Therefore, the invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0030] Example 1

[0031] Reference Figure 5 , Figure 6 , Figure 8 and Figure 9 This is the first embodiment of the present invention, which provides a wire retaining ring installation tool for holes, which enables the wire retaining ring 700 to be installed into the metal ring 800 more efficiently and reliably.

[0032] A wire retaining ring installation tool for holes includes a bottom cover 100 and a sleeve 900. The bottom cover 100 has a through hole at its center. At least three mounting grooves 102 are arranged on the upward-facing end of the bottom cover 100 outside the through hole. In this embodiment, four mounting grooves 102 are arranged on the upward-facing end of the bottom cover 100. A top rod 400 is movably connected to the bottom cover 100 via the mounting grooves 102, allowing it to swing inwards towards the center of the bottom cover 100 or outwards away from the center of the bottom cover 100. The lower part of the rod 400 extends downward through the through hole. The outer periphery of the lower end of the top rod 400 has an insertion groove 401a that can be inserted into the inner edge of the retaining ring. The top cover 200 is fixedly connected to the upper side of the bottom cover 100. The bottom cover 100 is fixedly connected to the top cover 200 using several fastening bolts 1000. The upper end of the top rod 400 is restricted between the lower side of the top cover 200 and the bottom cover 100. The inner diameter of the sleeve 900 gradually decreases from top to bottom. The inner periphery of the lower end of the sleeve 900 has a positioning groove 901.

[0033] Specifically, an elastic element 300 is connected to the bottom cover 100 at the mounting slot 102. The upper end of the elastic element 300 is connected to the top rod 400. A connecting slot is opened at the upward-facing end of the bottom cover 100 on the inner side of the mounting slot 102. A cylindrical pin 500 is placed on the bottom cover 100 at the connecting slot. The top rod 400 includes a horizontal part 403. A bent part 402 is fixed to the inner side of the horizontal part 403. A vertical part 402 is fixed to the lower end of the bent part 402. 01. The lower edge of the bent part 402 is just attached to the upper side of the cylindrical pin 500 and can swing around the cylindrical pin 500. In the initial state, that is, when there is no external force, the outer side of the vertical part 401 is attached to the inner edge of the bottom cover 100 and is in a vertical state. The lower side of the top cover 200 is fixed with a limiting boss 201. When the top rod 400 swings inward around the cylindrical pin 500, the inner sides of the bent part 402 and the vertical part 401 can be attached to the outer edge of the limiting boss 201.

[0034] In use, the sleeve 900 is inserted into the upper side of the metal ring 800 via the positioning groove 901. The wire retaining ring 700 is placed on the upper inner edge of the sleeve 900 to make it horizontal. The bottom cover 100 is aligned with the sleeve 900, and the vertical part 401 is vertically inserted into the sleeve 900. The vertical part 401 is just aligned with the upper end of the wire retaining ring 700 along the inner edge of the steel ring via the insertion groove 401a. The top cover 200 is pushed down forcefully, and several push rods 400 simultaneously push the wire retaining ring 700 downward. The wire retaining ring 700 is supported by the inner wall of the sleeve 900. The squeezing force contracts inward, and after a click, the limit position is reached. The inner side of the vertical part 401 fits against the outer side of the limiting boss 201, and the wire retaining ring 700 is successfully installed into the annular limiting groove of the metal ring 800 part. The top cover 200 is moved upward, and the top rod 400 is reset under the action of the elastic element 300, so that the vertical part 401 is in a vertical state. No adjustment is needed, and it can continue to be used to prepare for the installation of the next wire retaining ring 700. Using this invention, the wire retaining ring 700 can be inserted into the limiting groove of the metal ring 800 efficiently and reliably.

[0035] Example 2

[0036] Reference Figure 5 This embodiment provides a wire retaining ring installation tool for holes, which differs from Embodiment 1 in that it can further improve the stability of installing the retaining ring.

[0037] Specifically, an annular positioning sleeve 101 is fixed on the lower side of the bottom cover 100, and the positioning sleeve 101 can slide downward along the outer periphery of the sleeve 900.

[0038] Before pushing the top cover 200 downward, first align the positioning sleeve 101 with the outside of the sleeve 900. The positioning sleeve 101 slides downward along the outer edge of the sleeve 900 and will not move in the circumferential direction, thus improving the stability of the vertical part 401 when it is inserted into the retaining ring.

[0039] Example 3

[0040] Reference Figures 1-4 and Figure 7 This embodiment provides a wire retaining ring installation tool for holes, which differs from Embodiment 1 or 2 in that it can further facilitate the connection of the bottom cover 100, the elastic element 300 and the top rod 400.

[0041] Specifically, the bottom cover 100 has a number of threaded countersunk holes 104 corresponding to the elastic element 300 at its downward end. The bottom cover 100 above the threaded countersunk holes 104 has a connecting hole 103. The elastic element 300 includes a threaded connection part 302 that is threadedly connected to the bottom cover 100 through the threaded countersunk holes 104. A handle 301 is fixed to the lower side of the threaded connection part 302. A guide part 305 that passes through the threaded countersunk holes 104 and is inserted into the connecting hole 103 is fixed to the upper side of the threaded connection part 302. A return spring 303 is fixed to the upper side of the guide part 305. A mounting part 304 is fixed to the upper end of the return spring 303. The top cover 200 has a number of mounting countersunk holes 105 corresponding to the mounting parts 304. The mounting parts 304 can pass through the threaded countersunk holes 104 and the connecting hole 103 from bottom to top and be inserted into the mounting countersunk holes 105. A fixing hole 403a is opened on the horizontal part 403 to facilitate connection with the mounting part 304.

[0042] When installing the elastic element 300, first pass the guide part 305 and the return spring 303 through the threaded countersunk hole 104 and the connecting hole 103 from bottom to top. Hold the handle 301 and screw the threaded connecting part 302 into the threaded countersunk hole 104 until the upper side of the threaded connecting part 302 abuts against the bottom cover 100 on the upper side of the threaded countersunk hole 104. Align the mounting countersunk hole 105 on the horizontal part 403 with the mounting part 304. The horizontal part 403 is sleeved on the mounting part 304 through the mounting countersunk hole 105. The upper part of the return spring 303 is also in the mounting countersunk hole 105. Use the fixing bolt 600 to screw into the fixing hole 403a and the mounting part 304 to fix the mounting part 304 to the horizontal part 403, thus realizing the connection between the elastic element 300, the bottom cover 100, and the top rod 400. The installation is convenient and facilitates the replacement of the elastic element 300 when the elastic element 300 fails later.

[0043] Example 4

[0044] Reference Figure 10 This embodiment provides a wire retaining ring installation tool for holes, which differs from Embodiment 3 in that it facilitates the connection between the elastic element and the base.

[0045] Specifically, the threaded connection part 302 has a non-circular countersunk hole 302a at the downward-facing end. In this embodiment, the countersunk hole 302 is hexagonal.

[0046] When installing the elastic element 302, use a tool to insert into the countersunk hole 302a and rotate the tool to gradually screw the threaded connection part 302 into the bottom cover 100.
