Problems solved by technology

However, the electric screwdriver is large in size and quality, and the price is high. It needs to be connected to the circuit, and it is not flexible enough to use.
Although the manual screwdriver is more flexible to use, the handshake part for twisting needs to be coaxial with the axial direction of the screwdriver during use, so in some small spaces, it is more difficult to screw the screw.
Moreover, using a traditional manual screwdriver can only turn the screw more than half a turn without turning it once, which is less efficient

Embodiment Construction

[0016] Below in conjunction with embodiment, the present invention is further described:

[0017] like figure 1 and figure 2 As shown in the middle embodiment, the screwdriver for this grip includes a handle 1 and an insertion rod 2; the insertion rod 2 is coaxially assembled with the handle 1, and the end of the insertion rod 2 can be used according to whether it is a flat-blade screw or a flat-blade screw. Phillips screw tightening to specific design and manufacture. The insertion rod 2 can be axially rotated relative to the handle 1 , and a transmission structure 3 is assembled inside the handle 1 , and the transmission structure 3 is connected with the insertion rod 2 in a transmission manner. The grip 1 is also equipped with a grip lever 4, and the grip lever 4 is connected to the transmission structure 3 through an anti-reversal structure 5, and the anti-reversal structure 5 can The torsion force is output horizontally, and the transmission structure 3 can output the...

Abstract

The invention provides a grip type screwdriver. The grip type screwdriver comprises a grip handle and an insertion rod, wherein a transmission structure is assembled in the grip handle, a grip strength rod is further assembled on the grip handle, and connected with the transmission structure through an inversion-preventing structure, the inversion-preventing structure can horizontally output torsion generated when a user grips the grip strength rod, the transmission structure can vertically output horizontal torsion, and the portion, gripped by the fingers, of the grip strength rod is connected with the grip handle through a spring. When the grip type screwdriver is in use, the user can grip the grip type screwdriver to carry out direct operation, and does not need to twist the wrist, and operation is freer; meanwhile, transmission is carried out on the insertion rod by gripping the grip strength rod, and thus the efficiency of turning screws is higher.

Description

[0001] technical field [0002] The invention relates to the technical field of hardware tools, in particular to a gripping screwdriver. [0003] Background technique [0004] A screwdriver is a tool used to turn a screw to force it into place; it is often used in production and life. Traditional screwdrivers are manually operated, with an axially elongated insertion rod mounted on a cylindrical handle. The end of the insertion rod is divided into a cross-blade screwdriver and a flat-blade screwdriver according to the screw opening method that needs to be turned. In order to install and remove screwdrivers more quickly, people have invented electric screwdrivers that use electric motors instead of manually installing and removing screws. However, the size and quality of the electric screwdriver are large, and the price is high. It needs to be connected to the circuit, and it is not flexible enough to use. Although the manual screwdriver is more flexible to use, it needs ...
