the utility model provides a folding knife with location structure, includes first handle of a knife halfbody, clamp splice, second handle of a knife halfbody, tool bit, main shaft, through-hole, spring, install at the rear of first handle of a knife halfbody the second handle of a knife halfbody, the second handle of a knife halfbody with install between the first handle of a knife halfbody the clamp splice first handle of a knife halfbody with between the second handle of a knife halfbody and just install one side of clamp splice the main shaft, install on the main shaft the tool bit, the shaping has on the tool bit the through-hole, the main shaft passes the through-hole is inside and be in install in the outside of main shaft the spring.

Preferably: the clamping block is fixedly connected with the first tool handle half body and the second tool handle half body through screws.

So set up, through screw fastening connection be convenient for connect quick assembly disassembly between the two fixed.

Preferably: the main shaft is connected with the first tool handle half body and the second tool handle half body through clamping grooves.

So set up, it is right to utilize the draw-in groove to realize the fixed of main shaft, avoid when the tool bit rotates, the main shaft also takes place to rotate.

Compared with the prior art, the utility model has the following beneficial effects:

when the tool bit is in the open position, the spring acts on the upper end of the main shaft, so that the tool bit is positioned in a normal use state, when the tool bit rotates, the spring gradually breaks away from the upper end of the main shaft and moves along the cylindrical surface of the main shaft, the spring is compressed at the moment, when the tool bit gradually rotates to the closed position, the spring acts on the lower end of the main shaft and gradually releases elastic force, and when the two are completely matched with each other in place, the tool bit is in the closed positioning state.
