Title:
MANUAL TOOL CAPABLE OF ACHIEVING BIDIRECTIONAL OUTPUT OF TORQUE
Document Type and Number:
WIPO Patent Application WO/2021/175253
Kind Code:
A1
Abstract:
A manual tool capable of achieving bidirectional output of torque, comprising a handle (100), a spindle (200), a transmission device (300), a ratchet device (400), and a ratchet reversing device (500). When a ratchet reversing ring (501) of the ratchet reversing device (500) is located in a clockwise position, no matter whether the handle (100) rotates clockwise or anticlockwise, the spindle (200) rotates clockwise to output torque from the handle (100); when the ratchet reversing ring (501) of the ratchet reversing device (500) is located in an anticlockwise position, no matter whether the handle (100) rotates clockwise or anticlockwise, the spindle (200) rotates anticlockwise to output torque from the handle (100); when the ratchet reversing ring (501) of the ratchet reversing device (500) is located at a fixed position, both the spindle (200) and the handle (100) rotate in the same direction to output torque from the handle (100), and the output torque is large. Torque output from existing screwdrivers capable of bidirectional output is low, and the manual tool capable of achieving bidirectional output of torque in the present invention can output torque by means of bidirectional rotation of the handle, and can also output large torque.
