As the further improved technical scheme of this utility model, also including trocar sheath, the stainless steel tube is arranged on institute
The inside of trocar sheath is stated, the inner surface of the trocar sheath is fixedly connected with the outer surface of the stainless steel tube.
As the further improved technical scheme of this utility model, length of the length for passing through steel pipe than stainless steel tube
Long, the length for passing through steel pipe is longer than the length of trocar sheath.
Used as the further improved technical scheme of this utility model, the inner surface of the trocar sheath passes through the connection side of welding
Formula is fixedly connected with the outer surface of the stainless steel tube.
Used as the further improved technical scheme of this utility model, the inserts are epoxy iron ore.
Used as the further improved technical scheme of this utility model, the inside of the steering tube passes through the connected mode of welding
It is connected with multiple guide plates.
The steering tube bent in this utility model provides good steering for external prestressed cable and is oriented to；And pass through steel
The contact of the inner surface activity of the outer surface of pipe and stainless steel tube is so as to realizing that passing through steel pipe can occur in the inside of stainless steel tube
The phenomenon for moving left and right, when deformation is produced because of reasons such as temperature changes, passing through steel pipe can occur to fit in the inside of stainless steel tube
Answering property moves left and right phenomenon, increased the service life of this utility model and box beam；And the steel pipe of passing through of the present utility model
The setting of diameter can change according to the flexibility of steering tube and length；Trocar sheath of the present utility model is connected with external device
Connect, it is to avoid this utility model occurs the suitable obscission that produces upon displacement；Steering tube of the present utility model is passing through steel
The space passed through between steel pipe and steering tube is filled by inserts as obtained by the calculating of correspondence turning point in position inside pipe
So as to the position of fixed steering tube, can be very good to adapt to the different requirements of different turning points.
