Hollow rotary shaft：It can be rotated in revolving joint and the excellent sealing between revolving joint, realization are high
Press the rotation docking of current；
Jointing clip：Play coaxial connection fixation hollow rotation axis and Hollow Transmission Shafts；
Turntable：For installing manual sealing adjusting mechanism, and disperse high pressure water flow, by driving the drive of motor, into
Row rotating jet cutting operation；
By turning pressure cap, the downward top pressure pressing sleeve of pressure cap, pressing sleeve lower face is pressed down against soft sealed packing（Soft seal is filled out
Material, is commonly called as pureed soft packing, is a kind of new airtight and watertight padding without asbestos synthesis of polymer material, and appearance such as clay shape has spy
Different plasticity）, soft sealed packing seals compression bar outer surface, avoids high pressure water from revealing herein；
Pressure pad lower surface is upward concave spherical structure, can improve the sealing effect to jet hole；
Pressing sleeve lower face is the up-small and down-big concave structure in cone, right so when being pressed down against soft sealed packing
The extruding force of soft sealed packing fully improves sealing effect towards compression bar.
Due to needing to bear the high pressure of high pressure water in turntable, this just needs sufficiently to be sealed, therefore in the first sealing
The first sealing structure being slidably matched with the first sealing adjusting block is set on case, adjusting block lower surface and first is sealed first
Guide groove inner wall sets the first corrosion protection gasket that cooperation is slidingly sealed with turntable inner bottom surface and guiding cheekn respectively, second
Set on seal box with the second second seals structure for being slidably matched of sealing adjusting block, in the second sealing adjusting block lower surface and
