A support block 8 is fixedly connected to the bottom of the pull rod 7, and the pull rod 7 is used to drive the support block 8 to move. The left and right sides of the support block 8 are rotatably connected with an offset rod 9, and the support block 8 is used to drive the offset rod 9 to move. The opposite sides of the two offset rods 9 are rotatably connected with a clamping block 10, and the offset rod 9 is used to drive the clamping block 10 to move. The clamping block 10 is used to engage with the clamping slot 2 to achieve the combination and fixation of the building frame 1 and the base plate 3. A spring 11 is provided on the outside of the pull rod 7, and the pull rod 7 is used to prevent the spring 11 from deflecting. The spring 11 is used to continuously push the clamping block 10 to engage with the clamping slot 2 through the support block 8 and the offset rod 9. A connecting assembly is provided on the left and right sides of the base plate 3, and the top of the spring 11 is fixedly connected to the inside of the fixed block 6.

[0034] Reference Figure 1-3 The bottom of the spring 11 is fixedly connected to the top of the support block 8, which is used to make the thrust of the spring 11 on the support block 8 more stable. The bottom of the card block 10 is designed to be an inclined surface, which is used to be squeezed and retracted into the interior of the fixed block 6, and will not affect the insertion of the fixed block 6 into the interior of the building frame 1. The two card blocks 10 are slidably connected to the interior of the fixed block 6, and the fixed block 6 is used to limit the card blocks 10.

The limit groove cooperates with the limit block to prevent the block 16 from sliding out of the interior of the connecting block 14.

[0037] Working principle: When installing, you only need to move the bottom plate 3 to the top of the building frame 1, and then insert the six steel frames 4 into the internal slots of the building frame 1. When the inclined surface of the slot 2 contacts the slot of the building frame 1, it will be squeezed and moved into the interior of the fixed block 6. At the same time, the support block 8 will be driven by the offset rod 9 to squeeze the spring 11, so as not to prevent the fixed block 6 from being inserted into the interior of the building frame 1. When the fixed block 6 is completely inserted into the bottom plate 3, the spring 11 is reset, and the offset rod 9 is driven by the support block 8 to deviate and move, thereby driving the card block 10 to be inserted into the interior of the card slot 2 and engage with the card slot 2, and the installation can be completed.
