[0032] Referring to Figure 2 , Figure 3 and Figure 4 , the two side plates 3 are provided with horizontal limiting grooves 33 on the side close to each other, and the limiting grooves 33 are above the supporting plates 31. Two locking blocks 5 are slidably connected in the horizontal direction in each limiting groove 33. The limiting groove 33 is a dovetail groove, which reduces the possibility of the locking block 5 sliding out of the limiting groove 33. The two locking blocks 5 are respectively located at the two ends of the mounting plate 4 in the width direction and lock the mounting plate 4. The two ends of the mounting plate 4 in the width direction are provided with first inclined surfaces 44.
