Bee keepers, or apiarists, need to regularly inspect their hives in an apiary. In addition, the goal of the apiary is to collect products from the hive. To perform these maintenances chores, the bee keeper typically is required to remove a frame from the hive. Embodiments of the Bee Frame Extractor Grip are comprised of a pair of handles, a left-side grip assembly, and a right-side grip assembly. The pair of handles connect the left-side grip assembly and the right-side grip assembly via bolts that pass through the upper arms of both L-brackets and into the ends of the handles.

The clamping device according to the invention for clamping at least two processing devices for a sample preparation is made up essentially of at least three clamping blocks arranged in the axial direction, at least two of which are designed as movable clamping blocks, and a displacement mechanism for displacing the movable clamping blocks between an open position for inserting the processing devices, and a clamping position in which the at least two processing devices are clamped one on top of the other in the axial direction between two clamping blocks in each case. The displacement mechanism is designed for displacing the at least two movable clamping blocks in opposite directions.

The present invention provides an improved release mechanism for clamping tools where problems of thread slipping due to worn out thread can be reduced by the structure of a plunger with a small diameter section and the engagement of the thread shaft is made more secure by the cam action on account of the shape of the plunger. A protrusion extends from a push button on a top portion of the half-threaded nut. Threads are formed on an upper portion of the hole for engaging the threaded shaft. The middle portion of the plunger is made to have a section of small diameter allowing the protrusion to be pushed downward in a normal position and allowing the protrusion to rely on the resilient power of the helical spring to push it upward into the small diameter section.

The device (1) for locking workpieces on machine tools comprises:a base body (2) fixable to a machine tool (M) and provided with an oil hydraulic cylinder (3, 4, 5); 5a rod (8, 9) partly inserted in the oil hydraulic cylinder (3, 4, 5) slidably;roto-translation means (14, 15, 16) designed to divide the motion of the rod (8, 9) into:a first stretch (12) of roto-translation; anda second stretch (13) of translation; 10a clamp element (19, 20) associated with the rod (8, 9) and movable between:a home configuration;an intermediate configuration; andan operating configuration; 15at least a prismatic guiding body (21) associated with the base body (2) and prismatically couplable with the clamp element (19, 20) during the shifting of the rod (8, 9) along the second stretch (13).

The current invention relates to jig apparatus which is provided of a form to allow accurate positioning and repositioning of the same with respect to workpiece and the use of the jig apparatus to provide a guide for the provision of a drill bit through at least one guide passages therein to form a hole in the workpiece at a required location. In one embodiment the jig apparatus is provided in a form so as to provide a plurality of passages, each of which can be used as a guide for a drill bit to thereby allow a plurality of spaced apart drill holes to be formed in the workpiece without the need to move the jig apparatus with respect to the workpiece. In one embodiment guide means are provided which are selectively positionable by the user in order to allow the position of the jig apparatus with respect to the workpiece to be accurately defined and retained by the user.

The invention relates to a clamping device for clamping a workpiece, comprising a clamping element for clamping the workpiece; a rod having multiple radial slits disposed one behind the other in longitudinal direction of the rod, which each only extend along a partial circumferential area of the rod; a receiving device for receiving the clamping element and the rod; a longitudinal guide, within which the rod is disposed rotatably between a latching position and a release position; a locking mechanism disposed on the longitudinal guide, which does not engage with any of the radial slits in the release position such that the rod is movable in axial direction within the longitudinal guide, and engages with at least one of the radial slits in the latching position such that the rod is fixed in axial direction within the longitudinal guide. Furthermore, the invention relates to a processing table with a clamping device.

A pliers is provided, including a main body, a slidable member, a swingable assembly and a clamp assembly. The slidable assembly is attached to the main body. The swingable assembly includes a swingable member and a connecting member, and the swingable member is pivoted to one of two ends of the slidable member and one of two ends of the connecting member. The clamp assembly includes a first clamp portion and a second clamp portion, and the first clamp portion is disposed on the slidable member.

A feed/clamp apparatus includes a feed vise mechanism provided upstream from a cutting position, and a downstream vise mechanism provided just downstream from the cutting position. The feed vise mechanism includes first/second feed vise jaws, a downstream moving cylinder for moving the first feed vise jaw, and a downstream shifting cylinder for shifting the second feed vise jaw. The downstream vise mechanism includes first/second downstream vise jaws, a downstream moving cylinder for moving the first downstream vise jaw, and a downstream shifting cylinder for shifting a second downstream vise jaw. A vise surface of the second downstream vise jaw is located on one side of the vise reference position when the downstream shifting cylinder is located its stroke end on the one side. A thrust force of the downstream shifting cylinder toward the one side is made equal to a thrust force of the downstream moving cylinder toward another side.

The present disclosure is directed to a coupling assembly for a turbomachine. The coupling assembly includes a liner and a sleeve at least partially positioned circumferentially around the liner. A frame is positioned between the liner and the sleeve. The frame includes a first side wall, a second side wall, and a base wall extending from the first side wall to the second side wall. A block is positioned between the liner and the sleeve and is movable relative to the frame to permit the block to move toward and away from the base wall. Moving the block away from the base wall causes the block to exert an inward force on the liner and the base wall to exert an outward force on the sleeve.
