Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1-3, the present utility model provides a technical solution: the utility model provides a prevent bad PCB board of photocuring processing, includes plate body 1, the top of plate body 1 is provided with chip board 3, be provided with mounting groove 2 on the lateral wall of plate body 1, fixed mounting has guide rail 5 on the inner wall of mounting groove 2, slidable mounting has extension subassembly 6 on the guide rail 5, extension subassembly 6 includes extension board 62, spout and guide rail 5 sliding connection that sets up on the lateral wall of extension board 62, fixed mounting has first magnetic path 61 on the outer wall of one side of extension board 62, the bottom slidable mounting of plate body 1 has bottom stay subassembly 7, bottom stay subassembly 7 includes slide shaft 72 and backup pad 73, the inside at plate body 1 is vertically fixed to slide shaft 72, the outside slidable mounting of slide shaft 72 has backup pad 73, the outside of slide shaft 72 is provided with outer spring 71, equal fixed mounting has second magnetic path 74 on the outer wall of both sides of backup pad 73, second magnetic path 74 is the same with the magnetic pole of first magnetic path 61.
