Description

Screwdriver convenient to use

Technical Field

The utility model relates to a screwdriver, especially a closing device of screwdriver handle.

Background

The screwdriver is used for screwing in and unscrewing the screw.

The screwdriver is provided with a strip-shaped handle, one end of the handle is connected with a straight rod-shaped tool bit, and the outer end of the tool bit is provided with a cutting edge. When the screwdriver is used, the handle is held by hand, the cutting edge of the screwdriver bit is pressed in the gap on the screwdriver head, the gap on the screwdriver head is in a straight shape and a cross shape, and the handle is rotated to screw in or screw out the screwdriver. When the screw is screwed in or out, two forces are applied to the handle, one is a pressing force pressing the screw, and the other is a rotating force rotating the handle.

When the screwdriver is used, the screwdriver handle is held by hands, the blade is embedded into a gap of the screw, the screwdriver handle is held by hands, and the handle is rotated by rotating arms while pressure is applied to the screw.

When the handle is rotated by the screwdriver, the arm is rotated by holding the handle of the screwdriver by hand, the arm can only rotate for a limited angle due to the limited rotation angle of the arm, the screwdriver needs to be lifted after the arm rotates for the limited angle, the blade is separated from the gap of the screw, the screw loses pressure, the blade needs to be embedded into the gap of the screw again after the arm rotates, then pressure is applied to the screw, and then the arm is rotated. The screwdriver can not realize screwing in and screwing out of the screw under the condition of continuously applying pressure to the screw, is inconvenient to use, and particularly wastes time and labor when screwing in and screwing out longer screws.

Disclosure of Invention

The utility model aims at overcoming the above-mentioned not enough, provide a convenient to use's screwdriver.

The utility model is realized by the following method.

The screwdriver that facilitates use has the bar handle, and the one end of handle even has the straight rod-shaped tool bit that the length direction of axis and handle is the same, and the tool bit outer end has the cutting edge, and the other end of handle has the closing device of handle, and the closing device of handle has the bearing frame in handle one end, and the bearing frame is embedded to have the axis and the axis of tool bit ball bearing on same straight line, has the pressure cap in ball bearing's the shaft hole.

The utility model discloses the other end of handle has the bearing frame, and the bearing frame is embedded to have the axis of axis and tool bit ball bearing on same straight line, has the pressure cap in ball bearing's the shaft hole. When the screwdriver is used, the handle of the screwdriver is held by a hand, the blade is embedded into a gap of a screw, then the pressing cap on the handle is pressed by a palm, pressure is applied to the screw, the handle is rotated by fingers, or the pressing cap on the handle can be pressed by one hand, the handle is rotated by the other hand, and the screw can be screwed in or out conveniently under the condition that the pressure is continuously applied to the screw. Especially when screwing the long screw, labour saving and time saving.

The present invention will be further described with reference to the accompanying drawings.
