Sealing the distal end of one kind of gun antifreeze

Providing the sealing of the distal end of one kind of antifreeze gun, ingenious and reliable mechanism; four kinds of innovative progress. Upper locking knob (10) is provided with a rivet hole of the new punch knurl (10b) facilitates preventing disengagement; newly provided with a groove (10a), to facilitate wetting of the finger on the lock button (10) also You can seize. Second, the cracking problem gun; conventional water gun sealing water retained in the gun body leads to the gun there freezing rupture; sealing the distal end of the present approach was completely solved; when the handle is released the reset lever, having equal to the pressure angle characteristics always equiangular spiral is also called a logarithmic spiral sealing plugs to drive the distal end of the card to ensure that no seal will seal ring moves forwardly out of the gun. Third, the color plate (7) is provided with a plurality of cam holes conducive to more color on. The fourth is the convex outer race ring inlet adapter card pitch, lead angle, the lead adapted to seal the internal torsional stresses and improved anti.
