For achieving the above object, the utility model provides following technical scheme: a kind of fuse, comprise shell, on the base of described shell, be provided with fixation kit, described fixation kit includes fixed tab and deck, between described fixed tab and shell, be formed with breach, on described deck, be provided with mobile wing and STATEMENT OF FEDERALLY SPONSORED, between described fixed tab and mobile wing, be provided with the positioning chamber for guide rails assembling, described mobile wing includes abutting part and the movable part being connected with deck, described movable part is set to gear and described movable part axial restraint rotates in a circumferential direction, described STATEMENT OF FEDERALLY SPONSORED includes operating portion and is positioned at the tooth bar of operating portion opposite side, described tooth bar is meshed with movable part and described operating portion extends to outside deck, in described deck, be provided with the chute for STATEMENT OF FEDERALLY SPONSORED slippage, described STATEMENT OF FEDERALLY SPONSORED is arranged in chute and can be along chute setting party to moving back and forth, between described fixed tab and case surface, be formed with breach and described location division can be embedded in breach, described abutting part can circumferentially turn in positioning chamber with movable part.
By adopting technique scheme, pull operation portion just can drive rack and pinion to rotate, because movable part moves in the circumferential direction, so when pulling out operating portion, the rotation of movable part can drive the abutting part base motion of fuse shell dorsad, be that abutting part can be opened positioning chamber, now fuse is inserted in guide rail, when then inwardly promoting operating portion, abutting part just can be closed positioning chamber again, mutually conflict to realize with guide rail and fix, this matching relationship by rack-and-pinion is realized the installation of fuse and guide rail, cancel the fixing means that original employing back-moving spring utilizes spring energy storage, solve the problem that causes fixed effect to decline because of back-moving spring elastic fatigue, and the mode of operation of rack-and-pinion is also laborsaving accordingly, optimized the fixed structure of fuse comprehensively.
The utility model is further set to: between described operating portion and tooth bar, be articulated and connected, on described side wall of outer shell, be provided with storage tank in STATEMENT OF FEDERALLY SPONSORED position, the hinged end of described operating portion and tooth bar is positioned at one end of storage tank and the other end of storage tank is provided with elastic card claw.
By adopting technique scheme, when control operation portion makes abutting part and guide rail butt, described operating portion can rotate towards storage tank around hinged end, positioning action by elastic card claw is fixed operating portion, prevent that operating portion from resetting, the fixed effect while ensureing abutting part and guide rail butt with this.
The utility model is further set to: described operating portion hollow out is formed with finger groove.
By adopting technique scheme, operating portion hollow out is formed with finger groove, by this design that refers to groove, can easily STATEMENT OF FEDERALLY SPONSORED be extracted in chute.
