Description

Anti-slip screwdriver

Technical Field

The utility model relates to a screwdriver technical field especially relates to an antiskid screwdriver.

Background

A screwdriver is a hand tool used to tighten or loosen a slotted bolt or screw. The screwdriver utilizes the working principle of the wheel axle when being used for screwing the screw. The larger the wheel, the more labor-saving, so that the screwdriver with a thick handle is more labor-saving than the screwdriver with a thin handle for screwing.

The existing screwdriver sequentially comprises a handle, a screwdriver rod and a screwdriver head, and the handle is usually made of hard materials. When the screwdriver is used, the screwdriver bit is embedded into the notch of the screw, the handle is held by hand and the force is applied by rotation, so that the screw is screwed or unscrewed.

In foretell operation process, the handle is handed to the palm and direct application of force, because the handle is hard material, leads to handle and palm to skid relatively easily, not only makes the handle break away from the palm easily, and when skidding, still can cause the friction injury to the palm.

SUMMERY OF THE UTILITY MODEL

The not good problem of screwdriver handle antiskid effect in to the in-service use, the utility model provides an antiskid screwdriver has good antiskid effect.

In order to achieve the above purpose, the utility model provides a following technical scheme:

Through the technical scheme, the hard inner handle is made of hard materials, and the hard inner handle is not easy to slip when being connected with the cutter bar, so that force application is convenient; the hard inner handle is provided with the elastic sleeve, so that the hard inner handle can be protected, meanwhile, the hardness of the elastic sleeve is low, a hand and the elastic sleeve are in comfortable contact, and the holding feeling of the handle can be improved; the elastic sleeve is provided with an anti-slip block at the position far away from the cutter bar, when the handle is held tightly, the palm is attached to the anti-slip block, the friction force between the palm and the handle is increased, the palm is not easy to slip when force is applied to the handle, and the screw driver is convenient to twist.

Furthermore, the one end that the cutter arbor was kept away from to the handle is protruding setting and forms the protruding position of being convenient for to hand, and the skid resistant course sets up on the elastic sleeve that protruding position corresponds.

Through the technical scheme, one end of the cutter handle, which is far away from the cutter bar, is convexly arranged, so that when the handle is held by a palm, the palm core of the palm is coated with a convex position, namely the shape of the handle is matched with the palm, so that the palm can apply force to the handle; the palm mainly acts on the convex position, and the anti-skid block is also arranged on the convex position, so that the anti-skid effect is improved.

Furthermore, a plurality of anti-skidding grooves are formed in the surface, away from the handle, of the anti-skidding block.

Through above-mentioned technical scheme, through setting up anti-skidding groove to when palm and non slipping spur relative movement, the top edge and the palm butt in anti-skidding groove, and the resistance that the increase palm received, in order to improve anti-skidding effect.

Furthermore, one end of the handle close to the cutter bar is arranged in a concave mode and is provided with a concave position facilitating force application of fingers.

Through above-mentioned technical scheme, because partial crowd is when handing this screwdriver, the palm of palm and protruding position contact, the finger can with concave position butt, when the application of force, mainly rely on the finger application of force, the surface butt of finger card and concave position promptly to play spacing effect to the finger, avoid the finger to move towards the cutter arbor along handle length direction, have good anti-skidding effect.

Furthermore, the concave position surface is arranged into a first base surface and a second base surface from the direction of the cutter rod towards the convex position, the intersection line of the first base surface and the second base surface is the lowest point of the concave position, and a plurality of anti-skidding units are fixed on the first base surface.

Through above-mentioned technical scheme, set up anti-skidding unit on the second base face, anti-skidding unit sets up on first base face, and this anti-skidding unit supplies user's finger to press promptly to improve anti-skidding effect.

Furthermore, a plurality of anti-slip strips are fixed on the surface of the anti-slip unit, which is far away from the first base surface, the anti-slip strips are distributed along the length direction of the handle, and each anti-slip strip is arranged along the circumferential direction of the handle.

Through above-mentioned technical scheme, through setting up the antislip strip to the resistance that the finger received is pointed in the increase, and the antislip strip sets up along handle circumference, thereby the antislip strip is perpendicular with the effect direction of pointing, and the antislip strip distributes along handle length direction, stops with the improvement to the multistage of finger.

Furthermore, the handle is provided with a stress application hole which is vertical to the handle and penetrates through the handle.

Through the technical scheme, the force application hole is formed in the end portion of the handle, and when the screwdriver screws the screw, the torsion bar can be inserted into the force application hole, so that the torque is increased, and the strength is saved. In addition, the force application hole can also be used for hanging a screwdriver.

Furthermore, the stress application hole is far away from the cutter bar.

Through the technical scheme, the stress application hole is far away from the cutter bar, so that when the stress application hole is inserted into the torsion bar, the moment is increased, and the screw can be screwed and unscrewed quickly.

Furthermore, a knocking cap is fixed at the end part of the handle far away from the cutter bar, and the knocking cap and the cutter bar are coaxially arranged.

Through above-mentioned technical scheme, when the notch of screw rusted, hit the cap through strikeing with the tool bit in the notch butt to make the quick card of tool bit go into the notch intraorally, thereby reduce the injury that the handle received.

Compared with the prior art, the beneficial effects of the utility model are as follows:

(1) the hard inner handle is provided with the elastic sleeve, the hardness of the elastic sleeve is low, the grip feeling of the handle can be improved, one end of the elastic sleeve, which is far away from the cutter bar, is provided with the anti-slip block, when the handle is gripped, the palm is attached to the anti-slip block, the friction force between the palm and the handle is increased, the palm is not easy to slip when force is applied to the handle, and the screw driver can be conveniently screwed;

(2) the hand-held electric tool is convenient to hold by arranging the convex position and the concave position;

(3) the anti-slip unit is arranged on the second base surface and arranged on the first base surface, namely the anti-slip unit is pressed by fingers of a user, so that the anti-slip effect is improved.
