Therefore, when the strap K wrapped around the bundled object E is placed on the side of the base of the strap device 60 and is located below the pulley 603, the strap guide plate 607 with elastic force can automatically position the screw 6071 Because the axis point is directly pushed and swung by the strap K, the driving operation of the strap K by the pulling pulley 603 is not hindered at all. On the contrary, please refer to Fig. 10 and Fig. 11 again, when the pulley motor 608 is pulled up and the pulley 603 with its upper swing does not engage with the corresponding anti-slip block 605, and the strap K has not been placed yet. When the belt pulley 603 is below the belt pulley 603, since the belt guide plate 607 has the force of springing in the direction of the pulley pulley 603 at any time, it is not pushed in by the strap K and the pulley pulley 603 and the side seat 604 of the gearbox In the case of upward swing, it is inevitable that it will automatically spring and swing in the direction of the pulley 603 and just stop at the outer cover 6041 of the gearbox side seat 604, so that the coaxial with the gearbox side seat 604 The pulling pulley 603 cannot swing down together, and further, the pulling pulley 603 can be used to constantly not engage with the corresponding anti-sliding block 605, so that the first switch 901 of the air pressure control valve 90 is accidentally touched by mistake and the pulling pulley can be caused. When the motor 608 is driven, the pulling pulley 603 and the anti-slip block 605 will not be damaged by mutual direct friction at all. the

Of course, since the lower end of the belt guide plate 607 is provided with a transverse arc-shaped groove 6073, the user can also lock it with the screw 6074 so that the most appropriate position can be kept without swinging. the
