2、 If you don't know how to release the original blade, you can observe in the picture below that the head of a typical electric screwdriver has a shaft cap. Use a little force to hold it back, or press it down with your fingers. There is a steel ball inside, and when it pops out, the shaft center can be exposed.
3、 Finally, align the rear end of the new blade with the bottom of the slot, insert it into the slot, and then release the shaft cap. Hearing the sound indicates that the installation is complete.
