Abstract: An electronic torque wrench a wrench head unit adapted to engage and turn a fastener, a tubular first wrench body securely engaged with the wrench head unit, a tubular second wrench body coupled and aligned with the first wrench body by a fitting member to permit rotation of the second wrench body relative to the first wrench body, a mounting shell sleeved on the second wrench body for mounting a display unit to provide a display representing a measured torque. By rotation of the second wrench body, the display unit can be adjusted to a desired angular position for being viewed easily by the user.

Abstract: A cutter assembly for an electric pencil sharpener has a cutter bracket and a cutter. The cutter bracket has a pencil sharpening hole and an engaging structure. The pencil sharpening hole is defined in the cutter bracket for a pencil to be inserted into the pencil sharpening hole. The engaging structure is formed on the cutter bracket to engage a rotating frame in the electric pencil sharpener. The cutter is mounted rotatably on the cutter bracket. Accordingly, the cutter assembly is replaceable for the electric pencil sharpener when the cutter of the cutter assembly is damaged or worn.

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: A portable over-the-ear miniature sound box device comprises a loudspeaker, a first chamber and a second chamber. The loudspeaker is located in the first chamber. A first sound output hole of the first chamber is connected with a sound-receiving hole of the second chamber. A second sound output hole is disposed at the opposite side of the sound-receiving hole of the second chamber. A sound signal first resonates in the loudspeaker and is then sent through the first chamber to second chamber. Sound resonates again in the second chamber and is finally sent out via the second sound output hole. Because the sound signal resonates twice and is more convergent and the first resonance occurs in the loudspeaker, the bass will be thicker and more easily heard by human ears, hence solving the problem of easy divergence of the bass.
