The invention discloses an electrical pole construction assisting mechanism for enlarging the distance between overhead conductor lines, and aims to provide the electrical pole construction assistingmechanism for enlarging the distance between the overhead conductor lines, which can reliably brace the two overhead conductor lines and provide an enough working space for a poling operation, and isconvenient to operate. The electrical pole construction assisting mechanism for enlarging the distance between the overhead conductor lines comprises a vertical stand pipe, a sliding sleeve, two tubular bracing rods, a connecting rod and linkage type conductor line holding mechanisms; the sliding sleeve slides along the vertical stand pipe; the two tubular bracing rods are distributed at two relative sides of the vertical stand pipe; the connecting rod is connected to the tubular bracing rods and the sliding sleeve; the linkage type conductor line holding mechanisms are arranged on the tubularbracing rods in one-to-one correspondence; the upper ends of the tubular bracing rods are hinged with the upper end of the vertical stand pipe; the linkage type conductor line holding mechanism comprises a connecting line, a tension spring, a guide sleeve and two semicircular hoop plates; the guide sleeve glidingly sleeves the tubular bracing rod; the two semicircular hoop plates are used for holding the overhead conductor lines; one hoop plate is fixed on the tubular bracing rod; and the other hoop plate is fixed on the guide sleeve.

The invention discloses an auxiliary opening device for pole setting operation, which aims to provide an auxiliary opening device for pole setting operation capable of stably and reliably opening twooverhead wires conveniently and quickly, and providing sufficient operating space for the pole setting operation of poles. The device comprises the following parts: a support tube, the first end surface of the support tube is provided with a fixed ring magnet, and the outer side of the support tube is provided with a first cable hanging groove that is close to the second end of the support tube; asliding rod, slidably provided in the support tube, wherein the first end of the sliding rod protrudes from the first end of the support tube to the outside of the support tube, the sliding rod passes through the fixed ring magnet, and a second cable hanging groove is arranged on the outer side of the sliding rod and on the outer side of the support tube; and a locking bolt, disposed on the support tube for fixing the sliding rod.

The invention relates to a cap liner feeding device. The cap liner feeding device comprises a cap liner feeding belt, wherein convex blocks for supporting cap liners are arranged on the cap liner feeding belt at equal intervals; a material receiving concave die is arranged above an outlet of the cap liner feeding belt; the material receiving concave die is used for carrying out receiving operationon the cap liners on the convex blocks; an assembling convex die is arranged beside the material receiving concave die; the assembling convex die is used for receiving the cap liners of the materialreceiving concave die and transferring the cap liners into an assembling die to be assembled; the material receiving concave die is used for carrying out the receiving operation on the cap liners on the convex blocks, so that the cap liners are guided into the material receiving concave die in a state that openings are upward; and when the cap liners and cap bodies are assembled, the assembling convex die is started and the cap liners are taken out from the material receiving concave die, so that the cap liners are guided into the cap bodies in the assembling die in an opening state, and furthermore, the assembling operation on the cap liners and the cap bodies is absorbed, and furthermore, the cap liners are guided out in the opening state, and the reliability of mounting the cap liners and the cap bodies is ensured.

The invention discloses a rotary overhead conductor opening device, and aims to provide the rotary overhead conductor opening device which can open two overhead conductors reliably, provides a sufficient operation space for vertical rod operation, and is convenient to operate. The device comprises a vertical pipe, a strip-shaped hole formed in the pipe wall of the vertical pipe and extending in anaxial direction of the vertical pipe, guide rings connected with the vertical pipe through connecting pieces and positioned above the vertical pipe, a sliding sleeve which slides along the vertical pipe, a sliding sleeve locking bolt arranged on the sliding sleeve, a pull rod arranged on the inner side surface of the sliding sleeve, two supporting rods distributed on the two opposite sides of thevertical pipe, and self-adaptive wire fixing devices arranged on the supporting rods in a one-to-one correspondence mode. The upper ends of the supporting rods are hinged to the upper end of the vertical pipe; the supporting rods are connected with the sliding sleeve through connecting rods; and one end of each connecting rod is hinged to the middle of each supporting rod, and the other end of each connecting rod is hinged to the sliding sleeve.

A conductor handling tool has a plate-shaped tool body (10). The tool body (10) comprises a conductor receiving opening (20) for receiving a conductor portion therein and for holding the conductor portion received therein. Further, an edge of the plate-shaped tool body is shaped convex as a tapered blade edge (12) extending essentially within a y-z-plane. The tapered blade edge (12) is directed away from the conductor receiving opening (20) and is forming an outer circumferential portion of the tool body (10) for splitting a portion of insulating material during winding of the insulating material.
