Patch with expansion support effect

A patch with an expansion support effect comprising a body, at least one first supporting element, and at least one second supporting element, the at least one first supporting element and the at least one second supporting element disposed on the body, and the at least one second supporting element being mutually active and set up with the at least one first supporting element;

• wherein the body is an elongated sheet and has a length, two opposite ends, a bottom face, a top face, an adhesive surface, and a mounting surface, the adhesive surface and the mounting surface are respectively disposed on the bottom face and the top face of the body along a lengthwise direction of the body;
• wherein the at least one first supporting element is disposed on the body along the lengthwise direction of the body and has a fixed segment, an engaging segment, and a movable segment, the fixed segment is disposed on the mounting surface of the body at one of the two opposite ends of the body along the lengthwise direction of the body, the engaging segment is connected to the fixed segment, and the movable segment is disposed on the mounting surface of the body away from the fixed segment;
• wherein the at least one second supporting element is disposed on the body along the lengthwise direction of the body, aligns with the at least one first supporting element, and has a fixed segment disposed on the mounting surface of the body at the other one of the two opposite ends of the body along the lengthwise direction of the body, an engaging segment connected to the fixed segment of the at least one second supporting element, and a movable segment disposed on the mounting surface of the body away from the fixed segment of the at least one second supporting element;
• and
• the engaging segment of each one of the at least one first supporting element and the at least one second supporting element engages with the movable segment of the other one of the at least one first supporting element and the at least one second supporting element;
• wherein the engaging segment of the at least one first supporting element has multiple engaging units;
• the movable segment of the at least one second supporting element has at least one stuck unit;
• and the at least one stuck unit of the movable segment of the at least one second supporting element engages with the engaging units of the engaging segment of the at least one first supporting element;
• wherein each engaging unit of each one of the at least one first supporting element and the at least one second supporting element is a one-way engaging tooth;
• the at least one stuck unit of each one of the at least one first supporting element and the at least one second supporting element is an engaging hole formed through the respective movable segment;
• and an engagement between the one-way engaging tooth and the engaging hole of the at least one first supporting element and the at least one second supporting element allows adjusting a distance between the at least one first supporting element and the at least one second supporting element;
• wherein the engaging segment of each one of the at least one first supporting element and the at least one second supporting element is a belt extending along the lengthwise direction of the body;
• and the movable segment of each one of the at least one first supporting element and the at least one second supporting element is securely disposed on an end of the engaging segment of the respective supporting element away from the fixed segment of the respective supporting element and is disposed above the mounting surface of the body and wherein each one of the at least one first supporting element and the at least one second supporting element has multiple supporting segments securely disposed on the mounting surface of the body at spaced intervals between the fixed segment and the movable segment of the respective supporting element;
• and each supporting segment of each one of the at least one first supporting element and the at least one second supporting element is movably connected to the engaging segment of the respective supporting element to hold the engaging segment of the respective supporting element steadily disposed above the mounting surface of the body.
