[0003] The object of the present invention is to solve the problem of leaving expansion screw traces on the wall when the existing water drilling machine is drilling, and to provide a safe water drilling machine without traces on the wall, so that the supporting guide rod is in the center of the drilling hole, that is, it is in the position of being drilled off. In the center of the wall core, the wall core with expansion screws is removed after drilling the hole, leaving no fixing marks on the wall

Abstract
The invention relates to drilling machinery, in particular to a wall traceless safety water drilling machine. The wall traceless safety water drilling machine comprises a motor, a transmission device,a water drill bit, a wall fixing device, a guide rail 8 and a water pipe, wherein the wall fixing device comprises an expansion screw which is fixed on a wall and the guide rail which is in threadedconnection with the expansion screw, and the expansion screw and the guide rail are fixed to the center of a drilling hole; a sliding block is provided with a longitudinal central cavity, and the guide rail penetrates through the central cavity of the sliding block; a rack is arranged on the top surface of the guide rail, and a pinion meshed with the rack is arranged at the rear end of the slidingblock; the front end of the sliding block is a hollow cylinder, a driven gear is installed through a bearing, the water drill bit is installed on the driven gear, and the driven gear is meshed with adriving gear of the output shaft of the motor. The wall traceless safety water drilling machine has the beneficial effect that the sliding block 6 with the longitudinal central cavity 7 are arranged,the sliding block 6 with the longitudinal central cavity 7 can move along the guide rail, the expansion screw is fixed to the center of a wall drilling hole, the guide rail is fixed on the expansionscrew, the water drill is drilled in the drill hole namely the center of the drill hole through, the drilling wall core is removed after drilling hole, and no fixed mark is left on the wall, then, thesliding block 6 of an installation motor moves along a center guide rail, so that the drilling is labor-saving, stable, safe and positive in drilling.
Description
Technical field: [0001] The present invention relates to drilling rigs and in particular to water drilling rigs for drilling holes in walls. Background technique: [0002] The water drilling rig is a general-purpose wall drilling machine. It consists of a motor, a transmission device and a water drill bit. It is directly held by a person to drill holes. The hand-held water drilling machine is not only laborious and tiring, but also easily hurts people when the rig shakes. In order to change this situation, some of the current water drilling rigs have added an auxiliary support guide device, which is to fix the guide rod with the rack with expansion screws on the side of the wall that is ready to be drilled when drilling, so that the water drilling rig can move along the The guide rod is moved to drill the hole, which saves labor and avoids the drilling rig from hurting people. However, this improvement is to fix the guide rod on one side of the water drilling machine, that i...
