A power bank is an external battery for your device when you are unable to charge and need to charge a device.

battery poked accidentally, is it safe to use?

Beetle flix 20K power bank was working fine, except its switch on the side sunk inside, so i tried prying it open and accidentally poked the battery by a screwdriver, that spot is giving sparks even when touched with hand or screwdriver, gives out burning smoke. Power bank is working fine. Can i just apply tape and continue to use it? In fact sparks came out even while applying tape and burnt it a bit.

No, it is unsafe to use any lithium ion battery if it is at all damaged. The battery should be disposed of in a safe manner.
