[0002] During mechanical operations, screws and other components are often found in corners, blind spots, and confined spaces, making them difficult to remove and install. These can even require damaging the outer casing or insulation. For some non-complete equipment, specialized tools are often lacking to remove or install components, such as pulleys on shelves or flatbed trucks. Limited operating space necessitates carrying multiple tools.

[0003] The invention discloses a deformable wrench with authorization announcement number CN213858982U, comprising an upper wrench, a lower wrench, and an extended handle. The upper surface of the lower wrench is embedded with a slot, and the lower surface of the upper wrench is provided with an insert that matches the slot, so that the upper and lower wrenches can be connected in an interlocking manner.

One end of the extended handle is provided with a connecting end that matches the fixed end, and the connecting end is provided with a fixing block that can be inserted into the fixing slot. The fixed end and the connecting end are fixedly connected by a pin. The other end of the extended handle is embedded with a screwdriver with a detachable pin.
