[0028] like Figure 5 , Figure 7 As shown, in order to facilitate the limiting of the contact limiting shaft 5, a pressure cap 51 is rotatably connected to the top of the shaft head 50.

[0029] like Figure 2 , Figure 5 , Figure 6 As shown, in order to reduce the friction force when the compression belt 3 is rolled up, a round roller 21 and a pressure plate 22 are provided between the side plates 20. The round roller 21 is rotatably connected to the side plates 20. There are two groups of round rollers 21 and they are symmetrically arranged on both sides of the pressure plate 22. The positions of the pressure plate 22 and the round rollers 21 match, and the compression belt 3 passes through the gap between the round rollers 21 and the pressure plate 22.

[0030] like Figure 5 As shown, in order to make the compression belt 3 fit with the tightening roller 4, a pressure rod 41 is symmetrically provided on the tightening roller 4. The pressure rod 41 is parallel to the axial direction of the tightening roller 4, and the compression belt 3 passes between the tightening roller 4 and the pressure rod 41.

[0031] like Figure 1 As shown, in order to prevent the belt 1 from slipping and loosening, an anti-sliding block 12 is provided on the outer side of the buckle 11 , and the anti-sliding block 12 matches the size of the belt 1 .

[0032] like Figure 8 , Fig. 9 As shown, in order to enhance the compression hemostasis effect, a block 1 33 is provided on the inner side of the easily detachable buckle 31, and a socket 35 is provided on the block 1 33; a block 2 34 is provided on the inner side of the easily detachable plug 32, and an insert block 36 is provided on the block 2 34; both the block 1 33 and the block 2 34 are semi-arc blocks, and the sizes of the block 1 33 and the block 2 34 match and correspond to each other, and the sizes of the insert block 36 and the socket 35 match and correspond to each other.

[0033] The working principle of the utility model is as follows: first, the waist belt 1 is worn on the patient's waist, the two ends of the waist belt 1 are separated, and then the waist belt 1 is passed around the patient's two sides, and then the end of the waist belt 1 with the block Velcro 13 is passed through the buckle 11, and then the waist belt 1 is wound back backwards to make the waist belt 1 contact with the anti-sliding block 12, and the length of the backward winding is adjusted to make the waist belt 1 fit the patient's waist, and then the block Velcro 13 is fitted with the belt Velcro 14 to make the waist belt 1 firmly worn on the patient, and then the compression belt 3 is worn, and the easy-to-detach buckle 31 and the easy-to-detach plug 32 are first separated, and the compression belt 3 is driven to go around the two sides of the patient's thighs, and then Then, the easily detachable buckle 31 and the easily detachable plug 32 are buckled together, so that the compression belt 3 is wrapped around the patient's thigh, and the plug block 36 is inserted into the socket 35, so that the group block 1 33 and the group block 2 34 are combined into a compression block, and the compression block is placed on the hemostasis point for compression. During this process, the compression block drives the compression belt 3 to move, and the compression belt 3 slides on the tightening roller 4, and then the handle 54 is rotated to drive the limit shaft 5 and the tightening roller 4 to rotate, and the pressure rod 41 presses the compression belt 3 on the tightening roller 4, and the compression belt 3 is wound around it as the tightening roller 4 rotates. During this process, the limit seat 52 rotates with the handle 54, and the limit seat 52 and the sleeve 23 are spaced apart. The ratchet surfaces rotate alternately until the compression belt 3 is completely tightened. At this time, due to the pressure of the spring on the shaft head 50, the limit shaft 5 is automatically lifted up, driving the limit seat 52 to be close to the lower sleeve 23, and the ratchet surfaces bite each other, so that the limit seat 52 cannot rotate in the opposite direction, so that the tightening roller 4 plays a tightening role. In this process, the side plate 20 provides support for the tightening roller 4, the pressure plate 22 contacts the surface of the patient's limbs, improving the comfort of use, and the round roller 21 reduces the friction of the movement of the compression belt 3 and makes the contact surface of the compression belt 3 flush with the patient's limbs, which is convenient for tightening or loosening. Since the connecting belt 10 connects the belt 1 It is connected with the tightening seat 2 to maintain the wearing position of the compression belt 3 and prevent the compression belt 3 from loosening and slipping. After the compression is completed, when the compression belt 3 needs to be loosened, the pressure cap 51 can be pressed to drive the limit shaft 5 to fall, and the synchronization block 53 on the limit shaft 5 slides in the tightening roller 4, and then the limit seat 52 is separated from the sleeve 23 on the lower side, and the two ratchet surfaces are separated, so that the limit seat 52 and the limit shaft 5 are out of the limit. At this time, the compression belt 3 can be pulled outward to a suitable length, and then the pressure cap 51 is loosened, the easy-to-remove buckle 31 and the easy-to-remove plug 32 are disassembled, and then the block-shaped Velcro 13 and the belt-shaped Velcro 14 are separated, and the belt 1 can be removed.
