The utility model relates to a slider with a liquid guide hole.

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 needs, so that the pulling head with the replaceable pulling-on pieces can be formed, the pulling head with the replaceable pulling-on pieces in the market is complex in structure and more in parts, coatings on the parts can interfere with each other and even are combined together after the pulling head is assembled and subjected to surface treatment, and the flexibility of the operation of the pulling head is influenced. Although the number of parts of the slider is small, the slider is complex to machine and assemble.

In addition, the slider with replaceable pull tab also needs to be designed with consideration on how to quickly replace the slider. Therefore, the applicant discloses a novel quick-change pull head in the Chinese utility model patent application with the application number of 202122323241.8 and the name of "novel quick-change pull head", and the quick change of the pull piece can be realized.
