In some embodiments, a section of the pull rod 52 extending into the counterbore of the tension bolt 54 is sleeved with a spring B531, and the spiral ring 53 presses the spring B531 towards the bottom wall of the counterbore of the tension bolt 54. By adjusting the position of the spiral ring 53 relative to the pull rod 52, the initial compression amount of the spring B531 can be adjusted, and the pressure floating interval of the compression band 4 to the wound site can be adjusted.

The pressing mechanism is arranged on the right side wall plate of the rack 2 and is oppositely arranged below the tension mechanism. The pressing mechanism comprises a driving part and a blocking part, the driving part is arranged on a right side wall plate of the rack, and the blocking part is arranged at one end, facing the compression belt, of the driving part. The driving portion can push the blocking portion to move towards the direction of the compression belt. The end face of one end, opposite to the compression belt, of the blocking part is concave inwards to form an arc shape. The pressing means are arranged to contact the outer side of the thigh and to exert an inwardly directed blocking force on the outer side of the thigh, while cooperating with the pressing belt 4 to fix the device according to the solution of the invention relative to the thigh.
