A generator set according to claim 2, wherein: the locking piece is a pin shaft I and a pin shaft II, inclined sections matched with inclined surfaces of the inclined parts of the button are respectively arranged on the pin shaft I and the pin shaft II, and when the button is driven to slide reciprocally, the inclined sections of the pin shaft I and the pin shaft II are driven by the inclined surfaces of the inclined parts to slide reciprocally.
4. A generator set as claimed in claim 3, wherein: the movable channel capable of allowing the locking piece to slide back and forth is arranged in the mounting seat along the transverse direction, the end faces at the two transverse ends of the movable channel are obliquely arranged, and the end faces, in contact with the inclined end faces of the movable channel, of the locking piece are obliquely arranged in the same way.
5. A generator set according to claim 4, wherein: the mounting seat is also provided with a guide hole, and the button slides in a single degree of freedom in a reciprocating manner on the mounting seat through the guide hole.
6. A generator set according to claim 5, wherein: a spring I is arranged between the pin shaft I and the pin shaft II, a spring II is arranged between the button and the mounting seat, and the spring I and the spring II are respectively used for providing reset elastic force for the reciprocating sliding of the locking piece and the button.
7. A generator set as claimed in claim 3, wherein: and the pin shafts I and II are respectively provided with an avoidance section, and the avoidance sections are used for avoiding the inclined parts of the buttons.
8. A generator set according to claim 7, wherein: the pull rod body is divided into a pull rod inner tube and a pull rod outer tube, the end part of the pull rod inner tube on the handle side is fixedly connected with the connecting part on the pull rod side on the connecting seat, the other end of the pull rod inner tube is fixedly connected with a tailstock arranged in the pull rod outer tube, and the pull rod inner tube can axially move in the pull rod outer tube and is limited through the tailstock.
9. A generator set according to claim 8, wherein: a plug is arranged below the tailstock in the outer tube of the pull rod, and the plug is clamped at the tail part of the outer tube of the pull rod; the plug is provided with a spring III at one side towards the tailstock, and the spring III is used for providing upward elasticity for the pull rod inner tube to pop out of the pull rod outer tube.
