continuously for multiple times, the pressing shell 65 is pressed downwards to drive the second piston 62 to move downwards, the second piston 62 moves downwards to compress air inside the second fixed shell 61, so that the air inside the second fixed shell 61 is compressed to the inner side of the high pressure resistant air pipe 67, then the pressing shell 65 is released, under the influence of the elasticity of the compression spring 63, the compression spring 63 drives the second piston 62 to move upwards to return to the original position, when the second piston 62 moves upwards, the outside air passes through the pressing shell 65 through the first large through hole 66 and then passes through the third one-way valve 64 to enter the inner side of the second fixed shell 61, so that the inside of the second fixed casing 61 is refilled with air, when the pressing shell 65 is pressed again, the air inside the second fixed casing 61 is compressed to the inside of the high pressure resistant air pipe 67, so that the external air is delivered to the inside of the inner sliding seal 41 through the high pressure resistant air pipe 67, the air enters the interlayer of the flexible rubber pipe 47 which is turned outwards, the part of the flexible rubber pipe 47 with the oval cross section is hereinafter referred to as the oval inner layer of the flexible rubber pipe 47, the turned-out part of the flexible rubber pipe 47 outside the oval inner layer is hereinafter referred to as the special-shaped outer layer of the flexible rubber pipe 47, the delivery of the external air to the inside of the inner sliding seal 41 through the high pressure resistant air pipe 67 refers to the delivery of the air to the part between the oval inner layer of the flexible rubber pipe 47 and the special-shaped outer layer of the flexible rubber pipe 47, by conveying air to the position between the oval inner layer of the flexible rubber pipe 47 and the special-shaped outer layer of the flexible rubber pipe 47, and fixing one end of the special-shaped outer layer of the flexible rubber pipe 47 at the outer side of the inner sliding sealing element 41, not only is an oval support surrounded by two semi-oval hard supports 48 which are in contact connection with each other between the oval inner layers of the flexible rubber pipe 47, so that the shape of the oval inner layer of the flexible rubber pipe 47 can be supported by the two semi-oval hard supports 48 which are in contact with each other, on the premise that the oval inner layer of the flexible rubber pipe 47 is supported by the semi-oval hard supports 48 to have a stable shape, the air is conveyed to the position between the oval inner layer of the flexible rubber pipe 47 and the special-shaped outer layer of the flexible rubber pipe 47, the oval inner layer of the flexible rubber pipe 47 can be influenced by air pressure to move, so that the oval inner layer of the flexible rubber pipe 47 is pushed by the air pressure, the oval inner layer of the flexible rubber tube 47 moves outwards, and the oval inner layer of the flexible rubber tube 47 gradually changes towards the special-shaped outer layer of the flexible rubber tube 47, so that the overall length of the special-shaped outer layer of the flexible rubber tube 47 is increased, when the oval inner layer of the flexible rubber tube 47 moves, the oval inner layer of the flexible rubber tube 47 drives the sliding inner frame 46 to move together, the sliding inner frame 46 moves to drive the connecting plate 45 to move, the connecting plate 45 moves to drive one end of the second soft rope 44 to move, so that the second soft rope 44 is drawn out from the outer side of the electric winding wheel 43, in the above way, when the extended length of the special-shaped outer layer of the flexible rubber tube 47 is long enough, namely the extended length of the special-shaped outer layer of the flexible rubber tube 47 is the same as the section length of the sealing sponge 53, the pressing of the shell 65 stops being continuously pressed, at this time, although the air inside the second fixed housing 61 enters the inside of the third fixed housing 71 through the second communicating tube 72, the air inside the third fixed housing 71 will not be discharged outside at this time, because the third piston 73 blocks the upper portion of the third fixed housing 71, thereby preventing the air inside the third fixed housing 71 from entering the second large through hole 77 of the upper portion of the third fixed housing 71, then the bag opening of the plastic bag 12 is inserted between the two sealing sponges 53, and the plastic bag 12 is sleeved on the outside of the special-shaped outer layer of the flexible rubber tube 47, then the first electric telescopic rod 51 is energized, after the first electric telescopic rod 51 is energized, the first pressing plate 52 is driven to move, the first pressing plate 52 moves to drive the sealing sponge 53 to move, the two sealing sponges 53 move towards each other to contact the flexible rubber tube 12, and make the plastic bag 12 cling to the surface of the outer layer of the flexible rubber tube 47, meanwhile, because the sealing sponge 53 has a groove with the same interface as the special-shaped outer layer of the flexible rubber tube 47, thereby the sealing rotating shaft 53 can cling to the outer layer of the sealing sponge 53 to the outer layer of the sealing sponge 12, thereby achieving good sealing performance, and preventing the plastic bag 12 from rotating, the reel 24 from rotating, and the rotating, thereby driving the reel 26 to rotate, and driving the rotating reel 22 to rotate, thereby driving the rotating reel to rotate, and driving the rotating reel to rotate, the rotating reel 26 to rotate, thereby driving the rotating reel 26 to rotate, the rotation of the rotating top cover 27 will drive the eccentric sliding column 28 to rotate, because the eccentric sliding column 28 slides inside the inner groove cross plate 33, and the inner groove cross plate 33 is connected with the inner sliding plate 32, the inner sliding plate 32 slides linearly inside the fixed linear base 31, so that the inner groove cross plate 33 can only move up and down, the reciprocating movement of the inner groove cross plate 33 will drive the transmission rod 34 to reciprocate, the transmission rod 34 will drive the first piston 35 to reciprocate, the reciprocating movement of the first piston 35 will draw the air inside the first fixed housing 37 to the outside, the suction manifold 391 is connected with the fixed seal housing 