Two support rods 8 are fixed to the upper surface of the base plate 13 by bolts. A fixing frame 5 is fixed to the top between the two support rods 8 by bolts. A slide groove 3 is opened inside the fixing frame 5. Two slides 15 are slidably connected in the slide groove 3. A bidirectional threaded rod 2 is rotatably connected in the slide groove 3, and the bidirectional threaded rod 2 is threadedly connected to the slide 15. A first motor is fixed to the top of one of the support rods 8 by bolts, and one end of the first motor output shaft is fixed to the bidirectional threaded rod 2. The top and bottom of the connecting frame 6 are rotatably connected to the connecting rod 7, and the connecting rod 7 is rotatably connected to the support frame 4. A second motor is fixed to one side of the support frame 4 by bolts, and a fixing frame is fixed to one side of the support frame 4 by bolts. 5. One end of the second motor output shaft passes through the fixing frame 5 and is fixed with a shell 17 by bolts. The top of the shell 17 is rotatably connected to the working plate 1. A plurality of connecting holes are provided inside the working plate 1. The rotation of the first motor causes the bidirectional threaded rod 2 to drive the slide 15 to move toward the middle along the slide groove 3, so that the connecting rod 7 pushes the support frame 4 to move, and thereby the horizontal position of the working plate 1 is adjusted. The bottom inner wall of the shell 17 is fixed with a third motor by bolts, and one end of the third motor output shaft is fixed to the working plate 1. Start the second motor, and the second motor rotates to rotate the shell 17, so that the angle of the workpiece on the working plate 1 is adjusted. Start the third motor, and the third motor drives the working plate 1 to rotate, so that the workpiece on the working plate 1 rotates, so that the workpiece can be adjusted at multiple angles.

[0023] In the present invention, it should be noted that the bottom of the support frame 4 is fixed with two support plates 11 by bolts, and the bottom of the working plate 1 is fixed with two guide rods 18 by bolts, and the support plate 11 is slidably connected to the guide rods 18, and the guide rods 18 can guide the support plate 11 so that the support plate 11 can move stably to avoid the support frame 4 from tilting during the movement. The bottom between the two support plates 11 is rotatably connected to the first roller 12, and the first roller 12 is in contact with the bottom plate 13. Both sides of the slide 15 are rotatably connected to two second rollers 16, and the second roller 16 is in contact with the connecting frame 6, and the support frame 4 moves The support plate 11 drives the first roller 12 to move on the base plate 13, so that the support frame 4 can move more smoothly while being supported. Two threaded holes are provided inside the base plate 13, and the two threaded holes are threadedly connected with a first threaded rod 9. The bottom end of the first threaded rod 9 is provided with a protective pad 10. After moving the device to the required position, the first threaded rod 9 is rotated to move the protective pad 10 downward until the protective pad 10 is in close contact with the ground or platform, thereby assisting in fixing the position of the device to prevent the device from being easily displaced. A plurality of universal wheels 14 are fixed to the bottom of the base plate 13 by bolts, which is convenient for the staff to push the device to move.

[0024] Working principle: When the position of the working plate 1 needs to be adjusted horizontally, the first motor is started, and the rotation of the first motor causes the bidirectional threaded rod 2 to drive the slide 15 to move toward the middle along the slide groove 3, so that the connecting rod 7 pushes the support frame 4 to move, and then the horizontal position of the working plate 1 is adjusted. When the angle of the working plate 1 needs to be adjusted, the second motor is started, and the rotation of the second motor causes the shell 17 to rotate, and then the angle of the workpiece on the working plate 1 is adjusted. The third motor is started, and the third motor drives the working plate 1 to rotate, so that the workpiece on the working plate 1 rotates, and then the workpiece is adjusted at multiple angles.
