Abstract: An image rendering device and an image rendering method are disclosed. For the elements of the image rendering device, a first sensor and a second sensor are configured to sense a target object in a two-dimensional (2D) mode and three-dimensional (3D) mode to generate a first surface-color-signal, a first 3D-depth-signal, a second surface-color-signal and a second 3D-depth-signal respectively. An IR projector is configured to generate an IR-dot-pattern. A processor is configured to control the IR projector to project the IR-dot-pattern on the target object in the 3D mode, and configured to process the first surface-color-signal, the second surface-color-signal, the first 3D-depth-signal and the second 3D-depth-signal to obtain a color 3D model of the target object.

Abstract: A tool assembly for screwdriver with quick-release drill bits includes a bit main body, a sliding sleeve, a spring and a locating bolt. The bit main body has a shaft, and an outer periphery of a front end of the shaft has a plurality of axial cutting surfaces to form a connecting portion with a polygonal cross section. The sliding sleeve comprises a rear end and a front end, and a driving hole with a polygonal cross section axially penetrates through the sliding sleeve. An engaging groove formed at an inner periphery of the driving hole is located adjacent to the rear end of the sliding sleeve. The spring, the locating bolt and the engaging groove are configured to effectively shorten lengths of the connecting portion of the main body and the sliding sleeve thus lowering the manufacturing cost and increasing the competitive advantage in the market.

Abstract: A sleeve may include a hexagonal engaging hole at one end that engages with the screw nut and a coupling hole at the other end that engages with a wrench; wherein the engaging hole is inwardly tapered and the taper angle is two to four degrees, thereby enabling easy engagement of the engaging hole with screw nut; and there is a dodge groove formed at each corner of the hexagonal engaging hole and each pair of adjacent dodge grooves are separated with a driving block; and the surface of each driving block that touches the screw nut is concave and thus a driving corner is formed on each side of the driving block; and each driving block has a groove and thus two adjacent interior corners are formed at the bottom of the groove.
