发明名称 Device for holding logs for sawing
摘要 A device for holding a log for sawing comprises a post having fixed thereto a pair of downwardly pointed spikes carried by a plate. A sleeve is slidable on the post and carries four upwardly pointed spikes on a plate and displaced a greater distance from the post 1 than are the spikes fixed to the post. The log is thus held in cantilevered fashion and the weight of the log causes the sleeve to jam in position against the post. The sleeve is provided with a spring to stop is sliding down the post when not in use. The post may be held in a sleeve hammered into the ground or it may be provided with a base so the device is free-standing.
