The middle part of the mother pressure plate 3 is a rectangular module structure, one side of the mother pressure plate 3 is a trapezoidal structure, and the front end of the trapezoidal structure on the other side of the mother pressure plate 3 is provided with an arc-shaped groove.
[0021] The upper pressure block 4 is a rectangular module structure, and the upper pressure block 4 is connected to the upper front end face of the sub-pressure plate 2 by bolts.

[0023] One end of the connecting pin 6 is located in the middle and rear part of the sub-pressure plate 2, and the other end of the pin 6 passes through the sub-pressure plate 2 and connects to the side of the mother pressure plate 3.
[0024] The tail of the pull rod 7 is connected to the mother pressure plate 3 by bolts, and the head of the pull rod 7 is connected to the piston rod of the oil cylinder.
[0025] The head of the elastic plunger 8 is located at the front side of the lower part of the sub-pressure plate 2, and the tail of the elastic plunger 8 passes through the lower part of the sub-pressure plate 2 and is connected to the lower part of the sub-pressure plate 2 by bolts.
[0026] A limiting pin 9 is connected to the inner side of the middle part of the sub-pressure plate 2, and a limiting groove matching the limiting pin 9 is provided on the mother pressure plate 3.
[0027] The bottom side of the mother pressure plate 3 is connected to one end of the elastic plunger baffle 10 by bolts, and the other end of the elastic plunger baffle 10 is located in front of the elastic plunger 8; the elastic plunger baffle 10 has an L-shaped structure.
[0028] The mechanism of this utility model is set in the bracket clamp.

The two-point floating pressing action of the upper pressing block 4 and the lower pressing block 5 is completed.
