The position of the retaining rod 24 is close to the extension body 12, and the position of the retaining rod 24 is away from the extension body 12.

[0041] The movable assembly 2 is arranged at the opening area 3, and the movable assembly 2 comprises a blocking piece 26, a retaining piece 27 and a pulling piece 7. The blocking piece 26 is used for blocking the opening area 3, the retaining piece 27 is used for limiting the position of the blocking piece 26, and the pulling piece 7 is used for releasing the limitation between the retaining piece 27 and the hook 1, so that the retaining piece 27 can be removed.

[0042] The blocking piece 26 is arranged at the opening area 3, and is used for closing the hanging area 4. The blocking piece 26 is composed of a hinged end 21, a body part 28 and a mounting end 29. The hinged end 21 is hinged to the hook 1 through the first hinge rod 20. The hinged end 21 is provided with a notch 30. The width of the notch 30 matches the diameter of the first hinge rod 20. When the blocking piece 26 is mounted into the through groove 19, the opening direction of the notch 30 is consistent with the opening direction of the through groove 19.

[0043] When the blocking piece 26 is mounted, the blocking piece 26 and the second horizontal section 11 are first kept in a horizontal parallel state. Then, the notch 30 is placed in cooperation with the first hinge rod 20. Then, the blocking piece 26 is rotated by 90°.

[0044] The retaining piece 27 is arranged on the mounting end 29. The retaining piece 27 is provided with a retaining end 31. The retaining end 31 is provided with a retaining opening 32. The retaining end 31 is provided with a guide inclined surface 33. The guide inclined surface 33 is used for cooperating with the retaining rod 24. The retaining end 31 can be guided to rotate upwardly by being blocked by the retaining rod 24. Then, the retaining end 31 passes the retaining rod 24. The retaining opening 32 cooperates with the retaining rod 24 to limit.

[0045] The fixing part 5 is provided with the retaining rod 24 and the blocking rod 25. The retaining rod 24 cooperates with the retaining opening 32 to limit. The retaining piece 27 and the mounting end 29 are provided with the spring 34. The retaining piece 27 is provided with a pressing part 35. The second mounting part 36 is provided with a bearing part 37. The pressing part 35 and the bearing part 37 are provided with the positioning column 38. The spring 34 is sleeved on the positioning column 38.

[0046] The spring 34 is used for pushing the retaining piece 27 to rotate, so that the retaining rod 24 is arranged in the retaining opening 32. The mounting end 29 is provided with the second hinge rod 39. The retaining piece 27 is hinged to the mounting end 29 through the second hinge rod 39. The retaining piece 27 is formed with a mounting area 40 in the middle. The mounting end 29 is arranged in the mounting area 40.

[0047] The mounting end 29 is provided with the first mounting part 41 and the second mounting part 36. The first mounting part 41 and the second mounting part 36 form a movable opening 42. The movable opening 42 is provided with a tension spring 43. The mounting end 29 is provided with the positioning rod 44. The mounting end 29 is provided with the positioning hole 45 which cooperates with the positioning rod 44. The middle of the positioning hole 45 is provided with the communication groove 46. The communication groove 46 communicates with the movable opening 42, so as to facilitate the installation of the tension spring 43 and the positioning rod 44. The pulling piece 7 is provided with the pulling rod 47. The retaining piece 27 is provided with the guide groove 48 which accommodates the pulling rod 47. One end of the tension spring 43 is connected with the positioning rod 44. The other end of the tension spring 43 is connected with the pulling rod 47. The pulling piece 7 is provided with the second fixing hole 49 which cooperates with the pulling rod 47.

[0048] The pulling member 7 is used for changing the position of the holding member 27, the middle of the pulling member 7 is hollow to form a movable area 50, and the holding member 27 is arranged in the movable area 50. The pulling member 7 is pulled to push the holding member 27 to make the blocking member 26 close to the blocking rod 25, so that the holding port 32 on the holding member 27 cooperates with the holding rod 24 to limit the position.

