The upper end of the limiting column 15 is fixedly installed on the lower side of the limiting plate 3, and both sides of the mounting plate 11 are fixed by the limiting plate 3 and the limiting column 15; the limiting plate 3 is rotatably installed inside the rotation groove 13, the inner end of the limiting plate 3 is provided with a rectangular groove 16, and the rectangular block 18 is tightly fitted on the upper surface of the limiting plate 3, which is convenient for quick disassembly and installation, and the structure is simple and easy to operate, and the installation is stable and reliable.

[0029] Specific working principle:

[0030] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, when using the quick-release transformer, install the mounting base 2 with the equipment that needs to be installed and fixed. After the mounting base 2 is installed, take out the transformer body 1 that needs to be used, align the mounting plate 11 on the lower side of the transformer body 1 with the engaging grooves 14 on both sides, push the transformer body 1 backward, so that the two ends of the mounting plate 11 are engaged with the inner sides of the engaging grooves 14, and then rotate the limit plate 3 downward. When the limit plate 3 is rotated downward, the limit column 15 drives the limit column 15 to engage with the inner side of the limit hole 12. When the limit plate 3 is rotated downward, the horizontal rectangular block 18 and the threaded rod 17 pass through the rectangular groove 16 at the same time. After the limit column 15 is engaged with the inside of the limit hole 12, pinch the rectangular block 18 and rotate it ninety degrees to rotate the horizontal rectangular block 18 to the vertical direction. The rectangular block 18 can limit the limit plate 3, and the limit plate 3 cannot be rotated open. At the same time, the threaded rod 17 is threadedly connected to the inner end of the mounting seat 2. When the rectangular block 18 and the threaded rod 17 are rotated clockwise to lock, the thread is rotated downward, so that the rectangular block 18 and the limit plate 3 fit more firmly and tightly. After using the terminal 6 for wiring, take out the protective cap 8, and engage the rear end of the protective cap 8 with the rubber strip 9 into the inside of the card slot 7, and install the protective cap 8. The protective cap 8 covers the outside of the terminal 6, and the wire is led out from the opening 10 to protect and reinforce the terminal 6. The above completes a series of operations of the quick-release transformer. The content not described in detail in this description belongs to the prior art known to professional and technical personnel in this field.
