[0025] During implementation, the electric push plate 301 is controlled to work so that the electric push plate 301 moves to a surface away from the rotating plate. The rotating plate, without the support of the electric push plate 301, hangs on the surface of the plate body 105. At this time, the aluminum template falls into the interior of the aggregate frame 3031. The aggregate frame 3031 is supported by the support frame 106. The aluminum template is protected by the silicone pad 3032 inside the aggregate frame 3031. If it is necessary to process the aluminum template inside the aggregate frame 3031, at this time, loosen the nail body 3033, and then pull the aggregate frame 3031 to make the aggregate frame 3031 slide on the surface of the support plate 3034, thereby removing the aggregate frame 3031 and processing the aluminum template inside the aggregate frame 3031 to realize the function of the fixing device to quickly remove the processed aluminum template.
[0026] Furthermore, if Figure 2As shown, the surface of the frame 1 and the pull plate 102 are both provided with a flip mechanism 2, and the flip mechanism 2 is composed of a driving motor 201, a containing frame 202 and a flip part 203, and the flip part 203 is composed of a driven gear 2031, a rotating rod 2032 and a driving gear 2033.

[0028] Working principle: When in use, first place the frame 1 at the designated position, and place the aluminum template to be processed between adjacent plates 105. At this time, operate the control button 101 to control the electric push rod 103 to work, and adjust the distance between the plates 105 according to the diameter of the aluminum template, so that the plates 105 move to touch the side of the aluminum template respectively. Then, loosen the fastening screw 4033, and according to the thickness of the aluminum template, pull the slider 401 upward again, so that the slider 401 drives the fixing rod 402 to move. At this time, the fixing rod 402 drives the slider 401 to slide inside the adjustment groove 4032, thereby adjusting the distance between the plate 105 and the adjustment plate 104, so that the adjustment plate 104 moves to touch the surface at the top position of the aluminum template, and then tighten the fastening screw 4033 to fix the aluminum template, so as to realize the function of the fixing device to clamp and fix aluminum templates of different thicknesses, thereby expanding the scope of use of the fixing device.
[0029] Subsequently, the aluminum template is clamped under the action of the clamping mechanism 5, so that the aluminum template is better stabilized when fixed, and then the control button 101 is operated to control the driving motor 201 inside the containing frame 202 to work, and the driving motor 201 drives the rotating rod 2032 to rotate, thereby driving the driving gear 2033 to rotate, and the driven gear 2031 is driven to rotate under the meshing action of the driving gear 2033 and the driven gear 2031, thereby driving the connecting column to rotate. When the connecting column rotates, the connecting column drives the electric push rod 103 to rotate, thereby driving the aluminum template on the surface of the plate body 105 and the adjusting plate 104 to flip, and the other surfaces of the aluminum template are processed to realize the function of the fixing device to facilitate the flipping of the aluminum template, thereby making it more convenient to process the aluminum template when the fixing device is used, and at the same time, greatly improving the practicality of the fixing device when used.
[0030] The processed aluminum template needs to be removed manually, which increases the labor intensity when the fixing device is used. The electric push plate 301 in a normal state is fixed to the bottom of the plate body 105 by fastening the studs 302 to support the rotating plate on the surface of the plate body 105. If the aluminum template needs to be removed, at this time, the control button 101 is operated to control the electric push plate 301 to work, so that the electric push plate 301 moves to the surface away from the rotating plate. The rotating plate is not supported by the electric push plate 301 and falls on the surface of the plate body 105. At this time, the aluminum template falls into the inside of the aggregate frame 3031 and is held by the support frame 106. The aggregate frame 3031 is supported under the action of the silicone pad 3032 inside the aggregate frame 3031, and the aluminum template is protected. If the aluminum template inside the aggregate frame 3031 needs to be processed, at this time, loosen the nail body 3033, and then pull the aggregate frame 3031 to make the aggregate frame 3031 slide on the surface of the support plate 3034, so that the aggregate frame 3031 is removed, and the aluminum template inside the aggregate frame 3031 is processed to realize the function of the fixing device to quickly remove the processed aluminum template, thereby improving the working efficiency when the fixing device is used, and finally completing the use of the fixing device.
