Description

The telescopic spanner of a kind of handle
Technical field
The utility model relates to the instruments of labour field, particularly be that a kind of handle part length can be regulated flexible spanner.
Background technology
Spanner is one of a kind of hand tools commonly used, is mainly formed by structural carbon steel or structural alloy steel manufacturing.In use, often utilize lever principle to twist opening or trepanning firmware that bolt, screw, nut and other screw threads are tightly held bolt or nut.Spanner is made up of handle and the working end that is arranged on handle one or both ends places usually, because spanner can be used as the laborsaving lever of a kind of power arm greater than resistance arm, its rotating fulcrum is arranged near the working end, the foreign object that will twist by the working end clamping for these need, position after handle comparatively leans on then applies one group of less external force along the screw thread rotation direction, so just, can realize using less power to twist bolt or nut is held the function of the opening or the trepanning of bolt or nut, thus the operating efficiency when having improved people's handwork greatly.
At present, spanner commonly used mainly comprises following several types in life: 1, fork spanner; 2, double offset ring spanner; 3, combination wrenches; 4, adjustable wrench; 5, hook spanner; 6, box spanner; 7, inner hexagon spanner; 8, torque spanner.Though present employed spanner is of a great variety, can well satisfy the needs of user in the different operating field.But, there is a problem to be, in use often run into the pinch bar position that is used to serve as power arm and fall short of, to such an extent as to be the more weak users of some wrist power, bring the embarrassment that can't pull use.Though some spanner has carried out the lengthening of hommization on the length of handle, can cause so again and in small space, use inconvenience and the trouble that is not easy to carry.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of handle telescopic spanner at the deficiencies in the prior art, to solve the existing existing many weak points of spanner.
To achieve these goals, the utility model is to realize by the following technical solutions:
The telescopic spanner of a kind of handle, the single-end spanner that comprises one group of traditional structure, the spanner of described band Telescopic handle comprises that also one is convenient to the flexible outer casing that uses of described single-end spanner, and described outer casing one end is provided with one group of mounting groove that matches with described single-end spanner handle; Described single-end spanner bottom is provided with one group of fixture, and what the telescopic handle of described single-end spanner slided is assemblied in the described mounting groove, and by described fixture positioning and fixing on described outer casing.
Described outer casing is one group of handle shape housing of being made by the stainless steel metal material.
Described fixture is made up of one group of bolt and butterfly nut.
The utility model is simple in structure, easy to use, is nested in the traditional singlehanded spanner in the outer casing, is free to carry out the telescopic adjustment of handle part length, satisfies the needs of user under the different operating environment; And outer casing is made by the stainless steel metal material, thereby has increased durability of the present utility model greatly; And the fixture of being made up of bolt and butterfly nut, because it can have been made things convenient for use of the present utility model greatly by the characteristic of user's manual adjustments.
Description of drawings
Describe the utility model in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is a vertical view of the present utility model.
Fig. 2 is a front view of the present utility model.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with the specific embodiment, further set forth the utility model.
The utility model is the telescopic spanner of a kind of handle, be mainly used in and solve existing spanner, because the length at pinch bar position often is designed to the length that is easy to carry and uses, to such an extent as in use, can run into the handle that serves as power arm and fall short of, and have influence on the problem that the user uses.
With reference to figure 1,2, be the telescopic spanner of a kind of handle related in the utility model, the single-end spanner 100 that mainly comprises one group of traditional structure, and also need design a outer casing 200 that these single-end spanner 100 handle parts 120 freely stretch and use of being convenient on the basis of this single-end spanner 100, this outer casing 200 can be designed to a handle shape housing of being made by the stainless steel metal material, is provided with one group of mounting groove 210 that matches with described single-end spanner 100 handle parts 120 at the one end; And the bottom at this single-end spanner 100 also need be equipped with one group of fixture 300.
The convenience when considering the utility model use and the cost performance of entire product, fixture 300 can be designed to the fixture of bolt mounting structure, just is made up of one group of plain bolt 310 and one group of butterfly nut 320 such as fixture 300 in the present embodiment.
For this reason, the utility model when mounted, the handle part 120 of single-end spanner 100 can be along being assemblied in the outer casing 200 of mounting groove 210 scalable slips, and carry out snaps into position by plain bolt 310 and butterfly nut 320.
The utility model in use, because plain bolt 310 plays with butterfly nut 320 handle part 120 is carried out the effect of snaps into position, before use, the user only need unscrew the butterfly nut 320 that is held on the plain bolt 310 earlier, thereby just can be along mounting groove 210, stretch out by the slip of handle part 120 in mounting groove 210, expose adjusting in handle part 120 length of outer casing 200 outsides.When the length of user according to the required drive arm, thereby when handle part 120 is adjusted to suitable position, just can tighten butterfly nut 320, make handle part 120 continue quilt this position of snaps into position firmly, the user just can be as using common wrench then, be buckled on the nut or bolt that needs to rotate by working end 110, position after outer casing 200 comparatively leans on applies one group of less external force along the screw thread rotation direction, just can reach the purpose of nut or bolt Fast Installation and dismounting.After end is installed, the user just can be on the basis of unscrewing butterfly nut 320, handle part 120 is slid into the bottom position of mounting groove 210, thereby this handle part 120 is contracted in the outer casing 200 fully, need tighten butterfly nut 320 for last, thereby make handle part 120 snaps into position in this position, just can satisfy portable purpose.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
