Description

A kind of portable jack knife

【Technical field】

The present invention relates to jack knife technical fields, and in particular to a kind of portable jack knife.

【Background technology】

Jack knife generally comprises handle and blade, and blade can opposite handle expansion and folding.Existing jack knife is inconvenient to carry, People tend not to often take jack knife with oneself, when in use, usually due to can not find jack knife, and are brought to production or life It is inconvenient.

【Invention content】

In view of the above problems, it is necessary to which a kind of portable jack knife is provided.

In order to achieve the above objectives, the technical solution adopted in the present invention is：

A kind of portable jack knife, including：

Handle, the handle include two liners being oppositely arranged, and one end of an at least liner, which is connected with one, has opening Hook；

The root of blade, the blade is rotationally located in one of two liners far from the hook by a pivot part End；

Bottom bone, the bottom bone include a fixed part and the extension arm for being connected to described fixed part one end, the fixed part with The liner and/or hook connection, the extension arm extends towards the pivot part, and the free terminal of the extension arm It stretches between described two liners；

When the blade is in a collapsed position, the blade of the blade is located between two liners, and the blade is remote One end from the pivot part coordinates with the hook to close the opening, one end energy of the blade far from the pivot part It is enough to turn to an open position towards the extension arm in stress, to open the opening.

Further, the extension arm is elastic arm, and the root of the blade includes the first side being oppositely arranged and the Dual side-edge, close to the blade of the blade, the first side is convexly equipped with one and compresses for the first side second side Portion, the pressure section contradict the extension arm when the blade turns to the open position from the collapsed position and make institute Extension arm flexible deformation is stated, the extension arm makes the blade be reset to the collapsed position for elastic recovery.

Further, the extension arm includes interconnecting piece, rake and abutting part, and the connecting portion is in the handle Outside, the abutting part stretches between two liners, and the rake connects the interconnecting piece and the abutting part, the company Socket part is connect with the fixed part, and when the blade is in collapsed position, the pressure section connects with the abutting part.

Further, the second side is recessed with a card slot, when the blade rotation a to expanded position, the blade Outside the handle, the card slot engages with end of the extension arm far from the fixed part, to limit the blade Rotation.

Further, at least one side of the blade is concavely provided with bit-avoiding slot, to facilitate rotating blade.

Further, the one end of each liner far from the pivot part is respectively connected with the hook, the fixed part sandwiched It is fixed between the hook of two liners, and by the hook of locking piece and two liners.

Further, the quantity of the locking piece is two, and two locking pieces are located at the opposite sides of the blade.

Further, the pivot part is a connecting shaft, and the both ends of the connecting shaft are connect with two liners respectively.

Due to the adoption of the above technical scheme, the invention has the advantages that：

Above-mentioned portable jack knife be equipped with hook, in use, can by hook by jack knife hang over trousers ear, key-ring, backpack strip, On the objects such as rope, convenient for users to carrying, jack knife is taken whenever and wherever possible.When blade folding hook is closed with hook cooperation Opening, prevent jack knife from falling off from user.Meanwhile by jack knife per se with blade and hook cooperation open or The opening for closing hook can reduce parts used in jack knife, further without the stop hook of in addition setting and hook cooperation Reduce the volume of jack knife, is more convenient to carry, and the cost of jack knife can be reduced.
