Description

Butterfly knife blade replacing structure

Technical Field

The utility model relates to a butterfly knife technical field specifically is a butterfly knife blade replacement structure.

Background

A butterfly knife is an atypical clasp that completely eliminates the need for a sheath. The novel knife handle can be conveniently and safely retracted to be half of the length, the knife handle has double functions, and not only is a sheath, but also can be rotated to form a firm handle. A butterfly knife is an improvement over a typical clasp knife because it can be opened with one hand. In addition, the protruding handle may provide protection against the hand slipping onto the blade tip. The blade of the traditional butterfly knife is directly and rotatably connected with the knife handle through the rotating shaft, and the blade is difficult to take down from the knife handle.

Therefore, a butterfly knife blade replacing structure is provided to solve the above problems.

An object of the utility model is to provide a butterfly knife blade replacement structure to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a butterfly knife blade replacement structure, includes blade hosel, blade, first handle of a knife and second handle of a knife, the one end of blade is pegged graft in the blade hosel, and the afterbody of blade is equipped with concave position draw-in groove, first handle of a knife and second handle of a knife symmetry set up in blade hosel both sides, and the one end of first handle of a knife and second handle of a knife all rotates through pivot and blade hosel to be connected, one side of blade hosel is equipped with the opening, and is equipped with the slider in the opening, the one end and the blade hosel of slider are connected, and the other end and the blade hosel joint of slider, the inboard of slider is equipped with fixed protruding muscle.

According to the blade scabbard fixing device, the blade scabbard is arranged between the blade and the handle, the handle is rotatably connected with the blade scabbard through the rotating shaft, a slot for fixing the blade is further formed in the blade scabbard, a concave clamping groove is formed in one side of the blade, a sliding block is arranged on one side of the blade scabbard, one end of the sliding block is in pin connection with the blade scabbard, the other end of the sliding block is in clamping connection with the blade scabbard, and a limiting convex rib matched with the concave clamping groove of the blade is arranged on one side of the sliding block, so that the blade can be fixed on the blade scab.

Preferably, the opening is provided with a clamping portion.

The end of the clamping part, which is provided with the sliding block, is clamped with the clamping part has certain deformation capacity, so that the clamping part can be directly pressed in the clamping part from top to bottom when in use.

Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses a set up a blade hosel between blade and handle of a knife, the handle of a knife rotates with the blade hosel through the pivot to be connected, still be equipped with the slot that is used for fixed blade on the blade hosel, one side of blade is equipped with concave position draw-in groove, interval between the concave position draw-in groove is the same, just so formed two draw-in grooves, one side at the blade hosel is equipped with the slider, slider one end and blade hosel pin joint, the other end and blade hosel joint, and be equipped with the spacing protruding muscle that agrees with mutually with the recess of blade in one side of slider, just so can fix the blade on the blade hosel through the slider. Compared with the traditional butterfly knife, the utility model discloses a blade is changed more conveniently, swiftly.
