Abstract

A field multi-use tool structure including Ad multiple tools. An illuminating unit is disposed in the grip. The front end of the grip has a tool connecting section formed with a central socket axially rearward extending from front end thereof. One side of the tool connecting section is formed with a front and a rear radial through holes communicating with the socket. A locating pin and an engaging pin are respectively passed through the front and rear through holes. The engaging pin has a large diameter section and a small diameter section. A spring is fitted around the small diameter section. One end of each of the tools is formed with a working section with different functions, while the other end of the tool is formed with a fitting section formed with a locating split for fitting with the locating pin and the small diameter section of the engaging pin. The locating split is formed with an enlarged engaging bore corresponding to the engaging pin for the large diameter section thereof to fit into the engaging bore. The locating pin and engaging pin of the tool connecting section of the grip can respectively extend into the locating split and engaging bore of the fitting section of the tool so as to fix the tool with the grip. Therefore, different kinds of tools can be easily connected with one single grip to facilitate carriage of the tools. In addition, the illuminating unit in the grip provides necessary illumination for working in dark places.

Claims

1. A field multi-use tool structure comprising:

a grip, at least front end of the grip being made of transparent material, an illuminating unit being disposed in the grip, the illuminating unit including a light emitting member, a set of cells and a switch disposed on rear end face of the grip, a front end of the grip having a tool connecting section formed with a central socket axially rearward extending from front end thereof, one side of the tool connecting section being formed with a front and a rear radial through-holes communicating with the socket, the opening of each end of each through hole being formed with a fish-eye hole with larger inner diameter, a locating pin being passed through the front through hole, each end of the locating pin being formed with a head section with larger outer diameter corresponding to the fish-eye hole, an engaging pin being passed through the rear through hole, the engaging pin having a length larger than that of the locating pin, each end of the engaging pin being formed with a head section with larger outer diameter for fitting into the fish-eye hole, the engaging pin having a large diameter section and a small diameter section, a spring being fitted around the small diameter section, two ends of the spring respectively abutting against the bottom of the fish-eye hole and the head section of the engaging pin; and

multiple tools, one end of each of the tools being formed with a working section with different functions, the other end of the tool being formed with a fitting section for inserting into the socket of the tool connecting section, the fitting section being formed with a locating split having an opening at one end distal from the working section, the locating split being snugly fitted with the locating pin and the small diameter section of the engaging pin, the locating split being formed with an enlarged engaging bore corresponding to the engaging pin for the large diameter section thereof to fit in.

2. A field multi-use tool structure as claimed in claim 1, wherein a connecting section is disposed on one side of the rear end of the grip for pivotally connecting with a rear cap, a compass being disposed in the rear cap, a hook section being formed on one side of the rear cap opposite to a pivot section thereof, the grip being formed with a dent corresponding to the hook section of the rear cap for latching with the hook section when closing the rear cap.
