Abstract

The utility model relates to a manual cutter mechanism, in particular to an opening and closing cutter mechanism of a rotating shaft, which comprises a cutter handle A and a cutter handle B, wherein a cutter head is hinged between the cutter handle A and the cutter handle B through an opening and closing shaft; the top end of the cutter handle A is provided with a through hole for the opening and closing shaft to pass through, and the top end of the cutter handle B is provided with a groove for the opening and closing shaft to abut; a spring is arranged between the opening and closing shaft and the groove; an opening position locking slot and a closing position locking slot are arranged in the cutter head; and the opening position locking slot and the closing position locking slot are matched with an opening position locking lug and a closing position locking lug on the opening and closing shaft. Compared with the prior art, the opening and closing cutter mechanism of the rotating shaft has the advantages of reasonable design, simple structure, fewer parts, low cost, convenience in use, safety, and reliability, and the like.

Description

A kind of rotating shaft folding cutter mechanism

Technical field

The utility model relates to a kind of hand knife mechanism, specifically provides a kind of rotating shaft folding cutter mechanism.

Background technology

Existing folding hand knife is mainly back of the body lock and two kinds of mechanisms of limit lock, and it is realized the locking of hand knife through snap close or spring steel plate and opens, the structure relative complex, and not only part is many, and cost of manufacture is high, and use is convenient inadequately.

Summary of the invention

The utility model is to above problem, and a kind of rotating shaft folding cutter mechanism is provided, and starts with at cutter head and handle of a knife connecting axle place, gives up the snap close of back of the body lock and the spring steel plate of limit lock, has reduced production cost and has realized operability easily.

The utility model solves the technical scheme that its technical problem adopted:

A kind of rotating shaft folding cutter mechanism; Comprise handle of a knife A and handle of a knife B; Be hinged with cutter head through switch shaft between said handle of a knife A and the handle of a knife B; Handle of a knife A top is provided with the through hole that supplies described switch shaft to pass, and said handle of a knife B top is provided with and supplies described switch shaft against the groove of living, and is provided with spring between described switch shaft and the groove; Be provided with out a lock slots in the said cutter head and close a lock slots, saidly open a lock slots, close opening a latch ear and closing a latch ear on a lock slots and the described switch shaft and cooperate.

Described switch shaft comprises axis body; A side is provided with out a latch ear on the described axis body; Be provided with a stair-stepping latch ear of closing with the said relative axis body opposite side of a latch ear of opening, described axis body bottom is provided with blind hole, and said blind hole is used for the described spring of device.

Opening a lock slots is triangle, quadrangle or profile of tooth with closing a lock slots.

A kind of rotating shaft folding cutter mechanism of the utility model, handle A and handle B are having manhole and groove with the cutter head junction; Cutter head C end is provided with circular hole, and there is square groove inside; Axle is cylindric two sideband side's ear shape structures, and blind hole is arranged at the bottom, and spring is housed in the blind hole.

Cutter head cooperates with handle of a knife through axle, realizes that cutter head rotates; Be provided with square groove in handle of a knife B and the handle of a knife A, cooperate with latch ear on the axle and realize position of the switch locking.

Shaft head passes the through hole of handle of a knife A, supplies finger presses.

Realize the action of function: assembling is pressed lower shaft after accomplishing, and cutter head can arbitrarily sway; Unclamp finger in the fully open position, cutter head can lock herein, can normally use cutter safely; Finger is unclamped at the place in closure, and cutter head can lock herein, can locked safely cutter head, prevent that to a greater extent accident from opening, and prevent unexpected injury.

What cutter head was inner opens a lock slots and closes a lock slots like more shallow or other shape of design, can realize slight lock knife head status, can slightly firmly can open cutter head.According to user's use habit, two kinds of structures all can adopt; The latch ear of lock slots that cutter head is inner or axle be shaped as triangle, quadrangle or polygon or profile of tooth all can realize above-mentioned functions, wherein adopt profile of tooth, cutter head can stop and locking the optional position in slewing area.

Compared with prior art, a kind of rotating shaft folding cutter mechanism of the utility model, it has advantages such as reasonable in design, simple in structure, that the few cost of part is low, esy to use, safe and reliable.
