[0042] The inner surface of the outer cylinder is often axially limited by a retaining ring, which is specifically an open ring structure. The inner surface of the outer cylinder is provided with a receiving groove. Currently, the retaining ring is often directly pushed from the end face of the outer cylinder into the receiving groove by external force. The retaining ring can easily cause damage to the inner hole of the outer cylinder, affecting product quality.

[0043] The built-in retaining ring installation tool provided by the utility model firstly comprises a main body 1, a connecting member and a limiting member 3, wherein a receiving groove is provided at the bottom of the main body 1, and the receiving groove is used to accommodate the retaining ring 6 after the diameter is reduced. After that, the main body 1 is extended into the preset position in the outer cylinder 4, and the retaining ring 6 will not directly contact the inner surface of the outer cylinder 4, so as to avoid the situation of pulling the inner surface of the outer cylinder 4. The connecting member is fixedly connected to the main body 1, and a limiting member 3 is provided at one end of the connecting member away from the main body 1, and the limiting member 3 is used to abut against the end surface of the outer cylinder 4, so that the main body 1 is placed at the preset position in the outer cylinder 4, so as to facilitate the installation of the retaining ring 6. Secondly, a pusher groove 5 is also provided, and the pusher groove 5 is provided at one end of the main body 1 away from the receiving groove, and the pusher groove 5 is connected with the receiving groove, and the retaining ring 6 is pushed by the pusher groove 5, and the retaining ring 6 falls off and is released from the receiving groove, and the retaining ring 6 is directly installed in the retaining ring receiving groove on the inner surface of the outer cylinder 4. It can be seen that, compared with the prior art, the built-in retaining ring installation tool in the embodiment of the utility model can more conveniently install the retaining ring without damaging the inner wall of the outer cylinder 4.

[0044] It should be noted that the retaining ring in the present application is specifically an open ring structure. The size of the receiving groove in the main body 1 is smaller than the diameter of the retaining ring. The retaining ring is first reduced in diameter and placed in the receiving groove, and then the main body 1 is placed in the outer cylinder 4, and the retaining ring is released and installed in the retaining ring installation groove.

[0045] Furthermore, for the installation of the retaining ring, it can be forcibly placed in the receiving groove by external force, or the retaining ring can be first reduced in diameter by external force and released after being placed in the receiving groove. The main body 1 can also be preheated by thermal expansion and contraction to increase the diameter of the receiving groove, and then the retaining ring can be placed inside the receiving groove.

[0046] Furthermore, as one embodiment, the preset position of the body 1 in the outer cylinder 4 is specifically: when the retaining ring is released from the receiving groove, the retaining ring can be placed in the retaining ring installation groove. The preset position is preferably: the bottom surface of the body 1 is aligned with the upper surface of the retaining ring installation groove.

[0047] Furthermore, the retaining ring can be directly inserted into the retaining ring installation groove when released. If the retaining ring is not inserted into the retaining ring installation groove when released, the retaining ring can also be pushed toward the direction of the retaining ring installation groove by external force, and finally the retaining ring is inserted into the retaining ring installation groove. Compared with the prior art, the retaining ring has a shorter moving stroke and has less impact on the inner surface of the outer cylinder 4.

[0048] Furthermore, the pusher groove 5 is used to communicate with the receiving groove, and the external force can act on the reduced diameter retaining ring through the pusher groove 5, pushing the retaining ring out of the receiving groove and releasing it.
