[0023] When the above-mentioned device is used, the valve block is first placed between the first clamping plate 4 and the second clamping plate 5 in the frame 3, and then the limit plate 603 is pinched and the screw 602 is rotated to make the second clamping plate 5 approach the first clamping plate 4 until the first clamping plate 4 and the second clamping plate 5 clamp the valve block. When the valve block needs to be rotated, the rotation of the rotating column 601 drives the telescopic rod 701 to rotate the second clamping plate 5. The rotation of the rotating column 601 will also drive the limit plate 603 to rotate. The rotation of the limit plate 603 will drive the annular teeth 607 to rotate the second gear 606. The rotation of the second gear 606 will drive the first gear 605 to rotate the rotating rod 604. The rotation of the rotating rod 604 will also drive another first gear 605 to rotate, and then drive another second gear 606 and the annular teeth 607 to make the first clamping plate 4 and the second clamping plate 5 rotate synchronously, thereby facilitating the direction of rotating the valve block. Example

[0024] See also Figures 1-4On the basis of embodiment 1, a limiting component 7 is provided on the left side of the limiting disk 603, and the limiting component 7 includes a telescopic rod 701.
