Description

The pintle hook lock jackknife

The utility model relates to a kind of folding cutter, and folding cutter has the pintle hook lock structure, is opening or when folding, the folding cutter that blade is blocked or locks is being arranged.

Existing pintle hook lock jackknife, have hilt, with the hinged blade of hilt.Blade is blocked or locks and keeping corresponding state, folding cutter to have the pintle hook lock structure in order to open or when folding, to have, generally all is to have bayonet socket at the blade heel, and the corresponding position of hilt has bayonet lock and disengage button.When opening or when folding, corresponding bayonet lock snaps in bayonet socket, blade is blocked or locks, when changing state, needs then to press disengage button, move blade again.Control the hand of hilt like this and pressing contact button, moving blade then often needs the another hand, and two hands need interoperation, operates relatively bothersome.When the another hand when the thing of doing other or inconvenience are used, have only blade touched folding closing on object, this damages object easily and scratches and control the hand of hilt, and the action of opening blade almost is impossible.

The purpose of this utility model provides a kind of pintle hook lock jackknife that can singlehanded open or close folding blade.

Pintle hook lock jackknife of the present utility model, still have hilt, with the hinged blade of hilt, the end of the hinged place of hilt is a circular arc, it is characterized in that: the beginning or end of hilt circular arc has the spill bayonet socket, blade folding process and circular arc and spill bayonet socket corresponding position have a chute, chute has pin corresponding with circular arc and spill bayonet socket and that can stir, is connected with the spring of pin to circular arc and spill bayonet-action between pin and the blade.Like this, directly open or folding when closing blade when folding, pin snaps in corresponding spill bayonet socket under the effect of spring, blade is fixed on the state that opens or closes.Close or roll over when directly opening blade when needs are folding, as long as overcome the resistance of spring with the finger of controlling hilt, pushing pin leaves the spill bayonet socket, simultaneously by stir pin drive blade around jointed shaft rotate, pin slides along the circular arc of hilt, and close or roll over directly and open blade is folding.Roll over the steadiness of straight open mode in order to increase blade, pin preferably also is fixed with kelly, and the hilt correspondence is provided with bayonet lock, and blades open, pin are when snapping in the spill bayonet socket, and kelly is stuck in bayonet lock, plays the effect of dual pintle hook lock.Spring and pin interactively also can adopt the indirect effect by kelly like this, and spring can be connected with pin by the kelly of pin.

The utility model compared with the prior art thus, have when one hand is pressed releasing lock card state, stir that pin drives blade rotation and folding close or roll over directly open, that has simplified blade foldingly closes or rolls over the process of directly opening, and has made things convenient for the use of pintle hook lock jackknife; Kelly that increases and corresponding bayonet lock have increased the locking steadiness of blades open state.

Accompanying drawing has been represented the folding one group of structural representation closing or roll over straight opening procedure of the folding pocket knife of a kind of pintle hook lock of the utility model.Wherein, Fig. 1 rolls over the structural representation of straight open mode for the folding pocket knife of this pintle hook lock, Fig. 2 begins the folding structural representation of straight process status of maybe will rolling over for the folding pocket knife of the folding pocket knife of this pintle hook lock, Fig. 3 is for the folding pocket knife of this pintle hook lock folding later stage of folding pocket knife or begin to roll over the structural representation of straight process status, and Fig. 4 is the structural representation of the folding closed condition of the folding pocket knife of this pintle hook lock.

Example below in conjunction with accompanying drawing further specifies the utility model.This pintle hook lock folds pocket knife, hilt 7 is arranged, pass through bearing pin 11 and the hinged blade 1 of hilt.The end of the hinged place of hilt is a circular arc 8, and the starting point 9 of hilt circular arc or terminal point 12 are the spill bayonet socket.Blade has a chute 2, and is when chute rotates with blade is folding, corresponding with the circular arc and the spill bayonet socket of hilt respectively.Have pin 3 corresponding with circular arc and spill bayonet socket and that can stir in the chute.The pin stretch out chute and with the corresponding contact of circular arc and spill bayonet socket, give prominence to outside hilt the upper end of pin, available finger is stirred or is touched.Sell 3 crosswise fixed and be connected with kelly 4, the hilt corresponding position is provided with bayonet lock 5.The arc spring 10 that one end is connected with the blade root by with being connected of kelly, and be connected with pin indirectly.Spring makes pin to circular arc and spill bayonet-action.Spring also makes the kelly card to bayonet lock.Blades open is rolled over when straight, and pin 3 snaps in spill bayonet socket 9, and an end 6 of kelly is stuck in bayonet lock 5, and blade is pinned (referring to Fig. 1).When will folding when closing blade, as long as overcome the resistance of spring with the finger of controlling hilt, pushing pin 3 leaves spill bayonet socket 9, drives kelly 4 and leaves bayonet lock 5.Simultaneously, finger is exerted oneself along circular arc, rotates, sells along the circular arc of hilt and slide (referring to Fig. 2,3) around jointed shaft by stirring pin 3 drive blades 1, with folding close (referring to the Fig. 4) of blade rotation.After folding the closing, pin 3 snaps in the spill bayonet socket 12 of circular arc terminal point under the effect of spring, blade is fixed on closing state.When will rolling over when directly opening blade, as long as overcome the resistance of spring with the finger of controlling hilt, pushing pin 3 leaves spill bayonet socket 12.Simultaneously, finger is exerted oneself along circular arc, rotates, sells along the circular arc of hilt and slide (referring to Fig. 3,2) around jointed shaft by stirring pin 3 drive blades 1, and the blade rotation folding is directly opened (referring to Fig. 4), drives kelly 4 simultaneously and is inserted in bayonet lock 5.After folding was directly opened, pin 3 snapped in the spill bayonet socket 9 of circular arc starting point under the effect of spring, and kelly 4 is stuck in bayonet lock 5, blade is fixed on the state of opening.
