Abstract
Torque restricting structure of pin hammer-type hammering: mechanism, including: an anvil having a shaft body, two symmetrical arched jaws projecting from the middle of the shaft body opposite to each other; two hammering pins each having a column body parallel to the shaft body of the anvil, the hammering pins being axially movable between a hammering position and a separating position, whereby when in the hammering position, a lateral face of each hammering pin hammers a lateral face of a corresponding projecting jaw and when in the separating position, the hammering pins are separated from the projecting jaws; a locating guide section; and a cam having a ridge section for abutting against the locating guide section. When the cam and the locating guide section are moved relative to each other, the cam is pushed to drive the hammering pins to move between the hammering position and the separating position.
