Hand tool handle structure improvement

The present invention relates to a handle structure, in particular to a hand tool handle structure improvement, in which a soft wood fiber surface is attached by a grip portion, and the softwood fiber surface is press-molded by injection molding to form a plurality of plastic particles, or A tip-shaped brush is formed by a secondary processing brush to form a plurality of warped surfaces of different thicknesses and regular or irregular shapes for 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 creations may open a groove in the handle of the hand tool or arrange small protrusion particles on the handle of the hand tool. Increase friction, but there is no anti-slip effect in a greasy working environment; therefore, this creation It is further improved on the shortcomings of the conventional hand tool handle.

In view of this, the creator is in-depth discussion on the problems faced by the friction of the existing hand tool handles, and actively seeks solutions through years of experience in the development of related industries, through continuous efforts and long-term testing, Finally, a hand tool handle structure was successfully created to overcome the aforementioned conventional anti-slip effect in an oil-stained environment.

The main purpose of this creation is to cope with the advancement of technology and the needs of the market, to solve the problems often encountered by technical operators who work in the harsh environment of oily environment, and to develop a surface structure.

A first embodiment of the hand tool handle structure improvement comprises: a hand tool handle integrally formed with a through hole at one end; the hand surface of the hand tool is a grip portion, and the grip portion is annularly covered. A cork fiber surface with high friction coefficient and elasticity is arranged, and the irregular surface of the cork fiber surface is provided with a plurality of plastic particles, and the plastic particles are different in depth and irregular.

A second embodiment of the hand tool handle structure improvement comprises: a hand tool handle integrally formed with a through hole at one end; the hand surface of the hand tool is a grip portion, and the grip portion is annularly covered. A cork fiber surface with high friction coefficient and elasticity is arranged, and the irregular surface of the cork fiber surface is provided with a plurality of warped surfaces, and the warped surfaces are different in depth and irregular.

With this innovative and unique design, this creation 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. Machining the softwood fiber on a smooth surface with a pointed hook and brush machine In the face, the surface layer of the fiber is changed into a rugged rough surface to increase the friction and achieve the anti-slip effect, which is more breakthrough and innovative than the conventional creation.

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

The embodiments, structures, and features of the present invention are described in detail with reference to the preferred embodiments of the present invention.

Referring to FIG. 1 to FIG. 3, in a first embodiment of the present invention, a hand tool handle structure is improved, comprising: a hand tool handle 10 integrally formed with a through hole 101 at one end; the hand tool handle The ten-week surface is a grip portion 11, and the grip portion 11 is annularly coated with a high-friction coefficient elastic cork fiber surface 12, and the softwood fiber surface 12 is irregularly irregularly provided with a plurality of plastic particles 13, each of the plastic particles 13 is different in depth and irregular.

Wherein, the upper surface of the upper mold 30 and the lower mold 31 are respectively provided with a plurality of pressed granular members 32 or engraved, and the cork plastic fibers are floated on the granular or patterned top by injection molding. The end portion of the grip portion 11 produces an anti-slip effect.

Referring to FIG. 4 to FIG. 5 , in a second embodiment of the present invention, a hand tool handle structure is improved, comprising: a hand tool handle 10 , which is integrally formed with a through hole 101 at one end; the hand tool handle The ten-week surface is a grip portion 11, and the grip portion 11 is annularly coated with a high-friction coefficient elastic cork fiber surface 12, and the softwood fiber surface 12 is irregularly concave and convex to provide a plurality of warped surfaces 14, each of which has a warp surface The curved surface 14 is different in depth and irregular.

Wherein, the cork fiber surface 12 is formed by a secondary processing brush to form each of the warping surfaces 14 by a hook-shaped steel brush 50, and the softwood fiber surface 12 is made of soft wood chips, so The cork fiber surface 12 forms a surface such as a wood chip, so that the grip portion 11 produces an anti-slip effect.

Referring to FIG. 1 to FIG. 5 , a screw driver 20 protruding from the hand tool handle 10 is disposed in the through hole 101 , and the end of the screwdriver 20 has a word, a cross shape or any rotation and pull. The function head of the moving screw.

The surface of the grip portion 11 is bored with a plurality of through holes 111, and each of the through holes 111 can be inserted into a hanging hook or a round bar to facilitate the user to receive and apply force.

The grip portion 11 is annularly recessed with at least one concave annular surface 112. The concave annular surface 112 covers the softwood fiber surface 12 and has a depth of 1 mm to 3 mm.
