The 4th left pivot hole in hole, the second left pivot hole and upper left support arm；The third successively passed through in upper right support arm with right pivot is right
The first Right, the second Right on pivot hole, U-shaped hog frame and the 4th Right in upper right support arm, and with
Lock-screw external screw thread and the threaded hole of right pivot end form screw thread pair；The left pivot of formation is machined in left pivot small end
Second shaft shoulder of axis and axial limiting of the left pivot of left first shaft shoulder of pivot common implementing in upper branch arm assembly；Outside right pivot
Implement right pivot in upper branch arm assembly to be machined the axial limiting lug formed with the right pivot shaft shoulder and combine on cylinder
Axial limiting；It is equipped with the first oblique cutting slot of top on two side plate bodies on the component of top and the second oblique cutting slot of top respectively corresponds
Implement clearance fit in left pin circle column, the top arc-shaped slot being equipped with and top Thuban shaft through-hole correspond respectively to right pivot
Outside cylinder implements clearance fit.
Wherein, the outer end face that axially-displaceable momentum of the right pivot on upper branch arm assembly meets threaded hole being capable of the retraction right side
4th Right of upper branch arm entity, while meeting top arc-shaped slot and being rotatably inserted into right pivot outside cylinder implementation gap
Cooperation.
Wherein, asymmetrical frame top technology groove is offered in the top end part position of U-shaped hog frame.
Wherein, axially-displaceable momentum of the left pin circle column in upper branch arm assembly meets the first oblique cutting slot of top, top
The conformability of first second oblique cutting slot is inserted into.
Wherein, the nominal radius of the center cambered surface of arc-shaped slot is come directly towards equal to the right pivot and left pivot in upper branch arm assembly
The axis center of axis away from.
The utility model is had the beneficial effect that compared with prior art by the way that traditional upper branch arm component to be decomposed into
Upper branch arm assembly and top component simultaneously form each geometric element of quick convenient disassembly and assembly structure, greatly facilitate identical upper branch arm
Assembly is assembled different style tops component by permutation and combination respectively, is reduced manufacturing process cost, is also substantially improved automobile factory
Free assembling of the various different automobile types of institute's production and sales to top component, so it facilitates terminal user and chooses a variety of style tops
After head part using same jack ontology carry out applicability replacement top it is preferable to use.
