Special socket for tap

Abstract

The invention relates to a sleeve special for a screw tap. The sleeve comprises a rod-shaped body, one end of the rod-shaped body serves as a fixing end, the other end of the rod-shaped body serves as a clamping end, and the fixing end is shaped like a regular hexahedron; the end face of the clamping end is provided with installing holes, and the installing holes comprise a first fixing hole and a second fixing hole which are both square holes and are formed along the axis of the rod-shaped body. By means of the structure, the screw tap can be conveniently used on automatic drilling equipment such as electric guns and air guns, and the requirement for using two screw taps with different sizes can be met; more auxiliary devices are not needed, the drilling equipment such as the electric guns and air guns which are used at original stations does not need to be replaced, the equipment utilization rate is increased, convenience of an operator is effectively improved, and higher production efficiency is achieved.

Description

technical field [0001] The invention relates to a drilling tool, in particular to a special sleeve for taps. Background technique [0002] At present, the taps on the market are all machine taps and hand taps that require a tap wrench. The special connecting device is adopted, so that the tap can be installed on the drilling equipment. For this reason, some inventors have proposed various improved technologies, such as the disclosed technology named "Socket Wrench Function Expansion Accessory" (authorized announcement number: CN2150971Y), which uses a set of socket wrench specifications that match Different function expansion sockets and rods to meet the needs of fastening and disassembly of fastening connectors with inner and outer hexagonal, slotted and cross-headed parts, as well as tapping and reaming with square heads; but this There are some deficiencies in the disclosed technology, such as many parts and low efficiency, which is not convenient for the application of...
