FIELD: process engineering.
SUBSTANCE: invention relates to tools intended, for example, for hammering in the nails. Proposed driven tool comprises moving element, drive of the latter including drive initiation circuit, control circuit and switch to generate operation signal. Control circuit outputs control signal in response to operation signal output by operation switch. Initiation circuit comprises drive assembly when control signal is sent from control circuit. Drive initiation is locked when control signal from control signal is abnormal.
EFFECT: locking of moving element in abnormal operating conditions.
