Described self-locking mechanism comprises chock plate handle 2, chute 52 is had with on the air filter base of described chock plate side dorsad, the end of described chute 52 is communicated with the side of described transverse slipway 51, described chock plate handle 2 is slidably mounted in described chute 52, and described chock plate handle 2 is connected with the second resetting means in order to drive chock plate handle 2 to conflict on described slide block; Slider side wall near described chute 52 side has concave point, and the end of described chock plate 2 is provided with salient point, and described salient point coordinates with described concave point;
The elastic force of described second resetting means is greater than the elastic force of described first resetting means;
During pull-out chock plate handle 2, first resetting means drives described choke door-plate 32 to cut out by intake grill 55, the rotating arm 81 of described Carburetor 8 touches interlock with the other end of described slide block, when strengthening Carburetor throttle, the rotating arm 81 of described Carburetor 8 promotes described slide block, described slide block drives described choke door-plate 32 to be opened by intake grill 55, leave certain gap between the rotating arm 81 of now described slide block and described Carburetor 8.
Further, described concave point is trapezoidal groove 31, and described salient point is trapezoid boss 21.
Further again, described first resetting means is the first Returnning spring 4, and described second resetting means is the second Returnning spring 1; Described slide block has the first spring groove on along its length, described first Returnning spring 4 is installed in described first spring groove, one end of described first Returnning spring 4 contacts on the inwall of described first spring groove, and the other end of described first Returnning spring 4 contacts on described air filter base 5; Described chock plate handle 2 along its length on have the second spring groove, described second Returnning spring 1 is installed in described second spring groove, one end of described second Returnning spring 1 contacts on the inwall of described second spring groove, and the other end of described second Returnning spring 1 contacts on described air filter base 5.
Further again, described self-locking mechanism also comprises chock plate handle pressing plate 6, and described chock plate handle 2 is limited in described chute 52 by described chock plate handle pressing plate 6.
Further, described air filter base 5 is provided with the first spring stop 53 and the second spring stop 54, the other end of described first Returnning spring 4 contacts on described first spring stop 53; The other end of described second Returnning spring 1 contacts on described second spring stop 54.
