Detailed Description
Referring to fig. 1-5, embodiments of the present utility model are further described;
A C-shaped buckle comprises a main body 1, a nut 2 which is positioned at the top of the main body 1 and is integrally formed with the main body, and a plurality of pairs of back-off buckles 3 which are fixed on the outer side of the main body 1, wherein the main body 1 is matched with an automobile mounting hole, and after the main body 1 is inserted into the mounting hole, the back-off buckles 3 are tightly attached to the inner wall of the mounting hole so as to achieve the fixing effect;
The upper fixing groove 13 and the lower fixing groove 9 which are communicated are respectively formed in the upper and lower parts of the inside of the main body 1, the inner screw threads 14 are formed in the inner wall of the upper fixing groove 13, the embedded column 8 is arranged between the inner parts of the fixing groove 13 and the lower fixing groove 9, the outer screw threads 11 matched with the inner screw threads 14 are formed in the outer side of the embedded column 8, the embedded column 8 and the upper fixing groove 13 are in a detachable connection mode (screw connection), firstly the embedded column 8 is convenient to install and position in the upper fixing groove 13, secondly when the main body 1 is detached from an installation hole, the embedded column 8 is rotated upwards to enable the upper end of the embedded column 8 to protrude out of the top of the main body 1, so that a force exerting part is applied when the main body 1 is detached, then the embedded column 8 is pulled upwards, a worker can detach the main body 1 from the installation hole, and because the lower end of the embedded column 8 is in interference fit with the lower fixing groove 9, the main body 1 is stretched out after the embedded column 8 completely enters the lower fixing groove 9, the inverted buckle 3 is more tightly attached to the installation hole, so that the installation of the main body 1 is more firm, the top of the embedded column 8 is integrally formed with the head 6, the head 7, the cross groove 7 is formed on the head, and the cross groove 7 is convenient for the worker to rotate the embedded column 8.
