Description

Technical Field

[0001] The utility model relates to the technical field of hair clippers, in particular to a hair clipper limiting comb. Background Art

[0002] An electric hair clipper is a tool for trimming hair, and a limiting comb is an auxiliary tool designed for convenient hair cutting. The limiting comb has a comb-shaped member covering the blade part of the electric hair clipper, and forms a fixed-length interval between the blade part and a person's skin, which can help a barber control the hair length and keep it consistent. At the same time, it can also prevent the cutter head from hurting the scalp.

[0003] Chinese patent document CN203993929U discloses a new type of baby hair clipper, which includes a cutter head assembly and a main body; the main body includes an upper cover, a lower cover, a motor, an eccentric vibration assembly, etc. arranged between the upper cover and the lower cover. A detachable limiting comb is arranged outside the cutter head assembly. When in use, the socket feet on both sides of the limiting comb are clamped at corresponding positions on the lower cover. In the above technical solution, the elastic force generated when the limiting comb undergoes elastic deformation is mainly used to make the socket feet and the corresponding positions be clamped and fixed. However, the limiting comb is generally made of plastic material. As the disassembly and assembly time and the number of disassembly and assembly times of the limiting comb increase, the elastic force of the limiting comb itself will gradually weaken, resulting in the loosening of the clamping between the socket feet and the corresponding positions; at the same time, due to the inevitable wear of the socket feet during the disassembly and assembly process, the clamping between the socket feet and the corresponding positions fails, so that the limiting comb is likely to fall off the hair clipper, and the limiting comb falling on the ground may cause the limiting comb to deform or be damaged, and then lead to poor assembly with the cutter head, affecting the hair cutting effect.

[0004] Therefore, it is necessary to provide a hair clipper limiting comb whose fixing effect with the hair clipper is not affected by the number of disassembly and assembly times, so that it can maintain a long-term firm fixation with the hair clipper. Summary of the Utility Model

[0005] Therefore, the technical problem to be solved by the utility model is to overcome the technical defect that in the prior art, the limiting comb and the hair clipper generally use the elastic force generated when the limiting comb undergoes elastic deformation for clamping and fixing. As the disassembly and assembly time and the number of disassembly and assembly times of the limiting comb increase, the elastic force of the limiting comb weakens and the clamping structure is often worn, resulting in poor fixation between the limiting comb and the hair clipper, and then affecting the hair cutting effect. Thus, a hair clipper limiting comb whose fixing effect with the hair clipper is not affected by the number of disassembly and assembly times, so that it can maintain a long-term firm fixation with the hair clipper is provided.

[0054] The following will detail this application with reference to the drawings and in combination with embodiments.

[0055] This embodiment provides a hair clipper limiting comb, as Figures 1-6 shown, including a limiting comb body 1, a mounting base 2, a locking rod 3 and an elastic member 4; an installation cavity 100 is arranged inside the limiting comb body 1, and an opening 110 communicating with the installation cavity 100 is arranged on the limiting comb body 1; the mounting base 2 is arranged inside the installation cavity 100 and is fixedly connected to the limiting comb body 1 through a first installation structure; one end of the locking rod 3 passes through the opening 110 and is movably installed inside the installation cavity 100, and the other end is located outside the installation cavity 100 and is provided with a locking hook 31; the elastic member 4 is installed between one end of the locking rod 3 and the mounting base 2 and is used for continuously applying a force to one end of the locking rod 3 to make the locking hook 31 buckle to one side; the locking hook 31 can deflect to the other side against the force of the elastic member 4 under the action of an external force, and can reset under the action of the elastic member 4 after the external force disappears.

[0056] The hair clipper limiting comb of this embodiment can be used in cooperation with a hair clipper having the Figure 7 structure shown in.
