I would say almost certainly not. It's appears to be designed to be used with the hook end downwards and the knurled screw attached to something. The key might be in the exact design of that screw end which we can't see. I would expect there to be a hole, or at least a dimple, opposite to the screw for the end of it to go into to make a secure attachment to something like a flat plate with a hole in that.
It would also help to know what the scale is graduated in. Pounds, ounces, kg etc.
Forget that enquiry. It's almost certainly pounds. I can see enough of the spring to deduce from scaled measurements of the photos based on your approx length of 7" for the item that the compression spring has an o/d of about
20mm, a wire thickness of about 1.9mm, 12 or maybe 13 coils with the top two or three hidden from view and about 2" of travel between the 0 and 25 readings.Putting those data into my compression spring calculation program gives me a spring rate of about 12 lbs per inch which is exactly what we need for 25 lbs over 2 inches. If the scale were in ounces the spring wire would need to be much thinner and for kg somewhat thicker - about 2.3mm although that might just be within the limits of uncertainty based on such approximate measurements.
