towards the right side, thereby driving the first ratchet 45, the first rotating shaft 43, the rotating plate 41 and the gas stove burner to rotate 10 degrees, the first spring 46 is stretched anticlockwise, when the first slide bar 48 is separated from the first slide bar 44, the first slide bar 44 will drive the first ratchet 47 to return to the left under the action of the first spring 46, at this time, under the action of the third spring 410, the first ratchet 47 will not drive the first ratchet 45 to rotate, so reciprocating for 6 times can drill 6 evenly spaced slots on the burner head of the gas cooker, and when the first slide bar 44 moves to the right, the shaped block 710 will move to the right, under the action of the eighth spring 711, the shaped block 710 will smoothly pass through the top of the second slide bar 71, and the distance of each movement of the shaped block 710 is the distance of one tooth at the top of the second slide bar 71, when the first slide bar 44 returns to the left, the second slide bar 71 will move to the left, the fifth spring 72 will be compressed, the second slide bar 71 will push the second block 73 forward, the sixth spring 74 will be compressed, when the second slide bar 71 is aligned with the second block 73 again, under the action of the sixth spring 74, the second latch 73 is snapped into the second slide bar 71 again, so that it cannot be reset to the right, and thus, reciprocating the first slide bar 44 can move the second slide bar 71 to the left by a distance of 6 teeth, and when the second slide bar 71 moves to the left, the second ratchet 76 is driven to move to the left, and under the action of the seventh spring 79, the second ratchet 76 does not drive the second ratchet 75 to rotate, and the second slide bar 71 moves to the left and is separated from the first special-shaped bar 81, and the second slide bar 71 moves to the left and also drives the first slide bar 85 to move to the left, and when the second slide bar 71 moves to the left by a distance of 6 teeth, the first slide bar 85 is located right above the second wedge 87, and then the connecting bar 42 moves upward and drives the first slide bar 85 to move upward, and the twelfth spring 86 is compressed, thereby driving the second latch 73 to move forward, and the second latch 73 no longer has the second slide bar 71, meanwhile, the first sliding rod 85 moves upwards to drive the special-shaped block 710 to move upwards, the special-shaped block 710 does not block the second sliding rod 71 any more, under the action of the fifth spring 72, the second sliding rod 71 and the second ratchet bar 76 can reset rightwards and drive the second ratchet 75, the first rotating shaft 43, the rotating plate 41 and the gas stove burner to rotate 60 degrees anticlockwise, after the second fixture block 73 moves forwards, the first special-shaped rod 81 can reset leftwards under the action of the tenth spring 82, the first special-shaped rod 81 can clamp the second fixture block 73 so as not to reset, after the second sliding rod 71 moves leftwards, the second sliding rod 71 can be separated from the second special-shaped rod 83, under the action of the compressed eleventh spring 84, the second special-shaped rod 83 can reset forwards, and then when the first sliding rod 85 drives the special-shaped block 710 to move upwards, the special-shaped block 710 can smoothly pass through the second special-shaped rod 83, and the second special-shaped block 83 can block 710 can be clamped, like this dysmorphism piece 710 and second fixture block 73 all can not block second slide bar 71, second slide bar 71 resets right and can push second dysmorphism pole 83 to the rear side, eleventh spring 84 is compressed, second slide bar 71 resets right and can also push first dysmorphism pole 81 right, tenth spring 82 is compressed, first dysmorphism pole 81 and second dysmorphism pole 83 no longer block second fixture block 73 and dysmorphism piece 710 respectively, second fixture block 73 and dysmorphism piece 710 can automatic re-setting, reciprocate just so can be automatic rotation 60
