The invention will be further explained by means of specific embodiments with reference to the drawings, in which:

referring to fig. 1, 4 and 5, an embodiment of a pressing mechanism for oil seal lubrication includes a pressing body b1 and a pressing block b2, wherein the pressing block b2 is connected to the pressing body b1 and is higher than the lower surface of the pressing body b1, the pressing block b2 is provided with a hollow part, and the hollow part and the lower surface of the pressing body b1 form a combined cavity together. The pressing body b1 is a base body, a cylinder is selected as shown in the figure, and the pressing body b1 can be lifted by external power, such as directly using human hands or connecting with an ejector. The pressing block b2 is a core carrier, and it can be formed integrally with the pressing body b1, or can be an independent block fixedly connected with the pressing body b1 (such as welded, screwed, etc.), in the figure, the pressing block b2 is a hollow ring, and for better liquid-discharging effect, the pressing block b2 is matched with the shape of the liquid-absorbing medium a 2. Since the pressing is performed by the pressing block b2, the pressing block b2 is certainly higher than the lower surface of the pressing body b1, and the combined cavity formed by the hollow part of the pressing block b2 and the lower surface of the pressing body b1 is used for avoiding interference and pressing with the oil seal during pressing, and the inner contour of the combined cavity can be close to and slightly larger than the oil seal, and can also play a certain role in pushing back to positive when the horizontal position of the oil seal is slightly incorrect, and also provides an absorption space for absorbing the oil seal by negative pressure mentioned later.

The position limiting cap b6 may be a part integrally formed at the upper end of the adjusting guide or a separate connection cap fixedly connected to the upper end of the adjusting guide. When the pressing block b2 presses the liquid absorbing medium a2, due to the existence of the adjusting guide rod b4, the pressing block b2 can move upwards due to the reaction force, and due to the existence of the adjusting spring b5, the upward moving distance of the pressing block b2 can be limited, so that the pressing block b2 can buffer when pressing the liquid absorbing medium a2, the lubricating liquid splashing caused by too fast and too strong pressing can not occur, the liquid absorbing medium a2 can be pressed with proper force, the liquid absorbing medium a2 can not be pressed excessively, and the release amount of the lubricating liquid is also smooth and sufficient. In addition, the extrusion degree can be finally changed by directly replacing the adjusting spring b5 with different elasticity or the adjusting guide rod b4 with different length, but a better adjusting mode is provided, namely, an external thread section is arranged at the upper part of the adjusting guide rod b4, an internal thread section is arranged on the limiting cap b6, the limiting cap b6 can be simply used as a nut, the limiting cap b6 is fixed with the adjusting guide rod b4 in a threaded manner, the pre-compression amount of the adjusting spring b5 and the height of the pressing block b2 are changed by rotating the limiting cap b6, and finally, the fine adjustment is carried out on the extrusion effect of the pressing block b 2.
