Abstract: An optical element driving mechanism is provided and includes a fixed assembly, a movable assembly, a driving assembly and a stopping assembly. The fixed assembly has a main axis. The movable assembly is configured to connect an optical element, and the movable assembly is movable relative to the fixed assembly. The driving assembly is configured to drive the movable assembly to move relative to the fixed assembly. The stopping assembly is configured to limit the movement of the movable assembly relative to the fixed assembly within a range of motion.

Abstract: A water hose winding apparatus mainly includes an upright plate and a fastening frame, wherein the top portion of the upright plate forms a handle ring and the lower end thereof is disposed with a peg rod; two lateral end portions of the fastening frame form bend portions with forked openings at the distal ends; one end portion of a shaft sleeve pivotally couples at the center of a support plate; the center of a rotary disc is disposed with a shaft hole; the shaft sleeve rotates synchronously with the rotary disc and a shaft; one end of the water hose inserts into the through hole of the rotary disc thereby coiling the hose body around the shaft sleeve; the other end thereof is stored at or pulled outwardly from the forked opening area.

Abstract: A wrench tool includes a member having an engaging opening formed in one end for engaging with fasteners to be driven. The other end of the member includes an orifice parallel to the longitudinal axis and the other orifice perpendicular to the previous orifice, for allowing the orifices to engage with different tool members. The member includes a pair of tapered surface having a number pairs of opposite engaging surfaces for engaging with fasteners of different sizes. A coupler is pivotally coupled to the member and the orifices are formed in the coupler.

Abstract: A driving tool includes a barrel having a front hole and having a rear handle inclined relative to the barrel for forming a gun-shaped tool and for allowing the user to easily hold the driving tool and to easily apply a force against the driving tool. A driving stem is rotatably engaged in the hole of the barrel for engaging with a tool bit. A hand grip is coupled to the driving stem via bevel gears for rotating the driving stem. A cartridge is rotatably engaged in the barrel and has a ratchet mechanism for controlling the actuating directions of the driving stem.
