Abstract: A punch includes a first member and a second member which has two lugs extending therefrom which are pivotally connected to the first member. Two apertures are defined through the second member. A transverse frame is connected between the two lugs and two punching tools movably extend through the transverse frame. Each punching tool has the first end thereof contacting the underside of the first member and the second end of each punching tool extends through the transverse frame and is located in alignment with the aperture corresponding thereto. A first end of a rod rotatably extends through the second member and the first member, wherein a second end of the rod movably extends through the second member. A handle is pivotally connected to the first end of the rod so that the handle is pivoted relative to the first member to extend the distance between the punching tools and the handle.

Abstract: A stapler includes a base with a magazine and an arm respectively connected to the base. A positioning plate is received in the magazine and a first spring connected between the positioning plate and the magazine. A pusher is slidably engaged with the positioning plate and a connection plate is connected to the pusher. The connection plate is slidably connected between the arm and the magazine. A protrusion extends from the magazine and a positioning hook extends from the positioning plate so that a second spring has one end connected to the pusher and the second spring goes around the protrusion on the magazine, and the other end of the second spring is engaged with the positioning hook. The second spring will not be exposed when loading staples and the second spring does not occupy the space of the magazine.

Abstract: A stapler includes a base with an operation arm pivotally connected to a frame extending from the base. A first magazine and a second magazine which is received in the first magazine are pivotally connected to the frame so that the staples with small size can be received in the second magazine and the staples with large size can be mounted between the two magazines. A staple follower includes an inner portion to push the staples with small size and an outer portion to push the staples with large size. The stapler employs either one of two staples having different sizes.

Abstract: A stapler includes a base, a pusher, a main plate, a handle plate and a handle. The handle plate has two hook elements defining a slit and a U-shaped second spring engaged between said two hook elements to urge them apart to engage to an ejector. The main plate is received in the pusher and has a projection extending downward therefrom to insert into a hole defined in a bottom of the pusher so as to define a slot between the main plate and the pusher in one end.

Abstract: A stapler includes a pair of walls disposed in parallel in a top so that a space is formed between the walls, one or more ribs are formed in the space, and a punching element force-fitted in the space and force-fitted between the ribs such that the punching element is stably retained in place.
