the linkage state or the non-linkage state of the fourth rotating shaft and the fifth rotating shaft is used for adjusting the pressurization or non-pressurization of the first pipeline or the second pipeline,

when pressurization is not needed, the limiting mechanism is in a starting state, the first rotary disc, the second rotary disc and the third rotary disc are in a concentric circle state, when the fourth rotary shaft rotates, the second rotary disc and the third rotary disc are driven to rotate together, so that the purpose that the third rotary disc does not move is achieved, when the third rotary disc does not move, the swing rod cannot be started to work, when the swing rod does not work, pressurization is not performed on the pressurization chamber, and therefore the purpose that the first pipeline or the second pipeline cannot be pressurized is achieved;

when pressurization is needed, the limiting mechanism firstly relieves the limiting of the fourth rotating shaft and the fifth rotating shaft; then, the fourth rotating shaft drives the gear to rotate when rotating, the gear is meshed with the toothed plate, so that in the state shown in fig. 9, the gear moves to the left side on the right side of the third movable groove, that is, the second rotating disc drives the third rotating disc to move beyond the right side, so as to reach the state shown in fig. 8, and at this time, the circle centers of the first rotating disc and the second rotating disc are separated; the first limiting column arranged on the second rotary table and the fourth movable groove arranged on the first rotary table are matched with each other, so that the separation gap between the first rotary table and the second rotary table is limited in the adjustment process of separating the circle centers of the first rotary table and the second rotary table, and the separation distance between the first rotary table and the second rotary table is ensured to be the maximum separation distance between the two rotary tables;

secondly, the limiting mechanism is started again to limit the fourth rotating shaft and the fifth rotating shaft, so that the fourth rotating shaft and the fifth rotating shaft are linked, when the fourth rotating shaft and the fifth rotating shaft are linked again, the fourth rotating shaft rotates to drive the gear to rotate, and the gear drives the toothed plate to be meshed; due to the fact that the first rotary table and the second rotary table are spaced, when the gear rotates, the first rotary table, the second rotary table and the third rotary table can swing together, swing rods connected to the circumferential outer wall of the third rotary table can further swing, the second sliding block can reciprocate on the sliding rail when the swing rods swing, and then the movable rod connected to the other end of the second sliding block drives the movable plug to reciprocate in the pressurizing cylinder;

therefore, the purpose of pressurizing the pressurizing cylinder by using the movable plug is realized, and the gas-liquid pressure is transmitted to the second pipeline 24 or the fourth pipeline through the pressurizing cylinder through the third pipeline;

when the second pipeline is pressurized, the clamping bag can be inflated conveniently, so that the clamping bag can be expanded, the expanded clamping bag can be clamped by the first clamping groove of the clamping plate, and the first pipelines with different pipe diameters can be clamped and fixed;

when the fourth pipeline is pressurized, the pressurized gas-liquid pressure can be collected to the pressurizing chamber and then is shunted to the part needing to be pressurized through the pressurizing chamber; for example, when the pressure of the second pipeline is insufficient, the pressure of the pressure chamber can be used for secondary pressurization, so that the purpose of inflating the first cavity and the second cavity of the clamping bag is achieved; or the first pipeline can realize the purpose of air flow pressurization in the process of oxygen delivery or infusion, and the purpose of oxygen flow enhancement or infusion flow acceleration is realized.

The electromagnet is connected with the switch through a lead, and the electromagnet is firstly operated to be opened or closed through the switch, so that the purpose that the limiting mechanism can limit or relieve the limiting is achieved;

when the limiting is needed, the switch is utilized to start the electromagnet, so that the electromagnet adsorbs the T-shaped rod of the fixture block, the T-shaped rod of the fixture block is clamped into a third clamping groove of the fourth rotating shaft, and the purpose of clamping the fourth rotating shaft and the fifth rotating shaft is achieved;

when the limiting is not needed, the switch is utilized to close the electromagnet, the electromagnet loses the magnetic effect, the third spring can enable the T-shaped rod of the clamping block to be ejected out of the third clamping groove of the fourth rotating shaft, so that the purpose of disengaging the fourth rotating shaft from the fifth rotating shaft is achieved, and the purpose of rotating the fourth rotating shaft in the fifth rotating shaft is achieved. Therefore, the purpose of adjusting the fourth rotating shaft and the fifth rotating shaft by using the limiting mechanism is achieved, and the purpose of pressurizing or non-pressurizing the pressurizing mechanism is achieved according to the adjustment of the fourth rotating shaft and the fifth rotating shaft.

The pressurizing mechanism can also be used for clamping the first pipeline by utilizing the first clamping groove of the clamping block without pressurizing when the first pipeline is a large-diameter pipeline;
