Abstract
The utility model discloses an effort-saving wrench for vehicle, which is a tool for vehicle, comprising a socket wrench, a boosting rod and a roller unit. The effort-saving wrench for vehicle can be used for unscrewing the screw nuts or screw bolts of wheel ribs on the driving wheels of the vehicle via the dynamic force of the vehicle, and when the screw nuts of the driven wheels of the vehicle are disassembled, the effort-saving wrench for vehicle can act on saving labor.
Description
Automobile is with the car labour-saving spanner, and the utility model belongs to automobile or other self-propelled vehicle driver's tool.When automobile needed changing of tire on the way at present, dismounting spoke nut or bolt relied on manpower fully, and these nuts or bolt are too tight, and driver's labour intensity is too big, and the utility model is exactly for addressing this problem design-calculated.
The utility model is to utilize the power of driving engine to unscrew the nut or the bolt of driving wheel, and for flower wheel, it can play boosting-rod.
The utility model is made up of socket wrench 1, boosting-rod 3 and wheel group three parts.The structure of socket wrench 1 is shown in figure one, and it is present existing driver's tool, on the socket wrench 1 porose 2.The structure of boosting-rod 3 is shown in figure two, and it is a stock, and left end neck 4 is thinner, can be inserted in the hole 2 of socket wrench 1, and its right-hand member is shaped on breach 6.For the ease of carrying, boosting-rod 3 also can be made removable two sections.Wheel group such as figure two, it is that the two ends of a little axle 7 put two wheels 8, and makes axial restraint with nut 9, is shaped on step 10 on the little axle 7, during assembling, need only be the breach 6 of little axle 7 insertion boosting-rods 3, the screw down clips jack panel 11 then.
Tear spoke nut on the driving wheel (or bolt) open shown in figure three, four, the steps include: the first, the automotive wheels that jack-up will be torn open makes it liftoff.The second, shown in figure two, install the utility model, allow nut 12(or the bolt that will tear open) forward near the H of position, socket wrench 1 is enclosed within on the nut 12, buttress the M place lightly with hand.The 3rd, fire an engine makes the automotive wheels that will tear open change rotation with per minute 2 to 5.When nut 12 forwarded T place shown in the figure three to, this nut had been unscrewed certain angle.At this moment depress power-transfer clutch, cut off power, socket wrench 1 is taken off from nut 12, be enclosed within again on the nut that the next one will tear open.
When split nut or bolt were right-hand thread, the rotation direction of installation of the present utility model and automotive wheels was shown in figure three; When being left-hand thread, then install by figure as split nut or bolt.(seeing figure five)
When tearing the flower wheel upper nut open, unscrew nut 11 earlier the wheel group is taken off from the breach 6 of boosting-rod 3.Rely on manpower to unscrew nut, the utility model plays boosting-rod.
