[0046] When the posture of the projection module needs to be adjusted: if the projection module needs to be rotated to a position perpendicular to the electronic clock module, the piston rod of the electric cylinder 106 is controlled to retract through the first control button group, and the piston rod of the electric cylinder 106 drives the pin to move out of the limiting hole 308, and the projector housing 301 and the projector cover 302 are rotated to drive the connecting half ring 1 303 and the connecting half ring 2 304 to rotate in the rotating groove, so that the arc track half ring 307 rotates in the slot, and when the sensor 2 306 on one side of the induction block 2 305 rotates to the position corresponding to the induction block 1 107, the sensor 2 306 sends a signal, indicating that the projector housing 301 and the projector cover 302 are rotated in place, and the piston rod of the electric cylinder 106 drives the pin to be inserted into the corresponding limiting hole 308, so as to realize the fixed limit of the projection module, and the posture adjustment of the projection module in multiple directions is realized by rotating the projector housing 301 and the projector cover 302 in different directions.

[0047] If the projection module needs to be rotated to a position horizontal with the electronic clock module, when the sensor 2 306 at the lower part of the induction block 2 305 is rotated to a position corresponding to the sensor 1 108, the sensor 2 306 sends a signal, indicating that the projector housing 301 and the projector cover 302 are rotated into place (the principle of rotation is referred to above), and the piston rod of the electric cylinder 106 drives the pin to be inserted into the corresponding limiting hole 308 to achieve fixed positioning of the projection module, so that the projection module and the electronic clock module are kept horizontal, thereby achieving the posture adjustment of the projection module, and then the projection module can be adjusted in multiple directions such as horizontal and vertical directions, which not only improves the flexibility of projection, but also can limit and fix the projection module after adjustment, ensuring stability and greatly improving the scope of application.

[0048] When the projection module needs to be zoomed: before adjusting the focal length, set the parameters of the micro motor 407 in advance according to the distance to be adjusted; make the micro motor 407 work through the third control button group, the output shaft of the micro motor 407 drives the gear ring 409 to rotate through the gear 408, the gear ring 409 drives the zoom barrel 1 405 to rotate, when the zoom barrel 1 405 rotates, the zoom adjustment pin 414 is driven to slide in the zoom track groove 412 and the slide groove 1 419 through the zoom track groove 412, the zoom adjustment pin 414 drives the support ring 2 417 to slide in the slide groove 2 420, thereby driving the second lens assembly 418 to move, and then changing the distance between the second lens assembly 418 and the first lens assembly 413, so as to adjust the focal length of the projection module, and then facilitate the adjustment of the focal length of the projection module to meet the needs of different projections, greatly improving the projection effect and the user's viewing experience.

[0049] When the projection module needs to be focused: turn the focus wheel 403. When the focus wheel 403 rotates, the screw 411 is driven to rotate through the rotating ring 404. When the screw 411 rotates, it drives the support shell 1 401 to slide in the projector housing 301. The support shell 1 401 drives the support shell 2 402 to slide in the projector housing 301. The support shell 2 402 drives the projection lens assembly to slide in the projector housing 301, thereby adjusting the distance from the projection lens assembly to the imaging display surface, and then focusing is performed to ensure that the image on the display surface is clear, so that manual focusing can be performed to ensure the clarity of the projected image, improve the projection effect, and increase the user experience. At the same time, the adjustment is very convenient and quick, and there is no need for too many complicated operations.
