The fan fixing apparatus includes a plurality of mushroom pillars and a frame. The mushroom pillars are disposed on the casing, and the frame has a clamping portion for clamping the fan and a plurality of gourd holes corresponding to the mushroom pillars. The gourd hole has a guiding portion, a positioning portion and a slide rail communicating the guiding portion and the positioning portion. The mushroom pillar is inserted into the guiding portion, and is finally positioned in the positioning hole by moving along the slide rail, such that the fan fixing apparatus is rapidly positioned in the casing.

Abstract: A plug fastening device applied to a socket-forming side having a first fixing portion is provided. The plug fastening device includes a fixing member and a binding member. The fixing member has at least one first coupling portion, and a second fixing portion for being fixed to the first fixing portion. The binding member is capable of binding an end of a plug, and has at least one second coupling portion for being coupled to the first coupling portion. As the binding member is applicable to all kinds of plugs with different specifications, the drawback in the prior art that the conventional plug fastening device cannot be universally used is overcome.
