[0026] Working principle: When using, when it is necessary to use multiple bases 6 in combination, first pull the clamping block 7 horizontally, the clamping block 7 drives the connecting block 82 and the sliding seat 83 to move, the sliding seat 83 drives the sliding block 84 to slide along the fixing rod 85, the sliding block 84 squeezes the first spring 86, and then any number of bases 6 are placed in the connecting seat 3 and the plug-in block 5 is inserted into the slot 4, the adjacent bases 6 contact each other, and then the clamping block 7 is slowly released, the clamping block 7 will reset and move under the elastic action of the first spring 86, so that the clamping block 7 drives the limiting block 81 to move and insert into the base 6. At this time, the first spring 86 is still in a compressed state, which will give the clamping block 7 a continuous thrust, so that the limiting block 81 keeps in contact with the base 6, and the horizontal position of the base 6 can be limited by plugging the plug-in block 5 into the slot 4. At the same time, the vertical direction of the base 6 can be limited by plugging the limiting block 81 into the base 6, so that it is convenient to install and use any number of bases 6 in combination, and the connection method is more convenient and quick.
