[0025] Refer to the attached Figure 1 and 2 As shown: This embodiment discloses a threading machine for quickly replacing leads, comprising a housing 1, a lead reel 2 installed in the housing 1, and a lead 3 movably installed in the housing 1 and driven by a driving device to be received in the lead reel 2 or extended from the housing 1; the tail end of the lead 3 is received in the lead reel 2 of the housing 1, and the head end of the lead 3 is used to connect with the threading line. When in use, the lead 3 is first driven by the driving device to extend out of the housing 1 and the lead reel 2, and the head end of the lead 3 is passed from one end of the pipe to be threaded until it passes out from the other end of the pipe; at this time, the line to be passed into the pipe is wound and fixed on the head end of the lead 3, and then the lead 3 is driven by the driving device to be retracted into the housing 1 and the lead reel 2, and then the line fixed at the head end of the lead 3 is pulled into the pipe;

[0026] Specifically, Figure 7As shown, the driving device in this embodiment includes a friction wheel assembly 10 installed in the housing 1 and driven to rotate by a motor, and a synchronous belt assembly 11 connected to the friction wheel assembly 10 in transmission. The lead wire 3 is clamped between the friction wheel assembly 10 and the synchronous belt assembly 11 and moves in a directional manner driven by the friction wheel assembly 10 and the synchronous belt assembly 11. In this embodiment, the lead wire 3 is clamped between the friction wheel assembly 10 and the synchronous belt assembly 11, and the friction wheel assembly 10 is driven to rotate by the motor, so that the lead wire 3 moves in the corresponding direction under the friction force of the friction wheel assembly 10 and the synchronous belt assembly 11, thereby realizing the lead wire 3 extending into and out of the housing 1.

[0027] The friction wheel assembly 10 and the synchronous belt assembly 11 in this embodiment can adopt the friction wheel assembly and the synchronous belt assembly in a threading machine with patent publication number CN217522485U; specifically, Figure 8 As shown, the friction wheel assembly 10 in this embodiment includes a lead reel 10-1, a friction wheel 10-2, a driving gear 10-3, a gear seat 10-4 and a passive gear 10-5.

The driving pulley 11-5 is transmission-connected with the passive gear 10-5. In this embodiment, the driving pulley 11-5 and the passive gear 10-5 are fixedly installed on the outside of the same rotating shaft. The driving gear 10-3 is driven to rotate by a motor. The driving gear 10-3 rotates to drive the friction wheel 10-2 to rotate, and at the same time drives the passive gear 10-5 and the driving pulley 11-5 to rotate, thereby driving the synchronous belt 11-2 to move in the corresponding direction, so that the lead 3 clamped between the friction wheel 10-2 and the synchronous belt 11-2 moves in the corresponding direction under the action of friction.

[0030] Furthermore, the housing 1 is provided with a wire outlet 7 connected to the cavity, and the inner side of the wire outlet 7 is provided with a wire outlet socket 8 connected to the cavity; the wire outlet socket 8 can be provided to allow the lead wire 3 to be oriented to move to a position between the friction wheel assembly 10 and the synchronous belt assembly 11 when the lead wire 3 is inserted into the housing 1; further, as Figure 2As shown, in order to allow the lead wire 3 to be directed out of the housing 1, a guide hollow tube 9 connected to the outlet tube seat 8 is installed on the outlet 7 in this embodiment;
