 An embodiment of the present invention will be described below with reference to FIGS. In this embodiment, the same parts as those of the conventional example are designated by the same reference numerals, and detailed description thereof will be omitted. In this embodiment, the shooter 21 is composed of a fixed shooter portion 22 and a movable shooter portion 23, and the operator only has to rotate the movable shooter portion 23 when changing the shooter position. .. As shown in FIGS. 3 and 4, the fixed shooter portion 22 is formed by bending an iron plate into a U-shape so that the bottom plate portion 24 is rectangular and the side plate portions 25 are triangular gutters. The bottom plate portion 24 is protruded from the side plate portion 25 on the base end side (right side in FIG. 3) of the fixed shooter portion 22 and is bent in a V shape. Further, on the lower surface of the bottom plate portion 24, reinforcing plates 26, 26 which are arranged in parallel and spaced apart from each other are fixed in a so-called back-back reinforcing state. The upper end of the side plate portion 25 (on the left side in FIG. 3) is a cutout portion 27 that is cut out in a rectangular shape. Further, the upper edge of the side plate portion 25 is slightly folded back inward except for a small portion on the base end side and the front end side.

The fixed shooter portions 22 are provided on the inner sides of the upper frames 5 a, 5 a of the main body 5 which face each other. The base plate side end of the bottom plate 24 is narrowed and inserted into the vertical frame (not shown) of the fixed plate 6 and is mounted on the horizontal frame 5b installed on the upper frames 5a and 5a. It is placed and fixed. The vicinity of the notch 27 at the upper end on the tip side of the side plate portion 25 is attached to the angled horizontal frame 5e that is erected on the upper frames 5a, 5a via the attachment member 28 in a hanging shape. As shown in FIG. 2, the attachment member 28 is formed by bending both ends of the strip plate in a U shape (folded downward in FIG. 2) to form a side plate attachment portion 28a, and an intermediate portion of the strip plate is It is extended in the width direction and is bent to the opposite side (upper side in FIG. 2) to the bent side of the both ends to form a horizontal frame mounting portion 28b. The horizontal frame attachment portion 28b is attached to the horizontal frame 5e, and the side plate portion 25 of the shooter 21 is attached to the side plate portion attachment portion 28a.

The movable shooter portion 23 of the shooter 21 is U-shaped. The base end portion of the side plate portion 31 of the movable shooter portion 23 is formed into a round shape, and the base end portion of the side plate portion 31 is positioned outside the tip of the side plate portion 25 of the fixed shooter portion 22 and is provided with a shaft 32. It is rotatably attached. An elongated hole 33 is formed on the tip side of the side plate portions 31. Most of the upper edge of the side plate portion 31 is folded back inside the movable shooter portion 23. On the other hand, on the horizontal frame 5d connected to the lower frame 5c of the main body 5, a support stand 34 is provided upright outside the tip side of the movable shooter portion 23 of the shooter 21. The support base 34 is provided with bolts 35 at intervals in the lengthwise direction. The bolt 35 is inserted into the elongated hole 33 of the movable shooter portion 23, and the tip side portion of the side plate portion 31 of the movable shooter portion 23 is attached to the support base 34 via the bolt 35 and the nut 36 screwed to the bolt 35.
