Internal and external hexagonal dual-purpose screwdriver

Abstract

The invention belongs to the technical field of mechanical tools, and particularly relates to an internal and external hexagonal dual-purpose screwdriver. The internal and external hexagonal dual-purpose screwdriver comprises a screwdriver head, the screwdriver head is of a cylindrical structure, a hexagonal hole groove is formed in the center of the screwdriver head in a penetrating mode, a hexagonal column is connected into the hexagonal hole groove in an inserted and embedded mode, and one end of the screwdriver head is fixedly connected with a connecting frame. According to the internal and external hexagonal dual-purpose screwdriver, the hexagonal hole groove is formed in the center of the screwdriver head in a penetrating mode, the hexagonal column is connected into the hexagonal hole groove in an inserted and embedded mode, a limiting plate is fixedly welded to the top of the hexagonal column, two threaded pin holes are formed in the outer side surface of the hexagonal column, athreaded pin column is connected to the outer side surface of the screwdriver head through threads, and the threaded pin column is matched with the threaded pin holes in position and structure; and by means of the structure, an inner hexagonal screwdriver and an outer hexagonal screwdriver are combined into a whole, the use requirements of a user are met to a great extent, the number of tools carried by the user in the working process is reduced to a certain extent, and the use requirements are met.

Description

technical field [0001] The invention belongs to the technical field of mechanical tools, and in particular relates to a dual-purpose screwdriver with internal and external hexagons. Background technique [0002] The inner hexagonal screwdriver and the outer hexagonal screwdriver are commonly used workpieces in the process of installing and disassembling mechanical parts. Most of the existing two screwdrivers are set independently, and they need to be used separately for the bolts during use, so that the number of tools carried by the user is relatively small. Many, cause certain troubles to the user, and the connecting rod of existing hexagonal screwdriver and external hexagonal screwdriver is all fixed length simultaneously, can't adjust the length of connecting rod according to the use space, also causes certain troubles to the user. Contents of the invention [0003] In order to solve the problems raised in the background technology above, the present invention provides...
