In addition, if the terms "first", "second", "third" appear, they are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0024] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] Figure 1 This is a structural schematic diagram of a clamp spring assembly tooling of the utility model. Figure 2 This is a schematic diagram of the structure of a connecting rod of a clamp spring assembly tooling of the utility model. Figure 3 This is a cross-sectional view of a clamp spring assembly tool of the utility model. Figure 4 2 is a cross-sectional view of a ring and a push rod of a retaining spring assembly tool of the utility model, as shown in FIG. Figure 1-4 As shown, a preferred embodiment of a retaining ring 5 assembly tool is shown, which is used to assemble the retaining ring 5 into the retaining groove 12 on the connecting rod 1 to limit the bearing 4 to the bearing groove 11 on the connecting rod 1, including a snare 2 and a push rod 3. The snare 2 is coaxially provided with a hole body 22, and the hole body 22 includes a positioning section 222 and a pushing section 221 that are connected to each other. The diameter of the positioning section 222 decreases along its axial direction toward the pushing section 221. The diameter of the push rod 3 matches the diameter of the pushing section 221 and can slide axially in the pushing section 221. The maximum inner diameter of the retaining ring 5 is smaller than the diameter of the push rod 3. One end of the push rod 3 is coaxially provided with a positioning column 31 whose diameter matches the inner diameter of the bearing 4.

[0026] When in use in this embodiment, the clamping spring 5 is installed into the hole body 22 from the positioning section 222, and then the end of the push rod 3 with the positioning column 31 is inserted into the hole body 22 from the positioning section 222 and pushed forward. At the same time, the connecting surface of the push rod 3 and the positioning column 31 pushes the clamping spring 5 to move synchronously, and the clamping spring 5 gradually shrinks as the diameter of the positioning section 222 gradually decreases, until the clamping spring 5 is pushed into the pushing section 221;

[0027] Then, the push rod 3 is slowly pushed to push the retaining spring 5 to the opening of the pushing section 221 away from the positioning section 222;

[0028] Install the bearing 4 into the bearing groove 11, and extend the positioning column 31 coaxially into the bearing 4, then press the connecting rod 1 against the ring 2, and continue to push the push rod 3 again, push the retaining spring 5 from the pushing section 221 to the retaining groove 12, and the retaining spring 5 automatically restores its deformation and is locked into the retaining groove 12 to limit the bearing 4.

[0029] In this embodiment, when the clamping spring 5 is assembled, not only the assembly difficulty is reduced, the assembly success rate and work efficiency are improved, but also the damage to the clamping spring 5 during assembly is reduced.

[0030] Furthermore, as a preferred embodiment, the outside of the trap 2 away from the pushing section 221 has a first seat 21 .

[0031] Furthermore, as a preferred embodiment, a second seat 32 is provided outside the end of the push rod 3 away from the positioning column 31 .

[0032] Furthermore, as a preferred embodiment, the inner diameter of the bearing groove 11 matches the diameter of the push rod 3 .

[0033] Furthermore, as a preferred embodiment, the clamping groove 12 is coaxially arranged on the inner wall of the groove of the bearing groove 11 .

[0034] Furthermore, as a preferred embodiment, a bearing sleeve 6 is provided between the bearing 4 and the bearing groove 11 .

[0035] Furthermore, as a preferred embodiment, the largest opening of the positioning section 222 is rounded.

[0036] Furthermore, as a preferred embodiment, the snare 2 is a cylindrical structure.

[0037] The above description is only a preferred embodiment of the present invention, and does not limit the implementation mode and protection scope of the present invention. For those skilled in the art, it should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
