Power tool

A power tool comprising:

• a working head assembly comprising a working head for operation;
• a power assembly configured to drive the working head;
• a battery pack configured to supply power to the power assembly;
• a gripping assembly for user gripping;
• and
• a connecting tube comprising a first connecting tube connected to the working head assembly and a second connecting tube connected to the gripping assembly,
• wherein:
• the first connecting tube and/or the second connecting tube is arranged with at least a first material layer made of carbon fiber material and a second material layer made of non-carbon fiber material in a radial direction thereof;
• a stiffness of the second material layer is smaller than a stiffness of the first material layer;
• and
• a toughness of the second material layer is greater than a toughness of the first material layer.

A power tool comprising:

• a working head assembly comprising a working head for operation;
• a power assembly configured to drive the working head;
• a battery pack configured to supply power to the power assembly;
• a gripping assembly for user gripping;
• a connecting assembly disposed between the working head assembly and the gripping assembly;
• and
• one end of the connecting assembly is provided with the working head assembly, another end thereof is provided with the battery pack, the power assembly and the gripping assembly, the connecting assembly comprising a first connecting tube, a second connecting tube and a handle tube, the handle tube is connected to the gripping assembly, the first connecting tube being closer to the working head assembly relative to the second connecting tube, the second connecting tube being connected to the first connecting tube, and the second connecting tube being closer to the gripping assembly relative to the first connecting tube,
• wherein:
• the first connecting tube is arranged with at least a first carbon fiber layer made of carbon fiber material in a radial direction thereof;
• the second connecting tube is arranged with at least a second carbon fiber layer made of carbon fiber material in a radial direction thereof;
• and
• a ratio of a total layer thickness of the first carbon fiber layer in the first connecting tube to a total wall thickness of the first connecting tube is greater than a ratio of a total layer thickness of the second carbon fiber layer in the second connecting tube to a total wall thickness of the second connecting tube.
