A fourth axial hole 401 is provided in the middle of one side of the receiver 1, and an adjustment mechanism 6 is rotatably provided inside the fourth axial hole 401. A driving mechanism 7 is fixedly provided on the top of the turntable 3, located on one side of the side plate 4.

[0029] In this embodiment, the transmission mechanism 8 includes a rotating shaft 801, and two groups of fifth shaft holes 402 distributed up and down are opened in the middle of a side surface of the side plate 4 close to the receiver 1. The two groups of fifth shaft holes 402 are respectively located at the top and bottom of the fourth shaft hole 401. The rotating shaft 801 is rotatably connected inside the fifth shaft hole 402. A transmission gear 802 is fixedly sleeved on the outer periphery of one end of the rotating shaft 801 close to the driving motor 701. The transmission gear 802 is meshed with the driving gear 702. The driving gear 702 rotates to drive the two groups of transmission gears 802 meshed therewith to rotate, thereby driving the rotating shaft 801 and the two groups of driving gears 803 to rotate.

[0030] In this embodiment, a transfer gear 803 is movably sleeved on the outer periphery of the end of the rotating shaft 801 away from the transmission gear 802, and a group of spline blocks 804 are fixedly connected to the inner wall of the transfer gear 803.

A sleeve 806 is fixedly connected to the side of the transfer gear 803 close to the turntable 3. The sleeve 806 is movably sleeved on the outer periphery of the rotating shaft 801, and a ring is opened on the outer wall of the sleeve 806. The slot 807 can slide by arranging the transfer gear 803 on the periphery of the rotating shaft 801 so that the transfer gear 803 can be slidably slid in the direction of the driven gear 605, so that the driven gear 605 can be driven to rotate and power transmission can be achieved. In any case, the power transmission to the driven gear 605 can be released. By setting the sliding connection relationship between the spline block 804 and the spline slot 805, the transfer gear 803 and the rotating shaft 801 are rotationally limited while ensuring the sliding of the transfer gear 803 along the rotating shaft 801, so as to avoid relative twisting of the transfer gear 803 and the rotating shaft 801.

[0031] In this embodiment, the transfer mechanism 9 includes two groups of electric push rods 901 distributed up and down, and the electric push rods 901 are fixedly connected to the side of the turntable 3 close to the drive motor 701. Two groups of through holes 403 distributed up and down are opened on one side of the turntable 3. The two groups of through holes 403 are located on the sides of the two groups with the fifth shaft holes 402. The output shaft of the electric push rod 901 movably passes through the through hole 403, and the outer peripheral fixed sleeve of the output end of the electric push rod 901 is provided with a fixed rod 902 The end of the fixed rod 902 is fixedly connected with a ring 903, and the ring 903 is movably sleeved on the periphery of the annular groove 807. By setting two sets of electric push rods 901, the fixed rod 902 is driven to move by the output shaft of the electric push rod 901, which drives the ring 903 connected to the fixed rod 902 to move synchronously, and the ring 903 is sleeved on the periphery of the annular groove 807, thereby driving the sleeve 806-level transfer gear 803 to slide outside the rotating shaft 801, thereby realizing the transmission and cutting off of power.

[0032] In this embodiment, a positioning hole 303 is formed through the middle of the bottom of the turntable 3, a pin shaft matched with the positioning hole 303 is fixedly connected in the middle of the top of the base 10, a gear ring 11 is fixedly connected to the top of the pin shaft, and the bottom of the gear ring 11 is slidably connected to the top of the turntable 3. The base 10 is rotatably connected to the turntable 3 through the rotational connection between the pin shaft and the positioning hole 303. When the direction angle of the receiver 1 needs to be adjusted, a group of electric push rods 901 at the bottom are controlled so that their output shafts drive the fixed rod 902 and the ring 903 fixedly connected thereto to move outward, thereby driving the sleeve 806 connected thereto and a group of transfer gears 803 at the bottom to move synchronously, so that the transfer gear 803 is meshed with the gear ring 11, and then the driving motor 701 is turned on so that the driving gear 702 drives the transmission gear 802 to rotate, thereby driving the transfer gear 803 to rotate, so that the group of transfer gears 803 at the bottom walk on the top of the gear ring 11, thereby driving the receiver 1 to rotate and adjust the direction angle.

[0033] Working principle: when in use, the device is fixed by the base 10. When the inclination angle of the receiver 1 needs to be adjusted, the electric push rod 901 at the top is started, so that the output shaft drives the fixed rod 902 and the ring 903 fixed thereto to move synchronously, thereby pushing the sleeve 806 and the transfer gear 803 to one side of the driven gear 605, so that the transfer gear 803 is meshed with the driven gear 605. Subsequently, the driving motor 701 is turned on, so that its output shaft drives the driving gear 702 to rotate, thereby driving the transmission gear 802 to rotate, driving the rotating shaft 801 and the transfer gear 803 to rotate, and a group of transfer gears 803 at the upper end are meshed with the driven gear 605, thereby driving the lead screw 601 to rotate, so that the inner screw 602 moves outside the lead screw 601, driving the connecting rod 606 to move synchronously, and through the connection action of the second pin shaft 607, the fixed bracket 2 rotates around the first pin shaft 502. , to adjust the inclination angle of the receiver 1, and then control a group of electric push rods 901 at the upper end so that its output shaft drives the fixed rod 902 and the ring 903 to reset, so that the sleeve 806 and the transfer gear 803 are reset, and the meshing with the driven gear 605 is released. When the direction angle of the receiver 1 needs to be adjusted, the group of electric push rods 901 at the bottom is controlled so that its output shaft drives the fixed rod 902 and the ring 903 fixedly connected thereto to move outward, thereby driving the sleeve 806 connected thereto and a group of transfer gears 803 at the bottom to move synchronously, so that the transfer gear 803 is meshed with the ring gear 11, and then by turning on the drive motor 701, the driving gear 702 drives the transmission gear 802 to rotate, thereby driving the transfer gear 803 to rotate, so that the group of transfer gears 803 at the bottom walks on the top of the ring gear 11, thereby driving the receiver 1 to rotate and adjusting the direction angle.
