[0028] A placement plate 10, wherein the placement plate 10 is movably disposed in a placement groove formed on the fixing seat 1, a plurality of rollers 11 are fixedly disposed at the lower portion of the placement plate 10, and a side strip 12 is fixedly disposed on the side wall of the placement plate 10 by bolts, and the side strip 12 is clamped in a groove formed on the inner side wall of the placement groove;

[0029] A protective plate 13, wherein the protective plate 13 is movably arranged at the through-hole opened on the front side wall of the protective shell 2, and both sides of the protective plate 13 are movably inserted in the interlayer of the side wall of the protective shell 2, the placement plate 10 and the upper part of the fixing seat 1 are provided with matching arc-shaped sliding grooves, and an arc-shaped slider 14 is fixedly arranged at the lower part of the protective plate 13, and the arc-shaped slider 14 is movably arranged in the arc-shaped sliding groove, and a fixing block 19 is fixedly arranged at the right side position of the through-hole on the side wall of the protective shell 2 by bolts, and an insertion rod 20 is movably inserted on the fixing block 19, and a reset torsion spring 21 is fixedly arranged in the fixing block 19, one end of the reset torsion spring 21 is fixedly connected to the insertion rod 20, and a clamping block 23 is fixedly arranged on the insertion rod 20, and the clamping block 23 is matched with the handle on the protective plate 13 and is set to contact with each other, and the clamping block 23 can provide a limit for the protective plate 13 to prevent the protective plate 13 from moving at will and causing the through-hole to be opened at will.

[0030] Embodiment 2:

[0031] like Figure 4 As shown, the present embodiment is improved on the basis of the first embodiment, the blocking rods 15 are movably provided in the several strip grooves opened on the upper part of the placement plate 10, and the blocking rods 15 are fixedly penetrated with a rotating rod 16, and the rotating rod 16 is screwed through the inner wall of the strip groove by a bearing, and a bevel gear plate 18 is screwed through the shaft and the bearing in the placement plate 10, and a bevel gear 17 is fixedly sleeved on one end of the rotating rod 16, and the blocking rod 15 can be rotated to a vertical state by the rotating rod 16, so as to realize the protection of the gas tank placed on the placement plate 10.

[0032] When the utility model is used, the block 23 is pushed upward to disengage from the interference with the handle on the protective plate 13, so that the insertion rod 20 rotates and twists the reset torsion spring 21, and then the protective plate 13 is pushed to the left, so that the arc slide block 14 disengages from the arc slide groove on the placement frame and releases the block 23. At this time, the reset torsion spring 21 resets and drives the insertion rod 20 to rotate in the opposite direction, so that the insertion rod 20 drives the block 23 to return to the horizontal state. Then, the placement plate 10 can be pulled to the front side, and the placement plate 10 is disengaged from the placement groove under the action of the roller 11. At this time, there is no obstruction on the upper part of the placement plate 10, which is more conducive to placing the gas tank on the placement plate 10. After the gas tank is placed on the placement plate 10, the blocking rod 15 on either side can be flipped to the vertical state, and the blocking rod 15 drives the bevel gear 17 to rotate through the rotating rod 16, and through the cooperation of the bevel gear 17 and the bevel gear plate 18, several bevel gears 17 can rotate synchronously, thereby realizing several blocking rods 15 synchronously.

Then, the placing plate 10 is pushed into the placing groove by the roller 11, and the connecting pipe is connected to the gas tank. Then, the protective plate 13 is pushed to the right side, so that the arc-shaped sliding block 14 slides in the arc-shaped sliding groove on the placing plate 10 and the fixing seat 1 at the same time, so as to limit the placing plate 10. After the protective plate 13 closes the opening, the protective plate 13 can also be limited under the cooperation of the reset torsion spring 21, the plug 20 and the block 23. When used outdoors with wind, the openings of the mutually staggered structure opened on the heat dissipation outer cylinder 9 and the heat dissipation inner cylinder 8 can not only prevent the outdoor wind from blowing directly into the heat dissipation inner cylinder 8, but also reduce the impact on the flame emitted by the flame injection assembly 5, and to a certain extent prevent the loss of heat, but also can still ensure the sufficient oxygen required for the flame.

[0033] After adopting the above structure, the beneficial effects of this specific implementation are as follows:

[0034] 1. Through the cooperation of the fixing plate 7, the heat dissipation inner tube 8 and the heat dissipation outer tube 9, it is possible to prevent the outdoor wind from blowing directly on the flame, and to a certain extent, to prevent the loss of heat;

[0035] 2. Through the cooperation of the roller 11, the side strip 12, the protective plate 13 and the arc-shaped slider 14, the placement plate 10 can be removed from the fixing seat 1, so that the gas tank is more convenient to be placed on the placement plate 10, thereby improving the convenience of disassembly, replacement and use of the gas tank.

[0036] For those skilled in the art, they can modify the technical solutions recorded in the aforementioned embodiments and make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model should be included in the protection scope of the present utility model.
