[0025] When working, when bottom film 1 is stretched, the both sides of bottom film 1 will move to the direction of compression band 2, so that side band 3 is pressed, and side band 3 transmits the pressure to compression band 2, so that the both sides of compression band 2 bear the pressure, thereby reducing the amplitude of the both sides of bottom film 1 moving to compression band 2.

[0026] Please refer to Figures 1-4 The utility model provides a technical scheme: a plurality of reinforcing strips 5 are connected to the upper surface of compression band 2, and the reinforcing strips 5 are made of hard plastic material.

[0027] When working, when side band 3 is pressed, force is simultaneously transmitted to compression band 2 and reinforcing strips 5, and the setting of the reinforcing strips 5 can improve the compression effect.

[0028] Please refer to Figures 1-4 The utility model provides a technical scheme: grooves 6 are arranged on the both sides of compression band 2, and the side bands 3 on the both sides are respectively inserted into the corresponding grooves 6.

[0029] When working, the setting of the grooves 6 can limit the side bands 3, prevent the position deviation of compression band 2 and side band 3, and ensure that the side bands 3 can transmit the pressure to compression band 2.
