New description: [New technical field] This creation is related to the ring machine removal tool, in more detail, especially an improved structure of the extractor. [Prior Art] It is known that the ring-shaped parts such as gears, pulleys, and bearings are often required to be assisted by a puller to assist in the removal of the self-fixed shaft. The pull-up 匕 3 has a solid-seat seat. Fixing the outer diameter of the shaft seat and concentrically dragging a plurality of cantilever arms having a claw portion on the bottom side of the end, and the center sleeve frame is provided with an axially movable pushing screw ' _ claw portion is provided around the hook to be disassembled The bottom side of the circular mechanism is forced by the jacking screw; because the cantilever lacks effective clamping position, the operator must hold the supporting claw concentrically on the bottom side of the circular mechanism, and the operation is not stable. The efficiency of disassembly is not ideal. • For this reason, the creator of this case has been researching and improving through the years of experience in producing similar products, and finally has a practical creation. [New content] That is, the main purpose of this creation is to provide an improved structure of the extractor, which provides stable operation of the ring-shaped parts such as gears, pulleys, and bearings, and greatly improves the efficiency of disassembly and application. The edge is 'an improved structure of the extractor according to the present invention, which comprises: a first limit seat' having an axial end recessed with a central screw hole penetrating through the top and bottom, and a circumferential side and a predetermined spacing correspondingly convex The plurality of pairs of pivoting lugs and 3 M415034 «the first end of the seat 10 is axially recessed with a central screw hole u' extending through the top of the top and its circumferential side and extending at an angular interval of 12G degrees Forming three pairs of sticking lugs 12, the opposite end sides of the pivoting lugs 12 are recessed-pivoting holes 12, and each of the pair of pivoting lugs 12 simultaneously forms a receiving groove 13; Having an external thread 21, the twisting wire is screwed to the first-center screw hole n of the first-limit seat 1G by means of a helical up-and-down axis shift adjustment, and the top end thereof has a driving head 22 for pulling and rotating operation, the bottom of which The outer diameter of the end is contracted to form a shaft pivot portion 23, the axial direction of which extends through the recess - the second central screw hole 24, the bottom side of the driving head 22 is axially and screwed and pivoted - the limit nut 25; The end face of the second limiting seat 30 is recessed and provided with a second central hole 3 through the top and bottom. The whole screw is pivoted, and the pivot portion 23 of the bottom end of the 2G is pivoted for the same Step axis shift; its circumferential ventral side and extending at a circular arc angular interval of 120 degrees respectively. The opposite end sides of the three pairs of pivoting lugs 32' grafting lobes 32 are recessed with a pole 321, each of which A plurality of receiving slots 33 are formed in the middle of the pair of pivoting lugs 32. The receiving slots 33 are pivotally coupled to a crank 34. The cranks are extended in a shape, and the front and rear ends respectively have a pivot hole 341 and a pivot. The hole 342, wherein the pivot hole 341 is connected to the pivot hole 321 by a shaft pin 341A; the movable clamp arm 40 is a long plate, one end of which is a pivot end 41' and has a pivotal connection Hole 411 '俾 for a shaft pin 412 string group pivot 5
