Embodiment Construction
[0008] The elastic bending reset positioning device for hand-held drill bit, its structure is as follows figure 1 As shown, it is composed of a tapered deep cavity fixing jacket 1 at the non-rotating position of the drill bit, a fixing bolt 2, an elastic bending reset steel plate 3, a chassis fixing bracket 5, a fixing pin 4, a vertical positioning contact plate 6, and a rubber gasket 7. The drill bit 9 is installed. In the hand drill chuck 8, a tapered deep cavity fixed jacket 1 at the non-rotating position of the drill bit is placed outside the hand drill chuck 8, and the tapered deep cavity fixed jacket 1 and the elastic reset steel plate 3 pass through the fixed bolt 2 at the non-rotated position of the drill bit. Connection; elastic reset steel plate 3 and chassis fixing bracket 5 are connected by fixing pin 4; chassis fixing bracket 5 and vertical positioning contact plate 6 are welded together; vertical positioning contact plate 6 and rubber gasket 7 are bonded together,...

An elastic bending reset positioning device for drilling of a hand drill bit is a fixing device for assisting a user in centering the drilling perpendicular angle in the drilling process. According to the structure of the elastic bending reset positioning device, a hand drill chuck is sleeved with a drill bit non-rotation position conical deep cavity fixing clamping cover, and the drill bit non-rotation position conical deep cavity fixing clamping cover is connected with an elastic reset steel plate through a fixing bolt; the elastic reset steel plate and a bottom tray fixing support are connected through fixing pins; the bottom tray fixing support and a perpendicular positioning contact tray are welded together; and the perpendicular positioning contact tray and a rubber gasket are bonded together, and the perpendicular positioning contact tray is arranged on a plane to be drilled. By means of the elastic bending reset positioning device, the drilling depth and the perpendicularity are stably controlled, the operation of drilling is easy, the drilling precision is greatly improved, and the design requirement is met.
Description
technical field [0001] The invention relates to a fixing device for ensuring that the drill bit is perpendicular to the drilling plane when the hand-held drill bit is making holes, and preventing the holes from being skewed, cut off, inaccurate in position, out of tolerance and other problems caused by the jumping of the drill bit. Background technique [0002] At present, the hand-held drill bit only relies on the hand strength of the operator to control the direction, position and stability of the drill bit when making holes, and the relative force generated by the drill bit when making holes causes the drill bit to jump, run, slip, etc. A variety of problems; scratches on the working surface, gaps in the hole, serious hole diameter out of tolerance and other problems. Contents of the invention [0003] The object of the present invention is to provide an auxiliary device for assisting the user in finding the vertical angle of the drilling hole and controlling the drilli...
