Adjustable heating type electrocardiogram lead electrode clamp

The utility model provides an adjustable heating type electrocardiogram lead electrode clamp which is novel in structural design. Comprising a cross rod, a sliding groove is formed in the center of the outer wall of the bottom of the cross rod, a lead screw is movably connected to the axis of the sliding groove through a bearing, a sliding block slidably connected into the sliding groove is in threaded connection to the outer side wall of the lead screw, and positioning grooves are formed in the centers of the inner walls of the two sides of the sliding groove; and positioning plates slidably connected into the positioning grooves are welded to the outer walls of the two sides, close to the positioning grooves, of the sliding blocks correspondingly, and a motor is installed at one end of the transverse rod through a screw. The motor drives the lead screw to rotate, the lead screw drives the sliding block in threaded connection with the lead screw to slide along the sliding groove, the sliding block drives the
