对原本进行如下改进：

1.把原先的头部改成了更长、更霸气的鳄鱼嘴夹子，更容易抓住物体；

2.原版打印后转轴处容易出现断裂，所以在转轴处改为100%填充，使之不容易断裂。

The following improvements have been made to the original:

1. The original head has been changed to a longer and more domineering crocodile mouth clip, which makes it easier to grasp objects;

2. The original is easy to break at the hinge after printing, so it is changed to 100% filling at the hinge to make it not easy to break.
