The installation and removal of fastener 230.In other embodiment of the present utility model, the hole clipping can also be fully located at stud main body
On.In the present embodiment, the flexible clamp piece 230 is located on end cap 213 and is at least partially disposed in hole clipping 211, the perforate
216 extend on the end cap 213, and in the present embodiment, the lower end of the perforate 216 can be opened wide and can not also open wide, institute
State screw rod 220 and extend to the part that perforate 216 is located on end cap 213.
In the present embodiment, the end cap 213 is provided with fluting 214, and the quantity of the fluting 214 is 3, the elasticity
Fastener 230 is also 3, and the flexible clamp piece 230 includes elastic component 231 and kelly 232, at least part position of elastic component 231
In in fluting 214, the inner of the elastic component 231 is connected with the kelly 232, and the part of the kelly 232 is located at hole clipping 211
In, the inner of the kelly 232 can abut with screw rod 220, the screw rod when the flexible clamp piece 230 is located at stretching state
220 promote kelly 232, and the kelly 232 compresses the elastic component 231, when the flexible clamp piece 230 is located at contraction state when institute
Elastic component 231 is stated by the mild compression of kelly 232 or be nature stretched condition.In the present embodiment, the elastic component 231
For spring, the outer end of the spring abuts the cell wall of fluting 214, and when elastic component 231 is located at stretching state, the spring is in
Compressive state.In addition, in other embodiment of the present utility model, the elasticity when the flexible clamp piece is located at stretching state
Part may be located on extended state.
In the present embodiment, the kelly 232 includes tight lock part 233 and elastic joint part 234, the tight lock part 233 with
The elastic joint part 234 is fixedly connected, and the inner outer end with the elastic joint part 234 of the elastic component 231 is connected, described
The inner of elastic joint part 234 can abut with screw rod 220, when the flexible clamp piece 230 is located at stretching state, the locking
The hole clipping 211 is stretched out in portion 233, and when the flexible clamp piece 230 is located at retracted mode, the tight lock part 233 is retracted into described
In hole clipping 211.In the present embodiment, the upper surface of the tight lock part 233 includes bearing surface, and the bearing surface is plane, is used for
Abutted when tight lock part 233 stretches out hole clipping 211 with the inner surface of inner side object 110.
In addition, in the present embodiment, in order to which the when marquis stud component 200 for preventing that nut 310 from tightening rotates with it together, institute
Stating stud component 200 also includes non-circular spacer 240, for example, shape such as square washer 240, regular hexagon pad 240, described
Non-circular spacer 240 is socketed on stud 210, the pad 240 can the relatively described lengthwise movement of stud 210, also can be with
Nut 310 1 towards the direction of end cap 213 move, and the pad 240 can not the relatively described rotary motion of stud 210, Ye Jisuo
Pad 240 is stated with the rotary motion together of stud 210, it is impossible to the rotary motion of pad 240, situations such as stud 210 is motionless, from
And as long as staff clamps non-circular spacer 240 to prevent non-circular spacer 240 from rotating with spanner, then tighten stud 210
On nut 310, because non-circular spacer 240 can not rotate in circumferential direction, can not rotate so as to stud 210, so as to
When nut 310 rotates, stud 210 will not be rotated with nut 310, so that nut 310 can be tightened, certainly, nut 310 is tightened
During, because nut 310 can apply the active force towards the direction of end cap 213, non-circular spacer 240 can vertically move, so as to
By the effect of kelly 232, non-circular spacer 240 and nut 310, the described two objects of clamping that can surely lean on.Specifically,
