## Abstract

A binding device for pulling tight a belt comprises a first ratchet wheel and a second ratchet wheel, each having a plurality of mounting openings, a roll, having a plurality of roll sectors that are respectively mounted in the mounting openings of the first and second ratchet wheels, of which at least one roll sector is removable, a lever, connected with the first ratchet wheel, a frame, connected with the second ratchet wheel; an upper blocking assembly, mounted on the lever, blocking the first ratchet wheel from turning, and a lower blocking assembly, mounted on the lever, blocking the second ratchet wheel from turning. Due to removability of one of the roll sectors, the belt is easily mounted and dismounted, and a wide range of applications is provided for.

## Claims

### Claim 1

A binding device, comprising:
a first ratchet wheel and a second ratchet wheel, each having a plurality of mounting openings;
a roll, further comprising a plurality of roll sectors that are respectively mounted in said mounting openings of said first and second ratchet wheels, with at least one roll sector being removable;
a lever, connected with said first ratchet wheel;
a frame, connected with said second ratchet wheel;
an upper blocking assembly, mounted on said lever, unidirectionally blocking said second ratchet wheel from turning; and
a lower blocking assembly, mounted on said lever, unidirectionally blocking said first ratchet wheel from turning;
wherein each of said roll sectors are axially removable independently of the other roll sectors; said roll comprises two roll sectors which each have a free end and are fixed to each other by a compound fixing assembly; and
wherein said compound fixing assembly further comprises
a transverse hole, passing through said free end of said first roll sector; a first fixing hole, passing through said free end of said first roll sector, oriented perpendicularly to said transverse hole;
a second fixing hole, passing through said free end of said second roll sector and aligned with said first fixing hole;
two first pins, entering said transverse hole from opposite ends thereof;
a handle, having a U shape and having ends to which said first pins are respectively attached, so that said first roll sector is readily manually moved, having lever holes close to said ends thereof;
a connecting piece, having a U shape and having ends with end holes, through which second pins pass, which in turn pass through said lever holes; and a bolt, passing through said first fixing hole of said first roll sector and having a free end with a mounting hole, passed through by said connecting piece.

### Claim 2 (depends on 1)

The binding device of claim 1, wherein said first and second ratchet wheels each comprise an inner half with an inner protrusion and an outer half with an outer protrusion.
