  The present invention provides a stand with a winding load receiving base that can move up and down, and the winding load receiving base is provided with a front winding support that supports both sides of the front end of the bow-like winding kite, and a rear winding support that supports both sides of the rear end. Provided is an arcuate curl support device provided with an operation device for moving a load receiving table up and down.

  The front and rear curl receptacles of the bow-shaped curl support device, at least the rear curl catch, have a height changing mechanism.

  Moreover, a sawdust tray that collects the sawdust generated by the injection of an arrow is provided on the wound support stand of the arched curl support device.

  The present invention uses a single arched curl support device to move the curl load cradle up and down by the vertical motion operating means, so that the curl can be appropriately adjusted to a height corresponding to the height of various archers, You can practice effectively.

  Further, it is possible to stably support the front and rear reel holders regardless of the diameter of the reel.

  Moreover, it has the same support function as several kinds of roll support bases with one bow-type roll support device, it can reduce cost, reduce the storage space, lower the roll load receiving base and load the rolls. Since it can be lifted up to a predetermined height, it reduces the labor and labor of replacing the roll.

  Further, the waste generated when the arrow is shot can be effectively collected by the waste catcher, and the saucer can be moved up and down together with the winding load receiving base to always maintain an appropriate waste collection position.

  Further, the opposite angle of the front end surface (arched surface) of the winding rod can be set to a vertical or oblique angle by changing the height of at least the latter winding rod receiver.
