[0022] Please refer to Figures 1-4 , the present utility model provides a technical solution:

[0023] A passive multi-loop temperature sensor includes an elastic tie 101. One end of the elastic tie 101 is fixedly connected with a positioning side block 301. The bottom sides of both ends of the positioning side block 301 are jointly fixedly connected with a ring 303. A positioning seat 306 is clamped on the side of the ring 303 facing away from the positioning side block 301. One side of the positioning seat 306 is fixedly connected with a clamping slide rod 304. The clamping slide rod 304 is slidably connected with the ring 303. The top end of the clamping slide rod 304 is fixedly connected with a clamping piece 302. The end of the elastic tie 101 facing away from the positioning seat 306 passes through between the clamping piece 302 and the positioning side block 301. A plurality of position adjustment frames 201 are sleeved on the outer side of the elastic tie 101. The top end of one of the position adjustment frames 201 is fixedly connected with a sensor body 102. The side of the positioning seat 306 facing away from the positioning side block 301 is fixedly connected with a plurality of evenly distributed positioning gaskets 305. The side of the clamping piece 302 facing the positioning side block 301 is fixedly connected with an elastic clamping block 308. In this embodiment, the top side of the positioning seat 306 is provided with a plurality of symmetrically distributed clamping blocks 307, and a bayonet corresponding to each clamping block 307 is opened on the bottom side of the ring 303 to clamp the positioning seat 306 and the ring 303 together. At this time, the clamping piece 302 and the elastic clamping block 308 are pushed up, and the elastic tie 101 is fixed in the ring 303.

[0024] On the side of the elastic tie 101 facing away from the position adjustment frame 201, there are two symmetrically distributed slide rails 106.
