[0025] like Figure 1-5 As shown, a steerable air extraction mechanical connection device comprises: a first end tube 10, a second end tube 20 and a plurality of intermediate tubes 30. One of the first end tube 10 and the second end tube 20 is used to connect to the air extraction port of an external air extraction device, and the other is used to connect to the interface of the position to be extracted. The intermediate tube 30 is used to extend the length of the whole.
[0026] The plurality of intermediate tubes 30 are connected in sequence, and two adjacent intermediate tubes 30 are connected by a steering structure 40. When two adjacent intermediate tubes 30 are connected by a steering structure 40, the shape of the entire air extraction device can be adjusted during use to adapt the connection. Similarly, the two ends of the plurality of intermediate tubes 30 forming a whole are connected to the first end tube 10 and the second end tube 20 respectively, and the first end tube 10 and the second end tube 20 are connected to the corresponding intermediate tube 30 respectively by the steering structure 40. The first end tube 10 and the second end tube 20 can also have a steerable connection with the intermediate tube 30 to increase the adaptability during use.
[0027] In some preferred embodiments, Figure 3-5As shown, a specific structural form of a steering structure 40 is given. The steering structure 40 includes a first cylinder 41 and a second cylinder 42 that are sleeved with each other, and a ball 43 is arranged between the first cylinder 41 and the second cylinder 42, so that the first cylinder 41 and the second cylinder 42 can realize circumferential rotation with each other. When used specifically, the first cylinder 41 and the second cylinder 42 are respectively connected to two intermediate tubes 30, or one of them is connected to the intermediate tube 30 and the other is connected to the first end tube 10, or one of them is connected to the intermediate tube 30 and the other is connected to the second end tube 20. When it needs to be rotated and deformed, the circumferential rotation between the first cylinder 41 and the second cylinder 42 can be used.
[0028] In some preferred embodiments, the surfaces of the first barrel 41 and the second barrel 42 are provided with ball grooves for accommodating the balls 43. The balls are accommodated by providing the ball grooves so that the arrangement of the balls 43 is sufficiently stable.

[0030] In some preferred embodiments, Figure 4 As shown, a limiting hole 421 is radially arranged on the second cylinder 42, and the diameter of the limiting hole 421 is smaller than the diameter of the ball 43. When the ball 43 falls into the limiting hole 421, the limiting is achieved, and then the specific position positioning is achieved during the rotation process.
[0031] In some preferred embodiments, a sealing ring 44 is provided between the first cylinder 41 and the second cylinder 42. The sealing ring 44 can be provided to achieve sealing and avoid leakage.
[0032] In some preferred embodiments, there are multiple sealing rings 44, and the multiple sealing rings 44 are arranged axially along the first cylinder 41. The sealing effect is improved by providing multiple sealing rings 44.
