Abstract
The utility model discloses a dismounting tool, comprising a sleeve barrel, a pry bar and a pry-bar sleeve frame installed on the sleeve barrel, wherein, one end of the pry-bar sleeve frame is fixed on the sleeve barrel with a connecting piece, and the other end penetrates the pry bar in insertion. In such a way, the utility model has the advantages that the selection of the thickness of the pry bar is free from the limitation of the outer diameter of the sleeve barrel; when overexertion is needed to dismount fastening elements, such as nuts, etc., the pry bar is not easy to bend and deform; the dismounting of the utility model has the advantages of convenience and labor saving.
Description
The utility model relates to hardware ﹠ tools manufacturing technology field, relates in particular to a kind of extracting tool.
Before the utility model was made, some machineries were older in bad repair, and its securing member such as nut, Bolt dismantling must be used very big strength.After and for example the nut bolt of doughnut was tightened with the aerofoil machine, dismounting was very painstaking in the open air.Be inserted in the sleeve with common employing crowbar, sleeve is then overlapping the securing member of required dismounting, utilize the way of lever principle dismounting, though economized a little power, because the external diameter of crowbar is subjected to the restriction of sleeve outer diameter, when running into above-mentioned situation, since can not select the crowbar of external diameter overstriking for use, when playing sled, the former and supporting crowbar of sleeve, flexural deformation easily, even can not firmly dismantle.
The purpose of this utility model is to provide a kind of sleeve outer diameter that is not subjected to limit, greatly overstriking crowbar external diameter extracting tool.
The technical solution of the utility model is that a kind of extracting tool comprises sleeve, crowbar, is characterized in, is installed in the crowbar stock on the sleeve in addition; Described crowbar stock one end is fixed on the sleeve with connector, and the other end interts crowbar.
Described crowbar stock is two, and its shape and size are identical; Described connector is a screw bolt and nut.
The utility model has the advantages that owing to adopt the crowbar stock, the crowbar external diameter is not subjected to the restriction of sleeve outer diameter; When using bigger power dismounting securing member, can choose the crowbar of external diameter overstriking, thereby more convenient, laborsaving dismounting can not make again crowbar because of overexertion flexural deformation.
Accompanying drawing 1 is a structural representation of the present utility model.
Below in conjunction with drawings and Examples, the utility model is further described.
As shown in Figure 1, the inventor adopts small one and large one two hex nuts to be welded into crowbar stock 1, the internal orifice dimension turning of the end that crowbar stock 1 is little is to the same with the size in hole of interting crowbar on the sleeve 3, and the big end internal orifice dimension of crowbar stock 1 then turning is big 1～2 millimeter to the external diameter than the crowbar 4 of overstriking.Select for use with onesize two hex nuts of crowbar stock 1 and be welded into crowbar stock 2; The hole internal diameter at same turning crowbar stock 2 two ends is identical with crowbar stock 1.Select stud 5 and nut 6,7 for use, with crowbar stock 1 and crowbar stock 2 and tightly on sleeve 3.
During use, sleeve 3 is enclosed within on the nut that is disassembled, the crowbar 4 of overstriking is injected in the hole of big end of crowbar stocks 1 and crowbar stock 2, still adopt lever principle, can make things convenient for, effortlessly dismounting.
