Description

technical field

[0001] The invention belongs to leaking fluid equipment, in particular to a fluid leaking gun. Background technique

[0002] Gearboxes are widely used for speed change in vehicles, ships, and engineering equipment. Oil replacement is an important part of gearbox repair and maintenance. In order to replace the engine oil, the gearbox adopts the structure of setting an oil drain screw on the oil pan. When changing the oil, unscrew the oil drain screw first, drain the waste oil directly from the oil drain hole, and then add new oil from the filler port. Since the oil drain screw must be unscrewed every time the oil is changed, and then screwed on after the oil is drained, the thread of the oil drain hole of the oil pan is easily damaged if the oil is changed too many times or carelessly, resulting in damage to the oil pan, leaking, light If the oil pan needs to be replaced, the engine will be scrapped if it is heavy. The traditional gear box oil drain screw s...
