The structure and connection relationship of the rest parts are the same as those described in any of the foregoing embodiments, and are not described herein again to avoid the tedious text.

On the basis of the above embodiments, the present invention continues to describe the technical features and functions of the technical features in the present invention in detail to help those skilled in the art fully understand the technical solutions of the present invention and reproduce them.

As shown in fig. 1 to 3, the internal screw 9 of the present invention includes a rod body, wherein both ends of the rod body are respectively processed with an internal screw top end 1 and an expansion portion 5, the internal screw top end 1 is a tip end with an inner end capable of being drilled into an object, a threaded portion 7 formed by external threads is processed on the rod body near the internal screw top end 1, the threaded portion 7 can be in threaded fit with a ring body of the external support 2, and the expansion portion 5 is driven to move relative to the external support 2 by screwing in.

In the utility model, a plurality of outer supporting rod bodies 3 distributed around the central axis of the ring body are arranged on one side of the ring body of the outer supporting body 2, the outer supporting rod bodies 3 extend to one side far away from the ring body, rod body clamping ends 4 are processed at the end parts of the outer supporting rod bodies 3 far away from the ring body, and the rod body clamping ends 4 are provided with tips capable of penetrating into the connected object.

In an initial state, the expansion part 5 is positioned outside the rod body clamping end 4, the expansion part 5 approaches to the rod body clamping end 4 and the inclined surface is gradually contacted with the rod body clamping end 4 in the screwing process of the inner screw 9 along with the screw thread part 7, and the rod body clamping end 4 can be outwards supported by the expansion part 5 in the contact process so as to be contacted with a reserved hole wall on a plate body. Because body of rod joint end 4 has the pointed end that can penetrate the inside of being connected object, consequently expand the back that the supporting part 5 outwards propped up, when outer supporting body 2 has the trend that breaks away from outside the preformed hole, can be spacing by body of rod joint end 4, and along with the increase that breaks away from the trend, its spacing effect is better. Of course, the tendency to disengage as described in the present invention should be defined to be within the connection strength of the connector and should not exceed the set connection strength of the connector when in use.

In the utility model, in order to realize more stable connection between the expansion part 5 and the outer support rod body 3, the inner clamping teeth 8 can be processed on the inner surface of the outer support rod body 3, and the inner clamping teeth 8 can be contacted with the expansion part 5 to realize clamping connection between the two. Specifically, the enlarged support portion 5 of the present invention has a boss structure having a top surface diameter equal to the outer diameter of the inner screw 9 and a bottom surface diameter larger than the outer diameter of the outer screw 9. The inner latch 8 includes a latching surface parallel to the bottom surface of the expansion portion 5 and an inclined surface contacting the end surface. When the expansion part 5 is in contact with the outer support rod body 3 along with the screwing of the inner screw 9, the clamping surface of the inner clamping tooth 8 does not hinder the tendency of the expansion part 5 to move towards the ring body direction of the outer support body 2, and the inclined surface of the inner clamping tooth 8 can also assist the tendency of the expansion part 5 to move towards the ring body direction of the outer support body 2. However, when the screwed-in expansion part 5 moves in a direction away from the ring body of the outer support body 2, the clamping surface of the inner clamping tooth 8 contacts and fits with the bottom surface of the expansion part 5, so that the expansion part 5 can be effectively prevented from being separated from the outer support body 2, and the connection effect between the expansion part 5 and the outer support body 2 is further improved.

In the utility model, an end connecting piece 10 can be further processed on the bottom surface of the expansion part 5, the end connecting piece 10 and the inner screw 9 are coaxially arranged, a threaded hole is processed at the central axis of the end connecting piece 10, and the end connecting piece 10 can be conveniently driven by a tool, so that the inner screw 9 is screwed into the outer support body 2 through the threaded part 7. Of course, without the end connector 10, a threaded hole may be directly formed on the bottom surface of the expansion portion 5 and threadedly connected to the outer screw 6 through the threaded hole, and the rotation of the inner screw 9 may be driven by the screwing of the outer screw 6, so that the threaded portion 7 may be screwed into the ring body of the outer support 2 by the rotation of the inner screw 9.

When the utility model is used, a mounting hole for placing the outer support body 2 is required to be reserved on one of the objects, and the rod body clamping end 4 on the outer support body 2 is required to be positioned in the mounting hole. After the outer support body 2 is placed into the mounting hole, the rod body clamping end 4 can be contacted with the inner wall of the mounting hole through the screwing in of the inner screw rod 9, and the tip end of the rod body clamping end 4 can be inserted into the inner wall of the mounting hole when the outer support body 2 is separated from the mounting hole. The other object to be connected can be connected with the threaded hole of the end of the inner screw 9 (also the end of the expanded portion 5) through the outer screw 6, and can also be connected with the threaded hole of the end of the inner screw 9 through the other connecting piece with a threaded end.

Finally, although the present description refers to embodiments, not every embodiment contains only a single technical solution, and such description of the present description is for clarity reasons only, and those skilled in the art should make the description as a whole, and the technical solutions in the embodiments can be appropriately combined to form other embodiments that can be understood by those skilled in the art.
