Through the setting of the positioning assembly, when the two handles 31 are close to and in contact with each other, the two first clamping plates 32 will clamp the two handles 31 to prevent the handles 31 from automatically popping open, thereby ensuring the stability of the person holding the two handles 31. Only when the two ends of the first clamping plates 32 that are away from each other are pressed at the same time can the two handles 31 be released from the position.

[0050] like Figure 1 , Figure 2 , Figure 3 , Figure 8 As shown, an adjusting slot 43 is provided on the protective plate 21, and an adjusting plate 41 is slidably provided on the inner wall of the adjusting slot 43. The protective plate 21 is rotatably connected to the middle part of the connecting frame 29 through the adjusting plate 41. A limiting assembly for adjusting the protective plate 21 up and down is provided in the adjusting plate 41.

[0053] The two first clamping plates 32 are used to automatically lock the two handles 31 to prevent the two handles 31 from separating. At the same time, the two first connecting rods 27 on the two handles 31 will push the left and right connecting plates 26 to move, and the sleeve rod 25 will further push the connecting tube 24 to move, so that each L-shaped slide plate 23 slides in the corresponding first slide groove 22, so that the left and right two sets of protective plates 21 slide to the corresponding sides of the gas distributor body 1, so that the two protective plates 21 on the left can protect the display screen of the gas distributor body 1, and the two protective plates 21 on the right will protect the interface of the gas distributor body 1, thereby avoiding damage to the gas distributor body 1 caused by accidental falling of the gas distributor body 1. When the gas distributor body 1 needs to be carried and moved, people The staff can directly hold the two handles 31 to lift the gas distributor body 1 for carrying, or slide out the universal ball 54 at the bottom of each protective plate 21, then flip the two telescopic sleeves 62 upwards, and then clamp the handles 64 to the clamping rod 67 through the limit groove 68, and finally adjust the extended length of the handles 64. The staff can hold the handles 64 to place the gas distributor body 1 on the ground for sliding and carrying, which can not only prevent the gas distributor body 1 from falling, but also reduce the weight of the gas distributor body 1 for staff to take. When using the gas distributor body 1, the two telescopic sleeves 62 are stored in the corresponding storage chambers 61, and then the two first clamping plates 32 are released to position the two handles 31, so that the two handles 31 are separated from each other, and the first connecting rod 27 pulls the connecting plate 26 to move, and finally each protective plate 21 slides to the front and back of the gas distributor body 1 to ensure the normal use of the gas distributor body 1.
