Quick connecting structure of tool handle

Abstract

The invention discloses a quick connecting structure of a tool handle, which is characterized in that a connecting piece is fixedly arranged at the front end part of the handle, outer side edge clamping sawteeth are arranged on the two side edges of the connecting piece, and inner side edge clamping sawteeth are arranged on the two side edges in a mounting hole of a tool head; the outer side edge clamping sawteeth are tightly meshed with the inner side edge clamping sawteeth; after the scheme is adopted, the connecting piece is meshed with the opposite sawteeth in the mounting hole of the tool head, so that the handle can be quickly mounted, and the handle cannot be loosened after being mounted.

Description

Technical Field

[0001] The invention relates to a connection structure between a tool and a handle. Background Art

[0002] Traditional hand tools such as shovels, hoes, rakes, etc. have separate handles and tool heads. The handle needs to be knocked hard to make it fit tightly onto the tool head, and nails are also needed to assist in fixing it. However, after long-term use, the handle will still become loose. Summary of the invention

[0003] The object of the present invention is to provide a tool handle connection structure which is easy to install and not easy to loosen.

[0004] To achieve the above-mentioned purpose, the tool handle of the present invention has a quick connection structure, wherein the handle is inserted into the mounting hole of the tool head, wherein a connecting piece is fixedly arranged at the front end of the handle, and outer side clamping serrations are arranged on both sides of the connecting piece, and inner side clamping serrations are arranged on both sides of the mounting hole of the tool head. When the handle is installed in the mounting hole of the tool head, the aforementioned outer side clamping serrations are tightly engaged with the inner side clamping serrations.

[0005] The connecting piece is in the shape of an arrow, the outer side clamping serrations are arranged on the outer sides of the two elastic wings, and a plurality of pressing protrusions are arranged on the middle connecting rod part.

[0006] An elastic mounting seat matched with the outer shape of the connecting piece is arranged in the mounting hole of the tool head, and inner side clamping serrations are arranged on both sides of the elastic clamping sleeve.

[0007] After adopting the above scheme, the present invention utilizes the engagement between the connecting piece and the relative serrations in the tool head mounting hole, so that the handle can be quickly installed and will not become loose after installation. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] In order to explain the technical content, structural features, achieved objectives and effects of the present invention in detail, the following is a detailed description in conjunction with the implementation methods and the accompanying drawings.

[0014] See also Figure 1 as well as Figure 2 , 3 The quick connection structure of the tool handle of the present invention is mainly used for connecting the handles of household tools such as shovels, rakes, hoes, hammers, and hammers with tool heads, and includes a tool head 1, a connector 2 and a handle 3. The handle can be tightly inserted into the mounting hole of the tool head. Two mounting screw holes 23 are provided at both ends of the connector 2. The connector 2 is screwed to the handle head with two screws. A cavity 12 for inserting the mounting hole is provided in the mounting hole of the tool head. A "V"-shaped elastic mounting seat 11 is clamped in the aforementioned cavity 12, and inner side edge clamping serrations 111 are respectively provided on the two inner side walls of the elastic mounting seat 11. The connector 2 is composed of an intermediate connecting rod portion 21 and two elastic wings 22 to form an arrow shape. The outer sides of the two elastic wings 22 are provided with outer side edge clamping serrations 221. When the connecting piece 2 is inserted into the cavity 12 of the tool head mounting hole, the outer side clamping serrations 221 engage with the inner side clamping serrations 111 so that the connecting piece 2 cannot be withdrawn. In order to maintain the tight connection between the two clamping serrations, the connecting piece 2 is provided with a transverse pressing protrusion 211 on the middle connecting rod portion 21 to prevent the elastic wing portion 22 from being retracted.

[0015] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent shape or structural transformation made using the contents of the present invention's specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
