The present invention relates to a shredder having a thickness triggering device. During the shredding operation, the trembling of the article is minimized or eliminated by using the shredder. The shredder includes a sustaining mechanism and a driving assembly. Since the sustaining mechanism is sustained against the shredding article, the amplitude of the trembling article is largely reduced. As a consequence, the influence of the shredding article on the thickness triggering device is reduced so as to prevent interruption of the shredder.

Shredder

A cutting apparatus includes a motor, a gear set, a gliding block, a rotating shaft and a handling element. The gear set includes a first gear part connected to the motor and a second gear part connected to a protrusion member. The center line of the protrusion member is shifted from the center line of the second gear part. The gliding block includes a gliding channel for receiving the protrusion member therein. The protrusion member is linearly moved along the gliding channel back and forth when the protrusion member is rotated in a circular motion. The rotating shaft is connected to an end of the gliding block such that the rotating shaft is rotated with synchronous linear movement of the protrusion member. The handling element has a first end sheathed around the rotating shaft and a second end operated to have the cutting member linearly moved along two guiding tracks.

Cutting apparatus

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.

Stapling device

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.

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.

Automatic start mechanism of shredding apparatus

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.
