[0066] Please refer to FIG. 1, FIG. 2 and FIG. 3, in some embodiments of the present disclosure, the first end of the follower 12 is closed, that is, one end of the central through hole of the follower 12 is closed.

[0067] Please refer to FIG. 1, FIG. 2 and FIG. 3, in some embodiments of the present disclosure, the follower 12 and the guide rod 11 satisfy at least one of the following: the inner wall of the follower 12 and the end face of the guide rod 11 form an air cavity a. The guide rod 11 has a gas permeable passage 112, or, referring to FIG. 4, FIG. 5 and FIG. 6, the outer wall of the guide rod 11 and the inner wall of the follower 12 have a gas permeable passage 112. The gas permeable passage 112 is configured to communicate the air cavity a with the outside of the follower 12. It can be understood that during the relative movement of the follower 12 and the guide rod 11 to generate displacement in the axial direction y of the follower 12, the volume of the air cavity a will change. By making the gas permeable passage 112 communicate the air cavity a with the outside of the follower 12, when the volume of the air cavity a changes, the air cavity a can intake and exhaust air through the gas permeable passage 112, which is conducive to making the air cavity a consistent with the air pressure outside the follower 12, and the gas is not easy to hinder the relative movement of the follower 12 and the guide rod 11, thereby facilitating the smoothness of the relative movement of the follower 12 and the guide rod 11.

[0068] Please refer to FIG. 1, FIG. 2 and FIG. 3, it can be understood that in some embodiments of the present disclosure, the air cavity a is formed between the inner wall of the driven member 12 and the end face of the guide rod 11, which means that in the axial direction y of the driven member 12, the air cavity a is formed between the end face of the guide rod 11 close to the first end of the driven member 12 and the inner wall of the driven member 12. Hereinafter, the end of the guide rod 11 close to the first end of the driven member 12 is referred to as the first end of the guide rod 11.

For example, the distance between the end face of the first end of the inner cavity of the driven member 12 and the end face of the first end of the guide rod 11 decreases, the volume of the air cavity a decreases, and the gas in the air cavity a is discharged to the outside of the driven member 12 through the air permeable channel 112, so that the gas in the air cavity a is not easy to cause greater resistance to the relative sliding between the driven member 12 and the guide rod 11.

[0070] Please refer to FIG. 1, FIG. 2 and FIG. 3, it can be understood that in some embodiments of the present disclosure, the air permeable channel 112 can be provided only in the guide rod 11, or only between the outer wall of the guide rod 11 and the inner wall of the driven member 12, or both in the guide rod 11 and between the outer wall of the guide rod 11 and the inner wall of the driven member 12.

[0071] Please refer to FIG. 1, FIG. 2 and FIG. 3, it can be understood that in some embodiments of the present disclosure, the first air permeable channel 1120 is an air permeable hole formed in the guide rod 11, and the air permeable hole communicates the inside and outside of the driven member 12.

[0072] Please refer to FIG. 1, FIG. 4 and FIG. 5, it can be understood that, in some embodiments of the present disclosure, the part of the outer wall of the guide rod 11 that seals with the follower 12 is different from the part of the outer wall of the guide rod 11 that is used to enclose the second air passage.

[0073] Please refer to FIG. 1, FIG. 2 and FIG. 3, in some embodiments of the present disclosure, one end of the air passage hole extends through the end face of the first end of the guide rod 11 to communicate with the air cavity a, and the other end of the air passage hole extends to the outside of the follower 12 through the first opening of the second end of the follower 12 to communicate with the outside of the follower 12. The first end and the second end of the follower 12 are opposite ends of the follower 12 in the axial direction. In this way, the first air passage 1120 independently communicates the air cavity a with the outside of the follower 12.

[0074] Please refer to FIG. 1, FIG. 4 and FIG. 5, in some embodiments of the present disclosure, one end of the second air passage extends to the end face of the first end of the guide rod 11 to communicate with the air cavity a, and the other end of the second air passage extends to the first opening of the second end of the follower 12 to communicate with the outside of the follower 12.

