Copper C clamp is based on the specific working principle of the spiral mechanical transmission system and the lever principle

Copper C Clamp is a commonly used fixing tool, which is widely used in woodworking, metal processing, electrical welding and other fields. Its unique design and material enable it to show good performance in complex working environments. The following will introduce in detail how the Copper C clamp works based on the spiral mechanical transmission system and the lever principle to ensure that it can fix the workpiece efficiently and firmly.

1. Working principle of spiral mechanical transmission system
The core working principle of the Copper C clamp relies on the spiral mechanical transmission system. The screw, thread, handle and clamping plate constitute an important part of this system. The screw drives the clamp to clamp or loosen by rotating the handle.
The role of the screw: The screw is a key component in the C clamp, which passes through the middle of the C frame. During operation, the screw generates a linear motion of forward or backward by rotating the handle. The handle is connected to the screw, and the screw is driven by the thread, so that the screw can move forward or backward.
The transmission efficiency of the thread: The thread design on the screw is an important part of this transmission system. The thread is usually designed to be fine and dense, which means that when the handle rotates one circle, the screw moves forward a small distance, but the force generated is large. Due to the mechanical transmission efficiency of the thread, the handle does not feel too much resistance during rotation, but can apply a large clamping force.
Handle rotation and force transmission: When the user rotates the handle clockwise, the screw will move forward along the thread trajectory and gradually press the workpiece. Conversely, when the handle is rotated counterclockwise, the screw will retreat, thereby loosening the workpiece. This process is achieved through the friction and transmission efficiency of the thread, converting the rotational motion of the handle into a linear clamping or loosening action of the screw.

2. Application of the lever principle
In the work of the copper C-shaped clamp, the lever principle is another key to applying clamping force. The lever principle uses the force transfer mechanism to convert a small force into a larger force, thereby enhancing the fixing effect of the clamp.
The basic principle of the lever: The lever principle is based on the balance formula of "force arm × force = resistance arm × resistance". The handle, as the long arm of the lever, produces a larger force output by applying a smaller force. This allows the user to generate sufficient clamping force with a smaller rotational force when operating the handle, ensuring that the clamp can firmly fix the workpiece.
Leverage effect of the handle: The length of the handle determines the lever arm. The longer the handle, the less force the user applies, but the greater the clamping force generated. This means that when the user rotates the handle, they do not need to spend too much effort to clamp the workpiece tightly. The lever principle effectively reduces the difficulty of operation and improves the efficiency of the clamp.
Transmission and concentration of force: During the rotation of the handle, the lever principle concentrates the force at the end of the screw, and the active pressure plate of the clamp is in direct contact with the workpiece. This design ensures that the applied force can be evenly distributed on the surface of the workpiece, which can not only firmly fix the workpiece, but also avoid damage to the workpiece caused by excessive local force.

3. Combination of spiral mechanical transmission system and lever principle
The working principle of the Copper C-shaped clamp is efficient because it cleverly combines the spiral mechanical transmission system with the lever principle. The threaded transmission system provides precise mechanical control, while the lever principle converts small forces into large forces, achieving a higher clamping effect.
Efficient mechanical conversion: When the user rotates the handle, the screw mechanical transmission system will accurately control the advancement distance of the screw, and the lever principle ensures that the small force applied by the handle can be converted into a strong clamping force. The screw transmission system ensures the linear transmission of force, and the lever principle further amplifies the effect of the force through the length of the handle.
Gradual application of clamping force: Through the gradual advancement of the screw, the clamp can accurately control the clamping process to avoid damaging the workpiece by applying too much pressure at one time. The combination of screw transmission and lever principle enables the clamp to apply sufficient clamping force without damaging the workpiece, ensuring the stability of the workpiece during processing.
Easy operation and outstanding effect: The combination of the screw transmission system and the lever principle allows the operator to easily achieve a firm fixation of the workpiece by simply rotating the handle. Whether it is used for welding, cutting or assembly, the Copper C-shaped clamp can provide users with a stable clamping effect, and is easy to operate without the need for complex tools or techniques.
