Abstract

The invention belongs to the technical field of drilling tools, and specifically discloses a pistol drill facilitating accurate location. The pistol drill facilitating accurate location comprises a machine body and a drill bit, wherein three slide rods are arranged in the circumferential direction of the machine body; a sealed accommodating shell is arranged in the circumferential direction of themachine body; first piston barrels and a second piston barrel are arranged in the accommodating shell; the capacity of the second piston barrel is equal to the sum of the capacities of all the firstpiston barrels; a first piston is arranged in each first piston barrel; each first piston is fixedly connected with the corresponding slide rod; an intake pipe is communicated to each first piston barrel; all the intake pipes communicate with the second piston barrel; a second piston is arranged in the second piston barrel; a piston rod is arranged on the second piston; an induction mechanism is further arranged in the accommodating shell; the induction mechanism comprises a positive plate and a negative plate; the positive plate is fixedly connected with the piston rod; and the distance between the positive plate and the negative plate is equal to the length of the second piston barrel. According to the scheme, the problem that the drill bit is liable to be inserted slantwise into a workpiece during the drilling of operating personnel, is solved.

Description

Technical field [0001] The invention belongs to the technical field of drilling tools, and specifically discloses a pistol drill convenient for accurate positioning. Background technique [0002] Pistol drill, also known as electric hand drill, is a tool for drilling holes in metal materials, wood, and plastics. It can be used as an electric screwdriver when equipped with the first switch for forward and reverse rotation and an electronic speed regulating device. Some models are equipped with rechargeable batteries, which can work normally for a certain period of time without external power supply. At present, pistol drills commonly used in the market include drill bits, drill shafts, fuselages, first switches, motors and so on. When the operator uses a pistol drill to drill, he usually draws the position of the pre-drilled hole on the workpiece to be processed, and then holds the pistol drill to drill, but in this process, if the operator does not operate properly, it will cau...
