Description

A Portable Universal Hole Reamer

technical field

The utility model relates to the field of cross-arm reaming tools for emergency repair of power systems, in particular to a portable general-purpose reamer.

Background technique

During the daily maintenance and emergency repair of power equipment and materials, it is often found that the apertures of copper-aluminum terminals, equipment clamps, and cross-arms do not match the site, and need to be processed and modified. For example, there are M16 and M18 screws for vertical bottles; The hole is generally only suitable for M16, and the upgrade of the rural power grid uses a large number of M18 vertical bottles and lightning protection insulators, and the vertical bottles and lightning protection insulators are replaced during emergency repairs.

Utility model content

The purpose of the utility model is to facilitate portability and hole reaming, and a portable universal hole reamer is specially provided.

The utility model provides a portable universal hole reamer, which is characterized in that: the portable universal hole reamer includes a booster wrench 1, a rotating lever 2, a reaming knife 3, a threaded rod 4, a spring 5, and a pin Positioning hole 6, positioning pin 7;

Among them: the lower ends of the two booster wrenches 1 are respectively hinged with the two ends of the rotary lever 2, and the two ends of the spring 5 are respectively connected with the upper end of the booster wrench 1 and the middle part of the rotary lever 2; the upper part of the threaded rod 4 has a thread, and the lower part has a cone Reaming knife 3; the top of threaded rod 4 has 1 to 5 pin positioning holes 6, arranged vertically and axially; threaded rod 4 is threaded with rotating lever 2; one end of positioning pin 7 is stuck in the groove of rotating lever 2 , and the other end is inserted into the pin positioning hole 6 on the threaded rod 4 .

The reaming knife 3 has 2 to 6 blades.

Advantage of the utility model:
