Description

Technical Field

[0001] The utility model relates to the technical field of cutters, in particular to a cutter and a clip rotation adjustment structure thereof. Background Art

[0002] When people are doing outdoor sports, they often carry various tools with them for easy access. For longer or sharper tools, such as knives, sheaths and devices for connecting clips are needed. At the same time, to make carrying tools safer and more comfortable, and to facilitate quicker and more convenient tool removal, tools that can be freely rotated and maintained in a certain position as needed will be more popular. Existing invention patent 201610603232.5 discloses a sheath and a knife with such a sheath. The bottom surface of the clip is provided with multiple small holes, a spring sheet and a pin fixed to the spring sheet. By separating the spring sheet and the pin from the small hole, the sheath can be rotated. The pin cooperates with the small holes in different positions to rotate the sheath to different positions. Although this structure can also implement the rotation of the sheath, the deformation of the spring sheet causes the corresponding change in the position of the pin, which requires a larger fitting clearance to achieve it. The size and number of the small holes and the size and height of the pins have certain limitations, which makes it difficult to accurately maintain the sheath in a specific position. Moreover, when the spring sheet is turned to unlock, the gravity of the unbalanced center of gravity of the sheath may cause an accidental downward rotation due to gravity, causing the tool to accidentally fall out, which poses an unsafe factor. In addition, this operation is not simple and convenient enough. Summary of the Invention

[0003] The present invention aims to solve at least one of the above-mentioned technical problems and provide a knife and a clip rotation adjustment structure thereof, which can accurately control the rotation angle of the sheath and is simple, convenient, safe and reliable to operate.

[0004] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is as follows: a clip rotation adjustment structure of a tool, comprising a mounting seat, a clip, and a rotating mechanism connecting the mounting seat and the clip, the mounting seat being fixedly mounted on the sheath, the rotating mechanism comprising a toothed disc, a lock buckle, a press switch and an elastic reset member, the toothed disc being mounted on the clip buckle and being able to rotate synchronously with the clip buckle relative to the mounting seat, the lock buckle being rotatably mounted on the mounting seat, and being provided with a locking tooth portion that is engaged with the tooth surface of the outer edge of the toothed disc, the press switch being elastically connected to the lock buckle through the elastic reset member, when the press switch is pressed, the elastic reset member can be compressed and the lock buckle can be driven to rotate so that the lock buckle is separated from the toothed disc, and when the press switch is not pressed, the elastic force of the elastic reset member can make the press switch abut against the lock buckle, and the lock tooth portion of the lock buckle can maintain an engaged state with the tooth surface of the outer edge of the toothed disc.

[0005] Preferably, the toothed disc and the clip are rotatably connected to the mounting seat via a shaft sleeve, and a connecting shaft and a screw that are threadedly matched with each other are respectively provided at both ends of the shaft sleeve to limit the axial movement of the toothed disc and the clip along the shaft sleeve.

[0006] Preferably, the toothed disc is provided with a plurality of limiting holes, the clip is provided with a boss, and the boss is provided with a plurality of limiting columns which are plugged and matched with the limiting holes in a one-to-one correspondence.

[0007] Preferably, a mounting groove is provided on the mounting seat, and a fixing plate is detachably fixedly installed on the mounting groove to form a mounting chamber for installing the rotating mechanism, a limiting portion for limiting the push switch is provided in the mounting chamber, and an opening for allowing the push switch to extend is provided on one side of the mounting seat.

[0014] The beneficial effect is: compared with the prior art, the tool and its clip rotation adjustment structure of the utility model connect the mounting seat and the clip by setting a rotating mechanism. When the sheath needs to be rotated, the push switch is pressed to compress the elastic reset part and drive the lock buckle to rotate, so that the lock buckle is separated from the toothed disk, so that the sheath can be rotated to the desired position. When the push switch is released, the push switch and the lock buckle can be driven to move to the initial state under the action of the elastic reset part's elastic force, and the push switch can abut against the lock buckle, so that the lock tooth portion of the lock buckle and the outer edge tooth surface of the toothed disk remain in a locked state.

