At edge, the escape pipe quantity has two, two described escape pipe one end are connected to the interface tube, the other end then with the electricity
The gas outlet of magnet valve is connected to, and the interface tube is also connected to the air-casing in the snake bend.
In order to further increase the practicability of the snakelike executor stiffness variable tube based on MIS, the remote controler
On be additionally provided with power switch and work light.
In order to further increase the practicability of the snakelike executor stiffness variable tube based on MIS, the control is opened
Pass is electrically connected with the solenoid valve and the battery case.
In order to further increase the practicability of the snakelike executor stiffness variable tube based on MIS, the air inlet pipe
Quantity also has two, one end of two air inlet pipe is connected to the air inlet of the solenoid valve, the other end then with it is described miniature
The gas outlet of air pump is connected to.
In order to further increase the practicability of the snakelike executor stiffness variable tube based on MIS, the wire-passing tube
Road is located at the snake bend middle inside, and the air-casing is located in the snake bend inner wall.
Beneficial effect is: should be led to based on the air-casing is provided in the snakelike executor stiffness variable tube of MIS
Cross that control the air pressure of gas in the air-casing different rigid have the snakelike executor stiffness variable tube based on MIS
Degree, to realize the rigidity for freely adjusting the snake bend, feature-rich, practicability is good.

Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing:
As shown in Figure 1-Figure 3, a kind of snakelike executor stiffness variable tube based on MIS, including snake bend 1,
1 side of snake bend is provided with escape pipe 2, and gas of the escape pipe 2 for micro air pump 6 to be generated enters air-casing 12 through solenoid valve 3
It is interior to prop up snake bend 1, it is provided with solenoid valve 3 on escape pipe 2, solenoid valve 3 is for controlling 2 outlet of escape pipe, on solenoid valve 3
It is provided with battery case 4, air inlet pipe 5 and conducting wire 7, air inlet pipe 5 is for connecting micro air pump 6 and solenoid valve 3, the connection of 7 end of conducting wire
