Abstract: A fixing assembly for carrying a bike includes a main body having a transverse hole provided therein with transverse ribs to be secured with a rod of a carrying stand on a motor vehicle. The main body is formed with a concave portion with vertical ribs for positioning a bike frame rod or a bike wheel thereon, having a first strap with lots of one-way ratchets and a second strap for receiving an engaging device that has a base to be secured with the second strap. The base is provided with a micro-adjusting member for adjusting combined tightness of the first and the second strap, and an engaging member for engaging the one-way ratchets of the first strap to prevent the first strap from moving reversely and a releasing member for pulling open the engaging member to release and separate the first strap and the second strap.

Abstract: The bicycle carrier rack includes a main frame, a swaying frame and an adjustment device. The main frame stands vertically, combined with the swaying frame by the adjustment device. Fixed at the bottom portion of the main frame is a positioning rack to connect with a vehicle or a trailer. Two positioning holes are bored in the main frame. The swaying frame is combined with the main frame by the adjustment device, having a positioning member and a positioning projection employed to primarily position with positioning holes of the main frame. The adjustment device has a shell, and a movable element installed in the shell to co-work with the positioning member of the swaying frame. With a starting element to control the movable element, the adjustment device can work to alter the combined status of the main frame and the swaying frame, enabling the bicycle carrier rack unfolded or folded.

Abstract: A multi-functional air circulation system includes a bottom base, a flow-splitting base, a filter and a main engine. The bottom base has a lower flow-guiding surface, a net, and a space used to contain diverse improving agents. The flow-splitting base is fixed on the bottom base, including an inner flow-guiding surface to rush air flow generated by a blade member down to the bottom base. The filter is laid at an exit of the inner flow-guiding surface, composed of two filter bases forming a room between them for containing aromatic powder, etc. The main engine includes a motor having its shaft fixed with a blade member, and a control system. The motor is installed in a rear shell combined with a front shell. Air is sucked in through the rear shell to run through an ornamental shell and the flow-splitting base to enter a room. The main engine and the bottom base can also be assembled to work independently.

Abstract: A bike frame for a sedan includes a horizontal main frame to be combined with a movable frame by adjusting devices that function to adjust the combined conditions between the main frame and the movable frame. The movable frame is provided with an auxiliary frame serving as a sitting means of combination of the movable frame and the rear side of a sedan. The adjusting devices are respectively disposed with a movable member to be fitted on the main frame, and formed with a receiving notch for receiving the movable frame and provided with a driving member combined with and positioned under the movable member. Further, the adjusting devices respectively have an elastic member for positioning the movable member, and a fit cover for covering all foresaid members and combined together with the main frame and the movable frame.

Abstract: A lockable torque-limiting driver includes a body and a sleeve received in a sleeve chamber of the body and secured therein by recesses inside the body. The sleeve is provided with projecting edges on the outer wall to be respectively fitted in the recesses of the body, plural recessed grooves at the inner wall for fixing an upper cam, and female threads at the inner wall to be screwed with the male threads of a torque-limiting member, further disposed with plural positioning serrations at topside and a center chamber inside. The upper cam and a lower cam respectively have one-way serrations to be mutually engaged. The torque-limiting member is fixed with positioning projections to be actuated to move on the positioning serrations of the sleeve and give out sounds by which a user can know a torque limiting extent desired.
