Abstract
The utility model provides a spanner with a master and a subordinate sockets, which is composed of a socket handle and a master and a subordinate sockets, wherein, the inner diameters of socket holes which are arranged at both ends of the master socket have different specifications. The specifications of the outside diameter of at least one end of the subordinate box fit to the specifications of the inner diameters of the master socket. The subordinate socket can be also placed in the master box. The specifications of the inner diameters of socket holes at both ends of the subordinate box can be the same or different. A transverse through hole which is arranged in the middle of the master box is provided with a notch. A salient point is arranged on the socket handle, and the size of the salient point fits to the size of the notch. The utility model is suitable for the operation of nuts or screw bolts with a plurality of specifications. The utility model has the characteristics of simple fabrication, low cost, easy assembly, convenient use, portability, etc. The spanner with a master and a subordinate sockets, which is an ideal hand tool, can be widely used in mechanical maintenance industry.
Description
The utility model relates to a primary and secondary box spanner, belongs to field of hand.
Existing box spanner generally is only applicable to two kinds of specifications of nuts or bolt are operated, if the nut or the bolt of plurality of specifications are operated, needs to be equipped with many box spanners, has increased volume and weight, is not easy to carry and use.The box spanner report that replaceable sub-sleeve is also arranged in Chinese patent, but because of making complexity, the cost height, inconvenience is used, and is difficult to promote.
The purpose of this utility model be to avoid above-mentioned weak point of the prior art and provide a kind of make simple, cost is low, the primary and secondary box spanner of being convenient to change the different size sub-sleeve.
The purpose of this utility model can reach by following measure: the primary and secondary box spanner is made up of sleeve handle, mother sleeve, sub-sleeve, it is characterized in that: the mother sleeve two ends have the different hexagon trepanning of internal diameter specification respectively, its stage casing has horizontal through hole, on this horizontal through hole a breach is arranged.One salient point is arranged on above-mentioned sleeve handle, and its size is slightly less than above-mentioned breach, and can insert in the above-mentioned horizontal through hole.At least one end of sub-sleeve has the hexagon column that external diameter is slightly less than mother sleeve hole internal diameter, and sub-sleeve can be placed in the trepanning of mother sleeve.
The hexagon trepanning internal diameter at above-mentioned sub-sleeve two ends can be made into identical or different specification.
The utility model can be designed to serial size owing to sub-sleeve trepanning internal diameter, thereby can be used for the operation of multiple different size nut or bolt, both can be used for common nut or bolt, also can utilize hexagonal nut or bolt in the dismounting of sub-sleeve profile.This production is simple, and is with low cost, and assembling is easy to carry easily, is a kind of desirable hand tools.
Description of drawings:
Accompanying drawing 1 is the stereogram of primary and secondary box spanner.
Accompanying drawing 2 is a sleeve handle.
Accompanying drawing 3 is the sub-sleeve stereogram.
Accompanying drawing 4 has the sub-sleeve cutaway view of different inner diameters for the two ends trepanning.
Accompanying drawing 5 has the sub-sleeve stereogram of different size external diameter for two ends.
The horizontal through hole of (1) sleeve handle (2) mother sleeve (3) sub-sleeve (4) (5) salient point wherein
Be described in further detail below in conjunction with accompanying drawing:
Adopt Domestic Seamless, according to bolt or nut specification, make the mother sleeve (2) of the hexagon trepanning that there is different inner diameters at two ends, symmetry is drilled with horizontal through hole (4) with a small gap respectively in this mother sleeve stage casing, and joins the steel sleeve handle (1) that there is a salient point (5) at a middle part.During use, handle (1) is inserted horizontal through hole (4), salient point (5) snaps in mother sleeve (2) along breach, rotation slightly, and handle is fixed on the mother sleeve like this, so that be difficult for landing in use.Sub-sleeve (3) has an end to have to be slightly less than the hexagon column of the interior trepanning of mother sleeve (2) at least, so that insert in the interior trepanning of mother sleeve (2), and two ends have trepanning in the hexagon of different inner diameters.According to actual needs, the difference end of the sub-sleeve (as accompanying drawing 4) of the hexagon trepanning internal diameter of above-mentioned different inner diameters is inserted in the mother sleeve trepanning, can be assembled into nut or the bolt of box spanner to be used for different size of different size trepanning internal diameter.For being used for bigger nut of external diameter or bolt, an end of sub-sleeve also can be made into mother sleeve head (as accompanying drawing 5), and to increase sleeve intensity, unlikely pulling because of overexerting split.
Claims (3)
1, a kind of primary and secondary box spanner comprises sleeve handle (1), mother sleeve (2), sub-sleeve (3).It is characterized in that: mother sleeve (2) two ends have trepanning in the hexagon respectively; Its stage casing has horizontal through hole (4), handle (1) inserts in the horizontal through hole (4), sub-sleeve (3) has an end to have to be slightly less than the hexagon column of the interior trepanning of mother sleeve (2) at least so that insert in the hexagon of mother sleeve (2) in the trepanning, and have hexagonal in trepanning.
2, primary and secondary box spanner according to claim 1 is characterized in that: the internal diameter of sub-sleeve (3) two ends hexagon trepanning can be made into identical or different specification.
3, primary and secondary box spanner according to claim 1 and 2 is characterized in that: on the above-mentioned horizontal through hole breach is arranged, a salient point (5) is arranged on the above-mentioned sleeve handle (1), its size is slightly less than above-mentioned breach.
