When you pasted the commands into the shell, for how long did they run? Seconds? Minutes? Hours?

dd if=/dev/disk3 of=/dev/disk2 bs=131072

The above line says to read the contents from whatever is considered disk3 and write them onto what is marked as disk2. Since your TM disk appear to be called disk2 now, it was most likely partially or completely overwritten.

Any overwritten data is 100% gone. If only some data in the beginning of the drive was overwritten, there are different recovery softwares available that can potentially rescue data that wasn't overwritten.

For future reference, do not just paste commands into the Terminal without being 100% sure what you're doing.

i tried to use a recovery data soft but the external hard drive don t show up
is thier any solution left?

You are probably out of luck. An expensive data recovery firm might be able to retrieve something, possibly.

Just to exhaust all possibilities - Issue the following command in Terminal, and post the output:

diskutil list

The command will list all disks and all of their partitions.
