Abstract
The utility model discloses a root nut wrench which comprises a steel tube handle. The root nut wrench is characterized in that the root nut wrench also comprises a normal opening nut sleeve, an eccentric opening nut sleeve and a boosting rod, wherein the normal opening nut sleeve and the eccentric opening nut sleeve are arranged at the two ends of the steel tube handle after 1/2 to 2/3 of tube walls at the two ends are cut, and are vertical to the central line of a steel tube; and the boosting rod is movably inserted in a boosting rod hole on the steel tube handle. The root nut wrench of the structure has the following advantages: the root nut wrench can fasten the root nuts directly and conveniently without dismantling any nut, gasket or electric connector on connector posts; the torsion stroke angle is big and the torsion stroke angle of the eccentric opening nut sleeve is especially bigger; and the root nut wrench does not rub the adjacent connector posts, has simple and practical structure, can improve the work efficiency greatly and is a good helper with mechanical and electric appliance maintenance. The root nut wrench is applicable to bolts and terminal blocks with a plurality of nuts.
Description
Technical field
The utility model relates to a kind of hand-operated tools, in particular for the spanner of nutting.
Background technology
In the installation and maintenance work of being engaged in electrical equipment, usually run on a plurality of nut bolt binding posts, all accompany fixing cord between per two nuts.Becoming flexible, being shifted all can appear in this binding post in use for some time, causes the loose contact between binding post and the lead, and it is bad that electric conductivity becomes.Cause contact resistance to increase, phenomenons such as heating, sparking occur, fastening as untimely inspection, will influence the operate as normal of circuit, even cause major accident.Therefore, the maintenance personal will regularly check, terminal operation.
At present there is not a better instrument to the root nut of a plurality of nut bolt binding posts is fastening, have only the common wrench of use that each nut, pad, lead on the stud terminal are backed out one by one, could be with common wrench with the root nut screwing clamping, another ground is again with pad at last, nut, lead, top nut are fastening, and operational sequence is cumbersome time-consuming like this, and work efficiency is low, and repair quality is difficult to guarantee, can makes electrical equipment stay potential faults.In practice, the nut fixing cord of twisting this binding post with common nut spanner is difficult, and the nut of especially twisting root is difficult especially, and operating efficiency is very low.
Summary of the invention
The purpose of this utility model provides a kind of root nut spanner, can twist the root nut of a plurality of nut bolts easily, increases work efficiency.
In order to realize above-mentioned purpose, the technical solution of the utility model is:
A kind of root nut spanner, it comprises the steel pipe handle, it is characterized in that also comprising:
On the termination after 1/2～2/3 1 section tube wall is pruned at described steel pipe handle two ends, vertical mutually with the steel pipe center line, the positive opening nut sleeve that an end is provided with, the eccentric openings nut sleeve that the other end is provided with;
Activity is inserted in the boosting-rod in the described steel pipe handle boosting-rod hole.
Described eccentric openings nut sleeve, its center line and steel pipe handle decentraction, and also the opening dual-side of opening nut sleeve is asymmetric, on one side big, another side is little.
The root nut spanner advantage of above structure is: need not dismantle any nut, pad and electrical wiring on the binding post, just can directly He easily carry out fastening to the root nut, and the stroke angles of reversing is big, and especially the stroke angles reversed of eccentric openings nut sleeve is bigger, stressing conditions is better.Not can with contiguous binding post grazing, simple and practical, time saving and energy saving.Can improve work efficiency widely, be the good assistant of machinery, electrical repair.

In the drawings, positive opening nut sleeve 1, anode tube seat 2, steel pipe handle 3, boosting-rod 4, boosting-rod hole 5, eccentric end tube seat 6, eccentric openings nut sleeve 7, insulation spacer 8, installing plate 9, bolt binding post 10, top nut 11, root nut 12.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 and Fig. 2 are that master of the present utility model looks and the plan structure schematic diagram.As we know from the figure, vertical mutually on the termination after 1/2～2/3 1 section tube wall is pruned at the two ends of steel pipe handle 3 with steel pipe handle 3 center lines, the positive opening nut sleeve 1 that an end is provided with, the eccentric openings nut sleeve 7 that the other end is provided with; In the boosting-rod hole 5 of steel pipe handle 3, activity is inserted with boosting-rod 4.Pruning and be fixed with respectively behind 1/2～2/3 1 section tube wall and steel pipe center line or the orthogonal positive opening nut sleeve 1 of tube wall, eccentric openings nut sleeve 7 in the two ends of steel pipe handle 3, and constitutes anode tube seats 2, eccentric end tube seat 6 with positive opening nut sleeve 1, the eccentric openings nut sleeve 7 of two ends.Tube seat 2,6 is used to allow between the upper and lower nut fixing lead, conveniently twists nut.
Fig. 3 and shown in Figure 4 is the left and right TV structure schematic diagram of Fig. 1.Can see by Fig. 3, positive center line of opening nut sleeve 1 and overlapping substantially of steel pipe handle 3, and, the opening both sides left-right symmetry of nut sleeve 1; Can see that from Fig. 4 the center line of eccentric openings nut sleeve 7 does not overlap with steel pipe handle 3, the deflection left side; And the left and right sides, opening both sides of nut sleeve 7 is asymmetric, and the left side is big, and the right is little.The stroke angles that eccentric openings nut sleeve 7 is reversed is bigger than nut sleeve 1.
Shown in Figure 5, be three-dimensional work schematic diagram of the present utility model.In the drawings, bolt binding post 10 is fixed on the installing plate 9 by top nut 11, root nut 12 and insulation spacer 8.Can see that from figure the eccentric openings nut sleeve 7 of the utility model root nut spanner one end is enclosed within on the root nut 12 from a side, is easy to turn root nut 12 by the boosting-rod on the steel pipe handle 34.Obviously, also can turn top nut 11 easily.
