Description

Slider with replaceable blade

Technical Field

The utility model relates to a slider with replaceable blade.

Background

The pull head generally comprises a slider and a pull piece arranged on the slider, the slider is arranged in the zipper in a penetrating way, and the slider is driven to slide through the pull piece, so that the opening and closing of the zipper are realized. Besides the function of assisting in pulling the sliding block, the pulling piece can also be designed in a certain shape and style, so that the pulling head is endowed with different styles, and the pulling head can be used for clothes of different styles. Different pulling-on pieces can be designed for the same sliding block, and the pulling-on pieces can be replaced according to requirements, so that the pulling head with the replaceable pulling-on pieces is formed.

For example, in the chinese invention patent with application publication No. CN110367654A entitled "a zipper puller with replaceable pull piece and a method for replacing the pull piece", a zipper puller with replaceable pull piece is disclosed, which comprises a puller, a pull piece, a cap, a spring plate and a hook, wherein the puller is provided with a placing part for placing the hook, the hook is provided with a rotating part matched with the mounting part, the contact surface of the placing part and the rotating part is an arc surface, the hook comprises a stop hook, the pull piece is provided with a positioning rod, the spring plate is fixedly mounted at the top of the inner side of the cap, the cap is fastened at the position of the hook on the puller, the spring plate presses the top of the hook to drive the hook to rotate downwards around the placing part, so that the stop hook of the hook and the puller form a containing cavity for placing the positioning rod, the stop hook is bent towards the inside of the containing cavity, and two side faces of the cap are provided with side openings, an opening used for installing the pulling piece is formed in one side face, close to the stopping hook, of the cover cap, and the opening is communicated to the side opening. The pull tab of this patent requires, when it is replaced, a tool (for example, a relatively small screwdriver) to be inserted into the cap and to jack the hook, so that the hook is turned at a certain angle, and the pull tab can be removed from the hook, which is relatively troublesome to replace.

In another Chinese utility model entitled "a novel self-locking zipper puller convenient for replacing zipper puller", as in the granted publication No. CN202819881U, a novel self-locking zipper puller convenient for replacing zipper puller "comprises a puller body, the puller body comprises an upper wing, a lower wing, a spring, a pin shaft and a horse hook, the upper wing and the lower wing are connected by a zipper post to form a channel for zipper teeth to pass through, the upper end face of the upper wing is located at one end of the zipper post and is integrally formed with a pull nose along the other end direction, the pull nose and the upper wing form an opening for loading the zipper puller, the upper wing below the pull nose is provided with a through hole, two sides of the through hole are respectively provided with a limit bulge, the pull nose is provided with a strip-shaped hole for providing a movable space for the horse hook from the upper end face downwards, the upper wing located at one end of the zipper post is provided with a vertical spring slot along the zipper post, the spring is placed in the spring slot, a radial through hole is arranged on the side wall of the pull nose connected with the upper wing piece in a penetrating way, a lock needle arranged in the through hole in a penetrating way is formed at the lower part of the horse hook, one side of the horse hook is bent downwards to form a limit hook, the lock needle and the limit hook form a semi-closed groove for accommodating the pull piece, a pin hole is formed at the other side of the horse hook, the horse hook is arranged in the strip-shaped hole, the pin shaft penetrates through the radial through hole and the pin hole to fix one end of the horse hook, the lower part of one side of the horse hook is pressed on the spring, the limit hook and the limit bulge at the other side lock the pull piece in the semi-closed groove, and the lock needle at the lower part penetrates out of the lower part of the through hole; after one side of the horse hook is stressed to compress the spring, the limiting hook on the other side is lifted to open the semi-closed groove so as to replace the pulling piece. In this patent, for make the horse hook more convenient operation, set up the arch on the horse hook, the arch is higher than the cap, when the operation, through pressing the arch, can realize the swing of horse hook, the change of pulling-on piece is more swift. But the bulge protrudes out of the cap and is relatively convex, so that the bulge is easily accidentally scraped to cause potential safety hazards, and in addition, when the bulge is accidentally extruded, the slippage of the pull piece can be caused.

Accordingly, the present inventors have made extensive studies on the above problems and have made the present invention.
