[0020] By adopting the above technical solution, when the fine-tuning screw is rotated, the clamping part moves in a direction close to or away from the fixing part under the limiting action of the fine-tuning slider, so that after the clamping and pressing member presses and fixes the steel edge waterstop, a slight adjustment of the position of the steel edge waterstop can be achieved by moving the clamping part, and the applicability is strong.

[0021] Optionally, the corners of the clamping seat are all arranged with arc-shaped transitions.

[0022] By adopting the above technical solution, when the staff applies force to move the clamping seat, it is not easy to cause scratches due to contact with the corners of the clamping seat, and the safety is enhanced.

[0025] 2. The setting of the limit plate plays a further role in limiting the movement of the clamping seat, so that the clamping seat is not easy to separate from the moving screw during movement, which is conducive to further ensuring the stability of the clamping seat during movement.

[0026] 3. When the fine-tuning screw is rotated, the clamping part moves toward or away from the fixing part under the limiting action of the fine-tuning slider, so that after the clamping and pressing part presses and fixes the steel edge waterstop, the position of the steel edge waterstop can be slightly adjusted by moving the clamping part, which has strong applicability.

[0032] Specifically, the fixed portion 101 is provided with a fine-tuning assembly that drives the clamping portion 102 to move closer to or away from the fixed portion 101, and the fine-tuning assembly includes a fine-tuning screw 2 and a fine-tuning slider 3, wherein one end of the fine-tuning screw 2 is rotatably mounted on a side of the clamping portion 102 close to the fixed portion 101, and the fixed portion 101 is integrally fixedly connected with a fine-tuning fixed block 4 corresponding to the fine-tuning screw 2, and the fine-tuning screw 2 is passed through the fine-tuning fixed block 4 and threadedly engaged with the fine-tuning fixed block 4. The fine-tuning slider 3 is fixedly mounted on a side of the clamping portion 102 facing the fixed portion 101, and the fine-tuning slider 3 is passed through the fixed portion 101 and slidably engaged with the fixed portion 101. When the fine-tuning screw 2 rotates, the clamping portion 102 moves in a direction closer to or away from the fixed portion 101 under the limiting action of the fine-tuning slider 3.

[0033] Continue to refer to Figure 1 , a placement groove 5 is provided on one side of the two clamping parts 102 adjacent to the fixing part 101, so as to realize the placement of the steel edge waterstop. Two groups of clamping and pressing parts are provided and correspond to the two clamping parts 102 respectively, and each group of clamping and pressing parts includes two pressing screws 6 arranged opposite to each other. The clamping part 102 is integrally fixedly connected with two pressing and fixing blocks, and the two pressing screws 6 are respectively passed through the two pressing and fixing blocks and are threadedly matched with the two pressing and fixing blocks. When one of the pressing screws 6 is screwed, the pressing screw 6 rotates in the direction of approaching or moving away from the other pressing screw 6. When the steel edge waterstop is located in the placement groove 5, the two pressing screws 6 are respectively located on both sides of the steel edge waterstop, so that the two pressing screws 6 can respectively realize the pressing and fixing of the two sides of the steel edge waterstop in the placement groove 5.

[0034] In order to fully ensure the stability of the two pressing screws 6 when pressing and fixing the steel edge water stop, a clamping plate 7 is fixedly connected to the opposite side of the two pressing screws 6. The cross-sectional size of the clamping plate 7 is larger than the cross-sectional size of the pressing screw 6 to increase the contact area of ​​the pressing screw 6 when pressing and fixing the steel edge water stop. In order to facilitate the application of force to realize the rotation of the pressing screw 6, a pressing handle 8 is fixedly connected to the ends of the two pressing screws 6 that are far away from each other.

[0035] Continue to refer to Figure 1 The clamping moving part includes a moving screw 9 and a moving guide rod 10, wherein the moving screw 9 is rotatably mounted on a fixed portion 101 of one of the clamping seats 1, and the moving screw 9 is passed through and threadedly matched with the fixed portion 101 of the other clamping seat 1.
