Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described:
See Fig. 1, Fig. 2, Fig. 3 and Fig. 4.
The smooth shaft like members extracting tool of the utility model one embodiment, comprise sleeve 1, base 2, collet 3, cone bar 5 and connecting rod 8, described base 2 is fixed in the front end inner chamber of sleeve 1, the rear end face of described base 2 has groove 21, the sidewall of groove 21 is provided with internal thread 211, the diapire of groove 21 has draw-in groove 212, described collet 3 is connected in draw-in groove 212 with its head, described cone bar 5 stretches in sleeve 1 from the rear end of sleeve 1, and cone bar 5 coordinates with sleeve 1 activity, the front end face of described cone bar 5 is provided with boss 51, the outer peripheral face of boss 51 is provided with the external screw thread 511 matched with the internal thread 211 on the sidewall of groove 21, the front end face of boss 51 has the taper type groove 512 for Compress Spring chuck 3, the front end of described connecting rod 8 is connected to the rear end of cone bar 5, the front end face of described base 2 has the through hole 22 leading to draw-in groove 212, pass through for smooth shaft like members to stretch in collet 3.
In the present embodiment, sleeve 1, base 2, cone bar 5 and the profile of connecting rod 8 are cylindrical, boss 51 is cylindrical, the inner chamber of groove 21 is also cylindrical accordingly, and described sleeve 1, base 2, collet 3, cone bar 5, connecting rod 8, boss 51, groove 21 and through hole 22 coaxial line.
In the present embodiment, described sleeve 1 overcoat has sheath 4.The material of sheath 4 can select flexible plastic or pvc pipe, and when dismantling smooth shaft like members, sleeve 1 may collide the inner surface of deep-hole parts, and sheath 4 then can prevent the inner surface damaging deep-hole parts because of collision.
In the present embodiment, the rear end face of described sleeve 1 has the notch 11 for snapping in spanner.Notch 11 is used in fixed muffle 1 when being rotatably connected bar 8, and concrete operations are stuck in by spanner in notch 11, blocks sleeve 1 by spanner.
In the present embodiment, the rear end of described connecting rod 8 is provided with handle 10.Arranging handle 10 can handled easily, saves strength.In order to enable handle 10 disassemble when not needing, be threaded in the rear end of described connecting rod 8 stop nut 9, and the lateral surface of described stop nut 9 has the first screwed hole 91, is then connected in the first screwed hole 91 by the threaded one end of handle 10.
In the present embodiment, on described connecting rod 8, slip cap is equipped with collision block 7, and collision block 7 is between cone bar 5 and stop nut 9.When using the utility model dismounting smooth shaft like members, clash into stop nut 9 with collision block 7, thus inertia can be utilized smooth shaft like members to be extracted, greatly reduce working strength.
