In this structure, the spout plays direction limiting displacement, and its length is used for restricting the stroke of inner bag board, and specific length can be along with actual engineering demand, and when the furnace body takes place to vibrate, first connecting portion slides along the horizontal direction under spout and the cooperation of overhanging part, takes place the friction power consumption between inner bag board and interior splint, the outer splint, reaches the antidetonation purpose. In addition, the bolt in the first connecting portion not only plays a role in connecting the furnace body, but also can change the friction force between the liner plate and the inner clamping plate and between the liner plate and the outer clamping plate by adjusting the screwing degree of the bolt.
Preferably, the opposite surfaces of the inner clamping plate and the outer clamping plate are rough surfaces so as to increase friction energy consumption. The roughened surface may be provided in a variety of ways, such as frosting, embossing, and the like.

Detailed Description
The utility model is further described below with reference to the drawings and specific examples.
Example 1

More specifically, as shown in fig. 3 to 5, the first connecting portion 1 includes an inner clamping plate 11 and an outer clamping plate 12 that are disposed opposite to each other, a sliding groove 121 is formed on a surface of the outer clamping plate 12 in a horizontal direction, and opposite surfaces of the inner clamping plate 11 and the outer clamping plate 12 are roughened surfaces that are subjected to frosting treatment; the inner surface profile of the inner clamping plate 11 is matched with the outer surface of the furnace body 3, and the first connecting part 1 is fixedly connected with the furnace body 3 through four symmetrically distributed bolts 13 which sequentially penetrate through the outer clamping plate 12 and the inner clamping plate 11.
The second connecting portion 2 includes a liner plate 21 sandwiched between the inner clamping plate 11 and the outer clamping plate 12, and an outer extension piece 22 disposed on the outer surface of the liner plate 21, penetrating through the sliding groove 121, and having an outer end fixedly connected to the support structure 4, the support structure 4 is a frame structure having a plurality of columns, the outer extension piece 22 includes two cantilever arms 221 that clamp the columns therebetween, specifically, the end of the cantilever arm 221 is fixed to the columns by bolts to realize clamping fixation; the cantilever 221 is perpendicular to the outer surface of the liner plate 21, and has a sliding distance from the chute 121.
The working mechanism of this embodiment is as follows: when the furnace body 3 and the supporting structure 4 are relatively displaced, the second connecting part 2 of the guiding device is static relative to the supporting structure 4, the first connecting part 1 is static relative to the furnace body 3, the first connecting part 1 realizes movement in the horizontal direction through the cooperation of the cantilever 221 and the chute 121, and the guiding device converts the kinetic energy of the structure into heat energy at the moment due to the existence of the friction surface. When the vibration of the furnace body 3 is small, the furnace body 3 swings to the original position under the action of gravity, and the guiding device automatically returns to the original position; when the furnace body 3 vibrates greatly and swings severely, the first connecting portion 1 will slide until the cantilever 221 hits the end of the chute 121, and cannot slide further, the second connecting portion 2 will limit the relative displacement between the furnace body 3 and the supporting structure 4 in the elastic range, and the second connecting portion 2 will undergo plastic deformation to consume energy through friction energy if the vibration exceeds the range.
