[0006] The locking mechanism includes two opposite installation grooves in the card-joining groove and slots on the two locking blocks, and the two installation grooves are respectively located in the middle of the two limiting rings. A fan-shaped plug-in block is elastically slidably arranged in each of the installation grooves, and the fan-shaped plug-in block is inserted into the corresponding slot. A sliding rod that passes through the outside of the buckle body is fixedly connected to each of the fan-shaped plug-in blocks. A rotating tube is provided on the surface of the connecting tube, and the rotating tube is connected to one end of the two sliding rods.

[0009] In the above technical solution, preferably, two opposite positioning rods are provided through the surface of the baffle, and one end of each positioning rod is fixedly connected to the surface of the buckle body.

[0010] In the above technical solution, preferably, each of the slots is fixedly connected with a compression spring, and the compression spring is connected to the inner wall of the slot.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0012] The utility model can make the locking block squeeze the corresponding fan-shaped plug-in block and slide it toward the installation groove through the setting of the clamping groove, the limit ring, the locking block and the locking mechanism, until the slot is aligned with the fan-shaped plug-in block, and then automatically insert it into the slot by utilizing the elastic sliding of the fan-shaped plug-in block, so as to plug and lock the locking block, effectively avoiding the random sliding of the locking block, thereby ensuring the locking effect between the two buckle bodies, improving the fixing effect of the two, and avoiding loosening or even falling off between them. When it is necessary to release the fixation between the two buckle bodies, the two rotating tubes are pulled in opposite directions at the same time to make each fan-shaped plug-in block away from the corresponding slot, and the two rotating tubes are rotated in the opposite direction at the same time, so that the locking block can be rotated out of the corresponding clamping groove, and the fixation of the two buckle bodies can be released, and the operation is also more convenient.

[0022] The locking mechanism includes two opposite mounting grooves 95 provided in the snap-fit ​​groove 6 and slots 91 provided on the two locking blocks 8, and the two mounting grooves 95 are respectively located in the middle of the two limiting rings 7, and a fan-shaped plug-in block 94 is elastically and slidably provided in each mounting groove 95, and the fan-shaped plug-in block 94 is plugged into the corresponding slot 91, and when the locking block 8 moves in the corresponding snap-fit ​​groove 6, it can gradually approach the arc surface on the fan-shaped plug-in block 94, so as to push the fan-shaped plug-in block 94 to slide, and each fan-shaped plug-in block 94 is fixedly connected with a sliding rod 92 that penetrates the outside of the buckle body 1, and the surface of the connecting tube 2 is sleeved with a rotating tube 3, and the rotating tube 3 is connected to one end of the two sliding rods 92. Through the setting of the above structure, the stability of the snap-fit ​​between the two buckle bodies 1 can be guaranteed to prevent the two buckle bodies 1 from falling off. , insert the head ends of the two buckle bodies 1 into the corresponding card-joining grooves 6 through the two locking blocks 8 respectively, and rotate to the limit ring 7 for card-joining. At the same time, the locking block 8 will squeeze the corresponding fan-shaped plug block 94 to slide into the installation groove 95, until the slot 91 is aligned with the fan-shaped plug block 94, and then the fan-shaped plug block 94 is automatically inserted into the slot 91 under the elastic sliding of the fan-shaped plug block 94, so that the locking block 8 is plugged and locked, and the random sliding of the locking block 8 is effectively avoided, thereby ensuring the locking effect between the two buckle bodies 1. When it is necessary to release the fixation between the two buckle bodies 1, pull the two rotating tubes 3 in opposite directions at the same time, so that each fan-shaped plug block 94 is away from the corresponding slot 91, and rotate the two rotating tubes 3 in the opposite direction at the same time, so that the locking block 8 is rotated out of the corresponding card-joining groove 6, the fixation of the two buckle bodies 1 can be released, and the operation is also more convenient.
