[0052] Specifically, the adjustment rod includes a first adjustment rod 31, a second adjustment rod 32 and a third adjustment rod 33, the adjustment device includes a first adjustment device 6, a second adjustment device 7 and a third adjustment device 8, and the connecting device includes a first connecting device, a second connecting device and a third connecting device. The first adjustment rod 31, the second adjustment rod 32 and the third adjustment rod 33 are arranged parallel to each other; one end of the first adjustment rod 31 is movably connected to the middle position of the mounting bracket 1 through the first adjustment device 6, and the other end of the first adjustment rod 31 is movably connected to the middle position of the mounting seat 20 through the first connecting device; one end of the second adjustment rod 32 is movably connected to one end of the mounting bracket 1 through the second adjustment device 7, and the other end of the second adjustment rod 32 is movably connected to one end of the mounting seat 20 through the second connecting device; one end of the third adjustment rod 33 is movably connected to the other end of the mounting bracket 1 through the third adjustment device 8, and the other end of the third adjustment rod 33 is movably connected to the other end of the mounting seat 20 through the third connecting device; the second connecting device and the third connecting device are arranged perpendicular to each other.

[0053] like Figure 2-3 As shown, the mounting bracket 1 is an L-shaped bracket, consisting of a vertically arranged first connecting arm 11 and a horizontally arranged second connecting arm 12, the first connecting arm 11 and the second connecting arm 12 being fixedly connected to form an integral structure. The mounting base 20 is an L-shaped mounting base, consisting of a vertically arranged first mounting arm 21 and a horizontally arranged second mounting arm 22, the first mounting arm 21 and the second mounting arm 22 being fixedly connected to form an integral structure.

[0054] The first connecting device is a universal joint 9 , and the other end of the first adjusting rod 31 is movably connected to the connection position between the first mounting arm 21 and the second mounting arm 22 of the mounting seat 20 through the universal joint 9 .

[0055] The second connecting device includes a first connecting rod 41 and a first ball bearing 51. One end of the first connecting rod 41 is hingedly connected to the other end of the second adjustment rod 32, and the other end of the first connecting rod 41 is movably connected to one end of the mounting base 20 through the first ball bearing 51. The other end of the second adjustment rod 32 is movably connected to the free end of the first mounting arm 21 of the mounting base 20 through the second connecting device.

The other end of the third adjustment rod 33 is movably connected to the free end of the second mounting arm 22 of the mounting base 20 via the third connecting device.

[0057] like Figure 1-3 As shown, the first adjustment device 6 includes an adjustment screw 61. A first mounting hole 100 is provided through the center of the mounting bracket 1. The first mounting hole 100 matches the adjustment screw 61. The adjustment screw 61 extends from the back of the mounting bracket 1 through the first mounting hole 100 and into one end of the first adjustment rod 31. One end of the adjustment screw 61 always remains in the same plane as the back of the mounting bracket 1. A first internally threaded hole is provided inwardly at one end of the first adjustment rod 31. The first internally threaded hole matches the external thread at the other end of the adjustment screw 61. The adjustment screw 61 is screwed into the first internally threaded hole via the external thread, so that one end of the first adjustment rod 31 and the other end of the adjustment screw 61 are movably connected through threaded engagement. One end of the first adjustment rod 31 is movably connected to the connection point between the first connecting arm 11 and the second connecting arm 12 of the mounting bracket 1 via the adjustment screw 61.

[0058] The first adjusting rod 31 moves forward or backward by adjusting the adjusting screw 61 in the first adjusting device 6 , thereby pushing the platform 2 to move forward or backward.

[0059] like Figure 1-3As shown, the second adjustment device 7 includes a first adjustment column 71 and a first pin 72. A second mounting hole 110 is provided at one end of the mounting bracket 1. The second mounting hole 110 matches the first adjustment column 71. The first adjustment column 71 passes through the second mounting hole 110 from the back of the mounting bracket 1 and extends into one end of the second adjustment rod 32.

[0060] The first adjusting column 71 is provided with a first annular groove 711 on the circumference of the second mounting hole 110, and the mounting bracket 1 is provided with a first pin hole 111 at a position corresponding to the first annular groove 711. The first pin hole 111 matches the first pin 72, and the first pin 72 passes through the first pin hole 111 and extends into the first annular groove 711, limiting the movement of the first adjusting column 71 in the front-to-back direction, so that the relative position between one end of the first adjusting column 71 and the back side of the mounting bracket 1 always remains unchanged, ensuring that the first adjusting column 71 does not move in the front-to-back direction by rotating around its own axis.

