Wrench driven rotation hand tool with side handle

A hand tool, comprising:

• an elongated column (101) that includes a main shaft;
• an output interface (102) connected to an end of the main shaft for driving a cutter or a tool carried thereon;
• a handle (106) coupled to the column (101) for driving the hand tool manually;
• a transmission gearbox (107) mounted on the column (101), the gearbox having an input end that is coupled to said handle (106) and having an output end that is coupled to the main shaft;
• a one-way drive arrangement (109) connected between the handle (106) and the transmission gearbox (107), so that torque is transmitted to the main shaft in a single direction via the transmission gearbox (107) to rotate the main shaft in a single direction when the handle (106) is manually reciprocated, torque being transmitted to the main shaft when the handle (106) is moved in a first direction but not when the handle (106) is moved in a second direction,
• wherein the transmission gearbox (107) has a transmission speed ratio, so that a transmitting operation of different speed ratio is formed between the main shaft and the handle (106) when said handle (106) is driven rotatably in the first direction;
• and
• an additional handle (104) connected to the column (101) and extending radially for holding the hand tool steady.
