[0029] A guide groove 7 is provided at the bottom of the special gas cabinet body 1, a limit block 5 is slidably arranged at the bottom of the special gas cabinet body 1, and a limit mechanism 4 is arranged inside the special gas cabinet body 1;

[0030] The limiting mechanism 4 includes an adjusting rod 401, and the adjusting rod 401 is arranged inside the special gas cabinet body 1, and the outer side of the adjusting rod 401 is evenly sleeved with an adjusting block 402, both ends of the adjusting rod 401 are sleeved with a driving bevel gear 403, and one side of the driving bevel gear 403 is meshed with a driven bevel gear 406, and both sides of the driving bevel gear 403 and the driven bevel gear 406 are fixed with a clamping block 407, the interior of the driven bevel gear 406 is penetrated by a driven shaft 404, and the outer side of the driven shaft 404 is sleeved with a moving block 405;

[0031] The outer side of the adjusting rod 401 is provided with two sets of opposite external threads, and the two sets of opposite external threads are symmetrically distributed;

[0032] The adjusting block 402 slides inside the guide groove 7, and the limiting block 5 is slidably connected with the guide groove 7 and the special gas cabinet body 1 through the adjusting block 402;

[0033] There are multiple groups of card blocks 407, each group of card blocks 407 is provided with two, and the cross-sections of the multiple groups of card blocks 407 are all annular;

[0034] Specifically, Figure 1 , Figure 2 As shown, when in use, by screwing the adjusting rod 401, on the one hand, the limiting block 5 is driven to limit and fix the bottom bottle body of the special gas bottle under the action of the adjusting block 402, and on the other hand, the driven shaft 404 is driven to rotate under the action of the active bevel gear 403 and the driven bevel gear 406, thereby driving the clamping block 6 to move downward under the action of the moving block 405, so that the clamping block 6 is sleeved at the bottle mouth of the special gas bottle, thereby further limiting and fixing the special gas bottle, thereby improving its practical firmness;

[0035] Fixed columns 2 are slidably arranged on both sides of the special gas cabinet body 1, and extrusion springs 8 are fixed inside the fixed columns 2;

[0036] Two extrusion springs 8 are provided, the two extrusion springs 8 are symmetrically distributed, and the two extrusion springs 8 are both in a stretched state inside the fixed column 2;
