Detailed Description

In order to facilitate understanding of the present invention, the present invention will be described more fully hereinafter with reference to the accompanying drawings. The preferred embodiments of the present invention are shown in the drawings.

Referring to fig. 1-7, a locking protection device of a wire-lock folding knife comprises a knife body 1, a first knife handle 2 and a second knife handle 6, wherein the knife body 1 can be folded and collected in a space formed by the first knife handle 2 and the second knife handle 6; the top of the first cutter handle 2 is provided with a locking strip 9 capable of generating elastic deformation, a mounting hole 10 is formed in the position, adjacent to the first cutter handle 2, of the locking strip 9, a knob 8 and a stop block 7 are arranged on two sides of the mounting hole 10 respectively, the knob 8 and the stop block 7 are used for driving the stop block 7 to rotate when the cutter body 1 is opened, and the stop block 7 blocks the locking strip 9 to prevent the locking strip 9 from accidentally retracting, so that safety protection is achieved, and accidental unlocking and closing of the cutter body 1 in the using process are avoided.

In the present embodiment, the knob 8 is located at the outer side of the first blade handle 2, and the outer side of the knob 8 is provided with a rotating strip 81; the stopper 7 is positioned on the inner side of the first knife handle 2, the tail end of the stopper 7 protrudes to form a blocking bulge 71, and the blocking bulge 71 is used for controlling the locking strip 9 to be elastically deformed and preventing the locking strip 9 from returning.

In this embodiment, an arc-shaped sliding groove is disposed outside the mounting hole 10, the sliding groove spans the first handle 2 and the locking bar 9, the sliding groove is located on one side of the first handle 2 and is a locking groove 91, and the sliding groove is located on one side of the locking bar 9 and is an unlocking groove 21.
