Provided is an electric clamping device including a main body; a drive motor for providing a driving force; a driving force transfer portion for converting and transferring a magnitude of a driving force of the drive motor; a sliding crank having one side connected to the driving force transfer portion and for converting a rotational motion of the driving force transfer portion to a reciprocating motion; a toggle link having one side connected to the other side of the sliding crank and including an elastically deformable link; and a clamp having one side connected to the toggle link and having the other side for clamping or unclamping an object. Various other embodiments are available.

A clamp of a bicycle workstand includes a base, an elastic unit, an operating arm, a link unit, and a clamping unit. The base has an accommodating trough. The elastic unit has a shaft sleeved with a spring and a slide and disposed in the accommodating trough. The clamping unit has a fixed clamp body disposed on the base, and a movable clamp body pivotably connected with the base and the operating arm. The link unit has a first link and a second link pivotably connected with each other and pivotably connected with the operating arm and the slide respectively. The second link has a cam. Pulling the operating arm can drive the first and second links to swing. The cam is abutted on the shaft and presses it by rolling. The fixed clamp body and the movable clamp body can be coupled for stable clamping.

A clamp assembly for securing a workpiece to a cutting machine having a plurality of slats is set forth. The slats have a depth and a space between the plurality of slats have a width. A base has a first surface and a second surface opposite the first surface. An elongated extension has a first end coupled to the base and a second end having a flange wider than the width. A clamping mechanism is coupled to the base. The clamping mechanism has a compliant stopper movable from a clamping position and an open position.

A clamping apparatus is provided with: a metallic detector that is provided to a pivot shaft pivotally moving integrally with a clamp arm under the operation of a driving unit, in such a manner as to extend along the pivot shaft so as to be around the axis thereof; and one proximity sensor that is arranged so as to be opposed to the detector and that detects the magnetic loss of the detector. The detector is formed so that the area of a sensor opposing part opposed to a detection surface of the proximity sensor changes in association with the pivotal moving of the pivot shaft.

A flag for securing a work piece to an assembly jig comprises a base. At least one positioning member extends outwardly from the base for selectively pivoting about at least one axis. An end effector is connected to the at least one positioning member and defines an interaction point for engaging the work piece. A joining connection secures one of the at least one positioning member to another of the at least one positioning member. The joining connection has a first configuration and a second configuration. One of the at least one positioning member is moveable relative to another of the at least one positioning member in the first configuration. The joining connection defines at least one bore for receiving a dowel to secure one of the at least one positioning member to another of the at least one positioning member to lock the interaction point in the second configuration.

A table tennis assembly apparatus is provided. The table tennis assembly apparatus may provide a base substrate and an overlaying cutting substrate. Along at least one peripheral of the base substrate may be a bar panel and or one or more clamps. Each clamp is for urging a first force distributor to sandwich a table tennis blade, in a uniform manner, against a glued table tennis rubber supported by the base substrate. After a predetermined amount of time a user may swap the first force distributor for a smaller second force distributor, enabling the user to trim the table tennis rubber around the perimeter of the blade.

An angle element for a welding and clamping table system includes an L-shaped profile, a base plate releasably fastened at one end of the L-shaped profile and provided with a system borehole of the welding and clamping table system, and a member releasably fastened at another end of the L-shaped profile and selected from the group consisting of a further such base plate and a clamping plate which is provided with several threaded boreholes to accommodate various hole patterns of quick-change clamps.

Embodiments of the current invention relate to a pliers wrench. Optionally, the jaws of the pair of pliers lock to an adjustable gap size and/or the gap between the jaws is aligned with a rotational axis of the pair of pliers. For example, there may be two jaws that adjust symmetrically around the rotational axis. In some embodiments, each jaw is closed toward an opposing jaw by a lever. Optionally, a locking mechanism locks the jaw when it reaches half the gap width from the rotational axis. Optionally, each jaw is closable independently of the other jaw. Optionally, a notch in the jaws forms an angle for clasping a bolt perpendicular to an axis of the device. For example, the notch may have a 120 angle.
