Description
Technical field
the utility model relates to box spanner technical field, is a kind of nigger spanner.
Background technology
at present in daily production, service work, some bolt is inside channel-section steel, angle bar or equipment recess, the hand-tight solid difficulty of common plate, waste time and energy, bolt tightness is poor, and common double off-set spanners, leatherhead wrench cannot extend into the fastening point of recess, and impact wrench length does not reach again, time has been grown and has easily caused generation hidden danger, threatens safety in production.
Summary of the invention
the utility model provides a kind of nigger spanner, overcomes the deficiency of above-mentioned prior art, and it effectively can solve the not easily fastening and security hidden trouble caused of recess bolt.
the technical solution of the utility model is realized by following measures: a kind of nigger spanner, comprise sleeve, hand lever, extension bar, nut, sleeve is provided with 12 jiaos of opening up blind holes along axis, lower cartridge and hand lever top are fixed together, coaxially be fixed with extension bar bottom hand lever, bottom extension bar, be fixed with nut.
here is the further optimization and/or improvements to above-mentioned utility model technical scheme:
above-mentioned hand lever external wall of upper portion can be fixed with Anti-slip cover, and Anti-slip cover top is provided with the anti-slip veins of longitudinal separation distribution.
above-mentioned hand lever and extension bar can be fixed together by welding.
above-mentioned extension bar external diameter is less than hand lever external diameter.
the utility model reasonable and compact in structure, easy to use, it can stretch into recess by extension bar and reach more than 10 centimetres, is used and can be finished the work fast, efficiently, eliminate safe hidden trouble by scene.
Accompanying drawing explanation
accompanying drawing 1 is that the master of the utility model most preferred embodiment looks half section structural representation.
coding in accompanying drawing is respectively: 1 is sleeve, and 2 is hand lever, and 3 is extension bar, and 4 is nut, and 5 is Anti-slip cover.
Detailed description of the invention
the utility model by the restriction of following embodiment, can not determine concrete embodiment according to the technical solution of the utility model and actual conditions.
in the utility model, for convenience of description, the description of the relative position relation of each parts is all be described according to the Butut mode of Figure of description 1, as: the position relationship of upper and lower, left and right etc. determines according to the Butut direction of Figure of description.
below in conjunction with embodiment and accompanying drawing, the utility model is further described:
as shown in Figure 1, this nigger spanner comprises sleeve 1, hand lever 2, extension bar 3, nut 4, and sleeve 1 is provided with 12 jiaos of opening up blind holes along axis, and sleeve 1 bottom and hand lever 2 top are fixed together, coaxially be fixed with extension bar 3 bottom hand lever 2, bottom extension bar 3, be fixed with nut 4.During use, sleeve 1 is goed deep into recess and to be locked bolt, make nut 4 be placed in handled easily place by extension bar 3, with tool holding nuts 4 such as spanners, drive extension bar 3, hand lever 2 and sleeve 1 to rotate, can finish the work fast, efficiently, eliminate safe hidden trouble.Add man-hour, sleeve 1 and the machine-shaping of hand lever 2 one.
according to actual needs, above-mentioned nigger 1 spanner can be made further optimization and/or improvements:
as shown in Figure 1, hand lever 2 external wall of upper portion is fixed with Anti-slip cover 5, Anti-slip cover 5 top is provided with the anti-slip veins of longitudinal separation distribution.
as shown in Figure 1, hand lever 2 and extension bar 3 are fixed together by welding.Extension bar 3 intensity can be increased like this.
as shown in Figure 1, in order to adapt to different operating environment, extension bar 3 external diameter is less than hand lever 2 external diameter.
above technical characteristic constitutes most preferred embodiment of the present utility model, and it has stronger adaptability and best implementation result, can increase and decrease non-essential technical characteristic according to actual needs, meet the demand of different situations.
