Referring to fig. 1-3, the present invention provides a technical solution: the utility model provides a perforator for building, which comprises a main body, the main part includes unable adjustment base 9, the pulley is installed to unable adjustment base 9's bottom, all install stop gear on the wall of both sides around unable adjustment base 9, stop gear includes fixed part 8 and height-adjustable pipe box 7, fixed part 8 and unable adjustment base 9's lateral wall fixed connection, height-adjustable pipe box 7 inserts the inside of locating fixed part 8, limiting plate 13 is installed at height-adjustable pipe box 7's top, fixed part 8 is kept away from the one end of unable adjustment base 9 and is installed stop bolt 11, stop bolt 11's outside cover is equipped with and is tightened up spring 10, unable adjustment base 9 has been seted up to height-adjustable pipe box 7 and stop bolt 11's terminal corresponding position department, and stop bolt 11's end has.

In this embodiment, preferably, an inner limit post 14 is inserted into the height-adjustable pipe sleeve 7, an expansion spring 12 is installed in the height-adjustable pipe sleeve 7 and at the top end of the inner limit post 14, and an anti-skid plate with anti-skid protrusions on the ground is installed on the bottom surface of the inner limit post 14.

In this embodiment, preferably, one end of tightening spring 10 is fixedly connected to limit bolt 11, and the other end of tightening spring 10 is fixedly connected to fixing portion 8.

In this embodiment, preferably, the outer surface of the limiting bolt 11 is provided with anti-slip lines.

In this embodiment, preferably, the main part still includes lifter 1, motor 3, gear box 4, light 5 and drill bit 6, and lifter 1 is installed at the top of unable adjustment base 9, installs on the lifter 1 can be along the gliding gear box 4 from top to bottom of lifter 1, installs height control swing arm 2 on the lateral wall of gear box 4, and motor 3 is installed at the top of gear box 4, and the drill bit 6 of being connected with the output of motor 3 is installed to the bottom of gear box 4.

The utility model discloses a theory of operation and use flow: when the device is used, the motor 3 drives the drill bit 6 to rotate, and meanwhile, the height of the gear box 4 is reduced until the drill bit 6 is contacted with concrete, so that drilling can be carried out;

because the fixed base 9 adopts the pulley to facilitate the device to move, when the device does not need to move, the limiting plate 13 is pressed by feet, and because the inclined plane design of the fixed base 9 and the tail end of the limiting bolt 11, the height-adjustable pipe sleeve 7 can move downwards until the antiskid plate at the bottom of the inner limiting column 14 is contacted with the ground, so that the side friction force between the antiskid plate and the ground can be increased, and the limiting of the device is facilitated;

if continue to push down height-adjustable pipe box 7, expanding spring 12 receives the extrusion and the shrink of limiting plate 13, spacing post 14 in the elasticity of expanding spring 12 pushes down for the antiskid ribbed tile and the ground in spacing post 14 bottom in close contact with, thereby further increased frictional force, further increased stability, when need not use and spacing the device, outside pulling stop bolt 11, until the end of stop bolt 11 no longer contacts with unable adjustment base 9, can be with height-adjustable pipe box 7 rebound, until antiskid ribbed tile and ground no longer contact, can the mobile device.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
