[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0025] Example 1: A multi-position adjustable output pump head, such as Figures 1-4 As shown, it includes a pressing head 1 and a liquid supply cylinder 2 installed at the lower end of the pressing head 1. A sealing cylinder 3 is inserted at the lower end of the liquid supply cylinder 2, and a fixing ring 5 is installed at the upper end of the sealing cylinder 3. Support rings 4 are installed at the upper and lower ends of the fixing ring 5. The support ring 4 and the fixing ring 5 are simultaneously inserted with a limit ring 6. A positioning hole 7 is provided on the outer side of the limit ring 6. There are several positioning holes 7, and the positioning holes 7 are located on the corresponding two sides. A supporting hole 8 is opened on the outer side of the support ring 4. The supporting hole 8 is connected with the positioning hole 7, and the positioning hole 7 and the support hole 8 are simultaneously inserted with a positioning rod 9.

[0026] When the device is running, under the support of the sealing cylinder 3 and the liquid supply cylinder 2, the pressing head 1 is pressed to ensure the normal use and stability of the device, and then, under the support of the support ring 4 and the fixed ring 5, the limit stop ring 6 is moved in height. After moving to the accurate position, the positioning rod 9 is moved to be plugged into the positioning hole 7 and the support hole 8 at the same time. Under the fixed support of the support ring 4 on the support hole 8, the positions of the positioning hole 7 and the support hole 8 are limited, thereby achieving the effect of limiting the limit stop ring 6. Under the support of multiple positioning holes 7, The limit stop ring 6 can be fixed at different heights so that the height distance between it and the pressing head 1 can be adjusted, thereby achieving the effect of adjusting the pressing space of the pressing head 1 to multiple specifications. Finally, under the limiting support of multiple positioning holes 7, the limit stop ring 6 can be limited at different heights to limit the pressing distance of the pressing head 1. The device has the performance of multi-gear adjustment, and under the simultaneous guidance and limitation of the support ring 4 and the fixed ring 5, the accuracy of the moving direction of the limit stop ring 6 is guaranteed, and it is convenient to store and place the limit stop ring 6.

[0027] like Figures 1-4 As shown, the fixing ring 5 and the lower support ring 4 are both located outside the sealing cylinder 3 , and the upper support ring 4 is located above the sealing cylinder 3 .

[0028] By arranging the fixing ring 5 and the lower support ring 4 on the outside of the device and only arranging the upper support ring 4 above the sealing tube 3, the gear adjustment component is used in combination with the original device, effectively preventing it from taking up too much space and affecting the compactness and convenience of the device itself, thereby improving the practicality of the device in actual use.

[0029] like Figures 1-4 As shown, a support frame 15 is installed on the upper end surface of the fixing ring 5, and the positioning rod 9 is slidably connected to the support frame 15 and extends into the interior thereof.

[0030] A return spring 10 is mounted on the outer end surface of the positioning rod 9 , and a fixing plate 11 is mounted on the end of the return spring 10 away from the positioning rod 9 . The fixing plate 11 is fixedly mounted on the inner wall of the support frame 15 .

[0031] By fixing the fixed disk 11 inside the support frame 15, one end of the reset spring 10 is fixed, so that when the positioning rod 9 and the reset spring 10 are contracted or pulled, the position of the reset spring 10 itself is stable, and under the limiting guidance of the support frame 15, the moving direction of the positioning rod 9 is guaranteed to be accurate and reliable, thereby improving the direction accuracy of the positioning rod 9 when used in a limiting manner.

[0032] Example 2: A multi-position adjustable output pump head, such as Figures 1-4 As shown, a connecting ring 13 is installed on the outer side of the positioning rod 9, and a transmission rod 12 is installed on the outer end surface of the connecting ring 13. There are at least two transmission rods 12, and the return spring 10 is located between the two transmission rods 12.

[0033] One end of the transmission rod 12 away from the connecting ring 13 is plugged into the fixed disk 11 . The transmission rod 12 extends out of the fixed disk 11 , and an isolation block 14 is plugged into the fixed disk 11 .

[0034] The isolation block 14 is mounted on a side surface of the support frame 15 , and the transmission rod 12 extends out of the isolation block 14 .

[0035] When the gear position of the device needs to be adjusted, the transmission rod 12 is first pulled outward under the simultaneous guidance and limitation of the fixed plate 11, the isolation block 14, and the support frame 15, driving the connecting ring 13 to move simultaneously inside the support frame 15. Based on the fixing effect of the connecting ring 13 and the positioning rod 9, the positioning rod 9 and the return spring 10 will move synchronously to the outside of the device. At the same time, the effect of contracting the return spring 10 is achieved, so that the positioning rod 9 moves out of the limit state. After the position of the limit ring 6 is adjusted and stabilized, the transmission rod 12 is released. At this time, the return spring 10 drives the positioning rod 9 and the connecting ring 13 to return to the position due to its own elastic action. Under the simultaneous limitation of the connecting ring 13 and the outer side of the transmission rod 12, the moving distance of the return spring 10 and the positioning rod 9 is limited, ensuring the accuracy of the distance and direction of the positioning rod 9 during positioning movement, improving the reliability of the gear shifting of the device, and under the isolation support of the isolation block 14, ensuring that there is always a certain distance between the transmission rod 12 and the support frame 15, which is convenient for the movement of the transmission rod 12.

[0036] Working principle: First, pull the transmission rod 12 so that it is pulled outward under the simultaneous guidance and limit of the fixed disk 11, the isolation block 14, and the support frame 15, driving the connecting ring 13 to move simultaneously inside the support frame 15. Based on the fixing effect of the connecting ring 13 and the positioning rod 9, the positioning rod 9 and the return spring 10 will move synchronously to the outside of the device. At the same time, the effect of contracting the return spring 10 is achieved, so that the positioning rod 9 moves out of the positioning hole 7 and the support hole 8, and the limiting state of the limit ring 6 is released. Then, the position of the limit ring 6 is adjusted. After the position of the limit ring 6 is adjusted and stabilized, release the transmission rod 12. At this time, the return spring 10 drives the positioning rod 9 and the connecting ring 13 to reset and move due to its own elastic action, so that the positioning rod 9 is again plugged into the positioning hole 7 and the support hole 8 for limiting and fixing the limit ring 6 after the gear position is adjusted.

[0037] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
