A connecting block 304 is fixedly connected to the upper end of the mounting plate 303. Connecting grooves 305 are symmetrically provided on both sides of the connecting block 304. A pressure sensor 312 is connected in the connecting groove 305. Connecting plates 301 are symmetrically fixedly connected to the upper end of the base 1.
