[0017] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are provided solely for the purpose of clearly illustrating the technical solution of the present invention, offering numerous specific details to provide a more thorough understanding. However, those skilled in the art will recognize that the present invention can be implemented without one or more of these details. In these examples, to avoid confusion with the present invention, some technical features known in the art have not been described.

[0018] It should be understood that the present invention can be implemented in different forms and should not be construed as being limited to the embodiments set forth herein. Therefore, these embodiments are merely examples and should not be used to limit the scope of protection of the present invention.

[0019] Additionally, it should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0020] See Figures 1 to 3 A multi-specification compatible grass trimmer head includes a housing 1, which has a peripherally protruding threading wall and at least one outlet hole 2 for grass trimming line to pass through. The housing 1 is provided with multiple winding units of various specifications. Each winding unit of various specifications includes a winding hole 4 located on one side of the outlet hole 2 on the threading wall or located on the body of the housing 1. In use, one end of the grass trimming line is secured in the winding hole 4, and the other end passes through the outlet hole 2 after turning to fix the grass trimming line.

[0021] Continue to refer to the following during implementation. Figure 2 For example, one end of a 4.5mm trimmer line A is passed through the winding hole 4 corresponding to the 4.5mm specification in the winding unit, and the other end is passed through the exit hole 2 on one side of the winding hole 4. The trimmer line A is then straightened through the exit hole 2. Alternatively, trimmer line A can be passed through the threading wall through the exit hole 2, and then the end can be inserted into the winding hole 4 corresponding to the 4.5mm specification. The trimmer line A protruding from the exit hole 2 can then be straightened. Similarly, for a 2.4mm trimmer line B, the end can be inserted into the corresponding size winding hole 4 using the same method.

[0022] In addition, during implementation, the housing 1 is disc-shaped, and the wire outlet holes 2 are all located on the protruding wire-passing walls around the disc-shaped housing 1. Multiple winding holes 4 of different sizes are provided on the wire-passing walls between the wire outlet holes. These winding holes 4 can be arranged from small to large sizes, with the direction of proximity to the wire outlet holes outwards. This facilitates direct insertion by the user during use. Of course, without other specifications, the corresponding winding hole can also be found by pulling the end of the grass-cutting line and corresponding to each winding hole 4.

[0023] Furthermore, as an improvement to this utility model, the cross-section of the threading wall is trapezoidal; the outlet hole 2 is located above the winding hole 4; after the grass trimming line is fixed, a bending structure is formed between the outlet hole 2 and the winding hole 4, so that the grass trimming line is secured to the side of the winding hole 4 and presses against the edge of the winding hole 4, and the other end of the grass trimming line presses against the edge of the outlet hole 2.

[0024] During implementation, the bending structure formed by the outlet hole 2 and the winding hole 4 fully utilizes the elasticity of the grass trimming line itself after bending to convert it into the frictional force of the corresponding winding hole 4 wall, thus achieving the fixed installation of the grass trimming line.

[0025] Furthermore, as an improvement to this utility model, the cross-sectional area of ​​the outlet hole 2 is greater than or equal to the cross-sectional area of ​​the winding hole 4.

[0026] In practice, the above configuration allows the outlet hole 2 to pass through all sizes of trimming lines.

[0027] Furthermore, as an improvement to this utility model, the winding unit also includes a specification mark 3; the specification mark 3 is disposed on both sides of the wire-passing wall above the wire outlet hole 2; the winding hole 4 is disposed on the wire-passing wall corresponding to the specification mark 3 below.

[0028] During implementation, the specification marking 3 allows users to quickly select the appropriate winding hole 4 for the corresponding size of the trimming line when installing it, thus improving the efficiency of trimming line replacement.

[0029] Furthermore, as an improvement to this utility model, the winding unit further includes an indicator mark 5; the indicator mark 5 is disposed on the outer surface of the wire-passing wall between the winding hole 4 and the specification mark 3.

[0030] During implementation, indicator 5 makes it easier to see the winding hole 4 and specification indicator 3.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features.
