Embodiment Construction

[0054] The present invention will be further described below in conjunction with the accompanying drawings of the description.

[0055] Such as Figure 1-10 , Figure 11-19 , Figure 20 Shown are the views of three embodiments of the reversible screwdriver with manual and electric working modes of the present invention, these embodiments all include a handle 01, a working rod 02 carried by the handle to realize manual torque output, The working rod 02 is assembled on the handle by the reversing mechanism 03 located at the front end of the handle and extends forward. The reversing mechanism 03 includes a reversing sleeve 31 and a reversing dial 32 driven by the reversing sleeve (see Figure 8 , Figure 13-15 ), turn the reversing sleeve relative to the handle and switch the reversing mechanism with the reversing dial to switch the manual torque output direction of the working rod; in other words, when the reversing sleeve is turned to a position relative to the handle, the r...

Abstract

The invention discloses a reversible rotary jig with manual and electric operation modes and belongs to manual and electric tools. A ratchet wheel screwdriver of an existing manually-operated three-gear manual rotary jig is insufficient. A power source, a circuit board controlling the power source to rotate, and a power source for supplying power to the power source and the circuit board are arranged in a hand shank. The power source and an operation lever are in transmission connection so as to achieve electric torque output. The circuit board is connected with a control switch and a reversing switch. The hand shank is provided with a button corresponding to the control switch. A steering dial piece extends to the reversing switch and rotates relative to the hand shank, and a rotary reversing sleeve drives the reversing dial piece to switch the reversing switch so that the electric torque output direction of the operation lever can be switched. The manual torque output direction is the same with the electric torque output direction. A user can select the manual operation mode to output high torque or the electric operation mode for quick screwing according to demands.

Description

technical field [0001] The invention belongs to manual and electric tools, in particular to a reversible screwdriver with manual and electric working modes, which is used for screwing operations. Background technique [0002] A manual screwdriver is a manual tool that uses a handle to rotate and drive the working rod to apply torque to the corresponding parts. A screwdriver (also called a screwdriver) is a representative example. The traditional manual screwdriver is to fix the working bar and the handle together. When using it, such as tightening or loosening a screw with a screwdriver, since the hand holding the handle can only rotate a small angle, when it is necessary to When a part is rotated multiple times in a row, it is necessary to stop and let the hand turn an angle in the opposite direction. One way to use it is to temporarily withdraw the hand-held screwdriver from the part to achieve reverse rotation. In this way, the screwdriver needs to be aligned with the par...
