Abstract
The utility model is that a kind of small space internal thread hole aids in chasing bar, including ratchet carriage, neodymium iron boron cylindrical magnet and screw tap sleeve；Described screw tap sleeve be hollow cylinder, the inner upper end of cylinder and lower end into a ladder, and upper end internal diameter more than lower end internal diameter；Described ratchet carriage is hollow cylinder, cylinder is divided into two sections, outside epimere external diameter is more than hypomere external diameter, and the hypomere external diameter of described ratchet carriage is identical with the internal diameter of described screw tap sleeve inner upper end, and described ratchet carriage epimere external diameter is identical with the cylinder external diameter of described screw tap sleeve；The height of described neodymium iron boron cylindrical magnet is highly added the height of the column body upper end equal to described screw tap sleeve with described ratchet carriage hypomere.A kind of small space described in the utility model internal thread hole aids in chasing bar, easy to use, by combining screw tap and ratchet spanner, solves the small rare problem of space tapping internal thread.
Description
Technical field
The utility model is related to chasing bar field, more particularly to a kind of small space to aid in chasing bar with internal thread hole.
Background technology
During shell rim surrounding internal thread hole tapping, working space it is inadequate in the case of, it is impossible to conventional tapping method,
A kind of small space internal thread hole auxiliary chasing bar is designed, the convenient operation on casing completes in particular cases internal thread hole
Tapping problem.
The content of the invention
The utility model provides a kind of small space internal thread hole and aids in chasing bar, including ratchet carriage, neodymium iron boron circle
Post magnet and screw tap sleeve；
Described screw tap sleeve is hollow cylinder, and into a ladder, and the internal diameter of upper end is big for the inner upper end of cylinder and lower end
In the internal diameter of lower end；Described ratchet carriage is hollow cylinder, and cylinder is divided into two sections, and outside epimere external diameter is more than outside hypomere
Footpath, the hypomere external diameter of the described ratchet carriage ratchet carriage epimere identical, described with the internal diameter of described screw tap sleeve upper end
External diameter is identical with the cylinder external diameter of described screw tap sleeve；The height and described ratchet carriage of described neodymium iron boron cylindrical magnet
Hypomere is highly added the height of the column body upper end equal to described screw tap sleeve；
Described neodymium iron boron cylindrical magnet is placed on the ladder of described screw tap sleeve inner；Under described ratchet carriage
Section packs into described screw tap sleeve inner, and is pressed on described neodymium iron boron cylindrical magnet.
Further, the material of described ratchet carriage is copper.
Further, the material of described screw tap sleeve is manganese steel.
The beneficial effects of the utility model are：A kind of small space described in the utility model internal thread hole aids in tapping to fill
Put, it is easy to use, by combining screw tap and ratchet spanner, solve the small rare problem of space tapping internal thread.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Wherein：1- ratchet carriages；2- neodymium iron boron cylindrical magnets；3- screw tap sleeves.
Specific embodiment
It is described in detail referring to the drawings below with reference to embodiment of the present utility model.
A kind of small space internal thread hole aids in chasing bar, including ratchet carriage 1, neodymium iron boron cylindrical magnet 2 and screw tap
Sleeve 3；
Described screw tap sleeve 3 is hollow cylinder, and into a ladder, and the internal diameter of upper end is big for the inner upper end of cylinder and lower end
In the internal diameter of lower end；Described ratchet carriage 1 is hollow cylinder, and cylinder is divided into two sections, and outside epimere external diameter is more than hypomere
External diameter, the hypomere external diameter of described ratchet carriage 1 ratchet carriage 1 identical, described with the internal diameter of the described upper end of screw tap sleeve 3
Epimere external diameter is identical with the cylinder external diameter of described screw tap sleeve 3；The height of described neodymium iron boron cylindrical magnet 2 and described spine
The hypomere of wheel sleeve 1 is highly added the height of the column body upper end equal to described screw tap sleeve 3；
On the ladder that described neodymium iron boron cylindrical magnet 2 is placed in inside described screw tap sleeve 3；Described ratchet carriage 1
Hypomere pack into inside described screw tap sleeve 3, and be pressed on described neodymium iron boron cylindrical magnet 2.
Further, the material of described ratchet carriage 1 is copper.
Further, the material of described screw tap sleeve 3 is manganese steel.
When using, 3 sets of screw tap sleeve screw tap, ratchet spanner is enclosed within ratchet carriage 1, by rotating ratchet wrench, band
Move described a kind of small space internal thread hole and aid in chasing bar, then drive screw tap to attack the shell rim in small space
Silk.
The above is only preferred embodiment of the present utility model, it is noted that for the common skill of the art
For art personnel, on the premise of the utility model principle is not departed from, some improvements and modifications can also be made, these improve and
Retouching also should be regarded as protection domain of the present utility model.
