Description
Technical field
The utility model relates to ratchet spanner technical field, specifically refers to a kind of ratchet spanner of energy extending length.
Background technology
The handle of common ratchet spanner is generally regular length in the market, cannot regulate the length of ratchet spanner as required, when needing larger torsion, just needs the ratchet spanner selecting handle longer, and such ratchet spanner carries very inconvenience.In order to solve the problem, Authorization Notice No. is Chinese utility model patent " a kind of adjustable ratchet wrench " (application number: 200620021666.6) disclose a kind of structure of CN200970742Y, it comprises spanner, fixed handle and flexible handle, spanner is connected with fixed handle, chute is had in fixed handle, the flexible handle that can slide in fixed handle chute is flexibly connected with fixed handle, fixed handle and flexible handle are fixed by snap ring and bolt, during use, as required flexible handle is pulled out applicable length from the chute of fixed handle, with two snap rings and bolt, the afterbody of fixed handle and flexible handle are fixed together, finish using and flexible handle can be pushed in chute.The ratchet spanner of said structure achieves length adjustment, to a certain extent for user provides convenience.But because flexible handle is hidden in fixed handle by it, cause the volume of fixed handle comparatively large, and the overall weight of ratchet spanner is comparatively large, user can feel to compare effort after a long time use, for user brings certain inconvenience; In addition, the ratchet spanner manufacturing cost of said structure is also higher.
Therefore, for current ratchet spanner, await doing further improvement.
Utility model content
Technical problem to be solved in the utility model is the present situation for prior art, provides a kind of and can regulate length and ratchet spanner easy to use.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind of ratchet spanner, comprise handle and be arranged at the spanner of this handle front end, it is characterized in that: also comprise head rod and the second connecting rod, the rear end of described head rod is connected with the front end of handle, the front end of described head rod caves inward formation first connector, the rear end of described spanner has second connector suitable with the first connector, the rear end of described second connecting rod has the joint among three members suitable with the first connector, the front end of described second connecting rod caves inward and is formed with four connector suitable with the second connector.
In such scheme, the front end of described handle caves inward and is formed with a mounting groove, the rear end of described head rod is shaped to the joint pin that can insert in mounting groove, under described head rod and handle assemble completion status, the first connector of described head rod is exposed to outside the port of mounting groove.Adopt said structure, so that the production of ratchet spanner and assembling.
As preferably, described first connector and the 4th connector are shaped to four measure-alike square holes, and described second connector and joint among three members are shaped to the square head matched with above-mentioned four square holes, and this square head is equiped with spring steel ball.During use, be plugged in the first connector of head rod by the second connector of spanner, the ratchet spanner of ratchet spanner as routine can be used, ratchet spanner length is now extended; If first the joint among three members of the second connecting rod rear end is plugged in the first connector of head rod, then the second connector of spanner is plugged in the 4th connector of the second connecting rod front end, ratchet spanner length can be made to be extended, to be applicable to larger torsion.
As improvement, the second described connecting rod is one or more, end to endly when described second connecting rod is many be connected between spanner and head rod, adopt this structure that ratchet spanner can be selected as required to need the length extended, second connecting rod can be disassembled when not using and carry, more for convenience.
Preferably, there is between the front end of described spanner and the second connector a kink seamlessly transitted, facilitate the use lever principle and reach good biasing effect.
Compared with prior art, because the utility model is provided with the second connecting rod removably connected between handle and spanner, when user needs larger torsion, can the second connecting rod inserting-assembling type be connected between spanner and handle, thus extend the length of ratchet spanner entirety, to reach labour-saving effect; During without the need to extending the length of ratchet spanner, spanner can be directly connected in the front end of handle, the weight increasing ratchet spanner because of the existence of the second connecting rod can be avoided like this, easy to use; Meanwhile, the detachable connection structure on ratchet spanner between each parts also brings great convenience for assembling and carrying.

Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the utility model is described in further detail.
As shown in figs. 1 to 6, the ratchet spanner of the present embodiment comprises handle 1, head rod 2, second connecting rod 3 and be arranged at the spanner 4 of handle 1 front end, the rear end of head rod 2 is connected with the front end of handle 1, the front end of head rod 2 caves inward formation first connector 22, concrete, the front end of handle 1 caves inward and is formed with a mounting groove, the rear end of head rod 2 is shaped to the joint pin 21 that can insert in mounting groove, under head rod 2 and handle 1 assemble completion status, first connector 22 of head rod 2 is exposed to outside the port of mounting groove, so that the production of ratchet spanner and assembling.The rear end of spanner 4 has second connector 41 suitable with the first connector 22, the front end that the rear end of the second connecting rod 3 has joint among three members 31, the second connecting rod 3 suitable with the first connector 22 caves inward and is formed with four connector 32 suitable with the second connector 41.During use, as shown in Figure 2, be plugged in the first connector 22 of head rod 2 by the second connector 41 of spanner 4, the ratchet spanner of ratchet spanner as routine can be used, ratchet spanner length is now extended; As shown in Figure 1, first the joint among three members 31 of the second connecting rod 3 rear end is plugged in the first connector 22 of head rod 2, then the second connector 41 of spanner 4 is plugged in the 4th connector 32 of the second connecting rod 3 front end, ratchet spanner length can be made to be extended, to be applicable to larger torsion.If need larger for the length of ratchet spanner prolongation, the second connecting rod 3 in the present embodiment can have many, be connected between spanner 4 and head rod 2 after many second connecting rod 3 first places connect, to reach the length needing to extend, second connecting rod 3 can be disassembled when not using and carry, more for convenience.
In the present embodiment, first connector 22 and the 4th connector 32 are shaped to four measure-alike square holes, second connector 41 and joint among three members 31 are shaped to the square head matched with above-mentioned four square holes, and this square head is equiped with spring steel ball 100, be exactly at square head surface borehole, built-in little spring, then inlay steel ball formation.Between the front end of spanner 4 and the second connector 41, there is a kink seamlessly transitted 40, facilitate the use lever principle and reach good biasing effect.
