Two relative folder valve parts, the phase heteropleural of this two folders valve part has respectively two Extendible flakes, and the top of this two Extendible flake, bottom surface have respectively a guide groove, and this two folders valve part is to be installed in respectively in the hollow-out parts of this ratchet head;

Two hollow lids, the bottom surface desired location of this two lid is respectively equipped with two breach, and the position of contiguous this two breach of the end face of this two lid is respectively equipped with two perforations, this two lid is to install respectively top, the bottom surface that is positioned this ratchet head, making each breach, proper must to press from both sides the Extendible flake of valve part accommodating for each, and utilize some prick posts to be arranged in respectively each perforation, the bottom of each prick post is placed in respectively on each guide groove.

Wherein, this positioning component is comprised of spring and steel ball.

Wherein, the outer peripheral edges of this two lid are provided with the on-slip line.

Wherein, this two folders valve part is to be く shape.

Wherein, the central desired location of this two folders valve part has respectively a groove, and each groove wears for a magnetic absorption member respectively.

Wherein, this magnetic absorption member is to be magnet.

The utility model advantage and effect are: provide a kind of user of convenience to operate use, and save time, labour-saving many size ratchet spanners of capable of regulating structure.
