Abstract
A motorized hammer has a body and a tool holder which is mounted on the front of the body and is capable of imparting impacts via the tool in the holder. A rear handle is, moveably mounted to the rear of the body via at least one movement control mechanism which is capable of moving towards or away from the body. A biasing mechanism biases the rear handle away from the body and each movement control mechanism includes a first mount. A rod having a longitudinal axis is rigidly connected at one of it ends to the first mount. A second mount slidingly engages with the rod at two distinct points only along its length to allow the rod to slide relative to the second mount in a direction parallel to the longitudinal axis. The second mount prevents the rod from moving in a direction perpendicular to the longitudinal axis.
