[0043] The fixed column 202f is used to provide limiting support for the limiting plate 202g, and the limiting plate 202g can rotate on the surface of the fixed column 202f.

[0044] Specifically, the adjusting member 202 further includes a limit block 202h and a positioning block 202i. The limit block 202h is fixed to one side of the limit plate 202g, and the positioning block 202i is fixed to one side of the positioning plate 202e.

[0045] The limiting block 202h is located on one side of the positioning block 202i, and can limit the rotation angle of the limiting plate 202g to keep the limiting plate 202g stable.

The telescopic spring 202k can cause the limit plate 202g to rotate. The telescopic spring 202k is currently in a stretched state. Through the pulling force of the telescopic spring 202k, the limit block 202h can be moved to the side of the positioning block 202i.

[0048] Example 3

[0049] Reference Figure 2 to Figure 6 , which is the third embodiment of the utility model, and this embodiment is based on the first two embodiments.

[0050] Specifically, the adjusting member 202 further includes an adjusting rod 2021 and a limiting block 202m. The adjusting rod 2021 is fixed to one side of the limiting plate 202g, and the limiting block 202m is fixed to one side of the limiting plate 202g.

[0051] The adjusting rod 2021 can drive the limiting plate 202g, so that the limiting plate 202g can drive the limiting block 202m to rotate, and the limiting block 202m is used to limit the position of the limiting plate 202g.

[0052] Specifically, the moving member 203 includes a support rod 203a and a limiting gear 203b. The support rod 203a is fixed to one side of the positioning plate 202e, and the limiting gear 203b is rotatably connected to the surface of the support rod 203a.

[0053] The support rod 203a is used to fix the position of the limit gear 203b, and the limit gear 203b can engage with the limit block 202m, so that the limit plate 202g can be controlled to prevent rotation through the limit block 202h and the telescopic spring 202k. In this way, the limit plate 202g can limit the position of the limit gear 203b through the limit block 202m, ensuring that the limit gear 203b will not move, and the position of the movable sleeve 202c can be fixed.

[0054] Specifically, the moving member 203 further includes a rack 203c and a contact plate 203d. The rack 203c is fixed to the surface of the support column 202a, and the contact plate 203d is fixed to the surface of the moving sleeve 202c.

[0055] The rack 203c is meshed with the limit gear 203b, and the limit plate 202g can be moved by adjusting the rod 202l to release the fixation of the limit gear 203b by the limit block 202m. At this time, the positioning plate 202e can be pushed to move the movable sleeve 202c to adjust the moving stroke of the movable gear 104.

[0056] When in use, when it is necessary to adjust the stroke of the tubular motor, first pull the adjusting rod 202l to release the limit of the limit plate 202g. When the limit plate 202g is pulled by the adjusting rod 202l, the telescopic spring 202k is in a stretched state, and then the positioning plate 202e is pushed to move. When the positioning plate 202e moves, the limit gear 203b and the rack 203c are engaged with each other, so that the positioning plate 202e can move quickly, and the positioning plate 202e can drive the moving sleeve 202c to move, so as to adjust the stroke distance between the moving gear 104 and the contact plate 203d. After adjusting to a certain distance, the adjusting rod 202l can be loosened. At this time, the telescopic spring 202k will drive the limit gear 203b to move. The positioning plate 202g rotates in the direction of the telescopic spring 202k, so that the limiting block 202m on one side of the limiting plate 202g will engage with the limiting gear 203b, and through the cooperation of the limiting block 202h and the positioning block 202i, the position of the limiting plate 202g can be limited, so that the limiting plate 202g can fix the position of the limiting gear 203b through the limiting block 202m, thereby ensuring that the moving sleeve 202c will not be offset, thereby shortening the travel distance between the moving gear 104 and the contact plate 203d, thereby quickly adjusting the travel of the tubular motor, and when it is necessary to finely adjust the travel, the rotating rod 103 can be rotated to finely adjust the position of the moving gear 104.
