Description

Technical Field

[0001] The utility model relates to a sickle which can prevent a cutter head from loosening and belongs to the field of agricultural tools. Background Art

[0002] A sickle, commonly known as a cutting knife, is crescent-shaped and consists of a blade and a wooden handle. Some blades have small serrations. It is generally used to harvest wheat, rice, etc. and is widely used in rural areas. The sickles commonly used on the market currently have a blade head and a handle that are often fixed with bolts. In view of this, a new multifunctional tree felling tool is disclosed in the patent document with application number 201820628822.8. When assembling the blade head and the handle of the sickle in the prior art, the blade head and the handle are fixed by four fixing bolts (5). The four fixing bolts (5) need to be tightened separately, so the assembly process is relatively troublesome. Utility Model Content

[0003] The purpose of the utility model is to overcome the above-mentioned deficiencies in the prior art and to provide a sickle with a reasonable structural design which can prevent the cutter head from loosening.

[0004] The technical solution adopted by the utility model to solve the above-mentioned problem is: the sickle capable of preventing the blade from loosening comprises a blade and a handle, and its structural features are: it also comprises a plastic core and a sleeve, the blade is provided with an insert, the insert is installed on the plastic core, and the plastic core is crimped to one end of the handle through the sleeve; a connecting sleeve is provided at one end of the handle, a limiting groove is provided on the outer wall of the connecting sleeve, the plastic core is inserted in the connecting sleeve, the sleeve is sleeved outside the connecting sleeve, and the sleeve is located in the limiting groove.

[0005] Furthermore, the plastic core comprises a plastic pad and a plastic sleeve, the plastic pad and the plastic sleeve are arranged as an integrated structure, and the outer diameter of the plastic pad is greater than the outer diameter of the plastic sleeve.

[0006] Furthermore, the plastic pad is in contact with the end of the connecting sleeve, and the plastic sleeve is inserted into the connecting sleeve.

[0007] Furthermore, the insert and the blade head are arranged as an integrated structure, and the connecting sleeve and the handle are arranged as an integrated structure.

[0008] Furthermore, the handle is a steel pipe.

[0009] Compared with the prior art, the utility model has the following advantages: the sickle which can prevent the blade head from loosening only needs to fix the blade head and the handle by pressing the sleeve when assembling the blade head and the handle. The assembly and fixation are convenient, and there is no need to fix them with screws. They can be fixed by pressing, and at the same time, the blade head and the handle can be prevented from rotating. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The present invention will be further described in detail below with reference to the accompanying drawings and through examples. The following examples are provided to explain the present invention, but the present invention is not limited to the following examples.

[0019] Example

[0020] See also Figures 1 to 4 As shown, it should be noted that the structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the limiting conditions for the implementation of the utility model, so they have no substantial technical significance. Any modification of the structure, change of the proportional relationship or adjustment of the size, without affecting the effects and purposes that can be achieved by the utility model, should still fall within the scope of the technical content disclosed by the utility model. At the same time, if there are references to terms such as "upper", "lower", "left", "right", "middle" and "one" in this specification, they are only for the convenience of description, and are not used to limit the scope of the implementation of the utility model. The change or adjustment of their relative relationship, without substantially changing the technical content, should also be regarded as the scope of the implementation of the utility model.

[0021] The sickle that can prevent the blade from loosening in this embodiment includes a blade 1, a handle 2, a plastic core 3 and a sleeve 4. The blade 1 is provided with an insert 11, and the insert 11 and the blade 1 are an integrated structure. The insert 11 is installed on the plastic core 3, and the plastic core 3 is crimped to one end of the handle 2 through the sleeve 4. The handle 2 is a steel pipe.

[0022] A connecting sleeve 21 is provided at one end of the handle 2 in this embodiment. The connecting sleeve 21 and the handle 2 are an integrated structure. A limiting groove 22 is provided on the outer wall of the connecting sleeve 21. The plastic core 3 is inserted into the connecting sleeve 21. The sleeve 4 is sleeved outside the connecting sleeve 21, and the sleeve 4 is located in the limiting groove 22.

[0023] The plastic core 3 in this embodiment includes a plastic pad 31 and a plastic sleeve 32. The plastic pad 31 and the plastic sleeve 32 are arranged as an integrated structure. The outer diameter of the plastic pad 31 is larger than the outer diameter of the plastic sleeve 32. The plastic pad 31 contacts the end of the connecting sleeve 21, and the plastic sleeve 32 is inserted into the connecting sleeve 21.

[0024] Specifically, when the cutter head 1 and the handle 2 are assembled, the sleeve 4 is sleeved on the outside of the connecting sleeve 21 and stuck in the limiting groove 22, and the insert 11 is inserted into the plastic core 3, so that the plastic sleeve 32 is inserted into the connecting sleeve 21, and at the same time, the plastic pad 31 contacts the end of the connecting sleeve 21, and the sleeve 4 is pressed by the equipment so that the plastic sleeve 32 and the connecting sleeve 21 are pressed together, thereby completing the assembly of the cutter head 1 and the handle 2.
