The present invention provides a swing plate device capable of realizing a trouble shot wherein the swing plate device is installed as a pair of left and right foot devices to be separable and to have the same structure such that the swing plate device is useful in an actual exercise of a trouble shot, even when the invention is used for a long time, it is possible to make a stable up and down movement, possible to make a slope inclined up and down and left and right and possible to secure a sufficient up and down movement space in a limited space. Each of the left and right foot devices comprises: a pair of a support plate and a bottom plate positioned spacing apart at a predetermined interval; a pair of upper fixing plates installed to both sides of a lower surface of the support plate and having a long hole; a pair of lower fixing plates installed to both sides of an upper surface of the bottom plate and having a long hole; a pair of cross links installed between the upper and the lower fixing plate and having a X shape and having one end portion coupled to the long hole to be able to slide and having the other end portion fixedly coupled to either the upper fixing plate or the lower fixing plate to be able to rotate; a cylindrical body connected to one end portion of the cross link coupled to the long hole of the lower fixing plate and having a female screw formed on an inner surface; a screw rod having a male screw, which is coupled to the female screw of the cylindrical body, formed on an outer circumferential surface; a motor fixedly installed to the bottom plate and for generating a rotational force; and a power transmission device for transmitting the rotational force of the motor to the screw rod. |
