[0033] The wire storage barrel 2 is divided into a wire storage end and a wire receiving end.

The cross-section of the protrusion 606 is trapezoidal. The protrusion 606 is used to clamp and fix the metal wire 11, thereby improving the tightness between the metal wire 11 and the first clamping plate 604 and the second clamping plate 605.

[0037] At least one fixed rod 8 is connected to the auxiliary plate 5, a first telescopic rod 9 is installed on the fixed rod 8, a guide wheel 10 is installed on the first telescopic rod 9, at least one second telescopic rod 12 is connected to the auxiliary plate 5, a guide wheel 10 is installed on the second telescopic rod 12, and the first telescopic rod 9 and the second telescopic rod 12 are used to adjust the position of the guide wheel 10 to facilitate tightening the metal wire 11.
