Technical Field

There are two types of electric hair clippers in the market. One is professional and the other is for home use. The later type is generally used between six and twenty-four times per year, that depends on how many people living in the house. The professional type is used around one thousand times per year. Therefore, electric hair clippers designed for domestic used cannot be used in barber shops, because the hair to be cut can blunt the clipper blades easily. My invention can overcome this technical problem, because no matter which type of electric hair clippers can fit into the housing of my invention easily and securely. Background Art

To become a professional barber hairstylist needs a minium of 400 hours in formal training and practice. After graduation, cutting a man s hair in perfection needs between 45 and 75 minutes. With my invention attached to an electric hair clipper and connected to a domestic or workshop vacuum cleaner, an untrained barber can perform as perfect as a newly graduated barber in less than 20 minutes and it is absolutely safe. No shearing is required and no hair clippings fall neither on the body nor on the floor. Disclosure of Invention

No cutting mechanism is built inside the housing: However, most brand named electric hair clippers can be secured easily and safely to the base of the housing. My invention consists of nine parts, namely: 1. Housing (See Fig. 1, 2, 3 and 4); 2. Rubber sleeve (See Fig. 5); 3. Copper fastener (See Fig. 6 and 7); 4a. Single leg spacer #1 (See Fig. 8); 4b. Single leg spacer #2 (See Fig. 9); 5. Duct spacer connector (See Fig. 10, 11 and 12); 6. Duct spacer (See Fig. 13, 14 and 15); 7a. End duct spacer #1 (See Fig. 16, 17 and 18) and 7b. End duct spacer #2 (See Fig. 19, 20 and 21). 1. Housing. See Fig. 1, 2, 3 and 4

This invention is designed to attach to an electric hair clipper to perform absolutely safe, naturally looking and precisely barbering (hair length saved between 10mm and 150mm), even though the operator is not a trained barber.

It was impossible for a barber to cut his own middle length hair with an electric hair clipper over comb technique. Now do-it-yourself barbering with an electric hair clipper is possible with my invention.

With my invention an electric hair clipper can not only be one of the necessity implements of barber shops, but also one of the household utensil items.
