[0013] 1. In the utility model, the threading hole of the bowl head hanging plate body is improved and a guide wheel is provided to effectively reduce the wear between the wire and the threading hole.

When the wire is displaced left and right, the guide wheel 9 is subjected to force, so that the sliding block 7 is driven to slide left and right, and at the same time the reset spring 6 begins to contract. Under the elastic force of the reset spring 6, it can play a buffering role. The pressure generated by the entire displacement deformation is effectively reduced through the buffering effect, which effectively prevents the wear of the wire and the guide wheel 9 due to external force, thereby improving the service life of the bowl head hanging plate main body 1.

[0024] Embodiment 2, as Figure 1 - Figure 4 As shown, a vertical hanging plate 10 is provided at the bottom of the bowl head hanging plate body 1, and a threaded hole 11 is provided on the surface of the vertical hanging plate 10. A bolt 12 is threadedly connected to the inner thread of the threaded hole 11, and a nut 13 is threadedly connected to the outer surface of the bolt 12. A buffer pad 14 is provided on the outer surface of the vertical hanging plate 10, and the material of the buffer pad 14 is rubber. The reset spring 6 is sleeved on the outer surface of the fixed rod 5, and the sliding block 7 is slidably connected to the outer surface of the fixed rod 5. One side of the sliding block 7 is fixedly connected to the reset spring 6, and the threading hole 3 is connected to the inside of the groove 2, and the shape of the groove 2 is set to be bowl-shaped.

[0025] The effect achieved by the entire embodiment 2 is that a vertical hanging plate 10 is provided at the bottom of the bowl head hanging plate body 1, and a threaded hole 11 is provided on the surface of the vertical hanging plate 10.

The nut 13 fixes the bolt 12 on the vertical hanging plate 10, and the nut 13 makes it easy for the bolt 12 to pass through the vertical hanging plate 10, and then is sleeved on the outer surface of the fixed rod 5 through the reset spring 6. The sliding block 7 is slidably connected to the outer surface of the fixed rod 5, and one side of the sliding block 7 is fixedly connected to the reset spring 6. When the wire is displaced left and right, the guide wheel 9 is forced to drive the sliding block 7 to slide left and right on the fixed rod 5.

[0026] Working principle: By improving the threading hole 3 of the bowl head hanging plate body 1, a guide wheel 9 is provided to effectively reduce the wear between the wire and the threading hole 3. When the wire is displaced left and right, the guide wheel 9 is subjected to force, so that the sliding block 7 is driven to slide left and right on the fixed rod 5. When the sliding block 7 slides left and right, the reset spring 6 is subjected to force and begins to shrink. Under the elastic force of the reset spring 6, it can play a buffering role. The pressure generated by the entire displacement deformation is effectively reduced through the buffering effect, and the wear of the wire and the guide wheel 9 due to external force is effectively prevented, thereby improving the service life of the bowl head hanging plate body 1. After the wire is inserted into the threading hole 3, the bolt 12 is tightened. The buffer pad 14 can buffer the force applied by the bolt 12 to the vertical hanging plate 10, thereby preventing the vertical hanging plate 10 from breaking. The nut 13 fixes the bolt 12 on the vertical hanging plate 10, and the nut 13 makes it easy for the bolt 12 to pass through the vertical hanging plate 10.
