No matter the first support rod 11 rotates relative to the joint seat 10 or the second support rod 12 rotates relative to the joint seat 10, the first gear 21 and the second gear 22 will be driven to rotate during the rotation, and the rotational motion will be transmitted to the other rod, so that the first support rod 11 and the second support rod 12 can rotate synchronously relative to the joint seat 10. When folding or unfolding, only the first support rod 11 or the second support rod 12 needs to be applied with force to make the second support rod 12 or the first support rod 11 follow the action. The folding or unfolding operation is very convenient and quick. Installing it on the game fence also makes the game fence flexible to fold and not get stuck.
[0032] like Figure 2 and Figure 5 As shown, the joint seat 10 is also provided with a locking assembly 3 capable of locking the first support rod 11 and the second support rod 12 in the unfolded position.
[0033] like Figure 4 As shown, the first transmission tooth portion 23 and the second transmission tooth portion 24 are both sector gears.
[0034] like Figure 5 , Figure 7 , Fig. 9 and Fig.11As shown, the locking assembly 3 includes a first locking position 31 at the end of the first support rod 11 and a second locking position 32 at the end of the second support rod 12, a first locking shaft 33 that can be engaged with or disengaged from the first locking position 31 is provided on the joint seat 10, and a second locking shaft 34 that can be engaged with or disengaged from the second locking position 32 is also provided on the joint seat 10, and an operating member 35 that can simultaneously drive the first locking shaft 33 to disengage from the first locking position 31 and the second locking shaft 34 to disengage from the second locking position 32 is also provided on the joint seat 10, and a reset spring 30 that can push the operating member 35 to reset is also provided between the operating member 35 and the joint seat 10. When the first support rod 11 and the second support rod 12 need to be folded with each other, the operating member 35 is pressed, and the operating member 35 drives the first locking shaft 33 to disengage from the first locking position 31, and drives the second locking shaft 34 to disengage from the second locking position 32 at the same time, and the first support rod 11 and the second support rod 12 are unlocked at the same time by only pressing the operating member 35, and the operation is very convenient and quick.
[0035] like Figure 5 , Figure 7 , Fig. 9 and Fig.11 As shown, the first locking shaft 33 cooperates with the first locking position 31 and engages with or disengages from the first locking position 31 when it moves laterally relative to the joint seat 10, and the second locking shaft 34 cooperates with the second locking position 32 and engages with or disengages from the second locking position 32 when it moves laterally relative to the joint seat 10.

The first locking position 31 is a first notch provided at the end of the first support rod 11, and the second locking position 32 is a second notch provided at the end of the second support rod 12. When the first support rod 11 and the second support rod 12 move to the folding position, the first protruding shaft abuts in the first notch, and the second protruding shaft abuts in the second notch. When the first support rod 11 and the second support rod 12 are folded to the folding position, the first protruding shaft abuts in the first notch, and the second protruding shaft abuts in the second notch, so that the rotation angle of the first support rod 11 and the second support rod 12 can be limited.
[0039] like Fig.11 As shown, the end of the first support rod 11 is also provided with a first arc surface 13 that can push the first locking shaft 33 to move laterally when it rotates from the folded position to the unfolded position relative to the joint seat 10, and the end of the second support rod 12 is also provided with a second arc surface 14 that can push the second locking shaft 34 to move laterally when it rotates from the folded position to the unfolded position relative to the joint seat 10. When the first support rod 11 and the second support rod 12 rotate relative to each other and unfold, the first arc surface 13 can push the first locking shaft 33 to move laterally, and the second arc surface 14 can push the second locking shaft 34 to move laterally. During the lateral movement of the first locking shaft 33 and the second locking shaft 34, the operating block is pushed to move through the left oblique groove 36 and the right oblique groove 37, and the spring 30 is compressed. Once the first support rod 11 and the second support rod 12 reach the unfolded position, the spring 30 is reset, the operating block moves upward, and the groove walls of the left oblique groove 36 and the right oblique groove 37 push the first locking shaft 33 and the second locking shaft 34 to move laterally, so that the first locking shaft 33 is engaged with the first locking position 31 again, and the second locking shaft 34 is engaged with the second locking position 32 again.
[0040] The first support rod 11 and the second support rod 12 of the joint structure of this embodiment are linked and rotated synchronously through the transmission assembly 2 during the folding or unfolding process, so that during the folding or unfolding operation, only one of the first support rod 11 and the second support rod 12 needs to be applied with force to achieve folding or unfolding, and the folding or unfolding action is performed synchronously, smoothly and without jamming, and is suitable for application in other children's products such as game fences.
