When the clamping plate 2 needs to be detached from the base 1, the clamping plate 2 drives the elastic element 3 to slide out of the sliding rail 13 to the bump 351 to be abutted against one side wall of the limiting groove 4 by pressing the tail elastic plate 31 after the fixed block 5 is separated from the limiting groove 4, and then a tool slides into the limiting groove 4 to press the bump 351 downwards, so that the clamping plate 2 drives the elastic element 3 to be completely separated from the sliding rail 13, and the detachable function of the elastic element 3 and the base 1 is realized.
The bending degree of the first elastic rib and the bending degree of the second elastic rib are semicircular.
By adopting the structure, the elastic force of the first elastic rib and the second elastic rib can be improved, and the elastic range of the first elastic rib and the second elastic rib can be improved, so that the first elastic rib and the second elastic rib can be further prevented from being broken, and the movable clamping plate 34 can be conveniently clamped with the guide rail.
The present invention further provides that the two sides of the movable clamping plate 34 are provided with limiting blocks 341 at intervals at positions corresponding to the second flaring 333, and the limiting blocks 341 are located in the chute 21.
In the above structure, the limiting block 341 is arranged to facilitate limiting the elastic piece 3, so that the stability of the elastic piece 3 is improved, the elastic force between the movable clamping plate 34 and the elastic ribs 33 is improved through the spacing arrangement of the limiting block 341 and the second flaring 333, and the limiting block 341 is conveniently arranged in the chute 21, so that the stability of the elastic piece 3 is improved, and the reliability of the invention is improved.
The invention is further arranged that the end surface of the movable clamping plate 34 is provided with an inclined block 342 which is inclined upwards and outwards relative to the clamping plate 2.
By adopting the structure, the inclined block 342 can be matched with the guide rail, so that the movable clamping block can slide to the upper part of the guide rail, the movable clamping plate 34 can be conveniently matched with the guide rail, and the convenience in installation is improved.
The invention is further arranged that the bottom of the clamping plate 2 is upwards protruded at the position corresponding to the bottom of the tail spring plate 31 to form a stop table 23.
With the adoption of the structure, the tail spring plate 31 can be limited, and the tail spring plate 31 is prevented from being bent excessively to be broken, so that the stability of the elastic piece 3 is improved, the maintenance cost is reduced, and the reliability of the invention is improved.
The foregoing is merely a preferred embodiment of the present invention, and it should be noted that it will be apparent to those skilled in the art that modifications and variations can be made without departing from the technical principles of the present invention, and these modifications and variations should also be regarded as the scope of the invention.