[0027] like Figures 1 to 7 As shown, the present application discloses a clip rotation adjustment structure of a tool, comprising a mounting base 1, a clip 2, and a rotation mechanism connecting the mounting base 1 and the clip 2. The mounting base 1 is fixedly mounted on the sheath 26. The rotation mechanism comprises a toothed disc 3, a lock buckle 4, a press switch 5 and an elastic reset member 6. The toothed disc 3 is mounted on the clip buckle 2 and can rotate synchronously with the clip buckle 2 relative to the mounting base 1. The lock buckle 4 is rotatably mounted on the mounting base 1 and is provided with a locking tooth portion 7 that engages with the tooth surface of the outer edge of the toothed disc 3. The press switch 5 is elastically connected to the lock buckle 4 through an elastic return member 6. Preferably, the elastic return member 6 can be a return spring. When the push switch 5 is pressed, the elastic return member 6 can be compressed and drive the lock buckle 4 to rotate, so that the lock buckle 4 is separated from the toothed disc 3. When the push switch 5 is not pressed, or the push switch 5 is released after being pressed, the elastic force of the elastic return member 6 can make the push switch 5 abut against the lock buckle 4, and keep the lock tooth portion 7 of the lock buckle 4 in a locked state with the outer tooth surface of the toothed disc 3.

[0028] The utility model provides a clip rotation adjustment structure of a tool by providing a rotating mechanism to connect the mounting base 1 and the clip 2. When the sheath 26 needs to be rotated, the push switch 5 is pressed to compress the elastic reset member 6 and drive the lock buckle 4 to rotate, so that the lock buckle 4 is separated from the toothed disc 3, so that the sheath 26 can be rotated to the desired position. When the push switch 5 is released, the elastic reset member 6 can drive the push switch 5 and the lock buckle 4 to move to the initial state, and the push switch 5 can abut against the lock buckle 4, so that the lock tooth portion 7 of the lock buckle 4 and the outer edge tooth surface of the toothed disc 3 remain in a locked state. At this time, the sheath 26 cannot rotate relative to the clip 2, thereby maintaining a stable locking state.

[0029] In one specific embodiment of the present application, the toothed disc 3 and the clip 2 can be rotatably connected to the mounting seat 1 through the shaft sleeve 8. The toothed disc 3 and the clip 2 are both provided with shaft holes that rotatably cooperate with the shaft sleeve 8. The middle part of the shaft sleeve 8 is penetrated and a shaft cap is provided at one end. The two ends of the shaft sleeve 8 are also respectively provided with a connecting shaft 9 and a screw 10 that are threadedly engaged with each other. One end of the connecting shaft 9 is provided with a nail cap that abuts the shaft cap, and the other end is inserted from the middle part of the shaft sleeve 8 and threadedly engaged with the screw 10. The shaft cap of the shaft sleeve 8 and the nail cap of the screw 10 abut the toothed disc 3 and the mounting seat 1 respectively, so as to limit the axial movement of the toothed disc 3 and the clip 2 along the shaft sleeve 8.

[0030] In the present application, a number of limiting holes 11 can be provided on the toothed disc 3, a boss 25 is provided on the clip 2, and a number of limiting columns 12 that are plugged into and matched with the limiting holes 11 are provided on the boss 25. Preferably, four limiting holes 11 are evenly distributed around the axis of the toothed disc 3, and four limiting columns 12 are correspondingly provided on the clip 2. The boss 25 is provided to fit with one side surface of the toothed disc 3, and the toothed disc 3 is detachably installed on the clip 2 by adopting an insert-installation method, so that the toothed disc 3 can rotate synchronously with the clip 2 relative to the mounting seat 1, and the structure is simple and easy to disassemble and assemble.

