Limiting assembly 4 is fixed on the other end of second movable block 22.

[0029] When the loading platform 31 needs to be rotated in actual use, the electromagnet 26 is powered off, so that the thrust of the magnet block 29 is unloaded, so that the first spring 28 can pull the second movable block 22 back, so that the limiting assembly 4 can be separated from the limit hole 33, and the limiting is released at this time. Directly rotate the loading platform 31, when locking is needed, the electromagnet 26 is powered on, a thrust is generated on the magnet block 29, so that the two first movable blocks 24 are close to each other, so as to push the second movable block 22 to move, and then the limiting assembly 4 is directly inserted into the limit hole 33 for locking. Compared with the previous manual locking, the operation is convenient and fast.

[0030] Further, mounting holes are formed in the top corners of base 1, and the mounting holes are arranged to facilitate the mounting and fixing of the device as a whole.

[0031] Further, a first limiting rod 27 is fixed on one end of second movable block 22 corresponding to first spring 28, the first limiting rod 27 is swingly penetrated in the side wall of fixed box 21, and the first limiting rod 27 can limit the movement track of second movable block 22, so as to ensure the high movement stability of second movable block 22.

[0032] It is worth mentioning that the second limiting rod 23 is fixed on the two sides of one side wall of first movable block 24, the second limiting rod 23 is swingly penetrated in the fixed plate 25, and the second limiting rod 23 is arranged to limit the movement track of first movable block 24, so as to ensure the movement stability of first movable block 24.

[0033] For example Fig. 2and 3 The limiting assembly 4 includes a limiting column 41 fixedly connected with the second movable block 22, a cavity is formed at the end of the limiting column 41, a movable rod 42 is movably penetrated through the end of the limiting column 41, a conical block 43 is fixedly connected to the inner end of the movable rod 42, wedge-shaped blocks 45 are attached to the two side walls of the conical block 43, and abutting rods 46 are fixedly connected to the side walls of the wedge-shaped blocks 45 and movably penetrated through the limiting column 41.

[0034] In actual use, after the limiting column 41 is inserted into the limiting hole 33, the movable rod 42 abuts against the inner wall of the limiting hole 33, thereby driving the conical block 43 to push the wedge-shaped blocks 45 to move, so that the abutting rods 46 on the wedge-shaped blocks 45 can move outward, thereby abutting against the inner walls of the two sides of the limiting hole 33, so as to realize automatic locking.

When locking is needed, the electromagnet 26 is powered on to generate a pushing force on the magnet block 29, so that the two first movable blocks 24 move close to each other, thereby pushing the second movable block 22 to move, and further making the limiting assembly 4 directly inserted into the limiting hole 33 for locking. Compared with the previous manual locking, the operation is convenient and fast. After the limiting column 41 is inserted into the limiting hole 33, the movable rod 42 abuts against the inner wall of the limiting hole 33, thereby driving the conical block 43 to push the wedge-shaped blocks 45 to move, so that the abutting rods 46 on the wedge-shaped blocks 45 can move outward, thereby abutting against the inner walls of the two sides of the limiting hole 33, so as to realize automatic locking. Even if wear occurs, automatic locking can also be realized, thereby improving the stability after locking and the use effect, and avoiding the occurrence of wear and shaking.
