This helps to maintain the accuracy and stability of the fixture and ensure the accuracy of workpiece positioning. The design of the T-nut 8 through the combined embedded ring 10 simplifies the installation and maintenance process of the fixture. Since the nut is limited to a fixed position, the operator does not need to worry about the position adjustment or fixation of the nut during installation or maintenance, saving time and energy. The T-nut 8 is fixed on the lower base plate 4, which reduces the friction and vibration between the nut and other components and extends the service life of the nut. This helps to reduce the maintenance cost of the clamp and improve the durability and reliability of the clamp. Since the T-nut 8 is limited to the lower base plate 4, it will not take up additional space, which helps to maintain the compactness and simplicity of the overall structure of the clamp. This is particularly important in a limited space working environment and can improve work efficiency and safety.

This manual control method can achieve more accurate positioning and angle adjustment, and is suitable for scenes requiring high-precision processing or assembly. The design of the adjustment rod 2 makes the operation more intuitive and simple. The operator only needs to gently rotate the adjustment rod 2 to achieve the rotation of the upper base plate 6, without the need for complicated operating steps or professional training. This simple operation method can improve work efficiency and reduce operating errors. Due to the direct control of the adjustment rod 2, the operator can make adjustments and corrections as needed in real time. This means that during the processing or assembly process, if the position or angle of the workpiece needs to be fine-tuned, the adjustment can be made immediately without stopping the entire operation process. The design of the adjustment rod 2 makes this clamp suitable for workpieces of various shapes and sizes. Whether it is a small part 1 or a large component, it can be easily positioned and rotated by the adjustment rod 2, which improves the versatility and scope of application of the clamp.

This means that the fixture can be quickly and accurately adjusted to the required angle to ensure the correct positioning and angle of the workpiece during processing or assembly. The design of the pointing block 3 and the angle scale line 5 makes the operation more intuitive and simple. The operator only needs to rotate the upper base plate 6 to the required angle according to the mark on the angle scale line 5, and align the pointing block 3 with the required position to complete the determination of the relative position without complicated operating steps or professional training. Since the relative position can be determined quickly and accurately, it means that the operator can position and adjust the angle of the workpiece more quickly, thereby improving work efficiency. Especially for work that requires frequent angle adjustment, this design can save a lot of time. The design of the pointing block 3 and the angle scale 5 can help reduce human errors. The operator only needs to align the pointing block 3 and the angle scale 5 according to the mark to ensure that the position and angle of the fixture are accurate, thereby reducing processing or assembly errors caused by operating errors.
