A clamping unit includes a case with a contact surface, an operation member arranged movable in a pressing cancellation direction and a pressing promotion direction relative to the case, a pressing body arranged in a movable manner in the case to oppose the contact surface, and a movable body between the pressing body and contact surface. At least one of the contact surface, movable body, and pressing body includes an inclined surface. The inclined surface increases a protruding amount of the pressing body from the case when the movable body changes in position as the operation member moves in the pressing promotion direction and eases pressing of the movable body against the pressing body when the movable body changes in position as the operation member moves in the pressing cancellation direction to permit a decrease in the protruding amount of the pressing body from the case.

A connector and a frame structure using the same, wherein the connector at least comprises a socket, a bolt and an expansion bolt; the socket comprises a connection end, and a slot, which extends along a length direction of the socket from an end surface of the connection end, is provided on the socket; the bolt comprises a bolt main body that is adapted to the slot, a front end of the bolt main body is provided with at least two expansion arms, and the bolt main body is internally provided with an expansion channel which traverses the bolt main body along a length direction; and the expansion bolt comprises an expansion bolt main body that matches the expansion channel, a front end of the expansion bolt main body is provided with an acting end that interacts with the expansion arm, and the socket and the bolt are tightly connected by means of an expansion force that is generated by the acting end opening the expansion arms. The aforementioned connector achieves quick disassembly and assembly, and also has the advantages of reliable connection, convenient disassembly and assembly and long service life.

A device for retaining a printed circuit board module in a mounting groove of a cold plate, the device comprising an elongated housing made of metal, which has a cross-section in the shape of a horizontal U. A pressure piece made of metal is mounted in the housing so as to be displaceable transversely relative to the rotational axis of the housing and comprises a flat clamping surface on the front side. A rotary cylinder can be rotatably mounted in the housing so as to be transversely displaceable relative to the rotational axis. During a rotation, eccentric guide elements can be used to effect a forward displacement of the rotary cylinder. The pressure piece follows the displacement of the rotary cylinder and slides outward. The waste heat of the printed circuit board module is transported via the housing and the pressure piece to the cold plate.

The coupling device (1) comprises a clamping fixture (2) fixable to a manipulator and an adapter (40) securely clampable thereto. Both the clamping fixture (2) and the adapter (40) are configured substantially rectangular. The clamping fixture (2) comprises a locking mechanism (5) consisting of two laterally shiftable locking elements (6, 7) and an actuating member (8) disposed inbetween. For fixedly securing the adapter (40) to the clamping fixture (2) the locking elements (6, 7) are urged by means of the actuating member into the side widenings (45, 46) of the locking opening (44). In addition, the clamping fixture (2) is provided with a slotted recess (4) and the adapter (40) with an elongated base (41), the latter being insertable into the slotted recess (4).

Connection device for two furniture parts which have to be interconnected, with a first connection portion which is realized at least as a spreading system and which is intended for being provided in a recess in a first furniture part, with a second connection portion which is intended for extending outside of the recess for cooperating with a second furniture part in this manner, as well as an activation mechanism for activating the spreading system, wherein the spreading system comprises at least two mutually rotatable parts, a first part and a second part, respectively, wherein the mutual rotation of which, in function of the realized mutual angle position, effects a spreading effect.

A quick release clamp assembly for use with a pole. The clamp has a clamp body, a connecting member extending between first and second ends of the clamp body, an actuator connected to one end of the connecting member. The other end of the connecting member is connected to one end of the clamp body by a resilient mount. Closing the actuator moves the two ends of the clamp body towards each other, exerting redial force on the pole.
