Wherein the drawings are for illustrative purposes only and are shown in schematic, non-physical, and not intended to be limiting of the present patent; it will be appreciated by those skilled in the art that certain well-known structures in the drawings and descriptions thereof may be omitted.
As shown in fig. 1, 2 and 3, the novel locking mechanism comprises a supporting seat 1 and a buckle 2, wherein a rectangular through groove 6 is formed in the front side surface of the supporting seat, the rectangular through groove 6 penetrates through the top surface and the bottom surface of the supporting seat, and an abdication slope 7 communicated with the rectangular through groove is formed in the rear side top surface of the rectangular through groove 6 downwards; the buckle 2 is respectively provided with a horizontal arm 2-1 and an inclined arm 2-2 which are connected into a factory shape, the inclined arm 2-2 of the buckle is rotatably arranged in the rectangular through groove 6 through the rotating shaft 3, the rotating shaft 3 is sleeved with the torsion spring 4, and the horizontal arm 2-1 of the buckle is positioned above the top of the supporting seat 1 and is close to but not close to the top of the supporting seat. Here, the yielding ramp 7 plays the role of yielding the factory-shaped connection part of the buckle, and of course, the yielding ramp can also be ground into an arc shape adapted to the factory-shaped connection part of the buckle.
Fig. 1-3 show the natural state of the buckle under the action of the torsion spring without the action of external force, and at this time, the top surface and the adjacent end surface of the buckle inclined arm 2-2 naturally extend under the action of the torsion spring. When the clamp is used, the horizontal arm of the buckle is stirred upwards, the inclined arm rotates downwards to the rectangular through groove, the sheath is not influenced to be placed in the profiling cavity, after the sheath is placed in the profiling cavity, the horizontal arm is released, under the action of the torsion spring, the inclined arm naturally stretches out, the top surface of the inclined arm and the bevel ends 2-21 of the adjacent end surfaces are abutted against the outer side wall of the sheath, the sheath is pressed forwards, the sheath is abutted against the front side surface inside the profiling groove to realize locking, and the bevel ends are arc bevel ends. Compared with the prior latch hook cylinder which rotates downwards to the bayonet to form a horizontal shape to realize the downward pressing locking, the latch mechanism compresses the fixed sheath from the side surface, and is relatively more suitable.
In this embodiment, for aesthetic appearance, the torsion spring 4 is installed in such a way that the inclined bottom surface of the buckle inclined arm 2-2 is provided with a groove 2-22, and the torsion spring 4 is disposed in the groove 2-22.
