Gasoline engine starting relay and method of starting a gasoline engine

A small two-stroke or four-stroke gasoline engine starting relay comprises a housing (1), a power transfer end assembly (2), a power output end assembly (3), wherein the housing is provided with a device tube slot (4) which has holes on both sides, namely a power transfer end hole (5) and a power output end hole (6) respectively, and which is mated with the power transfer end assembly and the power output end assembly;

• a. the power transfer end assembly comprises a roller bearing (7) and a power transfer shaft (8), wherein the power transfer shaft which is sleeved with the roller bearing comprises a power connector (9), a transfer shaft seal axis (10) and a transfer shaft linkage shaft tube (11);
• the transfer shaft seal axis is provided in the power transfer end hole, with the power connector of the head end of the transfer shaft seal axis extending out of the device tube slot and exposed to the outside of the housing, the transfer shaft linkage shaft tube is provided in the device tube slot in the power transfer end hole, and the transfer shaft seal axis is sleeved with the roller bearing;
• b. the power output end assembly comprises a unidirectional roller bearing (12) and a power output shaft (13), wherein the power transfer shaft comprises a power output head (14), an output shaft seal axis (15), an output shaft linkage shaft (16) and an output end bearing (17);
• the output shaft seal axis is provided in the power end hole, with the power output head extending out of the head end of the output shaft seal axis and exposed to the outside of the housing from the power output end hole, and the output shaft seal axis is sleeved with the output end bearing, and the unidirectional roller bearing is sleeved on the output shaft linkage shaft;
• c. the output shaft linkage shaft of the power output end assembly is mated in the transfer shaft linkage shaft tube, and the unidirectional roller bearing is sandwiched between the lower portion of the inner wall of the body of the transfer shaft linkage shaft tube, with the power transfer end assembly (2) and the power output end assembly (3) connected as a whole.
