It can be understood that the hook 4 is locked with the chain when the elastic element 5 is in the initial state, and the pull-tab 3 acts on the hook 4 through the hollow hole 21 to compress the elastic element 5 so as to drive the hook 4 to rotate and move in the direction away from the chain for unlocking.

firstly, the base 1 and the upper cover 2 are detachably and fixedly connected, so that the base and the upper cover are convenient to separate and process during production, and the processing efficiency is improved;

second, elastic component 5 respectively with base 1 and horse collude 4 and offset the setting, the horse colludes 4 simultaneously and can rotate for base 1, and move along the direction of being close to or keeping away from the chain and carry out locking or unblock, and set up fretwork hole 21 on upper cover 2, act on horse colluding 4 through fretwork hole 21 through pulling-on piece 3, make horse collude 4 compression elastic component 5, and drive horse collude 4 and remove along the direction of keeping away from the chain and carry out the unblock, and after pulling-on piece 3 breaks away from fretwork hole 21, elastic component 5 resumes initial state and drives horse collude 4 and remove the locking along the direction of being close to the chain. The puller has the anti-theft lock function, is small and exquisite in shape, good in concealment and not easy to perceive and master the use mode; a single pull head cannot be unlocked, the pull piece 3 needs to be connected externally or unlocked by adopting other structures, and the safety is improved.

Specifically, one side that is close to fretwork hole 21 on the diapire of upper cover 2 still is equipped with spacing subassembly to carry on spacingly to pulling-on piece 3 when making pulling-on piece 3 be in fretwork hole 21.

The limiting component can be arranged to be opposite to each other and form a limiting lug 23 of a limiting groove between the limiting component and the pulling piece, and the pulling piece 3 is arranged in the limiting groove to prevent the pulling piece 3 from being separated from the hollow hole 21. Further, spacing subassembly is preset angle setting with fretwork hole 21 to it is spacing with spacing subassembly cooperation to rotate preset angle when pulling-on piece 3 is in fretwork hole 21. The pull piece 3 passes through the hollow hole 21 and then rotates by a preset angle to be in contact with the limiting bump 23, and the rotating motion of the pull piece 3 in the horizontal plane is limited, so that the pull piece 3 is further prevented from being separated from the hollow hole 21. In this embodiment, the hollow holes 21 are bar-shaped holes.

Wherein, elastic component 5 is the spring, is equipped with the elastic component 5 mounting groove that is used for installing elastic component 5 on the base 1. The elastic member 5 mounting groove is preferably provided as a circular groove to improve a position limiting effect on the elastic member 5.

On the basis of the above embodiments, the hook 4 includes the rotating shaft portion 41 for being rotatably connected with the base 1, the upper cover 2 and the base 1 are respectively provided with the rotating shaft limiting grooves 11, and the two rotating shaft limiting grooves 11 form the limiting cavity for limiting the rotating shaft portion 41. The upper cover 2 and the base 1 are respectively provided with a mounting seat for setting a rotating shaft limiting groove 11, the mounting seat of the base 1 is taken as an example for explanation, the number of the mounting seats is two, the two mounting seats are oppositely arranged, the distance between the two mounting seats is set according to the length of a rotating shaft part 41, the two end walls of the mounting seats are provided with the rotating shaft limiting grooves 11, the rotating shaft part 41 is lapped in the rotating shaft limiting grooves 11, meanwhile, when the upper cover 2 and the base 1 are installed, the mounting seat of the upper cover 2 is butted with the mounting seat of the base 1, the rotating shaft limiting grooves 11 are further butted to form a limiting cavity, and the rotating shaft part 41 rotates along the axis in the limiting cavity.

In one embodiment, one of the upper cover 2 and the base 1 is provided with a clamping protrusion 22, and the other of the upper cover 2 and the base 1 is provided with a clamping groove 12 matched with the clamping protrusion 22.

The circumference of upper cover 2 is equipped with four joint arch 22, is equipped with four draw-in grooves 12 rather than relative on the base 1, and whole draw-in grooves 12 set up along vertical direction, is equipped with the breach on the lateral wall that draw-in groove 12 set up along the horizontal direction simultaneously, and after joint arch 22 and draw-in groove 12 installation, the last bottom surface of joint arch 22 and lower bottom surface contact location with the last bottom surface and the lower bottom surface of breach respectively to carry on spacingly along the removal of vertical direction to upper cover 2.

The utility model also provides a zipper, including the chain, still include:

the pull tab 3 and the pull head of any of the above embodiments;

the pull tab 3 includes a key-like portion 31 for fitting with the hollow hole 21 for fixing, and the key-like portion 31 is a cylindrical key-like portion.
