Detailed Description

The present invention will be further explained with reference to the drawings attached to the specification.

The cutter with lamp shown in fig. 1-3 and 4-6 comprises a handle 01 and a cutter head 02, wherein the cutter head 02 is rotatably assembled at the front end of the handle 01 through a shaft sleeve 03, a removable lamp assembly 04 is assembled in the shaft sleeve 03, and the end surface (the side surface relative to the handle) of the lamp assembly 04 is provided with a switch button 42 for controlling the on and off of a light source. When the knife is used, the light source can be turned on or off through the switch button. Because the lamp assembly can be taken out, the lamp assembly can be taken out from the shaft sleeve for independent use (such as hanging on a key buckle) when needed, and after the lamp assembly is taken out, the shaft sleeve can be used for fingers to extend into, so that the holding force of the handle is enhanced.

In the sleeve, one end of the sleeve in figures 2-3 is provided with a folded edge 33, the other end of the sleeve is connected with a nut 32 through threads, and the cutter head and the handle are assembled by means of clamping of the folded edge and the nut. The sleeve in fig. 6 is formed by butting two sections of shaft sleeves, one end of each section of shaft sleeve is provided with a folded edge, the other end of each section of shaft sleeve is provided with an internal thread and an external thread respectively, and the two sections of shaft sleeves are butted through the matching of the internal thread and the external thread to assemble the tool bit and the handle.

In order to illuminate the cutting portion at the time of cutting, the light source of the lamp assembly irradiates forward.
