[0005] Furthermore, a spiral guide groove is provided on the inner wall of the lower suction nozzle, and a guide block is arranged outside the lower suction nozzle, and the guide block cooperates with the spiral guide groove.
[0006] Furthermore, a mark is set on the column of the upper suction nozzle, and the mark is consistent with the position where the second suction hole is connected to the suction channel and the third suction hole is connected to the suction channel.
[0007] After adopting the above structure, the utility model has the following beneficial effects:
[0008] The utility model is provided with a plurality of suction holes connected with the suction channel, so as to adjust the suction range of the suction nozzle, and can suck smaller components as well as larger components, and has a simple structure, reasonable design, convenient operation and reduced cost.

[0014] The utility model is further described below in conjunction with the accompanying drawings.
[0015] 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.
[0016] See also Figure 1-3 An adjustable suction nozzle includes an upper suction nozzle 1 and a lower suction nozzle 2. The upper suction nozzle 1 is a T-shaped structure as a whole and is threadedly connected to the lower suction nozzle 2. An air suction channel 3 is provided on the central axis of the upper suction nozzle 1. A plurality of through holes 4 are provided on the outside of the air suction channel 3, and the through holes 4 are connected to the air suction channel 3. A first suction hole 5 is provided on the central axis of the lower suction nozzle 2. The top of the first suction hole 5 is raised and embedded in the air suction channel 3, and the first suction hole 5 is connected to the air suction channel 3. A plurality of second suction holes 6 are provided in an annular array outside the first suction hole 5, and a plurality of third suction holes 7 are provided in an annular array outside the second suction hole 6. When the upper suction nozzle 1 moves upward or the lower suction nozzle 2 moves downward, the through holes 4 are connected to the second suction hole 6 and the third suction hole 7 in sequence. Specifically, when sucking small components, the first suction hole 5 is connected to the air suction channel 3 (see Figure 1 ); When it is necessary to suck a slightly larger component, the upper suction nozzle 1 is rotated upward, or the lower suction nozzle 2 is rotated downward, until the second suction hole 6 is connected with the through hole 4, and thus connected with the suction channel 3 (see Figure 2 ); When it is necessary to suck larger components, the upper suction nozzle 1 is further rotated upward, or the lower suction nozzle 2 is further rotated downward, until the third suction hole 7 is connected with the through hole 4, thereby connecting with the suction channel 3 (see Figure 3 ); simple and convenient operation, reducing manufacturing costs; the through hole 4 is preferably a strip hole or a waist-shaped hole, which increases the probability and area of connection with the second suction hole 6 and the third suction hole 7, which is conducive to absorbing components.
[0017] In this embodiment, a spiral guide groove 8 is provided on the inner wall of the lower suction nozzle 2, and a guide block 9 is provided on the outside of the lower suction nozzle 2, and the guide block 9 cooperates with the spiral guide groove 8. The cooperation between the guide block 9 and the spiral guide groove 8 is, on the one hand, to limit the up and down movement of the through hole 4 to avoid misalignment with the second suction hole 6 and the third suction hole 7, and on the other hand, to prevent the upper suction nozzle 1 and the lower suction nozzle 2 from being separated.
[0018] In this embodiment, a mark (not shown) is set on the column of the upper suction nozzle 1, and the mark is consistent with the position where the second suction hole 6 is connected to the suction channel and the third suction hole 7 is connected to the suction channel. It includes two marks. When one mark is displayed, it means that the second suction hole is connected to the suction channel; when the second mark is displayed, it means that the third suction hole is connected to the suction channel; it provides a reference for the operator, so that there is no need to operate blindly, which improves convenience.
[0019] The above description is only used to illustrate the technical solution of the utility model rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the utility model by ordinary technicians in this field should be included in the scope of the claims of the utility model as long as they do not depart from the spirit and scope of the technical solution of the utility model.
