An electric stapler is operated by a paper bundle pinching step of relatively moving a table part and a driver unit and also pinching a paper bundle; a staple separation step of folding a staple into U-shape by a forming plate and also separating the folded U-shape staple from a staple sheet by moving a driver; a penetration step of penetrating legs of the staple into the paper bundle by further moving the driver; a clinch step of inward folding the legs by a clinch device; and a paper bundle releasing step. A relative movement of the table part and the driver unit, the forming plate, the driver, and the clinch device are powered by a single motor. A driving speed of the motor in the steps excluding the penetration step and the clinch step is slower than the driving speed of the motor in the penetration step and the clinch step.

A tool for gripping and removing mechanical fasteners such as pedicle screws. With reference to FIG. 7, the device generally resembles a screwdriver, having a handle on one end, a long shaft in the middle, and fastener engaging means on the other end. The fastener engaging means comprises a set of two or more jaws having inward facing gripping surfaces positioned to grasp the external surfaces of a screw head. The jaws are formed as part of a collet slidably mounted within an outer thread sleeve. The thread sleeve is attached to the shaft. A tapered journal on the collet interacts with a tapered bore in the thread sleeve so that when the collet is pulled into the thread sleeve, the set of two or more jaws are squeezed together. The threaded engagements between the collet and the thread sleeve should be the reverse of the thread on the screw to be removed; i.e., if a right-hand screw is to be removed then the threaded engagement between the collet and the thread sleeve should be made with a left-hand thread. In operation, the jaws are placed over the screw head and the device is rotated in a counterclockwise direction (for removal of a screw with a right-hand thread). The inward facing surfaces on the jaws bear against the bolt head, thereby impeding the rotation of the collet relative to the thread sleeve. The left-hand threaded engagement between the collet and the thread sleeve therefore pulls the collet further into the thread sleeve, whereupon the tapered bore squeezes the jaws more tightly together. Thus, the reader will appreciate, applying torque to the device when it is in position on a screw head simultaneously torques the screw head and squeezes the jaws more tightly together. The inward facing surfaces are also provided with an undercut in order to accommodate axial misalignment between the jaws and the screw head.

A hand-held drive-in tool for driving fastening elements in a workpiece and including a guide (12), a drive-in ram (13) displaceable in the guide (12) for driving a fastening element in, a drive-in unit (30) for driving the drive-in ram (13) and including at least one first drive spring (31) and at least one second drive spring (32) having respectively, opposite first and a second expansion directions (37, 38), and a tensioning device for preloading the drive-in ram (13) and the first drive spring (31).

A setting device (10) for driving fastening elements into a receiving material has a housing (11), with a muzzle part (20) which is displaceable axially relative to the housing (11) and is arranged with a guide channel (38) for a fastening element strip (50) and opens into a receiving space (39) for a fastening element (51) to be driven in. Further, a locking element (30) is arranged in the muzzle part (20). The locking element (30) has a feeler portion (33) for detecting a fastening element (51) in the receiving space (39) and a locking part (32) for blocking the displacement of the muzzle part (20) relative to the housing (11) in a locking position (61) when a fastening element (51) is not detected in the receiving space (39) by the feeler portion (33). A blocking member (40) in the muzzle part (20) is movable into the guide channel (38) so as to block the fastening element strip (50). To improve a setting device (10) of this type, the blocking member (40) is in an operative connection with the locking element (30) so that the blocking member (40) can be actuated by the locking element (40).

A positioning device of a nail driver comprises a tool body; a positioning unit in a front end of the tool body; the positioning unit having a nail output frame and a guide block formed by two sliding blocks; an nail output opening at a front end of the nail output frame formed with two sliding recesses; the two sliding blocks being movable installed into the sliding recesses; a guide opening formed between the two sliding blocks; when the two sliding blocks are separated, the guide opening expands; two positioning plates; each of two sides of the nail output frame having a respective one of the two positioning plates; and two spring elements, each spring element being confined by a respective one of the two positioning plates and a respective one of the two sliding blocks.

A tool for driving and setting nail-pin anchors and anchor bolts into concrete, the tool using the percussive action of a rotary hammer drill. The tool comprises a body member with a spring, a driver, and a ram inserted into the body member's bore. After a hole is drilled for insertion of the anchor, the masonry drill bit of the rotary hammer drill is slid inside the bore of the ram and temporarily locked to the tool. The rotary hammer drill is activated, and the drill bit turns inside the ram without affecting the body member or the anchor. Instead, the percussive force of the rotary hammer drill transfers its impact to the ram and the driver, which impacts the nail of the nail-pin anchor, or the stem of the anchor bolt, setting it into the concrete. A keyed bearing can be installed inside a sleeve of the ram in order to protect the tip of the masonry drill bit from shearing.

Three congruent prongs (16A, 16B, 16C) mounted on a shaft tube (12), converges simultaneously when an operating sleeve (14) moves forward. This action, along with their notches and shape provides a firm grip for holding and starting nuts and bolts. These prongs, made out of 304 grade stailess steel bands, provide good spring-like flexibility and rigidity. The concave sides of the prongs mate with the outside surface of the shaft tube (12) every time the operating sleeve (14) is moved forward. These physical features provide consistent alignment of the prongs every time the tool is used. With rubber sealant (16D) coated on the inside surface of the prongs, the nut and bolt starter gives a firm grip to hold and start a wide variety of shapes and sizes of screws, nuts and bolts. Additional uses of this tool are done with the prop rod (20) supplementing the prongs. More versatility of this instrument is derived from the prop rod (20) using nuts of the same thread pattern to position flat washers and lock washers into their threaded studs. Furthermore, the socket extension receiver (30) provides a convenient extra-reach supplement whenever needed.
