Description

Technical Field

[0001] This utility model relates to a garden tool with a quick-change tool head, belonging to the field of agricultural or garden tool technology. Background Technology

[0002] Currently, during agricultural or gardening operations, it is often necessary to carry a large number of different types of tools, making outdoor use quite inconvenient. Therefore, a gardening tool or agricultural implement with interchangeable tool heads has been developed. This allows users to carry only a handheld tool body and a matching tool bag containing multiple different types of tools, significantly improving ease of use. However, existing gardening tools or implements with interchangeable tool heads rely on bolts or clamps for replacement, which is cumbersome and inconvenient, further impacting the efficiency of agricultural or gardening operations. Utility Model Content

[0003] This invention overcomes the shortcomings of the existing technology and provides a garden tool with a quick-change tool head, which meets the high-intensity work requirements of garden tool use and reduces the cumbersome operation steps of traditional tool changing. Users can change tools with simple operation.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a garden tool with a quick-change tool head, comprising a main shaft, a replaceable tool head, a connecting rod, and a rotating handle. One end of the main shaft has an assembly interface, and a ring-shaped baffle is provided at the assembly interface. The replaceable tool head is assembled to the assembly interface of the main shaft via the connecting rod and the rotating handle. The connecting rod is connected to the assembly interface of the main shaft, and the rotating handle is sleeved at the connection between the connecting rod and the main shaft. The end of the rotating handle has an external thread, and the overall thread has a certain taper. The inner side of the end of the replaceable tool head has an internal thread. The rotating handle and the replaceable tool head are connected together by threads.

[0005] Furthermore, one end of the connecting rod is provided with a hexagonal post, which fits into the tail of the replaceable tool head.

[0006] Furthermore, the bottom end of the hexagonal column of the connecting rod is provided with a protruding annular plate, and the inner side of the end of the replaceable tool head is provided with a first limiting step corresponding to the protruding annular plate, and the protruding annular plate can match and abut against the first limiting step.

[0007] Furthermore, after the external thread end of the rotating handle is screwed into place inside the replaceable tool head, it presses against the raised annular plate at the bottom of the hexagonal column.

[0008] Furthermore, a second limiting step is provided at the end of the connecting rod away from the hexagonal column. The second limiting step can press against the annular step on the inner side of the main rod to prevent the connecting rod from sliding.

[0009] Furthermore, the end of the rotating handle away from the external thread is pressed against the annular baffle of the main rod.

[0010] Compared with existing technologies, this invention offers the following advantages: It utilizes a screwless fixing method to achieve quick replacement of required tool parts. The tightening effect of the threads meets the high-intensity operational needs of garden tools and reduces the cumbersome steps involved in traditional tool replacement. This significantly reduces the need to carry multiple different tools under various complex working conditions, greatly minimizing the overall space required. Users can easily replace tools through simple operations. Attached Figure Description

[0017] The present invention will be further described below with reference to specific embodiments.

[0018] like Figures 1-4This utility model relates to a garden tool with a quick-change tool head, characterized by being a handheld device that can be changed to the type of tool needed. The device includes a main rod 1, a replaceable tool head 2, a connecting rod 3, and a rotating handle 4. One end of the main rod 1 has an assembly interface with a ring-shaped baffle. The replaceable tool head 2 is assembled to the main rod 1 via the connecting rod 3 and the rotating handle 4 at the assembly interface. The connecting rod 3 is connected to the main rod 1 at the assembly interface, and one end of the connecting rod 3 has a hexagonal post 5 that fits into the tail of the replaceable tool head 2. The bottom end of the hexagonal post 5 of the connecting rod 3 has a protruding ring plate. The inner side of the end of the replaceable tool head 2, corresponding to the protruding ring plate, has a first limiting step 6. The protruding ring plate abuts against the first limiting step 6. After the external thread end of the rotating handle 4 is screwed into place inside the replaceable tool head 2, it presses against the protruding ring plate at the bottom end of the hexagonal post 5. A second limiting step 7 is provided at the end of the connecting rod 3 away from the hexagonal column 5. The second limiting step 7 can match and press against the annular step on the inner side of the main rod 1 to prevent the connecting rod 3 from sliding. The rotating handle 4 is sleeved at the connection between the connecting rod 3 and the main rod 1. The end of the rotating handle 4 is provided with an external thread, and the overall thread has a certain taper. The inner side of the end of the replaceable tool head 2 is provided with an internal thread. The rotating handle 4 and the replaceable tool head 2 are connected together by threads. The end of the rotating handle 4 away from the external thread is pressed against the annular baffle of the main rod 1.

[0019] This utility model has an assembly interface at one end of its main shaft 1, which has a ring-shaped baffle. The replaceable tool head 2 is assembled at the assembly interface of the main shaft 1 via a connecting rod 3 and a rotating handle 4. The connecting rod 3 is placed at the assembly interface, and the rotating handle 4 is fitted onto its outer side. One end of the rotating handle has a threaded opening, and the overall thread has a slight taper. One end of the connecting rod 3 has a hexagonal post 5 that fits into the tail of the replaceable tool head 2, and is assembled and fitted at a first limiting step 6. The tail end of the connecting rod 3 also has a second limiting step 7 that fits into the main shaft, preventing the connecting rod 3 from sliding in the middle. After the fitting is completed, rotating the rotating handle 4 achieves a locking effect. Thus, when using garden tools, the force applied to the replaceable tool head 2 will not directly act on the rotating and fixed connection, thereby preventing loosening during use.

[0020] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
