[0029] In actual application, by setting a limit rod 33, the cover 2 on the shell 1 is pulled to one side. When the cover 2 moves, it drives the sliding bars 31 on both sides to move in the corresponding travel grooves 32, which helps to fix the moving path of the cover 2. The cover 2 drives the connecting plate 34 to move synchronously, and the connecting plate 34 drives the limit rod 33 to move synchronously in the limit hole of the shell 1. The cover 2 is limited under the action of the retaining ring of the limit rod 33 and the limit hole of the shell 1.

[0030] Example 2: A servo drive that is easy to maintain, which is different from Examples 1 and 3 in that: Figure 3 As shown, the outer wall of the limit rod 33 is slidably connected to the inner wall of the limit hole, the side wall of the connecting plate 34 is fixedly connected to the side wall of the cover plate 2, one end of the fixing rod 35 is fixedly connected to the inner wall of the top surface of the shell 1, one end of the first telescopic spring 37 is fixedly connected to the inner wall of the top surface of the shell 1, and the other end of the first telescopic spring 37 is fixedly connected to the upper surface of the sliding sleeve 36.

[0034] Working principle: when maintaining the servo driver, first press the moving bars 39 on both sides of the housing 1 to one side. At this time, the moving bars 39 on both sides drive the corresponding sliding sleeves 36 to move on the fixed rod 35. At the same time, the sliding sleeves 36 stretch the first telescopic springs 37 on the fixed rod 35. At the same time, the moving bars 39 on both sides drive the corresponding positioning rods 38 to move synchronously, and then the moving bars 39 move the corresponding positioning rods 38 out of the positioning holes of the sliding bars 31 on both sides. At this time, pull the cover plate 2 on the housing 1 to one side, and the cover plate 2 moves while driving the two The sliding bar 31 on the side moves in the corresponding stroke groove 32, the cover 2 drives the connecting plate 34 to move synchronously, and the connecting plate 34 drives the limiting rod 33 to move synchronously in the limiting hole of the shell 1.
