The invention relates to the technical field of well lid opening tools, in particular to a multipurpose portable special tool for opening a well lid. The multipurpose portable special tool comprises a vertical crowbar and a cross crowbar. The vertical crowbar comprises an on-well segment and an under-well segment which are sequentially fixed together from top to bottom, and the thickness of the under-well segment is smaller than that of the on-well segment. The on-well segment is fixed with a horizontally-forward supporting rod, and the under-well segment is fixed with a check block with the thickness corresponding to that of the under-well segment. A sleeve ring which matches the supporting rod and can rotate around the supporting rod is fixed to the middle of the cross crowbar, and a supporting piece is fixedly arranged at the right end of the cross crowbar. The multipurpose portable special tool is reasonable and compact in structure and convenient to use. The check block is inserted into a hole of the well lid to rotate and then is clamped on the lower end face of the well lid, a user holds the left end of the cross crowbar to exert force upwards, and after the supporting piece moves downwards along with the right end of the cross crowbar and is abutted against the upper end face of the well lid, the user continues to exert force, and the well lid can be opened easily and safely. The supporting rod and the sleeve ring are combined, so that the cross crowbar and the vertical crowbar are easily separated to facilitate carrying.
