The invention discloses a mechanical full-range pointer type liquid level device comprising an instrument box (1), an instrument pointer (2), an instrument panel (3), a magnetic steel assembly (4), an O-shaped ring (5), a sealing block (6), a rotary fixing table (7), a spiral plug pin (8), a floating block (9), a spiral rod (10), a rotary shaft sleeve (11), a rotary shaft (12), a gear box (13), a spiral rod gear (14), a rotary shaft gear (15), a circular through hole A (16), a rectangular through hole B (17) and a stainless steel rotary block (18). Buoyancy generated by up-and-down change of the liquid level surface is used as a power source, and the up-and-down positions of the floating block on the screw rod are changed to realize rotation of the screw rod, so that the gear at the lower end of the screw rod is driven, and power is transmitted to the rotating shaft to drive the magnetic steel and the pointer at the top end of the rotating shaft. Therefore, the function of liquid level reading is realized. Th
