Further, referring to fig. 1, the electric start button assembly 8 is connected to the main knob 7, so that the electric start button assembly 8 can be prevented from occupying the space on the support plate 1, and the combined switch can be made compact. Referring to fig. 2, the choke valve switch, the oil switch 3, the starting switch 5 and the flameout switch 6 are arranged on the same side of the support plate 1 as the rotating block 2, the trigger end of the choke valve switch is arranged to be integrated with the rotating block 2, the trigger end of the oil switch 3 is detachably connected to the rotating block 2, and the oil switch 3 is turned on or off by the rotation of the trigger end; the trigger key is arranged on the rotating block 2. At this time, one side of the supporting plate 1, on which the main knob 7 is arranged, has a larger operation space, which is convenient for the use of the combined switch.

Alternatively, as shown in fig. 1, the trigger end of the choke switch is a cable block 23 fixed on the rotating block 2, the cable block 23 is connected with the choke (not shown) through the choke cable 4, and when the rotating block 2 rotates, the cable block 23 pulls the choke cable 4 to change the opening and closing conditions of the choke switch.

Further, referring to fig. 4 and 5, the trigger end of the oil switch 3 is a trigger rod 31 having a prism shape, for example, a rectangular rod. The trigger rod 31 is respectively matched with the rotating block 2 and the main knob 7 in a plugging manner to carry out circumferential limiting, so that the trigger rod 31, the rotating block 2 and the main knob 7 can synchronously rotate.

In addition, the trigger lever 31, the main knob 7, and the rotation block 2 are axially fixed by screw-locking of the fixing bolt 88. When the main knob 7 rotates, the rotating block 2 and the trigger rod 31 can synchronously rotate, and on-off control of the oil switch 3 is realized. As shown in fig. 5, the housing of the oil switch 3 is fixed to a locking bracket 16 fixedly provided on the support plate 1.

Further, referring to fig. 1 and 5, a gear fixing structure is disposed between the rotating block 2 and the supporting plate 1, so that the rotating block 2 can be respectively fixed at each preset gear to ensure the reliability of use.
