BACKGROUND OF INVENTION [0001] 1. Field of Invention [0002] The present invention relates to windshield wipers and, more particularly, to a grinder for windshield wipers. [0003] 2. Related Prior Art [0004] Windshield wipers are important equipment for vehicles. The quality of windshields determines whether rain can completely be wiped from the windshields of the vehicles. Whether rain can completely be wiped on the windshields determines whether drivers can have clear view through the windshields. Clear view is very important for the safety of the drivers' safety and/or pedestrians who are nearby. [0005] A typical windshield wiper includes a rubber strip for wiping rain from a windshield and a frame for carrying the rubber strip. When newly installed, windshield wipers generally can wipe rain from windshields completely. However, after used for some time, the rubber strips of the windshield wipers will inevitably be hardened and fail to wipe rain from the windshields completely. In early days, users have no choice but to replace used windshield wipers with new ones. Later, users are allowed to replace only used rubber strips with new ones. Now, users can grind hardened tips of used rubber strips of windshield wipers so that the used rubber strips of windshield can become like new. [0006] Shown in FIG. 9 is a conventional grinder for windshield wipers. The grinder includes a body 1 with two contact faces 4 on two sides and two flat faces 2 at two ends. A piece of sandpaper 3 is adhered to each of the flat faces 2. A user can hold the grinder by the contact faces 4 and use the sandpaper 3 to grind a tip of a rubber strip 5 of a windshield wiper. However, it is difficult to keep the sandpaper 3 on the tip of the rubber strip 5 since the latter tends to buckle while being ground by the former. [0007] Shown in FIG. 10 is another conventional grinder for windshield wipers. This grinder includes two V-shaped faces 6 instead of the flat faces 2. The V-shaped faces 6 can firmly receive the tip of the rubber strip 5 of the windshield wiper. However, it is difficult to attach the sandpaper 3 to the V-shaped faces 6. [0008] The present invention is therefore intended to obviate or at least alleviate the problems encountered in prior art. SUMMARY OF INVENTION [0009] According to the present invention, a grinder includes two plates and two pieces of sandpaper. Each of the plates includes at least one bent portion, a sandpaper side and a finger side opposite to the sandpaper side. The pieces of sandpaper are attached to the sandpaper sides of the plates before the plates are connected to each other so as to form at least one V-shaped structure for receiving a tip of a rubber strip of a windshield wiper. [0010] An advantage of the grinder of the present invention is that the sandpaper can easily be attached to the sandpaper sides of the plates. [0011] Another advantage of the grinder of the present invention is that the V-shaped structure can firmly receive the tip of the rubber strip of the windshield wiper. [0012] Still another advantage of the grinder of the present invention is its easy fabrication. [0013] Other advantages and features of the present invention will become apparent from the following description referring to the drawings. BRIEF DESCRIPTION OF DRAWINGS [0014] The present invention will be described through detailed illustration of five embodiments referring to the drawings. [0015] FIG. 1 is a perspective view of a grinder for windshield wipers according to the first embodiment of the present invention. [0016] FIG. 2 is an exploded view of the grinder shown in FIG. 1. [0017] FIG. 3 is a cross-sectional view of the grinder shown in FIG. 1. [0018] FIG. 4 is a perspective view of a windshield wiper ground by means of the grinder shown in FIG. 1. [0019] FIG. 5 is a cross-sectional view of a grinder according to the second embodiment of the present invention. [0020] FIG. 6 is a cross-sectional view of a grinder according to the third embodiment of the present invention. [0021] FIG. 7 is a cross-sectional view of a grinder according to the fourth embodiment of the present invention. Continue reading about Grinder for windshield wipers...
