It rises and is located in groove.Protrusion is snapped onto groove, resistance when increasing cylinder rotation prevents cylinder convenient for fixing cylinder
Body skids, so that upper cover is easy to rotate and open.
Further, the cross section of groove is circle, and groove is opened up along the length direction of cylinder, and the upper end of groove is located at cylinder
Middle part, protrusion be hemispheric protrusion, protrusion recline with groove inner wall.Protrusion is arranged to it is hemi-spherical, convenient for protrusion be easy
It snaps onto groove, half flute profile protrusion and hemispherical groove increase the contact surface of cylinder and cylinder, so that cylinder is easier to lead to
Pedestal is crossed to fix.
Further, cylinder top is circumferentially arranged with anti-skid chequer.It is convenient for being not easy to skid when hand-held cylinder by setting anti-skid chequer,
It can prevent cylinder from falling from hand.
Further, bottom plate two sides are equipped with semicircle or rectangle snap ring.It, can be by operator's foot when needing to open upper cover
First half extend into snap ring, snap ring is stepped on by foot and is convenient for fixing bottom plate, is easier in this way using spanner rotation upper cover.
Further, bottom plate lower end surface is equipped with anti-skid chequer.It is stepped down on bottom plate using foot, passes through the anti-skid chequer energy of lower surface of base plate
Increase the frictional force of bottom plate and ground, convenient for opening upper cover.
