[0029] In this embodiment, the rotating drum 108 is mounted on the outer wall of the column 107 and can be rotated according to the angle required for installation. At the same time, the connecting lug 109 is used to install and fix the male lock unit 104 and the female lock unit 105, so that the angle of the male lock unit 104 and the female lock unit 105 can be adjusted by rotating the rotating drum 108.

[0030] Furthermore, each group of the male lock unit 104 includes a lock plate 110, a lock piece 111, a first bolt 112 and a first nut 113. The lock piece 111 is fixedly connected to the lock plate 110 and is located on one side of the lock plate 110. There are multiple groups of the first bolts 112. Each group of the first bolts 112 is respectively fixedly connected to the lock plate 110 and is respectively located on one side of the lock plate 110. There are multiple groups of the first nuts 113. Each group of the first nuts 113 is respectively threadedly connected to the corresponding first bolt 112 and is sleeved on the outer wall of the corresponding first bolt 112.

[0031] In this embodiment, the locking plate 110 is fixed to one side of the connecting member by the first bolt 112 and the first nut 113, and the locking member 111 is supported and fixed by the locking plate 110. The locking member 111 can be directly embedded in the female lock unit 105 and can also be directly detached from the female lock unit 105.

[0032] Furthermore, each group of the female lock unit 105 includes a lock chamber, a second bolt 114, a second nut 115, a limit piece and a return spring 116.

The number of the return springs 116 is two groups, and each group of the return springs 116 is respectively sleeved on the outer wall of the limit piece, and each group of the return springs 116 is respectively located between the limit piece and the lock chamber.

[0033] In this embodiment, the second bolt 114 and the second nut 115 fix the lock magazine to one side of the connecting member, and the two groups of limit members are embedded in the interior of the lock magazine. When the male lock unit 104 is inserted into the female lock unit 105, the two groups of limit members are pushed to both sides, and at the same time, each group of limit members squeezes and compresses the return spring 116 until the male lock unit 104 is inserted between the two groups of limit members. At the same time, the middle part of the lock member 111 is a concave structure. Therefore, after the lock member 111 is inserted, the limit member is quickly reset by the return spring 116 to clamp and limit the lock member 111. When disassembling, the limit member is also squeezed to both sides until the lock member 111 is pulled out.

[0034] Furthermore, each group of the limiting parts includes a triangular locking block 117, a guide rod 118, a locking rod 119 and a limiting ring 120.

Each group of sliding covers 123 is respectively arranged at the two ends of the warehouse body 121, and each group of sliding covers 123 is respectively embedded in the corresponding slide groove 125.

[0037] In this embodiment, the magazine body 121 installs the locking rod 119 and the guide rod 118, and the guide rod 118 is embedded in the corresponding guide groove 124. When the male lock unit 104 and the female lock unit 105 are locked, the sliding cover 123 moves along the sliding groove 125 until the sliding cover 123 is placed on the upper end of the locking rod 119, thereby limiting the locking rod 119 to prevent the locking member 111 from falling off during use. The fixed cover 122 prevents the sliding cover 123 from being accidentally touched during the limiting process, thereby preventing the locking member 111 from detaching.

[0038] Furthermore, the lock magazine also includes a dial block 126, a first magnet 127, a second magnet 128 and a magnetic block 129, the number of the dial blocks 126 being two groups, each group of the dial blocks 126 being fixedly connected to the corresponding sliding cover 123 and being respectively located on one side of the corresponding sliding cover 123, the number of the magnetic blocks 129 being multiple groups, each group of the magnetic blocks 129 being fixedly connected to the corresponding sliding cover 123 and being respectively located on both sides of the corresponding sliding cover 123, the number of the first magnet 127 being multiple groups, each group of the first magnet 127 being fixedly connected to the corresponding magnetic block 129 and being respectively embedded in one side of the corresponding magnetic block 129, the number of the second magnet 128 being multiple groups, each group of the second magnet 128 being fixedly connected to the corresponding fixed cover 122 and being respectively embedded in one side of the corresponding fixed cover 122, and the corresponding first magnet 127 and the second magnet 128 being adapted to each other.

[0039] In this embodiment, the shift block 126 facilitates the movement control of the sliding cover 123, and at the same time the magnetic block 129 installs and fixes the first magnet 127, and the second magnet 128 is embedded in one side of the fixed cover 122.
