The invention provides a two cycle engine which effectively suppresses an intrusion of a combustion gas into a crank chamber. Further, the invention provides a two cycle engine tool provided with the two cycle engine mentioned above. An engine is provided with a cylinder having two scavenge air ports at different positions in a cylinder circumference direction, and scavenge air inflow ports communicating individually with these two scavenge air ports via a scavenge air passage, and a piston in which two scavenge air communication ports are formed at positions corresponding to the scavenge air inflow ports, and is structured to swirl the gas flowing into the piston from the cylinder through the scavenge air passage, in an upper portion of the internal space of the piston, and retains the gas in the upper portion of the internal space of the piston.

The invention relates to a scraper structure, which is generally comprised of a long handle for handgrip and a scraping section in its front. Basically, the scraping section of the scraper is comprised of a jaw plate, a blade, a fastener and a fastening button. The front end of the scraping section extends downward or forward to form a blade slot and has a jaw base at the bottom to connect to the blade slot. The jaw plate has identical shape to the clamp jaw in the front of the jaw base. The fastener and the fastening button are combined to provide tightening and enable the clamp jaw in the front of the jaw plate to exert great pressure onto the blade and achieve quick blade replacement and assembly. Further, the fastening button can exert more force by the front hand in grasping the handle and achieve powerful scraping.

The invention relates to a method for cleaning an insulating oil sample bottle and a utilized cleaning device. The insulating oil sample bottle cleaning method comprises the steps of (1) ultrasonic decontamination: before work, preheating water to a suitable temperature firstly, adding laundry powder, placing an oil sample bottle in a cleaning basket which is then placed in a cleaning tank, rotating the cleaning basket to enable the oil sample bottle to be filled with a cleaning solution, and starting a decontamination ultrasonic generator for the decontamination; and (2) ultrasonic rinse: opening a blowdown valve after the decontamination cleaning is finished, cleaning the cleaning tank appropriately after the cleaning solution is discharged completely, closing the valve, opening a water inlet valve, opening the ultrasonic generator, heating the water to a suitable temperature, placing the oil sample bottle into the water for rinse, and after the oil sample bottle is rinsed cleanly, taking the bottle out of a vessel and performing draining separation. The method for cleaning the insulating oil sample bottle and the utilized cleaning device have the advantages as follows: (1) the cleaning speed is high, the cleaning effect is good, the cleanliness is high, and the damage to the surface of a workpiece is prevented; (2) hands of a worker are not contacted with the cleaning solution, and deep holes, thin seams and hidden positions of the workpiece can also be cleaned up safely and reliably; and (3), the cleaning precision is high, and tiny stain particles can be cleaned powerfully.
