1. The utility model relates to the field of door and window handles, in particular to a lifting handle.
Background technique:
2. The lifting handle, that is, the lifting sliding door handle, is used on the lifting sliding door. The lever principle is used to control the lifting and lowering of the lifting sliding door through the lifting handle, so as to realize the locking and opening of the lifting sliding door. The existing lifting handle will be subjected to a force opposite to the rotation direction each time it is rotated. In the case of long-term use, due to too many rotations, loosening will occur, thereby affecting the use of the lifting handle.
