The utility model relates to an electronic trigger type safety gear which comprises a gear body provided with a guide rail channel, a brake roller and a fixed wedge which are installed on the gear body and located on the two sides of the guide rail channel respectively, and an electronic trigger piece installed on the gear body and used for replacing a traditional lifting mechanism. The brake roller is driven to move along the caliper body to approach the guide rail to realize braking; the two ends, in the guide rail channel direction, of the fixed wedge block abut against the clamp body and the displacement reset mechanism correspondingly, and the displacement reset mechanism is used for providing a displacement stroke for the fixed wedge block when the safety clamp is reset and resetting the fixed wedge block after displacement. According to the safety tongs, electronic triggering is achieved, and the reset force is small. 本实用新型涉及一种电子触发式安全钳，包括钳体，钳体具有导轨通道，还包括安装于钳体的制动滚柱和固定楔块，制动滚柱与固定楔块分别位于导轨通道的两侧，还包括安装于钳体的电子触发
