DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0028] Please refer to Figures 1-4 The skin tension-reducing patch comprises a first base cloth 1 and a second base cloth 2. The first base cloth 1 is fixed with a stay 4. The end of the stay 4 and the first base cloth 1 are adhered with a base plate 3. The second base cloth 2 is fixed with a rack box 5. The second base cloth 2 and the rack box 5 are also adhered with the base plate 3. The stay 4 is pulled out of the rack box 5.

[0029] The limit tooth 6 is elastically connected in the rack box 5. The limit tooth 6 is engaged with the tooth groove on the side of the stay 4.

[0030] The release mechanism 7 is further arranged on the rack box 5 and connected with the limit tooth 6. When the ends of the stay 4 on the first base cloth 1 and the release mechanism 7 are respectively hooked by two fingers of a doctor and the two fingers are forced to approach each other, the limit tooth 6 is first pulled by the release mechanism 7 to move and release the engagement with the stay 4. Then the stay 4 can be smoothly pulled in the rack box 5 without obstruction to control the closure of the wound.

[0031] After the wound is closed, the release mechanism 7 is released. The limit tooth 6 can be reset to engage with the tooth groove on the corresponding position of the stay 4 to maintain the closed state of the wound.

[0032] Please refer to Figures 4-5 The limit tooth 6 is a triangular tooth. The tooth is rotatably connected with the rack box 5 through the shaft 64 at the angle 61 away from the stay 4. The shaft 64 has a rotary elastic force. Alternatively, the shaft 64 is a hard rod. The hard rod is rotatably connected with the rack box 5. The elastic member is connected between the side of the limit tooth 6 and the rack box 5.

[0033] The second angle 62 of the limiting tooth 6 is close to the stay 4 and is inserted into the tooth groove to engage with the stay 4, the third angle 63 is connected with the release mechanism 7, the third angle 63 is close to the first base cloth 1 relative to the second angle 62, and the release mechanism 7 is pulled to drive the limiting tooth 6 to rotate outward around the shaft 64, that is, to rotate away from the first base cloth 1, so that the second angle 62 just disengages from the tooth groove and rotates to a position close to the side edge of the stay 4;

[0034] When the release mechanism 7 is pulled towards the first base cloth 1, the limiting tooth 6 is pushed to rotate away from the first base cloth 1, and after the force on the release mechanism 7 disappears, the limiting tooth 6 is rotated back and quickly re-engages with the stay 4 to lock the position of the stay 4 by the rotation elastic force of the shaft 64 or the rebound of the elastic member.

[0035] Please refer to Figure 2 and Figure 5 , the skin tension-reducing patch, the release mechanism 7 includes a sliding plate 71 and a force applying handle 72 fixed on the sliding plate 71, the top of the rack box 5 is provided with a channel groove 51 for sliding of the sliding plate 71, the sliding plate 71 is provided with an inclined groove 712, the end of the inclined groove 712 away from the stay 4 is close to the first base cloth 1, the end close to the stay 4 is away from the first base cloth 1, a convex shaft 73 fixed on the third angle 63 of the limiting tooth 6 is inserted into the inclined groove 712, and when the force applying handle 72 is pushed towards the first base cloth 1, the convex shaft 73 is driven to slide in the inclined groove 712, at the same time, the limiting tooth 6 is rotated from the position away from the stay 4 to the position close to the stay 4, so that the second angle 62 moves outward to release the engagement state with the stay 4;

[0036] The limiting tooth 6 is symmetrically distributed relative to the two sides of the stay 4 in the stay 4 box, and the sliding plate 71 is provided with two groups of inclined grooves 712 corresponding to the two groups of limiting teeth 6, and the movement of the sliding plate 71 controls the two groups of limiting teeth 6 to be engaged with or disengaged from the stay 4 synchronously;

[0037] The rack box 5 is provided with a recess 52 for rotation of the limiting tooth 6, the recess 52 is communicated with the hole for the stay 4 to pass through, when the second angle 62 engages with the stay 4, the edge between the first angle 61 and the third angle 63 contacts with the wall of the recess 52 to block the stay 4 from retreating;

[0038] As a preferred, the force applying handle 72 is detachably connected with the sliding plate 71 through the convex 721 fixed at the bottom end inserted into the insertion hole 711 provided on the sliding plate 71, which facilitates finger force and also enables the force applying handle 72 to be pulled out after the tension-reducing patch is well attached, and after the force applying handle 72 as the force receiving end is lost, the sliding plate 71 is hidden in the channel groove 51 and is difficult to be misoperated, thereby improving safety.

[0039] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
