The upper/lower terminal of upper swivel nut 3 is spindle nose, and middle part is hexahedron.The center of upper swivel nut 3 is provided with screwed hole, and the lower end spindle nose of upper swivel nut 3 is provided with external screw thread.
The screwed hole size of upper swivel nut 3 is identical with the thread size of screw rod 6, and is left hand thread.
The upper end of lower swivel nut 4 is spindle nose, and bottom is hexahedron.Lower swivel nut 4 centers are provided with through hole, and the spindle nose of lower swivel nut 4 upper ends is provided with internal thread.External screw thread on dimension of inner screw thread on lower swivel nut 4 spindle noses and upper swivel nut 3 lower end spindle noses is measure-alike, and is right-handed thread.The spindle nose external diameter of lower swivel nut 4 upper ends is less than pallet 2 circular hole internal diameter 2 ~ 3mm.The height dimension of lower swivel nut 4 upper end spindle noses is greater than the gauge 1 ~ 2mm of pallet 2.
The corresponding connection of hexahedron of 1 inner hexagonal hole and upper swivel nut 3 of shaking the hand, and be arranged in the card of pallet 2.Upper swivel nut 3 lower end spindle noses are corresponding to be connected in the circular hole of pallet 2 with lower swivel nut 4 upper shaft head threads.The stage casing of screw rod 6 is threaded in the screwed hole of swivel nut 3, the afterbody polished rod section of screw rod 6 vertically under.Three claw hooks 5 are distributed on the below of pallet 2.The suspension ring hook end of claw hook 5 is hinged in Lu's word shape aperture of pallet 2, and the crotch end of claw hook 5 naturally droops.
Useful technique effect of the present invention is embodied in following several aspect:
1. use the present invention in the time of dismounting crankshaft belt pulley, belt pulley side is stressed evenly, and quick detachable, the belt pulley not damaged after dismounting is reusable;
2. to have volume little, easy and simple to handle, versatility is good in the present invention, reduces operating cost, improved maintenance efficiency, is ordinary maintenance personnel's good assistant.
