When the transverse clamping mechanism 2 clamps the object, the object contacts the telescopic block 311, and the telescopic block 311 drives the movable rod 33 to retreat, and causes the spring 34 to contract in the limit block 35. At the same time, the fixed rod 36 on the surface of the movable rod 33 retreats, driving the second adjusting rod 38. The first adjusting rod 37 moves and limits the moving direction of the second adjusting rod 38. The rod 38 drives the clamping rod 39 to clamp the object. At the same time, when the object is fixed by the horizontal clamping mechanism 2, the second cylinder 42 pushes the second cylinder shaft 43 to press down and clamp the object, further fixing the object, thereby improving the stability of the device. The rubber pad 44 prevents the object from being damaged, and the wear-resistant plate 15 reduces the wear of the device during use. After use, the first cylinder shaft 27 and the second cylinder shaft 43 are retracted, and the slider 25 slides to drive the second vise side plate 23 to reset. When the horizontal clamping mechanism 2 releases the object, the spring 34 rebounds, and when the baffle 32 contacts the limit block 35, the entire mechanism reaches the initial position, so that the fixing mechanism 3 is reset, the object is released, and the adaptability of the device is improved.
