A buckle with a string adjustment portion includes a plug and a socket. The plug includes: a tightening string member attachment portion configured to slidably lock a string member and adjust a length of the string member; and leg portions which are inserted into and engaged with the socket. The socket includes a fitting portion including an insertion opening. An insertion hole through which the string member is inserted is formed to penetrate the tightening string member attachment portion, and a portion connecting the leg portions side of the insertion hole serves as a second bar. The second bar is located on an insertion direction side of the leg portions with respect to a position where an end portion of the plug and the insertion opening of the socket are abutted against each other, in a state where the leg portions are engaged with the socket.

A hand strap and a hand controller assembly are provided. Two ends of the hand strap are respectively used for connecting a hand controller. The hand strap includes an elastic strap, a belt body, and a locking mechanism. The locking mechanism includes a fixed assembly and a sliding assembly. 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. 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.

A buckle component (1, 2) having a main body (3) and a clamping web (4), the main body (3) having a belt-receiving opening (5), and the clamping web (4) being mounted displaceably on the main body (3) in the belt-receiving opening (5) for clamping a belt (6), which is guided around the clamping web (4), between the clamping web (4) and an edge (7) of the main body (3) bounding the belt-receiving opening (5). The buckle component (1, 2) additionally has a flap (8) which is mounted pivotably on the main body (3) by a pivot joint (9), and the flap (8) has a clamping surface (10) for clamping the belt (6) between the clamping surface (10) of the flap (8) and the clamping web (4) in a clamping position of the flap (8).

The bungee fastener has a tapered chute that accepts a locking slider. A channel forms an opening in a side of the body thereby allowing passage of the slider through the channel. A plurality of slider teeth along a portion of the slider within the tapered chute may lock onto a bungee when the slider is slid into a locked position. The slider moves along the channel, thereby selectively narrowing the tapered chute with the slider teeth as the slider is slid into the locked position and enlarging the tapered chute as the slider is slid into the unlocked position. The bungee fastener may include a single slider or a plurality of sliders.

A clip-on belt buckle, including a buckle part and a connecting part. A fixed end of a belt is fixedly connected to the connecting part. The buckle part comprises a buckle body, a first clamp plate and a second clamp plate. An upper end and a lower end of the buckle body are provided with an oblique hole, respectively. An upper part and a lower part of a back of the buckle body are provided with a sliding groove, respectively. Centers of an upper end and a lower end of the first plate are provided with an elongated hole along a front-and-back direction, respectively. A vertical shaft is provided at a middle of the second plate. Two ends of the vertical shaft extend through the elongated holes, and then extend through the oblique holes. A movable end of the belt is inserted between the first plate and the second plate.
