 to receive signals more stably. After adjusting the angle of the receiver body 11, the knob 30 is rotated to drive the threaded rod 29 to move inward.At the same time, the knob 30 abuts against the fixing plate 27, increasing the friction force to fix the position of the rotating rod 9, so that the angle of the receiver body 11 is fixed.
