A kind of bolt practice column
Technical field
The present invention relates to technical field of automobile maintenance more particularly to a kind of bolt to practice column.
Background technique
The use of automotive service set and the dismounting of bolt are automobile machine maintenance introduction basic training, are taught in most of automobile occupations
It in educating, uses to reinforce student to the familiar of tool and the specification of bolt fastening is practiced, school can will be a variety of different
Bolt is placed in one big plane, and student is allowed to practice the assurance of the selection of bolt, dismounting and torsion on it, in practice,
When using pulling hand-tighten bolts, since the protrusion of other bolts has blocked the rotation of spanner, so that stubborn process is not smooth, or even meeting
Hand is hurt, the raising of learner standard operation level itself is unfavorable for, therefore, solves the problems, such as that this just shows very necessary
?.
Summary of the invention
In view of the deficiencies of the prior art, the present invention provides a kind of bolts to practice column, solves the bolt twisted in big plane
When the problem of will cause hand injuries, the present invention is adopted the following technical scheme that in order to solve the technical problem including fixed plate, fixed
Plate is equipped with the jack of 2 row of at least 2 column, and the quantity of jack determines according to actual needs, and jack is through the front end of fixed plate with after
End, the front and rear end of fixed plate are provided with practice column, and the quantity for practicing column is identical as the columns of jack, practices a side of column
Telescopic rod is connected on face, the quantity of telescopic rod and the line number of jack are identical, telescopic rod longitudinal arrangement, and the other end of telescopic rod connects
It is connected to inserted link, inserted link cross-sectional diameter is less than the diameter of jack, practices on column and is connected with the opposed one side in telescopic rod side
At least 2 column threaded holes are equipped with, are equipped with bolt on threaded hole, bolt includes: outer-hexagonal bolt, hexagon socket head cap screw, outer plum blossom
The difference bolt such as stake, interior quincuncial pile, and various bolt random orderings arrange, and can change bolt type or position according to actual needs.
Further improvement lies in that: jack bosom position is equipped with detachable magnet, and inserted link is connected another with telescopic rod
The internal magnet that is equipped in end is inserted in inside jack by attracting each other between magnet so that inserted link is stable.
Further improvement lies in that: the left end of fixed plate and right end are equipped with detachable practice board, and 2 practice boards are equipped with 2
Column threaded hole, threaded hole at least 2 rows increase practice amount, student are facilitated to improve profile by increasing practice board.
Further improvement lies in that: the half of practice board length is less than the sum of telescopic rod and the length of inserted link, and practice two sides are practiced
It is time saving and energy saving it is not necessary that column pull-out will be practiced when practising the bolt on column.
The beneficial effects of the present invention are: after inserted link is injected the jack in fixed plate, by the flexible of telescopic rod, so that practicing
Column is practised freely to be moved forward or rearward in fixed plate front or behind, it, will when needing to practice the bolt on some practice column
This practice column pull out other practice columns where plane, when avoiding practice, because other bolts protrusion caused by hand
Injury, is conducive to the raising of learner standard operation level itself.

Specific embodiment
In order to deepen the understanding of the present invention, the present invention is further described below in conjunction with embodiment, the present embodiment
For explaining only the invention, it is not intended to limit the scope of the present invention..
Show picture 1-4, present embodiments provide a kind of bolt practice column, including fixed plate 1, fixed plate 1 are equipped with 4 column 3
Capable jack 2, jack 2 run through the front and rear end of fixed plate 1, and the front and rear end of fixed plate 1 is provided with 4 practice columns 3, practice
It practises and is connected with 3 telescopic rods, 4,34 longitudinal arrangements of telescopic rod on a side of column 3, the other end of telescopic rod 4 is connected with slotting
Bar 5,5 cross-sectional diameter of inserted link be less than jack 2 diameter, 2 bosom position of jack be equipped with detachable magnet 8, inserted link 5 with stretch
Be equipped with magnet 8 inside the connected other end of contracting bar 4, practice on column 3 be connected with the opposed one side in 4 side of telescopic rod and be equipped with
2 column threaded holes 6, threaded hole 6 are equipped with 6 different types of bolts 7, when needing to practice, different types of bolt 7 are placed on
On threaded hole 6, then by the reeve jack 2 of inserted link 5, so that practice column 3 is individually positioned in 1 front and back of fixed plate, practice some
When fixed plate 1, practice column 3 is pulled forward or afterwards, so that practice column 3 is forward or rear is mobile, so that this practice column 3 and other white silks
Habit column 3 in the same plane, can not practiced at this time, and the left end of fixed plate 1 and right end are equipped with detachable practice board 9,2
Practice board 9 is equipped with 2 column, 3 row threaded hole 6, and the half of 9 length of practice board is less than the sum of the length of telescopic rod 4 and inserted link 5.
