Hand strap and hand controller assembly

A hand controller assembly comprising:

• a hand controller having a top and a bottom opposite to each other;
• and
• a hand strap, having two ends respectively adapted for connecting to the hand controller, the hand strap comprising:
• an elastic strap coupled to the bottom;
• a belt body having a first end and a second end opposite to each other, wherein the first end is coupled to the top of the hand controller;
• and
• a locking mechanism disposed at the second end and coupled with the elastic strap, wherein the belt body is coupled to the bottom via the locking mechanism and the elastic strap, and the locking mechanism comprises:
• a fixed assembly;
• and
• a sliding assembly, wherein when a relative position of the fixed assembly and the sliding assembly is in a locked state, the fixed assembly and the sliding assembly clamp and fix the elastic strap;
• when the relative position of the fixed assembly and the sliding assembly is in an unlocked state, the fixed assembly and the sliding assembly release the elastic strap;
• and when the elastic strap is not subjected to an external force, an elastic force of the elastic strap drives the relative position of the fixed assembly and the sliding assembly to be maintained in the locked state.
