The balls 5 are made of stainless steel, and the rubber ring 3 is made of elastic rubber with toughness. By setting the structure of the balls 5 and the rubber ring 3, the rubber ring 3 is used to tighten and squeeze the balls 5 in the ring groove 2, and then the nozzle is installed and inserted into the nozzle hole 6. The nozzle is squeezed by the balls 5 and inserted into the installation part, so that the nozzle can be installed, so that the nozzle and the connecting seat body 1 can be disassembled and assembled conveniently and quickly.

[0026] A connecting hole 7 is formed through the surface of the connecting seat body 1. The connecting hole 7 is an opening with an inner diameter thread. The connecting hole 7 is connected to the suction nozzle hole 6. The connecting holes 7 are evenly distributed. The evenly distributed connecting holes 7 facilitate the connection seat body 1 to be installed on the equipment for use.

[0027] Embodiment 2

[0028] Reference Figure 1-4 , further improved on the basis of Example 1:

[0029] The angles between the three ball holes 4 are 120°, and the angles between the ball holes 4 are 120°. When the ball 5 is installed in the ball hole 4, three fixing points similar to a triangle are formed, and the triangle has good stability. Therefore, when the suction nozzle is inserted into the suction nozzle hole 6 of the connecting seat body 1, the suction nozzle can be more stably installed on the connecting seat body 1 by using the triangular extrusion fixing method.

[0030] The cross section of the rubber ring 3 is circular, and the cross-sectional diameter of the rubber ring 3 is consistent with the groove width of the annular groove 2. The cross section of the rubber ring 3 is consistent with the groove width of the annular groove 2, so that when the rubber ring 3 is inserted into the annular groove 2, the rubber ring 3 can have a better fixing effect, and then when the rubber ring 3 squeezes and fixes the ball 5, it is more stable.

[0031] The ball 5 is embedded in the ball hole 4 with the central axis as the dividing line, and the spherical parts protruding on both sides of the ball 5 are of the same size, and the protruding parts of the ball 5 on both sides of the ball hole 4 are consistent. When the suction nozzle is inserted into the suction nozzle hole 6, the rubber ring 3 and the suction nozzle act on the ball 5, so that the suction nozzle is squeezed and fixed in the suction nozzle hole 6, so that the suction nozzle can be quickly plugged in and out for use, and when installed and used, the suction nozzle is more stable to prevent the suction nozzle from rotating.

[0032] The working principle of the utility model is as follows: before use, the nozzle connecting seat needs to be assembled first, and the ball 5 is embedded in the ball hole 4 when the connecting seat body 1 is manufactured. During subsequent use, the rubber ring 3 is sleeved into the annular groove 2, and the rubber ring 3 squeezes and fixes the ball 5 in the ball hole 4. Then the nozzle is installed and inserted through the nozzle hole 6. During the insertion process, the insertion part of the nozzle squeezes the ball 5 outward, and the rubber ring 3 squeezes inward at the same time. The installation part of the nozzle is provided with a circle of grooves for adapting to the ball 5 and squeezing the ball outward, so that the ball 5 fixes the nozzle to the nozzle hole 6 of the connecting seat body 1, and the installation and fixation of the nozzle is completed.
