[0019] The preferred technical solutions of the present utility model will be described in detail below with reference to the drawings.

[0020] A device for processing drilling defects of a sofa bed frame, as Figures 1 - 3As shown in the figure, it includes a housing 1, anti-slip patterns 2, a button 3, a dust cover 4, a grinding drill bit 5, a polishing drill bit 6, a connecting piece 7, a nut 8, a protective cover 9 and a motor 10. A protective cover is provided on the upper part of the housing 1. Anti-slip patterns 2 are provided on the outer side of the housing 1 for easy hand-holding. A button 3 is slidably connected to the front side of the middle part of the housing 1. A protective cover 9 is connected to the lower part of the housing 1. The protective cover 9 is made of stainless steel, having good protection and durability. A dust cover 4 is snap-connected to the protective cover 9. The dust cover 4 is made of plastic, having good wear resistance, corrosion resistance and impact resistance. Two motors 10, upper and lower, are connected inside the housing 1. The output shafts of the motors 10 both pass through the housing 1 and are connected with a connecting piece 7. A grinding drill bit 5 is snap-connected to the lower connecting piece 7, and a polishing drill bit 6 is snap-connected to the upper connecting piece 7. Nuts 8 are threadedly connected to the connecting pieces 7 respectively.

[0021] When it is necessary to process the drilling defects of the sofa bed frame, this device can be used. Bring this device to the place where the drilling defects of the sofa bed frame need to be processed. Remove the dust cover 4 so that the dust cover 4 is separated from the protective cover 9. The dust cover 4 is made of plastic, having good wear resistance, corrosion resistance and impact resistance. Remove the protective cover so that the protective cover contacts the housing 1. Then hold this device and make the grinding drill bit 5 contact the position on the sofa bed frame where drilling is required. Use the anti-slip patterns 2 for anti-slip. Then push the button 3 downward by hand to start the lower motor 10. Drive the connecting piece 7, nut 8 and grinding drill bit 5 to rotate through the lower motor 10, and then drill the sofa bed frame. During drilling, protect with the protective cover 9 to prevent sawdust from splashing. The protective cover 9 is made of stainless steel, having good protection and durability. After drilling is completed, push the button 3 upward by hand, then make the polishing drill bit 6 contact the drilled position, and move the button 3 upward to start the upper motor 10. Drive the connecting piece 7, nut 8 and polishing drill bit 6 to rotate through the upper motor 10, and then polish the drilling defects, so that the sofa bed frame can be drilled and polished. The operation is simple, easy to carry, and improves the convenience of using this device. After use, close the upper motor 10 by pushing the button 3 downward. Then snap the dust cover 4 onto the protective cover 9 and snap the protective cover onto the housing 1, so as to protect the grinding drill bit 5 and the polishing drill bit 6, prevent dust from adsorbing on the drill bits, and extend the service life of the drill bits. When the drill bits are damaged and cannot be used, twist the nut 8 by hand. Under the action of the thread, the nut 8 moves so that the nut 8 is separated from the connecting piece 7, and then remove the grinding drill bit 5 or the polishing drill bit 6, so that the grinding drill bit 5 and the polishing drill bit 6 can be disassembled, which is convenient for replacing the grinding drill bit 5 and the polishing drill bit 6 and reduces the maintenance cost.
