When the transmission rod 710 rotates, the gear 709 also rotates, thereby driving the movement of the rack 1 706 and the rack 2 707, and the two slide rails 713 can provide stable support and limit for the movement of the rack 2 707.

[0030] Specifically, Figure 3-5 As shown, the top of the connecting plate 701 is fixedly connected to two locking plates 1 702 and two locking plates 2 703, one end of the two racks 1 706 and the two racks 2 707 are fixedly connected to locking blocks 705, the middle parts of the two locking plates 1 702 and the two locking plates 2 703 are provided with locking grooves 712, the tops of the two locking plates 1 702 and the two locking plates 2 703 pass through the bottom plate 708, one end of the two locking blocks 705 passes through two of the locking grooves 712, one end of the other two locking blocks 705 passes through the other two locking grooves 712, and the bottom end of the connecting plate 701 is fixedly connected to the X-ray camera body 6.

The iron rod 413 falls on the buffer plate 407, and the buffer plate 407 drives two buffer springs 408 to reduce the vibration of the buffer plate 407. Then, the buffer plate 407 is pressed down by the weight of the iron rod 413, and the buffer plate 407 slowly descends. The buffer plate 407 drives the trigger rod 417 to squeeze the press-type alarm 409, thereby reminding the user that the current transmission arm 9 or the connecting arm 11 is offset. , the user can adjust its position to avoid detection errors caused by offset when the X-ray camera body 6 is shooting. When the user needs to install the X-ray camera body 6, the user can align the connecting plate 701 with the bottom plate 708, and then push the connecting plate 701. The two locking plates 1 702 and the two locking plates 2 703 at the top of the connecting plate 701 all penetrate the bottom plate 708.

The locking blocks 705 at one end of the two racks 1 706 and the locking blocks 705 at one end of the two racks 2 707 are respectively inserted into the four locking grooves 712.
