Abstract: A stapling device for binding an article having a hole structure with a stapling medium having a loop structure corresponding to the hole structure is provided. The stapling device includes a supporting portion, a movable portion and a transmission portion. The supporting portion is used for holding the stapling medium. The movable portion is disposed adjacent to the supporting portion and moved in a first direction to sustain against the loop structure and in a second direction to prop open the loop structure after the stapling medium is held by the supporting portion, thereby allowing the open loop structure to hook in the hole structure of the article. The transmission portion is coupled to the movable portion, and transmits the movable portion to move in the first direction and the second direction in response to a force exerted thereon.

Abstract: A hole punch has a length in a first direction, a plurality of punch blocks each having a sinusoidal first guide surface, a slider movable along a frame in the first direction, and a roller connected to the slider at a position to engage the first guide surface of each punch block. Each punch block is fixed in the frame in the first direction and is moveable in the frame in a second direction perpendicular to the first direction. Each punch block also includes at least a punch head facing the second direction, and a retracting mechanism for urging the punch block in opposite the second direction to an initial position. When the slider moves in the first direction along the frame, the roller pushes the first guide surface near the middle of the punch block moving the punch block in the second direction to punch holes.

Abstract: A punching apparatus includes a platform for placing thereon an object to be punched, a rail body coupled to the platform and having two oppositely arranged rail elements and a cutting-pin receiving space between the two rail elements, a cutting tool including a plurality of cutting pins movably installed in the cutting-pin receiving space, a sliding member slidable along the rail body, and a first sustaining member disposed between the rail elements and carried by the sliding member for sequentially forcing the cutting pins to protrude toward the platform, thereby creating through holes in the object.

Abstract: A punching apparatus includes a base, a punching structure, a transmitting shaft and a handle member. The base is used for placing thereon an object to be punched. The punching structure is mounted over the base for digging into the object to create at least one hole. The transmitting shaft is coupled to the punching structure and rotated to actuate the punching structure to move between a punching position and a releasing position in response to first and second external forces, respectively. The handle member is attachable to and detachable from any of a first end and a second end of the transmitting shaft, and transmits the punching structure to move between the punching position and the releasing position in response to the first and the second external forces exerted thereon, respectively.

Abstract: A punching apparatus includes a base having thereon a plurality of seats for receiving and holding an object to be punched; an eccentric transmission mechanism disposed on the base and performing a uni-directional eccentric rotation; and a cutting tool assembly transmitted by the eccentric transmission mechanism to alternately switch between a working state where a plurality of cutting tools thereof are moved deep into the seats to punch through the object and a standby state where the cutting tools are retracted from the seats to release the object in response to the uni-directional eccentric rotation.

Abstract: An actuation device includes a first signal generator, a first signal receiver and a signal discriminator. The first signal generator generates a first signal in a first preset pattern. The first signal receiver is used for receiving the first signal. The signal discriminator is electrically connected to the first signal receiver to determine whether the first signal receiver receives the first signal in the first preset pattern, and asserts an actuation signal to actuate a punching operation of the punching apparatus when the first signal is interrupted from the first preset pattern.

Abstract: A punch pin structure includes a pin body, a first piercing end, a second piercing end and a cutting member. The first piercing end extends from the bottom of the pin body. The second piercing end extends from the bottom of the pin body and is separate from the first piercing end. The cutting member is disposed at the bottom of the pin body between the first piercing end and the second piercing end. The first piercing end is in contact with the object to be punched prior to the cutting member and the second piercing end in response to a punching operation.

Abstract: An automatic start mechanism for a shredding apparatus is disclosed. The shredding apparatus includes a shredding mechanism for cutting the paper when the paper passes through a channel, a power source for outputting a motive power for the shredding mechanism, a trigger disposed at an entrance of the channel for arising a move when the paper passing through the channel to be against thereto, a delay unit for producing an against force driven by the power source, a lever connected between the trigger and the delay unit for moving in response to the trigger and the delay unit against, and a switch electrically connected to the power source and contacted to a first portion of the lever. The distance between the first portion of the lever and the trigger is smaller than a distance between the delay unit and the trigger.

Abstract: A punching apparatus includes a main body, a sustaining structure and a non-linear levering rod. The main body is used for receiving therein the article and exerting a punching force on an article to punch holes. The sustaining structure is used for transmitting a depressing force to the main body by depressing the main body to provide the punching force in response to an external force. The non-linear levering rod comprises a force-receiving portion, a pivot portion and a bent portion. The force-receiving portion is applied thereonto the external force. The pivot portion is coupled to the main body for allowing the levering rod to pivot relative to the main body in response to the external force. The bent portion is connected to the force-receiving portion and the pivot portion for keeping the force-receiving portion at a substantially horizontal level in a rest state.

Abstract: The present invention provides a shredder, which has a housing, an entry slot on the housing for inserting a desired medium, a shredding device installed inside the housing for shredding the medium, and a central trigger for sensing the medium and therefore triggering the shredding device. The shredding device has a shredding gap between two shredding knives. The central trigger is installed above the central portion of the shredding gap. The shredder further has a side trigger installed between the central portion and an end of the shredding gap. When a large medium is inserted into the entry slot, the medium will trigger the central trigger device and therefore trigger the shredding device. However, when a sufficiently short medium is inserted into the entry slot, the medium is capable of triggering only the side trigger, and therefore triggers the shredding device.
