Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] A typical embodiment of this utility model is as follows: Figure 1 As shown, a stop frame structure includes a positive stop frame 1 and a negative stop frame 2, with one end of the negative stop frame 2 being inserted into one end of the positive stop frame 1.

[0025] like Figure 2 As shown, the positive electrode stop frame 1 has a first positive electrode cavity 3 and a second positive electrode cavity 4. A spacer plate 5 is provided between the first positive electrode cavity 3 and the second positive electrode cavity 4. A positive electrode rivet hole 6 is provided on the bottom surface of the first positive electrode cavity 3. An injection hole 7 is provided on the bottom surface of the second positive electrode cavity 4. The positive electrode stop frame 1 is also provided with a positive electrode platform 8 and a stop platform 9. The positive electrode platform 8 is located at the end of the first positive electrode cavity 3 away from the second positive electrode cavity 4. The stop platform 9 is located at the end of the second positive electrode cavity 4 away from the first positive electrode cavity 3. Multiple positive electrode exhaust holes 10 are provided side by side on the positive electrode platform 8. A grille 11 is provided on the stop platform 9.

[0026] A second negative electrode cavity 12 is provided on the side of the stop platform 9 away from the second positive electrode cavity 4. A insertion groove 13 is provided on the bottom surface of the second negative electrode cavity 12 away from the stop platform 9. The insertion groove 13 is set lower than the bottom surface of the second negative electrode cavity 12, and the width of the insertion groove 13 is greater than the width of the bottom surface of the second negative electrode cavity 12, so that the two sides of the insertion groove 13 extend into the side wall of the second negative electrode cavity 12.

[0027] like Figure 3 As shown, a first negative electrode recess 14 is provided on the negative electrode stop bracket 2. A negative electrode rivet hole 15 is provided on the bottom surface of the first negative electrode recess 14. A negative electrode platform 16 is provided at one end of the first negative electrode recess 14. Multiple negative electrode exhaust holes 17 are arranged side by side on the negative electrode platform 16. A plug-in plate 18 is provided at the end of the first negative electrode recess 14 away from the negative electrode platform 16. The plug-in plate 18 is adapted to the plug-in groove 13 so that the plug-in plate 18 can be placed in the plug-in groove 13, and the top surface of the plug-in plate 18 is flush with the bottom surface of the second negative electrode recess 12.

[0028] Since the two sides of the insertion slot 13 extend into the side wall of the second negative electrode cavity 12, when the insertion plate 18 is inserted into the insertion slot 13, the two sides of the insertion plate 18 are located inside the side wall of the second negative electrode cavity 12, thereby limiting the insertion plate 18.

[0029] This invention provides a plug-in slot at one end of the positive electrode stop frame and a plug-in plate at one end of the negative electrode stop frame. The plug-in slot and the plug-in plate enable the plug-in connection between the positive and negative electrode stop frames.
