Embodiment 1

[0031] Example 1 as figure 1 Shown, a kind of gun drill with drill conversion device comprises, gun drill main body 1, the motor, wire, switch, gear reduction mechanism (not drawn) that are arranged in gun drill main body 1, and its power supply is figure 1 The lower part of the battery pack; it is characterized in that a drill conversion device is provided at the front and bottom of the gun drill, and the drill conversion device includes: a telescopic positioning mechanism; a center positioning mechanism and a drilling conversion mechanism.

[0032] Telescopic positioning mechanism:

[0033] Mainly by placing the telescopic positioning bracket 9, the telescopic positioning bracket seat 11 arranged on the edge of the front and lower shell of the gun drill main body 1, one end is placed in the telescopic positioning bracket seat 11, and the other end is provided with a slope 904 for turning the telescopic positioning bracket The telescopic positioning support 9 and the locking...

Embodiment 2

[0045] Embodiment 2 is an AC electric gun drill with a drill conversion device, so no battery pack is required. The inclined plane 904 on which the telescopic positioning bracket is turned turns upwards, but it can also be designed to turn downwards. The groove 903 in the telescopic positioning bracket 9 can also be arranged in the middle or side of the telescopic positioning bracket 9 . The rest of the structure of the drilling tool conversion device is the same as that of Embodiment 1, and its functions are also basically the same. In contrast, embodiment 1 does not have the trouble of pulling the power cord, so it is more suitable for use in high-altitude operations.

Abstract

The invention relates to an electric gun drill, in particular to a gun drill with a conversion device of a drilling tool, and comprises a gun drill main body, an electric motor, a wire, a switch and agear reducing mechanism. The invention is characterized in that: the conversion device of the drilling tool is arranged at the front and lower of the gun drill. The conversion device of the drillingtool comprises a telescopic positioning bracket base arranged front and lower to the gun drill, a telescopic positioning bracket base, one end of which is inserted into the telescopic positioning bracket base and the other end is provided with an inclined plane for the telescopic positioning bracket to turn back and a telescopic positioning mechanism that consists of a locking handle arranged at the middle part of the telescopic positioning bracket, a drilling tool conversion mechanism that consists of a swinging strut arranged on the inclined plane for the telescopic positioning bracket to turn back and is provided with two or more drilling tool installing holes and a drilling tool arranged in a hanging way on the drilling tool installing holes of the swinging strut and the rear end of which is capable of being connected with a principal axle of the gun drill, and a center positioning mechanism that consists of mainly a center positioning board fixed on the end face of the front end of the gun drill and matched with the end part of the swinging strut. The invention can reach a purpose of changing a drill bit without withdrawing a drill bit.

Description

technical field [0001] The invention relates to an electric gun drill. In particular, it is a gun drill with a drill conversion device, which is realized by rotating the drill conversion device without removing the drill bit on the gun drill to complete the replacement of the drill bit. Background technique [0002] The head of the electric gun drill is equipped with a drill bit, and it is very convenient for people to make a hole. Therefore, the electric gun drill is very popular. But now, the electric gun drill can only install one drill bit on the main shaft of the gun drill. During use, drill bits of different specifications are often used, and one drill bit cannot meet the needs of use. Therefore, in operation, the drill bit of the electric gun drill is often replaced. Just have to disassemble and clamp again whenever exchanging drill bit, bring a lot of troubles to operation. Especially when working at high altitude, the situation that the drill bit is dropped due ...
