The movement of shackle.
The utility model is further arranged to：Described locating piece is hex nut.
By adopting technique scheme, hex nut has three to the plane being oppositely arranged, and can facilitate to hexagonal
Rotation on threaded rod for the hex nut is realized in the effect of nut applying power, facilitates operation, improves the practicality of product.
The utility model is further arranged to：It is provided with outside described extension spring body, excessive body and shackle and black mould layer.
By adopting technique scheme, the black setting moulding layer, realize making the parcel of extension spring body, excessive body and shackle
With three can be placed and comes in contact with extraneous object and wear and tear, can also place three and directly send out with the steam of in the air
Life contacts and gets rusty, and improves the durability degree of product.
In sum, the utility model has the advantages that：The threaded rod of setting and positioning agllutination on extension rod
Close, realize the effect that shackle is limited, and when changing the position of locating piece, the elastic strength of extension spring can also be changed, carry
Rise working range.On threaded rod, the limited post of setting realizes the restriction to locating piece, and locating piece is without departing from threaded rod.And
The chamfering of circular arc is arranged on limited post, reduces the contact area of locating piece and limited post, decrease abrasion.And on limited post
The arc surface of setting then can reduce the abrasion of excessive body and extension spring body.The black setting moulding layer can place extension spring abrasion and life
Rust, improves the durability degree of extension spring.
