Abstract
The invention discloses a bolt which comprises a bolt body, wherein the bolt body is formed by connecting a bolt head and a screw; the bolt head is flat; an eccentric hole is arranged on the bolt head; the section of the bolt head is circular; and a plurality of bulges are formed on the front surface and the back surface of the bolt head. The bolt has the beneficial effects that since the bolt head is flat and the eccentric hole is arranged in the bolt head, the bolt can be directly screwed up or screwed off with hands when in use; and when applied to some precise mechanisms, the bolt can be screwed up in a way that a cylindrical roller is inserted into the eccentric hole and then rotated. The bolt is easy to operate and time-saving; and the bolt can be screwed up or screw off without different types of screwdrivers, thereby reducing the burden of people.
Description
Technical field
The present invention relates to a kind of bolt, especially a kind of bolt that needn't use screw-driver to tighten or to turn on belongs to the device technology field that fastening or fixed component or machine parts are used.
Background technique
Bolt is by bolt head and screw rod (having externally threaded cylindrical body) one type of fastening piece dimerous, is used to be fastenedly connected two machinery parts that have through hole.This Connecting format claims that bolt connects, and it is to belong to removably connect that bolt connects.Existing bolt will be used screw-driver in use usually, when bolt need be tightened or turn on, need hole with screw-driver inserting bolt head in, the rotary screw cutter is operated lengthy and tedious then; In addition, need prepare different screw-drivers, carry inconvenience for the bolt of different model.
Summary of the invention
Technical problem to above-mentioned existence the objective of the invention is: proposed a kind of bolt that needn't use screw-driver to tighten or to turn on.
Technical solution of the present invention is achieved in that a kind of bolt, comprises bolt body, and said bolt body is formed by connecting bolt head and screw rod, and said bolt head is flat; Have eccentric opening on the said bolt head.
Preferably, the cross section of said bolt head is rounded.
Preferably, be equipped with a plurality of convexities on the positive and negative surface of said bolt head.
Because the utilization of technique scheme, the present invention compared with prior art has advantage:
Bolt of the present invention; Because bolt head is flat; Have eccentric opening on the bolt head, directly can bolt of the present invention tightened or turn on during use, if when bolt of the present invention is used for some precision optical machineries and need steps up with hand; Can use a cylinder rod, be inserted in the eccentric opening rotation and get final product.Bolt of the present invention, easy and simple to handle, save time, needn't carry the screw-driver of different model it is tightened or turns on, alleviated people's burden.
Description of drawings
Below in conjunction with accompanying drawing technological scheme of the present invention is described further:
Accompanying drawing 1 is the stereogram of bolt of the present invention;
Accompanying drawing 2 is the side view of bolt of the present invention;
Wherein: 1, bolt head; 2, screw rod; 3, eccentric opening; 4, convexity.
Embodiment
Below in conjunction with accompanying drawing the present invention is described.
Like accompanying drawing 1, the of the present invention a kind of bolt shown in 2, comprise bolt body, said bolt body is formed by connecting bolt head 1 and screw rod 2, and said bolt head 1 is flat; Have eccentric opening 3 on the said bolt head 1; The cross section of said bolt head 1 is rounded; Be equipped with a plurality of protruding 4 on the positive and negative surface of said bolt head 1.During use, needn't carry the screw-driver of different model and tighten or turn on bolt of the present invention, directly can it tightened or turn on hand; The convexity 4 on the positive and negative surface of bolt head 1 can strengthen frictional force, bolt more of the present invention is tightened or is turned on, if use it in the time of need stepping up in some precision optical machineries; Can use a cylinder rod; Be inserted in the eccentric opening 3 rotation and get final product, easy and simple to handle, save time.
The foregoing description only is explanation technical conceive of the present invention and characteristics; Its purpose is to let the personage that is familiar with this technology can understand content of the present invention and implements; Can not limit protection scope of the present invention with this; All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
