Fig. 1 show the utility model structure diagram, and the utility model is a kind of pin removal, including hammer 1, pull rod 2,
Nut 3, screw special 4.
There is boss in described 2 one end of pull rod, which not only can prevent hammer 1 from being slipped from pull rod 2, while is also to be used for
Hammer 1 is born to hit.The other end of pull rod 2 has one section of external screw thread, can be spun together with the internal thread of nut 3.Worn on pull rod 2
There is hammer 1, hammer 1 can be free to slide on pull rod 2.
Fig. 2 show 3 sectional view of nut, its external cylindrical surface carries out annular knurl processing, easy to manual rotation nut 3, in nut 3
Screw thread is screwed with 2 external screw thread of pull rod, and other two stepped hole is used for installing screw special 4.
Fig. 3 show 4 structure diagram of screw special, and numeral, numeral and pin tail are carved with the end face on 4 head of screw special
Portion's internal thread is in the same size, and the external cylindrical surface on 4 head of screw special carries out annular knurl processing, easy to rotate screw special 4.Special spiral shell
Nail 4 has two sections of different nominal diameter external screw threads, the big external screw thread of nominal diameter and the end at 1 non-impact end of hammer on screw special 4
Tapped blind hole coordinates at face, the small external screw thread of nominal diameter and pin afterbody screw-internal thread fit on screw special 4.
Fig. 4 show 1 sectional view of hammer, there is a through hole among hammer 1, enables hammer 1 free to slide on pull rod 2,
The endface at 1 non-impact end of hammer is distributed multiple identical tapped blind holes, the endface tapped blind hole at 1 non-impact end of hammer with specially
Coordinated with the big external screw thread of nominal diameter on screw 4.
When the utility model is used, according to pin afterbody internal thread size, corresponding screw special is unloaded from hammer 1
4, screw special 4 is installed on 2 one end of pull rod, and tighten nut 3, screw special 4 is fixed on pull rod 2, then by special spiral shell
Nominal diameter is small on nail 4 screws into pin afterbody internal thread, and hammer 1 then is moved on to pull rod 2 with externally threaded
At one end, hammer 1 is firmly hit, be repeated several times, pin is extracted, special spiral shell is unloaded from pin to the other end of pull rod 2
Nail 4, screw special 4 is screwed in the endface tapped blind hole at 1 non-impact end of hammer again.
The utility model is not limited to the above embodiment, in the case of without departing substantially from the utility model in essence content, ability
Any deformation, improvement, the replacement that field technique personnel are contemplated that each fall within the scope of the present invention.
