By adjusting the locking connection The distance L between the piece 4 and the locking screw 3 is used to adjust the size of the locking force F: when the distance L is smaller, the locking force F is greater, and the locking effect on the central pipe of the locking shell 1 is better. However, the metal locking piece 2 provided in this case can carry and transmit a relatively large locking force. the

It can be seen from the above technical solution that the metal rotating locking structure provided by the embodiment of the utility model adopts the rotating locking structure of the metal locking piece 2, and has a large contact surface with the locked tube 6, and the structure is firm and reliable. The locking strength of the product is guaranteed, and the switching between locking and loosening with an eccentric wrench is fast and convenient. Compared with the structure in the prior art, the locking effect is better, so that the product is not easy to slide down after locking. the

In the embodiment of this solution, the limiting structure specifically includes a limiting groove formed at the fixed end of the locking metal sheet 2 along the axial direction of the through hole, and a fixing screw 7 for cooperating with the limiting groove. In this way, after the fixed end on the left side of the locking metal sheet 2 is put into the corresponding groove in the locking shell 1, the fixing screw 7 is screwed into the locking shell 1 through the top mounting hole, and the locking metal sheet 2 is screwed into the locking shell 1.

The working process of the metal rotation locking structure in this case is introduced in detail as follows: 

Structural locking state:

Because the locking connecting piece 4 embedded in the eccentric wrench 5 is integrated with the locking screw 3, when the eccentric wrench 5 rotates clockwise to the figure 1, the eccentric wrench 5 is utilized for the eccentric structure of the head. At this time, the eccentric wrench 5 is large.

Structure loose state:

When the overall structure is in a locked state, when the eccentric wrench 5 rotates counterclockwise to the state shown in Figure 2, due to the eccentric structure, the small-sized surface of the eccentric wrench 5 and the concave arc surface of the locking shell 1 will not be in contact at this time. The eccentric wrench 5 , the locking connector 4 and the locking screw 3 are movable, and the eccentric wrench 5 cannot drive the locking connector 4 and the locking screw 3 to generate a downward locking force. However, since the embedded automatic disengagement spring 8 will generate an upward pushing force on the locking metal sheet 2, the overall structure will release the locked tube 6; because the automatic disengagement spring 8 is tapered, the locking The screw rod 3 and the automatic disengagement spring 8 are connected together for rotation, which ensures that the locking screw rod 3 will not rotate and fall when in use or not in use. the

In summary, the metal rotation locking structure provided by the embodiment of the utility model realizes the locking of the locked tube 6 by driving the metal locking piece 2 to rotate through the eccentric wrench 5, so the locking effect and strength are very good. Good; and the fixed screw rod 7 added in the locking shell 1 becomes the rotating shaft of the metal locking piece 2 when locking, so that the metal locking piece 2 rotates around the locked tube 6, fully ensuring that the metal locking piece 2 and the Contacted by the locking tube 6; when the eccentric wrench 5 is loosened, a conical automatic release spring 8 is added to the locking connector 4 and the locking screw 3, which can automatically push the metal locking piece 2 away, To realize the loosening of the locked tube 6, so that the product will not scratch the surface of the tube when it slides later, and protect the appearance of the tube; at the same time, the conical spring is screwed on the locking screw 3, It is ensured that the locking screw rod 3 does not rotate or fall off. the
