Description
Technical field
The utility model relates to a kind of fastening piece, and more particularly, it relates to a kind of convenient bolt.
Background technique
Bolt, by head and screw rod (with an externally threaded cylindrical body) class fastening piece dimerous, its structure is simple, for connecting two parts with through hole.Divide by nose shape: have hexagonal, round end, countersunk head etc.This bolt needs the suitable spanner of extra size or other instruments to tighten usually.
During routine use, although common bolt has the bar portion with substantially invariable diameter, and the guided portion of minor diameter or taper is equipped with in front end, inserting in box thread component to prevent tilt bolt and kill, but being tightened by instrument, during operation, sensitivity has and necessarily weakens, can not ensure that bolt is screwed in box thread component smoothly very well, especially longer bolt is easy to deviation, needs repeatable operation, wastes time and energy.
Model utility content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of convenient bolt being easy to be screwed into.
For achieving the above object, the utility model provides following technological scheme:
A kind of convenient bolt, the first screw rod comprising bolt head and be fixedly connected with bolt head, also comprise the second screw rod, projection is provided with bottom described first screw rod, described second screw tip is provided with the groove that to match with projection, projection and groove are equipped with hinging shaft, and described second screw tip is provided with limiting stopper.
Preferably, described limiting stopper is arranged at hinging shaft side, and when the first screw rod and the second screw rod are in same axis, limiting stopper and the first screw rod are conflicted.
Preferably, described bolt head is provided with cross recess.
Preferably, described first spiro rod length is the twice of the second screw rod.
Compared with prior art, the beneficial effects of the utility model are: the first screw rod that a kind of convenient bolt not only comprises bolt head and is fixedly connected with bolt head, also comprise the second screw rod, projection is provided with bottom described first screw rod, described second screw tip is provided with the groove that to match with projection, projection and groove are equipped with hinging shaft, pass through projection, the cooperation of groove and hinging shaft, make relative first bolt rotary of the second screw rod energy, make when being screwed into bolt, can without instrument, second screw rod is screwed in box thread component as dwang by the first bolt, directly be screwed into by hand, considerably increase performance accuracy, make bolt can more easily in box thread component, deviation is less likely to occur, a part of second screw rod is screwed into after in box thread component, again the first screws is in same axis to the second screw rod, limiting stopper and the first bolt are conflicted, first bolt and the second screw rod vertical direction are fixed, and agree with box thread component due to a second screw rod part, so the first bolt can easily be screwed in box thread component, solve bolt to be difficult to be screwed into the problem in box thread component smoothly, provide a kind of bolt being easy to be screwed into.

Embodiment
With reference to accompanying drawing, a kind of convenient screw embodiment of the utility model is described in further details.
Referring to figs. 1 through Fig. 5, a kind of convenient bolt, the first screw rod 2 comprising bolt head 1 and be fixedly connected with bolt head 1, also comprise the second screw rod 3, projection 4 is provided with bottom described first screw rod 2, described second screw rod 3 top is provided with the groove 5 that to match with projection 4, projection 4 and groove 5 closely cooperate, first screw rod 2 can fully drive the second screw rod 3 to rotate, projection 4 and groove 5 are equipped with hinging shaft 6, by projection 4, the cooperation of groove 5 and hinging shaft 6, second screw rod 3 can be rotated relative to the first screw rod 2, make when being screwed into bolt, can without instrument, second screw rod 3 is screwed in box thread component as dwang by the first bolt, directly be screwed into by hand, considerably increase performance accuracy, make bolt can more easily in box thread component, deviation is less likely to occur, a part of second screw rod 3 is screwed into after in box thread component, again the first screws is in same axis to the second screw rod 3, limiting stopper 7 and the first bolt are conflicted, because described limiting stopper 7 is arranged at hinging shaft 6 side, do not affect the second screw rod 3 to be hinged the rotation of axle 6 opposite side, and the first bolt and the second screw rod 3 vertical direction are fixed, and agree with box thread component due to second screw rod 3 part, so the first bolt can easily be screwed in box thread component, solve bolt to be difficult to be screwed into the problem in box thread component smoothly, provide a kind of bolt being easy to be screwed into.
In the present embodiment, described bolt head 1 is provided with cross recess 8, bolt is made to coordinate more instrument, and described first screw rod 2 length is the twice of the second screw rod 3, the hinged place of the first bolt and the second screw rod 3 is made to be in total length 1/3rd place, both ensured that hinged place can not be in outside box thread component, and had the first longer screw rod 2 allow when being manually screwed into lighter.
The above is only preferred implementation of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technological schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
