Abstract

The utility model belongs to a ball-shaped jaw sealing pliers, which is composed of a pliers handle, a pliers head, a pressing handle, a shaft and a spring. The sealing pliers is characterized in that a transverse hole is arranged on the front end part of the pliers handle. The gap in the transverse hole is matched with an upper mould which is fixed by a screw, and a hole is arranged in the slot of the pliers and is correspond to the upper mould; the gap in the transverse hole is matched with a lower mould which is fixed by a screw, and the inners of the upper mould and the lower mould are in the form of a semi-sphere. The sealing pliers is suitable for ball-shaped lead sealing balls, the pressed sealing balls has regular and smooth surface and clear characters. The sealing pliers can effectively prevent artificial meter moving and electricity stealing and is a ball-shaped lead sealing special pliers of electricity industry, tap water industry and other meters.

Description

Spherical jaws envelope pincers

The utility model relates to lead sealing pliers, is the special-purpose spherical jaws envelope of a kind of instrument lead sealing pincers.

At present, the instrument lead sealing all is to adopt oblate or cylindrical blocking, with envelope pincers be by pincers handle, pressure handle, binding clip, spring and spool constitute, this pincers jaw is plane or convex surface, be provided with character above, the lead sealing ball profile of extrusion is irregular, and thin and thick, height differ, if there is the artificial table that moves also to be difficult for finding, causing the people easily is that stealing falls to show.

The purpose of this utility model provides a kind of spherical jaws and seals pincers, and irregular with the blocking profile that solves the extrusion of existing envelope pincers, thin and thick, height differ, and artificial moving table is difficult finds that easily causing the people is the stealing problem of falling the table.

The purpose of this utility model is achieved in that this envelope pincers are made up of pincers handle, pressure handle, binding clip, axle and spring, pincers are provided with transverse holes to leading section, the hole internal clearance is combined with mold, fix by screw, be provided with the hole with the mold corresponding section in the binding clip groove, the hole internal clearance is combined with bed die, fixes by screw.

Mould has two up and down, is convex shape, and top is thick outer cylindrical, in be hemispherical, character is arranged at the end, the bottom carefully is cylinder or stupefied cylindricality.

This utility model compared with prior art has the following advantages: 1) use spherical lead sealing ball, the blocking surface of extrusion is regular bright and clean, and character is clear, can effectively prevent the stealing of artificial moving table; 2) mould is changed conveniently by screw is fixing.

Be described further below in conjunction with accompanying drawing
