[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.
[0022] Refer to Figures 1 - 4 , a tool bit clamp with an adjustment function, including a connector 1 and a tool bit assembly. The cross-section of the connector 1 is a cross-shaped structure. A cross clamp 4 is integrally formed on one side of the connector 1. A third thread groove 10 is provided on the outer surface of the cross clamp 4, and a locking pen cap 11 is threadedly connected to the outer surface of the third thread groove 10. The locking pen cap 11 is specifically a metal pen cap. The locking pen cap 11 is sleeved on the outside of the cross clamp 4. The locking pen cap 11 squeezes the cross clamp 4. Through the squeezing of the cross clamp 4 by the locking pen cap 11, not only the fixing effect of tool bit assemblies of different sizes is ensured, but also the contact position between the depth adjustment rod 8 and the tool bit assembly is adjusted. The user can precisely adjust the working depth of the tool bit to adapt to different types of materials and working requirements. An installation hole penetrating the cross clamp 4 is provided at one end of the cross clamp 4. A threaded hole 5 penetrating the connector 1 is provided at one end of the connector 1, and the threaded hole 5 communicates with the installation hole. A depth adjustment rod 8 is threadedly connected to the inner wall of the threaded hole 5. A second thread groove 9 is provided on the outer surface of one side of the depth adjustment rod 8, and the second thread groove 9 is threadedly connected to the threaded hole 5. The inner wall of the installation hole is inserted into the tool bit assembly, and one end of the depth adjustment rod 8 is in contact with one end of the tool bit assembly.
[0023] Among them, a first thread groove 2 is provided at one end of the connector 1, and a plastic handle body 3 is threadedly connected to the outer surface of the first thread groove 2. A plurality of anti-slip grooves 1101 are provided on the outer surface of the locking pen cap 11. The top end of the locking pen cap 11 is a conical structure. The conical structure can well squeeze the cross clamp 4, so as to more conveniently fasten and fix the tool bit assembly. The tool bit assembly includes a knife handle 6, and a tool bit 7 for engraving is integrally formed at one end of the knife handle 6.
[0024] Among them, one end of the connecting head 1 is clamped with an elastic rubber ring 12, and the rubber ring 12 is located on one side of the cross clamp 4. One end of the connecting head 1 is inserted with a plastic handle cap 13, and the plastic handle cap 13 can protect the blade assembly to prevent the blade from being scratched. The plastic handle cap 13 is clamped with the rubber ring 12, and the cross clamp 4 is located in the plastic handle cap 13. The plastic handle body 3 and the plastic handle cap 13 are lightweight in design, which is easy to use and carry. The outer surface of the plastic handle body 3 and the plastic handle cap 13 is a frosted structure, which can have a certain anti-slip effect.
[0025] The working principle of this embodiment is as follows: when a hand knife is needed, first of all, before using the hand knife, the user needs to make the front-end preparation, mainly disassembling the knife, pulling out the plastic handle cap 13, then rotating the locking pen cap 11 counterclockwise to loosen the cross clamp 4, and then taking the knife head assembly out of the packaging box, and then inserting the knife handle 6 on the knife head assembly along the mounting hole at one end of the cross clamp 4 to ensure the perfect connection between the knife handle 6 and the cross clamp 4, and then rotating the plastic handle body 3 to separate the plastic handle body 3 from the connector 1, and releasing the plastic handle body 3 from the connector. The connector 1 is connected, and then the depth adjustment rod 8 at one end of the connector 1 is turned to drive the depth adjustment rod 8 to be pushed out and retracted along the threaded hole 5. The length of the corresponding appropriate cutter head assembly can be manually adjusted according to different cutter heads and usage habits or different usage scenarios. After the depth adjustment is completed, the locking pen cap 11 is turned clockwise, and the locking pen cap 11 will gradually press the cross clamp 4 to clamp and fix the cutter head assembly. After use, the plastic handle cap 13 is put on one side of the connector 1, and the rubber ring 12 squeezes and fixes the plastic handle cap 13.
[0026] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
