[0025] Embodiment 1: Please refer to Figures 1-4, an embodiment provided by the present utility model: a sealing ring installation tool, including a handheld housing 1, a limiting device 2 installed on the handheld housing 1, a rotating shaft 3, and a supporting device 5,

[0026] The rotating shaft 3 passes through the middle of the handheld housing 1, and a handwheel is provided at the top. The rotating shaft 3 passes through the middle of the handheld housing 1 and is the rotation core of the entire device. By rotating the handwheel, the rotating shaft 3 is driven to rotate, so that the arc-shaped plate 504 and related components can rotate and adjust their positions, thereby realizing the installation and positioning of the sealing ring, increasing or decreasing the distance between the positioning rods 506, thereby expanding or squeezing the sealing ring. At the same time, an arc-shaped handheld groove is provided on the handwheel, and the fingers are accommodated in the handheld groove to facilitate driving the device. A limiting groove 4 is provided on the outer circumference of the rotating shaft 3 between the handwheel and the handheld housing 1. The limiting groove 4 is provided on the outer circumference of the rotating shaft 3 and is used to cooperate with the limiting device 2 to realize the restriction of the rotation of the rotating shaft 3. The bottom end of the rotating shaft 3 is connected to an arc-shaped plate 504. The arc-shaped plate 504 is connected to the bottom end of the rotating shaft 3. By rotating, the arc-shaped rod 505 is driven to rotate and at the same time the slider 503 is driven to slide on the guide rail 502, realizing the conversion of the rotational motion, transmitting the rotational motion of the rotating shaft 3 to the slider 503 and the positioning rod 506, and supporting the stretching and installation of the sealing ring. Four symmetric corners are provided on the arc-shaped plate 504. A boss 501 is provided between the arc-shaped plate 504 and the handheld housing 1. The boss 501 provides a fixed foundation for the guide rail 502 and is sleeved on the rotating shaft 3. A plurality of guide rails 502 are evenly distributed at an angle on the outer circumference of the boss 501. The other end of the guide rail 502 is connected to the inner wall of the handheld housing 1. Sliders 503 are respectively slidably fitted on the guide rails 502. The sliders 503 slide on the guide rails 502 and are hinged to the arc-shaped rods 505. When the arc-shaped plate 504 rotates, the arc-shaped rods 505 are driven to rotate, and at the same time the sliders 503 are driven to slide, for adjusting the position of the positioning rod 506, realizing the motion adjustment, and cooperating with the arc-shaped rods 505 and the positioning rods 506 to complete the expansion and installation of the sealing ring. Arc-shaped rods 505 are respectively hinged on the sliders 503. The other ends of the arc-shaped rods 505 are respectively hinged to the four corners of the arc-shaped plate 504. Positioning rods 506 are respectively fixedly connected to the bottom ends of the sliders 503. A sealing ring is sleeved on the positioning rods 506,

[0027] The positioning rod 506 is provided in a conical shape. The positioning rod 506 is obliquely connected to the slider 503, and the top end extends towards the center of the rotating shaft 3. The conical design enables the positioning rod 506 to expand the sealing ring during the movement of the slider 503. The top end of the conical end reduces the distance between the top ends of the positioning rods 506, which is suitable for expanding sealing rings of different sizes and ensures the installation accuracy. At the same time, the oblique connection of the positioning rod 506 enables the sealing ring to smoothly slide into the required position. Bearing seats are respectively provided at the contact ends of the rotating shaft 3 with the handheld housing 1 and the boss 501, for supporting the rotating shaft 3 and reducing friction, providing smooth rotation support, reducing wear and friction, and extending the service life of the device.

[0028] When it is necessary to expand the installation of the sealing ring, the operation can be carried out by sleeving the sealing ring on the obliquely arranged positioning rod 506. Rotate the handwheel, which drives the rotating shaft 3 to rotate, and at the same time drives the arc plate 504 to rotate. The arc plate 504 then drives the arc rod 505 to rotate, thereby enabling the slider 503 to slide on the guide rail 502, so as to increase the distance between the positioning rods 506. After stretching and expanding the sealing ring, then, sleeve the positioning rod 506 at the position where it needs to be installed, and rotate the handwheel again to reduce the distance between the positioning rods 506, so that the sealing ring slides to the position where it needs to be installed through the inclined slope. This method is applicable to the installation of sealing rings of different sizes.

[0029] For the installation of the sealing ring in the oil cylinder, first increase the distance between the positioning rods 506 of the device, make the positioning rod 506 contact the outer side of the sealing ring, and rotate the rotating shaft 3 to make the positioning rod 506 extrude the sealing ring until the sealing ring can extend into the oil cylinder. After the positioning rod 506 extends into the oil cylinder, install the sealing ring in the oil cylinder. This method can meet the installation requirements of the sealing ring in different situations.

[0030] Embodiment 2: Please refer to Figure 1 、 5 On the basis of Embodiment 1, it also has the following structure:

[0031] The limiting device 2 includes a first clamping plate 201, a second clamping plate 202, and a spring 203. The first clamping plate 201 and the second clamping plate 202 are symmetrical and respectively hinged to the handheld shell 1, and their top ends are in conflict with the inner wall of the limiting groove 4. The two clamping plates are symmetrically arranged and hinged to the handheld shell 1, and are used to adjust the opening and closing of the limiting device 2 and maintain contact with the inner wall of the limiting groove 4 on the rotating shaft 3. Their tapered ends are engaged with the inner wall of the limiting groove 4 to ensure stable positioning. The other end of the first clamping plate 201 and the second clamping plate 202 are connected by a spring 203, and the spring 203 provides a restoring force so that the two clamping plates can automatically return to the initial position when not subjected to external force, thereby ensuring the stability and reliability of the device. The first clamping plate 201 and the second clamping plate 202 are extended toward the outer circumference of the handheld shell 1 at one end away from the rotating shaft 3, and the extended portion does not exceed the handheld shell 1, so as to adjust the opening and closing of the limiting device 2 when the handheld device is held. The extended portion of the clamping plate does not exceed the handheld shell 1, thereby ensuring that the device is held in the hand The first clamping plate 201 and the second clamping plate 202 are in contact with the limiting groove 4 at the same time, and the contact ends are conical, and the conical ends are engaged with the inner wall of the limiting groove 4. The conical design ensures that the two clamping plates are accurately positioned in the limiting groove 4, reducing displacement and vibration. In the initial position, the conical ends of the first clamping plate 201 and the second clamping plate 202 are in contact with the inner wall of the limiting groove 4 to limit the position of the rotating shaft 3. When rotation is required, the first clamping plate 201 and the second clamping plate 202 are pressed by fingers to adjust the position. At the other end of the two clamping plates 202, the tapered ends of the first clamping plate 201 and the second clamping plate 202 are away from the limiting groove 4, unlocking the limit of the rotating shaft 3. After the sealing ring is expanded or squeezed, the fingers are released, and the first clamping plate 201 and the second clamping plate 202 are reset by the force of the spring 203, and the tapered ends are re-engaged with the inner wall of the limiting groove 4 to limit the position of the device. It is suitable for adjusting the installation position after the sealing ring expands, and there is no need for manual pressing or fixing the rotation position.
