[0033] Example: As attached Figures 1-6 The illustrated handle structure includes a handle base 1 and a handle 2 rotatably connected to the handle base 1. The handle base 1 includes a bottom cover 3 and a fixing plate 4. The fixing plate 4 has at least two through holes 5. The bottom cover 3 has a number of connecting plates 6 corresponding to the number of through holes 5, which pass through the corresponding through holes 5 and form a riveted fit with the bottom cover 3. In this embodiment, there are two through holes 5 and two connecting plates 6. The bottom cover 3 and the fixing plate 4 are connected by riveting. Compared with the screw connection method used in the prior art, this method is not only easier to assemble but also lower in cost. In mass production, it has a significant price advantage and can effectively enhance market competitiveness.

[0034] The connecting piece 6 and the bottom cover 3 are integrally formed, and the connecting piece 6 is formed by partially bending the bottom cover 3. This design is very convenient to manufacture and has high structural strength.

[0035] As attached Figure 4 and attached Figure 5 As shown, the connecting piece 6 includes a support portion 7 extending toward the fixing piece 4 and a riveting portion 8 disposed at the end of the support portion 7. In this embodiment, the support portion 7 is perpendicular to the bottom cover 3, and the riveting portion 8 is perpendicular to the support portion 7. The riveting portion 8 passes through the through hole 5 and is bent to abut against the end of the fixing piece 4 away from the bottom cover 3. The connecting piece 6 is formed by bending, making its manufacturing process very convenient.

[0036] As attached Figure 5 As shown, the support portion 7 has outwardly extending reinforcing protrusions 9 on both sides of the end away from the bottom cover 3, and the reinforcing protrusions 9 abut against the fixing piece 4. This design can improve the stability of the support portion 7 abutting against the fixing piece 4, making the riveted structure less prone to loosening.

[0037] As attached Figure 4 and attached Figure 5 As shown, the fixing piece 4 has a recessed portion 10 at the position corresponding to each through hole 5 on its side. The recessed portion 10 is formed by stamping, and the riveting portion 8 is embedded in the recessed portion 10. This design ensures that the back of the fixing piece 4 is flat, avoiding the situation where the back of the fixing piece 4 protrudes and cannot be properly fitted with the mounting surface.

[0038] As attached Figure 5 and attached Figure 6 As shown, the inner end of the bottom cover 3 is provided with at least two tension sleeves 11 extending toward the fixing piece 4. The inner side of the tension sleeve 11 is provided with internal threads 12. The bottom cover 3 is provided with a number of mounting holes 13 corresponding to the tension sleeves 11.
