Further, cover board is fixedly connected on body, and cover board is equipped with the hole for fastening tool insertion.
Further, the length of the aperture major part of stepped hole is less than the length of bolt.
Further, the entire length of stepped hole is more than the length of bolt.
Further, elastic component is compression spring.
Further, elastic component can also be elastic rubber ring.
Further, bolt is interior corner bolt.
Further, interior corner bolt is hexagon socket head cap screw.
Compared with the prior art, the fastening structure described in the utility model with free removal bolt has the advantage that：
With this configuration, when screwing out screw release connection, bolt automatic accomodation will not drop out in stepped hole.It uses next time
When, without being manually packed into new bolt, reduce workload, improve work efficiency；Step is remained in after disassembling bolts
In hole, facilitate management, reduce the loss in transport process；In addition, can make marks on the cover board when replacing bolt, prevent from losing
Leakage, ensure that assembling quality.
The another object of the utility model is to propose a kind of free removal bolt adaptation board, is provided with and exempts from as previously described
Remove the fastening structure of bolt.
Further, free removal bolt adaptation board is the adaptation board for engine assembly.
The free removal bolt adaptation board is had with the above-mentioned fastening structure with free removal bolt for the prior art
Advantage it is identical, details are not described herein.
Other features and advantages of the utility model will be described in detail in subsequent specific embodiment part.

Specific embodiment
It should be noted that in the case where there is no conflict, in the embodiment and each embodiment in the utility model
Feature can be mutually combined.
The utility model is described in detail below with reference to the accompanying drawings and with reference to embodiment.
Fig. 1 schematically shows a kind of fastening knot with free removal bolt of embodiment according to the present utility model
Structure.Fastening structure with free removal bolt includes bolt 1, elastic component 2, cover board 3 and body 4.
As shown in Figure 1, stepped hole 7 is offered on body 4.Bolt 1 is placed in stepped hole 7, and the nut of bolt is located at platform
The larger one end of the internal diameter in rank hole 7.Elastic component 2 is set in outside bolt 1.One end of elastic component 2 is resisted against the step surface of stepped hole 7
On, the other end is resisted against on the nut of bolt 1.Elastic component 2 is compression spring in the present embodiment.It is elastic in other practical applications
Part 2 can also be elastic rubber ring.One end that the aperture of stepped hole 7 is larger is equipped with cover board 3.Cover board 3 is fixedly connected on body 4
On, for closing stepped hole 7 to accommodate bolt 1 and prevent the abjection out of stepped hole 7 of bolt 1.Cover board 3 is equipped with for fastening tool
The hole of insertion, in order to which tightening tool stretches into dismounting and fastening bolt 1 in stepped hole from the hole.For the ease of the installation of bolt 1,
Bolt 1 uses interior corner bolt, can be specifically hexagon socket head cap screw.The length of the aperture major part of stepped hole 7 is less than bolt 1
Length, so by bolt 1 after fixated body is unscrewed, bolt 1 will not be complete from the smaller part abjection in the aperture of stepped hole 7
Into in the aperture major part of stepped hole 7, facilitate and tighten operation next time.The entire length of stepped hole 7 is more than the length of bolt 1
Degree, so by bolt 1 after fixated body is unscrewed, bolt 1 can be generally housed in stepped hole 7, prevent bolt 1 from stretching out step
Outside hole 7, security risk is caused.
The utility model additionally provides a kind of free removal bolt adaptation board.Fig. 2 schematically shows the utility model
A kind of embodiment free removal bolt adaptation board assembling workpiece after view.
As shown in Fig. 2, free removal bolt adaptation board is provided with the fastening structure with free removal bolt described above.It should
Free removal bolt adaptation board includes bolt 1, elastic component 2, cover board 3 and adaptation board body 8.Platform is offered on adaptation board body 8
Rank hole 7.Free removal bolt adaptation board can be the adaptation board for engine assembly, to be suitable for the engine of various models dress
Match somebody with somebody.In the assembled condition, the screw hole 5 corresponding on engine cylinder body 6 of stepped hole 7 is aligned.
When using the engine adaptation board of the above-mentioned fastening structure with free removal bolt, tighten adaptation board 8 with it is to be installed
During with workpiece, man-hour manually hand-held tightening tool stretches into tappet head in the hole of cover board 3, firmly depresses bolt 1, while rotates spiral shell
Bolt 1, bolt 1 are connected on engine cylinder body 6 with 1 matched screw hole 5 of bolt, and compression spring is most short at this time, in compression shape
State.When unclamping adaptation board body 8 with engine, man-hour manually hand-held tightening tool stretches into tappet head in the hole of cover board 3, reversely twists
Dynamic bolt 1, makes bolt 1 depart from the screw hole on engine, and the bolt 1 of release is ejected the spiral shell until bolt 1 by compression spring release
Crown is on cover board 3.In this way, after the completion of removing, bolt 1 is remained in stepped hole 7.
When replacing bolt 1, cover board 3 is removed, old bolt is taken out and is packed into new bolt, then installs cover board 3.
The foregoing is merely the better embodiments of the utility model, are not intended to limit the utility model, it is all
