The near ends of two sets of metal rods are fitted over the upper outer sides of the rivets. The two sets of metal rods are then placed in the placement slots of two sets of support frames. The metal rods can contact the locking blocks. Pressing down on the metal rods pushes the locking blocks, causing them to retract into the inner side of the movable slot. During movement, the locking blocks compress the spring. When the metal rods are fully installed inside the placement slots, they separate from the locking blocks, which then automatically extend under the elastic force of the spring, locking onto the upper side of the metal rods. This design limits the installation of the metal rods inside the placement slots. To improve the installation stability of the metal rods, the support frame supports the metal rods to maintain their stable placement. The riveting head rotates and presses the upper end of the rivet to achieve riveting between two sets of metal rods. An internal thread rotating block is movably mounted on the upper end of the fixed cylinder via a bearing, and the internal thread rotating block is threadedly connected to the threaded rod. Rotating the internal thread rotating block drives the threaded rod to move within the fixed cylinder, which in turn drives the support frame to rise and fall.
