[0020] Reference Figures 1-5As shown in the figure, a connection mechanism between an electric kettle thermostat and a spring 2 in this embodiment includes a connecting base 1 and a spring 2 disposed on the connecting base 1. The connecting base 1 has a plurality of connecting holes 11, and a receiving groove 3 is provided at the lower end of the connecting base 1. The receiving groove 3 communicates with the connecting holes 11. The spring 2 is disposed in the receiving groove 3, and a locking groove 31 is provided in the receiving groove 3. The spring 2 has a locking hole 21, the position of which corresponds to the position of the locking groove 31. A locking screw 32 is provided in the locking groove 31, and the locking screw passes through the locking groove 31. The fixed hole 21 is threadedly connected to the locking groove 31. The receiving groove 3 has locking protrusions 4 on both sides. There is a receiving recess 41 between the locking protrusions 4 and the bottom of the receiving groove 3. The spring 2 has a first protrusion 22 on both sides. The first protrusion 22 is located in the receiving recess 41 and abuts against the locking protrusion 4. The bottom of the receiving groove 3 has a second positioning groove 5. The spring 2 has a second positioning part 23. The second positioning part 23 bends toward the second positioning groove 5 and is located in the second positioning groove 5. The second positioning part 23 is misaligned with the first protrusion 22.

[0021] With the above technical solution, before the fixed installation of the connecting seat 1 and the spring 2, the spring 2 and the connecting seat 1 are initially fixed by stamping. During the stamping process, part of the spring 2 is bent and deformed, and is initially fixed with the connecting seat 1. This makes the position of the spring 2 and the connecting seat 1 stable and without loosening during the subsequent screwing process to fix the spring 2 and the connecting seat 1. There is no need to hold the spring 2 while tightening the fixing screw, thereby improving production efficiency.

[0022] Specifically, during stamping, the stamping equipment stamps the spring 2 into the receiving groove 3, and 1. stamps the first protrusion 22 into the receiving recess 41; 2. stamps part of the spring 2 to form a second curved part, which is located in the second positioning groove 5; 3. causes the third positioning block 6 to be embedded in the third positioning notch 24; 4. causes the second positioning ear 25 to fold and be inserted into the second auxiliary groove 51; the spring 2 and the connecting seat 1 are fixed from multiple directions, so that the spring 2 and the connecting seat 1 are initially fixed with higher stability, and after tightening the locking screw 32, the position of the spring 2 is stable and the service life is long.

[0023] As an improved specific implementation, the spring 2 is provided with a third positioning notch 24 between the first protrusion 22 and the second positioning part 23, and the receiving groove 3 is provided with a third positioning block 6, which is embedded in the third positioning notch 24.

[0024] Through the above technical solution, after the spring 2 and the connecting seat 1 are initially fixed, the third positioning block 6 is inserted into the third positioning notch 24 and cooperates with the first protrusion 22 and the receiving recess 41 to fix the spring 2 and the connecting seat 1 at multiple angles, thereby improving the stability and structural strength of the spring 2 and the connecting seat 1 after they are fixed and preventing the spring 2 and the connecting seat 1 from becoming loose.

[0025] As an improved specific implementation, the upper end of the third positioning block 6 is provided with an inclined third guide edge 61.

[0026] By using the above technical solution, when the spring 2 and the connecting seat 1 are initially fixed, the third guide edge 61 guides the spring 2 at the position of the third positioning notch 24 to enter, thereby improving the stability of the initial fixing process between the spring 2 and the connecting seat 1.

[0027] As an improved specific implementation, the second positioning groove 5 is provided with a second auxiliary groove 51 on both sides, and the spring 2 is provided with a second positioning ear 25, which is located in the second auxiliary groove 51.

[0028] Through the above technical solution, during the initial fixing process of the spring 2 and the connecting seat 1, the die stamping causes the second positioning ear 25 to bend into the second auxiliary groove 51, which cooperates with the second positioning part 23, the second positioning groove 5, the first protrusion 22, and the receiving recess 41, further improving the stability of the spring 2 and the connecting seat 1 after initial fixing, and preventing the spring 2 and the connecting seat 1 from loosening during the subsequent bolt tightening process.

[0029] As an improved specific implementation, the locking protrusion 4 is provided with an inclined first guide edge 42.

[0030] With the above technical solution, when the spring 2 and the connecting seat 1 are initially fixed, the first guide edge 42 guides the first protrusion 22 into the receiving recess 41, so that the proposed protrusion remains arc-shaped after entering the receiving recess 41, and can stably abut against the locking protrusion 4, thereby maintaining its position and improving the stability in the subsequent installation process.

[0031] As an improved specific implementation, the reed 2 is provided with a fourth abutment part 26, which is misaligned with the connecting hole 11, and the fourth abutment part 26 abuts against the connecting seat 1.

[0032] Through the above technical solution, the fourth contact part 26 abuts against the connecting seat 1, so that the positions of the spring 2 and the connecting seat 1 in multiple directions are fixed and restricted, avoiding the spring 2 and the connecting seat 1 from loosening during the screw tightening process, and improving the stability during the installation process.

[0033] As one specific embodiment of the improvement, the spring 2 is integrally formed and the connecting seat 1 is integrally formed.

[0034] Through the above technical solution, the spring 2, the first protrusion 22, the fourth contact part 26, and the second positioning ear 25 are integrally molded, resulting in high structural strength, good fatigue resistance, and high production efficiency; the connecting seat 1 is integrally injection molded, resulting in high structural strength, high stability, and high production efficiency.
