Abstract

The invention discloses a multifunctional disassembling jig which comprises a handle and a head portion located at one end of the handle. The head portion comprises a barrel sleeve and rigid pin posts densely distributed in the barrel sleeve, and the axis of each rigid pin post is parallel to the axis of the barrel sleeve. The rigid pin posts can elastically contract inside the barrel sleeve in the axis direction of the barrel sleeve through elastic elements, and the length of each rigid pin post is not larger than the length of the barrel sleeve. The head portion of the disassembling jig can be suitable for various fasteners with more size ranges where the maximum diameter is not larger than the diameter of the barrel sleeve; in actual application, various types of disassembling jigs can be replaced by the multifunctional disassembling jig, so that the situation that jigs are lost since too many jigs are carried is avoided.

Description

Multi-functional disassembling jig

Technical field

The present invention relates to a kind of multi-functional disassembling jig.

Background technology

Bolt, screw, nut, stud, steel-wire screw-socket etc. are that a class application is fastenedly connected with machine components very widely, on various machinery, equipment, vehicle, boats and ships, railway, bridge, building, structure, instrument, instrument, instrument and articles for use etc., securing member miscellaneous can be seen.Its feature is that description is various, and performance purposes is different, and standardization, seriation, unitized kind of degree are also high.Conventional spanner in prior art, as fork spanner, monkey wrench etc., carry out fastening or this kind of part of loose unloading, but traditional tightening tool often can not meet actual production requirement, as: fork spanner, usual one the securing member of applicable for fork spanner two kinds of sizes at the most, function singleness, usually need multiple fork spanners of plurality of specifications with the use of, number of tools is many, is easy to cause the loss of instrument or be scattered during use.And although the size range that monkey wrench uses is slightly wide, regulate underaction owing to pulling lip, and adjustable range is limited, still needs frequently to change different instrument when running into the more device of fastener sizes kind, the application in production reality can not be met.

Summary of the invention

The technical problem to be solved in the present invention is to provide a kind of multi-functional disassembling jig.

For solving the problems of the technologies described above, the technical solution used in the present invention is:

A kind of multi-functional disassembling jig, comprise handle and the head being positioned at described handle one end, described head comprises jacket casing and is clouded in the rigid needle post of described jacket casing inside, the axis of described rigid needle post and the axis being parallel of described jacket casing, described rigid needle post can by flexible member axis direction elastic shrinkage along described jacket casing in described jacket casing, and described rigid needle column length is no more than described jacket casing length.

This flexible member is the flexible members such as spring, and this rigid needle post can elastic telescopic at axial direction, but not swingable in circumferential direction.

Preferably, described handle comprises arm and is positioned at the handle of described arm end, and described handle is rotatably coupling in described arm by rotating shaft.

Preferably, described arm is provided with annular stop portion near one end of described rotating shaft.

Preferably, described arm has handle accommodating cavity.

Preferably, described jacket casing is the Hexagonal jacket of inner wall coarse.

Preferably, the outer peripheral face of described rigid needle post is matsurface.

The beneficial effect that the present invention reaches:

The head of disassembling jig of the present invention is applicable to maximum gauge and is no more than the more polymorphic type of jacket casing diameter, the securing member of more size ranges, can replace polytype disassembling jig in actual applications, avoids the loss causing instrument because carrying too much;

In use, when the size of securing member as nut is less than sleeve dimensions, the rigid needle post within this nut edge is compressed, and the rigid needle post being close to its edge can not be compressed, play fixing position-limiting action to nut, now turning handle just can by fastening nuts or loose unloading again.

Fig. 2 is the left view of disassembling jig head in Fig. 1;

Fig. 3 is the schematic diagram of head when dismantling pentagon nut in Fig. 2;

Wherein: 1. handle, 11. arms, 12. handles, 13. handle accommodating cavity, 2. heads, 21. jacket casings, 22. rigid needle post, 3. rotating shafts, 4. annular stop portion.

Detailed description of the invention

Below in conjunction with accompanying drawing, the invention will be further described.Following examples only for technical scheme of the present invention is clearly described, and can not limit the scope of the invention with this.

As Figure 1-3, a kind of multi-functional disassembling jig, comprise handle 1 and the head 2 being positioned at handle 1 one end, this head 2 comprises jacket casing 21 and is clouded in the rigid needle post 22 of jacket casing 21 inside, the axis of rigid needle post 22 and the axis being parallel of jacket casing 21, rigid needle post 22 can by flexible member axis direction elastic shrinkage along jacket casing 21 in jacket casing 21, and rigid needle post 22 length is no more than jacket casing 21 length.

Particularly, above jacket casing 21 is the Hexagonal jacket of inner wall coarse, and the outer peripheral face of rigid needle post 22 is matsurface.

This flexible member is the flexible members such as spring, and this rigid needle post 22 can elastic telescopic at axial direction, but not swingable in circumferential direction.

In use, when the size of securing member as nut is less than sleeve dimensions, rigid needle post within this nut edge is compressed (as the region that Fig. 3 evil mind circle represents), the rigid needle post being close to its edge can not be compressed, play fixing position-limiting action to nut, now turning handle just can by fastening nuts or loose unloading again.

Preferably, handle 1 comprises arm 11 and is positioned at the handle 12 of arm 11 end, and handle 12 is rotatably coupling in arm 11 by rotating shaft 3.Arm 11 is provided with annular stop portion 4 near one end of rotating shaft 3.Arm 11 has handle accommodating cavity 13.

Handle accommodating cavity 13 is for holding handle 12, and handle 12 is as the extension of power-assisted arm 11, and can take out in handle accommodating cavity 13 as required, the storage of instrument is convenient in this design, saves space.

The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the technology of the present invention principle; can also make some improvement and distortion, these improve and distortion also should be considered as protection scope of the present invention.
