Summary of the invention:
At the defective that prior art exists, the purpose of this utility model provides a kind of above-mentioned defective that can overcome, the modified tapered end that can avoid unlocking tool to move repeatedly and just lockset can be opened.
The technical scheme in the invention for solving the technical problem is: a kind of modified tapered end, described tapered end comprises lock housing and lock gall, be provided with blade in the described lock gall, described lock gall center is provided with keyhole, key is that side direction is provided with a plurality of blade grooves on the described lock gall, described blade is placed in the blade groove, described blade center is provided with the endoporus that adapts to key shape, the inner hole wall of described blade is provided with and promotes projection, outer wall at described blade is provided with a locking slot, the axis direction of described lock gall is provided with the excellent groove of a lock, can place a locking rod in the excellent groove of described lock, described lock-shell lining is provided with lock slots, and the side of described endoporus is provided with a spring screens, and the spring screens is used for being connected with spring.
The groove that described blade groove communicates about being, be provided with two blades in described each blade groove, described blade is provided with in the relative direction, described promotion projection is arranged on the end face of the inner hole wall of blade, described locking slot is arranged on the top of blade groove, and the corresponding top that promotes projection that is arranged on, the promotion projection set-point in the described lock gall on a plurality of blades in the same way is not in same position.
Be provided with the jack-up spring in the described lock slots, be used for locking rod is pushed into lock gall, make the lock gall in the lock housing not rotatable.
The blade groove of side direction setting is four to six on the described lock gall.
The blade of modified tapered end of the present utility model adopts the mode of Sliding Control, the combination of the diverse location of locking slot on the blade and promotion projection, make the combinations of the many group blades multiple lockset position of coupler of can arranging in pairs or groups out, improved that to have a pick-proof good, make lockset have advantage safe in utilization.
