[0034] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. It should be understood that the specific embodiments described herein are only used to explain the utility model and should not be used to limit the utility model. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0035] As shown in the figure, the embodiment provides a butter gun with adjustable oil output, which comprises: Figures 1 to 5 Gun body 1 is provided with push rod cavity 11, push oil rod 12 is arranged in push rod cavity 11, oil storage area 113 is formed between push oil rod 12 and the bottom wall of push rod cavity 11, and oil outlet 111 and oil inlet 112 are arranged in oil storage area 113; specifically, oil outlet 111 is used for discharging oil in oil storage area 113 outward, and oil outlet 111 can be connected with oil outlet nozzle on gun body 1, and oil inlet 112 is used for absorbing oil in the oil tank into oil storage area 113.

[0036] Oil pushing device 13 is arranged on gun body 1 and connected with push oil rod 12, push oil rod 12 comprises oil pushing position and reset position, and oil pushing device 13 is used for driving push oil rod 12 to switch between oil pushing position and reset position; specifically, when oil pushing device 13 drives push oil rod 12 to move from reset position to oil pushing position, push oil rod 12 extrudes butter in oil storage area 113 through oil outlet 111, and the extruded oil quantity is single oil output quantity; when oil pushing device 13 drives push oil rod 12 to move from oil pushing position to reset position, oil storage area 113 is refilled with oil from the oil tank through oil inlet 112; and,

[0037]

[0038] ​An adjuster 2 is arranged on the gun body 1 and connected with the oil pushing device 13. The adjuster 2 adjusts the reset position of the oil pushing rod 12 by moving the oil pushing device 13 along the gun body 1, and the oil pushing position of the oil pushing rod 12 is unchanged. Specifically, when the oil pushing device 13 is driven to move away from the oil pushing position by the adjuster 2, the oil pushing device 13 drives the oil pushing rod 12 to move away from the oil pushing position along the pushing rod cavity 11, so that the distance between the reset position and the oil pushing position of the oil pushing rod 12 is increased, and the volume of the oil storage area 113 is increased, and the single oil output of the grease gun is increased. When the oil pushing device 13 is driven to move towards the oil pushing position by the adjuster 2, the oil pushing device 13 drives the oil pushing rod 12 to move towards the oil pushing position, so that the distance between the reset position and the oil pushing position of the oil pushing rod 12 is reduced, and the volume of the oil storage area 113 is reduced, and the single oil output of the grease gun is reduced.

[0039] In some embodiments, as shown in Figures 1 to 5 The gun body 1 is provided with an oil pushing device mounting cavity 14, and the oil pushing device mounting cavity 14 is provided with a guide portion 141 extending in a direction parallel to the axial direction of the oil pushing rod 12, and the oil pushing device 13 is in sliding connection with the guide portion 141. The guide portion 141 has two guide portions respectively arranged on the opposite side walls of the oil pushing device mounting cavity 14. Thus, the oil pushing device 13 and the two guide portions 141 cooperate, and the stability of the oil pushing device 13 during sliding is better.

[0040] The guide portion 141 can be a guide rail, and the oil pushing device 13 is in sliding connection with the guide rail. Specifically, the oil pushing device 13 is provided with a sliding groove, and the sliding groove slides along the guide rail.

[0041] In some embodiments, the adjuster 2 includes an adjusting rod 22 arranged between the handle 21 and the oil pushing device 13, and the adjusting rod 22 is in rotational connection with the gun body 1 and the oil pushing device 13.

[0042] In some embodiments, the adjuster 2 includes an adjusting rod 22 arranged between the handle 21 and the oil pushing device 13, and the adjusting rod 22 is in rotational connection with the gun body 1 and the oil pushing device 13. Figures 1 to 3As shown, the adjusting rod 22 is rotationally and axially fixedly connected with the oil pushing device 13, and the adjusting rod 22 is rotationally connected with the gun body 1 in a threaded manner. Specifically, an axial limiting assembly is arranged between the adjusting rod 22 and the oil pushing device 13, so that the adjusting rod 22 and the oil pushing device 13 move synchronously in the axial direction of the gun body 1, specifically in the axial direction of the oil pushing rod 12. When the adjusting rod 22 is rotated clockwise, the adjusting rod 22 moves into the gun body 1 and drives the oil pushing device 13 to slide towards the oil pushing position, and the oil pushing device 13 drives the oil pushing rod 12 to slide towards the oil pushing position, so that the volume of the oil storage area 113 is reduced, and thus the single oil output of the grease gun is reduced. When the adjusting rod 22 is rotated counterclockwise, the adjusting rod 22 moves out of the gun body 1 and drives the oil pushing device 13 to slide away from the oil pushing position, and the oil pushing device 13 drives the oil pushing rod 12 to slide away from the oil pushing position, so that the volume of the oil storage area 113 is increased, and thus the single oil output of the grease gun is increased.

[0043] In another specific embodiment, the adjusting rod 22 is rotationally and axially fixedly connected with the gun body 1, and the adjusting rod 22 is rotationally connected with the oil pushing device 13 in a threaded manner. That is, when the adjusting rod 22 is rotated, the axial distance between the adjusting rod 22 and the gun body 1 does not change, while the positions of the oil pushing device 13 and the oil pushing rod 12 change.

[0044] In order to facilitate the user to operate the adjusting rod 22, the adjusting device 2 further comprises a handle 21 located outside the gun body 1, and the handle 21 is fixedly connected with the adjusting rod 22. That is, the user can drive the adjusting rod 22 to rotate through the handle 21.

[0045] In some specific embodiments, a sealing ring 3 is arranged between the oil pushing rod 12 and the side wall of the pushing rod cavity 11. The sealing ring 3 can play a sealing role to prevent grease from leaking from the pushing rod cavity 11 into the gun body 1.

[0046] In some specific embodiments, as shown in the drawings, Figure 3 As shown, the bottom wall of the pushing rod cavity 11 is provided with a channel 114 communicating with the oil storage area 113, the oil outlet 111 is arranged at the end of the channel 114 away from the reset position, and the oil inlet 112 is arranged on the side wall of the channel 114.

[0047] Working principle:

[0048] When it is needed to reduce the single oil output of the grease gun, the adjusting rod 22 is turned clockwise to move the adjusting rod 22 into the gun body 1 and drive the oil pushing device 13 to slide towards the oil pushing position, and at the same time, the oil pushing device 13 drives the oil pushing rod 12 to slide towards the oil pushing position, so that the distance between the reset position and the oil pushing position of the oil pushing rod 12 is reduced, the volume of the oil storage area 113 is reduced, and the single oil output of the grease gun is reduced.

[0049] The utility model is not limited to the above optional implementation, and each scheme can be combined arbitrarily on the premise of not being contradictory; anyone can derive other various forms of products under the enlightenment of the utility model, but no matter any change in shape or structure, any technical scheme falling within the scope defined by the claims of the utility model falls within the protection scope of the utility model.
