That appears to use a pass thru design on the socket end.
The two major pass through socket drive types are a spline design sold by Gearwrench, but also used by some other brands, I think including Husky, and a hex design that is sold by Kobalt in the USA, bit also used by a bunch of different brands.
I presume there are two major manufacturers making the two types and just rebranding them for different tool brands and companies.
The Hex type can have different variations in retaining method for the sockets, so the sockets aren’t always interchangeable.
There are also different drive sizes, and the socket sizes available for the drive sizes tend to correspond to the 1/4”, 3/8”, and 1/2” socket sizes.
The Kobalt sockets are branded Kobalt Xtreme Access.
The Gearwrench sockets are usually branded Pass-Thru.
Stanley has sold variations of the hex drive type under the Bostich brand.
