Abstract
The utility model relates to a metal tool, which is an adjustable sleeve-cylinder spanner. The lower part of the sleeve cylinder of the spanner forms an inner hexagonal shape; one side of the middle part of the sleeve cylinder has a boss; a gap is arranged between the boss and the other side of the sleeve cylinder; the interior of the gap is provided with a plurality of inserting pieces. The inserting pieces are lifted for making the working surface in the sleeve cylinder enlarged or reduced. Thus, the utility model can be applicable to screw bolts (nuts) with different specifications. The functions of the choice, the lifting, and the locking of the inserting pieces can be completed by a positioning key, a size ring, and a size key together on the sleeve cylinder. The lower parts of the inserting pieces are provided with oblong single-face bodies, and can also be bent into two-face bodies or three-face bodies, which are intersected at a certain angle in order to increase the contact with the screw bolts (the nuts).
Description
The utility model relates to a kind of hardware ﹠ tools, and it is a kind of adjustable spanner.
People are in activity in production and daily life now, and often the spanner that uses has box spanner, double offset ring spanner, monkey wrench etc.Yet above-mentioned spanner but respectively has its pluses and minuses.Though monkey wrench can be regulated easily, yet its spanner space required in using is bigger.Box spanner needs often to change collet head, and adapting to the nut of different size, and collet head is very easy to lose.The every handle of double offset ring spanner has only the pullover of two kinds of sizes, and use face is narrow.
The purpose of this utility model is to provide a kind of instrument that overcomes above-mentioned various spanner shortcomings, and it can regulate in classification, and required spanner space is little, carries, uses easily.
The technical solution of the utility model is such:
Respectively there is a sleeve at two of spanner, arranges in opposite directions.The contacted working face of lower cartridge and bolt (mother) is hexagonal.One side of sleeve middle part has a boss, with it inserted sheet is located.Sleeve inner is provided with several inserted sheets, and inserted sheet has three grooves above for certain thickness rectangle is arranged.Inserted sheet is arranged between boss and the sleeve opposite side, and the quantity of inserted sheet can freely be set.Mention inserted sheet, the working face in the sleeve just can enlarge.So just, the bolt of applicable different size (mother).The function of lifting inserted sheet is by positioning key, size ring, dimension key, finish jointly.
Positioning key is the part torus that an inside ligulate projection is arranged, and positioning key injects the inside of sleeve, and its ligulate projection embeds in the nethermost groove of inserted sheet, thereby has guaranteed that inserted sheet can be from landing in the sleeve.Locating ring can not upper and lowerly move, but can rotate with the size ring.
The size ring is positioned at the positioning key outside, is a cylindrical body, is fixed with dimension key above.Dimension key embeds in the middle groove of inserted sheet.Rotate the size ring, selected required inserted sheet of mentioning is pulled upwardly then, is rotated counterclockwise the size ring again, and the part of dimension key just can embed in the holddown groove of protective sleeve, and this moment, inserted sheet just locked by the desired position.
The top of sleeve is a cylindrical body, and removing on it has and inserted sheet, outside the groove that positioning key, dimension key adapt, also has a holddown groove, is used for the locking of inserted sheet.
The bottom of inserted sheet also can be made into, and the two sides body or the trihedral of Xiang Jiaoing makes it to abut against on interior hexagonal two or three faces of sleeve at a certain angle, increases the contact-making surface with bolt (mother).
Characteristics of the present utility model are: add several inserted sheets in the sleeve of interior hexangle type, the lifting inserted sheet just can enlarge or reduce the size of sleeve inner working face, with the bolt (mother) that adapts to different size.
Below in conjunction with accompanying drawing in detail, embodiment of the present utility model is described in detail.
The profile of accompanying drawing 1 adjustable socket wrench.
Accompanying drawing 2 sleeve lateral sectional view.
The transverse cross-sectional view of accompanying drawing 3 locating rings.
The transverse cross-sectional view of accompanying drawing 4 size rings.
Among the figure: 1. sleeve 2. positioning keys 3. size rings 4. dimension key 5.B inserted sheet 6.A inserted sheets 7. holddown grooves
As shown: at first boss is processed at the middle part of sleeve, and A inserted sheet (6) is set in the inboard of sleeve (1), B inserted sheet (5), the top of inserted sheet has three keyways.The top of sleeve (1) is equipped with positioning key (2), the ligulate projection that it is inside embeds in the nethermost groove of inserted sheet, then, puts size ring (3) in the outside of sleeve and positioning key (2), dimension key (4) is embedded in the medial launder of inserted sheet, and fixing with size ring (3).The top of sleeve (1) has holddown groove (7).
The course of work of adjustable socket wrench is such, rotate size ring (3), choose the inserted sheet that need be raised, upwards spur size ring (3) then, by dimension key (4) required inserted sheet of mentioning is mentioned, rotate counterclockwise the size ring then, make dimension key (4) embed holddown groove (7), all like this inserted sheets are just locked, and spanner can use.
Claims (2)
1. adjustable socket wrench, it is characterized in that: the bottom of sleeve (1) is interior hexagon, its middle part one side has a boss, between the opposite side of boss and sleeve (1) certain slit is arranged, be provided with inserted sheet therebetween, inserted sheet is for there being certain thickness cuboid, the number of inserted sheet can arbitrarily be set, top one side of inserted sheet has three grooves, and positioning key (2) is for there being the part torus of an inside ligulate projection, and the ligulate projection of positioning key (2) embeds in the nethermost groove of inserted sheet, inserted sheet is played positioning action, size ring (3) is enclosed within the outside of positioning key (2), and fan-shaped dimension key (4) is fixed into one with size ring (3), and embeds in the middle groove of inserted sheet.
2. adjustable socket wrench as claimed in claim 1 is characterized in that described inserted sheet bottom is bent into crossing at a certain angle two sides body or trihedral etc.
