HAND TOOL HAVING A HEAD WHICH IS POSITION-ADJUSTABLE AND LOCKABLE RELATIVE TO A HANDLE

摘要

A hand tool includes a head and a handle. The head is pivotally mounted to the handle, permitting the position of the head to be changed relative to the handle. In addition, the tool includes a primary locking mechanism and a secondary locking mechanism. The primarily locking mechanism primarily fixes the head relative to the handle in a particular position. The secondary locking mechanism can be used to further lock the head and handle. The locking mechanisms are actuated by movement of a sleeve which is located on the handle.
