Abstract: A pair of hairdressing scissors comprises a first blade, a second blade pivotally secured to the first blade, at least two recesses formed at least one of the first and second blades, and at least a retainer fixed on at least one of the first and second blades. The retainer has two retaining portions each having an edge, two pairs of scissors are secured to each other in such a manner that an edge of a retainer of a first one of the two pairs of scissors is locked in two recesses of a second one of the two pairs of scissors.

Abstract: The present invention provides a dial for a combination lock, which mainly includes a toothed wheel additionally configured on a side of conventional type dial provided with an internally mounted notched wheel. A plurality of external teeth are circum-located on an outer edge of the toothed wheel, and a center of another notched wheel is provided with a rotating shaft, lateral to which is provided with a notch. A plurality of teeth spacings circum-located on an outer edge of the notched wheel mutually engage with external teeth of the notched wheel of the dial. Accordingly, the dial is able to simultaneously actuate and rotate two notched wheels, thereby improving innovative effectiveness of the combination lock.

Abstract: A portable toilet and bathing chair comprises a seat of rectangular shape, having a central opening, handles on left and right edges, two positioning openings on an upper side close to a rear edge, two storing depressions in a lower side parallel to and close to the left and right edges, at least three projections on the lower side, and four fastening assemblies on the lower side close to four corners, a backrest of rectangular shape, movable to a folded state close to the lower side of the seat, having positioning holes which are in the folded state entered by the projections of the seat and a lower edge with two holding extensions that are inserted into the positioning openings of the seat, and four feet, in a mounted state mounted on the seat at the lower side thereof close to the four corners thereof and being removable therefrom, wherein for folding, the four feet are removed from the seat and stored in the storing depressions, and the backrest is brought into the folded state thereof.

Abstract: A movable cover-plate of a computer host is installed on a front panel of the computer host to cover a slot of hard disk driver and a slot of CD-ROM disk driver of the front panel in normal times, and to be opened by being pressed down, when being used.

Abstract: A movable backrest for a chair comprises a frame that is fixed to the chair, at least a flexible connecting element connected to the frame, and at least a backrest connected to the connecting element. Since the connecting element is flexible, the backrest and the back of the user can be moved simultaneously along with the movement of the back of the user, providing a comfortable support to the back of the user.

Abstract: A paper shredder cutting tool having multiple cutting edges (-) constructed from a pair of cylindrical rotary cutters, which are each separately mounted on a polygonal shaft, and a plurality of cutting blades are securely mounted on the shafts. A paper guide is configured between each pair of adjacent cutting blades, thus partitioning the cutting blades therebetween, and thereby allowing the cutting blades to be assembled and mounted in an interleaving fashion on the two cylindrical rotary cutters. Moreover, each of the cutting blades is further constructed from a pair of blades. Having a plurality of cutting edges circumferentially arranged and minimally separated on each of the pair of blades, thereby forming a compact assembly of blade edges. The paper shredder cutting tool provides capability to feed around tens sheets of paper or cardboard at one time, thereupon being rapidly shredded into small bits.

Abstract: A light source device capable of repressing light surges is fixed in a flatbed scanner to provide a light beam for scanning a document. The light source device includes a bent lamp with bent parts for generating the light beam and compensating for the brightness at two ends of the bent lamp; and a set of obscuring units fixed at the two bent parts to partially obscure the light of the lamp. Hence, the light source device can repress the light surge caused on two ends of the image sensor even if the bent parts at two ends of the lamp are very close to the sides of the scanning window. Therefore, the length of the light source device can be shortened and the width of the flatbed scanner using the light source device can also be narrowed.
