The utility model can disassemble and assemble the screw nuts of a tyre, riding loop screw nuts and other screw nuts in various directions. The height of the machine body can be adjustable. The utility model only has one power output shaft. The utility model is suitable for small-sized motorcades, small-sized salvage shops and individual repairers.
Description
The utility model relates to a kind of portable power tools, particularly a kind of all direction multifunctional nut changer.
Automobile tyre nuts such as dismounting automobile, ride and climb the work that nut is mechanic's labour intensity maximum.Chinese patent CN2093773U has announced a kind of lug nut, has ridden and climb the dual-purpose changer of nut, it by the changer main frame, ride and climb the nut mechanism for assembling-disassembling and ut socket is formed, the changer main frame is provided with upper and lower two power output shafts, cooperate with ut socket respectively to be used for the dismounting lug nut and to ride climbing nut, and adopt the bearing type clutch structure.The dual-purpose changer of this structure has solved weak points such as the noise that exists in the prior art is big, clutch is easy to wear, inefficiency effectively, can the dismounting lug nut, and again can dismounting ride and climb nut, but still have following weak point:
1, lug nut and riding of vertical direction that can only the dismounting horizontal direction be climbed nut, and nut that can not other direction of dismounting.2, complex structure, cost height are climbed upper and lower two power output shafts of nut owing to be respectively equipped with the dismounting lug nut and ride, so complex structure, the cost of manufacture height.
The purpose of this utility model is to overcome above the deficiencies in the prior art part and a kind of all direction multifunctional nut changer is provided.
The purpose of this utility model reaches in the following way: all direction multifunctional nut changer by the changer main frame, ride and climb nut mechanism for assembling-disassembling and three parts of ut socket, have on the power drive mechanism and can be multi-faceted climb the device that the nut mechanism for assembling-disassembling connects and have only a power output shaft with riding, the body elevating mechanism is installed below the body.
The utility model is owing to adopt as above design, compared with prior art, have following advantage: 1, a tractor serves several purposes: this machine not only is applicable to the dismounting of the lug nut of automobile, motor vehicle, and is applicable to ride and climbs the dismounting of nut and various machanical fastener nuts.
2, the nut to different azimuth can carry out dismounting: the nut that at present traditional wheel nut loader can only the dismounting horizontal direction, ride and climb the nut changer and be only limited to vertical nut in the dismounting, all can't dismounting to the nut in other orientation (following vertical nut, tiltedly nut etc.), the utility model has overcome the deficiency of present all kinds of nut changers, can carry out dismounting to the various nuts of different azimuth.
3, simple in structure, easy to manufacture, cost is low: this machine is compared with dual-purpose changer, has only a power output shaft, has reduced transmission noise and function loss effectively, alleviated the weight of complete machine, reduced the cost of complete machine, and making is simpler, uses more convenient flexible.
4, changer main frame adjustable height, is separated easily the combination of climbing nut mechanism for assembling-disassembling and changer main frame of riding, and the orientation is adjustable, thereby has improved the applicability of complete machine.
Below in conjunction with drawings and Examples detailed structure of the present utility model is further described.
