It doesn't work at all! Repair the junk electric screwdriver!

Repair the electric screwdriver RAQUL VP-851D from a company called VOICE.
Rakuru is the driver's name, not the company name!
It doesn't work at all even if it is charged.
I would like to compare it with the REZLINK electric screwdriver that you can buy at Komeri when it starts to work.
The operation method is different, but the shape is very similar to Vessel's electric dora ball!
