Description

Technical Field

[0001] The utility model relates to a connecting structure between a tool and a handle. Background Art

[0002] For traditional hand tools such as shovels, hoes, rakes, etc., the tool handle and the tool head are separate parts. It is necessary to forcefully strike the handle to tightly insert it into the tool head, and nails, etc. are also needed to assist in fixing. Although in some cases, a wedge is inserted between the handle and the tool head, the handle will still become loose after long-term use. Another situation is that if the handle is damaged, it is not convenient to replace the handle. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a connecting structure for a tool handle that is convenient to install, not easy to loosen, and easy to replace.

[0004] To achieve the above object, the utility model provides a quick-release tool handle quick-connecting structure. The handle is inserted into the installation hole of the tool head. Among them, a connecting piece is fixedly arranged at the front end of the handle, and an installation seat adapted to the outer shape of the connecting piece is arranged in the installation hole of the tool head. An opening is formed in the installation seat, and a clamping protrusion that can be clamped in the aforementioned opening is elastically arranged above the connecting piece.

[0005] The main body of the connecting piece is fixedly connected to the handle. An elastic tail that tilts upward is arranged at the rear end of the main body. The end of the elastic tail is a pressing part, and the clamping protrusion is arranged in the middle section of the elastic tail.

[0006] An elastic damping connecting part that protrudes outward is arranged in the middle of the main body of the connecting piece.

[0007] The elastic damping connecting part is two outwardly extending arc surfaces.

[0008] After adopting the above scheme, the utility model utilizes the close cooperation of the clamping protrusion and the opening arranged oppositely in the installation hole of the tool head and the elastic damping connecting part and the installation seat, can quickly realize the installation of the handle, will not loosen after installation, and the pressing part of the elastic tail of the connecting piece can realize the separation of the clamping protrusion from the installation seat, so as to take out the handle from the installation hole.

[0014] To describe in detail the technical content, structural features, achieved purposes and effects of the present utility model, the following is a detailed description in conjunction with the implementation modes and with reference to the drawings.

[0015] Please refer to Figure 1 and Figure 2 、 3 A quick-disassembly tool handle quick connection structure of the present utility model is mainly applied to the connection between the handles of agricultural tools such as shovels, rakes, hoes, hammers, mallets, etc. and the tool heads, and includes a tool head 1, a connecting piece 2 and a handle 3. The handle can be closely inserted into the mounting hole 11 of the tool head 1. There are two mounting screw holes 24 on the body of the connecting piece 2, and the connecting piece 2 is screwed to the head of the handle 3 with two screws. There is a cavity for inserting the connecting piece 2 in the mounting hole 11 of the tool head 1, and an opening 12 is provided on the cavity. When the connecting piece 2 is inserted into the cavity 12 of the tool head mounting hole, the clamping projection 22 provided on the elastic tail of the connecting piece that warps up is clamped into the opening 12 so that the connecting piece 2 cannot be withdrawn. In order to maintain the close connection between the connecting piece and the tool head, there are two outward-extending elastic damping connecting parts 21 with two arc surfaces in the middle of the body of the connecting piece 2.

[0016] During installation, screw the connecting piece 2 onto the handle 3, insert the handle head into the tool head and tap the handle. The elastic damping connecting part 21 is closely connected to the mounting hole, and the clamping projection 22 is clamped into the opening 12, so that the handle is installed on the tool head. When the handle or the tool head is damaged and needs to be replaced, press down the pressing part 23 at the elastic tail of the connecting piece 2, the clamping projection 22 disengages from the opening 12, and the handle can be removed from the mounting hole of the tool head.

[0017] The above are only the embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent shape or structure transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present utility model.