[0031] In order to facilitate the installation of the rotating mechanism, a mounting groove 13 is provided on the mounting base 1, and a fixing plate 14 is detachably fixedly installed on the notch at the top of the mounting groove 13 by a fixing nail to form an installation chamber for installing the rotating mechanism. The rotating mechanism is arranged in the installation chamber, and a limiting portion 15 for limiting the press switch 5 is provided in the installation chamber. When the elastic reset member 6 drives the press switch 5 to reset, the limiting portion 15 can abut against the press switch 5, thereby limiting the press switch 5 so that the press switch 5 moves to the initial state, and the installation chamber is provided with an opening on one side of the mounting base 1 for allowing the press switch 5 to extend, so that a part of the press switch 5 protrudes from the outside of the mounting base 1 to facilitate pressing the press switch 5.

[0032] To facilitate the installation of the toothed disc 3 and the clip 2, a mounting hole 16 for mounting the toothed disc 3 and the clip 2 is provided at the bottom of the mounting groove 13. The mounting hole 16 is circular and has a diameter larger than that of the toothed disc 3. During installation, the toothed disc 3 and the clip 2 can be installed through the mounting hole 16 after the fixing plate 14 is installed. In addition, to facilitate the installation of a return spring, a spring groove 28 can be provided at the bottom of the mounting groove 13. One end of the return spring abuts against the groove wall at one end of the lock buckle 4, and the other end abuts against the push switch 5.

[0033] The cam 17 is engaged with the tooth surface of the outer edge of the toothed disc 3 and the toothed disc 3 is engaged with the toothed disc 3 when the cam 17 is engaged with the toothed disc 3.

[0034] In another preferred embodiment of the present application, two lock buckles 4 can be provided, and the locking teeth 7 of the two lock buckles 4 can respectively engage with the outer edges of the two symmetrical sides of the toothed disc 3, so that the force on the toothed disc 3 is more balanced, and the stability of the sheath 26 when locked is improved. In the installation structure of the lock buckle 4, the middle part of the lock buckle 4 can be rotatably connected to the mounting base 1 through the shaft 19. The middle part of each of the two lock buckles 4 is provided with a connecting hole 30, which is rotatably engaged with the rotating shaft, and a recessed portion 31 is provided at the connecting hole 30, so that after the two lock buckles 4 are stacked on the rotating shaft, the locking teeth 7 of the two lock buckles 4 are located on the same plane, so that the two lock buckles 4 can engage with the toothed disc 3 at the same time. One end of the lock buckle 4 is provided with an abutment portion 20 that abuts against the push switch 5, and one side of the other end is provided with the aforementioned locking teeth 7, and the other side is provided with an arc-shaped guide portion 21.

[0035] The latch 4 is then released from the engagement with the toothed disc 3 and the latch 4 is engaged with the toothed disc 3.

[0036] In addition, if Figure 8As shown, the present application also discloses a cutting tool, comprising a sheath 26, a blade body 27, and the above-mentioned clip rotation adjustment structure. A cutting tool of the present invention is connected to the mounting base 1 and the clip 2 by setting a rotation mechanism. When the sheath 26 needs to be rotated, by pressing the push switch 5, the elastic reset member 6 can be compressed, and the lock 4 can be driven to rotate, so that the lock 4 is separated from the toothed disc 3, so that the sheath 26 can be rotated to the desired position. When the push switch 5 is released, the elastic reset member 6 can drive the push switch 5 and the lock 4 to move to the initial state, and the push switch 5 can abut against the lock 4, so that the lock tooth portion 7 of the lock 4 and the outer edge tooth surface of the toothed disc 3 remain in a locked state. At this time, the sheath 26 cannot rotate relative to the clip 2, thereby maintaining a stable locking state.

[0037] The above embodiments are only used to illustrate the technical solution of the present invention and are not intended to limit the present invention. Any modification or equivalent replacement that does not depart from the spirit and scope of the present invention shall be included in the scope of the technical solution of the present invention.
