Abstract

The invention provides a folding knife fastened without a thread or screw. The folding knife comprises a blade, a bottom rib, a left handle piece and a right handle piece, the left handle piece and the right handle piece are arranged at the two sides of the bottom rib, first lock catch holes, second lock catch holes, third lock catch holes and main shaft holes are correspondingly formed in the left handle piece and the right handle piece, and a first lock piece, a second lock piece and a third lock piece are fixedly arranged on the bottom rib. The first lock piece, the second lock piece and the third lock piece are each provided with a second convex shaft, a third convex shaft and a second concave shaft, the second convex shafts are fixedly connected with the bottom rib, and the third convex shafts and the second concave shafts protrude out of the two sides of the bottom rib and are buckled in the first lock catch holes, the second lock catch holes and the third lock catch holes to move front and back, and the aim of assembling or disassembling the folding knife is achieved. By the adoption of the structure, the first lock piece, the second lock piece and the third lock piece are effectively used for replacing the inconvenience that a folding knife is fixed through screws and threads in the prior art, all parts of the folding knife can be detached by hands to be cleaned, detaching and assembling are easy, a beginner and an experienced man both can operate the folding knife, the delivery rate is effectively increased, machining cost is reduced, and practicability is high.

Description

technical field [0001] The invention relates to a jackknife fastened without threaded screws. Background technique [0002] Folding knives are tools often used by people for outdoor activities and travel. Because the folding knives can be folded to reduce the overall volume, they are very convenient to carry when traveling and outdoor activities.
