Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to a connecting structure of a tool and a handle. BACKGROUND
[0002] The handle and the tool head of traditional hand tools such as a spade, a hoe, a rake and the like are separate, the handle needs to be knocked to be tightly inserted into the tool head, and an iron nail or the like needs to be additionally used for fixing, although a chisel is inserted between the handle and the tool head, but the handle will be loose after long-term use. CONTENT OF THE UTILITY MODEL
[0003] The utility model aims at providing a tool handle connecting structure which is convenient to install and not easy to be loose.
[0004] In order to achieve the above-mentioned purpose, the utility model discloses a quick connecting structure of a tool handle, the handle is inserted into the mounting hole of the tool head, wherein the front end part of the handle is fixedly provided with a connecting piece, the two side edges of the connecting piece are provided with outer side edge clamping sawteeth, the mounting hole of the tool head is provided with inner side edge clamping sawteeth on the two side edges, when the handle is installed in the mounting hole of the tool head, the outer side edge clamping sawteeth and the inner side edge clamping sawteeth are tightly engaged.
[0005] The connecting piece is in the shape of an arrow, the outer side edge clamping sawteeth are arranged on the outer side of the two elastic wing parts, and a plurality of top pressing protrusions are arranged on the middle connecting rod part.
[0006] The mounting hole of the tool head is provided with an elastic mounting seat which is matched with the shape of the connecting piece, and the two side edges of the elastic clamping sleeve are provided with inner side edge clamping sawteeth.
[0007] After the above-mentioned scheme is adopted, the utility model utilizes the engagement between the opposite sawteeth in the connecting piece and the mounting hole of the tool head, so that the installation of the handle can be quickly realized, and the handle will not be loose after installation.

[0013] To make the technical content, structural features, purposes and effects of the utility model clear, the following will be described in detail in combination with the embodiments and the drawings.
[0014] Please refer to Figure 1 and Figure 2 , 3 The utility model relates to a quick connecting structure of tool handle, mainly applied to the connection of the handle and tool head of household tool spade, rake, hoe and hammer, etc., comprising a tool head 1, a connecting piece 2 and a handle 3, the handle can be tightly inserted into the mounting hole of the tool head, the connecting piece 2 is provided with two mounting screw holes 23 at both ends, two screws are used to screw the connecting piece 2 to the handle head, the mounting hole of the tool head is provided with a cavity 12 for inserting the mounting hole, a V-shaped elastic mounting seat 11 is clamped in the aforementioned cavity 12, and the two inner side walls of the elastic mounting seat 11 are respectively provided with inner side edge clamping sawteeth 111. The connecting piece 2 is composed of an arrow-shaped middle connecting rod part 21 and two elastic wing parts 22. The outer side of the two elastic wing parts 22 is provided with an outer side edge clamping sawtooth 221. When the connecting piece 2 is inserted into the cavity 12 of the tool head mounting hole, the outer side edge clamping sawtooth 221 is engaged on the inner side edge clamping sawtooth 111, so that the connecting piece 2 cannot be withdrawn. In order to maintain the tight connection of the two clamping sawteeth, the connecting piece 2 is provided with a transverse pressing protrusion 211 on the middle connecting rod part 21 to prevent the elastic wing part 22 from recovering.
[0015] The above is only the embodiment of the utility model, and does not limit the patent range of the utility model, and any equivalent shape or structural transformation or direct or indirect application in other related technical fields based on the content of the utility model specification and drawings is also included in the patent protection range of the utility model.
