[0124] Both ends of the opening 7 on the upper part of the support rail 2 are closed and fixed to prevent the pressing portion 4 of the self-locking structure from slipping off from both sides of the opening 7 of the support rail 2 when moving;

[0125] The inner side of the upper part of the support rail 2 is additionally provided with a slide rail 9 which is horizontal to the support rail, and a freely slidable slider 10 is provided in the slide rail 9;

[0126] The outer side of the locking bar 3 and the slider 10 provided in the slide rail 9 on the inner side of the upper part of the support track 2 are also connected and fixed by a spring 11. When no external force is applied, the spring 11 is in a contracted state, so that the self-locking row of teeth 5 on the locking bar 3 engages and locks with the track row of teeth 8 on the inner side of the upper part of the support track 2;

[0127] The patch 1 is in the shape of a long strip, and is provided in groups of two. One side of the patch 1 is sticky and can be bonded to the skin, and the other side is bonded to the bottom of the support track 2 and / or the fixed base 6 that can be self-locked.

[0128] The two support rails 2 are respectively bonded to the symmetrical positions of the two patches 1 .

[0129] The patch 1 is provided with tear lines 12 evenly or unevenly parallel to the short sides; the support track 2 is bonded and provided in the center area of ​​the patch between every two adjacent tear lines 12;

[0130] The bidirectional adjustable tension-reducing device with a detachable dressing also includes a detachable dressing; the detachable dressing includes one or more detachable dressing units 13 with regular or irregular shapes and a dressing hook 14; the detachable dressing composed of one or more dressing units 13 can adapt to the shape of the wound surface;

[0131] The dressing hook 14 is bent into a hook shape;

[0132] The dressing unit 13 can be in different shapes such as a strip, a circle, a polygon, etc.;

[0133] The dressing unit 13 is provided with one or more holes, and the dressing hook can be hung on the holes of different dressing units;

[0134] A plurality of dressing units 13 are connected to each other through dressing hooks 14 and holes on the dressing units to form the detachable dressing;

[0135] When the detachable dressing is used, one or more dressing units in the entire structure can be added, discarded, or replaced to make it more in line with the needs of actual conditions.

[0136] In actual use, when the two-way adjustable tension-reducing device does not need to be adjusted, the locking bar 3 fixedly connected with the pressing parts 4 at both ends are naturally loosened, and under the action of the spring 11, the locking bar 3 itself is pulled toward the inner side of the upper part of the support rail 2, and the self-locking teeth 5 are engaged and locked with the rail teeth 8, and the self-locking structure cannot move in the support rail 2.

[0137] When it is necessary to adjust the length of the lock bar between the two support rails 2 in the tension-reducing device, the pressing part 4 in the self-locking structure is pressed, the spring 11 is extended under the action of the force, the self-locking row of teeth 5 is disengaged from the track row of teeth 8, and the lock is released, so that the self-locking structure can move freely in the support rail 2. When it moves to the predetermined position, the pressing part 4 pressed by hand is released, and the lock bar 3 of the self-locking structure itself is pulled toward the inner side of the upper part of the support rail 2 under the action of the elastic force, and the self-locking row of teeth 5 and the track row of teeth 8 are re-engaged and locked;

[0138] In actual use, a removable dressing may be placed between the two support rails 2 and between the locking strip 3 and the skin.

[0139] The protection content of the present invention is not limited to the above embodiments. Without departing from the spirit and scope of the utility model concept, changes and advantages that can be thought of by those skilled in the art are included in the present invention and are protected by the attached claims.
