Through the restriction of the outer shell, which can also be other components, during the rising process of the moving part, the lower end of the clamping claw is slowly flipped inward. For details, please refer to the drawings in the specification. Fig.10 In this embodiment, a guide groove 13 can be provided on the outer shell, and this guide groove can be one or a pair. A guide block 22 that can be on the guide groove is provided on the moving part. Preferably, the guide groove is a linear groove, which enables the moving part to move up and down and prevents the moving part from rotating around its central axis.

[0041] Preferably, when the utility model is in use, a pair of corresponding claws are provided, so that it can be ensured that the pulling tube with the gravity hammer and the connecting piece can be held in a balanced manner.

[0042] In one embodiment, a spring 40 is further provided between the outer shell and the moving part, and the spring can impart a downward force to the moving part relative to the outer shell, so that when the pull-out head needs to be reset, it can be reset quickly without jamming.

[0043] The utility model further states that: a gravity hammer 93 is arranged on the outer periphery of the pull-out tube, a connector 94 is arranged on the outer periphery of the pull-out tube located above the gravity hammer, the slot is arranged on the outer peripheral wall of the connector or the gravity hammer with the slot feature (the gravity hammer 93 and the connector 94 are made into one piece), and the connector can support the moving part to move upward relative to the outer shell. It also includes a fixable threaded tube 95. Under normal circumstances, the threaded tube is arranged in a hole on the table (not drawn in the figure), and the outer shell can be screwed with the threaded tube or the threaded tube adapter 97 (when the outer diameter of the threaded tube is large, a threaded tube connector is added, and the threaded tube connector is fixed or interfered in the threaded tube), or other fixed connections, so that the outer shell can be relatively fixed, and a faucet body 90 is arranged above the threaded tube, and the pull-out tube can be arranged in the threaded tube for axial pulling. The water outlet end of the pulling tube is connected with a pulling head 96, and a gravity hammer and a connecting piece are fixed to the outer periphery of the middle part of the pulling tube. The gravity hammer and the connecting piece can also be combined into one piece to become a gravity hammer with a slot feature.

[0044] Specifically, the utility model is a suspendable pull-out faucet, which realizes the suspension of the connector and the gravity hammer through a bouncing mechanism with a heart-shaped groove and a clamping claw limiting structure, thereby realizing the suspension of the pull-out head. The suspension device (mainly composed of an outer shell and moving parts) is installed and fixed on a threaded tube or a threaded tube adapter (when the outer diameter of the threaded tube is large, a threaded tube connector is added, and the threaded tube connector is fixed or interference fit in the threaded tube), and the connector and the gravity hammer (the connector and the gravity hammer can also be combined into one piece to become a gravity hammer with a clamping groove feature) are interference fit on the outer periphery of the pull-out tube. As shown in the state 1 diagram, when the user grabs the pull-out head and pulls it, the pull-out tube moves upward, synchronously driving the connector and the gravity hammer on the pull-out tube to move upward. As shown in the figure of state two, the connecting part and the gravity hammer move upward until the connecting part contacts the movable part and pushes the movable part to move upward, driving the connecting rod to move along the trajectory in the heart-shaped groove (one end of the connecting rod is fixed on the outer shell, and the other end is hooked in the heart-shaped groove of the movable part), while driving the claws on both sides upward and their lower ends move inward; as shown in the figure of state three, when the connecting rod moves to the position shown in the heart-shaped groove of the movable part, the connecting rod is fixed in the second fixed position, the movable part stops, and the claw end at the lower end of the claw is inserted into the groove of the connecting part, and the connecting part is buckled and fixed, so that the pull-out tube is limited and fixed, and the gravity hammer buckled on it cannot pull the pull-out tube back to its position due to the gravity hammer, so that the gravity hammer is suspended, thereby achieving the suspension of the pull-out head. As shown in the figure of state four, after the pulling head is suspended, grab the pulling head again and pull it a short distance. The connecting piece pushes the movable piece to continue to move upward. At this time, the connecting rod moves away from the second fixed position. Under the thrust of the internal spring, the connecting rod is ready to continue moving. The movable piece will move downward, driving the claws on both sides to move downward and outward; when the lower end of the claw is disengaged from the connecting piece slot, the connecting piece and the gravity hammer move freely downward under the action of gravity, driving the pulling tube to move downward to reset the pulling head. When the connecting rod moves to the first fixed position in the heart-shaped groove, the movable piece is limited and pulled to return to the initial state.
