Problems solved by technology

[0002] Air-conditioning holes, range hood holes, water supply and drainage pipes etc. are all to be drilled with a long tubular portable water drill drilling machine, and the drill bit of the existing portable water drill drilling machine and the mounting head of the drilling machine are only If the screw thread is used for screw installation, since the drill bit is rotating at a high speed when the drilling machine is working, it will cause excessive engagement of the threaded part connecting the drill bit and the installation head. The problem of cracking due to over-engagement, cracking will cause the drill bit to break, and it may also cause the drill bit to be thrown out, and the operation risk factor is high

Abstract

The invention discloses a portable drilling machine. The portable drilling machine structurally comprises a drill bit, a mounting head, an auxiliary handle, a machine body, a shoulder rest, a main handle and a water inlet pipe, wherein one end of the machine body is connected with the mounting head; the drill bit is mounted on the mounting head; and the other end of the machine body is connected with the shoulder rest. Compared with the prior art, the portable drilling machine has the beneficial effects that the drill bit and the mounting head are preliminarily fixedly connected through threads, a clamping block is pressed by a first spring to be matched with a clamping groove, then the drill bit is limited and fixed again and is effectively prevented from rotating slightly to be excessively engaged with the mounting head, the drill bit is prevented from cracking and being thrown out, and the operation safety coefficient can be improved; and a second spring is used for pressing a liquid storage bag so that cooling liquid can further generate pressure on the clamping block to prevent the clamping block from shrinking inwards, thus, the clamping firmness of the clamping block and theclamping groove can be further improved, the mounting stability of the drill bit and the mounting head can be greatly improved, and the drilling quality is favorably improved.

Description

technical field [0001] The invention relates to the technical field of automatic special machines, in particular to a portable drilling machine. Background technique [0002] Air-conditioning holes, range hood holes, water supply and drainage pipes etc. are all to be drilled with a long tubular portable water drill drilling machine, and the drill bit of the existing portable water drill drilling machine and the mounting head of the drilling machine are only If the screw thread is used for screw installation, since the drill bit is rotating at a high speed when the drilling machine is working, it will cause excessive engagement of the threaded part connecting the drill bit and the installation head. The problem of cracking caused by excessive meshing will cause the drill bit to break, and it may also cause the drill bit to be thrown out, and the operation risk factor is high. Contents of the invention [0003] The main purpose of the present invention is to overcome the de...
