Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of garden tools, in particular to a hinged locking structure of a connecting rod of a garden tool. BACKGROUND

[0002] In the existing garden tools, such as a grass trimmer or a brush cutter, a long connecting rod is arranged between the handle and the working part. Although this arrangement is convenient for use, it is not very convenient to store when not in use because of the large space occupied.

[0003] Therefore, a folding device for a garden tool is provided in the announcement No. CN205260514U, which comprises a first fixed head and a second fixed head. The first fixed head and the second fixed head are provided with a joint for fixing a connecting rod at one end. The first fixed head and the second fixed head are hingedly connected at the other end. The first fixed head and the second fixed head are provided with a locking assembly at the upper part of the other end. The folding device is applied to the garden tool, so that the garden tool is convenient to store. The bolt is locked by a nut after passing through the first lug, the second lug and the third lug. Firstly, if the pre-installed nut is not an integral structure, the assembly is more troublesome. If the pre-installed nut is a split structure, it is easy to fall off after being separated from the thread cooperation. Secondly, the above three lugs are simultaneously inserted into the inner hole by the bolt. A certain amount of space is reserved to ensure that the bolt can smoothly pass through. Therefore, the lug located in the middle may collide with the bolt under the high-frequency vibration of the garden tool, causing abnormal noise. In addition, under long-term vibration, the inner wall of the connecting hole of the middle lug will be worn, resulting in unstable connection. How to solve the above problems is the purpose of the present application.

[0004] The above content is only used to assist in understanding the technical solutions of the present application, and does not represent the acknowledgement of the above content as the closest prior art to the present application. SUMMARY

[0005] Therefore, the present application provides a hinged locking structure of a connecting rod of a garden tool to solve one of the above technical problems.

[0006] The technical scheme adopted by the application to solve its technical problems is a hinged locking structure of a garden tool connecting rod, comprising: a first fixed head and a second fixed head, one side of the first fixed head is provided with a first rod, one side of the second fixed head is provided with a second rod, the first fixed head and the second fixed head are hinged to each other on one side of the other end of the first rod and the second rod, the top end of the first fixed head and the second fixed head is respectively provided with a first connecting lug and a second connecting lug, a rotating handle is arranged between the first connecting lug and the second connecting lug, a partial thread is arranged in the first connecting lug, a full thread is arranged in the second connecting lug, and the rotating handle can be in a locked state and an unlocked state through thread cooperation with the first connecting lug and the second connecting lug.

[0007] In some embodiments, the rotating handle comprises a handle, a connecting column fixedly arranged at one end of the handle, a first thread arranged at the end region of the connecting column, and an abutting portion arranged at the other end of the connecting column.

[0008] In some embodiments, a second thread is further arranged on the connecting column.

[0009] In some embodiments, a connecting hole is arranged on the first connecting lug, the connecting hole comprises a thread segment and a transition segment arranged on both sides of the thread segment, the thread segment is used for mutual cooperation with the first thread and the second thread, and the diameter of the transition segment is greater than that of the thread segment.

[0010] In some embodiments, a threaded hole is arranged in the second connecting lug, and the threaded hole is used for cooperation with the first thread.

[0011] The application has the beneficial effects that when the first rod and the second rod need to be fixed, the connecting column is only needed to be screwed into the second connecting lug by rotating the rotating handle, at this time, the rotating handle is very stable in connection with the first rod and the second rod through the first thread and the second thread, and when the first rod and the second rod need to be stored, the first thread is screwed out of the threaded hole and cooperates with the thread segment, at this time, the connecting column is no longer between the first connecting lug and the second connecting lug, the first fixed head and the second fixed head can be rotated, which is very convenient and does not need to store the rotating handle additionally.
