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.

[0022] Reference Figure 1 - Figure 3 The utility model provides an embodiment: a medium-speed placement machine nozzle, including a mounting block 1, the mounting block 1 is internally rotatably connected with a bidirectional threaded rod 2, and the left and right sides of the outside of the bidirectional threaded rod 2 are threadedly connected with threaded sleeves 3. It is designed here that the threaded sleeves 3 can be displaced by rotating the bidirectional threaded rod 2. The adjacent sides of the two threaded sleeves 3 are fixedly connected with fixing rings 4. The inner walls of the fixing rings 4 are designed here not to contact the bidirectional threaded rod 2. The front and rear sides of the two fixing rings 4 are fixedly connected with card plates 5. The card plates 5 are designed here to limit the fixing rings 4. The middle side of the outside of the bidirectional threaded rod 2 is rotatably connected with a fixing core 6. The four internal corners of the fixing core 6 are provided with card slots 7. The card slots 7 are designed here as the card plates 5. The locking space is provided, and a pulling assembly is arranged on the right side of the bidirectional threaded rod 2, and the pulling assembly includes a pulling plate 8, and the left side of the pulling plate 8 is fixedly connected to the right side of the bidirectional threaded rod 2. It is designed here that the bidirectional threaded rod 2 is driven to rotate by rotating the pulling plate 8. A suction nozzle assembly is provided at the bottom of the fixed core 6, and the suction nozzle assembly includes a rubber disk 12. The top of the rubber disk 12 is fixedly connected to the bottom of the fixed disk 11. It is designed here that the rubber disk 12 can make the suction nozzle more adaptable. A suction nozzle head 13 is fixedly connected to the bottom of the fixed core 6, and the outside of the fixed core 6 is slidably connected to the fixed plate 9, and the outer sleeve of the fixed core 6 is provided with a spring 10. It is designed here that the suction nozzle can be protected by means of compression and rebound of the spring 10, and the outer bottom side of the fixed core 6 is slidably connected to the fixed disk 11.

[0023] Reference Figure 2 - Figure 3 , the four internal corners of the mounting block 1 are provided with sliding grooves, the outside of the card plate 5 is slidably connected to the inside of the sliding groove of the mounting block 1, the sliding groove is designed here to limit the card plate 5, so that the fixing ring 4 can make a linear displacement, the outside of the threaded sleeve 3 is slidably connected to the inside of the mounting block 1, the outside of the threaded sleeve 3 is slidably connected to the inside of the mounting block 1, the outside of the card plate 5 is slidably connected to the inside of the card slot 7, the card plate 5 is designed to slide in and out of the card slot 7 to achieve the engagement with the fixed core 6, the outside of the fixing ring 4 is slidably connected to the top of the fixing core 6, the sliding of the fixing ring 4 is designed here to make the card plate 5 slide into the inside of the card slot 7, one end of the spring 10 is fixedly connected to the bottom of the fixing plate 9, and the other end of the spring 10 is fixedly connected to the top of the fixing disk 11, and the design here can achieve buffering of the suction nozzle with the help of compression and rebound of the spring 10.

[0024] Working principle: when the suction nozzle needs to be replaced, it is only necessary to rotate the pull plate 8, and the rotation of the pull plate 8 will drive the bidirectional threaded rod 2 to rotate, and the bidirectional threaded rod 2 will rotate inside the mounting block 1. At this time, as the bidirectional threaded rod 2 rotates, the threaded sleeve 3 will be displaced, and as the threaded sleeve 3 is displaced, the fixing ring 4 will slide inside the mounting block 1, and as the fixing ring 4 is displaced, the clamping plate 5 will be displaced synchronously with the fixing ring 4. When the outside of the fixing ring 4 is separated from the top of the fixing core 6, the clamping plate 5 will be separated from the inside of the card slot 7, and the fixing core 6 can be taken out from the inside of the mounting block 1, and the suction nozzle can be replaced. At this time, the suction nozzle is aligned to the inside of the mounting block 1 and aligned upward. At this time, rotating the pull plate 8 again will cause the threaded sleeve 3 to be displaced again, and then the fixing ring 4 can slide into the top of the fixing core 6, and the clamping plate 5 can slide into the inside of the card slot 7, and the fixing core 6 is engaged, and the replacement of the fixing core 6 can be completed.
