Abstract: A display equipment connected to an electronic device is provided, including a flat optical component and a pivot unit, wherein the optical component includes a semitransparent reflective element. The pivot unit is pivotally connected to the optical component and the electronic device. When the optical component is in a first position and substantially parallel to a display surface of the electronic device, the light emitted from the display surface passes through the optical component. When the optical component rotates from the first position to the second position relative to the electronic device with an inclined angle formed between the optical component and the display surface, the light emitted from the display surface is reflected by the semitransparent reflective element to a user.

Abstract: An angle adjusting device of a steel bar bending apparatus includes at least an adjusting unit, having a casing inside which a worm and worm gear pair is disposed. The worm is rotatably fit over a shaft which is in turn rotatably supported within the casing. The shaft is driven by a driving motor of the steel bar bending apparatus. The worm is fixed on a spindle having an end extending outside the casing to which a rotation knob is releasably fixed for rotating the worm about a central axis of the shaft. A switch is attached to the worm so that the angular position thereof about the central axis is adjustable by rotating the knob. A triggering member is fixed on the shaft so that when the shaft is driven by the motor to reach and thus trigger the switch, the motor is turned off by the operation of the switch. The casing is provided with a top projection and a corresponding bottom recess for receiving and fixing the top projection of a second unit for stacking the units over each other.
