Specific embodiment:
When user needs to dismantle sealing ring, it is necessary first to fixed oil pump position using frock, then user
Three-jaw disassembly mechanism is put in the top of oil pump again, with hand turn clockwise top short handle, now screw rod guide pillar start to revolve
Turning, linear bearing plays a part of guiding on screw rod guide pillar, prevents screw rod guide pillar from being shifted during motion, due to
External screw thread is provided with screw thread guide pillar so that is also and then moved with the intermeshing screw rod gland of screw rod guide pillar, due to screw rod
Gland is linked together by connection sheet and claw fix bar, therefore screw rod gland can only move up, screw rod gland
Mobile drive connection sheet movement so that claw fix bar around latch and/or bolt and/or rotate longitudinal center line
（Inner side）One lateral movement, claw fix bar bottom are shunk, then user estimate again claw head can be placed on the inside of sealing ring with
Afterwards, then by three-jaw mechanism put down so that claw head depth enters sealing ring inwall, because the arc-shaped boss on card movable block is by close
The extruding of seal ring inwall, spring, which is extruded, to be started to shrink at so that and the support on portable plate moves along the sliding space in groove, when
When claw head stop motion, the inwall of sealing ring reduces to portable plate extruding dynamics, and now spring will recover due to elasticity
Original position, so will extrude movable block, so that the arc cam on movable block is brought into close contact the interior of sealing ring
Wall, increase frictional force（Because movable block can freely stretch, so being adapted to the sealing ring of different hardness）, then user's another mistake
Hour hands rotate short handle so that screw rod gland moves downward, and hauls connection sheet and moves downward, so that claw fix bar bottom
Portion opens, the increase of claw head spacing, and the movable block of taper opens under leverage on the outside of claw head, increases movable block and sealing
The frictional force of ring inwall, because sealing ring is made up of the metal plate stamping part and inside and outside two layers of rubber coated of internal layer, so card
Pawl head can be in the rubber layer of embedding sealing ring inwall, and now sealing ring clamping is finally rotated length by three-jaw disassembly mechanism again with hand
Handle（Internal thread on three-jaw nigger is intermeshed with the external screw thread on screw rod guide pillar）And outwards pull out, three-jaw mechanism is just returned
Whole sealing ring is driven to move, most sealing ring pulls out at last.
It is described above, only specific embodiment of the present utility model, but the scope of protection of the utility model is not limited to
In this, any one skilled in the art can readily occur in change in the technical scope that the utility model discloses
Or replace, it should all cover within the scope of protection of the utility model.Therefore, the scope of protection of the utility model is with claim
Protection domain be defined.
