When person from the first guide groove 55a end are moved to the second guide groove 55b stopper section 55c, the second cylinder 60 is by guide finger
80 draw and are moved along the longitudinal direction of the first cylinder 51.Herein, the second cylinder 60 is rotated around its own axis and along phase
For the inclined first guide groove 55a movements of longitudinal direction of the first cylinder 51, so as to open or close frame openings 15.This
It will be more fully described with reference to Figure 11 and Figure 12.
Figure 11 and 12 be respectively the lock cell for showing snap ring according to a preferred embodiment of the invention open mode and
The perspective view and partial section view of closed mode.
Figure 11 shows the open mode of the frame openings 15 of framework 10.Therefore, being arranged on the second of the first cylinder 51
The first end of the second cylinder 60 towards the first cylinder 51 in end is moved, so as in the first guide groove 55a end
Guide finger 80 enters the second guide groove 55b stopper section 55c.Herein, guide finger 80 by the elastic force of elastic component 72 towards stopper section
55c is promoted.Thus, guide finger 80 is not removed from stopper section 55c, unless relatively large external force is applied thereto.
So, when guide finger 80 is arranged in the second guide groove 55b stopper section 55c, the second cylinder 60 is adjacent to
The first end of one cylinder 51 is set, and thus the first end of the second cylinder 60 discharges the connection guide 16 and first of framework 10
Both locking pieces 53 of cylinder 51.Therefore, the frame openings 15 of framework 10 are opened.
Meanwhile, when guide finger 80 enters the second guide groove 55b stopper section 55c from the first guide groove 55a, it is connected to and leads
To the second cylinder 60 of pin 80 as guide finger 80 is around the axis rotation of its own, while, it is connected to guide finger 80
Movable piece 74 is rotated also with guide finger 80 around the axis of its own.Because elastic component 72 is only contacted without fixation with movable piece 74
To movable piece 74, therefore elastic component 72 will not be reversed because of the rotation of movable piece 74.In other words, movable piece 74 is around its own axle
Slide end while line is rotated relative to elastic component 72.So, even if due to being rotated when movable piece 74 around its own axis
When elastic component 72 also do not reverse, so elastic component 72 durability increase, it is possible thereby to reduce the replacement cost of part.In addition,
Because the independent attachment means that movable piece 74 is connected to elastic component 72 need not be used for, therefore production cost can be reduced.
Figure 12 shows the closed mode of the frame openings 15 of framework 10.Therefore, the second cylinder 60 is around its own axis
Backwards rotation.Then, the guide finger 80 in the second guide groove 55b stopper section 55c is removed from stopper section 55c, and towards the
One guide groove 55a first end movement.Hereafter, guide finger 80 due to elastic component 72 elastic force and towards the first guide groove 55a's
Second end is automatically moved, and is then inserted into fixed part 55d.By means of the elastic force of elastic component 72, guide finger 80 can be prevented not
Desirably removed from fixed part 55d, unless relatively large external force is applied thereto.Moreover, when guide finger 80 enters fixed part 55d
When, the second cylinder 60 is moved by guide finger 80 towards the second end of guide groove 55, and the end of the second cylinder 60 holds
Receive framework 10 connection the cylinder 51 of guide 16 and first locking piece 53 both.Finally, the frame openings 15 of framework 10
Close.In the same way, because elastic component 72 is not attached to movable piece 74, when movable piece 74 around its own axis rotate or
During backwards rotation, movable piece 74 is slided on the end of elastic component 72.Accordingly it is possible to prevent elastic component 72 is turned round by movable piece 74
Turn.
So, the present invention is configured so as to prevent the quilt of elastic component 72 when the second cylinder 60 is moved along the first cylinder 51
Reverse, the durability of elastic component 72 is thereby increased, so as to reduce the replacement cost of part.
Simultaneously, although have been illustrated with for shrinkage front to be connected into purse seine with the embodiment for the snap ring fished, but
It is that the present invention is not limited to the embodiment.For example, the snap ring of the present invention is used for being applied with the hawser or cable of heavy load
The other field of rope, so rope or hawser, which are placed, to be arranged in the first space 11 of framework 10, so as to reduce the He of framework 10
Frictional force between rope or between framework 10 and hawser.
As described above, in the snap ring with multiple rollers according to the present invention, in the first sidepiece and the second sidepiece at least
One diagonally oriented.Therefore, when shrinkage front is arranged in the first side roller or the second side roller, shrinkage front easily along the first sidepiece or
Second sidepiece is slided towards intermediate calender rolls.Therefore, pressure distribution on snap ring or multiple rollers is applied to the first side from shrinkage front
On roller and intermediate calender rolls or the second side roller and intermediate calender rolls, rather than concentrate on a roller.It therefore, it can extend the longevity of snap ring
Life, can also reduce the replacement cost of the part of snap ring.
In addition, snap ring of the configuration according to the present invention, to cause elastic component to be not affixed on movable piece.Therefore, can even if working as
Moving part with guide finger rotate together when, elastic component is not also reversed, therefore can increase the durability of elastic component.
