Description

Special electric hand drill for processing marine evacuation system channel

Technical Field

The patent of the utility model relates to an electric tool field, especially a special electric hand drill of system's passageway processing withdraws at sea.

Background

A marine evacuation system is arranged during marine operation, the marine evacuation system comprises a passage and a corresponding shaping device, and an electric hand drill is mainly used for fixing the passage in the marine evacuation system on a metal frame of the shaping device.

When the existing electric hand drill drills on metal, even if a small pit is punched at a designated position on the surface of the metal by a punch, the phenomena of incorrect hole position and sliding of a drill bit to the side edge can be generated during drilling, so that the position of the drilled hole is not a pre-marked position, and even the injury of people or objects is caused.

Disclosure of Invention

In order to solve the problems, the utility model provides a special electric hand drill for processing the marine evacuation system channel, which comprises an electric drill body, a drill bit and a detachable fixing device arranged at the upper end of the drill bit,

the fixing device comprises a fixing piece, a fixing block, a rack, a gear, a mounting shaft, a driving handle and an L-shaped metal strip; the mounting sets up the one side that is close to the electric drill body at the drill bit, the mounting upper end is provided with the fixed block, the fixed block with the mounting by bolt fixed connection, the lower extreme is provided with the rack in the fixed block, the upper end is provided with the gear in the fixed block, the gear is installed through the installation axle the fixed block upper end, the gear with rack toothing, just the gear with the installation synchronous rotation of axle still be provided with actuating handle on the fixed block, actuating handle with installation axle fixed connection, "L" type metal strip welding is in the rack lower extreme, length direction with drill bit length direction is the same.

Further, the fixing piece is fixedly arranged on the drill bit through a bolt.

Further, the fixed block and the fixing piece are fixedly connected through the bolt.

Further, the diameter of the drill bit is 4.2-6.5 mm.

The utility model has the advantages that:

1. the gear and the rack are meshed to drive the L-shaped metal strip to move, and the distance between the L-shaped metal strip and the drill bit is adjusted to adapt to drilling on metals with different diameters by the electric hand drill.

2. The L-shaped metal strip is connected with the drill bit, so that the position of the drilled hole can be fixed without sideslip or movement.

A special electric hand drill of system's passageway processing is withdrawn at sea, can fix the drilling position and prevent that the drill bit from sideslipping when drilling, can avoid causing the injury to people or thing when sideslipping. During operation, the fixing device can fix the positions of the drill bit and the metal frame well, and the handle fixed on the gear in a rotating mode can enable the gear and the rack to move relatively, so that labor is saved, convenience is brought, and operating personnel are reduced.
