A hand-held jack has a main body, including a frame on a grip, the frame having a shaft hole passing through a first chamber and a second chamber therein, a jacking member being fixed to a front end of the frame; and a slow-down device. The slow-down device includes a swing seat pushed by the first spring and mounted in the second chamber; at least one shaft clamp and at least one restricting plate urged by a third spring that are disposed in a first accommodating groove and a second accommodating groove of the swing seat for clamping a lift shaft; and an eccentric push member having an eccentric portion resting on the restricting plate and a push portion. When a workpiece is lifted by the hand-held jack, the slow-down device lowers the workpiece slowly.

Clamping clamp, in particular railing clamp, with a clamping arm and a fixed first clamping leg arranged on the clamping arm, and a second clamping leg which is displaceable along the clamping arm by means of a spindle, characterized in that at least one of the two clamping legs (5, 7) has a clamping element (12, 13) pivotably attached to the free end (5a, 7a).

Tools, systems, and methods of securing slabs, are described. Some example tools include a tool frame, a bracket, and an arm. The arm is adjustable relative to the tool frame and bracket into a slab-securing configuration in which an end portion of the arm is non-parallel with the bracket.

A work-holding device comprising a housing, at least one pin, a cover, and a flow regulation mechanism. The housing further comprising at least one chamber, the chambers having a first end, a second end, a fluid opening at the first end, and a pin opening at the second end. The pins having an actuating end and a base end. The pins are arranged in the chambers with the base end within the chamber and the actuating end extending through the pin opening. The flow regulation mechanism is attached to the cover and configured to regulate fluid flow into and out of the chambers.

The utility model relates to the technical field of flat steel rolling, in particular to a clamping and conveying mechanism suitable for flat steel rolling. According to the technical scheme, the clamping device comprises a base, mounting pieces, a driving motor, a mounting base and a clamping mechanism, the mounting pieces are fixedly connected to the two sides of the base, sliding rails are symmetrically arranged on the base, the mounting base is fixedly connected to the upper middle portion of the base, the mounting pieces are movably connected with a two-way lead screw on the mounting base, and the mounting piece on one side is fixedly connected with the driving motor; the output end of the driving motor is fixedly connected with a bidirectional lead screw, sliding seats are symmetrically and slidably connected to the sliding rail, and clamping mechanisms are arranged on the sliding seats. According to the device, the driving motor drives the bidirectional lead screw to rotate, so that the sliding seats on the sliding rails move relatively, the clamping mechanisms are driven to get close to or get away from each other, the top plate slides on the guide rails, the clamping plates are driven to rotate through the rotating frame to clamp and loosen flat steel, the reset springs provide reverse elastic force for loosening operation, and the limiting plate ensures that the flat steel is accurately positioned.
