Description

Technical Field

[0001] This utility model relates to the field of agricultural tool technology, specifically to a detachable structure for connecting the tool head and the operating handle. Background Technology

[0002] Tools come in a wide variety of forms, one of which is a tool assembled from an operating handle and a tool head, such as a hook body connected to the front end of the operating handle or a cutting tool connected to the front end of the operating handle. Currently, the connection between the operating handle and the tool head is mostly direct welding. If the operating handle or tool head is damaged, the entire tool is scrapped, or the damaged part is ground off and re-welded, making repairs cumbersome.

[0003] Alternatively, it can be a simple matter of drilling holes in the handle and tool head and connecting them with bolts and nuts. However, replacement requires disassembling the bolts and nuts, which is cumbersome and lacks speed. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the defects of the above-mentioned technology and provide a detachable structure for connecting the tool head and the operating handle.

[0005] A detachable structure for connecting a tool head and an operating handle includes a first connecting body fixedly connected to the tool head, a second connecting body fixedly connected to the operating handle, and a locking sleeve. The first connecting body includes a cylindrical intermediate body, one end of which is provided with a connecting portion for docking with the tool head, and the other end is provided with a polygonal column. The cylindrical intermediate body is provided with external threads on its exterior, and the diameter of the cylindrical intermediate body is greater than the maximum dimension of the cross-section of the polygonal column along its vertical axis.

[0006] The second connecting body includes a cylindrical tube with a polygonal hole inside that mates with a polygonal column. One end of the cylindrical tube is connected to an operating handle, and the other end is provided with a limiting plate with an outer diameter larger than the outer diameter of the cylindrical tube. The limiting plate is smaller than the outer diameter of the cylindrical intermediate body.

[0007] The locking sleeve includes a sleeve, the inner wall of which is provided with an internal thread that mates with the external thread, a blocking plate at one end of the sleeve, and a through hole through which a cylindrical tube can pass. The limiting plate of the second connecting body is located inside the sleeve.

[0008] Furthermore, the polygonal column is a hexagonal column, and the polygonal hole is a hexagonal hole.

[0009] Furthermore, the first connector is fixed to the tool head by welding or screws.

[0010] Furthermore, the second connector is fixed to the operating handle by welding or screws.

[0011] Advantages of this utility model: This utility model has a reasonable structure and is quick and easy to assemble and disassemble. It achieves quick connection and separation by locking and loosening the external thread on the cylindrical intermediate body of the locking sleeve and the first connecting body. The limiting effect of the polygonal column of the first connecting body and the polygonal hole of the second connecting body prevents the tool head and the operating rod from rotating with each other.

[0020] A detachable structure for connecting a tool head and an operating handle includes a first connecting body 1 fixedly connected to the tool head, a second connecting body 2 fixedly connected to the operating handle, and a locking sleeve 3. The first connecting body 1 includes a cylindrical intermediate body 101. One end of the cylindrical intermediate body 101 is provided with a connecting part 102 for docking with the tool head, and the other end is provided with a polygonal column 103. The cylindrical intermediate body 101 is provided with external threads 104. The diameter of the cylindrical intermediate body 101 is larger than the maximum dimension of the cross section of the polygonal column 103 perpendicular to the axis.

[0021] The second connecting body 2 includes a cylindrical tube 201, which has a polygonal hole 202 that mates with the polygonal column 103. One end of the cylindrical tube 201 is connected to the operating handle, and the other end is provided with a limiting plate 203 with an outer diameter larger than the outer diameter of the cylindrical tube 201. The outer diameter of the limiting plate 203 is smaller than the outer diameter of the cylindrical intermediate body 101.

[0022] The locking sleeve 3 includes a sleeve 301. The inner wall of the sleeve 301 is provided with an internal thread 302 that mates with the external thread 104. One end of the sleeve 301 is provided with a blocking plate 303. The blocking plate 303 is provided with a through hole 304 through which the cylindrical tube 201 can pass. The limiting plate 203 of the second connecting body 2 is located inside the sleeve 301.

[0027] Example 1

[0028] like Figure 2 As shown, a through hole is provided at the connecting part 102 of the first connecting body 1, and it is fixedly connected to the tool head 1-1 by bolts and nuts. A through hole is provided at the end of the cylindrical tube 201 of the second connecting body 2 away from the limiting plate 203, and it is fixedly connected to the operating handle 1-2 by bolts and nuts. Before the second connecting body 2 is connected to the operating handle 1-2, the locking sleeve 3 needs to be put on the second connecting body 2.

[0029] When the tool head 1-1 and the operating handle 1-2 are connected by the structure of this utility model, the polygonal column 103 is inserted into the polygonal hole 202, and the rotating locking sleeve 3 is screwed onto the cylindrical intermediate body 101 through the internal thread 302 and the external thread 104 to complete the assembly, thereby realizing the connection between the tool head 1-1 and the operating handle 1-2, and there will be no rotation between the tool head 1-1 and the operating handle 1-2.
