[0029] An inner plate layer 16 is clamped on the back of the protector main body 8 , and a rear through hole 17 is opened on the front of the inner plate layer 16 .

[0030] An expandable locking ring 22 is clamped at the bottom of the square protective shell 1, and an expansion ball 23 is clamped inside the expandable locking ring 22. The top of the expansion ball 23 is connected to a connecting shaft 21, and the top of the connecting shaft 21 is threadedly connected to a sliding shield 19.

[0031] A sliding opening 18 is provided on the back of the square protective shell 1 , and heat dissipation holes 20 are provided inside the sliding opening 18 . A sliding shield 19 is slidably connected to the sliding opening 18 . Specific embodiment 2:

[0033] Reference Figure 1-4 The protector body 8 is an existing device. The components in this utility model are mainly used to protect the protector body 8. After the protector body 8 is installed in the square protective shell 1, the protector body 8 and the inside of the square protective shell 1 are in contact with each other. The display 12 on the front of the protector body 8 can be directly controlled by the control key 13. The outer card shell 4 is used to protect the front of the protector body 8. The inner protective layer 14 in the outer card shell 4 is elastic and will protect the end of the protector body 8. When installing the outer card shell 4, press the telescopic adjustment head 10 in four directions at the same time, and then put the outer card shell 4 on the square protective shell 1. After that, the telescopic adjustment head 10 will pop out from the lock mouth 15 and be fixed by the limiting round head 11, so that the entire protector body 8 is wrapped and protected.

[0034] At the same time, an anti-fall structure is installed on the outside. The sheath 5 outside the external frame 2 is connected through a shock-absorbing connecting column 3. The sheath 5 is made of plastic material, which can enhance the anti-fall effect of the overall assembly.

[0035] The existing protector body 8 has a strong sealing performance, so the heat dissipation effect is poor. In this device, the heat dissipation holes 20 are automatically opened for heat dissipation. The rear through holes 17 on the surface of the inner plate layer 16 installed on the back of the protector body 8 can ensure that the heat in the protector body 8 is dissipated. The heat in the protector body 8 will first be dissipated into the square protective shell 1. The expansion ball 23 in the square protective shell 1 is a heat-sensitive material and will expand when heated. The expandable locking ring 22 has elasticity and will limit it. After the expansion ball 23 expands, the connecting shaft 21 connected to the top will rise, and the connecting shaft 21 will push the slide upward after rising. The shield plate 19 is moved to expose the heat dissipation holes 20 on the sliding opening 18, so that the heat dissipated by the protector body 8 will be dissipated from the heat dissipation holes 20. When the internal temperature drops, the swelling ball 23 will shrink. After the swelling ball 23 shrinks, the connecting shaft 21 will also drive the sliding shield plate 19 to slide back, so as to cover the heat dissipation holes 20, so that the internal protector body 8 can be fully protected. The higher the temperature, the higher the expansion degree of the swelling ball 23, the more the sliding shield plate 19 slides, and the more heat dissipation holes 20 are exposed, so that the overall heat dissipation effect will be better.

[0036] The expansion ball 23 here is mainly made of heat-sensitive material and expands when heated.

[0037] In summary:

[0038] 1. The components in this utility model are mainly used to protect the protector body 8. After the protector body 8 is installed in the square protective shell 1, the protector body 8 and the inside of the square protective shell 1 are in contact with each other. The display 12 on the front of the protector body 8 can be directly controlled by the control key 13. The outer card shell 4 is used to protect the front of the protector body 8. The inner protective layer 14 in the outer card shell 4 is elastic and can protect the end of the protector body 8. When installing the outer card shell 4, press the telescopic adjustment heads 10 in four directions at the same time, and then put the outer card shell 4 on the square protective shell 1. After that, the telescopic adjustment head 10 will pop out from the lock mouth 15 and be fixed by the limiting round head 11, so that the entire protector body 8 is wrapped and protected.

[0039] 2. In this device, the heat dissipation holes 20 are automatically opened for heat dissipation. The rear through holes 17 on the surface of the inner plate layer 16 installed on the back of the protector main body 8 can ensure that the heat in the protector main body 8 is dissipated. The heat in the protector main body 8 will first be dissipated into the square protective shell 1. The expansion ball 23 in the square protective shell 1 is a heat-sensitive material and will expand when heated. The expandable locking ring 22 has elasticity and will limit it. After the expansion ball 23 expands, the connecting shaft 21 connected to the top will rise. After the connecting shaft 21 rises, it will push the sliding shield 19 upward, so that the heat dissipation holes 20 on the sliding mouth 18 will be exposed. In this way, the heat dissipation holes 20 on the slide 18 will be dissipated from the protector main body 8. When the internal temperature drops, the expansion ball 23 will shrink. After the expansion ball 23 shrinks, the connecting shaft 21 will also drive the sliding shield 19 to slide back, so as to block the heat dissipation holes 20, so that the internal protector main body 8 can be fully protected.
