The device is a multi-purpose drive socket capable of engaging both a penta-bolt and a hex-bolt. The device is specially adapted for use in the utility industry where multiple tools are typically needed for securing electrical equipment. The device contains a retractable plunger that slides in and out of the head opening. To remove a penta-bolt, the user simply presses the plunger head up against the head of the penta-bolt, causing the plunger to retract back into the socket body. Once fully inserted, the user can loosen or tighten the penta-bolt. To remove a hex-bolt, the user inserts the hex-head into a recessed opening in the plunger head and tightens down the hex-bolt until the hex-head breaks off at the shank. In the event the hex-head remains lodged in the plunger, the device also contains an ejector pin capable of dislodging and removing the hex-head.

A power tool includes an ejection mechanism configured to eject an end of a fastener. The ejection mechanism includes an ejection rod that is actuated by a motor of a power tool to move from a first position to a second position to eject the end of the fastener. Following ejection of the end of the fastener, the ejection rod is returned to the first position by a return spring.

An electric grinding tool includes a motor housing coupleable to an electrical power source, a motor configured to receive power from the electrical power source and including an output shaft extending along a motor axis, a handgrip coupled to and coaxial with the motor housing, a tool holder rotatably driven upon rotation of the motor, the tool holder configured to receive a shaft of a grinding accessory, and a light unit coupled to and at least partially recessed in a front end portion of the electric grinding tool. The light unit includes a plurality of lights mounted to an at least partially ring shaped printed circuit board that is received in a support ring, and a cover ring received over the lights.

A locking structure for a hand tool contains: a body having a driving head which includes an accommodation chamber and a rib, and between two ends of the rib is defined an opening. The rib has two positioning orifices, the accommodation chamber has an obliquely arcuate groove accommodating a ratchet member which has a toothed rim and two opposite apertures, and a part of each steel ball extends out of each aperture. The ratchet member further has a first trench, a polygonal groove, and a second trench. A cap is covered on the rib and includes a through orifice, an open section, a protruded section, an actuation extension, and two opposite openings so as to house two posts respectively, wherein a part of each post extends out of each opening, and a resilient element is defined between the second trench and the cap.

A tool includes a non-circular first engaging portion formed at the first end of a body, the first engaging portion has a first groove defined in the outside thereof. The first groove is located substantially at a middle portion of the first engaging portion. A second engaging portion is located at the distal end of the first engaging portion and has a second groove defined in the outside of the second engaging portion. The second groove is located close to the distal end of the second engaging portion. A function end is formed at the second end of the body. A passage is defined axially through the body.

A magnetic socket contains: a body and at least one magnetic attraction element. The body includes a connection segment and a fitting section, the connection segment has a polygonal coupling orifice defined therein and configured to accommodate a socket wrench, and the fitting section has a locking orifice formed therein and configured to lock a screw or a nut made of metal, wherein the locking orifice is polygonal. The body further includes at least one through orifice arranged on the fitting section and communicating with the locking orifice, and each of the at least one magnetic attraction element is housed in each of the at least one through orifice. Thereby, the magnetic socket is driven by the socket wrench so as to rotatably lock or remove a screw or a nut, and the magnetic socket magnetically attracts the screw or the nut, after removing the screw or the nut.

A clench wrench includes a structure defining a handle and an engaging head. The engaging head has a front side and a back side and includes an engaging space extending through the front and back sides. The engaging space defines an opening on both the front and back sides. A clenching device is mounted on the engaging head and includes a clenching member. The clenching member includes a clenching portion and is operable in a first mode in which the clenching portion is located at a first position capable of clenching the object engaged with the engaging head, and in a second mode in which the clenching portion is disposed away from the engaging space and is located at a second position capable of letting the object engaged with the engaging head disengage therefrom.
