Utility Model Content

[0003] The utility model solves the problem of unstable connection structure between the existing knife and the scabbard.

[0004] The technical scheme adopted by the utility model is: a multifunctional knife with a lock, comprising a scabbard, a blade and a handle, wherein one end of the blade is arranged in the handle, and the end of the blade with a blade edge is arranged in the scabbard, and the blade edge of the blade can be driven to be retracted into the scabbard or pulled out from the scabbard by holding the handle, a locking spring piece is arranged in the blade, one end of the locking spring piece is arranged in the handle and the other end extends to the outside of the handle, the locking spring piece on the outside of the handle is provided with a lock buckle, a pushing column is provided in the locking spring piece, and the pushing column extends to the surface of the handle, a locking groove is provided on the side of the scabbard corresponding to the locking spring piece, and a positioning plate is provided in the locking groove, and when the blade is inserted into the scabbard, the lock buckle at the end of the locking spring piece is arranged in the locking groove and is buckled and connected with the positioning plate.

[0005] Furthermore, an arc-shaped recessed portion is provided at the end of the knife handle, and a prying hook is provided at one end of the blade, and the prying hook is arranged in the arc-shaped recessed portion.

[0006] Compared with the prior art, the utility model has the following beneficial effects: when the blade is inserted into the scabbard, the lock buckle at the end of the locking spring piece is arranged in the locking groove and is buckled and connected with the positioning plate, so that the blade of the blade is locked in the scabbard; when the blade needs to be taken out of the scabbard to cut an object, the pushing column on the surface of the handle is pressed to make the locking spring piece move the lock buckle out of the locking groove; at this time, pulling the handle can drive the blade to be taken out of the scabbard for use; the structure is simple and the operation is convenient.

[0014] like Figures 1 to 6 A multifunctional knife with a lock comprises a scabbard 10, a blade 20 and a handle 30. One end of the blade 20 is arranged in the handle 30, and the end of the blade 20 with a blade is arranged in the scabbard 10. By holding the handle 30, the blade 20 can be driven to be retracted into the scabbard 10 or pulled out from the scabbard 10. The blade is arranged in the scabbard 10 to prevent accidental scratches by the blade and better protect the blade from deformation.

[0015] The blade 20 is provided with a locking spring 11, one end of which is arranged in the handle 30 and the other end extends to the outside of the handle 30. The locking spring 11 on the outside of the handle 30 is provided with a lock buckle 12, and the locking spring 12 is provided with a push column 13, which extends to the surface of the handle 30.

[0016] A locking groove 21 is provided on one side of the scabbard 10 corresponding to the locking spring piece 11, and a positioning plate 22 is provided in the locking groove 21. When the blade is inserted into the scabbard 10, the lock buckle 12 at the end of the locking spring piece 11 is arranged in the locking groove 21 and is snap-connected with the positioning plate 22, so that the blade 20 is locked in the scabbard 10. When the blade needs to be taken out of the scabbard 10 to cut objects, the push column 13 on the surface of the handle 30 is pressed to make the locking spring piece 11 move the lock buckle 12 out of the locking groove 21. At this time, pulling the handle 30 can drive the blade to be taken out of the scabbard 10 for use.

[0017] The end of the knife handle 30 is provided with an arc-shaped recessed portion 31 , and one end of the blade 20 is provided with a prying hook 23 , which is arranged in the arc-shaped recessed portion 31 . When in use, the bottle cap of the container can be pried open by the prying hook 23 at the end of the knife handle 30 .
