How to change the drill bit of an electric drill?

The steps for replacing the drill bit of an electric drill are as follows:
Prepare relevant tools, such as drill bits that need to be replaced, drill keys, etc., and unplug the power plug or turn off the power switch to ensure that there is no danger when replacing the drill bit.
Grasp the handheld drill tightly with one hand, and hold the gourd mouth of the drill or press the button at the tail of the drill with the other hand. Use force or rotate clockwise to expose the hole or clamp for installing the drill bit.
Take out the drill bit to be installed, place it in the exposed hole at the front end of the handheld drill, and rotate it clockwise by hand to clamp the drill bit. When pushing the drill bit, you should hear a slight “groove” sound.
Adjust the depth position of the stuck drill bit into the hole, and tighten it clockwise with a special key or wrench to lock it in place.
Plug in the power cord of the handheld drill, turn on the plug, idle for 2 seconds, and observe whether the drill bit of the handheld drill is securely installed.
Attention: When replacing the drill bit, make sure that the new drill bit matches the specifications of the electric drill to avoid damaging the electric drill or drill bit. At the same time, be careful and cautious during operation to avoid injury. If you are unsure how to replace the drill bit, it is recommended to seek professional help to replace it.
