Abstract A linear control device for a shield machine comprises a device main body. The right side of the device main body is provided with a seat body. The seat body is provided with control openings, and a medium inlet is formed in the middle of the seat body. A first outlet and a second outlet are formed in the two sides of the device main body correspondingly. The medium inlet communicates with the first outlet and the second outlet through the control openings. A cylindrical cavity is formed in the device main body and internally provided with a plunger slidably matched with the device main body.A plurality of channels are formed in the plunger. The left side of the device main body is provided with a plurality of flow control devices. The flow control devices are used for controlling the medium flow of all the channels. The end of the right side of the plunger is provided with a matching part. The axial section of the matching part is in a parabola shape. The matching part and a throttling opening in the plunger
