Problems solved by technology

[0003] However, among the many tool rods that can be assembled, in order to ensure their stability and use strength, the connection between most of the rods needs to be connected and fixed by additional connecting parts such as bolts. During the assembly process, the bolts are screwed and other additional connectors also need to be operated by the user on the spot. If the user is a woman or a group with less strength, this connection method still cannot achieve the purposes of quick installation and easy assembly, and it is often confused with loosening the fastening sleeve and Loosen the operating sequence of the rod body and damage the connecting parts, which in turn affects the assembly and use of the tool

Embodiment 1

[0038] The connection structure is used to connect the rod body to the rod body. This structure also includes a connecting pipe 11. The free ends of the outer sleeve 1 and the connecting pipe 11 are cylindrical pipe bodies. The length of this part of the pipe body is adjusted according to actual needs to match different length requirements. The tool is also connected through the connection structure between the rod body and the rod body. Such as figure 2 As shown, two adjacent rod bodies are connected through this connection structure, and the outside of the connecting pipe and the outer sleeve is set according to the actual length of the tool rod body, or the tool rod body is connected to the outside by gluing or injection molding. See attached for specific structure Figure 1-8 .

[0039] In this embodiment, the reinforced limit assembly includes a metal pipe 3 and a connecting pipe 11 . One end of the metal tube 3 is set outside the inner sleeve 8 ; the inner sleeve 8 w...

Embodiment 2

[0044] The connecting structure is used for connecting the rod body with the tool head. The outer surface of the outer sleeve is a tapered structure matching the connecting pants of the tool head, see attached Figure 9-15 .

[0045] In this embodiment, the reinforced limiting assembly includes a metal tube 3 , a fiber tube 6 , a limiting sleeve 4 and a positioning pin 7 . The metal 3 tube is a hollow cylindrical tube, one end of which is sleeved in the inner sleeve 8, and the outside of the other end is sleeved with the fiber tube 6; In this embodiment, the fiber tube and the spacer sleeve are separate structures. Preferably, the outer wall of the fiber tube and the inner wall of the spacer sleeve are provided with matching spacer teeth; the two can also be an integral structure of injection molding. The limit sleeve 4 is used in conjunction with the fastening sleeve 5, and the end of the fastening sleeve is provided with an annular end face, which acts as a limit to the li...

Abstract

A quick assembly type tool rod body connecting structure comprises an outer casing pipe, an inner casing pipe, a reinforcing limiting assembly and a fastening sleeve. The inner casing pipe is sleeved with the outer casing pipe, the reinforcing limiting assembly for reinforcing the connecting and limiting functions is arranged between the inner casing pipe and the fastening sleeve, and the fastening sleeve is in threaded connection with the outer casing pipe. The connecting structure is suitable for quick connection and installation between tool rods and tool heads and between the tool rods, rod body components are connected and assembled through simple thread screwing, operation is easy, convenient and quick, on the premise that quick disassembly and assembly are achieved, reinforcing pieces such as a metal pipe are additionally arranged, and the strength and stability of a connecting part are guaranteed.

Description

technical field [0001] The invention relates to a rod body connection structure, in particular to a quick assembly tool rod body connection structure suitable for hand tools. Background technique [0002] At present, there are many ways to connect the rods of hand tools. In order to facilitate storage and transportation, telescopic or detachable and assembleable rods are more and more popular among consumers. The tool rods occupy a small area and are easy to assemble and replace. [0003] However, among the many tool rods that can be assembled, in order to ensure their stability and use strength, the connection between most of the rods needs to be connected and fixed by additional connecting parts such as bolts. During the assembly process, the bolts are screwed and other additional connectors also need to be operated by the user on the spot. If the user is a woman or a group with less strength, this connection method still cannot achieve the purposes of quick installation ...
