Through the cooperation between the clamping part 4 and the outer side of the handle, the folding knife can be stably clamped on the clamped object.

[0023] The utility model provides an adjustable nail-free clip installation structure. By providing an installation groove 9 on the inner side of the knife handle 2, the plug-in portion 5 can be inserted into the installation groove 9 through the groove, and the positioning slot 8 on the clip 3 is engaged with the clamping portion 10 at the groove, so that the clip 1 is installed on the knife handle 2. At the same time, the two elastic arms 7 can be pressed to drive the two elastic arms 7 to move toward each other, so that the clamping portion 10 slides out of the positioning slot 8, so that the clip 3 can be pushed into the installation groove 9 or pulled out from the installation groove 9 as needed to adjust the length of the clip 1 extending out of the knife handle 2, and the clamping portion 10 cooperates with the corresponding positioning slot 8 to achieve the fixation of the clip 3. The installation structure of the clip 1 is simple and easy to adjust.

[0024] In this embodiment, positioning slots 8 can be symmetrically arranged on the elastic arms 7 on the opposite sides of the clip 3, and the opposite sides of the slots are symmetrically provided with snap-fitting portions 10 that respectively snap-fit ​​with the positioning slots on the two sides of the clip 3.
