A limiting groove 1811 is opened on the top of the limiting seat 181, and the limiting seat 181 passes through between the pressure plate 17 and the upper beam 10, and the pressure plate 17 is inserted into the limiting groove 1811; a bottom plate 184 is fixed at the bottom end of the plurality of partitions 182, and the bottom plate 184 is inserted into the fixing groove 141; the partition 182 is fixedly connected to the bottom plate 184 and the limiting seat 181 by bolts.

[0030] In this embodiment, tie rods 183 are fixed between the plurality of partitions 182 at both upper and lower sides, and the tie rods 183 are fixedly connected to the partitions 182 by bolts. The arrangement of the tie rods 183 increases the connection strength between the plurality of partitions 182 and ensures the connection stability between the partitions 182.

[0031] In this embodiment, the plurality of partitions 182 are linearly distributed at equal intervals, and the plurality of partitions 182 are all made of stainless steel. The partitions 182 made of stainless steel have the advantages of high structural strength and corrosion resistance, which ensures the service life of the partitions 182.

[0032] In this embodiment, two limit rods 131 are fixed to the front end surface of the reinforcing plate 13, and the limit rod 131 is located between the two pull rods 183 and presses against the pull rod 183.
