Detailed Description

The overall structure and the main components of the present embodiment are shown in fig. 1 to 10, and include a binding clip 1, an outer disc 2, an inner disc 3, a column 8, a left handle 4 and a right handle 5. The central axes of the outer disc 2 and the inner disc 3 are the same, and the inner disc 3 can rotate relative to the outer disc 2 inside the outer disc 2 under the action of external force. The number of the forceps heads 1 is 3, the forceps heads are distributed at 120 degrees and are uniformly arranged on the circumference of the outer disc 2. The outer disc 2 is provided with a radial slideway 10, the outer end of the binding clip 1 is provided with a slide block 9 matched with the slideway 10, and the slide block 9 can slide in the slideway 10 in the radial direction. 3 locating holes 12 are arranged in the middle of the inner end of the binding clip 1, the locating holes 12 are arranged in the radial direction, a track 7 is obliquely arranged on the inner disc 3, namely the distance from one end of the track 7 to the disc center is shorter than the distance from the other end of the track 7 to the disc center, the upright post 8 can be matched with the track 7, and the upright post 8 can move in the track 7 after passing through the locating holes 12. Furthermore, the upright post 8 is provided with a tightening device which can lock the upright post 8 on the track 7. The upper end of the upright 8 may be provided with a bearing to reduce resistance when the upright 8 moves in interaction with the track 7. When the extension of the binding clip 1 is adjusted, the inner disc 3 rotates along the outer disc 2 through external force, the upright post 8 slides in the track 7 in an inclined way, so that the binding clip 1 is driven to move, and meanwhile, the sliding block 9 of the binding clip 1 radially displaces in the slide way 10. The upright post 8 can be inserted into 3 different positioning holes 12, and the range of the movable radius of the clamp head 1 can be greatly adjusted, so that the sealing ring mounting tool can mount sealing rings with different sizes.

The left and

right grips

4 and 5 are used to facilitate rotation of the outer and

inner discs

2 and 3, which can be fixed and released from the outer and

inner discs

2 and 3, respectively. In this embodiment, left grab handle 4 and right grab handle 5 articulate on the center pin, and the position on outer dish 2 on left grab handle 4 sets up first hasp 61, and the position on inner dish 3 on left grab handle 4 sets up second hasp 62, and the position on outer dish 2 on right grab handle 5 sets up third hasp 63, and the position on inner dish 3 on right grab handle 5 sets up fourth hasp 64, and four hasps can be fixed the grab handle on the disc. When the second lock catch 62 and the third lock catch 63 are fixed, the left grab handle 4 can drive the inner disc 3 to rotate anticlockwise, and the tong head 1 moves outwards along the radial direction under the action of the slide block 9 and the slide way 10; when the first lock catch 61 and the fourth lock catch 64 are fixed, the right grab handle 5 can drive the inner disc 3 to rotate clockwise, and the tong head 1 moves inwards in the radial direction under the action of the slide block 9 and the slide way 10. The left grab handle 4 and the right grab handle 5 can realize four states of fixing the left grab handle and the right grab handle, completely releasing the left grab handle and the right grab handle, driving the inner disc to rotate along the outer disc anticlockwise and driving the inner disc to rotate clockwise by the left grab handle and the right grab handle through different matching of the four lock catches.

A spring 13 is arranged between the left grab handle 4 and the right grab handle 5, and the grab handle automatically resets under the action of the spring 13 after the grab handle is loosened, so that the clamp head 1 is driven to reset. The forceps head 1 is provided with a forceps mouth 11 at one side end of the positioning hole 12, as shown in fig. 11 and 12, the forceps mouth 11 is used for contacting the sealing ring to open or press the sealing ring.

When the clamp is used, the second lock catch 62 and the third lock catch 63 are fixed, the left grab handle 4 can drive the inner disc 3 to rotate anticlockwise, and under the driving action of the upright post 8 and the supporting action of the sliding block 9 and the slide way 10, the clamp head 1 moves outwards along the radial direction, so that the outer seal can be spread and used for installing an external sealing ring of a shaft; the first lock catch 61 and the fourth lock catch 64 are fixed, and the right grab handle can drive the inner disc to rotate clockwise, so that the tong head moves inwards along the radial direction, and the inner sealing ring arranged in the periphery can be reduced in pressure and used for installing the inner sealing ring arranged in the shaft. The spring is arranged between the left grab handle and the right grab handle, and the grab handle automatically resets under the action of the spring after the grab handle is loosened, so that the clamp head is driven to reset, and the operation of personnel is facilitated.

For diversified operation, the inner disc 3 is provided with positioning holes 12 at different positions according to actual needs, and the stand column 8 can change the moving radius of the tong head 1 in different positioning holes 12, i.e. the stand column 8 is arranged in different positioning holes 12, so that the sealing ring mounting tool can mount sealing rings with different sizes.
