For example, detachable connection can be selected according to the needs of screw connection, bolt connection, threaded connection, snap connection, mortise and tenon connection, Velcro connection and other methods. The various technical features in the creation of the utility model can be combined interactively without conflicting with each other.

[0026] Please refer to Figure 1-Figure 5 , a cylinder limiting device, used for positioning the rotation position of the gear plate 7, comprises a driving component 2, a swinging component 5, a clamping component 3, a limiting plate 4 and a mounting plate 1 fixedly arranged on the gear plate 7, the limiting plate 4 is provided with a positioning groove 41, the driving component 2 and the swinging component 5 are both mounted on the mounting plate 1, the output end of the driving component 2 is movably connected with the swinging plate 51 of the swinging component 5, the clamping component 3 is mounted on the swinging component 5, the driving component 2 is used to drive the clamping component 3 to swing so that the clamping component 3 is clamped into the positioning groove 41 of the limiting plate 4 or disengaged from the positioning groove 41 of the limiting plate 4, thereby fixing or loosening the gear plate 7.

[0027] Furthermore, the swing assembly 5 includes a swing plate 51 and a swing mounting shaft 52, the swing mounting shaft 52 is fixedly mounted on the mounting plate 1, the swing plate 51 is rotatably mounted on the swing mounting shaft 52, and the clamping assembly 3 is arranged at one end of the swing plate 51 away from the swing mounting shaft 52, which can prevent the swing plate 51 and the gear plate 7 from interfering with each other. The swing plate 51 is driven by the driving assembly 2 to swing back and forth along the direction of the rotating axis of the swing mounting plate 1, thereby driving the clamping assembly 3 to engage or disengage with the limit plate 4.

[0028] Furthermore, the driving assembly 2 is a cylinder driving assembly 2, which includes a driving cylinder 21 and a cylinder mounting shaft 23. The driving cylinder 21 is rotatably mounted on the cylinder mounting shaft 23 through a cylinder mounting seat. The output shaft of the driving cylinder 21 is movably connected to the swing plate 51 and can drive the swing plate 51 to swing. The output shaft of the driving cylinder 21 is connected to an end of the swing plate 51 away from the swing mounting shaft 52. The output shaft of the driving cylinder 21 is provided with a fisheye joint 22. A fisheye joint mounting groove 53 is provided on the swing plate 51. The free end of the fisheye joint 22 extends into the fisheye joint mounting groove 53 and is rotatably mounted in the fisheye joint mounting groove 53 through the fisheye joint 22 rotating shaft. A mounting hole for mounting the fisheye joint 22 rotating shaft is provided on the swing plate 51.

[0029] Among them, the force analysis of the straight-in and straight-out structure of the driving cylinder 21 is carried out. The tangential force received at the radial bearing will be converted into pressure along the direction of the cylinder. This force is along the axial direction of the mounting cylinder and acts on the cylinder mounting shaft 23, meeting the use conditions of the cylinder, while part of the force will be perpendicular to the direction of the cylinder mounting shaft 23, that is, part of the radial force is generated, which will cause damage to the cylinder. The combination of the swing mounting shaft 52 and the swing plate 51 can increase the rigidity and stability of the driving cylinder 21, thereby reducing the deformation that may occur in the cylinder during operation and reducing the influence of the radial force. Therefore, the radial force can be effectively transmitted to the overall structure through the swing assembly 5, thereby reducing the radial force received by the driving cylinder 21, so that the driving cylinder 21 is only subjected to the force along the axial direction of the driving cylinder 21.

[0030] Further, the clamping assembly 3 includes a connecting member and a clamping portion rotatably connected to one end of the connecting member, the connecting member is a double elbow joint 31, the clamping portion is a radial joint bearing 33, the double elbow joint 31 is fixedly mounted on the swing plate 51, the radial joint bearing 33 is arranged at the other end of the double elbow joint 31, the double elbow joint 31 is provided with a bearing mounting groove, the radial joint bearing 33 is installed in the bearing mounting groove through the central axis 32, and the radial joint bearing 33 is used to be clamped into the positioning groove 41 of the limiting plate 4 to realize the mutual positioning of the clamping assembly 3 and the limiting plate 4. The middle part of the positioning groove 41 is the clamping groove, and the two sides of the positioning groove 41 are gentle avoidance parts so that the radial joint bearing 31 can enter the clamping groove. The double elbow joint 31 is provided with a central shaft 32 mounting hole, the central shaft 32 passes through the central shaft 32 mounting hole, and a bottom cover and a pressure cover 34 are respectively provided at both ends of the central shaft 32, and the pressure cover 34 is used to lock the central shaft 32 on the double elbow joint 31.

[0031] The central shaft 32 and the radial spherical bearing 33 can be locked on the double elbow joint 31 by a pressure cap 34, or can be directly welded on the double elbow joint 31. In this embodiment, the central shaft 32 and the radial spherical bearing 33 are locked on the double elbow joint 31 by a pressure cap 34, which is convenient for disassembly and maintenance. When maintenance or replacement of parts is required, the central shaft 32 and the radial spherical bearing 33 can be easily disassembled by simply loosening the pressure cap 34, which is convenient for maintenance and maintenance.

[0032] It should be noted that the connecting member may also be a connecting rod, one end of which is fixedly mounted on the swing plate 51 , and the other end of which is rotatably connected to the radial spherical bearing 33 via a rotating shaft.

[0033] Furthermore, the limit plate 4 is fixed on the gear plate 7 by screws, and an arc-shaped slot 42 is opened on the limit plate 4. The arc-shaped slot 42 is arranged cocentrically with the gear plate 7, which can help position the limit plate 4 and ensure that the limit plate 4 will not deviate from the position, thereby reducing the error.

When the winding shaft moves to the desired position, that is, the gear plate 7 rotates to the desired angle, the driving cylinder 21 extends, and drives the double elbow joint 31 to extend and swing, so that the double elbow joint 31 is clamped into the positioning groove 41 to fix the position of the gear plate 7, thereby fixing the position of the winding shaft; when the winding shaft is moved again, the driving cylinder 21 is retracted, and the double elbow joint 31 will also retract accordingly, and the double elbow joint 31 will disengage from the positioning groove 41.
