[0035] As a further implementation of the present scheme, the dovetail groove 32 is through one end of the sleeve shell 31, the dovetail groove 32 is shaped as a trapezoidal body, the embedded block 34 near one end of the dovetail groove 32 is shaped as a trapezoidal body, the contact head 35 is in electrical communication with the resistance wire 33, one end of the push rod 37 is fixedly connected with one side of the metal arc plate 47, the moving distance of the slide column 42 is detected by the electrical detection assembly 3, thereby determining the pressure of the rubber pad 48 on the inner liner of the electric rice cooker;

[0037] Workflow: when the electric rice cooker liner is fixed, prevent damage to the electric rice cooker liner, connect 38 to the existing control negative electrode, and connect the other end of the resistance wire 33 to the positive electrode of the controller. At this time, place the electric rice cooker between the multiple rubber pads 48, start the servo motor 12 to drive the rotating disc 13 and the first triangular plate 14 to rotate. Under the extrusion of the first triangular plate 14, the first triangular plate 14 pushes the second triangular plate 21 to move towards the electric rice cooker liner. The second triangular plate 21 drives the guide slide plate 22, the vertical plate 23, the electrical detection assembly 3 and the clamping assembly 4 to move as a whole. The guide slide plate 22 is slidingly connected inside the guide groove 17 opened in the convex bracket 16. The guide slide plate 22 limits the movement of the electrical detection assembly 3 and the clamping assembly 4 as a whole. When the rubber pad 48 contacts the electric rice cooker liner, it pushes the metal arc plate 47, the slide column 42 and the push rod 37 to move under the action of the reaction force. The slide column 42 is slidingly connected inside the oil groove 44 opened in the cylinder shell 41. The sealing of the rubber ring 43 can prevent the hydraulic oil from overflowing between the cylinder shell 41 and the slide column 42. The slide column 42 extrudes the spring 45. According to Hooke's law, the longer the spring 45 is compressed, the greater the spring force. The electrical detection assembly 3 detects the compression distance of the spring 45. In this process, the hydraulic oil in the oil groove 44 enters the liquid passage 25 through the communication oil port 46, and enters the air bag 24 through the electromagnetic valve 26. At this time, the air bag 24 expands, and the air bag 24 stores the hydraulic oil. The greater the expansion volume of the air bag 24, the greater the pushing force on the slide column 42. At this time, the deformation length of the spring 45 is proportional to the expansion volume of the air bag 24. The spring force of the spring 45 plus the deformation force of the air bag 24 is the pressure on the electric rice cooker liner. When the metal arc plate 47 drives the push rod 37 and the embedded block 34 to move, the communication flexible wire 36 is excited, the embedded block 34 drives the contact head 35 to move, and the position between the contact head 35 and the resistance wire 33 changes constantly. The embedded block 34 is slidingly connected to the inside of the dovetail groove 32, which can improve the stability of the metal arc plate 47 when it moves, and prevent the metal arc plate 47 from twisting. The controller detects the resistance value of 38, the contact head 35 and the resistance wire 33. The resistance value is inversely proportional to the spring force of the spring 45 plus the expansion force of the air bag 24, so as to calculate the pressure on the electric rice cooker in real time. When the pressure reaches a certain value, the electromagnetic valve 26 is closed. At this time, the distance between the slide column 42 and the cylinder shell 41 cannot be moved, so as to prevent the electric rice cooker liner from moving when the electric rice cooker liner is processed.

[0038] Although the embodiments of the present application have been shown and described, it should be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
