Description
Technical field
The utility model relates to a kind of tool fitting technical field, relates in particular to a kind of extension type spanner.
Background technology
In electric power installation, as worked in power distribution cabinet or in batch meter, be subject to the restriction of equipment in casing, spatial joint clearance is narrower and small, common wrench is difficult for being rotated or rotates not in place, need to repeatedly adjust the anglec of rotation, operating personnel's hand stretches inconvenience or easily injured in casing, and the thickness of all kinds casing is also different, staff is at case manipulation in vitro, common sleeve length is also inadaptable, sometimes even cannot operate, thereby affect operating personnel's operating efficiency.
Utility model content
Technical problem to be solved in the utility model is to provide extension type spanner a kind of simple in structure, easy to use.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of extension type spanner, comprise spanner portion, connecting portion and power part, it is characterized in that described connecting portion is comprised of connecting rod, sleeve and the first pin, described power part is comprised of power arm, power arm sleeve and the second pin, described spanner portion is fixedly connected with described connecting portion, and described connecting portion becomes 90 degree angles to be fixedly connected with described power part.
Preferably, described connecting rod is provided with at least two the first adjustment holes, described the first adjustment hole at described pitman shaft to becoming yi word pattern evenly distributed and radially run through, described sleeve top is provided with the first fixing hole radially running through, and described the first pin can be connected arbitrarily with described the first adjustment hole by described the first fixing hole.
Preferably, described power arm is provided with at least two the second adjustment holes, described the second adjustment hole axially becomes yi word pattern evenly distributed and radially run through at described power arm, described power arm sleeve top is provided with the second fixing hole radially running through, and described and pin can be connected arbitrarily with described the second adjustment hole by described the second fixing hole.
The beneficial effect that adopts technique scheme to produce is: the utility model improves on the basis of conventional wrench.The one, the connecting portion of wrench can stretch, and flexible amplitude is 0cm to 10cm, gear of every 2cm; The 2nd, the power part of wrench also can stretch, and flexible amplitude is 0 cm to 20 cm, gear of every 5cm.Connecting portion and power part are 90 degree angles, like this screw dismounting rotation is carried out outward by changing in casing at casing, according to the thickness of casing, can adjust the length of connecting portion, according to the size of revolving force, length that can motivation of adjustment portion, due to accessible in rotation, can rotate to arbitrarily angled, do not need wrench repeatedly to adjust, solved crawl space and operated inconvenient problem.The utility model is simple in structure, is easy to preparation, by the connecting portion of spanner and power part are designed to telescopic right-angle structure, makes spanner can adapt to different spaces, and the requirement of different length has improved the utilization rate of spanner greatly, has improved operating efficiency.

The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, a kind of extension type spanner, comprises spanner portion 1, connecting portion 2 and power part 3, and described spanner portion 1 is fixedly connected with described connecting portion 2, and 3 one-tenth 90 degree angles of described connecting portion 2 and described power part are fixedly connected with.
As shown in Figure 2, described connecting rod 2-1 is provided with at least two the first adjustment holes, described the first adjustment hole at described pitman shaft to becoming yi word pattern evenly distributed and radially run through, described sleeve 2-2 top is provided with the first fixing hole radially running through, and described the first pin 2-3 can be connected arbitrarily with described the first adjustment hole by described the first fixing hole.
As shown in Figure 3, described power arm 3-1 is provided with at least two the second adjustment holes, described the second adjustment hole axially becomes yi word pattern evenly distributed and radially run through at described power arm, described power arm sleeve 3-2 top is provided with the second fixing hole radially running through, and described and pin 3-3 can be connected arbitrarily with described the second adjustment hole by described the second fixing hole.
The utility model improves on the basis of conventional wrench.The one, the connecting portion 2 of wrench can stretch, and flexible amplitude is 0cm to 10cm, gear of every 2cm; The 2nd, the power part 3 of wrench also can stretch, and flexible amplitude is 0 cm to 20 cm, gear of every 5cm.Connecting portion 2 is 90 degree angles with power part 3, like this screw dismounting rotation is carried out outward by changing in casing at casing, according to the thickness of casing, can adjust the length of connecting portion, according to the size of revolving force, length that can motivation of adjustment portion, due to accessible in rotation, can rotate to arbitrarily angled, do not need wrench repeatedly to adjust, solved crawl space and operated inconvenient problem.
The utility model is simple in structure, is easy to preparation, by the connecting portion of spanner 2 and power part 3 are designed to telescopic right-angle structure, makes spanner can adapt to different spaces, and the requirement of different length has improved the utilization rate of spanner greatly, has improved operating efficiency.
