DETAILED DESCRIPTION

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1: A connecting rod 16 is installed between the first mounting bracket 3 and the second mounting bracket 15. Multiple limiting grooves 5 are equally spaced on the outer periphery of the first mounting bracket 3 and the second mounting bracket 15. A base plate 7 is movably installed inside the limiting groove 5. A limiting plate 11 is installed on each side of the top of the base plate 7. A second sliding groove 10 is opened inside each of the two limiting plates 11. A cavity 14 is opened inside each end of the plum blossom contact body 1. Two supporting sliding rods 13 are installed inside the cavity 14. A sliding plate 12 is movably fitted on the outer side of each end of the two supporting sliding rods 13. A limiting sliding rod 6 is installed on one side of the sliding plate 12. The limiting sliding rod 6 cooperates with the second sliding groove 10. A supporting spring 4 is installed on the outer side of the supporting sliding rod 13.

[0020] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, since multiple limiting grooves 5 are equally spaced on the outer periphery of the first mounting bracket 3 and the second mounting bracket 15, and a base plate 7 is movably installed inside the limiting groove 5, when the plum blossom contact body 1 is installed into the limiting groove 5, since a second sliding groove 10 is provided on each side of the base plate 7, and a limiting sliding rod 6 is movably installed on each side of the plum blossom contact body 1, with one end of the limiting sliding rod 6 extending out of the cavity 14, the plum blossom contact body 1 can be installed into the base plate 7, thereby inserting the two limiting sliding rods 6 into the two second sliding grooves 10 respectively, ensuring that the plum blossom contact body 1 can move along the groove. The position moves along the opening direction of the second slide groove 10. Since the skeleton spring 2 is installed on the outside of the plum blossom contact body 1, the skeleton spring 2 can simultaneously restrict multiple plum blossom contact bodies 1 inside the limiting groove 5. At the same time, when installing the plum blossom contact, one end of multiple plum blossom contact bodies 1 will be expanded outward. During the expansion of the plum blossom contact body 1, the plum blossom contact body 1 will slide along the opening direction of the second slide groove 10 through the limiting slide rods 6 installed on both sides, thereby avoiding the plum blossom contact body 1 from getting stuck or falling off during the expansion process, thereby improving the use effect of the plum blossom contact.

[0021] In the embodiment 2, two third sliding grooves 17 are respectively arranged on the two sides of the top of the main body 1 of the star-shaped contact, and the third sliding grooves 17 are communicated with the inside of the cavity 14; the top end of the sliding plate 12 extends out of the inside of the cavity 14 through the third sliding grooves 17; one skeleton spring 2 is respectively arranged on the outside of the two ends of the main body 1 of the star-shaped contact; one first sliding groove 9 is respectively arranged on the two sides of the inside of the limiting groove 5; one limiting sliding block 8 is respectively arranged on the bottom end of the two sides of the bottom plate 7; one end of the two limiting sliding blocks 8 extends into the inside of the first sliding groove 9; the limiting sliding block 8 is slidingly arranged in the inside of the first sliding groove 9; and the second sliding groove 10 is in an arc shape.

[0022] Specifically, as shown in Figure 1 , Figure 2 , Figure 3 and Figure 4 , since the top end of the sliding plate 12 extends out of the inside of the cavity 14 through the third sliding grooves 17, the relative sliding of the sliding plate 12 in the cavity 14 along the installation direction of the supporting sliding rod 13 can be controlled by controlling the top end of the two sliding plates 12, so as to control the limiting sliding rod 6 to enter or extend out of the inside of the cavity 14; since the limiting sliding blocks 8 arranged on the bottom ends of the two sides of the bottom plate 7 extend into the inside of the first sliding groove 9, and the limiting sliding blocks 8 are slidingly arranged in the inside of the first sliding groove 9, when the one end of the main body 1 of the star-shaped contact is expanded, the bottom plate 7 will move up and down in the limiting groove 5 along the direction in which the first sliding groove 9 is arranged, so as to further improve the expansion range of the main body 1 of the star-shaped contact, and facilitate the installation of the star-shaped contact; since the second sliding groove 10 is in an arc shape, the expansion of the one end of the main body 1 of the star-shaped contact is more smooth.

[0023] Working principle: During use, when the plum blossom contact body 1 is installed into the limiting groove 5, since a second sliding groove 10 is opened on each side of the base plate 7, and a limiting sliding rod 6 is movably installed on each side of the plum blossom contact body 1, with one end of the limiting sliding rod 6 extending out of the cavity 14, the plum blossom contact body 1 can be installed into the base plate 7. During installation, by controlling the top of the two sliding plates 12, the sliding plates 12 can be controlled to slide relative to each other in the cavity 14 along the installation direction of the supporting sliding rod 13, thereby retracting one end of each limiting sliding rod 6 into the cavity 14. Then, the plum blossom contact body 1 is inserted into the base plate 7, and then the sliding plates 12 are released so that the two limiting sliding rods 6 are inserted into the two second sliding grooves 10 respectively, ensuring that the plum blossom contact body 1 can move along the opening direction of the second sliding groove 10. After multiple plum blossom contact bodies 1 are installed into the base plate 7, the multiple plum blossom contact bodies 1 can be moved by the skeleton spring 2. The contact body 1 is simultaneously confined within the limiting groove 5. During the installation of the plum blossom contact, one end of each plum blossom contact body 1 expands outwards. During this expansion, the plum blossom contact body 1 slides along the opening direction of the second slide groove 10 via the limiting slide rods 6 installed on both sides, thus preventing the plum blossom contact body 1 from getting stuck or falling off during expansion, thereby improving the performance of the plum blossom contact. Since the limiting sliders 8 installed at the bottom of both sides of the base plate 7 extend into the interior of the first slide groove 9, and the limiting sliders 8 are slidably installed inside the first slide groove 9, when one end of the plum blossom contact body 1 is expanded, the base plate 7 will move up and down within the limiting groove 5 along the opening direction of the first slide groove 9, further increasing the expansion range of the plum blossom contact body 1 and facilitating the installation of the plum blossom contact. Because the second slide groove 10 is arc-shaped, it allows one end of the plum blossom contact body 1 to expand more smoothly during the expansion process.

[0024] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
