摘要： Disclosed is a tourniquet, comprising a fixing module, a hemostasis module, and an indication module. A floating nut is arranged around a pressure stud, with the upper end of the floating nut being fixedly connected to a rotary knob, and the lower end of the floating nut being provided with a support part; 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 a 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 the top face 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; and the pointer rotates along with the connecting piece to point to different pressure values on the dial plate; a time device can also be provided to measure the hemostasis time; the tourniquet can be locked. The present invention is simple in terms of structure and easy to process, easier to observation of the value of applied pressure, highly precise, convenient timekeeping, and safer.
