[0033] Working principle: First, the main structure of the throat clamp is composed of a steel ring 1 and a clamping block 2. A clamping strip 1 7 and a clamping strip 2 8 are respectively arranged at both ends of the steel ring 1. The outer end of the clamping strip 2 8 is fixedly sleeved with a clamping block 2. The clamping strip 1 7 and the clamping strip 2 8 are meshed and connected by a gear block, which allows them to move relative to each other, thereby realizing the adjustment function of the throat clamp. When the push button 1 4 is pressed, the screw rod 11 moves downward, pushing the connecting plate 13 and the limit plate 9 downward together. Since the lower end of the limit plate 9 is fixedly installed with an anti-lock The anti-skid pad 10 is in contact with the upper end of the card strip 7. Therefore, when the limit plate 9 moves downward, it will apply downward pressure to the card strip 7 through the anti-skid pad 10, so that it is tightly engaged with the card strip 2 8, thereby fixing the throat clamp. At the same time, the return spring 12 is sleeved on the screw rod 11, and its two ends are respectively connected between the pressing key 4 and the clamping block 2. When the pressing key 4 is released, the elastic force of the return spring 12 will make the screw rod 11, the connecting plate 13 and the limit plate 9 return to their original positions. When the push button 26 is pressed, the guide rod 17 moves downward, and the conical plate 19 at the bottom of the guide rod 17 contacts the push rod 20, thereby pushing the push rod 20 to move inward. Since the push rod 20 is connected to the inside of the fixed block 23 through the limit spring 21, when the push rod 20 is pushed, the limit spring 21 is compressed, and at the same time, the push rod 20 moves forward. The circular ring 22 at the end interacts with the support plate 14, pushing the support plate 14 to move upward in the U-shaped groove. The upward movement of the support plate 14 is transmitted to the connecting plate 13 through the connecting rod 15, thereby driving the limit plate 9 and the anti-skid pad 10 fixed at the lower end of the limit plate 9 to rise. As the anti-skid pad 10 rises, it gradually moves away from the upper end of the card strip 1 7, releasing the downward pressure on the card strip 1 7. Therefore, the meshing state between the card strip 1 7 and the card strip 2 8 is released, and the throat clamp can be freely adjusted.
