[0054] As mentioned above, the bag body 2 is a disposable object. When in use, pressure is applied to the outer plastic bag, such as pressing, rubbing or squeezing.

[0057] Embodiment 4:

[0058] The difference between this embodiment and the third embodiment is that the bag body 2 is a plastic bag, and a water bag and a coolant bag are arranged inside the bag.

[0060] Embodiment five:

[0061] The difference between this embodiment and the third embodiment is that the bag body 2 is a plastic bag, and a water bag and a coolant bag are arranged inside the bag. A refrigerant is arranged inside the coolant bag. The refrigerant includes the following raw materials in weight percentage: 47% ammonium chloride, 48% ammonium nitrate, and 5% sodium carboxymethyl cellulose. The refrigerant is in granular form.

[0063] Working principle:

[0064] Take the disposable bag body 2, and apply pressure to the outer plastic bag, such as pressing, rubbing or squeezing. After the pressure is applied, because the water bag and the coolant bag are relatively thin, the water bag and the coolant bag can be broken by the pressure, so that the water and the coolant are dissolved. In a short time, the coolant will be completely and quickly dissolved in the water, and its chemical properties will be exerted to quickly absorb heat to achieve the purpose of cooling. The bag body 2 is placed in the bag box 1, and the sealing cover 8 is closed;

[0065] By passing the arm through the strap 9, the heat conducting plate 6 and the support 11 wrap the arm, and by turning the knob 102, the worm 103 is driven to rotate, which can drive the worm wheel 104 to rotate, so that the gear 106 is rotated, and then the two racks 107 are driven to move synchronously and in the opposite direction (inside), so that the strap 9 can be tightened on the arm, and the stepless length adjustment is realized, which is convenient and fast, and has self-locking property, and there is no need to worry about loosening;

[0066] Secondly, the bag body 2 can be cooled again by the cooling plate 4 to control the ice compress temperature, and the real-time temperature can be detected by the temperature sensor 5 and displayed in conjunction with the display 13.
