11, the 4th side wall 126 of arcuate structure 12 is preferably oppositely arranged, and arcuate structure 12 passes through the axis pin 22 that is arranged in mounting hole 21
Rotation is realized to be switched between rounding state and opening state, wherein arcuate structure 12 is under gravity or biasing member effect
Opening state is switched to by rounding state, not only reduces energy expenditure, and ensure that the reset of arcuate structure 12.Arc knot
Structure 12 further includes limiting section 123, and limiting section 123 includes confined planes 1231, it is preferable that two arcuate structures 12 are opposite in the circumferential
End face form confined planes 1231, confined planes 1231 are preferably provided to the plane with the radial intersection of arcuate structure 12, are opening
State, the confined planes 1231 on two arcuate structures 12 lean, so that the confined planes of one of arcuate structure 12
1231 can limit another arcuate structure 12 in opening state, and the confined planes 1231 of two arcuate structures 12 are respectively to another
A arcuate structure 12 is limited, to ensure that arcuate structure 12 is in the open state.
Retention device further includes the force section 3 being connected with arcuate structure 12, and force section 3 includes force-applying piece 31, such as Fig. 1 and 2
Shown, force-applying piece 31 is elongated, and one end of elongated force-applying piece 31 is connected with one end of arcuate structure 12, and force section 3 can be
Arcuate structure 12 is driven to turn to rounding state so that coiled strip 5 is resisted against on blocking surface 11 from opening state under the action of volume needle 4.
In opening state, force-applying piece 31 is arranged in a crossed manner, and volume needle 4 is moved down along the radial direction of coiled strip 5, and the lateral wall of volume needle 4 acts on force-applying piece
On 31, and then moving down with volume needle 4 so that the angle between two force-applying pieces 31 becomes larger, with the angle between force-applying piece 31
Degree becomes larger, and blocking portion 1 is rotated around axis pin 22, so that two arcuate structures 12 are gradually collapsed and coated with that will roll up needle 4, preferably
Ground, force section 3 and blocking portion 1 are integrally formed or are welded together, and arcuate structure 12 further includes holding part 124, an arc
Holding part 124 in shape structure 12 is for the accommodating force-applying piece 31 being connected with another arcuate structure 12, in this way, working as force-applying piece 31
