The arcuate slots 40 are movably disposed in the two positioning through holes 311.

In the embodiment, the locking tongue 30 is elastically stretched and positioned on the side of the pressing block 31 toward the riser 1 , and a positioning hole is formed on a side of the pressing block 31 facing the riser 1 . The positioning hole is communicated with the positioning slot 310, and a spring 8 is disposed. The spring 8 is movably disposed through the positioning hole, and one end of the spring is relatively fixed with the positioning hole, and the spring is further One end is fixedly connected to the locking tongue 30;

The structure of the locking tongue 30 toward the end of the riser 1 can be disengaged and stopped in any of the tooth slots of the ratchet surface 10: the locking tongue 30 forms a bevel structure toward one end of the riser 1 . The ramp matches the indentation on the ratchet face and the bevel is capable of disengaging and positioning any of the indentations that are inserted into the ratchet face 10.

In the embodiment, the sliding block 3 further includes a pair of elongated limiting blocks 32, which are vertically and fixedly positioned on the pressing block 31 toward the riser 1 On the side, the locking tongue 30 is movable between the pair of elongated limiting blocks 32, and the pair of elongated limiting blocks 32 can be detached and pressed against the riser 1 by the pressing block 31. And the distance between the pair of elongated limiting blocks 32 and the pressing block 31 can be positioned and adjusted.

The distance between the pair of strip-shaped limiting blocks 32 and the pressing block 31 can be adjusted and adjusted. The pressing block 31 is provided with a plurality of first threaded through holes, and the pair of long strip-shaped limiting blocks are opened. a second threaded through hole is respectively defined in the position corresponding to the plurality of first threaded through holes, and a plurality of screws 9 are further disposed, and the screws 9 are sequentially threaded through the corresponding first threaded through holes and The second threaded through hole, and each of the screws 9 can drive the corresponding limit block 32 to move slightly relative to the riser.

The operation mode of the present invention is as follows: the other end of the locking handle 4 is rotated, and one end of the locking handle 4 is rotated correspondingly. Since the sliding block 3 can move freely in the axial direction of the sliding tube in the sliding tube, the end of the locking handle 4 is driven. The rotation of the arcuate groove 40, the arcuate groove 40 can pull or push the cylindrical pin 5 correspondingly to move away from and close to the riser 1 , and the cylindrical pin 5 simultaneously drives the pressing block 31 to move accordingly, so the locking tongue 30 can be correspondingly relaxed and opposite The force of the tube 1 or against the riser 1;

When the other end of the locking handle 4 is at the highest position, the pair of elongated limiting blocks 32 relax the force of the opposing tube 1, and the locking tongue 30 is disengaged from any of the tooth slots on the ratchet surface 10. The upper riser 1 is freely adjusted with respect to the upper and lower positions of the adjustment pipe 2; then, the other end of the lock handle 4 is rotated downward, and the arcuate groove 40 pushes the cylindrical pin 5 toward the riser 1 and the cylindrical pin 5 simultaneously drives The pressing block 31 moves toward the riser 1 , and one end of the locking handle 4 can also move the locking tongue 30 toward the riser 1 by the pressing spring 8 , and the locking tongue 30 is inserted on the ratchet surface 10 . In the indentation, but the pair of elongated limiting blocks 32 continue to be in the relaxed state of the opposing tube 1, the riser 1 can move upward due to the unidirectional movement of the ratchet surface, but cannot move downward. Then continue to rotate the other end of the locking handle 4 downward, the locking tongue 30 continues to move toward the riser 1 until the locking tongue 30 completely stops in any of the tooth slots on the ratchet surface 10, and the pair of strips The shape limiting block 32 is pressed against the riser 1, and the riser 1 cannot move up or down. Adjusted relative to a fixed tube 1 tube 2 position. Therefore, the locking mechanism has three working positions, which is convenient to operate and has high locking firmness.

In the present invention, a spacer is detachably fixed between the pair of the limiting block 32 and the pressing block 31 and the outer edge of the positioning hole on the pressing block 31. In addition, when the pair of the limiting blocks 32 are used for a long time, the pair of the limiting blocks 32 may wear toward the end surface of the riser to affect the fixing of the position of the vertical pipe. In this case, the screw is screwed in the direction of the riser. The pair of limiting blocks 32 can be pushed forward in the direction of the riser; when the pair of limiting blocks 32 are severely worn, only the pair of limiting blocks 32 can be replaced.
