[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] The utility model provides a technical solution, a clamp arm quick replacement structure, please refer to Figure 1 , Figure 2 , including a clamp arm 4, a clamp arm clamping block 5 is provided at one end of the clamp arm 4, inlet and outlet water blocks 3 are provided on both sides of one end of the clamp arm 4, a soft connection 2 is provided above the clamp arm clamping block 5, a cylindrical head screw 1 is connected to the soft connection 2, an internal thread cylindrical pin 6 is installed in the clamp arm clamping block 5, and an equal height screw 7 is installed at the other end of the clamp arm clamping block 5;

[0019] See also Figure 2 , Figure 3 The soft connection 2 is connected to the clamp arm 4 through a cylindrical head screw 1, the clamp arm clamping block 5 is plugged into the end of the clamp arm 4 through an internal thread cylindrical pin 6, and the clamp arm clamping block 5 is connected to the clamp arm 4 through an equal height screw 7. This structure only needs one equal height screw 7 to be fixed.

[0020] In this practical application, Figure 1 , 2As shown, the quick-change structure of the clamp arm 4 includes: a cylindrical head screw 1, a flexible connection 2, an inlet and outlet water dividing block 3, a clamp arm 4, a clamp arm clamping block 5, an internally threaded cylindrical pin 6, and an equal height screw 7.

[0021] The disassembly steps:

[0022] Use the disassembly tool to remove the cylindrical head screw 1 that locks the flexible connection 2. After removing the cylindrical head screw 1, the flexible connection 2 is separated from the clamp arm 4; continue to remove the screw that locks the inlet and outlet water dividing block 3, and the inlet and outlet water dividing block 3 is separated from the clamp arm 4; finally, remove the equal height screw 7. At this time, the U-shaped notch on the clamp arm 4 can be hung on the internal thread cylindrical pin 6 due to the limitation of the external size, and the clamp arm 4 can be adjusted in any direction within 90°; adjust the direction of the clamp arm 4, pull out the clamp arm 4, separate it from the clamp arm clamping block 5 and the internal thread cylindrical pin 6, and remove the clamp arm 4; the result is as follows Figure 3 shown.
