[0034] Detailed explanation of usage: When using an AC servo driver to control a servo motor, connect the AC power line to the R, S, and T terminals of the driver, connect the power line of the AC servo motor to the U, V, and W terminals of the driver, and then connect the encoder connection line of the AC servo motor to the CN2 port of the driver, and then connect the PLC to the CN1 port of the driver. The driver receives the I / O control signal from the PLC to control the servo. During operation, the encoder feeds back the operating status of the servo motor to the driver. However, this operation will cause the following problems: When performing internal maintenance, the cover frame 5 needs to be disassembled. To disassemble the cover frame 5, tools are needed to operate multiple screws, which makes the disassembly and assembly of the cover frame 5 time-consuming and labor-intensive, and further leads to the problem of low maintenance efficiency. By setting the adjustment structure 6, the cover frame 5 is first disassembled, and the two moving blocks 602 are moved in a direction close to each other. During this process, the moving block 602 slides along the adjustment slot 601, and the spring 603 is in a compressed state. The moving block 602 drives the limit rod 606 and the limit block 607 to slide along the limit frame 608 until the limit frame 608 releases the limit on the limit block 607, and then the cover frame 5 is operated to move away. The cover frame 5 moves in the direction away from the bottom shell 4, and the cover frame 5 drives the limit rod 606 and the limit block 607 to slide away from the limit frame 608 through the moving block 602. At this time, the interior of the driver can be maintained. After the maintenance is completed, the cover frame 5 is operated to approach the bottom shell 4 to make the limit rod 606 and the limit block 607 slide into the limit frame 608. After the limit rod 606 and the limit block 607 completely slide into the limit frame 608, the moving block 602 is released. The two moving blocks 602 move away from each other under the action of the elastic force of the spring 603.

[0035] The auxiliary structure 7 is provided, and after the wiring operation is completed, the connecting wire is placed in the auxiliary groove 76 on the support plate 72, and the auxiliary rod 73 is rotated. The auxiliary rod 73 drives the clamping plate 74 to move in the direction close to the support plate 72 by means of the thread, and the clamping plate 74 slides along the round rod 75 until the clamping plate 74 cooperates with the support plate 72 to clamp and limit the connecting wire. Among them, the auxiliary groove 76 makes the supporting plate 72 and the clamping plate 74 have a better limiting effect on the connecting wire, thereby realizing that the supporting plate 72 and the clamping plate 74 are used to clamp and limit the connecting wire, thereby improving the connection stability between the connecting wire and the terminal on the servo driver, and preventing the connecting wire from being accidentally touched, resulting in poor contact.
