The first elastic frame grooves 361 provided on the outer circumferential portion of the first B coupling member 320 and the outer circumferential portion of the second B coupling member 340 are formed such that the coupling portion 300 is expanded to generate an elastic force on the elastic frame 200 The elastic frame 200 is a groove in which the elastic frame 200 is seated. Since the first and second B-joining members 320 and 340 are disposed to face the envelope 100, when the coupling portion 300 is expanded and an elastic force is generated, And is folded toward the frame groove 361 to be seated in the first elastic frame groove 361. The elastic frame 200 seated in the first elastic frame groove 361 is elastically deformed by applying a resilient force to predetermined portions of the envelope 100 by the positions fixed and defined by the first elastic frame grooves 361 do.

The second A elastic frame grooves 362 and the second B elastic frame grooves 363 provided at the outer circumferential portion of the first A coupling member 310 and the outer circumferential portion of the second A coupling member 330 are formed such that the coupling portions 300 are folded, And is a groove in which the elastic frame 200 is seated when the elastic force is released from the frame 200.

The reason why the elastic frame 200 seated in the second A elastic frame grooves 362 allows clearance and rotation along the second A elastic frame grooves 362 is that the elastic frames 200 are formed on the outer surface 100 The elastic frames 200 are opened at predetermined angles to generate uniform elasticity because each elastic frame 200 disadvantageously maintains a minimum volume during folding. Therefore, the expanded angle of the elastic frames 200 should be adjusted so that the elastic frames 200 are parallel to each other. Since the elastic frame 200 seated in the second A elastic frame groove 362 can be spaced apart and rotated, it is possible to adjust the predetermined angle of expansion of the elastic frames 200 as described above. It is preferable that the second A elastic frame groove 362 is disposed on the edge side of the outer peripheral portion of the 1A engagement member and the 2A engagement member 330. [
