AI Technical Summary
After long-term use of the traditional folding knife, the friction between the blade and the handle is reduced, which can easily lead to the blade being disengaged, posing a safety hazard. At the same time, the existing folding knife with a locking structure is costly and is not conducive to mass production.
A folding knife with locking function is designed. The blade is hinged with the handle through the hinge ring. The handle is hinged with a locking shank. The end of the locking shank is equipped with a locking column. An elastic member is installed in the arc-shaped groove. When folded, the end of the blade is against the locking column. The locking column is abutted and the locking column is opened. The blade enters the locking position. The locking column is then reset under the action of the elastic member to prevent the blade from falling out.
The locking structure of the folding knife is simple, the production cost is low, the locking is stable after folding, and the blade will not be disengaged due to vibration after long-term use, eliminating safety hazards, and the user experience is good, suitable for mass production.

[0006] Furthermore, the elastic component is a spring sheet or a spring block.
[0007] Furthermore, the hinge ring is mounted with a hinge ring bottom cover by means of screws, and the hinge ring and the hinge ring bottom cover clamp the blade and the handle.
[0008] Furthermore, the locking handle is provided with a hinged column, and the blade is provided with an opening positioning groove corresponding to the hinged column.
[0009] Furthermore, the blade is provided with a folding positioning groove corresponding to the hinge column.
[0010] Furthermore, the locking handle is provided with a locking handle top cover.
[0011] Furthermore, the locking handle top cover is mounted on the locking handle via a locking screw.
[0012] Furthermore, the blade is provided with an opening operation strip.
[0013] Furthermore, the locking handle is arranged in an arc shape.
[0014] Furthermore, the blade and the handle are both provided with sleeve holes sleeved on the hinge ring.
[0015] Compared with the prior art, the utility model is a locking handle hingedly connected to the knife handle, and the end of the locking handle is provided with a locking column for the end of the blade to abut against, and the knife handle is provided with an arc groove for the locking column to be slidably connected, and an elastic component that abuts against the locking column is installed in the arc groove. When folded, the end of the blade abuts against the locking column, the locking column is pushed open, and the blade enters a locked position. The locking column is then reset to its original position under the action of the elastic component. At this time, the locking column prevents the blade from falling out, so that the locking structure of the folding knife is simple, the production cost is low, and the locking is stable after folding. After long-term use, the blade will not fall out when the blade and the handle are vibrated, thereby eliminating safety hazards, providing a good user experience, and facilitating mass production.
