[0025] The connecting assembly 8 comprises a fixing sleeve 801 arranged on the first floating cover 6, which is fixedly installed on the top of the first floating cover 6 and communicates with the first floating cover 6. The inside of the fixing sleeve 801 is provided with an insertion rod 802, which is inserted into the fixing sleeve 801. The outside of the insertion rod 802 is provided with a spring 803, which is sleeved on the outside of the insertion rod 802. The top of the spring 803 is installed on the top of the inner cavity of the fixing sleeve 801. The bottom of the insertion rod 802 is provided with a plug 804, which is fixedly installed on the bottom of the insertion rod 802. The inside of the clamping block 10 is provided with an insertion hole 806, which is formed in the clamping block 10. The connecting assembly 8 further comprises a limiting cover 805 rotatably installed on the top of the insertion rod 802 through a connecting shaft. The insertion rod 802 penetrates through the fixing sleeve 801 and extends into the clamping groove 9. When two first floating covers 6 are connected, the right first floating cover 6 with the clamping block 10 is inserted into the clamping groove 9 of the other first floating cover 6. The clamping block 10 moves upwards against the plug 804, compresses the spring 803, and then the plug 804 is inserted into the insertion hole 806. At this time, the spring 803 resets to limit the plug 804 in the insertion hole 806, so as to limit the clamping block 10 in the clamping groove 9. When pulling out, the limiting cover 805 is turned over to stand on the top of the fixing sleeve 801, and the insertion rod 802 is lifted, so that the clamping block 10 can be taken out of the clamping groove 9.

[0026] The clamping assembly 11 comprises an installation plate 1101 arranged in the clamping groove 9, which is fixedly installed in the clamping groove 9.
