When some product workpieces are transported, they need to be limited to a certain extent. The rollers arranged in the roller conveyors are the main components of the conveyor. The existing limiting mechanisms are mostly arranged on the rollers. However, the adjustment of the limiting mechanisms is difficult to operate, and the limit adjustment of the rollers is inconvenient.

[0003] A roller convenient for limiting position is proposed in the patent with publication number CN220501815U, which includes a roller body, a limiting block, a mounting shaft, a connecting sleeve, an adjusting screw, a guide groove, a connecting rod, a buffer spring, a guide bar, a clearance hole, an adjusting block, a clamping block, and an adjusting groove. A guide groove 10 is arranged on the side wall at the end of the roller body 1, and limiting blocks 2 are arranged at both ends of the roller body 1. A guide bar 20 is arranged at the end of the limiting block 2, and the guide bar 20 is installed in the guide groove 10. Under the guiding action of the guide bar 20 and the guide groove 10, the relative movement of the limiting block 2 with the roller body 1 can be stabilized; wherein, the inner end face of the limiting block 2 is an arc surface, and this structure can make the workpiece play a better limiting role when it contacts with the limiting block 2. A connecting sleeve 4 is connected to the outer wall of the limit block 2, and connecting rods 11 are connected to the two ends of the roller body 1. The connecting rod 11 is connected to the mounting shaft 3, and the mounting shaft 3 can be installed on the conveyor frame; a sleeve hole 40 is provided on the connecting sleeve 4, and the sleeve hole 40 is sleeved with the mounting shaft 3. At the same time, a connecting plate 5 is provided inside the connecting sleeve 4, and a clearance hole 50 is provided on the connecting plate 5, and the clearance hole 50 is sleeved with the connecting rod 11; a buffer spring 12 is sleeved on the connecting rod 11, and one end of the buffer spring 12 is in contact with the roller body 1, and the other end is in contact with the connecting plate 5. A connecting hole 30 is provided on the mounting shaft 3, and an adjusting screw 6 is sleeved in the connecting hole 30. A clamping block 61 is provided at the inner end of the adjusting screw 6. A clamping groove 13 is provided at the end of the roller body 1, and the clamping block 61 is embedded in the clamping groove 13 to limit the horizontal movement of the adjusting screw 6.
