[0023] The tensioning component includes a spring 305 , one end of which is fixedly connected to the inner wall of the groove 303 , and the other end of which is fixedly connected to the fixing block 304 .

[0024] One side of the fixing block 304 is arranged in a plane, and the other side is arranged in an inclined manner.

[0025] When the multiple tube sheet bodies 1 are spliced ​​together by the clamping assembly, so that the multiple spliced ​​tube sheet bodies 1 form a tube body, and then the connecting blocks 302 on the pressure plate 301 are respectively inserted into the connecting grooves 3 on the inner walls of two adjacent tube sheet bodies 1, the tension at the connection between the two adjacent tube sheet bodies 1 is increased, thereby reducing the possibility of separation of the two adjacent tube sheet bodies 1. At the same time, when the connecting block 302 is inserted into the connecting groove 3, the fixing block 304 is squeezed by the inner wall of the connecting groove 3, and then retracts into the groove 303, and compresses the spring 304. 05, until the fixing block 304 is completely retracted into the groove 303, and when the connecting block 302 is completely inserted into the connecting groove 3, the groove 303 on the connecting block 302 coincides with the fixing groove 306 on the side wall of the connecting groove 3, and then the spring 305 is compressed to generate a thrust, pushing the fixing block 304 to move out of the groove 303 and insert it into the fixing groove 306, thereby achieving the purpose of limiting and fixing the connecting block 302, improving the firmness of the two adjacent tube sheet bodies 1 after being spliced ​​together, and effectively reducing the possibility of separation of the two adjacent tube sheet bodies 1.
