[0026] Furthermore, a connecting ring 9 is fixedly installed on the outer side of the two groups of mounting grooves of the connecting pipe 4, and a thread is provided on the outer surface of the connecting ring 9. A protective cover 6 is movably installed on the outer surface of the connecting ring 9. The protective cover 6 is used to protect the telescopic pin 112 to keep it clean and in good working condition. In addition, the protective cover 6 can also reduce the risk of accidental impact or damage to the telescopic pin 112 and extend its service life.

[0027] Furthermore, multiple groups of operating rods 911 are fixedly mounted on the outer surface of the connecting ring 9, and one end of the multiple groups of operating rods 911 is in an arc shape. The introduction of the operating rods 911 provides a more convenient and comfortable operation method for the operator. Since one end of the operating rod is in an arc shape, this design is more ergonomic, allowing the operator to save effort and feel more comfortable when rotating the connecting ring 9 or performing other related operations. This can not only improve the operating efficiency, but also reduce the fatigue of the operator.

[0028] Furthermore, one side of the two sets of connecting rods 111 is provided with abutment grooves 113. The design of the abutment grooves 113 provided on one side of the two sets of connecting rods 111 enables the paper feed roller to be more accurately positioned and aligned with other components during the assembly process. The abutment grooves 113 provide a clear positioning point, which helps the operator to complete the assembly quickly and accurately. This not only improves the assembly efficiency, but also reduces the risk of failure caused by improper assembly.

[0029] Furthermore, an abutment rod 512 is fixedly installed on the inner wall of one side of the connection cover 5. The design of the abutment rod 512 fixedly installed on the inner wall of one side of the connection cover 5 enhances the connection stability between the paper feed roller and the connection tube 4.

[0032] Working principle: Both sides of the paper feed roller body 1 are connected with connecting rods 111, and springs and telescopic pins 112 are arranged on the connecting rods 111. During the assembly process, the connecting rods 111 are first inserted through the inner wall of the bearing ring 3. As the connecting rods 111 move, the springs are compressed. When the connecting rods 111 move to the correct position, the elastic force of the springs pushes the telescopic pins 112 to pop outwards and pass through the mounting grooves on the outer surface of the connecting tube 4, thereby achieving the preliminary fixation of the paper feed roller body 1 and the connecting tube 4.

[0033] A thread is provided in the connection groove 8 on one side of the connection tube 4, which cooperates with the clamping ring 511. One end of the clamping ring 511 is connected to the connection cover 5. By rotating the connection cover 5, the clamping ring 511 can move along the connection groove 8 under the action of the thread until it is tightly connected with the connection tube 4, so as to achieve complete fixation of the paper feed roller and the mounting bearing seat 2.
