[0030] As shown in Figure 2 and Figure 6 As shown, the pen head 2 includes a fixed end 21 and an adsorption end 22, which are of an integrated structure. The fixed end 21 is fixedly connected with the diamond-embedded pen body 1, and the adsorption end 22 is uniformly provided with a plurality of adsorption grooves on the surface.

[0035] In use, the user starts the vacuum pump 4 by pressing the key switch 14, so that the air around the adsorption groove can be sucked in, and the air flows along the air inlet channel 23 to the inside of the negative pressure pipe 5. Before the air reaches the vacuum pump 4, the filter partition 9 effectively filters the impurities such as dust. As the vacuum pump 4 continuously extracts air, the external diamond is adsorbed onto the adsorption groove of the pen head 2 under the action of the pressure difference, thereby achieving the diamond setting effect. When the vacuum pump 4 stops working, the external air slowly enters the adsorption groove through the small gap, so that the negative pressure in the adsorption groove gradually balances with the external atmospheric pressure. As the air pressure difference decreases, the adsorption force also gradually weakens, and finally the diamond setting loses the negative pressure and naturally falls off, achieving the diamond setting effect.

Any person skilled in the art can easily think of changes or replacements within the technical scope disclosed in the present application, which should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
