Description
Technical field
The utility model relates to a kind of fastening piece and hardware & tools, particularly a kind of anti-theft nut and special spanner.
Background technique
At present, some electrical equipment, as the ground hold-doun nut exposed of UT wire clamp, box type transformer, shaft tower and ground hold-doun nut etc., overhead setting height(from bottom) is lower, and screw, without anti-theft feature, uses wrench to screw out easily; Rural area is in order to cultivate convenient or lawless person's private, and these nuts easily suffer artificial destruction, thus affect the safe operation of power circuit equipment, cause the serious accident of falling rod disconnection sometimes, and then cause the serious consequence of personal injury or device damage.So, be badly in need of a kind of nut can with the ground electrical power equipment of simple anti-theft feature at present.
Summary of the invention
The purpose of this utility model is to provide a kind of anti-theft nut and special spanner of not easy-to-use common wrench dismounting, realizing the technological scheme that the purpose of this utility model takes is: a kind of anti-theft nut and special spanner, anti-theft nut includes nut body, internal thread is provided with in nut body, it is characterized in that: described nut body is cylindrical body, and the junction plane above the side of nut body and nut body is chamfer surface, nut body be relatively provided with four circular holes above; Correspondingly with anti-theft nut be provided with special spanner, described special spanner includes handle and sleeve, and relative four circular holes in side of sleeve are provided with four cylinders, cylinder and circular hole adaptive, cylinder can insert in circular hole.
Nut cannot screw off when not having special spanner by the utility model, when avoiding Panasonic's nut and the destruction problem produced.Ensure safe operation and the personal safety of circuit.
