[0020] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0021] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0022] like Figures 1-2 As shown, this application provides a connecting structure for an eyebrow trimmer cover, including a main rod 1, which is through-connected, and blade rods 3 are inserted into both ends of the main rod 1. Buckles 32 are pressed onto the blade rods 3, and blades 33 are clamped between the buckles 32 and the blade rods 3.

[0023] The connection method between the aforementioned fastener 32 and the tool holder 3 is existing technology. For its specific structure and principle, please refer to the existing technology. It will not be elaborated on here.

[0024] Meanwhile, a cover 2 is fitted on the tool holder 3. The cover 2 is used to close and protect the blade 33. A retaining platform 21 is provided on the inner ring of the cover 2. A step 31 that matches the retaining platform 21 is provided on the tool holder 3. When the cover 2 needs to be fitted onto the tool holder 3, the retaining platform 21 is squeezed by the step 31. The cover 2 is then fixed onto the tool holder 3 by the cooperation of the retaining platform 21 and the step 31.

[0025] like Figures 2-3 As shown, receiving grooves 11 are provided on both ends of the main rod 1. Hook lock units 4 are provided on the receiving grooves 11. The hook lock units 4 include pressure plates 41 hinged in the receiving grooves 11. The bottom surface of the receiving grooves 11 is inclined to limit the rotation of the pressure plates 41. A spring 42 is provided at the bottom left end of the pressure plates 41. The two ends of the spring 42 are fixedly connected to the pressure plates 41 and the bottom surface of the receiving grooves 11. The spring 42 is in a contracted state and always applies elastic force to the pressure plates 41. A pressing end 411 is provided at the upper left end of the pressure plates 41. The pressing end 411 has horizontal grooves for easy contact. The pressing end 411 is located directly above the spring 42.

[0026] When pressure is applied to the pressing end 411, the pressure plate 41 rotates under the action of external force, and the right end of the pressure plate 41 is lifted, and the end of the pressure plate 41 squeezes the spring 42. When the external force applied to the pressing end 411 disappears, the pressure plate 41 returns to its original position under the action of the spring 42.

[0027] The right end of the pressure plate 41 is provided with a hook lock end 412, which is located at the cover 2. The cover 2 is provided with a hook groove (not shown in the figure) that is adapted to the hook lock end 412. The hook lock end 412 is adapted to cooperate with the hook groove to hook the cover 2 for secondary fixation. The end of the hook lock end 412 is provided with a bevel for contacting the cover 2.

[0028] During the process of sleeve 2 being fitted onto the knife bar 3, the outer wall of sleeve 2 abuts against the inclined surface of hook locking end 412 and squeezes hook locking end 412, causing pressure plate 41 to rotate and squeeze spring 42, and hook locking end 412 to lift up and move closer to hook groove of sleeve 2. When sleeve 2 is completely fitted onto knife bar 3, through the elastic force of spring 42, hook locking end 412 hooks into hook groove on sleeve 2, thereby achieving the purpose of secondary limiting and locking of sleeve 2;

[0029] When it is necessary to remove the cover 2 from the knife bar 3, first apply external force to the pressing end 411, so that the end of the pressure plate 41 rotates under the force, and under the rotation of the pressure plate 41, the hook locking end 412 is lifted and disengaged from the hook groove. Then, the cover 2 is moved so that the cover 2 is disengaged from the knife bar 3. At this time, the force applied to the pressing end 411 is removed, and under the action of the spring 42, the pressure plate 41 is reset.

[0030] In summary, through the cooperation of the locking platform 21 and the step 31, the cover 2 is suitable for being fixed on the knife bar 3, achieving the purpose of fixing the cover 2 at one time. Furthermore, under the elastic force of the spring 42 applied to the pressure plate 41, the hook locking end 412 is suitable for hooking into the hook groove of the cover 2, achieving secondary limiting and locking of the cover 2, thereby solving the problem of the cover 2 being prone to wear and falling off after long-term use.

[0031] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations are possible for those skilled in the art. Any improvements and modifications made within the spirit and principles of this application, without departing from its principles, should also be considered within the scope of protection of this application.
