[0001] This application is a Continuation-in-Part of pending application U.S. Ser. No. 11/514,362, entitled "WATER GRINDER" and filed on Sep. 1, 2006. FIELD OF THE INVENTION [0002] The present invention is related to a grinding device, and more particularly to a handheld grinder with wetting effect. The water incoming flow way of the grinder is disposed in the grinder. In addition, the water-discharging switch of the grinder is easily operable. BACKGROUND OF THE INVENTION [0003] When grinding a work piece with a handheld grinder, much powder dust is produced. The conventional grinder is designed with a water-discharging unit for wetting the powder dust and avoiding flight thereof. [0004] FIG. 1 shows a conventional handheld wet grinder 10 in which a water pipe 12 is mounted on the main body 14 for connecting with a water source. A water-discharging switch 16 is connected to the water pipe 12. When the switch 16 is switched on, the water will flow into the water pipe 12 and then flow out from the rotary shaft 18 of the grinder. [0005] In the above handheld wet grinder, the water pipe 12 is externally added to the main body and exposed to outer side thereof. In use, the water pipe tends to be collided and broken to lead to leakage of the water. [0006] Moreover, the water-discharging switch 16 is positioned at a rear end of the main body 14 so that it is inconvenient to operate the switch 16. That is, when controlling the water flow, a user needs to hold the main body 14 with one hand and switch the switch 16 with the other hand. Therefore, it is necessary for the user to use both hands to operate the grinder, unable to operate with single hand. SUMMARY OF THE INVENTION [0007] It is therefore a primary object of the present invention to provide a handheld wet grinder in which the flow way of the water is protected from being collided and broken. [0008] It is a further object of the present invention to provide a handheld wet grinder having a water-discharging switch for controlling water flow. The wet grinder enables a user to operate the water-discharging switch with single hand. [0009] According to the above objects, the handheld wet grinder of the present invention has a water incoming flow way which is directly disposed in the main body of the grinder. Therefore, the water incoming flow way is protected from being collided and damaged. [0010] The grinder of the present invention has a water-discharging switch positioned at a front end of the main body. Accordingly, a user can conveniently operate the water-discharging switch with the hand holding the main body. Therefore, the user can operate the water-discharging switch with single hand. [0011] Preferably, the water-discharging switch is positioned on a top face of the front end of the main body of the grinder. [0012] Preferably, the water-discharging switch is back and forth shiftable along the length of the main body. Alternatively, the water-discharging switch is rotatable to control the water flow. [0013] The present invention can be best understood through the following description and accompanying drawings wherein: BRIEF DESCRIPTION OF THE DRAWINGS [0014] FIG. 1 is a perspective view of a conventional wet grinder; [0015] FIG. 2 is a perspective view of a first embodiment of the present invention; [0016] FIG. 3 is a longitudinal sectional view according to FIG. 2; [0017] FIG. 4 is a sectional view taken along line 4-4 of FIG. 3; [0018] FIG. 5 is a side view according to FIG. 2; [0019] FIG. 6 is a side view according to FIG. 5, showing that the water-discharging switch is switched to the shutoff position; [0020] FIG. 7 is a perspective view of a second embodiment of the present invention; and Continue reading about Handheld wet grinder...
