The invention discloses a grid shearing fixation device for a lead-acid storage battery. The device comprises a fixed base as well as a pressing plate fixation mechanism and a grid rib combing mechanism which are arranged on the fixed base, wherein the pressing plate fixation mechanism comprises a lower fixed plate, an upper fixed plate and a pressing plate driving mechanism, one of the upper fixed plate and the lower fixed plate is arranged on a first guiding mechanism which is arranged on the fixed base, and the upper fixed plate and the lower fixed plate are driven by the pressing plate driving mechanism and are closed under the guiding of the first guiding mechanism so as to clamp and fix a grid positioned between the upper fixed plate and the lower fixed plate; and the grid rib combing mechanism comprises an insertion assembly, a second guiding mechanism and an insertion driving mechanism, comb teeth which correspond to gaps between adjacent ribs on the grid one by one are distributed on the insertion assembly, the second guiding mechanism and the insertion driving mechanism are fixed on the fixed base, and the insertion assembly is arranged on the second guiding mechanism and is driven by the insertion driving mechanism to move along the second guiding mechanism, so that the comb teeth on the insertion assembly are inserted into the gaps between the adjacent ribs so as to limit the horizontal positions of the ribs of the grid.

A rotatable plug is mainly formed by pivoting a first base and a second base. The pivoting axis of the second base and the central axis of the first base form an included angle. When the second base rotates around the pivoting axis, the first base and the second base can achieve folding effect. A cable of the rotatable plug is connected onto a male connector, no terminal is required to be pivoted, the structure is simple, and safety is remarkably improved. When the second base rotates around the pivoting axis, cables in the first base and the second base are not twisted.

The invention relates to a connecting device for contacting electric machines (13), comprising a first electrically insulating insulator part (16) and a second electrically insulating insulator part (19), whereby a holder (22) is arranged between the two insulating parts (16) and (19). A conductive part (25) is separated from the support (22) and is connected to the second insulating part (19). The connecting device is characterised in that the first electrically insulating insulator part (16), the holder (22), the second electrically insulating insulator part (19) and the conductive part (25) are connected in a non-detachable manner.

The invention discloses a paper-covered copper strap wire bending tool, relates to the technical field of transformer repair and maintenance. The paper-covered copper strap wire bending tool is simplein structure and can be prevented from twisting when being bended. The paper-covered copper strap wire bending tool comprises a mother board and a cover board; the positive surface of the mother board is provided with a wire groove; the wire groove comprises a first transverse groove, a second transverse groove and a slanting groove; the slanting groove is arranged at the middle part of the mother board; the first transverse groove and the second transverse groove are arranged in the length direction of the mother board, are arranged on edges of the two sides of the mother board respectivelyand extend to the slanting groove from the two ends of the mother board respectively; the cover board is attached to the positive surface of the mother board and covers the wire groove; the cover plate is hinged to the mother board and is detachably connected with the mother board; and after the cover plate is rotated, the wire groove can be exposed. By adopting the paper-covered copper strap wirebending tool provided by the invention, a paper-covered copper strap wire is put in the wire groove, the mother board and the cover board press the paper-covered copper strap wire from the two sidesto ensure that the paper-covered copper strap wire cannot twist in a thickness direction, so that the paper-covered copper strap wire is prevented from twisting when being bended.
