Wherein, the protective device 7 comprises an outer net layer 71 and an inner net layer 72, a rubber strip 73 is installed between the outer net layer 71 and the inner net layer 72, the rubber strip 73 is made of rubber material with certain flame-retardant and fireproof effects, the rubber strip 73 can have certain buffering effect and simultaneously increase elasticity, when external foreign matters impact the outer net layer 71 at a certain speed, the rubber strip can accumulate force to rebound the foreign matters to achieve a flexible protection effect, and compared with rigid protection, the flexible protection has larger deformation degree, so that the impact energy caused by the external foreign matters is better in buffering effect and better in deformation resistance, and the impact energy from a single part can be extended to other positions of the outer net layer 71 and the inner net layer 72, an upper elastic ring body 74 is fixedly installed at the top ends of the outer net layer 71 and the inner net layer 72, the upper elastic ring 74 comprises a connecting strip, and the connecting strip is made of flexible material and has certain elasticity, in a tightening state in the using process, a pulling rope 75 is fixedly installed at the top of the upper elastic ring 74, a mud block 76 is installed at the other end of the pulling rope 75, the mud block 76 is fixedly installed on the channel 62, the mud block 76 is pasty before being installed on the channel 62, the end of the other end of the pulling rope 75 is wrapped by the pasty mud block 76, in order to ensure that the pulling rope 75 is fixed more firmly, a small ball can be installed at the other end of the pulling rope 75, the wrapped small ball is placed on the channel 62, when the upper elastic ring 74 is placed, the position is ensured to be pulled to one side far away from the circle center of the glass tube 4, then the pasty mud block 76 is dried, the pulling rope 75 is adhered in the channel 62 by the adhesion of mud, the upper elastic ring 74 is pulled, the pulling rope 75 and the mud block 76 are uniformly distributed on the upper surface of the upper elastic ring 74 along the circle center of the upper elastic ring 74 in the circumferential direction, and the number of the pulling rope 75 and the mud block 76 can be adjusted according to specific conditions, the standard of adjustment is according to the degree that pulls apart of last elastic ring 74, will go up elastic ring 74 and pull open, goes up the connecting strip other end of elastic ring 74 and is connected with gravity ring 77, and gravity ring 77 is located the outside of glass pipe 4, has a huge frictional force between the lateral wall of gravity ring 77 and glass pipe 4, utilizes the pulling force of frictional force and connecting strip, makes gravity ring 77 be in an upper position, and the pulling force of connecting strip mainly comes from the viscidity between clod 76 and channel 62.

In summary, during normal use, the protection device 7 outside the glass tube 4 is used for protection, when an external foreign object impacts the rubber strip 73, the outer mesh layer 71 and the inner mesh layer 720 cooperate with the middle rubber strip 73 to form a multi-directional full-angle protection for the outer side of the glass tube 4, and at the same time, because of more gaps of the meshes, the protection device can play a role in protecting the whole glass tube, and can ensure that an open fire is sensed by the glass tube 4 through the meshes, thereby reducing the blocking effect of the external protection device on the open fire, and simultaneously, the protection device can flexibly protect the glass tube, and has a larger buffering capacity on the external foreign object, and simultaneously, the rubber strip 73 can increase the elasticity and increase the buffering effect, once the external fire catches fire, the open fire can transmit to the glass tube 4 through the outer mesh layer 71 and the inner mesh layer 72, so that the glass tube 4 expands and explodes, fragments of the glass tube 4 splash outwards under the impact energy, and then be caught by the outer mesh layer 71, The inner net layer 72 rebounds, and is collected in an enclosing ring formed by the outer net layer 71 and the inner net layer 72, at this time, as the glass tube 4 disappears, the friction force of the gravity ring 77 disappears, the gravity ring 77 has a tendency of downwards and facing the inside of the inner net layer 72, then the upper clamping seat 3 can fall downwards due to lack of supporting force, in the setting process, in order to avoid the situation that the upper clamping seat 3 can not completely fall, during the setting process, the height of the circular truncated cone in the disc body 61 can be set higher than the height of the upper clamping seat 3, so that high-pressure water can flow out from a gap between the choke column 1 and the upper clamping seat 3, the high-pressure water flow after flowing out can impact the mud block 76 under the guidance of the channel 62, as the mud block 76 is made of mud, and can melt and fall off after being impacted by water, so that the outward pulling force of the upper elastic ring 74 disappears, under the gravity action of the gravity ring 77 and the elastic force of the upper elastic ring 74, to inner mesh layer 72 center drop partially, and lower cassette 5 on lower connecting seat 2 is owing to lack the power of supporting for whole hand has collected the protector 7 of glass pipe 4 piece, is washed down by high pressure water, makes the glass piece by complete collection in the net bag, avoids glass to be strikeed everywhere in the room, reduces the potential safety hazard that the glass piece brought.

The using method of the invention is as follows:

when the glass tube is normally used, the protection effect is realized by mainly utilizing the protection device 7, when external foreign matters impact the rubber strips 73, the outer net layer 71 and the inner net layer 72 are matched with the rubber strips 73 in the middle to form multidirectional all-angle protection on the outer side of the glass tube 4, meanwhile, because the gaps of grids are more, the glass tube can be ensured to be sensed by the glass tube 4 through the grids while the whole protection is realized, the double-layer flexible protection is realized, meanwhile, the rubber strips 73 increase the elasticity and increase the buffer effect, once the external part catches fire, the open fire is transmitted to the glass tube 4 through the outer net layer 71 and the inner net layer 72 at the moment, so that the glass tube 4 is expanded and exploded, fragments of the glass tube 4 splash outwards under the action of impact energy, then are rebounded by the outer net layer 71 and the inner net layer 72, are collected inside a surrounding ring formed by the outer net layer 71 and the inner net layer 72, at the moment, because the glass tube 4 disappears, the friction force of the gravity ring 77 disappears, the gravity ring 77 has a tendency of falling downward and facing the inside of the inner net layer 72, then the upper clamping seat 3 can fall downward due to lack of supporting force, in order to avoid the situation that the upper clamping seat 3 can not fall completely in the setting process, high-pressure water can flow out from the gap between the choke post 1 and the upper clamping seat 3, the high-pressure water flow after flowing out can impact the mud block 76 under the guidance of the channel 62, the mud block 76 is made of mud and can be melted and fall off after being impacted by water, so that the outward pulling force of the upper elastic ring 74 disappears, the upper elastic ring 74 falls downward toward the center of the inner net layer 72 under the gravity action of the gravity ring 77 and the elastic force of the upper elastic ring 74, and the lower clamping seat 5 on the lower connecting seat 2 lacks of resisting force, so that the whole hand collects the protective device 7 of the fragments of the glass tube 4 and is flushed down by the high-pressure water, so that the glass fragments are completely collected in the grid bag and fall off under the impact of high-pressure water.
