It should be particularly noted that the assisting mechanism of the present embodiment assists the doctor to manually press the foot controller A2 to open or close; the circuit control system can also be adopted to control the first push rod 1 and the second push rod 2 to automatically extend and retract so as to automatically open and retract the foot controller A2, and the circuit control system controls the first push rod 1 and the second push rod 2 to extend and retract, and the extension and retraction movement is the same as that of the foot controller A2 manually pressed by an assistant doctor.

In summary, the implementation process of this embodiment is as follows:

1. when the foot controller A2 is turned over downwards and opened, the first push rod 1 extends and moves, an obtuse angle formed between the first push rod and the first turning arm A21 is gradually increased, and the formed jacking force is gradually reduced; the second push rod 2 contracts and moves, an acute angle formed between the second push rod and the second turnover arm A22 is gradually increased, and the formed jacking force is gradually increased;

2. when the foot controller A2 is turned downwards and folded, the first push rod 1 contracts and moves, an obtuse angle formed between the first push rod and the first turning arm A21 is gradually reduced, and the formed jacking force is gradually increased; the second push rod 2 extends and forms a gradually decreasing acute angle with the second overturning arm A22, and the formed jacking force becomes gradually smaller.

Therefore, the present embodiment has the following advantages:

1. the pushing force formed by the two push rods on the foot controller effectively prevents overlarge pressing force, ensures that the foot controller is stably turned downwards and opened, prevents collision and effectively prolongs the service life of the foot controller;

2. the resultant force is stable through the change of the jacking force formed by the two push rods when the foot controller is adjusted up and down, so that a doctor can conveniently control the force used for opening or retracting the foot controller each time;

3. when the foot controller is turned over, the two push rods perform adaptive telescopic motion, so that the foot controller cannot be damaged in a collision manner;

3. when the foot controller is folded, the foot controller is locked by the pushing force of the two push rods, so that the foot controller is prevented from falling accidentally;

4. can form spacing to foot controller upset motion, prevent the colliding with that excessive upset caused.
