In a belt buckle device including a tongue piece (75, 76; 210; 310) connected to an end of a belt extending in a longitudinal direction and a hook member (68, 70; 220; 320) configured to be selectively connected to the tongue piece by engaging a first lateral bar of the tongue piece in a hook opening (111; 226; 326) defined by a hook portion (71, 72; 225; 324) thereof, a longitudinal dimension (B) between the free end of the tongue piece and a base end side of the first lateral bar is substantially equal to or smaller than a width (A) of the entrance of the hook opening, and the effective thickness (C) of the first lateral bar is greater than the width (A) of the entrance of the hook opening. Thus, the first lateral bar is held inside the hook opening as long as the tongue piece is kept in a flat position in a reliable manner. In particular, the first lateral bar can be freely introduced into the hook opening simply by raising the base end of the tongue piece while the first lateral bar is applied to the entrance of the hook opening so that the belt buckle device can be readily fastened even when the belt buckle device cannot be viewed from a proper viewing angle. Also, the belt buckle device can be readily fastened with a minimum dexterity requirement and very quickly.

The invention discloses a cable terminal tightening device. The cable terminal tightening device comprises a tightening device and a tightening wire clip, wherein the tightening device comprises a wire pressing body, a movable press block and a pressing screw rod; the wire pressing body comprises a connecting part and a support part; the movable press block is arranged between the connecting part and the support part through the pressing screw rod and is only performed with the linear movement between the connecting part and the support part; the tightening wire clip comprises a male clip, a female clip and a locking device; the male clip and the female clip are tightly matched with the movable press block and the support part; in the use process, a bent cable terminal is arranged between the male clip and the female clip, and then the pressing screw rod is rotated to enable the movable press block to move relative to the support part until the cable is pressed under the matching action of the male clip and the female clip; the male clip, the cable and the female clip are locked together through the locking device; finally, the pressing rod is reversely rotated to disengage the tightening wire clip from the tightening device. The cable terminal tightening device has the advantages that the cable terminal can be quickly tightened, the fixing efficiency of the cable terminal is greatly improved, the firmness is good, the structure is simple, and the universality is good.
