Abstract
The utility model discloses a labor -saving wrench, the novel nipple rectifier comprises a cylindrical shel, the barrel outer wall is along radially being equipped with support arm A, and a support arm B and support arm A are articulated, and its articulated shaft is parallel with cylinder axis, is equipped with the spike on support arm B, the spike central line is the disalignment with the articulated shaft. The utility model discloses a labor -saving wrench, the spike is realized articulating with the barrel, and the distance is adjustable, has increased application range, can match more multi -vehicle type's tire.
Description
Technical field
The utility model relates to a kind of labour-saving spanner.
Background technology
Labour-saving spanner, is generally used for that heavy vehicle unloads tire, dismounting nut when changing tire.Labour-saving spanner on existing market comprises cylindrical shell, planet carrier gear group and spike, in use, by the jacket casing with lug nut corresponding specification on the square tenon of spanner output shaft, the other end of sleeve entangles the nut treating dismounting, the spike of labour-saving spanner is shelved on adjacent nut, the direction that spike is shelved is contrary with the hand direction of dismounting nut, nut can be turned on by the labour-saving spanner of this structure very easily, but, there is also some defects: the distance between the spike center line of existing labour-saving spanner and tubular axis is for immobilizing, that is: the nut distance that the nut of sleeve dismounting and spike are shelved is invariable, in actual use, a kind of labour-saving spanner of specification only can be used on the wheel hub with its parameter matching, or, if the nut shelved needed for spike produces deformation or is blocked by foreign matter, labour-saving spanner does not just play effect, also have, due to the constant distance between spike center line and tubular axis, after the complete nut of dismounting, need spike and sleeve to leave nut simultaneously, just can carry out the dismounting of next nut, very loaded down with trivial details.
Summary of the invention
The utility model will solve the technical problem that existing labour-saving spanner uses underaction.
The technical scheme in the invention for solving the above technical problem is:
The utility model discloses a kind of labour-saving spanner, comprises cylindrical shell, and described cylinder body outer wall is radially provided with support arm A, and a support arm B and support arm A is hinged, and its jointed shaft is parallel with tubular axis, and support arm B is provided with spike, and described spike center line and jointed shaft are disalignment.
Described support arm A comprises two panels spaced arm unit up and down, and support arm B is embedded in two panels and props up between arm unit, and realizes being fixedly hinged by screw.
The technique effect that the utility model can reach is:
Compared with prior art, laborsaving wrench of the present utility model, realizes the variable of spike axis and tubular axis distance by the articulated structure of support arm A and support arm B, in use, can change distance flexibly, expand the scope of application.
Accompanying drawing explanation
Fig. 1 is stereogram of the present utility model.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Refer to Fig. 1, the utility model provides a kind of labour-saving spanner, comprises cylindrical shell 1, described cylindrical shell 1 outer wall is radially provided with support arm A2, and a support arm B3 and support arm A2 is hinged, and its jointed shaft 4 and cylindrical shell 1 axis being parallel, support arm B3 is provided with spike 5, and described spike 5 center line and jointed shaft 4 are disalignment.
Support arm B3 can turn an angle around jointed shaft 4, like this, distance between the center line of spike 5 and the axis of cylindrical shell 1 realizes adjustable, like this, between spike 5 center line and cylindrical shell 1 axis distance can produce a minimum range and a ultimate range, formed between its minimum range and ultimate range centered by cylindrical shell 1 axis line annular region in nut, spike 5 can it be all impetus.
Described support arm A2 comprises two panels spaced arm unit up and down, and support arm B3 is embedded in two panels and props up between arm unit, and realizes being fixedly hinged by screw.
Described spike 5 is one-body molded with support arm B3.
Below the use principle of labour-saving spanner of the present utility model is made an explanation:
1, by the jacket casing with lug nut corresponding specification on the square tenon of spanner output shaft, the other end of sleeve entangles the nut treating dismounting, be shelved on by the spike of labour-saving spanner on the nut being applicable to putting forth effort, the direction that spike is shelved is contrary with the hand direction of dismounting nut.2, user according to nut specification, can select different compliant sleeves, as back gauge 22,27,30,32,33,35,38,41 millimeters etc.3, after this product utilization gear combination is slowed down, the principle that the moment transmitted is amplified in proportion, can make output torque increase decades of times, thus only need shake rocking bar just dismantled and assembled heavy truck tires nut like a cork.4, during dismounting lug nut, rocking bar shaking direction is identical with nut turn direction.5, when nut loosening, use extension bar instead, be directly enclosed within one end of extension bar with rocking bar, jacket casing, just can promptly dismounting nut at the other end of extension bar, when feeling that feel is heavier with extension bar, use labour-saving spanner instead, is convenient to nut dismounting.6, when the nut of dismounting is in darker position, by spreading jacket casing on the power shaft of spanner, labour-saving spanner length can be which increased, avoid rocking bar in use to encounter tire.
Above a kind of labour-saving spanner that the utility model embodiment provides is described in detail, apply specific case herein to set forth principle of the present utility model and embodiment, the explanation of above embodiment is just for helping to understand the technical scheme that the utility model discloses; Meanwhile, for one of ordinary skill in the art, according to thought of the present utility model, all will change in specific embodiments and applications, in sum, this description should not be construed as restriction of the present utility model.
