Description

one

The invention relates to magic build-up, namely, hand tools used to work in ore accessible places.

The purpose of the invention is to increase reliability when working in hard-to-reach places, due to the operator receiving information about the seizure by an organ of the work object.

Fig. 1 shows a hand tool, a general view, in section; FIG. 2 is the same, with a fastener disposed therein; in fig. 3 is a section A-A in FIG. 2.

The hand tool contains a hollow handle 1, a light source in the form of an incandescent lamp 2, a power source 3, a power supply device 4, a protective transparent partition 5, a working body 6 in the form of a socket wrench. In the working body 6, intersecting axial 7 and radial 8 holes are made, In axial holes 7, stepped rods 9 are placed, spring-loaded axially to handle 1 with an elastic element 10, the diameter of the larger step of each rod 9 is not less than the diameter of the radial hole 8, and the diameter of the smaller step of each rod 9 is smaller than the diameter of the radial hole 8. Outside, the radial holes 8 are covered with glass 11.

Hand tools works as follows.

By means of the - device 4, the incandescent lamp 2 is switched on, the light from which propagates to the work object, for example the nut 12, located in the body

lighted place. The radial holes 8 at this time are blocked by a step of a larger diameter of the rod 9, and the light does not come out through the radial holes 8.

Then the working body 6 is put on the nut 12, which tends to sink the rods 9, overcoming the resistance of the elastic element 10. The streams of light, partially delayed by steps of smaller diameter of the rods 9, go out through the panes 11, indicating that the guidance is complete and the nut 12 is inside the working body 6. After that, the light can be turned off and the tool unscrews the nut 12,