42, the inside of the fixed seal housing 42 and the oval inner layer of the flexible rubber tube 47 are also connected with the air inside the plastic bag 12, so that the air inside the plastic bag 12 can enter the suction manifold 391, the air inside the suction manifold 391 will enter the inside of the first communication tube 38, when the first piston 35 inside one of the first fixed housing 37 moves towards the first communication tube 38, the second one-way valve 39 is arranged, so as to prevent the air inside the first fixed housing 37 from entering the inside of the first communication tube 38, but when the first piston 35 moves towards the inside of the first communication tube 37, the first communication tube 38, the first one-way valve 37 will move, so that the air inside of the first fixed housing 37 will pass through the first communication tube 38, the first one-way valve 38, when the first one-way valve 35 moves towards the first communication tube 35, the first communication tube 38, the first one-way valve 37, the first communication tube 35 will move, the first one-way valve 37, so that the first one-way valve 37 will move, in this way, it is finally realized that the air inside the plastic bag 12 is drawn out to the outside, thereby realizing the vacuuming treatment of the inside of the plastic bag 12, after the first non-elastic soft rope 291 is stretched to the maximum stroke, the hand grasping the hand pulling handle 292 is released, at this time, the coil spring 24 drives the rotating cylinder 25 to rotate reversely, the rotating cylinder 25 rotates reversely to drive the rotating shaft 26 to drive the rotating top cap 27 to rotate reversely, the rotating top cap 27 rotates reversely to drive the eccentric sliding column 28 to rotate reversely, but the eccentric sliding column 28 rotates reversely to still reciprocate the inner groove transverse plate 33, according to the above principle, the air inside the plastic bag 12 can be drawn out, therefore, the discontinuous air drawing operation can be realized by the coil spring 24, when the air inside the plastic bag 12 reaches the target requirement, the button plate 76 is pressed, the electric power is supplied to the electric driven pulley 43 and the sealing sponge 53 immediately after the button plate 76 is pressed, the button plate 76 moves downwards to drive the third piston 73 to move downwards, the third piston 73 moves against the elastic force of the tension spring 74 to move downwards, the third piston 73 moves towards the inner side of the second flexible air-fixing rubber hose 71, the second air-fixing housing 71 and the inner side of the second rubber hose 47 can pass through the second flexible hose 47, thereby enabling the inner side of the second flexible hose fixing rubber hose 71 to pass through the inner side of the second rubber hose fixing hose 71, and the inner side of the second rubber hose fixing housing 71, and the second rubber hose fixing hose 47, the inner side fixing rubber hose fixing hose connecting hose 47, then the electric winding wheel 43 is electrified to wind the second soft rope 44 to lead the second soft rope 44 to draw the connecting plate 45 to move back, the connecting plate 45 drives the sliding inner frame 46 to move, the sliding inner frame 46 drives one end of the elliptical inner layer of the flexible rubber tube 47 to move back, thereby realizing that the special-shaped outer layer part of the flexible rubber tube 47 gradually changes to the elliptical inner layer of the flexible rubber tube 47, and simultaneously the elliptical inner layer of the flexible rubber tube 47 enters the inner side of the fixed seal shell 42 to be accommodated, the outer side part of the elliptical inner layer of the flexible rubber tube 47 is in sliding connection with the inner side of the inner sliding seal 41, thereby realizing that the air between the elliptical inner layer of the flexible rubber tube 47 and the special-shaped outer layer of the flexible rubber tube 47 is prevented from being discharged from the gap between the outer side part of the elliptical inner layer of the flexible rubber tube 47 and the inner side of the inner sliding seal 41, the second electric telescopic rod 54 drives the second pressing plate 55 to move after being electrified, the second pressing plate 55 drives the protrusion 56 to move, so that the two second pressing plates 55 and the two protrusions 56 move oppositely to clamp the sealing sponge 53, the position of the protrusion 56 arranged corresponds to the part of the groove of the sealing sponge 53 through the large pressure provided by the second electric telescopic rod 54, so that the part of the groove of the sealing sponge 53 can be flattened through the extrusion of the protrusion 56, the existence of the groove on the sealing sponge 53 can be reduced or visually eliminated, when the special-shaped outer layer of the flexible rubber tube 47 is not in contact with the plastic bag 12, the external air can be prevented from entering the inner side of the plastic bag 12 through the extrusion of the second pressing plate 55 and the protrusion 56, finally, the third electric telescopic rod 57 is electrified, and the third electric telescopic rod 57 can drive the third pressing plate 58 to move, the third pressing plate 58 moves to drive the heating and sealing wires 59 to move, and meanwhile, the heating and sealing wires 59 are electrified, the heating and sealing wires 59 are heated after being electrified, after the heating and sealing wires 59 are in contact with the plastic bag 12, the plastic bag 12 can be subjected to hot melting sealing, and the sealing after the vacuum pumping of the plastic bag 12 is completed, it is noted that the advantage that the overall length of the flexible rubber tube 47 is changed through the outward turning of the flexible rubber tube 47 is achieved, if the rigid rubber tube is directly drawn out from the inner side of the plastic bag 12 through the rigid pipe, under the condition that the sealing sponge 53 applies large pressure to the plastic bag 12, the rigid pipe which is directly drawn out is subjected to large resistance and is difficult to draw out, or after the rigid rubber tube is drawn out, certain damage is caused to the plastic bag 12, the overall length of the flexible rubber tube 47 is changed through the outward turning of the flexible rubber tube 47, so that the conventional sliding type drawing back is changed into rolling type drawing back, and the situation that the plastic bag 12 is damaged by sliding friction is not easy to occur.
