Description

Technical Field

[0001] The utility model relates to the technical field of wire threading machines, and more particularly to a wire threading machine for electrical installation. Background Art

[0002] The threading machine for building electrical installation is a machine used to thread cables and wires for electrical installation in the construction industry. The threading machine first passes the pulling wire into the interior of the electrical pipe, then connects the electrical line to the end of the pulling wire, and then pulls the pulling wire. The threading operation of the cables and wires for building electrical installation is achieved through the action of the pulling wire.

[0003] After searching, the existing patent (Announcement No.: CN221380261U) discloses a wire threading machine for electrical installation. During use, the machine is provided with a drive motor, a drive shaft, a gear, a rotating column, a connecting column, a mounting ring and a wire outlet tube. When in use, the wires in the wire outlet tube are pulled out and then inserted into the wire tube. Then, the drive motor is started to drive the drive shaft to rotate, which drives the gear to rotate, which drives the rotating column to rotate, and drives the connecting column and the mounting ring to rotate, pushing the internal wires out and allowing the wires to advance in the wire tube, thereby achieving the function of threading. The advantage is that the wires can be automatically arranged by the drive motor. However, in the process of realizing the present invention, the inventor found that the prior art has the following problems: When the above-mentioned wire threading machine for electrical installation is performing the threading operation, the wires are passed from the inside of the wire outlet tube to the inside of the external wire tube. However, due to the fixed height and angle of the wire outlet tube, when the wires are passed into the external wire tube, the two cannot be linearly adapted, resulting in the wires being bent during the threading process, which increases the difficulty of threading.
