[0025] according to Figures 1 to 4 A clamp-type pressure cooker comprises a pot body 1, a pot cover 2, a clamp assembly 3, a panel 4, a knob assembly 5, and a rotating groove 6. The pot cover 1 is fixed with a panel 4, and a knob assembly 5 is arranged on the top of the panel 4. The knob assembly 5 is linked and fixed with the clamp assembly 3. A rotating groove 6 is arranged at the center of the panel 4, and the knob assembly 5 is fixed in the rotating groove 6. The knob assembly 5 drives the clamp assembly 3 to open or close through a rotating mechanism; the improvement thereof is that two fan-shaped limit blocks 7 are arranged at the bottom of the knob assembly 5, and correspondingly, a baffle 8 is arranged along the midline of the rotating groove 6 to divide it into two semicircular grooves 9, which cooperate with the respective fan-shaped limit blocks 7 so that they can rotate appropriately but cannot rotate excessively.

[0026] The top of the panel 4 is provided with a steel ball spring hole 10 at the outer edge of the rotating groove 6. The steel ball spring hole 10 is provided with a spring 12 and a steel ball 14. Correspondingly, the bottom of the knob assembly 5 is provided with a positioning hole 17, which cooperates with the steel ball spring to achieve the positioning function, so that the clamp assembly 3 is in an open state or a closed state, and cannot slide easily. At the same time, it can also prevent the knob assembly 5 from excessive rotation and causing damage. The top of the panel 4 is provided with a damping body spring hole 11 at the outer edge of the rotating groove 6, directly opposite the steel ball spring hole 10. The damping body spring hole 11 is provided with a spring 12 and a damping body 13. The head of the damping body 13 adopts a cone shape. Correspondingly, the bottom of the knob assembly 5 is provided with a damping groove 15. The damping groove 15 adopts an arc shape. The damping friction strip 16 is distributed in the damping groove 15, which cooperates with the damping body spring 12 to achieve the damping function, providing users with good vibration feedback and improving the feel of use.

[0027] The clamp assembly 3 includes a clamp 18 and a connecting plate 19. The connecting plate 19 is fixed to one end of the clamp 18.

The connecting rod 21 passes upward through the arc-shaped guide hole 31 in the rotating groove 6 of the panel 4 and is connected and fixed to the bottom connecting hole 22 of the knob assembly 5. The connecting plate 19 is provided with a gourd hole 23 formed by connecting large and small holes, which is sleeved on the float safety valve 24 and matches the diameter of the float safety valve 24 at different lifting positions. When the pot pressure is within the safe pressure range and the connecting plate 19 moves, the float safety valve 24 will not affect the movement of the moving plate 19.

[0028] The bottom of the pot cover 2 is provided with a mounting groove 27, and the bottom of the mounting groove 27 has a valve hole 32. The valve stem 28 is fixed by an elastic seal 33 and locked with a nut 34 below. The upper part of the valve stem 28 is provided with a slide groove surface 29 that matches the strip hole 30 on the connecting plate 19 to achieve a limited sliding function, so that the valve stem of the explosion-proof pressure relief valve acts as a guide rod. A through hole 25 is provided in the middle of the rotating groove 6, and a fixing hole 20 is provided at the bottom of the knob assembly 5. The bolt 26 passes through the through hole of the rotating groove 6 and the fixing hole 20 at the bottom of the knob assembly 5, so that the knob assembly 5 and the rotating groove 6 are rotatably fixed together.

[0029] When the user needs to use this product to open or close the pot lid 2, he only needs to rotate the knob assembly 5 by hand, and the connecting rod 21 at the bottom of the knob assembly 5 will drive the connecting plate 19 to move horizontally to both ends respectively, thereby completing the function of the telescopic clamp 18, and a fan-shaped limit block 7 is provided at the bottom of the knob assembly 5 to cooperate with the semicircular groove 9, so as to increase the service life of the connecting rod 21 and prevent the user from rotating too hard to cause damage to the connecting rod 21, and a steel ball spring hole 10 is provided on the panel 4, which cooperates with the positioning hole 17 on the knob assembly through the spring 12 and the steel ball 14, so as to achieve the positioning function. When the user opens and closes to a certain extent, it will prevent the pot lid from moving accidentally.
