Anti-pinch puller easily replaceable in pull piece

Abstract

The invention discloses an anti-pinch puller easily replaceable in pull piece.The puller comprises a wedged block, an upper spring, a lower spring and a vertical column.A mounting groove is formed in one end of an upper puller board correspondingly to a supporting core in position, the wedged block is mounted in an upper groove of the mounting groove by moving up and down, and the supporting core is mounted in a lower groove of the mounting groove by moving up and down.A penetration bridge with a bent direction facing the wedged block is arranged at the other end of the upper puller board, so that a pull piece accommodating cavity is formed between the wedged block and the penetration bridge.The upper spring butts against a position between the vertical column and the wedged block, and the lower spring butts against a position between the wedged block and the supporting core.The vertical column passes through the upper spring, the wedged block, the mounting groove and the lower spring sequentially from top to bottom to be fixed on the supporting core which is fixedly connected on a lower puller board.The anti-pinch puller easily replaceable in pull piece is replaceable in pull piece quite conveniently and has a good anti-pinch effect so as to better protect clothes from being damaged.

Description

technical field [0001] The invention relates to a slide fastener, in particular to the improvement of the slider structure of the slide fastener. Background technique [0002] At the current stage, when the slider is hung with a pull piece, the pull piece is first inserted into the bridge of the nose, and the end of the nose bridge is riveted with the upper board by mechanical force. The pull piece is not easy to replace, and sometimes the bridge of the nose will be broken, resulting in defective products; During use, the cloth of the clothing sometimes gets caught in the cloth seam, and since the cloth seam distance does not change, it will cause damage to the zipper or the clothing to varying degrees, causing great inconvenience in use. Contents of the invention [0003] Aiming at the problems existing in the prior art, the present invention provides a slider which is anti-pinch and easy to hang the pull tab. The slider not only can replace the pull piece more convenien...
