The groove walls on both sides of the spacing groove 52 are inclined surfaces as required, which facilitates the end of the tightening element 4 to enter and leave the spacing groove 52.

Therefore, the utility model provides a coupling mechanism can realize quick installation and dismantlement, and at the installation with dismantle the in-process, the peg graft post is along rectilinear movement, and required space is little, easy dismounting.

In one embodiment, as shown in fig. 2 and fig. 8 to 9, an elastic member 6 for driving the sliding barrel 3 to move toward the main body structure 5 side is connected between the mounting seat 1 and the sliding barrel 3. The elastic member 6 is used for driving the sliding cylinder 3 to return to the initial position so as to automatically press the abutting element 4. When the slide cylinder 3 is brought to slide toward the mount 1 side, the elastic member 6 is compressed. After the acting force on the sliding cylinder 3 disappears, the sliding cylinder is automatically reset under the action of the elastic piece 6.

The elastic member 6 may be an expansion spring or an elastic sheet.

In one embodiment, as shown in fig. 2 and 4-5, the tightening member 4 is a spherical ball.

The radius of the outside opening 211 of the cylindrical wall through hole 21 is larger than that of the spherical top bead, and the radius of the inside opening 212 of the cylindrical wall through hole 21 is smaller than that of the spherical top bead.

In this embodiment, the tightening element 4 is a spherical ball which is accommodated in the through hole 21 of the cylinder wall. The cylindrical wall through-hole 21 gradually contracts from the outside to the inside in the radial direction along the fixed cylinder 2. The outer opening 211 of the cylindrical wall through hole 21 faces the inner surface of the sliding cylinder 3, and the inner opening 212 of the cylindrical wall through hole 21 faces the center of the fixed cylinder 2. The radius of the outer opening 211 is greater than the radius of the spherical head bead which can be inserted from the outer opening 211 into the through-hole 21 of the cylinder wall. The radius of the inner opening 212 is smaller than the radius of the spherical top bead, which prevents the spherical top bead from falling off the inner opening 212. The diameter of the spherical top bead is greater than the distance between the inner opening 212 and the outer opening 211. Therefore, a portion of the spherical tip bead protrudes out of the outer opening 211 and can be pressed by the boss 32.
