Rotating rods 708 are rotatably mounted on the left and right sides of the adjusting block 704 and the slider 707, respectively. A fixing spring 709 is sleeved on the outer wall of the slider 706 and located outside the slider 707. A connecting rod 710 is provided at the bottom of the slider 707. A locking block 711 is provided at the lower end of the connecting rod 710. Adjusting grooves 712 are symmetrically opened on the left and right sides of the bottom of the upper connecting seat 701. An adjusting knob 713 is provided on the base surface of the upper connecting seat 701. Locking grooves 714 are symmetrically opened on the left and right sides of the base surface of the lower connecting seat 702.

[0027] The limiting rod 4 is correspondingly and adapted to the limiting hole 6, allowing the limiting rod 4 to enter the interior of the limiting hole 6. The upper connecting seat 701 is fixedly connected to the front and back of the end cover 2, and the lower connecting seat 702 is fixedly connected to the front and back of the housing 1, respectively. The snap-fit ​​block 711 is correspondingly and adapted to the snap-fit ​​groove 714. The adjusting knob 713 is connected to the upper end of the threaded rod 703. By setting the connecting assembly 7 on the motor end cover with the limiting structure, the limiting rod 4 and the limiting hole 6 are connected to the limiting hole 6.

[0028] The working process of this utility model is as follows: When using a motor end cover with a limiting structure, the limiting rod 4 on the end cover 2 is inserted into the limiting hole 6 on the housing 1. The end cover 2 can be limited by the limiting rod 4 and the limiting hole 6. At this time, the locking block 711 enters the inside of the locking groove 714. Then, the adjusting knob 713 is rotated. When the adjusting knob 713 rotates, it drives the threaded rod 703 to rotate. Since the adjusting block 704 is threadedly connected to the threaded rod 703, the threaded rod 703 drives the adjusting block 704 to move when it rotates. When the adjusting block 704 moves, it drives the rotating rod 708 to rotate. When the rotating rod 708 rotates, it drives the slider 707 to slide. When the slider 707 slides, it drives the locking block 711 to lock into the inside of the locking groove 714. The end cover 2 is connected to the housing 1. It can be disassembled by reversing the operation, which makes it easier to disassemble and assemble.
