[0049] Through the transmission connection between the first transmission shaft 2 and the third transmission shaft 5 and the transmission connection between the second transmission shaft 4 and the third transmission shaft 5, the force of the first transmission shaft 2 can be transmitted to the second transmission shaft 4 via the third transmission shaft 5, thereby driving the projection device 6 to rotate.

[0050] The ratio of the wheel diameters of the first pulley 7 and the second pulley 8 is equal to the ratio of the wheel diameters of the third pulley 9 and the fourth pulley 10. Preferably, the wheel diameters of the first pulley 7, the second pulley 8, the third pulley 9, and the fourth pulley 10 are the same, that is, the ratio of the wheel diameters of the first pulley 7 and the second pulley 8 is 1:1, and the ratio of the wheel diameters of the third pulley 9 and the fourth pulley 10 is also 1:1, so as to ensure the synchronous rotation of the first transmission shaft 2 and the second transmission shaft 4, thereby enabling the projection device 6 to follow the workpiece.

[0051] It also includes a turntable 11, which is arranged on the mounting plate 1 and fixedly connected to the first transmission shaft 2.

The cross section of the push rod 123 is prismatic, and more preferably, the cross section of the push rod 123 is rectangular, which can effectively prevent the push rod 123 from rotating and ensure a better locking effect.

[0053] Specifically, the cover plate 125 is fixed below the mounting plate 1, and a through slot is provided on the contact surface between the cover plate 125 and the mounting plate 1; the push rod 123 is inserted into the through slot of the cover plate 125, and slides in the through slot of the cover plate 125 in a direction away from or close to the turntable 11.

The height adjustment mechanism 13 also includes an adjustment knob 131 and an adjustment shaft 132, and the adjustment knob 131 is connected to the adjustment gear 133 via the adjustment shaft 132.

[0056] Specifically, by twisting the adjustment knob 131, the adjustment shaft 132 drives the adjustment gear 133 to rotate, so that the first rack 134 and the second rack 135 are relatively staggered, thereby changing the height of the projection device 6. Preferably, the gear and rack are self-locking. The relative height between the projection device 6 and the mounting plate 1 and the turntable 11 can be adjusted through the height adjustment mechanism 13. When workpieces of different heights are installed on the turntable and the height of the projection device 6 needs to be adjusted, the height adjustment mechanism 13 can be used to make the adjustment convenient and quick.

[0057] Please refer to Figures 1 to 3 As shown, the specific working process of the utility model is as follows: the workpiece is placed on the turntable 11, the push rod 123 is pulled out, so that the clamping head 124 is separated from the turntable 11, and the turntable 11 is rotated to rotate the workpiece to the required position; the push rod 123 is released, and the clamping head 124 is clamped with the turntable 11 under the action of the compression spring 122 to keep the turntable 11 fixed; the height of the projection device 6 and the turntable 11 is adjusted to a suitable position through the height adjustment mechanism 13; the projection device 6 projects an image onto the surface of the workpiece located on the turntable 11; when the workpiece angle needs to be adjusted again, the above actions are repeated.

[0058] The above description is only a specific embodiment of the present disclosure, so that those skilled in the art can understand or implement the present disclosure. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present disclosure.
