1. Change the shape of the surface of the plastic handle, for example, to make the handle relatively thinner to improve the stiffness and bending resistance of the handle. The longitudinal groove can well eliminate the possibility of deviation or deformation of the plastic handle under load.

2. Make the thickness of the plastic wall uniform, try to make the shape of the handle symmetrical, reduce extreme stretch points, and use arcs for excessive areas.
