Description

Hand tool handle structure improvement

The invention relates to a handle structure, in particular to a structure improvement of a hand tool handle, which is coated with a cork fiber surface by a grip portion, and the cork fiber surface is pressed and molded by a mold to form a plurality of softwood plastic composite particles. Or a brush with a pointed hook to form a plurality of warped surfaces of different thicknesses and regular or irregular shapes by the secondary processing brush to achieve the purpose of increasing friction, elasticity and slowing the impact.

According to the modern industry, the rapid development of modern industry is not only a professional technician. The general public has very popular use of hand tools. In order to make the work of locking and unloading more convenient, high-quality hand tools are indispensable; there are many kinds of general hand tools. The conventional hand tool handle structure is generally cylindrical in shape, which is convenient for the user to grasp the ergonomic curvature formed by the hand, so that the operator can use the hand tool more comfortably and conveniently.

However, while the hand tool is being operated, the contact area with the handle of the hand tool affects the friction; if there is sweat or oil stain on the hand, the friction coefficient is reduced and it is easy to slip, so that the friction of the workpiece such as a screw or a screw is greater than The operator's rotational torque cannot be operated effectively.

In order to increase the contact area and friction between the handle of the hand tool and the palm, some conventional inventions may open a groove in the handle of the hand tool or arrange small protrusion particles on the handle of the hand tool. The friction is increased, but there is no anti-slip effect in the oily working environment; therefore, the present invention further improves the disadvantages of the conventional hand tool handle.

In view of this, the present inventors have intensively discussed the problems faced by the friction of the existing hand tool handles, and actively pursued solutions through years of experience in the development of related industries, and have been continuously researching and long-term testing. Finally, a hand tool handle structure was successfully invented, thereby overcoming the above-mentioned conventional problem that the anti-slip effect of the oil-filled environment cannot be solved.

The main purpose of the present invention is to develop a surface structure that is cope with the advancement of technology and the needs of the market to solve the problems often encountered by technical operators who often work in harsh environments with oil pollution.

A first embodiment of the improved handle structure of the hand tool comprises: a handle of a hand tool, which is integrally formed by plastic injection, and a through hole is formed at one end of the handle; the handle surface of the hand tool is a grip portion, and the handle ring is Forming a softwood fiber surface, wherein the softwood fiber surface is provided with a plurality of embossed granules by an upper mold and a lower mold inner surface, and the cork plastic fiber is floated on the surface of the grip portion by injection molding; The cork fiber surface is irregularly distributed with a plurality of cork plastic composite particles, and each of the cork plastic composite particles has irregular irregularities.

A second embodiment of the improved structure of the hand tool handle comprises: a handle of a hand tool, which is integrally formed by plastic injection, and a perforation is formed at one end of the handle; the handle surface of the hand tool is a grip portion, and the grip ring is The cork fiber surface is covered with a soft wood chip mixed plastic material, and the softwood fiber surface is formed by a double hook-shaped steel brush to form a plurality of irregularly distributed The warped surface, each of the warped surfaces has a different depth and irregular shape, so that the surface of the softwood fiber forms a surface such as a sawdust skin.

With this innovative and unique design, the present invention has the following advantages:

1. Make a pattern or any granules in the mold, let the elastic plastic sink, and the softwood particles floating on the surface can produce anti-slip effect.

2. On the smooth surface, the cork fiber surface is machined with a pointed hook and brush machine, and the surface layer fiber is changed into a rugged rough surface to increase the friction and achieve the anti-slip effect, which is much better than the conventional creation. Breakthrough and innovation.

3. The material of the softwood fiber surface has elasticity and slows down the impact effect.
