Further preferably, a seat hole is formed in the front portion of the knob, and the spring and the pressing cover are located in the locking seat hole, so that the occupied space is reduced.

Further preferably, the outer edge of the knob is provided with the convex points which are uniformly distributed in the circumferential direction, so that the friction force of the knob is improved, and the knob is convenient to rotate.

Further preferably, the diameter-variable wheel disc is provided with jacks, and the radial pointer is provided with a bolt which is inserted into the corresponding jack.

The utility model has the advantages that:

1. owing to set up the knob in mount pad the place ahead, set up the reducing rim plate at the mount pad rear, the spliced pole of terminal surface passes the knob and is connected with knob circumference location before the reducing rim plate, rotates the reducing rim plate through rotatory knob, adjusts the diameter that corresponds adjusting pull rod contact point department on the reducing rim plate, adjusts adjusting pull rod axial displacement distance and adjusts the arc cam throw, and then adjusts kind spoon opening size, moreover, the steam generator is simple in structure, and convenient operation has shortened adjust time, has improved regulation efficiency.

2. Because the knob front end sets up the gland, set up the spring between knob and the gland, the terminal surface is equipped with the spliced pole before the reducing rim plate that sets up at the mount pad rear, the spliced pole passes in proper order behind mount pad, knob and the spring with the gland rigid coupling. Under static state, under the action of spring force, the gland and the reducing wheel disc connected with the gland have the trend of moving forwards, the knob has the trend of moving backwards, and the reducing wheel disc and the knob fasten and clamp the mounting seat, so that the reducing wheel disc is prevented from rotating, and the reducing wheel disc is circumferentially positioned.
