Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, any modifications, equivalent replacements, improvements, etc. made by other embodiments obtained by a person having ordinary skill in the art without making creative efforts shall be included in the protection scope of the present invention.

As shown in fig. 1 to 4, the embodiment discloses a novel engraving cutter with a replaceable cutter head, which comprises a cutter handle 1 and a cutter head 2, wherein the cutter handle 1 is in bolted connection with the cutter head 2; the knife handle 1 is a wooden knife handle or other knife handles made of materials, such as a deer-horn knife handle and the like, and is arranged in a cylindrical shape, an installation groove 101 is formed in one end head of the knife handle 1, a fixed threaded sleeve 5 is fixedly connected in the installation groove 101, and the axial direction of the fixed threaded sleeve 5 is consistent with that of the knife handle 1; one end of the tool bit 2 is welded with a screw rod 3, the axial direction of the screw rod 3 is consistent with the length direction of the tool bit 2, one end of the screw rod 3, which is far away from the tool bit 2, is inserted into the fixed threaded sleeve 5, and the screw rod 3 is in threaded connection with the fixed threaded sleeve 5; one end of the screw rod 3 close to the tool bit 2 is provided with a limiting convex ring 301, the limiting convex ring 301 is sleeved outside the circumference of the screw rod 3, and the limiting convex ring 301 and the screw rod 3 are integrally formed.

The outer side of the screw 3 is sleeved with a screwing nut 4, the screwing nut 4 is in threaded connection with the screw 3, two wrench clamping surfaces 401 are symmetrically arranged on the outer side wall of the screwing nut 4, and the two wrench clamping surfaces 401 are parallel to each other. After the screw rod is in threaded connection with the fixed threaded sleeve, in order to avoid the phenomenon that the screw rod is loosened in the using process, the screwing nut is rotated and is in close contact with the end face of the fixed threaded sleeve, so that the connection relation between the screw rod and the fixed threaded sleeve is firmer; people can use the bayonet of the wrench to clamp the wrench clamping surface of the screwing nut to screw the screwing nut, so that the operation is more labor-saving.

A central through hole 102 is formed in the center of the tool shank 1, the axial direction of the central through hole 102 is consistent with the axial direction of the tool shank 1, an accommodating groove 103 is formed in one end, far away from the mounting groove 101, of the tool shank 1, and a metal striking plate 7 is embedded in the accommodating groove 103; one end of the central through hole 102 is communicated with the mounting groove 101, and the other end of the central through hole 102 is communicated with the accommodating groove 103; a central rod 6 is inserted in the central through hole 102, one end of the central rod 6 is welded with a fixed threaded sleeve 5 arranged in the mounting groove 101, the other end of the central rod 6 is provided with an external thread and is in threaded connection with a connecting screw hole 701 arranged on the top end face of the striking plate 7 through the external thread, and the bottom end face of the striking plate 7 is flush with the bottom end face of the tool shank 1.
