KNIFE HAVING HANDLE ACCOMMODATING TOOL MEMBER
Document Type and Number:
WIPO Patent Application WO/2019/101181
Kind Code:
A1
Abstract:
A knife having a handle accommodating a tool member, comprising a handle (1) and a blade (2). The tail end of the blade (2) is connected to the front end of the handle (1); an accommodating recess (11) is provided at a position, in the handle (1), on a side of the blade (2); the accommodating recess (11) is provided, on the front end of the handle (1), with an opening for a tool member (3) to be inserted; the tool member (3) comprises a tool member body (32) and an operating member (31) connected and fixed to the tool member body (32); a compressible elastic member capable of enabling the operating member (31) to tightly press against the accommodating recess (11) is provided on the side of the operating member (31) close to the blade (2); a snap-fit block (313) is provided on the side of the operating member (31) close to the accommodating recess (11); a snap-fit slot (5) is provided at a position on the wall of the accommodating recess (11) corresponding to the snap-fit block (313); the snap-fit block (313) and the snap-fit slot (5) are in detachable snap-fit connection. The present invention has the advantage that: unlocking can only be implemented by applying an action force on the operating member (31) in a Z-axis direction, i.e., the direction from the exterior of the handle (1) to the interior of the handle (1); in addition, an action force is also required to be applied to an X-axis direction in order to take the tool member (3) out from the accommodating recess (11). That is to say, when the knife is in normal use or even impacted, the tool member (3) would not easily disengage from the accommodating recess (11), thereby implementing reliable locking.
