Rhinestone connector

Abstract

The utility model discloses a rhinestone connector which comprises a body part, a connector body comprises a mandrel and a connector, and the connector and the mandrel are of an integrated structure. In conclusion, due to the fact that the connecting piece and the core shaft are of the integrated structure, the phenomenon that in the prior art, due to insufficient concentricity, equipment shakes in the using process can be effectively avoided, and meanwhile the machining cost can be reduced in the machining process. In order to avoid the phenomenon that the grip rotates anticlockwise when the connector is used, the outer portion of the body part is connected with the arranged grip, and the grip is further provided with a limiting groove. After a limiting piece arranged on the body part abuts against the inner side of the limiting groove, the grip is prevented from rotating on the body part in the anticlockwise direction. Particularly, the grip can be prevented from sliding up and down along the central axis of the core shaft through mutual matching of the limiting groove and the limiting piece.

[0007] As a preferred technical solution of the present invention: the upper end surface of the highest point is a plane, and both sides of the highest point extend toward the first low point and the second low point respectively.

[0008] As a preferred technical solution of the present invention: after the highest point extends to both sides, the first lowest point and the highest point, as well as the second lowest point and the highest point, are connected by inclined surfaces.

[0009] As a preferred technical solution of the present invention: a connecting hole is further provided on the main body portion, and the connecting hole is threadedly connected to the limiting member.

[0010] By adopting the above technical solution, the beneficial effect of the utility model is that since the connecting piece and the core shaft are an integrated structure, the problem of the device shaking during use due to insufficient concentricity in the prior art can be effectively solved.

[0016] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and are not to be construed as limitations on the present invention. In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "upper surface", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be construed as a limitation on the present invention.

[0017] See also Figure 1-4 The present invention provides an embodiment of a water drill connector, comprising a body portion 1, wherein the body portion 1 includes a core shaft 11 and a connector 12, wherein the connector 12 and the core shaft 11 are integrally formed. In summary, since the connector 12 and the core shaft 11 are integrally formed, the problem of the prior art causing the device to vibrate during use due to insufficient concentricity can be effectively solved, while also reducing processing costs.

[0018] To prevent the handle 2 from rotating counterclockwise during use, the exterior of the body 1 is connected to the handle 2, and the handle 2 is also provided with a retaining groove 20. A retaining member 3 provided on the body 1 abuts against the interior of the retaining groove 20, thereby preventing the handle 2 from rotating counterclockwise on the body 1. In particular, the retaining groove 20 and retaining member 3 cooperate to prevent the handle 2 from sliding up and down along the central axis of the core shaft 11.

[0019] Furthermore, since the limiting groove 20 has a first low point 21 and a second low point 23, and a highest point 22 is provided between the first low point 21 and the second low point 23, when the limiting member 3 enters the second low point 23, the handle 2 can be prevented from rotating counterclockwise. At the same time, when the limiting member 3 moves from the second low point 23 to the highest point 22, the ball 4 can be urged to drive the driving rod 13 downward, that is, the ball 4 moves up and down in the first notch 14 on the core shaft 11, and the downward movement of the driving rod 13 is then used to cause the expansion connector 5 at the upper end of the driving rod 13 to move toward the inside of the core shaft 11, so as to facilitate the loosening of the connector and the drill bit.

[0020] When the limiting member 3 moves from the highest point 22 to the first lowest point 21, that is, the ball 4 moves from the first groove 14 to the second groove 15, when the limiting member 3 enters the first lowest point 21, the ball completely enters the second groove 15. At this time, the handle 2 is pushed downward, and the ball 4 moves downward in the second groove 15. The driving rod 13 can be used to drive the expansion connector 5 to completely shrink into the core shaft 11. At this time, the connector can be separated from the drill bit of the water drill, making it easy to remove the drill bit of the water drill from the connector.

[0021] To increase the dwell time of the ball 4 at the highest point 23, the upper end surface of the highest point 22 is flat, with both sides of the highest point 22 extending toward the first and second lowest points 21, 23, respectively. Thus, the stopper 3 can move a certain distance at the highest point 3. During this travel, the stopper 3 prevents the ball 4 from moving upward within the first groove 14, thereby preventing the ball 4 from abutting against the upper surface of the first groove 14 and, in turn, preventing the expansion connector 5 from expanding outward again and causing the drill bit of the diamond to separate from the connector. Furthermore, the stopper 3 can continuously and stably force the ball 4 to abut against the upper surface inside the first groove 14, ensuring a sustained separation effect.

[0022] Furthermore, after the highest point 22 extends to both sides, the first lowest point 21 and the highest point 22, as well as the second lowest point 23 and the highest point 22 are connected by inclined surfaces. Therefore, the limit member 3 moves smoothly from the second lowest point 23 to the highest point 22, and the handle 2 has an obvious downward movement tendency, so as to drive the ball 4 to move smoothly and steadily from the first groove 14 to the second groove 15.

[0023] In addition, a connecting hole 10 is provided on the main body portion 1, and the connecting hole 10 is threadedly connected to the limiting member 3, thereby making the installation and replacement of the limiting member 3 simple and convenient.

[0024] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It is apparent to those skilled in the art that various changes, modifications, substitutions, and variations to these embodiments may be made without departing from the principles and spirit of the present invention, and these changes and modifications still fall within the scope of protection of the present invention.