[0061] The other end of the first adjusting column 71 is provided with a first external thread section 712, and one end of the second adjusting rod 32 is provided with a second internal thread hole inwardly, and the second internal thread hole matches the first external thread section 712. The first adjusting column 71 is screwed into the second internal thread hole through the first external thread section 712, so that one end of the second adjusting rod 32 is movably connected to the other end of the first adjusting column 71 through threaded cooperation.

[0062] One end of the second adjustment rod 32 is movably connected to the free end of the first connecting arm 11 of the mounting bracket 1 via a first adjustment column 71 and a first pin 72 in the second adjustment device 7. The second adjustment rod 32 is adjusted forward or backward by the first adjustment column 71 in the second adjustment device 7, thereby pushing the platform 2 to swing forward or backward about the universal joint 9.

[0063] like Figure 1-3 As shown, the third adjustment device 8 includes a second adjustment column 81 and a second pin 82, and a third mounting hole 120 is opened at the other end of the mounting bracket 1. The third mounting hole 120 matches the second adjustment column 81. The second adjustment column 81 passes through the third mounting hole 120 from the back of the mounting bracket 1 and extends into one end of the third adjustment rod 33.

[0064] The second adjusting column 81 is provided with a second annular groove 811 on the circumference located in the third mounting hole 120, and the mounting bracket 1 is provided with a second pin hole 121 at a position corresponding to the second annular groove 811. The second pin hole 121 matches the second pin 82, and the second pin 82 passes through the second pin hole 121 and extends into the second annular groove 811, limiting the movement of the second adjusting column 81 in the front-to-back direction, so that the relative position between one end of the second adjusting column 81 and the back side of the mounting bracket 1 always remains unchanged, ensuring that the second adjusting column 81 does not move in the front-to-back direction by rotating around its own axis.

[0065] The other end of the second adjusting column 81 is provided with a second external thread section 812, and one end of the third adjusting rod 33 is provided with a third internal thread hole inwardly, and the third internal thread hole matches the second external thread section 812. The second adjusting column 81 is screwed into the third internal thread hole through the second external thread section 812, so that one end of the third adjusting rod 33 and the other end of the second adjusting column 81 are movably connected through threaded cooperation.

[0066] One end of the third adjustment rod 33 is movably connected to the free end of the second connecting arm 12 of the mounting bracket 1 via a second adjustment column 81 and a second pin 82 in the third adjustment device 8. The third adjustment rod 33 is adjusted forward or backward by the second adjustment column 81 in the third adjustment device 8, thereby causing the platform 2 to swing left or right about the universal joint 9.

[0067] The working principle of a rotary regulator provided by the present invention is as follows:

[0068] When the first adjusting column 71 is rotated in a certain direction, the first external thread section 712 and the second internal thread hole form a spiral transmission that forces the second adjusting rod 32 to move horizontally backward, pushing the platform 2 to swing backward around the universal joint 9; conversely, when the first adjusting column 71 is rotated in the opposite direction, the first external thread section 712 and the second internal thread hole form a spiral transmission that forces the second adjusting rod 32 to move horizontally forward, pushing the platform 2 to swing forward around the universal joint 9.

[0069] When the second adjusting column 81 is rotated in a certain direction, the second external thread section 812 and the third internal thread hole form a spiral transmission to force the third adjusting rod 33 to move horizontally backward, thereby pushing the platform 2 to swing to the right around the universal joint 9; conversely, when the second adjusting column 81 is rotated in the opposite direction, the second external thread section 812 and the third internal thread hole form a spiral transmission to force the third adjusting rod 33 to move horizontally forward, thereby pushing the platform 2 to swing to the left around the universal joint 9.

[0070] When the distance between the platform 2 and the mounting bracket 1 needs to be adjusted, the first adjusting column 71, the second adjusting cylinder 81 and the adjusting screw 61 are rotated so that the first adjusting rod 31, the second adjusting rod 32 and the third adjusting rod 33 all move forward or backward by the same distance.

[0071] The present invention has been described in detail above with reference to the accompanying drawings and embodiments. However, the present invention is not limited to the above embodiments. Various modifications can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention. Any content not described in detail in the present invention may be adapted from existing technologies.
