[Prior Art] According to the 'first known about the portable bearing extractor, as shown in Figure 5, #includes - fixed axle base 1, the central axis is miscellaneous - the misaligned screw 2 for shaft shifting, fixed The outer diameter of the outer diameter is three-ply rod 3, and the bottom end of the rod 3 is turned into a fishing claw, which is arranged on the bottom side of the circular diameter of the bearing to be disassembled (not shown). Because of the lack of effective positioning of the above three fishing claws, the bearing disassembly operation process, the operator must hold the other hand ring to assist the three pull rods 3 kiss ^ ^ 3AR heart clip difficult to undertake _ fine, borrowed for the lion snail The axial axis of the ageing operation forces the central axis of the bearing to be dismantled (not shown), and the redness of the bearing is completed. The entire operation process is not stable, and the efficiency of disassembly is not satisfactory. The creators of this case have been working hard to study and improve through years of work experience in production and customs-related products, and they have been transferred to the world with a very significant value. [New content] That is, the main purpose of this creation is to provide a simple structure for the improvement of the bearing extractor, and to provide the positioning reference for the shaft reading operation, and the disassembly and disassembly efficiency of the social lifting bearing: The present invention - a simple type of bearing extractor improved structure, comprising a fixed shaft seat, the central axis of which is pivoted - for the top of the shaft to move, the gamma axis is forced to disassemble the central axis of the bearing; The outer diameter of the shaft seat surrounds the '峨 line side _ pivot with a plurality of pull rods, and the end of the cup is taken from the Wei _ turn into a - hook claw portion, and the bottom surface of the bottom is M335589; The central axis of the fixed fixed shaft seat on the pivotal side of the pull rod shaft is respectively symmetrically obliquely recessed to form a resisting inclined surface, and the thrusting screw and the opposite side of the resisting inclined surface are pivoted to a limit for the central axis shifting adjustment manner. The bottom side of the outer diameter of the nut of the limiting nut is configured as an abutting taper portion opposite to the beveling surface of the resisting nut, and the radial locking of the hook portion is obtained by pressing the abutting taper shaft to firmly resist the inclined surface Limit, according to which the smooth shaft movement of the push screw is removed With the central axis. The simplified bearing extractor has a modified structure, wherein a central hollow axis of the fixed shaft seat is convex, and an inner diameter of the hollow neck is provided with an internal screw corresponding to the push screw, and the hollow neck The outer diameter of the φ has a thread corresponding to the screw hole in the corresponding limit nut. The simple bearing extractor has a fine structure, wherein the outer diameter of the top side of the limit nut is set as a coarse-twisted twist ring. / [Implementation] In order to enable the reviewer to gain a deeper understanding and recognition of the purpose, features and effects of this creation, a preferred embodiment is illustrated with a schematic description of the following. As shown in Fig. 1 and Fig. 2, the present invention provides a simple bearing extractor improved structure, which comprises: a fixed shaft seat 一, a push screw 20, a three pull rod 30 and a limit nut 40; The central axis of the shaft seat ίο is provided with a hollow neck η, and the inner diameter of the hollow neck portion is provided with an internal thread 11 Α 'the outer diameter of the hollow neck 1 则 is provided with an external thread 11 Β; The central axis of the shaft is cut to the opposite angles, and the three pivoting lugs 12 are respectively extended. The pivoting lugs 12 have a receiving groove 121 in the middle thereof, and the two end faces are symmetrically recessed to extend through the pivoting hole. The pushing screw 20 is axially screwed into the inner thread 11 of the hollow neck, and has a driving head 21 for the hand tool to be operated at the top end, and the pushing end 22 is at the bottom end. By axial axial shift adjustment, the central axis 51 of the bearing 50 is to be disassembled (see Figure 3). 4 M335589 The extraction rod 30 is generally a J-shaped body, and the top end thereof is formed as a shaft pivot portion 31, and the end faces of the flat sides of the flat jaws are provided with a pivot shaft corresponding to the pivot hole 122 of the pivoting lug 12. The hole 311, the 俾 is matched with a shaft pin 311 Α, and the locating slot 121 is disposed in the middle of the pivoting lug 12; the center of the fixed fixed shaft base 10 on the top side of the shaft pivot portion 31 is symmetrical obliquely The bottom surface of the pullout rod 312 is turned into a hook portion 32, so as to be hooked to the bottom end surface 52 of the circular shaft of the bearing 5 to be disassembled (as shown in FIGS. 3 and 4); The nut 4 has a tapered shape, and an axial inner diameter is provided with an internal thread 41 for the relative axial direction. The screw is 11 丨 outside the hollow neck 1 Β; One of the coarse-grained twisting ring 42 is arranged to be rotated by hand; the bottom side of the outer diameter of the outer diameter is set to an inclined cone portion 43 with respect to the resisting inclined surface 312. The portion 43 axially moves against the inclined surface 312 to obtain the radial stop restriction of the hook portion; The operation and use situation is as shown in Figures 2 and 4; firstly, as in the conventional bearing dismounting step, the hook portion 32 on the bottom side of the end of the three pull-out lever 30 is relatively hooked on a bearing to be disassembled. The bottom end face of the circular diameter is smashed, and the jacking screw 20 is rotated so that the pushing portion 22 of the bottom end thereof is axially displaced downward to adjust against the central shaft 51; at this time, in order to prevent the claw portion 32 on the bottom side of the end of the three pulling rod 30 When the external swaying occurs, the twisting ring 42 of the limit nut 40 is rotated, so that the axial internal thread 41 of the limiting nut 4 is relatively screwed to the hollow neck 11 The screw 11 is adjusted downward and the shaft is moved downward. During the process, the top end of the outer end of the outer end of the outer end of the outer end of the outer end of the outer end of the outer end of the outer end of the outer end of the outer end of the outer end of the outer end of the outer end of the outer end of the outer end of the outer end of the outer end Since the resisting inclined surface 312 is higher than the position of the pivoting hole 122 of the pulling 3G and the fixed shaft seat 1G, when the pressing taper portion 43 and the resisting inclined surface 312 are relatively pressed against each other, the hook portion 32 is radially obtained. Stop limit (shown in Figure 4); Finally, as the push screw 2 is rotated, the push end 22 of the bottom end is rotated The continuation of the downward shaft axially forced central shaft 51 is accompanied by the simultaneous upward miscible movement of the claw portion 32 of the bearing 5 〇 rounded bottom end surface 52, so that the bearing 50 is stably removed from the central shaft 51 thereof. .
