Protective relay with easy withdrawal

A protective relay comprising:

• an inner casing including:
• a back casing having a receiving space defined therein for accommodating a component therein;
• a front casing having a display and a plurality of buttons, wherein the front casing is coupled to the back casing;
• a front frame disposed along an edge of the inner casing;
• a handle having a lever structure, wherein the handle is pivotably coupled to the front casing, defines a portion of the front frame, and has a 90 degrees-pivoted U shape, wherein both ends thereof are pivotably coupled to the front casing;
• and
• a pair of pivotable frames respectively coupled to an inner side of the handle so as to face each other;
• and
• an outer casing constructed for detachably receiving the inner casing therein, wherein the outer casing includes a pair of support brackets respectively mounted on both opposite sides of an open end of the outer casing for detachably supporting the handle, wherein each of the support brackets includes a handle support protruding toward the inner casing,
• wherein when the inner casing is separated from the outer casing, the handle pivots at a state where a portion thereof is in contact with the support brackets, thereby pushing the inner casing out of the outer casing,
• wherein each of the pivotable frames has a distal end having a V shaped portion, wherein the distal end is pivotably coupled to the handle support,
• wherein each of the pivotable frames has a pivoting point at the distal end, and
• wherein when the pivotable frames are pivoted around the pivoting point together with a pivoting of the handle, the distal end of the pivotable frames is inserted or separated into or from the support brackets.
