Referring to FIGS. 2 to 4 , FIG. 2 shows a three-dimensional schematic diagram of the connection between the locking member, the handle and the elastic member in the first embodiment of the present invention, FIG. 3 shows the exploded schematic view of FIG. 2 , and FIG. 4 shows the 2 is a schematic cross-sectional view of the A-A direction. The handle 200 in this embodiment includes a socket portion 210 and an extension portion 220. The extension portion 220 is connected to the outer side wall of the socket portion 210 and extends along the radial direction of the socket portion 210. Extending out, an axial through hole 211 is provided inside the socket part 210 , the first end of the through hole 211 is a regular hexagonal hole, and the tail end is a circular hole. The hole wall of the regular hexagonal hole, that is, the inner wall of the socket portion 210 can be regarded as a plurality of limiting planes distributed along the circumferential direction. The diameter of the circumscribed circle of the regular hexagonal hole is not less than the diameter of the circular hole, that is, the intersection of the regular hexagonal hole and the circular hole has a stepped surface.

During connection, the socket part 210 is socketed on the rear end of the locking member 100 , specifically, the positioning part 130 is inserted into the regular hexagonal hole, the connection part 140 is inserted into the circular hole, and the connection part 140 and the circular hole are connected. There is a gap 201 between them, and the elastic member 300 is located in the gap 201. One end of the elastic member 300 abuts against the above-mentioned stepped surface, and the other end abuts against the screw 600 screwed in the threaded hole 141. Based on the above structure, the handle 200 can be positioned by positioning The mutual abutment between the plane 131 and the limiting plane drives the locking member 100 to rotate, and at the same time, the handle 200 can move relative to the locking member 100 in the axial direction. When the tail end moves, the elastic member 300 will be gradually compressed along with the movement of the handle 200 , and the compressed elastic member 300 can drive the handle 200 to reset after the external force driving the movement of the handle 200 disappears.

The elastic member 300 in this embodiment is a spring. In this embodiment, the handle 200 is sleeved on the rear end of the locking member 100, and the elastic member 300 is placed between the handle 200 and the sleeved part of the locking member 100, so as to reduce the volume of the entire locking device . In addition, in this embodiment, the elastic member 300 is fixed by the screw 600 screwed in the threaded hole 141 . After the screw 600 is unscrewed, the elastic member 300 and the handle 200 can be taken out in sequence. The structure is compact and easy to disassemble.

It can be understood that the limit planes in this embodiment correspond to the number of the positioning planes 131 .

Referring to FIGS. 5 to 7 , FIG. 5 shows a three-dimensional schematic view of the anti-releasing locking device according to the first embodiment of the present invention, FIG. 6 shows an enlarged schematic view of area B in FIG. 5 , and FIG. An exploded schematic diagram of the present embodiment, the anti-releasing locking device of this embodiment includes a first part 400 , a second part 500 , the locking member 100 , the handle 200 and the elastic member 300 of the above-mentioned first embodiment.

The first part 400 is provided with a threaded hole 410, the second part 500 is provided with a through hole 510 corresponding to the threaded hole 410, the second part 500 is provided with an annular flange 520 along the circumference of the through hole 510, and the flange 520 is provided with a ring-shaped flange 520. The notch 530, ie the flange 520, is an incomplete annular structure.

In use, the threaded portion 110 of the locking member 100 is passed through the through hole 510 and screwed into the threaded hole 410 until the stopper 120 abuts against the second part 500 . The handle 200 is placed in the notch 530 at the same time, the handle 200 can only swing in a small range within the notch 530 due to the abutting effect of the two ends of the flange 520. If the size of the notch 530 is set small enough, the handle 200 can even It can be stationary in the notch 530 , in this way, the locking member 100 cannot be rotated in the circumferential direction, thereby avoiding the loosening of the locking member 100 . When it needs to be disassembled, pull the handle 200 in the direction of the rear end of the locking member 100 (that is, upward) until the handle 200 goes over the flange. At this time, the handle 200 can rotate freely, so as to drive the locking member 100 out of the threaded hole. 410.
