Title: UTILITY KNIFE WITH REPLACEABLE BLADE
Abstract:
A utility knife (100) with a replaceable blade comprises a knife handle (109), a knife holder (107), a blade (105), and a locking device for fixing the blade (105) on the knife holder (107). The knife holder (107) and the blade (105) are switchable between a first position and a second position. When the knife holder (107) and the blade (105) are located at the first position, the blade (105) can be used for cutting, and when the knife holder (107) and the blade (105) are located at the second position, the knife holder (107) and the blade (105) are received in the knife handle (109). The utility knife (100) further comprises limiting devices (106a, 106b, 106c, 106d, 106e, 110). When the knife holder (107) is located at the second position and the locking device is in an unlocking state, the limiting devices (106a, 106b, 106c, 106d, 106e, 110) prevent the blade (105) from falling off from the knife holder (107) by limiting the displacement of the blade (105) relative to the knife holder (107). Further provided is a folding utility knife (100) with the replaceable blade (105), a retractable utility knife (100) with the replaceable blade (105), and a utility knife (100) with the replaceable blade (105) and multiple knife heads.