[0049] The guide groove 48 is provided with a first plane 51, a guide slope 52 and a second plane 53, the first plane 51 and the second plane 53 are connected through the guide slope 52, and the height of the second plane 53 is greater than that of the first plane 51. When the pulling rod 47 on the first plane 51 reaches the second plane 53, the position of the pulling rod 47 cannot be changed, so only when the pulling rod 47 moves along the guide slope 52, the holding member 27 is forced to move downward, so that the holding member 27 rotates around the second hinge rod 39, and the holding rod 24 is separated from the holding port 32.

[0050] The holding member 27 is provided with an arc-shaped hole 55, the arc-shaped hole 55 is provided with a guide rod 56, the guide rod 56 is arranged on the mounting end 29, and the pulling member 7 is provided with a first strip-shaped hole 57 matched with the guide rod 56. Since the position of the pulling rod 47 is fixed, the guide rod 56 can move relatively in the first strip-shaped hole 57 when the pulling member 7 drives the pulling rod 47 to cooperate with the guide groove 48, that is, the first strip-shaped hole 57 moves, and since the guide rod 56 is also in the arc-shaped hole 55, the arc-shaped hole 55 rotates around the second hinge rod 39 along the guide rod 56.

[0051] The holding member 27 is provided with a second hinge hole 58, and the second hinge rod 39 is arranged in the second hinge hole 58.

[0052] The pulling member 7 is provided with a second strip-shaped hole 59 and a third strip-shaped hole 60, the second hinge rod 39 is arranged in the second strip-shaped hole 59, the mounting end 29 is provided with a limiting rod 61, and the limiting rod 61 is arranged in the third strip-shaped hole 60. The limiting rod 61 is used for limiting the rotated holding member 27, so as to limit the rotating angle of the holding member 27 around the second hinge rod 39.

[0053] The mounting end 29 is further provided with a movable rod 62, the holding member 27 is provided with a square hole 63, the pulling member 7 is provided with a first fixed hole 64 matched with the movable rod 62, and the movable rod 62 is arranged in the square hole 63. The movable rod 62 cooperates with the square hole 63, so as to further improve the stability of the holding member 27 when rotating and improve the connection between the pulling member 7, the blocking member 26 and the holding member 27.

[0054] As Figure 10As shown, in order to better present the force state analysis of the lifting appliance 15, the lifting appliance 15 is in a separated state at this time, but the force state is kept assembled together. When the pulling member 7 is pulled in the direction of F1, the guide slot 48 is kept at the height of the first plane 51 by the pulling rod 47 cooperating with the guide slot 48, so that the retaining member 27 close to the one end of the spring 34 is forced to press down, so that the spring 34 is compressed, and the retaining member 27 rotates around the second hinge rod 39. Thus, the arc-shaped hole 55 and the guide rod 56 cooperate, and the guide rod 56 moves relatively in the arc-shaped hole 55. The retaining end 31 of the retaining member 27 rotates in the direction of F2, so that the retaining hole 32 and the retaining rod 24 are separated, and the retaining member 27 is not limited by the retaining rod 24 at this time, that is, the blocking member 26 can be rotated around the first hinge rod 20. When the blocking member 26 is rotated clockwise by 90°, the notch 30 is arranged downward, and the blocking member 26 can be taken out.

[0055] Since the pulling member 7 needs to be forced to pull out, and in actual use, even if the pulling member 7 is impacted and close to the retaining member 27, the retaining member 27 will not be separated from the retaining rod 24. By arranging the pulling separation, the stability and safety of the whole lifting appliance 15 can be effectively improved, and accidents caused by the opening of the lifting appliance 15 due to accidents can be avoided.

[0056] The above only describes the preferred embodiments of the present application and is not used to limit the present application. Any modification, equivalent replacement and improvement within the spirit and principle of the present application shall be included in the protection scope of the present application.
