Furthermore, in order to support the driving plate 301 and prevent the driving plate 301 from rolling over due to the acting force between the spring 404 and the connecting rod 202, a support member 504 is further fixed between the driving plate 301 and the slot 201, the support member 504 is in the shape of a circular plate 506 rotatably connected to the bottom surface of the slot 201, the circular plate 506 abuts against the bottom surface of the slot 201, the rotating plane of the circular plate 506 is parallel to the bottom surface of the slot 201, a plurality of support rods 505 are further fixed between the circular plate 506 and the driving plate 301, in this embodiment, the number of the support rods 505 is 3, and when the driving plate 301 rotates, the circular plate 506 and the support rods 505 rotate similarly, and the support of the driving plate 301 is also ensured.

The rest of the structure is the same as in example 2.

The operation process is as follows: when an operator installs the connecting rod 202, the operator inserts the connecting rod 202 downwards, the unlocking groove 503 is staggered with the position of the hook plate 500 when the connecting rod is inserted, after the insertion, the annular edge 502 is matched with the hook plate 500, and under the action of the spring 404 at the lower end of the connecting rod 202, the annular edge 502 is matched with the hook plate 500 more tightly, when the connecting rod 202 is pulled out subsequently, the operator reversely screws the connecting rod 202, the connecting rod 202 rotates upwards under the action of the arc-shaped inclined plane 402 and the arc-shaped sliding groove 403, the unlocking groove 503 just corresponds to the position of the hook plate 500, at the moment, the arc-shaped inclined plane 402 is also separated from the arc-shaped sliding groove 403, at the moment, the connecting rod 202 can be pulled out outwards, the structure is simple, the action effect between the inclined planes is utilized, and the effect of more convenient and stable pulling out and connection is realized.

Example 4

Referring to fig. 2, this embodiment differs from the above embodiment in that: the rotating member 104 includes a spiral groove 600 disposed at the rear end of the core rod 102, a spiral rod 601 disposed at the front end of the copper wire 103 and engaged with the spiral groove 600, and an insertion hole 602 disposed on the side wall of the spiral groove 600, and the rear end of the insulating sheath 101 is provided with an opening 603, wherein the opening 603 is communicated with the spiral groove 600.

Specifically, in this embodiment, the rotating member 104 includes a spiral groove 600 disposed at the rear end of the core rod 102, the spiral groove 600 is communicated to the outside of the insulating sleeve 101, then a spiral rod 601 is fixed at the front end of the copper wire 103, the copper wire 103 is wound and then welded to the spiral rod 601, meanwhile, two side walls of the spiral groove 600 are provided with jacks 602 matched with two ends of the spiral rod 601, the jacks 602 are matched with two ends of the spiral rod 601 to be connected, and then the copper wire 103 can rotate, and an opening 603 is formed at the rear end of the insulating sleeve 101, and the opening 603 is communicated with the spiral groove 600, and is communicated to the outside of the insulating sleeve 101, and further the rotation of the copper wire 103 is not hindered.

The rest of the structure is the same as in example 3.

The operation process is as follows: the operator is when the preparation adapter, and the operator sets up the winding of copper line 103 on the swing arm 601, then carries out welded fastening, later the operator inserts the swing arm 601 in the jack 602, and copper line 103 and core bar 102 equipment are accomplished this moment, can take place relative rotation between copper line 103 and the core bar 102, and then realize the adjustable of angle.

It is important to note that the construction and arrangement of the present application as shown in the various exemplary embodiments is illustrative only. Although only a few embodiments have been described in detail in this disclosure, those skilled in the art who review this disclosure will readily appreciate that many modifications are possible (e.g., variations in sizes, dimensions, structures, shapes and proportions of the various elements, values of parameters (e.g., temperatures, pressures, etc.), mounting arrangements, use of materials, colors, orientations, etc.) without materially departing from the novel teachings and advantages of the subject matter recited in this application. For example, elements shown as integrally formed may be constructed of multiple parts or elements, the position of elements may be reversed or otherwise varied, and the nature or number of discrete elements or positions may be altered or varied. Accordingly, all such modifications are intended to be included within the scope of this invention. The order or sequence of any process or method steps may be varied or re-sequenced according to alternative embodiments. In the claims, any means-plus-function clause is intended to cover the structures described herein as performing the recited function and not only structural equivalents but also equivalent structures. Other substitutions, modifications, changes and omissions may be made in the design, operating conditions and arrangement of the exemplary embodiments without departing from the scope of the present inventions. Therefore, the present invention is not limited to a particular embodiment, but extends to various modifications that nevertheless fall within the scope of the appended claims.

Moreover, in an effort to provide a concise description of the exemplary embodiments, all features of an actual implementation may not be described (i.e., those unrelated to the presently contemplated best mode of carrying out the invention, or those unrelated to enabling the invention).

It should be appreciated that in the development of any such actual implementation, as in any engineering or design project, numerous implementation-specific decisions may be made. Such a development effort might be complex and time consuming, but would nevertheless be a routine undertaking of design, fabrication, and manufacture for those of ordinary skill having the benefit of this disclosure, without undue experimentation.

It should be noted that the above-mentioned embodiments are only for illustrating the technical solutions of the present invention and not for limiting, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions may be made on the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, which should be covered by the claims of the present invention.
