The invention discloses a zipper with handles and its application and installation on a trolley case. The zipper has a handle provided at one end of each left and right zipper chain for guiding the respective left and right zipper chain into the tooth groove of the slider. Each handle has a connecting piece used to fix with the cloth belt of the respective zipper chain. The thickness of each connecting piece and the respective cloth belt after being fixed is less than the gap between the upper cover plate and lower cover plate of the slider through which the cloth belt passes. Each connecting piece has a thin guide rod provided at one side thereof, and the guide rod is connected to the chain teeth of the respective zipper chain. The height and width of the guide rod is less than the height and width of the zipper chains.

In a slide fastener, at a slider pull-up start position in which an insert pin is inserted into an insert pin insertion hole of a box body and a slider is in contact with the front surface of the box body, an engaging head portion of the rearmost element of one fastener element row approaches or comes into contact with an engaging portion provided on the insert pin.

In a closed state of a zipper, distance from a tape-facing plane of an upper blade of a slider to a first tape at an end of a first terminal element facing a first row is different from distance from the tape-facing plane of the upper blade of the slider to the first tape at an opposite end of the first terminal element.

A bottom stop assembly includes a bottom stop fixing part and a movable pin. The bottom stop fixing part includes a box fixing part and a box connecting part, and the box fixing part is provided with a pin accommodating groove. One end of the box connecting part is connected to the box fixing part, and the other end is configured to be connected to a first tape. The movable pin has a first end for being inserted into and mated with the pin accommodating groove and a second end for being connected to a second tape, and a side of the box connecting part facing the movable pin is provided with a pin guide part which is a sloped structure inclined relative to a direction from a bottom towards an opening of the pin accommodating groove.
