A locking assembly for locking a portable electronic device to a work surface. The locking assembly comprises a clamp assembly including an elongated bar that extends between a first end and a second end. The clamp assembly further includes a first jaw and a second jaw moveable along the elongated bar for clamping to a work surface between the first and second jaws. A connector extends from a first connector end that is pivotally connected to the locking assembly to a second end that can be connected to the portable electronic device. The connector securing the portable electronic device to the work surface while permitting it to pivot with respect to the locking assembly.

A solid surface clamp that has a top jaw and a bottom jaw, along with alignment structures, is disclosed. The clamp includes a top jaw, a bottom jaw, a bolt attached to the bottom jaw and slideably received through the top jaw, and a nut. The bolt has an alignment cutout, a threaded portion extending from the top jaw and defines a bolt longitudinal axis. The nut is threaded onto the threaded portion of the bolt and transitions the clamp from an open position to a clamping position. The top jaw further includes an alignment hole that contacts the alignment cutout and maintains the top jaw and the bottom jaw substantially fixed relative to each other about the bolt longitudinal axis. The alignment cutout moves relative to the alignment shaft in the direction of the bolt longitudinal axis when the clamp transitions from an open position to a clamping position.

An anti-pivot and lock mechanism for a clamp including a horizontal post connected and moveable relative to a vertical post. The mechanism engages the vertical post and horizontal post above or below a pivot axis of the horizontal post to prevent or minimize pivoting movement of the horizontal post between changes of consecutive clamped workpieces.

An F-type clamp with an anti-pivot and lock mechanism that engages a side of the first post facing the clamp head below a pivot axis of the guide arm of the clamp; or the anti-pivot axis engages a second side opposite the first side and above the pivot axis of the guide arm.

A clamp for reinforcing a solid surface is disclosed and may be used with a top rail and a bottom rail. The clamp has a top jaw and a bottom jaw, each with a channel constructed to receive and align the top and bottom rails respectively in a first direction and a second direction. Each jaw has its own channel lip, shaft hole, and alignment pin hole. An alignment pin may be disposed of in the pin holes to inhibit the rotation of the jaws relative to each other. A shaft may be disposed of in the shaft holes, and the shaft may be at least partially threaded with a knob connected to the shaft. The clamp may have three configurations: a locked configuration; a sliding configuration; and a rail removal configuration. Multiple clamps may be used to construct a multidimensional frame to reinforce and support the solid surface.

A securing apparatus for securing a valve lever in a set position comprises a base body; a sliding piece; and a screw element, wherein the base body and the sliding piece each have a clamping surface; wherein the sliding piece is displaceably supported at the base body along a longitudinal axis; and wherein the screw element is rotatably supported at the base body and has a thread that is in engagement with a mating thread of the sliding piece so that a position of the sliding piece relative to the base body along the longitudinal axis is restricted to a maximum spacing between the clamping surfaces that can be changed by a rotation of the screw element in order to clamp the valve lever between the clamping surfaces. Depending on a rotational position of the screw element, a blocking receiver formed at the screw element is aligned with a blocking receiver formed at the base body so that a blocking element, in particular a cable, can engage into both blocking receivers in order to block the screw element in this rotational position.

The present disclosure relates to a gripper device which comprises: a belt pulley driven by a power-driven motor; a belt and another belt pulley driven by the above belt pulley; a ball screw driven and rotated by the belt pulley; nut brackets driven to be shifted along two rigid guideways by two reverse threads at both sides of the ball screw, respectively; a plurality of steel balls, which are installed between a nut bracket and a rigid guideway and sustain more stresses when a workpiece is clamped between two upper slide on the nut brackets.

A clamping device has a clamp surface with a base jaw and a countering jaw attached to a clamp surface. The base jaw has one or more through holes from its front base face to its rear base face so that a base accessory may be attached to the base jaw using the through holes in the base jaw. Likewise, the countering jaw also has one or more through holes from its front countering face to its rear countering face so that a countering accessory may be attached to the countering jaw using the through holes in the countering jaw. Because the clamping device has a plurality of through holes in the jaws, an accessory (such as a story stick) may be easily removably or fixedly attached to the face of either jaw by placing the accessory to the front face of a jaw and have pins or screws inserted through the rear face of the jaw to tighten the accessory onto the face of the jaw. There is no need to blindly matching the holes on the front face of a jaw with the holes on the accessory or drill a matching hole into the accessory prior to placing it on the jaw.

A vise is provided with a movable jaw including a threaded hole in a channel; an actuator in the channel and having a hole through an arcuate surface; a limit member in the channel and having front and intermediate cavities and a rear groove; a first plate member in the front cavity and having a through hole; a third plate member in the intermediate cavity and having a through hole; and a second plate member sandwiched between the first plate member and the third plate member and having a hole through a convex surface; and a slide sleeve including a tunnel, an intermediate thread engaging the threaded hole, a front annular flange in the rear groove, a front recess surrounded by the annular flange, and a biasing member in the front recess and urging against the third plate member; a handle; and a stationary jaw including a slide bar.

A clamp for reinforcing a solid surface is disclosed and may be used with a top and bottom rail. The clamp has a top and bottom jaw, each with a channel constructed to receive and align the top and bottom rails respectively in a first and second direction, respectively. Each jaw has its own channel lip, shaft hole, and alignment pin hole. An alignment may be disposed of in the pin holes to inhibit to rotation of the jaws relative to each other. A shaft may be disposed of in the shaft holes, and the shaft may be at least partially threaded with a knob connected to the shaft. The clamp may have three configurations: (1) a locked configuration; (2) a sliding configuration and (3) a rail removal configuration. Multiple clamps may be used to construct a multidimensional frame to reinforce and support the solid surface.
