One end of the winding rod is manually rotated to make the winding rod drive the traction rope to rotate, and the traction rope pulls the clamp to move, and the metal with the wire drawing continuously passes through the rod hole, so as to obtain the metal wire of the required size.

[0016] Compared with the related art, the metal wire drawing device provided by the present invention has the following beneficial effects:

[0017] 1. Turn the turning handle so that the turning handle drives the small gear to drive the large gear to rotate, and the large gear drives the winding rod to rotate, and the winding rope is pulled by the winding rod to move, and the winding rope that bypasses the second steering wheel moves continuously, and multiple strands of winding ropes move together, so that the lower mounting frame drives one end of the traction rope to move continuously upward, and the traction rope drives the slider to move, thereby pulling one end of the metal wire to move. In this device, when manual power is input, the shaft rotated manually is the shaft of the small gear, and the large gear is driven to rotate through the small gear. The small gear serves as a power point. Due to its fast speed and small torque, it can more easily overcome friction resistance when driving the large gear. The large gear serves as a resistance point. Due to its slow speed and large torque, it can better withstand and transmit power, thereby ensuring the stability and reliability of the entire transmission system. In addition, in the transmission process from the small gear to the large gear, the torque is increased, which enables the entire transmission system to cope with the load more easily, thereby achieving a labor-saving effect.

[0018] 2. This device uses multiple fixed pulleys and multiple movable pulleys when pulling the traction rope. In the process of pulling the traction rope by winding the rope, since the winding rope alternately passes around multiple fixed pulleys and multiple movable pulleys, multiple strands of winding rope jointly undertake the work of pulling the traction rope, so that the staff can save more effort when turning the handle. Moreover, since the manual input end is a small gear, the large gear is driven to rotate by the small gear and the multiple movable pulleys cooperate with each other, thereby further achieving the effect of labor saving.

[0019] 3. The device is also provided with a power component when in use, which rotates the threaded ring. When the threaded ring rotates, the rotating ring drives multiple plug-ins to move in the sliding groove, and the multiple plug-ins are respectively moved into multiple slots. The first rotating shaft is driven to rotate by the rotation of the motor, and the second rotating shaft is driven to rotate by the belt. The second rotating shaft drives the fixed column to rotate through the plug-in block, so that the winding rod rotates to achieve traction of the winding rope. The two power input methods of manual and machine make the device have certain selectivity when in use, which is convenient for large-scale operations. When the motor is used to input power, the two ends of the plug-in block are respectively engaged in the sliding groove and the slot, and the inner wall of the slot squeezes the plug-in block, so that the plug-in block squeezes the sliding groove to achieve the rotation of the winding rod, which is more convenient to operate.
