[0050] The thickened portion 50 is provided with a first hinge rod 51, a second hinge rod 52 and a third hinge rod 35, the first rotating member 13 is mounted on the first hinge rod 51, the second rotating member 14 is mounted on the second hinge rod 52, the third rotating member 15 is mounted on the third hinge rod 35, and the cover plate 3 is mounted on the hinge seat 2 by bolts 53.

[0051] The bearing body 54 is arranged on the hinge seat 2, and the bearing body 54 is arranged in the notch 48. The bearing body 54 is composed of a bottom plate 21 and a frame 55. The frame 55 is arranged on the bottom plate 21, and a bearing chamber 56 is formed in the middle of the frame 55. A symmetrically arranged sliding block 57 is arranged on the bottom surface of the bottom plate 21, and the sliding block 57 cooperates with the sliding groove 11. The frame 55 is provided with a sliding opening 58 that cooperates with the sliding block 57. The four corners of the bottom plate 21 are provided with a sinking part 59, and a hinge column 60 is arranged on the sinking part 59. A release member 61 is arranged on the hinge column 60, and a countersunk hole 62 and a through hole 63 are arranged in the middle of the release member 61. The release member 61 is installed on the hinge column 60 through the first retaining member 36, and the first retaining member 36 is arranged in the countersunk hole 62.

[0052] The release member 61 is composed of a rotating portion 72 and a release portion 71, and the release portion 71 is used to push the limiting rod 44 out of the limiting opening 42. The countersunk hole 62 is provided with a strip groove 73 for placing the first pin 38, and the sinking portion 59 is provided with a mounting hole 74 for installing the second pin 39. The hinge seat is also provided with a mounting hole 74 and a strip groove 73, so that the second retaining member 34 can limit the angle of the third rotating member 15.

[0053] A plurality of elastic arms 64 are provided on the hinge column 60, and undercut portions 65 are provided on the elastic arms 64. The elastic arms 64 are arranged in the through hole 63, and the hinge column 60 is arranged in the countersunk hole 62. The release member 61 can be restricted on the hinge column 60 by the undercut portions 65, and will not be separated from the hinge column 60, but can rotate around the hinge column 60, but can be reset by the first retaining member 36 after the rotation.

[0054] A recessed opening 32 is provided on the bottom plate 21 , a first arc surface 66 is provided at one end of the recessed opening 32 , and a second arc surface 67 is provided at the other end. The arc angle of the first arc surface 66 is smaller than the arc angle of the second arc surface 67 , and the sixth rotating arm 30 contacts the first arc surface 66 .

[0055] The height of the sinking portion 59 matches the height of the first extension portion 19 , the second extension portion 26 and the third extension portion 31 , so that the contact member on the sinking portion 59 does not push the first rotating member 13 and the second rotating member 14 , but can only push the limiting rod 44 on the third rotating member 15 .

[0056] The movable seat 5 is arranged on the positioning block 6, and the movable seat 5 is composed of a triangular block 68 and a symmetrical pushing block 69.

[0057] An adjusting member 22 is provided on the movable rod 70 . The adjusting member 22 can be installed on the movable rod 70 by means of threads, so as to change the elastic force of the spring 7 .

[0058] The friction force between the limiting rod 44 and the limiting opening 42 is N1, the torsion force of the first retaining member 36 is N2, N2>N1, and the torsion force of the second retaining member 34 is N3, N1>N3. The first retaining member 36 can push out the limiting rod 44 in the recessed opening 32 when being driven by the bearing member 4, but the second retaining member 34 cannot push out the limiting rod 44 from the recessed opening 32 under its own elastic force. The second retaining member 34 can only make the sixth rotating arm 30 of the third rotating member 15 contact with the blocking block 40, and the first retaining member 36 can push out the limiting rod 44 from the recessed opening 32.

[0059] When installing the supporting member 4, align the sliding block 57 on the supporting member 4 with the sliding groove 11 and then push it in, so that the supporting member 4 first pushes the sixth rotating arm 30 to rotate, and finally the sixth rotating arm 30 enters the recessed opening 32 to limit the position, so that the position of the supporting member 4 can be limited by the third rotating member 15.

[0060] When the carrier 4 needs to be taken out, the carrier 4 is first pushed toward the moving seat 5, and then the carrier 4 is kept to push the first rotating arm 17, so that the second rotating arm 18 pushes the third rotating arm 24, so that the second rotating member 14 rotates, and the fourth rotating arm 25 is kept to push the fifth rotating arm 29, and finally the sixth rotating arm 30 is separated from the contact with the blocking block 40, so that the limiting rod 44 enters the limiting opening 42. After the sixth rotating arm 30 passes over the recessed opening 32, the release member 61 will push out the limiting rod 44 in the limiting opening 42, so that the next carrier 4 can be directly inserted into the limiting position.

[0061] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
