[0016] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0017] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0018] Embodiment 1, as Figure 1-2 As shown, the utility model provides a structure for fast lifting of multi-point thermocouple protection sleeves, including a junction box 1, a thermocouple core 2 is fixed to the bottom end of the junction box 1, a connecting plate 9 is provided below the junction box 1 on the outside of the thermocouple core 2, a protection sleeve body 5 is fixed to the bottom end of the connecting plate 9 on the outside of the thermocouple core 2, and a device guardrail 7 is installed at one end of the protection sleeve body 5.
