Five jiaos of special spanners in a kind of
Technical field
The utility model belongs to the fastener tool field, particularly relates to interior five jiaos of spanners that shape five-cornuted bolt uses or other similar interior five corner bolts use in a kind of profile hexagonal.
Background technology
In traditional mechanized equipment industry, the bolt in the securing member is common part commonly used, particularly outer-hexagonal bolt, and use amount proportion is bigger; But in today that mechanized equipment makes rapid progress, often the General fasteners bolt can not satisfy the needs of present many occasions, and especially in some more special equipment occasions, the effect of General fasteners bolt is very limited especially; Particularly common bolt, by common spanner, be worn easily and cause fillet through its outer-hexagonal after repeatedly the dismounting, cause bolt normally to use, cause some equipment configurations all can't carry out dismounting and unload, bring great inconvenience to real work; Sometimes just can deal with problems later at destruction bolt or structure even, the damage of bolt brings great inconvenience for dismounting, maintenance and debugging work through regular meeting; The applying unit of bolt often will be changed bolt and will destroy equipment, can cause product cost to increase undoubtedly and not guilty waste.
The utility model content
Technical problem to be solved in the utility model provides a kind of interior five jiaos of special spanners, to remedy in the prior art, use after common wrench and the special sleeve spanner, dismantle replenishing of interior five corner bolts of a kind of outer-hexagonal, and other similar bolt dismantles, solve use several instruments can dismantle in the mechanized equipment special in the Complementarity Problem of five corner bolts.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of interior five jiaos of special spanners are provided, comprise main body, described body cross-section is a regular pentagon.
Described main body is L-shaped, its front end 90 degree bendings.
Beneficial effect
Five jiaos of special spanners in the utility model is special, making full use of spanner is five-cornuted, thereby the effect of demounting bolt is increased greatly, though special bolts can use common and special-purpose spanner, sleeve to dismantle, but be to use a kind of special interior five jiaos of special spanners to dismantle, also may produce the effect of getting twice the result with half the effort in certain occasion, can be used as a kind of method and actively remedy.
Description of drawings
Fig. 1 is five jiaos of special spanner schematic diagrames in the utility model.
The specific embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only to be used to the utility model is described and be not used in the restriction scope of the present utility model.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
Embodiment 1
As shown in Figure 1, a kind of interior five jiaos of special spanners comprise main body 1, and described main body 1 cross section is a regular pentagon.
The 90 degree bendings of described main body 1 front end are L-shaped.
Five jiaos of spanners in a kind of, interior five jiaos of spanners in many cases, with the use that can develop simultaneously of other extracting tool, more can use separately, and when other instrument can not play a role, interior five jiaos of spanners more can be brought into play its positive effect, can carry out the dismounting of special bolts.
The use of five jiaos of spanners in a kind of has been accustomed to the inner hexagon spanner that uses as us, and the user is as long as aim at spanner on the bolt head recessed five jiaos, and the user just can carry out the dismounting and the installation of special bolts easily then.
So, in special bolts or other this type of bolt have had, after five jiaos of spanners, just carry out the dismounting of bolt more easily, thereby improved operating efficiency, saved valuable time, some unnecessary destructions also can be avoided fully.
