[0030] Preferably, the pressing mechanism comprises a sliding frame 5 and a sliding block 6 slidingly arranged on the sliding frame 5, and a resilient member 7 is arranged between the sliding block 6 and the sliding frame 5, and the pressing roller 8 is rotatably arranged on the sliding block 6. Specifically, the sliding frame 5 is vertically arranged on the connecting rod 4, the lower end of the sliding frame 5 is provided with a sliding groove 9, the sliding block 6 is slidingly arranged in the sliding groove 9, the sliding block 6 is in the shape of a Chinese character, and the pressing roller 8 is rotatably arranged between the two side walls of the sliding block 6, the resilient member 7 is arranged in the sliding groove 9, and the resilient member 7 is preferably a spring, one end of which is fixedly connected to the inner top wall of the sliding groove 9, and the other end is fixedly connected to the upper surface of the sliding block 6. When the caulking tape mechanism is working, the pressing roller 8 is always on the spreading route of the caulking tape body 1. When the bridge surface is uneven, for example, when the bridge surface is convex, the resilient member 7 is compressed to make the sliding block 6 move upward with the pressing roller 8, that is, the caulking tape body 1 has a downward force. Similarly, when the bridge surface is sunken, the resilient member 7 releases its elastic force to make the sliding block 6 move downward with the pressing roller 8, that is, the caulking tape body 1 has a downward force. The purpose of such arrangement is that when the working route of the caulking tape mechanism is uneven, the pressing roller 8 always has a downward force on the caulking tape body 1, thereby enhancing the adhesion of the caulking tape body 1 on the bridge surface.

[0031] Further, a vertical slot is formed in the connecting rod 4, and the sliding frame 5 is slidingly connected to the vertical slot. Specifically, the vertical slot is arranged on the vertical section of the connecting rod 4, and the sliding frame 5 can be regarded as a first section 501 and a second section 502, the first section 501 is slidingly arranged in the vertical slot, and the sliding frame 5 is in the shape of a rectangular plate, which is vertically slidingly arranged in the vertical slot.
