[0022] like Figures 1 to 4 As shown, an axis-lock folding knife with an integrally molded handle comprises a blade 1, a handle 2, an axis-locking structure and a lining 3. One end of the blade 1 is rotatably connected to the front end of the handle 2. The handle 2 and the lining 3 are integrally molded, and mounting holes 5 are symmetrically provided on opposite sides of the handle 2. A decorative sheet 6 is detachably provided on the mounting hole 5. The lining 3 is detachably mounted on the mounting hole 5 by screws, and the axis-locking structure passes through the mounting hole 5 and slides with the axis-locking groove 7 on the lining 3. In the above embodiment, the lining 3 is integrally bent and molded by a metal sheet, and the handle 2 can be integrally injection molded by plastic, or integrally bent and molded by a metal sheet. The decorative sheet 6 can be detachably fixed on the mounting hole 5 by screws.

[0023] Compared with the existing axis-lock folding knives, the axis-lock folding knife with an integrally formed handle of the utility model adopts an integrally bent handle 2 and lining 3, which has a simple structure and is easy to produce and process. At the same time, the integrally formed handle 2 and lining 3 have high structural strength and are easier to control processing accuracy. There is no need to set screws, spacers and other accessories on the handle 2, which reduces the use of accessories and can avoid the influence of different accessories on the overall appearance of the folding knife due to large material and color differences. In addition, a mounting hole 5 is provided on the handle 2 to facilitate the installation of the axis-locking structure, and a decorative piece 6 is provided at the mounting hole 5, which can play a certain protective role on the axis-locking structure and improve the aesthetics of the appearance of the folding knife.

[0024] In one specific embodiment, the knife handle 2 includes a first sheet 8 and a second sheet 9 arranged parallel to each other, and a connecting portion 10 connecting the upper edges of the first sheet 8 and the second sheet 9, that is, the cross-section of the knife handle 2 is "n"-shaped, and a gap is constructed between the first sheet 8 and the second sheet 9 to accommodate the lining 3, and the front ends of the first sheet 8 and the second sheet 9 are symmetrically provided with mounting holes 5.

[0025] In one of the preferred embodiments, the outer surfaces of the first sheet 8 and the second sheet 9 may be provided with a mounting groove 11 for mounting the decorative sheet 6, and the mounting hole 5 is provided in the middle of the mounting groove 11. By providing the mounting groove 11, the stability of the installation of the decorative sheet 6 can be improved. At the same time, most of the decorative sheet 6 is located in the mounting groove 11 after installation, and will not protrude too high from the surface of the handle 2. The surface of the handle 2 is also smoother, less likely to scratch the hand, and more aesthetically pleasing.

[0026] In another preferred embodiment, the inner surfaces of the first sheet 8 and the second sheet 9 are provided with limiting grooves 12 for installing the lining 3, and the opposite sides of the lining 3 can be inserted into the limiting grooves 12, so that the lining 3 can be positioned through the limiting grooves 12, so as to facilitate the fixed installation of the lining 3. At the same time, by providing the limiting grooves 12, the stability of the installation of the lining 3 can also be improved. Furthermore, the connection part 10 at the front end of the handle 2 is provided with an installation opening 13 for installing the lining 3. When installing, the lining 3 can be placed in the limiting groove 12 through the installation opening 13 at the front end of the handle 2 to facilitate the installation of the lining 3.

[0027] The shaft lock groove 7 extends along the length direction of the knife handle 2, and an escape position 14 is provided at one end of the shaft lock groove 7 close to the rear end of the knife handle 2. By providing the escape position 14, the width of the escape position 14 is greater than the width of the shaft lock groove, so as to facilitate the installation of the shaft lock structure.

[0028] The decorative sheet 6 is provided with a slide groove 15, and the shaft lock structure includes a shaft body 4 and a spring 16. The middle part of the shaft body 4 is slidably matched with the shaft lock groove 7, and the two ends of the shaft body 4 are respectively provided with a pushing part 17 that is slidably matched with the slide groove 15, and the pushing part 17 protrudes from the outer surface of the decorative sheet 6. The end of the blade 1 connected to the handle 2 is provided with a first clamping position and a second clamping position. When the shaft body 4 is clamped in the first clamping position, the blade 1 can be locked in a fully open state; when the shaft body 4 is clamped in the second clamping position, the blade 1 can be locked in a fully closed state. The shaft body 4 can be driven by the pushing part 17 to slide backward along the slide groove 15, so that the shaft body 4 can be disengaged from the first clamping position or the second clamping position, so that the blade 1 can rotate relative to the handle 2. One end of the spring 16 is connected to the lining 3, and the other end is connected to the shaft body 4. Under the action of the elastic force of the spring 16, the shaft body 4 has the ability to move forward along the slide groove 15, so that the shaft body 4 can stably maintain the state of being clamped in the first clamping position or the second clamping position.

[0029] In order to facilitate the carrying of the folding knife, an elastic clip 18 can be installed on the handle 2. Furthermore, a lanyard hole 19 can be provided at the rear end of the handle 2 to facilitate the user to wear a lanyard, a hanging buckle or other hanging accessories.

[0030] The above embodiments are only used to illustrate the technical solution of the utility model but not to limit it. Any modification or equivalent substitution that does not deviate from the spirit and scope of the utility model shall be included in the scope of the technical solution of the utility model.
