Abstract
The utility model relates to a spanner which can be used for wrenching worn screw bolts. The utility model is a spanner whose openings on both ends can work. One of both sides of the opening on one end is made into jagged, and the other side is a hooked edge which in the shape of the Chinese character 'liao' and is connected with a vaulted edge. One of both sides of the opening on the other end is in the shape of a straight line, and the other side is identical with the previous end side. The utility model is characterized in that the utility model not only can wrench normal screw bolts and wrench worn screw bolts firmly, but also brings convenience for repairing and assembly work.
Description
A kind of spanner of pulling the wearing and tearing bolt, it belongs to manual tool spanner field.
Existing known fork spanner is made generally in double end plane of the opening pattern, because easy to use being widely used in assembling and the repair work.But it exists when the bolt head of being pulled has worn and torn and is difficult for pulling, and causes the major defect that delays man-hour or shut-down.Thereby must repair by other instruments such as files and file out bolt head corner angle or moving with powerful tonger pincers.When the scene does not have other instruments and cooperates even cause at a loss what to doly, and brought worry to the mender.
The purpose of this utility model be disclose a kind of with wrench opening two planes, an end make the profile of tooth other end become the turning font solve that existing spanner can only be pulled normal bolt and the weak point that can not pull the bolt that worn and torn.
The utility model is realized in the following way.On the one end opening dual-side of spanner, minor face one side is a zigzag, have on the one side head of long limit length be the 1/2 following hexagon length of side the font limit, it is arcuation with the one side that is connected and constitutes 120 degree angles, the other end of spanner, minor face one side is made linear, and its long limit one side and an end are identical, and the base of spanner both ends open all connects and composes with circular arc.
The advantage that this utility model has is, it not only can pull normal bolt easily, and can firmly pull reliably by the bolt of heavy wear, and it also has the two-way characteristics of pulling the spanner work of needn't overturning.
Description of drawings:
The three-dimensional outline drawing of accompanying drawing 1 the utility model
Accompanying drawing 2 the utility model one end work partial schematic diagram
Accompanying drawing 3 the utility model other end work partial schematic diagrams
In conjunction with the accompanying drawings a kind of spanner of pulling the wearing and tearing bolt of the utility model is described further below by embodiment: it is the fork spanner of long handle double headed roller working end.On the opening bilateral symmetry limit of spanner one end 1, make zigzag 2 in minor face one side.The top of long limit one side is one and stretches out into 120 degree interior angles, the length of side be 1/2 below font limit 3, with to be connected one side be the arc limit 4 that is arcuation on the font limit.Minor face one side of the spanner other end 6 is made linear 7, and its another side is also made and an end 1 identical structure.The bottom surface of spanner two work openings ends all connects moulding with the circular arc limit.As shown in Figure 2, it is with zigzag 2 arcuation arc limits 4 when its wrenching bolt, three operating points of the inwardly curved state that peak and long limit 3 form, tighten to be pulled normally or the bolt head that has worn and torn pull.It fixes fastening firm.Can screw easily or bolt that Panasonic is pulled.
