Affected by the elastic potential energy of the spring two 19, the connecting plate three 23 is attached to the top end of the star finder 1. At the same time, when the claw two 20 moves downward, it drives the rack two 22 to mesh with the gear 16 inside the fixing bottom plate 21, thereby driving the gear 16 to rotate. The rotating gear 16 meshes with the two groups of racks one 15, so that the two ends of the claw one 14 are driven to move towards the opposite side, thereby limiting the internal star finder 1, and thus fixing the internal star finder 1 more stably. When the rack one 15 moves, it synchronously drives the limiting plate 12 to move. The limiting nail 13 limits the movement of the limiting plate 12, so that the movement of the claw one 14 and the claw two 20 remains stable.
[0023] Please refer to Figure 4, a connection base two 6 is fixedly connected to the bottom end of the fixed base plate 21. A circular groove is formed inside the connection base two 6, and one end of a spring one 7 is fixedly connected inside the circular groove.

When the top end of the first limiting post 8 fits with the bottom end of the first connecting rod 9, affected by the elastic potential energy of the first spring 7, the first limiting post 8 is pushed to move into the first connecting base 5, so as to fix its upper bracket. On the contrary, when it needs to be taken, press the fixing pieces 11 on both sides inward, so that the bottom end of the first connecting rod 9 pushes the first limiting post 8 to fall off the inside of the first connecting base 5, and the upper device can be quickly taken, thus achieving the effect of quickly taking and using. When the star finder 1 needs to be installed, first make the bottom end of the star finder 1 fit with the inner wall of the second claw 20 and press downward. Affected by the elastic potential energy of the second spring 19, the third connecting plate 23 fits with the top end of the star finder 1. At the same time, when the second claw 20 moves downward, it drives the second rack 22 to engage with the gear 16 inside the fixed base plate 21, so as to drive the gear 16 to rotate. The rotating gear 16 engages with the two first racks 15, so that the two first claws 14 at both ends move towards the opposite side, thereby limiting the star finder 1 inside, and thus fixing the star finder 1 inside more stably. When the first rack 15 moves, it synchronously drives the limiting plate 12 to move, and the limiting nail 13 limits the movement of the limiting plate 12, so that the movement of the first claw 14 and the second claw 20 remains stable.
