[0026] The present invention will be further described below with reference to specific embodiments: like Figure 1 and Figure 2As shown, a labor-saving grease gun nozzle includes a pressing component 1 and a grease nozzle body. The grease nozzle body and the pressing component 1 are connected by a screw 9. The pressing component 1 is provided with a fixed through hole 2 and a movable groove 3 that allows the screw 9 to move within the movable groove. Compared with the existing grease gun nozzle structure, it has been optimized and simplified. By simply setting the movable groove 3 on the pressing component 1, the pressing and releasing of the grease gun nozzle can be smoothly achieved. Moreover, due to the structural connection method of the movable groove 3, it is more labor-saving and convenient for users to press the pressing component 1.

[0027] As a further improvement, one end of the pipe body 4 is provided with a nut 11 for connecting a grease gun. The grease gun nozzle is connected to the grease gun through the nut 11. The grease nozzle body includes the pipe body 4, a first fixing member 5, and a second fixing member 6. The first fixing member 5 and the second fixing member 6 have through holes in their centers and are fitted onto the cylindrical pipe body 4, so that both the first fixing member 5 and the second fixing member 6 can rotate relative to the pipe body 4. In existing grease gun nozzles, the nut 11 at the bottom of the pipe body 4 is fixed. During the installation of the connecting nut 11 or during the grease application of bearings and other components, the user can easily deform or twist the pipe connected to the nut 11 at the bottom of the pipe body 4. However, with the structure described in this application, the user will not twist the part connected to the nut 11 at the bottom of the pipe body 4 into a twist or deform the pipe during use, thus affecting the grease application.

[0028] As a further improvement, an outer spring sleeve 7 is provided on the pipe body 4 between the first fixing member 5 and the second fixing member 6. Threaded holes 8 are provided on both sides of the first fixing member 5 and the second fixing member 6. An annular movable ring 10 is provided between the first fixing member 5 and the screw 9. The movable ring 10 is located in the movable groove 3 of the pressing member 1 and is limited by the screw 9. The pressing member 1 is fixedly connected to the second fixing member 6 by the screw 9 passing through the fixed through hole 2. The movable ring 10 can convert the static friction between the screw 9 and the edge of the movable groove 3 into rolling friction, so that the user can press the pressing member 1 of the grease gun nozzle more effortlessly and easily, thus facilitating the user to connect the grease gun nozzle to the part to be injected with grease.

[0029] As a further improvement, the diameter of the screw head is larger than the width of the movable groove 3, which can prevent the screw 9 from falling out of the movable groove 3 during use.

[0030] As a further improvement, the pipe body 4 and the nut 11 are integrally formed, and the clamp 15 and the pipe body 4 are integrally formed. The above-mentioned integral forming method results in fewer accessories and a simpler structure, which facilitates worker installation and saves manufacturing costs. The pipe body 4 is provided with an annular groove 12, and a retaining ring 13 is provided on the annular groove 12 to restrict the position of the first fixing member 5 between the nut 11 and the retaining ring 13. The first fixing member 5 is restricted between the retaining ring 13 and the nut 11 by the retaining ring 13 alone. Similarly, the limiting function is achieved through a simple structure.

[0031] As a further improvement, the second fixing member 6 extends to one side to form a clamping sleeve 14. The end of the pipe body 4 is symmetrically and evenly provided with clamps 15. There is a gap between adjacent clamps 15. The inside of the clamp 15 is provided with a fixing sleeve 16. The fixing sleeve 16 is provided with an injection nozzle 17. An inner spring 18 is provided below the injection nozzle 17. The clamps 15 can firmly connect the entire grease gun nozzle to the part to be greased.

[0032] As a further improvement, the injection nozzle 17 is shaped as a cylinder and a frustum with internal through holes stacked together. This shape design ensures that the butter flows smoothly and easily from the frustum side to the cylinder side. The injection nozzle 17 is made of rubber.

[0033] As a further improvement, the pressing member 1 extends with an upwardly angled pressing plate 18, which allows the user to press the pressing plate 18 downward to a greater extent. The pressing plate 18 is provided with a number of anti-slip protrusions 19, which have good anti-slip function.

[0034] The above embodiments are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made to the structure, shape, and principle of the present invention should be covered within the scope of protection of the present invention.
