The above results explanation：The integrated handle stretching maximum, force of raw material production of the present invention, tensile strength, break-draw should
Become and be significantly larger than conventional sectional formula handle with load-bearing maximum, force.Handle pliability that conventional PE, PP raw material is molded into, stretching
Performance cannot meet the needs of existing product.Conventionally, easily occur coming off, break during lower assembly type handle carrying heavier product
Split.Conventionally, lower assembly type handle must employee assembling after just can be used, and integrated handle can then remove from assemble this ring
Section.
It can be seen from the above description that the above embodiments of the present invention realize following technique effect：
1) solve the problems, such as that integrated handle is difficult to practical application.
2) solve the problems, such as separate type handle coming off when putting forward heavier product.
3) reduce the process of handle above and below man-made assembly in production process, reduce production cost.
The foregoing is only a preferred embodiment of the present invention, is not intended to limit the invention, for the skill of this area
For art personnel, the invention may be variously modified and varied.Within the spirit and principles of the invention, that is made any repaiies
Change, equivalent substitution, improvement etc., should all be included in the protection scope of the present invention.
