[0019] Beneficial Effects

[0020] 1. Compared with traditional rollers, the roller ring combination rollers according to various embodiments of the present invention will not rotate after assembly, which improves the assembly effect, and will not fall off after assembly, which is more convenient for staff to assemble, improves the assembly progress, and is easy to replace when damaged. There is no need to disassemble the axis during replacement, which reduces the difficulty of replacement for staff and improves replacement efficiency.

[0021] 2. Because the four limiting protrusions are fixedly installed on the front and rear sides of the axis, and the two limiting grooves are set on the inner walls of the limiting sleeve A and the limiting sleeve B, and the two limiting protrusions are inserted and connected in the two limiting grooves, the limiting sleeve A and the limiting sleeve B are prevented from rotating after installation, thereby improving the combination effect. In addition, because the two guide shafts are fixedly installed on the right side of the limiting sleeve A, and the limiting sleeve B is slidably connected to the two guide shafts, and the two springs A are installed on the outside of the two guide shafts, and the two springs A are located between the limiting sleeve A and the limiting sleeve B, when the staff squeezes the limiting sleeve inward A and the limiting sleeve B, the length between the limiting sleeve A and the limiting sleeve B becomes shorter, which is convenient for the staff to insert and connect the four fixing blocks into the four fixing grooves. The setting of the two limiting protrusions inserted and connected in the two limiting grooves makes it more convenient for the staff to insert and connect the four fixing blocks into the four fixing grooves, thereby improving the combination efficiency. At the same time, the setting of the four fixing blocks inserted and connected in the four fixing grooves, on the one hand, avoids the limiting sleeve A and the limiting sleeve B from falling off after being combined, and on the other hand, reduces the force on the two limiting protrusions and the two limiting grooves, thereby improving the service life of the present invention.

[0022] 3. Because the two limit blocks are fixedly installed on the outside of the two telescopic blocks, and the two limit blocks are slidably connected to the four limit grooves, the two limit sleeves A and the two limit sleeves B are more stable after being combined. At the same time, the setting of the two limit blocks, on the one hand, plays a better angle positioning role for the roller ring A during combination, which is more convenient for the staff to combine and improves the combination efficiency. On the other hand, it avoids the roller ring A from falling after combination, which is more convenient for the staff to combine and improves the combination progress. At the same time, the two limit sleeves A and the two limit sleeves B play a good limiting role on the roller ring A, which avoids the roller ring A from moving left and right after installation and improves the combination accuracy. Because the two telescopic blocks are slidably installed inside the roller ring A, and the two telescopic blocks are slidably connected to the two guide columns, and the two handles are fixedly installed on the outside of the two limit blocks, when the staff pulls the two handles outward, the two limit blocks are disengaged from the four limit grooves, which is convenient for the staff to replace the roller ring A.

[0023] 4. Because the four anti-drop blocks are fixedly installed on the outside of the eight mounting columns, when the roller ring B contacts the roller ring A, the four anti-drop blocks are inserted and connected to the inside of the roller ring A, which prevents the roller ring B from falling after assembly, making it easier for the staff to assemble and improving the assembly progress. The setting of the two connecting blocks makes the roller ring B and the roller ring A more secure after assembly. At the same time, the two limiting sleeves A and the two limiting sleeves B have a good limiting effect on the roller ring B, preventing the roller ring B from moving left and right after installation, and improving the assembly accuracy. In addition, because the four extrusion rods are slidably installed inside the roller ring A, and the four anti-drop blocks are inserted and connected to the inside of the roller ring A, which prevents the roller ring B from falling off after assembly. The block contacts with the four extrusion rods, and then when the staff presses the four extrusion rods inward, the four anti-drop blocks move inward, which is convenient for the staff to replace the roller ring B. Because the eight mounting plates are fixedly installed on the upper and lower sides of the four extrusion rods, and the eight springs C are fixedly installed on the inner sides of the eight mounting plates, the four extrusion rods are limited, which makes it smoother for the staff to assemble the roller ring B, and improves the assembly efficiency. Under the premise of not disassembling the axis, the present invention is convenient for the staff to replace the roller ring A and the roller ring B, reduces the difficulty of replacement for the staff, and improves the replacement efficiency of the staff.
