[0002] With the continuous development of science and technology, new energy self-driving cars are increasing, and charging piles that can power them have become an indispensable part. DC charging piles can directly power the power batteries of electric vehicles, also known as "fast charging", which can provide sufficient power and have a large adjustment range for the output voltage and current, and can meet the requirements of fast charging. However, during the placement process of traditional DC charging piles, there is no clamping mechanism for the power cord, which may cause the power cord to be too long and inconvenient to store or the power cord to be damaged by pressure, which brings inconvenience to people. Therefore, in response to the above problems, it is necessary to design a new portable DC charging pile with a clamping mechanism. Utility Model Content

A power cord 9 for power transmission is provided on the back of the pile body 12, and a connecting handle 7 for conveniently taking the power cord 9 is provided on the side of the power cord 9 away from the pile body 12, and a charging connector 6 is provided on the top of the connecting handle 7. The power cord 9 uses imported APEX outer sheath material and supports outdoor use. A clamping mechanism for fixing the power cord 9 is provided on one side of the thickened outer shell 2. The clamping mechanism is not only easy to operate, but also can well clamp and fix the power cord 9.

[0018] The clamping mechanism includes a placement block 16 fixedly connected to one side of the thickened shell 2 and a connection block 15 interlaced with the outer wall of the placement block 16. The interlaced connection between the placement block 16 and the connection block 15 can well fix the clamping mechanism and facilitate replacement when the clamping mechanism is damaged.
