Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution: disconnected internal thread extractor, including tool bit 1 with install at 1 outside handle of a knife 4 of tool bit, the side cross-section of tool bit 1 is the rhombus structure, and mounting groove 101 has all been seted up to the top of tool bit 1 and bottom inboard, and the inboard of two sets of mounting grooves 101 all is provided with sloping block 2, the inboard fixedly connected with inserted block 203 of sloping block 2, slot 102 has been seted up in the outside that the inside of tool bit 1 is located inserted block 203, horizontal fixedly connected with runs through the spacing traveller 202 of tool bit 1 is personally submitted to the right-hand member of inserted block 203.

Specifically, as shown in fig. 1-3, spacing slide opening 103 has been seted up in the outside that the inside of tool bit 1 is located spacing traveller 202, and spacing slide opening 103 and spacing traveller 202 are transition fit, the side cross-section of slot 102 and inserted block 203 all is protruding type structure, and the interior table wall of slot 102 laminates with the exterior wall of inserted block 203 each other, spacing slide opening 103 and spacing traveller 202's setting, the stability of sloping block 2 and tool bit 1 horizontal fixation has been promoted, the setting of slot 102 and inserted block 203 has simultaneously promoted sloping block 2 and tool bit 1 longitudinal fixation's stability, thereby when having reduced tool bit 1 and having rotated, sloping block 2 rocks the production of phenomenon.

Specifically, as shown in fig. 1-3, the equal fixedly connected with in preceding terminal surface and the rear end face middle part of tool bit 1 is horizontal distribution's degree of depth locating ruler 3, the outside fixedly connected with clutch block 201 of sloping block 2, preformed hole 401 has been seted up to the tail end inside of hilt 4, the setting of degree of depth locating ruler 3, can make the audio-visual tool bit 1 male degree of depth of learning of operating personnel, clutch block 201's setting, both the top of tool bit 1 of being convenient for, the contact friction between silk and the sloping block 2 in the broken can having promoted simultaneously, the setting of preformed hole 401 simultaneously, on the one hand, the outside rod of being convenient for runs through and supplementary rotation processing, on the other hand, be convenient for the holistic processing of putting of hanging of extractor.

The working principle is as follows: during the use, according to the internal diameter condition of disconnected internal thread, the inserted block 203 on the sloping block 2 of assigned size slides in the inside of slot 102, and slide spacing traveller 202 on the sloping block 2 in the inside of spacing slide opening 103, just accomplished the installation processing of sloping block 2 and tool bit 1, deepen tool bit 1 in the inside of disconnected internal thread, and through the tail end of external force hammering sword handle 4, and observe the length that tool bit 1 deepened through degree of depth locating rule 3, because the inflation effect of sloping block 2, disconnected internal thread can fix between two sets of sloping blocks 2, just can drive disconnected internal thread whole screw out pipeline interface when rotating sword handle 4, after disconnected internal thread takes out, outwards extract tool bit 1 from disconnected internal thread inside, two sets of sloping blocks 2 just can be atress drops on tool bit 1, just accomplished the processing of demolising after the extractor uses.

The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
