Abstract
Description
Technical Field
[0001] The utility model relates to a reset handle for a toilet water tank. Background Art
[0002] The existing toilet tank reset handle can be reset to facilitate drainage next time. The current reset handle is usually made by setting a torsion spring between the flange and the screw head, and the handle shaft passes through the torsion spring. Since the handle shaft is large in size, the inner ring size of the torsion spring is also large. If its service life needs to be guaranteed, the torsion spring needs to be made of coarser material. Such a large-sized torsion spring has a higher cost. If a thinner material is used, it may cause a situation where it cannot be reset, or: it is only used a small number of times, which greatly affects the service life of the handle.
