[0016] The utility model is further described below in conjunction with the accompanying drawings.

[0017] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the specific implementation methods described here are only used to explain the utility model and are not used to limit the utility model.

[0018] See also Figure 1 A split suction nozzle comprises a tube body 1, an external tube 2 is arranged at the rear end of the tube body 1, a connecting tube 3 is arranged at the front end thereof, and a suction nozzle 4 is also included. The suction nozzle 4 is detachably connected to the connecting tube 3, a limiting ring 5 is arranged on the connecting tube 3, a plug 6 is arranged at the rear end of the suction nozzle 4, the plug 6 is embedded in the connecting tube 3, a rubber installation sleeve 7 is arranged on the outside of the plug 6, the cross section of the installation sleeve 7 is an L-shaped structure, and has an annular clamping tooth 71, a locking ring 8 is arranged on the outside of the connecting tube, and the locking ring 8 is externally threadedly connected to a locking nut 9, the cross section of the locking ring 8 is an L-shaped structure, and the locking ring is a truncated cone structure, and a plurality of wire grooves 81 are provided on the surface, dividing the locking ring into a plurality of blades 82, when the plug 6 is embedded in the connecting tube 3, the installation sleeve 7 is embedded in the area between the connecting tube 3 and the locking ring 8, and the annular clamping tooth 71 cooperates with the limiting ring 5, and then the locking ring 8 is tightened by the locking nut 9, and the installation sleeve 7 is pressed and fixed. Specifically, when installing the suction nozzle 4, the insert tube 6 is embedded in the connecting tube 3, and the installation sleeve 7 is embedded in the area between the connecting tube 3 and the locking ring 8. As the installation sleeve 7 goes deeper, the annular clamping tooth 71 hooks the limiting ring 5 for preliminary fixation, and then the blade 82 is tightened by the locking nut 9, so that the locking ring 8 presses and fixes the installation sleeve 7, thereby realizing the installation of the suction nozzle 4, and it is also beneficial to sealing and improving the sealing effect; when the suction nozzle 4 needs to be removed, it is only necessary to loosen the locking nut and pull the suction nozzle out with force so that the annular clamping tooth and the limiting ring 5 are separated; the external tube 2 is connected to the external suction equipment; in order to avoid damage to the chip, the suction nozzle 4 can be made of rubber material.

[0019] In this embodiment, an annular mounting groove is provided on the outside of the insert tube 6, and the mounting sleeve 7 is embedded in the mounting groove to prevent the mounting sleeve 7 from being easily displaced or falling off.

[0020] In this embodiment, the connecting pipe 3 and the limiting ring 5 are integrally formed to increase the service life.

[0021] In this embodiment, the installation sleeve 7 is a wide-mouth structure, which facilitates the cooperation between the annular locking teeth 71 and the limiting ring 5 .
