The two adjustment nuts 24 are respectively threadedly connected to the outsides of the two threaded rods 21. When compressing hemostasis, the connection height can be changed by turning the adjustment nuts 24 along the outsides of the threaded rods 21. The elastic force of the first spring 23 pushes the adjustment plate 22 to abut against the adjustment nuts 24. The distance between the adjustment plate 22 and the hemostatic base 1 can be quickly changed to adapt to the patient's limbs for better hemostasis.

During surgical hemostasis, the hemostasis base 1 is placed at the hemostasis site, and the limb is placed in the placement groove 25 to cooperate with the buffer pad 26 to position the limb. At the same time, when compressing hemostasis, the connection height can be changed by turning the adjustment nut 24 along the outer side of the threaded rod 21.
