[0028] It is easy to understand that according to the technical solution of the utility model, without changing the essential spirit of the utility model, a person skilled in the art can propose a variety of interchangeable structural modes and implementation modes. Therefore, the following specific implementation modes and drawings are only exemplary descriptions of the technical solution of the utility model, and should not be regarded as the entirety of the utility model or as a limitation or restriction to the technical solution of the utility model.

[0029] Example 1

[0030] See also Figure 1-3 This embodiment introduces a plug-in quick-release structure, which is mainly composed of an outer sleeve 1, an inner rod 2, a stopper 3, and a conical ring 4. A longitudinal groove 11 is axially provided at the top of the inner wall of the outer sleeve 1, and the bottom end of the longitudinal groove 11 extends transversely along the inner circumference of the outer sleeve 1 to form a transverse groove 12. The end of the transverse groove 12 away from the longitudinal groove 11 is the terminal end and a stopper groove 13 is longitudinally provided on the side. It should be noted that the stopper groove 13 does not extend to the bottom end of the outer sleeve 1, and maintains a fixed distance from the bottom end of the outer sleeve 1.

[0031] The diameter of the inner rod 2 is adapted to the inner diameter of the outer sleeve 1. In order to facilitate the bottom end of the inner rod 2 to enter the outer sleeve 1, the bottom end of the inner rod 2 gradually reduces in diameter from top to bottom to form a cone, so as to facilitate the inner rod 2 to enter the inner sleeve 1. The outer wall of the inner rod 2 is provided with a slider 21, which is located above the tapered part of the inner rod 2, and the slider 21 is adapted to the longitudinal groove 11 and the transverse groove 12, that is, the length of the slider 21 is adapted to the width of the longitudinal groove 11, the height of the slider 21 is adapted to the height of the transverse groove 12, and the thickness of the slider 21 is adapted to the depth of the transverse groove 12 and the longitudinal groove 11. It should be noted that the length of the slider 21 refers to the distance of the longest side in the horizontal direction, and the depth of the transverse groove 12 and the longitudinal groove 11 refers to the concave distance of the transverse groove 12 and the longitudinal groove 11 along the radial direction of the outer sleeve 1.

[0032] like Figure 3-4As shown, the limit block 3 is slidably set in the limit groove 13 of the outer sleeve 1. In order to prevent the limit block 3 from escaping from the limit groove 13, the limit block 3 and the limit groove 13 slide in a concave-convex manner, that is, the limit block 3 is symmetrically provided with protrusions on both sides (not shown in the figure), and the inner wall of the limit groove 13 is provided with a groove adapted to the protrusion. The two cooperate to limit the limit block 3 in the limit groove 13 and cannot escaping.

[0033] When the inner rod 2 needs to be connected to the outer sleeve 1, the slider 21 of the inner rod 2 is slid through the longitudinal groove 11 to the terminal end of the transverse groove 12, and then the limit block 3 is moved upward so that the top of the limit block 3 is located in the transverse groove 12. At this time, the inner rod 2 is not easy to be separated from the outer sleeve 1, and a flexible pad can be set at the top of the limit groove 13 to relatively fix the limit block 3. At the same time, a limit pad can be bonded to the terminal end of the transverse groove 12, and the thickness of the limit pad gradually increases from the side close to the longitudinal groove 11 to the other side. The side of the slider 21 facing the limit pad is provided with an inclined surface adapted to the limit pad. The cooperation of the limit pad and the inclined surface of the slider 21 can relatively limit the slider 21 at the terminal end of the transverse groove 12, reduce the possibility of movement of the slider 21, and maintain the connection stability between the inner rod 2 and the outer sleeve 1.

[0034] In order to facilitate observation of whether the limit block 3 has moved into place, that is, whether the top end of the limit block 3 has moved into the transverse groove 12, an opening is opened in the limit groove 13 of the outer sleeve 1 (not shown in the figure), the length of the opening is consistent with the limit groove 13, and the width of the opening is smaller than the width of the limit groove 13. A limit protrusion (not shown in the figure) is provided on the limit block 3, and the limit protrusion is located in the opening and contacts with the inner wall of the opening. The position of the limit protrusion in the opening can be used to know the position state of the limit block 3, thereby knowing whether the limit block 3 has moved into place.

[0035] In order to further improve the connection stability between the inner rod 2 and the outer sleeve 1, the outer wall of the stopper 3 is connected to the conical ring 4, which is located at the bottom end of the outer sleeve 1. The outer diameter of the conical ring 4 is adapted to the inner diameter of the outer sleeve 1, and the inner diameter of the conical ring 4 gradually decreases from top to bottom, so that the conical ring 4 is adapted to the gap between the bottom end of the inner rod 2 and the inner wall of the outer sleeve 1. When the slider 21 is located at the terminal end of the transverse groove 12 and the top end of the stopper 3 moves into the transverse groove 12, the top end of the conical ring 4 is plugged in the gap between the bottom end of the inner rod 2 and the inner wall of the outer sleeve 1, further stabilizing the connection between the inner rod 2 and the outer sleeve 1.

[0036] like Figure 3 and Figure 5As shown, a bottom ring 5 can be fixedly connected to the bottom end of the conical ring 4, the outer diameter of the bottom ring 5 is larger than the inner diameter of the outer jacket 1, and the bottom ring 5 is located outside the outer jacket 1. The conical ring 4 can be easily moved through the bottom ring 5, and the outer peripheral surface of the bottom ring 5 can be bent axially to form a bending portion for sleeved on the outer surface of the bottom end of the outer jacket 1, so that the bottom ring 5 can be sleeved on the outer jacket 1, reducing the possibility of the conical ring 4 detaching. The top of the inner rod 2 and the outer peripheral surface of the outer jacket 1 are provided with mounting protrusions or mounting notches for connecting with other objects. For example, the base can be installed on the outer jacket 1, and the base is fixedly set somewhere. The top of the inner rod 2 is connected to a small electronic product, and the small electronic product is fixed on the base through the quick connection between the inner rod 2 and the outer jacket 1.

[0037] In this embodiment, the outer sleeve 1 and the inner rod 2 are quickly connected by the cooperation of the slider 21 with the longitudinal groove 11 and the transverse groove 12. Under the restriction of the limit block 3, the connection between the two is stable, the operation is simple, and quick plugging and unplugging can be achieved. The connection stability of the inner rod 2 in the outer sleeve 1 can be further improved by the tapered ring 4, and it moves synchronously with the limit block 3. The two cooperate to stabilize the connection between the inner rod 2 and the outer sleeve 1.

[0038] Example 2

[0039] This embodiment introduces a plug-in quick-release structure, which is basically the same as the plug-in quick-release structure introduced in Embodiment 1. The difference is that this embodiment uses an observation hole instead of an opening and a limiting protrusion, and an observation hole (not shown in the figure) for viewing the position state of the limiting block 3 is opened radially at the connection between the limiting groove 13 and the transverse groove 12. When the limiting block 3 is viewed in the observation hole, it means that the top end of the limiting block 3 has moved into the transverse groove 12.

[0040] This embodiment has the same beneficial effects as Embodiment 1.

[0041] The technical scope of the present invention is not limited to the contents described above.
