Description
[ technical field ] A method for producing a semiconductor device
The invention relates to a quick-release device for a slide rail and a wire arranging frame, and relates to the related technical field of quick-release devices for quickly combining or separating the slide rail and the wire arranging frame.
[ background of the invention ]
In the prior art, for example, in taiwan patent No. I446665 of connection device for wire rack and slide rail, a quick release device is disclosed, and a stop end of an insertion member is blocked by a block of an elastic arm to achieve the purpose of quickly assembling a wire rack and a slide rail (please refer to fig. 6 of taiwan patent No. I446665), but the following disadvantages still exist although the advantages of non-directional operation and thin design are found:
1. the first wire arranging arm and the second wire arranging arm of the wire arranging frame are movably connected and do non-linear opening and closing stretching movement along the front and back directions of the inner rail and the outer rail of the slide rail, so that the insertion piece can be separated possibly, and the wire arranging frame is liable to fall off to influence the safety.
2. When a user wants to press and apply force to make the resisting block of the elastic arm separate from the resisting end of the inserting piece, the pressing and applying force is difficult to control, and if the pressing force is small, the resisting block cannot completely separate from the resisting end, so that the user usually needs to press and apply great force to determine that the resisting block of the elastic arm completely separates from the resisting end of the inserting piece, therefore, the elastic arm is easy to deform or damage after long-time use, which further causes inaccurate resisting action, and further has the worry that the wire arranging frame falls off to influence the safety.
