[0016] See Figure 1 , Figure 2 and Figure 3This utility model discloses an assembly fixture for concealed nails inside a handle, comprising a lower mold 1, a positioning groove 2, a cutting tool head 3, a handle limiting groove 4, a cutting tool handle 5, a limiting connecting post 6, a through connecting groove 7, a fixing nail 8, a nail mounting post 9, and an upper mold 10. The lower mold 1 has a through positioning groove 2 on its side. The cutting tool head 3 is positioned within the positioning groove 2. The upper part of the positioning groove 2 has a handle limiting groove 4. The top of the cutting tool head 3 is fitted with a cutting tool handle 5, which is positioned within the handle limiting groove 4. The top of the cutting tool head 3 extends to form a limiting connecting post 6. The inside of the cutting tool handle 5, corresponding to the position of the limiting connecting post 6, has a through connecting groove 7. The upper part of the through connecting groove 7 is fitted with a fixing nail 8, which is fixedly connected to the top of the limiting connecting post 6. The top of the fixing nail 8 is detachably connected to the nail mounting post 9. The concealed rivet mounting post 9 is fixedly mounted on the top of the upper mold 10 of the fixture, which is located directly above the through connecting groove 7. The lower mold 1 and the upper mold 10 of the fixture are fixedly mounted at both ends of the press, respectively. The maximum width of the positioning groove 2 is less than the maximum width of the handle limiting groove 4. The center lines of the positioning groove 2 and the handle limiting groove 4 are located on the same plane. An auxiliary limiting post is provided on the side of the limiting connecting post 6. An auxiliary limiting groove is provided inside the tool handle 5 corresponding to the position of the auxiliary limiting post. The fixed concealed rivet 8 is a rivet. A limiting groove is provided at the bottom of the concealed rivet mounting post 9 corresponding to the position of the fixed concealed rivet 8. A diameter-reducing inner push rod is provided at the top of the limiting connecting post 6 corresponding to the position of the fixed concealed rivet 8. An expansion guide section is coaxially provided at the upper part of the through connecting groove 7. The inner diameter of the expansion guide section is greater than the maximum outer diameter of the fixed concealed rivet 8 and the concealed rivet mounting post 9. The top outer diameter of the fixed concealed rivet 8 is greater than the inner diameter of the through connecting groove 7.

[0017] The working process of this utility model is as follows: The upper mold 10 and the lower mold 1 of the fixture are fixed at both ends of the press. The tool functional head 3 is placed in the positioning groove 2. The tool handle 5 is sleeved on the limiting connecting post 6 of the tool functional head 3. Then, the tool handle 5 is limited and fixed by the handle limiting groove 4. The fixing hidden nail 8 is introduced into the through connecting groove 7 and connected to the limiting connecting post 6. The press is started, and the upper mold 10 and the lower mold 1 of the fixture approach each other for operation. The hidden nail mounting post 9 rivets and fixes the fixing hidden nail 8 to the limiting connecting post 6. Thus, the tool handle 5 and the tool functional head 3 are fastened together by the cooperation of the limiting connecting post 6 and the through connecting groove 7. The upper mold 10 and the lower mold 1 of the fixture separate for operation, and the assembly and fixing of the tool handle 5 is completed.

[0018] This utility model combines the lower mold 1, positioning groove 2, cutting tool head 3, handle limiting groove 4, cutting tool handle 5, limiting connecting post 6, through connecting groove 7, fixing hidden nail 8, hidden nail mounting post 9, and upper mold 10 of the fixture.
