At the same time, the electric push rod 41 can be buckled into the triangular insertion slot 312 opened on the right side of the installation side plate 311 of the control box body 31 through the triangular insertion plate 43 on the left side of the inclined installation plate 42, and then the knob 318 on the rear side of the installation side plate 311 is rotated, so that the threaded rod 314 in the drive cabin 313 is rotated, and the movable plate 315 is connected with the threaded rod 314 by threads, so that the two fixed insertion plates 316 are buckled with the two fixed slots 44 opened on the rear side of the triangular insertion plate 43 after penetrating through the two butt joints 317, so that the electric push rod 41 and the control box body 31 form an integral whole. When disassembling, the fixed insertion plate 316 is separated from the fixed slot 44 by reversing the knob 318, so that the inclined installation plate 42 and the electric push rod 41 are disassembled. Before the electric push rod 41 is installed with the control box body 31, the output end of the electric push rod 41 can penetrate through the vertical frame 5 and be aligned with the threaded hole 61 by using the locking threaded hole 412 on the top of the door-shaped butt joint block 411, and then the locking knob 63 is rotated to rotate the locking screw 62 threadedly installed in the inner circle of the threaded hole 61 downward, until the threaded connection with the locking threaded hole 412 on the top of the door-shaped butt joint block 411 is completed, and the door-shaped butt joint block 411 is fixed. When disassembling the overall electric push rod 41, the locking screw 62 is reversed by reversing the locking knob 63, so that the door-shaped butt joint block 411 is separated from the locking threaded hole 412, so that the electric push rod 41 is conveniently disassembled and repaired.

[0034] The above has been described in detail, but some modifications or improvements can be made on the basis of the present application, which is obvious to those skilled in the art. Therefore, the modifications or improvements without departing from the spirit of the present application are within the scope of the present application.
