A stapler comprises a base (1), a staple pin track (2), a top blade assembly (3), a hinge (4) and an upper cover (5). Tail ends of the staple pin track, the top blade assembly and the upper cover are all hingedly connected to a tail end of the base. A first guide part is disposed on a side wall of the upper cover, and one end of the hinge is slidably connected to the first guide part. The first guide part is set in a structure that when the upper cover is pressed, one end of the hinge can move to the tail end of the upper cover and press downwards. A second guide part is disposed on the side wall of the base, and the other end of the hinge is slidably connected to the second guide part. The second guide part is set in a structure that when the upper cover is pressed, the other end of the hinge can move to a front end of the base, and when the upper cover is opened, the other end of the hinge is separated from the base. A middle part of the hinge is hingedly connected to a middle of the top blade assembly, and the first guide part is close to the tail end of the upper cover. The present invention has a good labor-saving effect and makes it convenient to put in staple pins.

A staple device with an extension rod allows an installer to use the device to hold and pull tension on a string of wired lights and secure them to a surface, such as the underside of eaves or soffits on a dwelling. The activation of the stapling device is achieved by a pushing motion against the surface to be stapled to rather than the squeezing motion of current stapling devices. The staple device also provides greater mobility to the installer as opposed to the current method of positioning and repositioning a ladder around the base of the dwelling. The present invention allows the installer to quickly traverse the base of the dwelling and install the holiday lights in a more efficient manner than with the use of a ladder and squeeze-type staple staplers.

A fastener driving tool includes a housing, a striking member, an energy storing unit and a handle unit. The energy storing unit has a torsion spring which has weighted and driving legs extending from two ends of a coil. The driving leg is biased against and engaged with the weighted leg to be preloaded with a downward potential energy that urges a downward movement of the torsion spring and the striking member. The handle unit includes a handle and an anchoring member removably engaged with the striking member. When the handle is pivotally moved from a ready position to a striking position, the weighted leg is moved downwardly and the anchoring member and the striking member are moved upwardly to gradually increase a loading of the torsion spring for the striking member.

The present invention provides a multifunctional stapler including a housing, a nailing portion arranged at a front end of the housing, and a toggling device, a part of which being arranged inside the housing and a part of which extending to the outside of the housing. The nailing portion comprises: a staple feeding member arranged at a front end of the bottom of the housing, a staple feeding groove arranged on the surface at one side of the staple feeding member for receiving staples, a striking member, a part of which being inserted into the staple feeding groove, the toggling device controlling the striking member to strike the staples, and an adjusting device, a part of which being arranged outside the housing, for adjusting a depth of the staple feeding groove.

An extendible wire guide is slidably fitted at the front of a staple gun tool housing. An easily operated lever switch is linked to the wire guide to enable the wire guide to be deployed or retracted. The lever switch includes an up and a down position corresponding to a retracted and an extended position of the wire guide. The wire guide is resiliently biased, preferably toward the retracted position. The lever switch acts on the wire guide against the bias through a cam action on an upper edge of the wire guide. A bias spring is preloaded in a subassembly of the wire guide and bias spring for simplified final assembly.

A fastener driving tool includes a magazine unit, a handle, a striking plate, an energy restoring member and a wire bending spring disposed to a housing unit. The housing unit includes an inner housing assembly made from a plastic material, and an outer housing assembly made from a metal material and covering the inner housing assembly. The wire bending spring is biased for storing a striking energy for the striking plate, and includes an extending section and a backwinding section. The extending section has first and second ends. The backwinding section is connected with the second end, and extends and bends toward the first end to terminate at a terminal end portion. The ratio of a height to a width ranges from 1:1 to 1:1.6.
