摘要：
A device with a pivoting work arm for carrying and positioning a tool which is moved by a modified Watts linkage powered by a linear actuator is provided with shock absorption adjacent both the fully extended and fully retracted work arm positions. The modified Watts linkage engages a pawl which rotates a lever arm in the same direction to actuate the same shock absorber(s) when the work arm is moved to both its fully extended and fully retracted positions.
