when the instrument enters the box body 1 and moves leftwards to drive the supporting plate 19 to move leftwards, a user can rotate the control handle 33 in advance and hang the control handle 33 on the supporting plate 19, so that the hydraulic control rack 32 can be meshed with the hydraulic control gear 31, after the position of the instrument is fixed, the user rotates the control handle 33, the hydraulic control rack 32 slides downwards under the action of gravity and is not meshed with the hydraulic control gear 31, at the moment, the volume of compressed inert gas in each pneumatic piston rod 22 is fixed, namely, the buffering effect is fixed, and the movement of the supporting plate 19 in the bumping process cannot influence the volume of the compressed inert gas in the pneumatic piston rod 22 any more;

when the instrument is bumped and moves leftwards, the supporting plate 19 moves leftwards along with the bumping, the two parallel damping connecting rods 20 are driven to move upwards and downwards away from each other respectively, so that the corresponding pneumatic piston rods 22 are pulled to move, the two pneumatic piston rods 22 are prevented from moving outwards under the action of inert gas in a closed sealed cavity formed by the ends of the two pneumatic piston rods 22 arranged in the pneumatic piston cylinder 21 and the inner wall of the pneumatic piston cylinder 21, the supporting plate 19 is kept stable, vibration is absorbed and relieved, and meanwhile, the damping springs 23 also play a role in buffering and damping, so that the instrument in the box body 1 is protected;

when a user pushes the instrument into the box body 1, the two pressing connecting rods 37 are opened when the instrument enters the box body 1, then the user shifts the two pressing supports 34 to enable the two pressing connecting rods 37 to return to the original positions under the action of coil springs of the pressing connecting rods 37 and to be pressed at the right end of the instrument under the action of the pressing springs 38, then the user rotates handles of the two pressing screw rods 35 to enable the pressing connecting rods 37 to be pressed on the instrument, the right end of the instrument is prevented from tilting, and therefore the instrument is fixed;

when the instrument is transported to a destination and needs to be pushed out of the box body 1, a user can rotate the screw driving gears 16 on the side of the box body 1 , under the action of the driving shaft 17, the two screw driving gears 16 synchronously rotate to drive the two corresponding screw driven gears 15 to synchronously rotate, the two one-way clamping seat screws 14 synchronously rotate to drive the two one-way clamping seats 11 to respectively move towards the direction away from the front wheel clamping seat 9, so that the one-way clamping plate 12 is separated from the contact with the rotating clamping plate 10, and the limitation on the rotating clamping plate 10 is relieved.
