Abstract
The utility model relates to a steel ball-locked folding cutter, comprising a blade, clamp plates and a handle, wherein the clamp plate I and the clamp plate II are arranged outside the blade; a locking hole I and a locking hole II are arranged on the blade; the clamp plate I and the clamp plate II are respectively provided with a shaft hole and a spring piece; and a steel ball is pressed by the spring to piece to be clamped in the locking hole I or the locking hole II. Compared with the prior art, the steel ball-locked folding cutter has the advantages of being simple to design, produce and assemble, being reliable to use, and the like.
Description
Technical field:
The utility model belongs to cutter, especially a kind of steel ball locking jackknife tool.
Background technology:
Existing collapsible folding jack knife has a handle of a knife and can supply people to grip; Blade or other instruments have been taken in the handle of a knife the inside; Blade and handle of a knife for being connected, are provided with a back of the body spring with rotating shaft between the spine of handle of a knife, blade with carry on the back the arc surface that spring contacts and be designed to disc cam.When blade is drawn back; Protruding arc surface will be carried on the back spring jack-up; Behind the peak of the cam contact-making surface through back of the body spring, back of the body spring force discharges and blade is continued push-jump, contacts with the stop surface of carrying on the back spring up to the stop surface of blade; At this moment, blade receives pressure and the thrust of stop surface of back of the body spring and the active force of three directions that rotating shaft is the center of circle locks.When blade is closed, blade and the opposite motion process of back of the body spring experience, when arriving the closed position, blade receives the pressure of carrying on the back spring contacts back of the body spring with stop surface thrust, pins blade.
Above-mentioned jack knife though be widely used on the jack knife, like Swiss Army Knife, because still there are some weakness in structure, so that can't reach best practical function.1. it exists carries on the back spring and takies the handle of a knife space, needs to adopt big handle of a knife and thin blade usually, and in order to dodge back of the body spring position, jack knife structure and configuration design meeting are very limited; 2. design of the cam contour of blade and processing difficulties in the process of punching press and milling, cause waste because of misoperation easily; Blade collides with back of the body spring easily when 3. closing, and accelerates the passivation of blade.
Summary of the invention:
The purpose of the utility model is to overcome the problem of above-mentioned existence, and a kind of jack knife is provided, and it can improve practicality and security greatly, and has the design of being prone to, and is prone to the steel ball locking jackknife tool of producing.
The technical solution scheme of the utility model is such; A kind of steel ball locking jackknife tool comprises blade, clamping plate, handle, it is characterized in that described blade installs clamping plate I, clamping plate II outward; Described blade is provided with lock hole I; Lock hole II, described clamping plate I, clamping plate II are respectively arranged with axis hole and spring leaf, and spring leaf compresses steel ball card and goes into lock hole I or lock hole II; Described handle, clamping plate I, blade, clamping plate II correspondence are provided with axis hole and stop bit nail hole, pass axis hole with the axle nail, pass stop bit nail hole with the stop bit nail; Lock hole I, the lock hole II on described blade two sides are set to the through hole type; Lock hole I, the lock hole II on described blade two sides are set to the recess type; Described blade two sides or single face are provided with lock hole I, lock hole II, and its lock hole I, lock hole II are set to circular hole or flat hole.
Advantages such as the utility model compared with prior art has the design of being prone to, and is prone to produce, and is prone to assembling, and is safe and reliable.
