This is a charging stand for Philips 5000 series (specifically S5582/20) electric shavers. The design uses a sleeve to clamp the cable.
Please check that your charger plug is the same as that shown in the image. If it is different, then it may not fit.
It uses a brass insert and a 10-12mm m3 screw to hold the cable sleeve.
