a. Preparation: using the body mold and the cover mold separately, the first plastic injection molding of the body 10, the first cover member 21, and then using a sheath mold to form a metal sheath 40; Preferably, the cover mold has upper and lower mold cavities, thereby ejecting one of the first cover member 21 and one of the non-transparent holes, and the second cover member is formed on the surface of the second cover member. The text or the pattern of the through hole is also indispensable, or the second cover member and the body are integrally formed by direct injection molding. The second end of the body is formed with a positioning protrusion 16 on at least one side, preferably two opposite sides. A positioning bump 16 is formed on the side.

b. second shot: the first cover member 21 is placed in the cover mold again, and a plastic 23 different from the color of the first cover member is injected into the cover mold, and the plastic 23 is formed in the cover a cover member 21 surface preset text or pattern of the shape of the through hole 24, thereby forming the marking member 20 of the predetermined text or pattern of the plastic layer 22;

c. The third shot: at least the indicator member 20 is disposed on the body 10, and the first stop portion 13 is radially abutted with the indicator member 20, and a portion of the plastic layer 22 is disposed on the body 10 Between the first cover member 21 and the first cover member 21, the indicator member and the second cover member are respectively disposed opposite to the body 10; and a cladding member 31 is injected to perform a third injection processing step. The cover material 31 is disposed on the body 10 portion of the second cover member;

d. Assembly: Finally, the pre-formed sheath 40 and the positioning projections 16 of the second end 12 of the body 10 are engaged with each other to form a tool grip.

Referring to FIG. 9 and FIG. 10, in the detailed step of covering at least one covering material 31 in the body 10, the body 10 is first covered with the marking member and placed in a tool grip mold 70. The tool grip mold 70 at least partially abuts the outer peripheral surface of the second end 12 and the outer side of the indicator member to form the tool grip mold 70, the body 10 and the indicator member at least one side surface in the circumferential direction. A second gap 71 is formed by injecting the at least one cladding material 31 into the second gap 71 to form the at least one cladding layer 30.
