Abstract: A drawer panel adjusting device includes a fixed member, a first movable member, a first adjusting member, a second movable member, and a second adjusting member. The first adjusting member is located between the fixed member and the first movable member. A spiral block on the first adjusting member extends through a gap between two limiting blocks on the fixed member. The second movable member is mounted in an assembling groove of the first movable member. The second movable member includes a second adjusting hole and a guiding block located in the second adjusting hole. The second adjusting member includes an outer periphery having a spiral guiding groove. The second adjusting member extends through the second adjusting hole and is restrained in the assembling groove. The guiding block is engaged in the spiral guiding groove.

Abstract: A drawer adjusting device includes a fixed member having an adjusting hole. A movable member includes two limiting blocks spaced from each other by a gap. The movable member includes an upper pushing portion on a top end thereof and a lower pushing portion on a bottom end thereof. An adjusting member includes a first side having a control portion and a second side having a spiral block. A spacing between the spiral block and a central axis of the adjusting member gradually increases from an end of the spiral block toward another end of the spiral block. The adjusting member is located between the fixed member and the movable member. The control portion is received in the adjusting hole. The spiral block extends through the gap between the two limiting blocks.
