Self-generating ratchet screwdriver

Abstract

The invention relates to a self-generating ratchet screwdriver, which comprises a screwdriver head, an electricity utilization body, a generating component, a ratchet component and a handle, wherein the screwdriver head is arranged on the ratchet component; the ratchet component and the handle are connected in a rotatable mode and form an accommodating space; the electricity utilization body is connected with the generating component; the generating component is arranged in the accommodating space and comprises a magnetic body capable of generating a magnetic field, a closing coil capable of cutting the magnetic field generated by the magnetic body, and an energy storage device; the closing coil is arranged on one part of the ratchet component or the handle; the magnetic body is arranged on the other part of the ratchet component or the handle; and the handle and the ratchet component relatively move to drive the closing coil to cut a magnetic force line generated by the magnetic body so as to generate electric energy. The ratchet screwdriver is combined with a rotary structure of the ratchet screwdriver, a self-generating structure is increased, and the electric energy is generated to supply power to the electricity utilization body.

Description

technical field [0001] The invention relates to a screwdriver, in particular to a self-generating ratchet screwdriver. Background technique [0002] Screwdrivers can be divided into flat-shaped and cross-shaped screwdrivers according to the shape of the blade head, and their function is to tighten or loosen screws. During the working process of the screwdriver to tighten or loosen the screw, it is necessary to let go of the handle and change the handle for a second turn every time the screw is turned, which leads to low work efficiency and laborious work. In order to solve the situation of low working efficiency and laborious work, a ratchet wheel is added to the existing screwdriver. This structure can be continuously twisted without changing the handle. [0003] Combining the advantages of the existing ratchet screwdrivers, it has become an inevitable trend to use the internal remaining space of the ratchet screwdrivers to achieve certain functions. Contents of the inve...
