Abstract
The utility model provides an unlocking automatic blade push-off mechanism, which is arranged on a tool bit seat and comprises a clamping position wheel claw and a torsion spring. The clamping position wheel claw movably installed on the tool bit seat can rotate, and the torsion spring arranged between the lower end of the clamping position wheel claw and the tool bit seat provides elasticity for the clamping position wheel claw. The unlocking automatic blade push-off mechanism is extremely convenient and rapid in operation when blades are replaced, and is simple in structure and low in manufacturing cost.
Description
Technical field
The utility model relates to a kind of hand-held tool, and blade mechanisms is released in the release that relates in particular to a kind of cutting knife automatically.
Background technology
Traditional cutting knife often is divided into fixed, collapsible and telescopic, generally is used for cutting paper, cloth, leather etc.During traditional cutting knife blade release is that blade maintains static, and need pinch taking-up with two fingers.Prior art has the method for multiple different replacing blade, and when various replacing methods all were the blade release, blade maintained static, because the extension of blade is shorter, so the area of finger contactor blade is less when getting blade, operation inconvenience also easily scratches sometimes.
The utility model content
The purpose of this utility model is exactly in order to provide a kind of release that can convenient and swift replacing blade to release blade mechanisms automatically.
In order to achieve the above object, the utility model has adopted following technical scheme: blade mechanisms is released in a kind of release automatically, be arranged on the tool tip, comprise screens tire and torsion spring, the screens tire is movably arranged on the tool tip rotatable, and torsion spring is arranged between the lower end of screens tire and the tool tip and provides elastic force to the screens tire.
Described screens tire comprises rotating disk and the claw that fuses, claw can insert the interior groove realization release that forms locking or withdraw from blade of intrinsic groove of blade, the inboard of rotating disk is connected with one and is used for and rotatable central shaft and the eccentric rod that is used to locate torsion spring that links to each other of tool tip, and the outer lower portion of rotating disk is provided with one and is used for the concave station of ccontaining blade and forms one at the rear portion being used for the incline bench that blade is extrapolated.
Be provided with the die cavity that is used for ccontaining screens tire and torsion spring in the described tool tip, this die cavity comprises the axis hole of the central shaft that is used to install the screens tire and is used to locate the circular groove of torsion spring, and the lower end of torsion spring is inlaid in this circular groove.
The lower inside of described rotating disk is provided with a concave station, forms an arc step between this concave station upper end and the turntable body; Described eccentric rod is arranged on this concave station; The upper end of described torsion spring is stuck between above-mentioned arc step and the eccentric rod.
The utility model release is released blade mechanisms automatically owing to adopted above technical scheme, makes it compared with prior art, has following advantage and characteristics:
1, the locking and unlocking is simple to operate, replacing blade that can be very convenient, fast.
2, low production cost is easy to large-scale popularization.

The specific embodiment
Referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4, blade mechanisms is released in release of the present utility model automatically, be installed on the tool tip 1, in tool tip 1, be provided with blade 2, at blade 2 upper covers tool tip cover plate 3 is arranged, release is released blade mechanisms automatically and is comprised screens tire 4 and torsion spring 5, and screens tire 4 is movably arranged on the tool tip 1 rotatable, and torsion spring 5 is arranged between the lower end of screens tire 4 and the tool tip 1 and provides elastic force to the screens tire.
Be provided with the die cavity 11 that is used for ccontaining screens tire 4 and torsion spring 5 in the tool tip 1 in the utility model, this die cavity comprises the axis hole 12 of the central shaft that is used to install the screens tire and is used to locate the circular groove 13 of torsion spring, and the lower end of torsion spring 5 is inlaid in this circular groove 13.
The unlocking condition that blade mechanisms is released in the utility model release automatically as shown in Figure 6, in the time of need unblanking, with the rotate backward rotating disk 41 of screens tire 4 of finger, thereby driving claw 42 moves up, withdraw from the groove 21 of blade 2 gradually, when rotating disk 41 turned to certain angle, the incline bench 46 in the rotating disk outside was with the extrapolated segment distance of blade, blade 2 promptly is in released state, can pull out the replacing blade easily forward.When unclamping rotating disk 41, screens tire 4 promptly recovers lock-out state under the elastic force effect of torsion spring 5, as shown in Figure 5.As seen, release of the present utility model is released blade mechanisms automatically when changing blade, operates extremely convenient and swift.
