And therefore prevent from discharging the second tightening member in the case of tension load securely while increase confining force.
In the case of aforementioned advances, in order to dismantle, the axle that the second tightening member have to be around pin part rotates such as 45 °
Or 90 °.Rotation causes to be pressed against the rib of the second tightening member on the region being radially projected into fastening acceptance division radially
Outwardly against the Part II of the locking member of the first tightening member so that fastener head is from the Part II of locking member and first
Discharged in the locking in free space between the carrier part of tightening member.For this can only by apply extremely strong pulling force and
Involved part is destroyed in the appropriate case discharges second from installation site by the pulling force on axial direction merely to realize
Tightening member.According to rotation into alignment, when fastening part is inserted into fastening acceptance division, it can also be rotated.However, due to
The geometry of second tightening member, this execution automatic during installation so that be used to install again without alignment before this.
In the case of the development, the higher installing force of needs and Geng Gao removal force, and the rotation of the second tightening member certainly
It is necessary.However, therefore, the higher confining force for example more than 400N can be realized in operation.Therefore, the development is same
Sample is particularly suitable for use in the situation that part will be fastened on the exterior lateral area of automobile.As described above, by appropriate development radially
The region of the Part II for the lock part being projected into fastening acceptance division, the second tightening member can be while rotary course
Fastening acceptance division is forced out in the axial direction, without with this end in view required any pulling force.
The rib of the pin part of second tightening member can be in radial directions in the tight of foundation and the second tightening member
Gu extend between head.In addition, being looked up from the fastener head to the side of the foundation, the rib can be around institute
Stating has cumulative ennation in the circumferential direction of fastening acceptance division.The development of rib again results in the second tightening member and enclosed
Fastening acceptance division is moved out of in the axial direction while being discharged from installation site during around the axis rotation of its pin.
According to other development, the foundation of second structural detail can form the bottom of kettle shape part, wherein
