Meanwhile, since the screw rod I415 is only inserted into the mounting hole I423, the screw rod I415 can rotate relative to the mounting plate 406, so that when the abutting wheel 401 is connected with the screw rod I415 and the abutting wheel 401 is influenced by the driving belt 5 to rotate, the mounting plate 406 does not form constraint on the screw rod I415 to prevent the screw rod I415 from rotating.

firstly, the position of the tension wheel 3 is adjusted so that the transmission belt 5 can be driven by the driving wheel 2, and at the moment, the transmission belt 5 is automatically pressed to be abutted with the supporting component due to the tension spring 411 of the abutting wheel 401;

then, during actual machining, when the mounting plate 406 is forced to rotate around the pivot rod 402 due to stroke interference between the belt 5 and the support assembly, the tension spring 411 is extended and the compression spring 413 is compressed;

finally, the tension spring 411 and the compression spring 413 return by their nature, at which point the tension spring 411 and the compression spring 413 pull the mounting plate 406 so that the abutment wheel 401 presses the belt 5 against the support assembly from a new one.
