[0006] Preferably, a groove is formed in the middle of the support table, the fixing mechanism comprises clamping jaws arranged in the groove and rotatably arranged, the clamping jaws are arranged in pairs and oppositely, a conical block is arranged at the lower end of the fixed shaft, and the two clamping jaws clamp the surface of the conical block.

[0007] Preferably, a rotating shaft is arranged through the clamping jaw, the rotating shaft is fixedly connected to the support table, and a torsional spring is arranged between the clamping jaw and the rotating shaft.

[0008] Preferably, an arc-shaped through slot is further arranged on the side surface of the support table, the arc-shaped through slot is communicated with the groove, a lever is arranged in the arc-shaped through slot, one end of the lever is fixedly connected to the lower end of the clamping jaw, and the other end of the lever penetrates out of the arc-shaped through slot.

[0009] Preferably, a limiting guide disc is arranged below the pressure plate, and the limiting guide disc is circular.

[0010] Preferably, the edge of the wire drum is arc-shaped.

[0011] Preferably, the guiding buffer is a plastic filament segment.

[0012] Beneficial effects: By the technical scheme, the wire drum is vertically placed, so that the wire drum does not need to be driven to rotate by a driving motor during wire feeding, thereby reducing energy consumption. The wire feeding of the technical scheme is to pull the wire in the subsequent process, thereby achieving the effect of front-end wire feeding. The circular limiting guide disc and the arc-shaped edge of the wire drum are both used to avoid abrasion of the wire harness, and the pressing disc is made of ceramic material to be smoother and have no abrasion. The fixed shaft is used to limit the pressing disc above the wire drum, so that the pressing disc is stable during wire feeding, which is beneficial to better guiding of the wire. When disassembly is needed, the fixed shaft is pressed downward, and when the lower conical block passes through the two clamps, the clamps can limit the conical block. When the conical block needs to be taken out, the clamping jaw is rotated by moving the lever, so that the conical block is separated from the two clamps. In the loosened state, the technician can take out the fixed shaft upward between the two clamps, so that the pressing disc can be taken out, thereby achieving the purpose of conveniently replacing the wire drum.
