Embodiment

The utility model is described in further detail below in conjunction with the drawings and specific embodiments:

Flat translation experimental demonstration instrument such as Fig. 1, the Fig. 2, shown in Figure 3 of throwing of the utility model, comprising: horizontal base 9 is equipped with 3 horizontal adjustment knob 10 on the horizontal base 9.

Vertical fixing has a supporting plate 3 on the horizontal base 9, vertically designs the adjustment hole 7 that a strip is arranged on the plate body of supporting plate 3.The top of supporting plate 3 is connected with the flat guide rail 6 of throwing, the flat guide rail 6 of throwing is divided into the inclined guide rails of left half and the horizontal guide rail of right half, flat bottom of throwing guide rail 6 has the base, design has mounting hole on the base, be connected with geometrical clamp 5 below the flat throwing guide rail 6, design has mounting hole, clamping screw 4 to pass geometrical clamp 5 on the geometrical clamp 5, flat base and the adjustment hole 7 of throwing guide rail 6 will be put down the top (referring to Fig. 2) that throwing guide rail 6 is locked at supporting plate 3.

The bottom of supporting plate 3 is connected with bottom guide track 8, bottom guide track 8 is divided into the inclined guide rails of left half and the horizontal guide rail of right half, the horizontal guide rail length of bottom guide track 8 right halfs is greater than the flat horizontal guide rail of throwing guide rail 6 right halfs, the bottom of bottom guide track 8 left half inclined guide rails has the base, design has mounting hole on the base, be connected with geometrical clamp below the bottom guide track 8 left half inclined guide rails, design has mounting hole on the geometrical clamp, clamping screw passes geometrical clamp, the base of bottom guide track 8 left half inclined guide rails and adjustment hole are locked at bottom guide track 8 bottom of supporting plate 3, base (referring to Fig. 4) can be with in the bottom of the horizontal guide rail of bottom guide track 8 right halfs, is located immediately on the surface level of horizontal base 9.
