Coupling method of multi-parameter sensor

The invention discloses a multi-parameter sensor which comprises a pointed cone fixing seat, a connecting rod mechanism base is arranged at the bottom of one end in the pointed cone fixing seat, a movable block is slidably connected in the connecting rod mechanism base, a core sensor is arranged at one end, away from the connecting rod mechanism base, in the pointed cone fixing seat, and a push rod is inserted in the movable block in a penetrating mode. A cable is arranged in the pushing rod and fixedly connected to the core sensor, a waterproof connector is arranged at the joint of the cable and the core sensor, a connecting rod support is rotationally connected to the top of the end, close to the waterproof connector, of the pushing rod, and a connecting rod is rotationally connected between the connecting rod support and the outer top of the pointed cone fixing base. Compared with the prior art, the device has the advantages that reliable coupling receiving of seismoelectric and electric field signals is r
