Abstract: A multi-purpose portable power bank and/or a mobile phone fixing device includes a bearing seat and an elastic tightening element. One side of the bearing seat is provided with a fitting and pressure bar for accommodating a mobile phone, and the opposite side thereof is provided with a tightening and pressure bar for accommodating a power bank. One end of a base of the elastic tightening element is provided with a recess to be bonded to a rod, and one end of the recess is provided with an outwardly extending strap. The opposite end of the base is provided with a steel buckle plate; whereby the bearing seat enables the mobile phone and the power bank to be assembled together, such that the mobile phone can be charged at any time. The bearing seat can be quickly mounted to the rod through the elastic tightening element, such that a rider can view the mobile phone screen directly.

Abstract: A measuring tape device has a hook piece consisting of a hook plate and a pulling plate to be connected into a L-shaped structure; the edges of the hook plate are formed with an U-shaped extruded holder for holding an anti-slip piece, said pulling plate has a hollow area, a magnetic base to be screwed onto the tape is put on said pulling plate with a convex bottom portion held by said hollow area and then the magnetic base is attached to the upper surface of said pulling plate, such that said pulling plate can be moved forward and backward along the bottom surface portions surround said convex portion of said magnetic base. Besides, there is a box formed on said magnetic base for safely holding a magnetic element.

Abstract: A measuring tape device has a hook piece. The hook piece is used for preventing the tape from slipping off from an object of measure. The hook piece consists of a hook body and an anti-slip piece; the hook body consists of a pulling part and a connecting part; the pulling part is a flat surface, the connecting part extends out from one side of the pulling part in the direction that is perpendicular to the pulling part; the anti-slip piece is adhered onto the inside surface of the pulling part; and magnetic pieces are attached to the outside surface of the pulling part. Therefore, during the measuring process, both the anti-slip piece and the magnetic pieces may help keeping the hook plate of the measuring tape attaching to the object of measure and hence the tape does not slip off from the object of measure easily.

Abstract: A measuring tape device with improved carriage apparatuses of present invention comprises of a casing; a coiled measuring tape that is located inside the casing; one end of the measuring tape must be extended outside of the casing for taking measurement; a control mechanism that locks or releases the measuring tape is set on one end of the casing; and a side-clip component; the invention is characterized in that: the device has a protective element that is set at the front end of the casing, such protective element can prevent injury to user's finger during the retracting motion of the measuring tape, and the device may also be hanged onto a wall when it is not in use; the side-clip component is located at the top circumference surface of the casing, such that the side-clip can be assembled on either side of the casing to accommodate for both left-handed or right-handed users.

Abstract: A measuring tape device with automatic locking mechanism comprises of a casing, a bobbin that is set within the casing with a spring, a coilable tape that is contained in the casing. One end of the tape is connected to the spring and is wound around the bobbin, while the other end is extended outside through an aperture that is formed at the lower end to of casing, and this other end is connected to a hook member. The device also comprises of a stopper, it consists of an end that is positioned on the linear portion of tape, and an actuator that is connected to the end portion by a linkage part. The actuator is extruded outside and is settled at the surface of the casing. The device includes a hinge joint for fixating the stopper inside the casing and for allowing the stopper to rotate, and an elastic member placed between the casing and the linkage portion.

Abstract: An improvement on the structure of a measuring tape device is that a magnetic mechanism is secured at the distal end of a measuring tape. The magnetic mechanism is not placed onto the leg piece of the hook member and thus is not formed as part of the body of the hook member of the measuring tape. The front end of the magnetic mechanism is placed in alignment with the “0” cm mark on the measuring tape. During measuring process of an object of measurement and a designated point, the magnetic mechanism allows the measuring tape to be magnetically attached to the surface of the object and anchored at the exact starting point of measurement, and therefore, the measuring precision will not be skewed because of thickness of the hook member or because of the gap caused by the movable mechanics of the hook member.

Abstract: A construction for position fixing of a rule tape comprises a main housing having a handle formed at its upper end, and a wound rule tape for measurement in the main housing. The free end of said rule tape has a buckle ring with a magnetic adjacent to said buckle, to absorb the generation of a pulling force due to the weight of buckle ring A fixing element is installed in the main housing.

Abstract: The present invention relates to an improvement of tape rule, in particular to end portion of the measuring tape which includes measuring tape connecting portion and hook hanging portion, both parts are made in same material as whole body. The surface of measuring tape connecting portion is formed with rivets. The hook hanging portion of measuring tape has at least 1 mm thickness, its surface contains holes with enough depth to enclose a magnetic object, the magnet's thickness does not exceed the depth of the holes; the surface of hook hanging portion is wrapped with a holding element covering its front surface, rear surface, and the magnetic object enclosed.

Abstract: Disclosed is a vehicle wheel measuring apparatus, comprising a push rod, a counter, a wheel, and a gear coupled mechanism, wherein the counter is disposed on top of the push rod. Through the gear coupled mechanism, the axle center of said counter and the wheel axle form a joint relationship having the same rotational cycles. A front yoke is attached to the wheel axle in the end of said push rod, and a set of magnetic element is disposed between the wheel axle and the interior side of the front yoke. This prevents the wheel from rotating by itself that affects actual measured distance.
