Bolt exercise post
Technical Field
The invention relates to the technical field of automobile maintenance, in particular to a bolt exercise column.
Background
The use of auto repair tools and the dismouting of bolt are the basic merit of car machine repair entry, in the middle of most automobile vocational education, in order to strengthen the student to the familiar use of instrument and to the standard exercise of bolt-up, the school can place various different bolts on a big plane, let the student practice the chooseing for use of bolt on it, the assurance of dismouting and torsion, in practice, when using the spanner to twist bolt, because the arch of other bolts has blocked the rotation of spanner, make the process of twisting unsmooth, can injure the hand even, be unfavorable for learner's own standard operation level's improvement, consequently, it is just necessary to solve this problem apparent.
Disclosure of Invention
Aiming at the defects of the prior art, the invention provides a bolt exercise column, which solves the problem of hand injury caused by screwing a bolt on a plane, and adopts the following technical scheme for solving the technical problem: including the fixed plate, be equipped with 2 at least jacks that are listed as 2 lines on the fixed plate, the quantity of jack is confirmed according to the actual demand, the jack runs through the front end and the rear end of fixed plate, the front end and the rear end of fixed plate all are furnished with the exercise post, the quantity of exercise post is the same with the line number of jack, be connected with the telescopic link on the side of exercise post, the quantity of telescopic link is the same with the line number of jack, telescopic link longitudinal arrangement, the other end of telescopic link is connected with the inserted bar, inserted bar cross section diameter is less than the diameter of jack, be equipped with 2 at least screw holes on the exercise post in the face of being connected with the opposite of telescopic link side, all be: different bolts such as outer hexagon bolt, interior hexagon bolt, outer quincuncial pile, interior quincuncial pile, and various bolts are arranged out of order, can change bolt kind or position according to actual demand.
The further improvement lies in that: the inside intermediate position of jack is equipped with dismantlement formula magnet, and the other end that the inserted bar links to each other with the telescopic link is inside to be equipped with magnet, through the inter attraction between the magnet for the stable inserting inside the jack of inserted bar.
The further improvement lies in that: the left end and the right-hand member of fixed plate all are equipped with dismantlement formula exercise board, are equipped with 2 rows of screw holes on 2 exercise boards, and the screw hole has 2 lines at least, through increasing the exercise board, has increased the exercise volume, makes things convenient for the student to improve individual ability.
The further improvement lies in that: half of the length of the exercise board is smaller than the sum of the length of the telescopic rod and the length of the inserting rod, so that the exercise columns do not need to be pulled out when the bolts on the exercise columns on the two sides are exercised, and time and labor are saved.
The invention has the beneficial effects that: insert the inserted bar behind the jack on the fixed plate, through the flexible of telescopic link for the exercise post is in fixed plate the place ahead or the free forward or backward movement in rear, when the bolt on a certain exercise post of needs exercise, pull out this exercise post other exercise post place planes can, when having avoided the exercise, because of the protrusion of other bolts causes the injury to the hand, is favorable to the improvement of learner's the normal operation level itself.

Detailed Description
In order to further understand the present invention, the following detailed description will be made with reference to the following examples, which are only used for explaining the present invention and are not to be construed as limiting the scope of the present invention.
As shown in fig. 1-4, the embodiment provides a bolt exercise column, which comprises a fixing plate 1, wherein 4 rows of 3 rows of jacks 2 are arranged on the fixing plate 1, the jacks 2 penetrate through the front end and the rear end of the fixing plate 1, 4 exercise columns 3 are respectively arranged at the front end and the rear end of the fixing plate 1, 3 telescopic rods 4 are connected to one side surface of each exercise column 3, the 3 telescopic rods 4 are longitudinally arranged, an inserting rod 5 is connected to the other end of each telescopic rod 4, the diameter of the cross section of each inserting rod 5 is smaller than that of each jack 2, a detachable magnet 8 is arranged in the middle position inside each jack 2, a magnet 10 is arranged inside the other end of each inserting rod 5 connected with each telescopic rod 4, 2 rows of threaded holes 6 are arranged on one side surface of each exercise column 3 opposite to the side surface connected with each telescopic rod 4, 6 different types of bolts 7 are arranged on the threaded holes 6, when, inject the inserted bar 5 into jack 2 again, make exercise post 3 place at 1 front and back of fixed plate respectively, when practicing a certain fixed plate 1, pull exercise post 3 forward or back, make exercise post 3 forward or rear remove, make this exercise post 3 not on same plane with other exercise posts 3, can practice this moment, the left end and the right-hand member of fixed plate 1 all are equipped with dismantlement formula exercise board 9, be equipped with 2 and be listed as 3 line screw holes 6 on 2 exercise boards 9, half of exercise board 9 length is less than the length sum of telescopic link 4 and inserted bar 5.
