The connecting part is a hollow structure, and an internal thread section is provided at the upper end. The lower end of the operating rod is provided with an external thread section that is screwed together with the internal thread section. A bayonet is provided on the side wall of the connecting part, and a plug-in part is provided at the upper end of the tool head. A radially adjustable clamping block is protruded on the side wall of the plug-in part. The plug-in part is inserted into the connecting part and is quickly disassembled and assembled by cooperating with the clamping block and the bayonet.

[0005] Furthermore, the side wall of the plug-in portion is provided with an inverted U-shaped groove outside the clamping block.

[0006] Furthermore, a positioning opening is provided at the lower end of the connecting piece, and a positioning protrusion that cooperates with the positioning opening is provided on the side wall of the plug-in portion.

[0007] Furthermore, a hanging ring is provided at the upper end of the operating rod, an annular protrusion is provided at the lower end of the hanging ring, and an annular groove cooperating with the annular protrusion is provided on the inner wall of the upper end of the operating rod.

[0008] Furthermore, the tool head is a shovel head.

[0009] Furthermore, the tool head is a brush head.

[0010] The beneficial effects of the present invention over the prior art are as follows: the present invention has a segmented design, a simple structure, and is easy to assemble and disassemble; damaged parts can be replaced individually, and the service life is extended. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Figure 1 An exploded view of the tool part involved in the utility model;

[0012] Figure 2 This is a schematic diagram of an integrated structure of the operation and hanging ring involved in the present invention;

[0013] Figure 3It is a three-dimensional diagram of the brush head involved in the present utility model. DETAILED DESCRIPTION

[0014] like Figure 1 、 Figure 2 As shown, a new tool part of an embodiment of the present utility model includes a connecting piece 1 and an operating rod 2; wherein, the connecting piece 1 is a hollow structure, and an internal thread section is provided at the upper end, and an external thread section 3 is provided at the lower end of the operating rod 2. The external thread section 3 of the operating rod 2 is inserted into the internal thread section and screwed together with the internal thread section. The length of the operating rod 2 can be selected according to needs; at the same time, a hanging ring 10 is provided at the upper end of the operating rod 2, and the operating rod 2 and the hanging ring 10 can be an integrated or split setting. The lower end of the hanging ring 10 in the split type is provided with an annular protrusion 11, and the inner wall of the upper end of the operating rod 2 is provided with an annular groove that cooperates with the annular protrusion 11. The hanging ring 10 has a slight elasticity, and the annular protrusion 11 on the hanging ring 10 can be hard-fitted into the annular groove during installation.

[0015] Further, if Figure 1 、 Figure 3 As shown, the lower end of the connecting piece 1 of this embodiment is provided with a tool head, which can be a shovel head 12 or a brush head 13 or other common tool heads to adapt to different application scenarios, with diverse functions and strong adaptability; wherein, a bayonet 4 is provided on the side wall of the connecting piece 1, and a plug-in portion 5 is provided on the upper end of the tool head, a clamping block 6 is protruding on the side wall of the plug-in portion 5, and an inverted U-shaped groove 7 is provided outside the clamping block 6. The clamping block 6 can be radially adjusted in the inverted U-shaped groove 7 after being subjected to force. When the plug-in portion 5 is inserted into the connecting piece 1, the tool head and the connecting piece 1 can be quickly disassembled and assembled by the clamping block 6. At the same time, a positioning port 8 is provided at the lower end of the connecting piece 4, and a positioning protrusion 9 is provided on the side wall of the plug-in portion 5. The positioning protrusion 9 cooperates with the positioning port 8 to limit the rotation of the assembled tool head. It has a simple structure, is easy to disassemble and assemble, and is extremely practical.

[0016] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
