  • Motor-driven fastening tool
    Patent number: 9701001
    Abstract: A fastening tool is provided with a housing having a fastener outlet. A striker is mounted for translation in the housing to drive a fastener from the fastener outlet in an unloaded position. A biasing member cooperates with the striker to urge the striker towards the unloaded position. A motor is oriented in the housing. A cam is driven by the motor, and has a cam surface in cooperation with the striker such that rotation of the cam translates the striker to a loaded position and to a release position whereby the biasing member drives the striker to the unloaded position. The cam surface is profiled to require a constant torque from the rotary input during translation of the striker to the loaded position while loading the biasing member.
