[0029] Please refer to Figure 8 , and the clamping block 26 includes support block 261, and the bottom end of support block 261 and sliding plate 25 end are attached, and the outer end of support block 261 and the outer end of sliding plate 25 are even, and the one side of support block 261 near fixed block 24 is provided with top block 262, and top block 262 is adapted to clamping groove 23, when top block 262 moves to the inside of clamping groove 23, stopper 22 is positioned to top block 262, makes top block 262 unable to move outward.

[0030] Please refer to Figure 3 、 Figure 4The guide assembly 3 includes guide grooves 31 disposed at both ends of the E-shaped silicon steel sheet 11. The guide grooves 31 are hollow structures with one open side and the other inclined side. A limiting groove 32 is provided at one end of the guide groove 31 near the outer side of the E-shaped silicon steel sheet 11. A guide block 33 is disposed inside the guide groove 31. The guide block 33 is in the shape of a right trapezoid. The side of the guide block 33 forms an angle with the inner wall of the limiting groove 32. The angle value of this angle is between 10° and 30°. A limiting block 34 is provided at the outer end of the guide block 33. The limiting block 34 is adapted to the limiting groove 32, and the outer side of the limiting block 34 is aligned with the inner wall of the limiting groove 32. The outer sides of the type I silicon steel sheet 13 are flush. The guide block 33 is fixedly connected to the middle of both ends of one side of the type I silicon steel sheet 13. The type E silicon steel sheet 11 and the type I silicon steel sheet 13 are also provided with corresponding first mounting holes 12 and second mounting holes 14. When the type I silicon steel sheet 13 approaches the type E silicon steel sheet 11, the front end of the guide block 33 moves to the outer end of the guide groove 31. Since the length of the outer end of the guide groove 31 is greater than the length of the outer end of the guide block 33, the guide block 33 can easily enter the interior of the guide groove 31 and align with the type E silicon steel sheet 11 under the guidance of the guide groove 31.

[0031] Please refer to it again. Figures 1 to 8 In use, when stacking silicon steel sheet assemblies 1, the E-type silicon steel sheet 11 and the I-type silicon steel sheet 13 are spliced together. During the splicing process, the guide block 33 slides inside the guide groove 31. Since the guide groove 31 has a trapezoidal structure, it can guide the guide block 33. The side corner of the guide block 33 contacts the inner wall of the guide groove 31, thereby reducing the friction between the guide block 33 and the guide groove 31. When the guide block 33 drives the limiting block 34 to move into the limiting groove 32, the E-type silicon steel sheet 11 and the I-type silicon steel sheet 13 can be quickly spliced together. After the E-type silicon steel sheet 11 and the I-type silicon steel sheet 13 are spliced together, the I-type silicon steel sheet 13 is moved to fix it. Block 24 moves into the fixed groove 21 and then horizontally pushes the upper I-shaped silicon steel sheet 13. The I-shaped silicon steel sheet 13 drives the sliding plate 25 to slide inward along the fixed groove 21. The movement of the sliding plate 25 can cause the upper I-shaped silicon steel sheet 13 and the lower E-shaped silicon steel sheet 11 to fit together, making them stacked tightly. Then, the upper I-shaped silicon steel sheet 13 is pushed vertically, causing the fixed block 24 to move vertically. The fixed block 24 drives the support block 261 and the top block 262 to move into the slot 23 through the sliding plate 25. The top block 262 engages with the slot 23, causing the stop block 22 to block the top block 262 and the support block 261, preventing the sliding plate 25 from sliding outward, thus preventing the upper I-shaped silicon steel sheet 13 and the lower E-shaped silicon steel sheet 11 from becoming loose.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
