[0036] In actual operation, when the device is used, when the filament needs to be bent, the device needs to be installed on the top of the workbench in advance, and the bolt 28 is counterclockwise rotated. When the bolt 28 is rotated, the internal space of the buckle 23 is increased. After increasing, the internal socket of the buckle 23 is clamped with the edge of the workbench, and then the bolt 28 is clockwise rotated. When the bolt 28 is clockwise rotated, the rubber boss 27 is rotatably installed between the top, so that the rubber boss 27 is contacted with the bottom of the workbench, so that the device is fixed. Thus, the device can be fixed at different positions.

[0037] When the fixing is completed, the processing shell 1 is manually rotated.

The trapezoidal push block 313 is contacted with the filament, so that the filament is pushed into the bending block 322 by the trapezoidal push block 313, so that the bending is completed. Thus, in the bending process, the filament is rollingly installed between the roller 326 and the roller shaft 321, so that the edges are not worn during the bending process, so that the filament is worn outside during the bending process, which causes poor bending quality.

[0039] It is to be noted that, as used in this specification and the appended claims, the singular forms "a," "an," and "the" include plural referents unless the context clearly dictates otherwise.
