Abstract: An electronic torque wrench includes a wrench head unit adapted to engage and turn a fastener, a tubular wrench body which includes a front tubular end fittingly engaged and secured with the wrench head unit, and an intermediate tubular segment having an access opening, a grip handle which is configured to securely grip a rear tubular end of the tubular wrench body, a mounting shell which is sleeved on the intermediate tubular segment, and which has an access hole communicated with the access opening, a housing sleeve sleeved on, and rotatable relative to the mounting shell about a lengthwise axis, and a display unit disposed on the housing sleeve to provide a display representing a torque measured by a strain gauge on the wrench head unit. By rotating the housing sleeve, the display unit can be adjusted to a desired angular position for being viewed easily by the user.

Abstract: An adjustable driving tool includes a handle and a driving rod. The handle has a limiting portion disposed in the handle and a slot. The limiting portion has an inner space communicating with openings of a first sleeve portion and a second sleeve portion. The slot communicates with the inner space. The handle provided with a pin disposed through the inner space, and the first and second sleeve portions are disposed around the pin. The driving rod has a working end and a fixation end having an elongate through hole around the pin. The fixation end is disposed into the inner space through the slot. The driving rod is slidable relative to the pin, and the fixation end is controllably selectively inserted into the first sleeve portion or the second sleeve portion so that the driving rod is held.
