Through the guiding effect of the inclined surface, the clamping block 8 is squeezed to move inward, driving the moving block 7 to squeeze the spring 9 to contract and deform to generate elastic force. After the elastic force of the spring 9 reacts on the moving block 7, an outward thrust of the clamping block 8 is generated.

The plurality of reinforcing ribs 4 are evenly distributed in a ring shape along the surface of the cross bar 2. A reinforcing rod 16 is fixedly connected between the bottom end inside the cross bar 2 and the side wall of the vertical bar 1.

[0031] In this embodiment, the reinforcing ribs 4 and the reinforcing rods 16 strengthen the connection strength between the crossbar 2 and the vertical rod 1, thereby extending the service life of the ladder.

[0032] Furthermore, a sliding groove 11 is transversely formed on the inner wall surface of the accommodating groove 6 , and a sliding block 10 adapted to the sliding groove 11 is fixedly connected to the surface of the moving block 7 .

After the elastic force of the spring 9 reacts on the moving block 7, an outward thrust of the clamping block 8 is generated. When the clamping block 8 moves to the corresponding position with the card interface 13, the clamping block 8 passes through the interior of the card interface 13, and the bottom horizontal surface of the clamping block 8 contacts the bottom of the inner wall of the card interface 13, so that the two vertical rods 1 can be quickly connected.
