1. A gas switch capable of adjusting fire intensity finely, comprising: A switch body including a base and a cover, in the base, there is a conical valve chamber with an opening at one end and a gas intake hole as well as a gas outlet hole connected through the valve chamber, while the cover is placed at the side opposite to the valve chamber of the base, and a guide is installed inside the cover; A valve set, which is installed and rotates inside the valve chamber and includes a valve, on the axis of the valve, there is a through channel, and on the surface of it, there are a guide slot, a gas intake hole and a control port connected with the channel, and the control port is installed inside the channel; a pilot valve that can move elastically inside the valve with one control section installed at one end of it, which always seals the control port when the pilot valve is not pushed; A drive component installed on the cover, containing a rotating rod that rotates round and moves along the same shaft of the valve set, a guide rod installed on the rotating rod and closely linked with the surface of the guide, which is used to make the guide rod move on the surface of the guide when the rotating rod revolves and further causing the rotating rod to generate axial displacement, a regulating block which can move along the rotating rod and closely connected with the pilot valve; and A connecting component for linking the drive component with the valve set flexibly, which is used to transfer actions of the drive component to rotate the valve and relocate the pilot valve. 2. The gas switch capable of adjusting fire intensity finely as defined in claim 1, wherein a containing hole is opened on the cover and the drive component goes through the containing hole to correspond with the valve set, and the guide surrounds the containing hole in a protrusive way. 3. The gas switch capable of adjusting fire intensity finely as defined in claim 2, wherein the guide includes an inclining section, a first flat section, a declining section and a second flat section that reach out, the inclining section gradually approaches the valve set in an inclined way, while the declining section moves gradually faraway from the valve set in an inclined way. 4. The gas switch capable of adjusting fire intensity finely as defined in claim 1, wherein there is an axle hole passing through the rotating rod and the regulating block is installed inside the axle hole and close to the pilot valve. 5. The gas switch capable of adjusting fire intensity finely as defined in claim 4, wherein a connecting component is installed at one end of the pilot valve and suitable for being connected with the pilot valve with low friction. 6. The gas switch capable of adjusting fire intensity finely as defined in claim 5, wherein the cross section of the connecting component is roughly in the conical shape. 7. The gas switch capable of adjusting fire intensity finely as defined in claim 5, wherein the cross section of the connecting component is roughly like a curve. 8. The gas switch capable of adjusting fire intensity finely as defined in claim 4, wherein internal threads are installed inside the axle hole of the rotating rod at the end that is close to the pilot valve for the purpose of allowing the regulating block to screw into it movably. 9. The gas switch capable of adjusting fire intensity finely as defined in claim 1, wherein the connecting component comprises two contact plates which are installed at the opposite side of the rotating shaft and the valve, a spring which is connected between the two contact plates but at the outward side of the rotating shaft and valve, so that the valve can be rotated by the rotating shaft as it revolves. 10. The gas switch capable of adjusting fire intensity finely as defined in claim 1, wherein the guide rod is a round one.
