The utility model provides a rivet that fastening is effectual, includes outer sleeve 1 and along the inner skleeve 3 of 1 axis direction slip of outer sleeve and swivelling joint, first internal thread has been seted up to inner skleeve 3 inner chamber, realizes the straight line through spacing post 31 and the cooperation of spout 6 between outer sleeve 1 and the inner skleeve 3 and slides, and spout 6 outwards extends and is provided with spacing groove 7 more than two sets of.

Furthermore, the sliding groove 6 is arranged on the outer sleeve 1, and the limiting column 31 is arranged on the outer wall of the inner sleeve 3.

Furthermore, a plurality of groups of limiting grooves 7 are arranged along the length direction of the sliding groove 6 and are alternately distributed on two sides of the sliding groove 6.

Furthermore, the structure of the limiting groove 7 is L-shaped.

Furthermore, a second internal thread is arranged at the cap head 2 of the outer sleeve 1, a clamping block 4 in threaded connection with the second internal thread is arranged, and a spring 5 is arranged on one side, located in the inner cavity of the outer sleeve 1, of the clamping block 4.

Further, the first internal thread and the second internal thread are opposite in spiral direction.

One embodiment of the utility model:

the upper end and the lower end of the outer sleeve 1 are mutually penetrated, first internal threads which are mutually penetrated are arranged between the upper end and the lower end of the inner sleeve 3, the inner sleeve 3 is in a circular structure in appearance, the inner cavity of the outer sleeve 1 is in a circular structure, and the first internal threads of the inner cavity of the inner sleeve 3 are used for being in threaded connection with an external screw; the inner sleeve 3 is in linear sliding fit with the inner cavity of the outer sleeve 1 along the axis of the outer sleeve, the outer sleeve 1 is provided with a sliding groove 6, the outer wall of the inner sleeve 3 is provided with a limiting column 31, and the limiting column 31 is in linear sliding fit with the sliding groove 6, so that the inner sleeve 3 is guided to linearly slide relative to the outer sleeve 1 along the axis direction of the outer sleeve and cannot be separated;

the sliding groove 6 is provided with a limiting groove 7 of an L-shaped structure in an outward extending manner, the arrangement of the limiting groove 7 is as shown in FIG. 2, after the limiting column 31 moves to the position of the limiting groove 7 in the sliding groove 6, the inner sleeve 3 rotates relative to the outer sleeve 1, so that the limiting column 31 moves to the limiting groove 7; the limiting column 31 moves to the limiting grooves 7 at different positions to realize the adjustment of the length of the rivet formed by the inner sleeve 3 and the outer sleeve 1.
