Description

Staggered multi-layer trimming head applied to electric hair clippers

This creative department belongs to the field of hair cutting equipment, especially about a staggered multi-layer trim head applied to electric hair clippers. It has an adjustable movable blade design that can be adjusted to a single cutting track or multiple cutting tracks. Those who change the original operating habits to quickly complete various haircut effects.

Generally, hair stylist will use special haircut tools to cut hair for customers. These special haircut tools generally include special scissors and electric hair clippers, etc., and use different haircut tools for trimming according to the needs of hair stylist and customers.

However, scissors for haircuts are designed with sharp blades in order to achieve a neat and trimmed effect. Therefore, special attention should be paid to the safety of use and storage. However, the electric hair clipper uses an electric motor combined with cross-operating blades to cut hair quickly. It is mainly used for trimming a large number of hairs. Therefore, when most hair stylist performs haircut, they use both methods in parallel. However, when using the above two kinds of haircut tools, the hair stylist uses hands to grab or use a comb to comb the amount of hair to be cut before cutting. The blades of these scissors and electric hair clippers are all used Side-to-side cutting operation, using one-way outward squeezing and cutting the hair, not only the incision is inclined and uneven, but also when performing layered haircuts, it usually takes more time to use layered haircuts. Scissors.

Take an electric hair clipper as an example. It has a main body, a motor and a power source are arranged inside the main body, and a trimming head is installed at the front end of the main body. After the trimming head is powered on with the motor, It can form a cutting track. Therefore, the cutting track formed by the trim head is used to cut the hair during the operation. Because the cutting speed of the electric hair clipper is extremely fast, it is mostly used in hair clippers. , That is, a large area of hair cutting. During its operation, the trimming head is usually equipped with a length-controlled baffle, one side of which is used to lean against the scalp, using the formed between the baffle and the trimming head Space the distance, and quickly adjust its trim length. The reason is that this kind of electric hair clippers can only trim large areas of hair. When cutting a layered hairstyle, you still need to manually operate special layered trimming scissors, using the serrated structure of the two blades to make When cutting, the effect of different levels is produced. It is impossible to quickly trim and control the length of the trimming level, so it is necessary to improve it.

For this reason, this creation has accumulated many years of practical experience in the design of hairdressing tools and developed a staggered multi-layer trim head structure that can be applied to electric hair clippers. Its adjustable movable blade design can be adjusted to a single clipper during cutting. Cut trajectory or multiple splicing trajectories to quickly complete various hair cutting effects without changing the original operating habits.

In view of this, one purpose of this creation is to provide a staggered multi-layered trimming head for electric hair clippers, so that a movable knife set is equipped with a first movable knife and at least one second movable knife. An adjustment lever connected with the second movable knife forms an adjustable movable knife board design, which can be quickly adjusted to a single cutting track or multiple splicing tracks during cutting, without changing the original operating habits Quickly complete various different hair cutting effects, greatly improving the efficiency and quality of hair cutting.
