Abstract: An injection molding device includes a female mold defining a cavity, a male mold having a projecting part protruding toward the female mold corresponding to the cavity, a transport configured for transporting a foil into a position between the female mold and the male mold, a vacuum-pump, and a thermal medium source. A plurality of air discharging holes is defined in the female mold joining in the cavity. A channel is defined in the projecting part of the male mold. The vacuum-pump is connected to the air discharging holes of the female for vacuuming the cavity to suck the foil toward the female mold. The thermal medium source is connected to the channel of the male mold for inputting thermal medium into the mold via the channel to press the foil to cling to the female mold.

Abstract: A stapler includes a main body, a striking plate, a trigger plate, an elastic plate, a top cover, a restoring spring, a base, and a safety device. Thus, the positioning portions of the elastic plate have the same size and the same bent angle to provide a force which is distributed on the striking plate evenly to drive the striking plate to perform the stapling action exactly and smoothly, thereby enhancing the stapling efficiency of the stapler. In addition, when the base is detached from the main body, the top cover is locked by the positioning block to prevent the top cover from being pressed unintentionally so that the striking plate will not be triggered by pressing the top cover so as to protect the user's safety.

Abstract: A file carrying device includes a carrying assembly having a plurality of connecting boxes connected with each other, and a plurality of files mounted on a respective one of the connecting boxes of the carrying assembly. Thus, each of the files is locked on and detached from the respective connecting box of the carrying assembly, so that each of the files is arranged easily and conveniently, thereby facilitating a user arranging each of the files. In addition, each of the files contains documents therein so that the each of the files can protect the documents to prevent the documents from being missed.

Abstract: A pliers type stapler includes a case assembly, a magazine, a trigger mechanism, and a push mechanism. The case assembly includes a first handle, a metallic plate, a striking plate, and a second handle. The trigger mechanism includes a pivot member, and a torsion spring. Thus, the striking plate is lowered from its uppermost position to staple the article to be stapled instantaneously so that the striking plate has greater impact stroke and strength to staple the article efficiently without incurring deflection, thereby enhancing the stapling effect and quality of the stapler. In addition, the stapler is operated like pliers, so that the user can operate the stapler conveniently, thereby saving the manual work.

Abstract: A pliers type stapler includes a case assembly, a magazine, a seat board, a striking plate, a trigger mechanism, and a push mechanism. Thus, the striking plate is lowered from its uppermost position to strike the staple to staple the article to be stapled instantaneously so that the striking plate has greater impact stroke and strength so as to staple the article efficiently without incurring deflection, thereby enhancing the stapling effect and quality of the stapler. In addition, the stapler is operated like pliers, so that the user can operate the stapler conveniently, thereby saving the manual work.

Abstract: A stapling device includes a housing pivotally attached to a base member and having a channel for receiving staples, a staple drive plate slidably received in the housing and movable to drive the staples, a staple pushing device includes a casing slidably engaged in the channel of the housing and a pusher for forcing the staples forwardly toward the staple drive plate, and an actuating device for actuating the staple drive plate to drive the staples. The staple pushing device may be easily and readily assembled into the housing, and includes a projection or protrusion for detachably anchoring the staple pushing device to the housing.

Abstract: A corner trimming device includes a base, a placement seat secured on the base, an anvil secured on the placement seat, a pivot seat pivotally mounted between the base and the placement seat, a trimming blade secured in the pivot seat to move therewith and movable relative to the anvil, and a restoring spring mounted between the base and the pivot seat to provide a restoring force to the pivot seat. Thus, the restoring spring and the elastic plate provide a restoring force to the pivot seat to restore the press portion and the trimming blade to the original state, thereby facilitating a user operating the press portion to trim the corner of the paper.

Abstract: A stapling device includes a housing pivotally attached to a base member and having a channel formed by a partition, a staple drive plate slidably received in the housing, a staple magazine slidably engageable in the channel of the housing and having a front staple drive space. A staple feeder is engaged into the staple magazine and includes a spring-biased pusher for forcing staples forwardly toward the staple drive space of the staple magazine, and for allowing the staples to be driven by the staple drive plate, and an actuating device for actuating the staple drive plate to drive the staples. The staple magazine may be easily disengaged from the housing from a rear inlet of the housing.

Abstract: A number lock device, comprising a lock housing, a lock core, a cable, a cover, a movable member, a driving member, a locking plate, and a locking pin. Thus, the number lock device can be operated by the user's one hand only, thereby facilitating the user operating the number lock device. In addition, the correct numbers of the number rings of the lock core of the number lock device can be changed easily and conveniently.

Abstract: A rotatable book holder includes a housing having a chamber to rotatably receive a rotary member which has a number of holes. A pole includes a lower portion secured to the rotary member, and a plate is secured to an upper portion of the pole and includes a number of holes facing toward the holes of the rotary member, to receive shanks of books, and for allowing the books to be rotated relative to the housing in concert with the rotary member, and thus for allowing the books to be easily viewed or read by the users. The housing includes a weight to rotatably support the pole and to increase stability of the housing.

Abstract: An adjustable book holder includes two primary frames, and one or more auxiliary frames selectively secured between the frames, to increase holding of more books or sheet members to the book holder. The primary frames and the auxiliary frames may be secured together with peg-and-aperture engagements. Two followers may be attached to the frames, and may be coupled between the primary frames and the auxiliary frames, and may be rotatably or adjustably secured to two seats, with gear engagements, to allow the followers and the primary and the auxiliary frames to be secured to the seats at selected angular positions.
