The extension portion 22 has a width less than that of the main body 21. A positioning protrusion seat 23 is horizontally provided on the extension portion 22. The positioning protrusion seat 23 has a vertical through hole 24. A front end face of the positioning protrusion seat 23 is formed with a horizontal positioning trough 25 penetrating the inside of the positioning protrusion seat 23. A rear end of the positioning protrusion seat 23 is formed with a side through hole 26 penetrating the inside of the positioning protrusion seat 23 and communicating with the positioning trough 25. The side through hole 26 is transversely provided with a side positioning piece 27. The side positioning piece 27 is located at the same plane as the positioning trough 25. A C-shaped buckle 28 is provided to pass the positioning trough 25 and engage with the annular groove 3 of the rod body 2 of the hand tool 1 passing through the through hole 24, enabling the annular groove 3, the positioning trough 25 and the side positioning piece 27 to be at the same plane and enabling the C-shaped buckle 28 to be positioned between the positioning trough 25 and the side positioning piece 27. Through the aforesaid structure, the rod body 2 of the hand tool 1 is buckled by the C-shaped buckle 28 to be one-piece. The C-shaped buckle 28 is covered and hidden by the positioning protrusion seat 23, such that the hand tool 1 is unable to disengage from the display tag 20 to provide an anti-theft function. The assembly of the first embodiment of the present invention is described hereinafter. The C-shaped buckle 28 is a thin buckle ring made of a metallic or plastic material, so that it has the capability of elastic deformation to be embedded into the annular groove 3 of the rod body 2 of the hand tool 1 unless an external force is applied to the C-shaped buckle 28 to disengage it from the annular groove 3. When the hand tool 1 is inserted into the through hole 24 of the positioning protrusion seat 23, the C-shaped buckle 28 is embedded and limited in the positioning trough 25. The positioning trough 25 is a slot corresponding in shape and size to the C-shaped buckle 28 for the C-shaped buckle 28 to be covered and hidden by the positioning protrusion seat 23. Thus, it is unable to take out the C-shaped buckle 28 from the exterior of the positioning protrusion seat 23. Even if the display tag 20 is knocked, the C-shaped buckle 28 won't disengage from the annular groove 3 to depart from the positioning trough 25. This provides an anti-theft effect. Referring to FIG. 4, FIG. 6 and FIG. 7, when the user wants to disengage the hand tool 1 from the display tag 20, a pair of scissors 4 is used to cut the two sides of the side positioning piece 27 at the side through hole 26 from the back of the display tag 20 so as to open the side through hole 26 bigger.
