Abstract
The utility model discloses a lengthened sleeve of a universal inner hexagon spanner, which includes a lengthened rod (1), wherein a connecting hole corresponding to the inner hexagon spanner (6) is formed at the bottom of the lengthened rod (1); threads (8) are arranged on an excircle at the lower part of the lengthened rod (1); a lock nut (5) is arranged on the threads (8); a rectangular hole (2) and a handle hole (4) are formed at the top of the lengthened rod (1); and a handle (3) is arranged in the handle hole (4). Compared with the ordinary lengthened sleeve which is only applicable to the inner hexagon screw of one specification, the lengthened sleeve of the universal inner hexagon spanner is applicable to the mounting/dismounting of the inner hexagon screws of certain specifications through the lock nut and the elastic groove on the lengthened sleeve. The lengthened sleeve of the universal inner hexagon spanner also retains the function of the existing lengthened sleeve, and can solve the problem that the screw can't be mounted/dismounted due to over-deep position or over-narrow space.
Description
Technical field
the utility model relates to a kind of general inner hexagon spanner lengthening cover, belongs to the grinder buffing technical field of tools.
Background technology
The standard soket head cap screw spanner that
electromechanical industries are commonly used; During use through regular meeting too dark or locus is narrow because of screw position can't knockout screw; If there is the lengthening cover also to exist different spanners need use the problem of different lengthening covers; Extremely inconvenient, operation is wasted time and energy, inefficiency.
Summary of the invention
The purpose of
the utility model is, a kind of general inner hexagon spanner lengthening cover is provided.Not only can solve the narrow problem that can't knockout screw in because of screw position too dark or locus, and can general within the specific limits one the lengthening cover.
The technical scheme of the utility model
a kind of general inner hexagon spanner lengthening cover comprises extension bar, and the extension bar bottom is provided with and the corresponding connecting hole of inner hexagon spanner, and the cylindrical of extension bar bottom is provided with screw thread, and screw thread is provided with locking nut; The extension bar top is provided with rectangular opening and handle hole, is provided with handle in the handle hole.
In
aforesaid general inner hexagon spanner lengthening cover, the screw thread place on the cylindrical of said extension bar bottom is provided with elastic groove.
In
aforesaid general inner hexagon spanner lengthening cover, said locking nut epimere is cylindric, and the hypomere of locking nut is the awl tubular, and interior circle cylindraceous is provided with screw thread.
compared with prior art; The utility model is different from common lengthening cover; Common lengthening cover is the only soket head cap screw of a specification of a lengthening cover, and a lengthening cover of the utility model can make the lengthening cover of the utility model be applicable to the loading and unloading of the hex screw of certain specification scope through locking nut and the elastic groove that lengthening puts.But also kept the effect that existing lengthening overlaps, can install and remove the too dark or narrow problem that can't load and unload in locus because of screw position.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the partial enlarged drawing of Fig. 1.
Being labeled as in
accompanying drawing: the 1-extension bar, the 2-rectangular opening, the 3-handle, the 4-handle hole, the 5-locking nut, the 6-inner hexagon spanner, 7-bores tubular, 8-screw thread, 9-elastic groove.
The specific embodiment
are further described the utility model below in conjunction with accompanying drawing and embodiment, but not as the foundation to the utility model restriction.
embodiment.A kind of general inner hexagon spanner lengthening cover, as shown in Figure 1, comprise extension bar 1, extension bar 1 bottom is provided with and inner hexagon spanner 6 corresponding connecting holes, and the cylindrical of extension bar 1 bottom is provided with screw thread 8, and screw thread 8 is provided with locking nut 5; Extension bar 1 top is provided with rectangular opening 2 and handle hole 4, is provided with handle 3 in the handle hole 4.Screw thread 8 places on the cylindrical of extension bar 1 bottom are provided with elastic groove 9.Locking nut 5 epimeres are cylindric, and the hypomere of locking nut 5 is awl tubular 7, and interior circle cylindraceous is provided with and screw thread 8 corresponding internal threads.
The method for using of
the utility model: when using general inner hexagon spanner lengthening of the present invention to overlap; The connecting hole of extension bar bottom is enclosed within inner hexagon spanner 6 tops; Then locking nut 5 is tightened; Because locking nut 5 hypomeres are conically shaped, the endoporus of taper compresses inner hexagon spanner 6 tops.It is tight more that locking nut 5 is twisted; The connecting hole of extension bar bottom is because the effect meeting of elastic groove 9 is received littler and littler; So the extension bar of the utility model not only can be used for the inner hexagon spanner of standard specification; Also can be used for less than standard specification certain limit inner hexagon spanner, accomplish that one takes into account the inner hexagon spanner of several kinds of specifications to extension bar simultaneously.
can be screwed the inner hexagon spanner of the screw of φ 6～φ 12 diameter ranges simultaneously like can the extend lengthening cover of the inner hexagon spanner of screwing φ 12 diameter screws of maximum.
