Multi-diameter non-adjustable spanner with internal-tooth skid-resistant function

Abstract

The invention relates to a multi-diameter non-adjustable spanner with an internal-tooth skid-resistant function. Saw teeth (2) in a row are machined on the inner side of a non-adjustable spanner (1), and then inner hexagonal holes (2) in a row are drilled on a handle (3), thus, a manual spanner with a skid-resistant function and a function of loosening multi-diameter screws is formed and can take the place of a conventional non-adjustable spanner.

Description

Technical field [0001] The invention relates to a multi-diameter fixed wrench with anti-slip function of internal teeth. The handle of the fixed wrench is provided with a plurality of inner hexagonal holes, and a row is discharged. A multi-diameter wrench with anti-slip function. Background technique [0002] Ordinary fixed wrench can only be used to wrench one kind of hexagonal nut, so to complete a job, it is necessary to equip multiple wrenches, which may bring a lot of trouble to the work, so we drill a row of hexagonal holes on the fixed wrench, so that A single wrench can pull multiple diameter hexagon screws, and multiple diameter manual wrenches. SUMMARY OF THE INVENTION [0003] The principle of the invention is to process a row of serrations on the inner side of a fixed wrench, and at the same time, open a plurality of hexagonal holes on the handle, and also make it discharge a row, so that it becomes a wrench with anti-slip function and can open multi-diameter ...
