Abstract: A front connecting device of a concealed slide includes a metal base, an elastic fastener, a level adjusting member and a vertical adjusting member. The metal base is mounted to a drawer, and the elastic fastener, the level adjusting member and the vertical adjusting member are movably installed to the metal base, and the elastic fastener is connected to an end of the concealed slide for adjusting a horizontal position and/or a vertical position of the concealed slide. The elastic fastener is integrally formed by plastic injection and includes a fastening portion, a handle, and an elastic portion disposed between the elastic fastener and the fastening portion. The handle may be pressed to deform the elastic portion and separate the fastening portion from the concealed slide. The device not only provides a convenient operation, but also lowers the manufacturing cost while maintaining the original functions.

Abstract: A concealed slide module is formed by installing an inner plate, at least one first ball plate, a middle plate, at least one second ball plate and an outer plate sequentially and installed between a bottom side of a drawer and a cupboard. The middle plate covers the exterior of the first ball plate and has an inner sidewall facing the inner plate and having a roof portion protruded horizontally outward from the top side of the middle plate, and a sliding section bent inwardly from a lower edge of the sidewall, and the sliding section is parallel to the platform, and a guide wheel is protruded from an outer sidewall at an end of the middle plate, and the middle plate slides with respect to the inner plate through the first ball plate.
