31 or the lesser line of other elastic force, it is preferred that flexible wires use polyester thread 31, and flexible wires hereinafter use 31 table of polyester thread
Show.Each polyester thread 31 is wound around respectively on guiding device 5, and each polyester thread 31 also curls in setting Thread holder 6 respectively and passes through storage
Wire box 6, the length that each winding of polyester thread 31 is arranged in Thread holder 6 is each unequal, and each polyester thread 31 is close to one end of Thread holder 6
It is also respectively wound around on wire spool 7, wire spool 7 is connected with the transmission of take-up driving device.Since each polyester thread 31 is in Thread holder 6
The length of winding is each unequal, when take-up driving device drives wire spool 7 to rotate take-up, can successively receive each polyester thread 31
Tightly, and it is non-interference, it is independent of each other, it is easy to operate, simplify structure.
Further improved, polyester thread 31 is connected with elastic thread 3 by connecting terminal, polyester thread 31 without elastic thread 3 that
Big elasticity, polyester thread 31 are particularly suited for take-up than elastic thread 3.Pass through connecting terminal between elastic thread 3 and polyester thread 31
Connection, connecting terminal are the structure that clip etc. can connect the two.Or it can also be by elastic thread 3 and polyester thread 31 using knotting
Mode connect.
Further improved, Thread holder 6 includes box body 61, is inserted with muti-piece storage line piece 62 in box body 61, storage line piece 62
Quantity and the quantity of polyester thread 31 are equal, and each polyester thread 31 is wrapped in one by one on corresponding storage line piece 62.It is hollow in box body 61
Structure can successively plug multi-disc storage line piece 62, and in the present embodiment, the quantity of storage line piece 62 is four pieces.The top of box body 61
Multiple columns 63 are respectively equipped with bottom, box body 61 is detachably secured in gun body 1 by column 63.Storage line piece 62 is equipped with card
Piece 621, box body 61 are equipped with card hole 611, and storage line piece 62 is fixedly connected in box body 61 by the cooperation of card 621, card hole 611
Portion.
