A magnetic sensor includes a casing body having opposite first and second ends, a receiving notch proximate to the second end, and a through hole communicating with the receiving notch. A positioning unit includes a bushing disposed in the receiving notch and having a protrusion, and an adjustment member having a rotary portion retained rotatably in the through hole, and a head portion fixed to the tubular portion. The bushing is rotatable relative to the casing body between protruded and retracted positions, where the protrusion is protruded out of and retracted into the receiving notch so that the bushing interlocks and uninterlocks with blocking portions of a pressure cylinder, respectively. A sensing module is disposed in the casing body in proximity to the first end. |
