The invention relates to a novel cable bridge which comprises straight grooves hinged to each other. The bottoms of the two straight grooves are connected and fixed through a connecting bottom plate, and the included angle between the two straight grooves is adjustable. A sliding block is arranged on the connecting bottom plate in a sliding manner, a boss is arranged on the straight groove, and a connecting rod is arranged between the sliding block and the boss. A vertically-through center guide groove is formed in the connecting bottom plate, a lead screw is rotatably arranged at the lower end of the connecting bottom plate, and the sliding block is slidably arranged in the center guide groove; the upper end of the sliding block is rotatably connected with the connecting rod, the lower end of the sliding block is in threaded connection with the lead screw, and an outer vertical plate is arranged between the side vertical surfaces of the two straight grooves. A vertically-through first sliding groove is formed in the straight groove, a vertically-through second sliding groove is formed in the connecting bottom plate, and a shaft pin is inserted in the crossed and overlapped position of the first sliding groove and the second sliding groove. The invention further discloses a cable corner adjusting method which can adjust the corner of the cable bridge and can meet the installation requirements under various use working conditions.

The invention discloses a numerically controlled machine tool capable of accurately locating workpieces, comprising a machine tool, a turntable is rotatably connected to the machine tool, an accommodation cavity is provided on the side of the turntable far away from the machine tool, and a support is vertically provided at the center of the bottom of the accommodation cavity The outer wall of the supporting column is provided with four groups of radial fixed rods at equal intervals, and the ends of the four groups of fixed rods away from the supporting column are all movably connected with telescopic rods, and the ends of the four groups of telescopic rods away from the fixed rods All of them are provided with a top plate, and the four groups of said top plates are provided with support plates on the side away from the telescopic rod, and the centers of the four groups of said support plates are all rotatably connected with threaded adjustment rods on the side away from the top plate, and the four groups of said support plates are Positioning baffles are arranged vertically on the outer sides, and the side of the positioning baffles away from the turntable is provided with a steel pipe installed on the outside of the support plate. The invention has the advantages of simple structure, convenient adjustment, wide applicability, accurate and stable positioning, and ensures the processing quality of products.

The invention discloses a strip-type tapping switch for a triangular three-dimensional wound iron core transformer, and belongs to the field of changeover switches. The strip-type tapping switch comprises a base, an adjusting mechanism and three tapping mechanisms, wherein the first tapping mechanism, the second tapping mechanism and the third tapping mechanism are respectively distributed at three corners of the same triangle; the first tapping mechanism comprises a first static contact assembly fixed on the base and a first movable contact assembly mounted on the first static contact assembly; the second tapping mechanism comprises a second static contact assembly fixed on the base and a second movable contact assembly mounted on the second static contact assembly; the third tapping mechanism comprises a third static contact assembly fixed on the base and a third movable contact assembly mounted on the third static contact assembly. The tapping switch disclosed by the invention is low in manufacturing cost, simple in lead wire structure and efficient in material saving for lead wire manufacturing; a wiring position can be close to a tapping wire of each coil of the triangular three-dimensional wound iron core transformer, and no lead wire clamps are needed on a device body.
