Abstract

The invention relates to a spanner for engineering. The spanner comprises an annular control rack and a fixing plate. The annular control rack is fixedly connected with the fixing plate through at least one supporting strip. An orthohexagonal connecting column is arranged at the lower end of the fixing plate. A cavity of a hexagonal structure is formed in the orthohexagonal connecting column. A through hole is formed in the orthohexagonal connecting column. A bolt screwing head is arranged below the orthohexagonal connecting column. A connecting column, corresponding to the cavity, on the bolt screwing head is connected with the through hole through a bolt and a nut. The spanner is simple in structure and reasonable in design; as the orthohexagonal connecting column, the cavity and the bolt screwing head are arranged, the spanner can be suitable for bolts of different models, the bolt screwing head can be replaced according to actual requirements, the adaptability of the spanner is greatly improved, resources are saved, and use cost is reduced.

Description

A kind of engineering spanner
Technical field
The present invention relates to a kind of spanner, particularly relate to a kind of engineering spanner.
Background technology
Spanner is a kind of conventional installation and removal instrument.Utilize lever principle to twist bolt, screw, nut and other screw threads and tightly hold the opening of bolt or nut or the hand tools of trepanning firmware.Spanner is usually shaped with clamp holder portion and applies external force shank and apply external force in the one or both ends of shank, just can twist opening or trepanning that bolt or nut hold bolt or nut.During use, threadingly direction of rotation applies external force at shank, just can twist bolt or nut.The handle of a lot of type spanners used at present all into strips, can not turn bolt continuously in a lot of occasion, replacement operation position of must stopping, when the bolt quantity of degree of tightness is various, the operating efficiency of installation can be caused low, longer duration and more labour be expended.According to a kind of spanner that patent CN201609875U announces, although continuous print turn bolt can be realized, but generally can only carry out turn to the bolt of a certain model, when when the bolt of different model, just need a variety of this spanner, so just cause the waste of resource and the raising of use cost, and use also inconvenient.For the problems referred to above, a kind of technical scheme of solution is now proposed.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, providing a kind of engineering spanner.
The present invention is achieved through the following technical solutions:
A kind of engineering spanner, comprise annular control cage, fixed head, described annular control cage is fixedly connected with the support bar by least one between fixed head, described fixed head lower end is provided with regular hexagon joint pin, described regular hexagon joint pin inside is provided with the cavity of hexagonal structure, described regular hexagon joint pin is provided with through hole, is provided with bolt and twists head below described regular hexagon joint pin, and described bolt is twisted joint pin corresponding with cavity on head and is connected with through hole by bolt, nut.
As preferably, described regular hexagon joint pin is fixedly connected with fixed head.
As preferably, described bolt is twisted head and is also comprised regular hexagon bolt and twist head.
Compared with prior art, the invention has the beneficial effects as follows: structure of the present invention is simple, reasonable in design, head is twisted by arranging regular hexagon joint pin, cavity and bolt, the bolt of different model can be met, can change bolt according to actual needs twists head simultaneously, substantially increase the applicability of spanner, and save resource and use cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the above part-structure schematic diagram of regular hexagon joint pin in Fig. 1;
Fig. 3 is the top view in Fig. 2.
In figure: 1. annular control cage 1; 2. fixed head; 3. support bar; 4. regular hexagon joint pin; 5. cavity; 6. through hole; 7. bolt; 8. nut; 9. head twisted by bolt; 901. joint pin; Head twisted by 902. regular hexagon bolts.
Detailed description of the invention
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Refer to Fig. 1, Fig. 2 and Fig. 3, Fig. 1 is structural representation of the present invention, and Fig. 2 is the above part-structure schematic diagram of regular hexagon joint pin in Fig. 1, and Fig. 3 is the top view in Fig. 2.
A kind of engineering spanner, comprise annular control cage 1, fixed head 2, described annular control cage 1 is fixedly connected with the support bar 3 by least one between fixed head 2, described fixed head 2 lower end is provided with regular hexagon joint pin 4, described regular hexagon joint pin 4 inside is provided with the cavity 5 of hexagonal structure, described regular hexagon joint pin 4 is provided with through hole 6, stubborn 9, bolt is provided with below described regular hexagon joint pin 4, described bolt twists a joint pin 901 corresponding with cavity 5 on 9 by bolt 7, nut 8 is connected with through hole 6, this spanner can meet the bolt of different model, stubborn 9, bolt can be changed according to actual needs simultaneously, substantially increase the applicability of spanner, and saved resource and use cost.
Further, described regular hexagon joint pin 4 is fixedly connected with fixed head 2.
Further, stubborn 9, described bolt also comprises stubborn 902, regular hexagon bolt.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
