Claim 1:
2. A tourniquet which comprises
a fixed module including a belt plate and a connecting belt;
wherein the belt plate comprises a through hole, and a protrusion formed by extending upward from a circumferential side of the through hole and retracting inward at a top end to form an annular opening, wherein both ends of the belt plate are respectively connected to both ends of the connecting belt which has an adjustable length;

a hemostatic module including a knob, a pressure stud and a hemostatic pad;
wherein the knob is wrapped around the protrusion and rotatable relative to the protrusion, and the knob is provided with a time device for recording the duration of hemostasis; the pressure stud is provided with an external thread, and the lower end of the pressure stud is fixedly connected with the hemostatic pad;
wherein the pressure stud moves downward by rotating the knob to drive the hemostatic pad to press down; and

an indicating module including a floating nut, a spinning press block, a spring, a connecting piece, a pointer and a dial;
wherein the upper end of the floating nut is fixedly connected with the top cover of the knob, and the floating nut is provided with internal threads, wherein the floating nut penetrates the protrusion and penetrates into an inner cavity of the protrusion, and the lower end of the floating nut is provided with a supporting part; wherein the pressure stud is arranged in the inner cavity of the floating nut, and is threadedly connected with the internal thread of the floating nut, wherein rotation of the knob drives the floating nut to rotate, so that the pressure stud threadedly connected with the floating nut moves downward;
the spinning press block is arranged around the floating nut, with an inner side of the spinning press block abutting against the floating nut, an outer side of the spinning press block being in thread-fit connection with an inner side of the protrusion, and the lower end of the spinning press block being supported by the support part; the spinning press block is provided with a holding hole penetrating through from top to bottom;
the spring is sheathed outside the floating nut, with the upper end of the spring abutting against a top inner surface of the protrusion, and the lower end thereof abutting against the upper end of the spinning press block;
the connecting piece is disposed in the holding hole, the connecting piece does not rise along with the spinning press block, but rotates along with the spinning press block, and the lower end of the connecting piece is fixedly connected to the pointer;
the pointer is arranged horizontally, and one end of the pointer is fixedly connected to the connecting piece and rotates with the connecting piece, and the other end of the pointer points to different pressure values on the dial.