In this structure, at least one of the guide rod 11 or the follower 12 and the sliding bearing 13 form a gap to form the air passage 112, which is convenient to realize, does not need to make great changes to the structure of the sliding bearing 13, and can meet the air permeation requirement.

[0078] Please refer to Fig. 1, one end of the guide rod 11 is adapted to extend into the accommodating cavity of the follower 12 to form the air cavity a with the follower 12, and the air passage 112 is adapted to communicate the air cavity a with the outside.

[0079] In some embodiments of the present disclosure, the follower 12 has an accommodating cavity with an opening facing the direction of the guide rod 11, and the size of the accommodating cavity is matched with the size of the guide rod 11, so that one end of the guide rod 11 can extend into the accommodating cavity of the follower 12 to form a connection relationship that the follower 12 sleeves the one end of the guide rod 11 through the accommodating cavity, so that the relative movement between the follower 12 and the guide rod 11 can be formed, and the volume of the air cavity a will change in the process that the follower 12 and the guide rod 11 relatively move to generate displacement in the axial direction y of the follower 12. By making the air passage 112 communicate the air cavity a with the outside of the follower 12, when the volume of the air cavity a changes, the air cavity a can take in and discharge air through the air passage 112, which is conducive to making the air cavity a consistent with the air pressure outside the follower 12, and the gas is not easy to generate large resistance to the relative movement between the follower 12 and the guide rod 11, thereby being conducive to improving the smoothness of the relative movement between the follower 12 and the guide rod 11.

[0080] Please refer to Fig. 1, Fig. 4, Fig. 5, Fig. 6 and Fig. 7, in some embodiments of the present disclosure, the outer wall of the guide rod 11 is concave in the radial direction, and the first groove (pre-set groove) 111 is formed.

[0081] The first groove 111 is adapted to make the outer wall of the guide rod 11 and the inner wall of the follower 12 have the air passage 112; and / or, the inner wall of the follower 12 is concave in the radial direction, and the second groove is formed to make the outer wall of the guide rod 11 and the inner wall of the follower 12 have the air passage 112. In this structure, by making the outer wall of the guide rod 11 form the first groove 111, the distance between the outer wall of the guide rod 11 and the inner wall of the follower 12 at the first groove 111 is large, so that the outer wall of the guide rod 11 and the inner wall of the follower 12 have the air passage 112, and the air passage 112 is convenient to manufacture. By making the inner wall of the follower 12 form the second groove, the distance between the outer wall of the guide rod 11 and the inner wall of the follower 12 at the second groove is large, so that the outer wall of the guide rod 11 and the inner wall of the follower 12 have the air passage 112, and the air passage 112 is convenient to manufacture.

[0082] Please refer to Fig. 4, in some embodiments of the present disclosure, the first groove 111 is a spiral groove in the axial direction of the guide rod 11.

[0083] Please refer to FIG. 4, the upper end of the guide rod 11 is a connecting portion 113 with external threads, which is used to be connected with the cylindrical cam through threads, and the lower portion of the guide rod 11 is in the shape of an elongated cylinder, and the cylindrical surface has a helical first groove 111, which starts from the bottom end of the guide rod 11 and ends beyond the upper limit position of the follower 12. The cylindrical surface of the helical first groove 111 of the guide rod 11 can be in clearance fit with the sliding bearing 13, and the follower 12 is in interference fit with the sliding bearing 13. In the working state, the helical first groove 111 on the surface of the guide rod 11 is in communication with the accommodating cavity of the follower 12 and the external space, has the function of air permeability, and can reduce the movement resistance of the follower 12. In addition, the helical first groove 111 can also reduce the contact area of the guide rod 11 and the sliding bearing 13, thereby reducing the friction heat.

[0084] Please refer to FIG. 5, FIG. 6 and FIG. 7, in some embodiments of the present disclosure, the first groove 111 is a straight groove in the axial direction of the guide rod 11.

[0085] As shown in FIG. 5, FIG. 6 and FIG. 7, the guide rod 11 has a first groove 111 extending linearly in the axial direction on the outer surface of the guide rod 11, which starts from the bottom end of the guide rod 11 and ends when it is higher than the upper limit position of the follower 12. The first groove 111 extending linearly in the axial direction can be in communication with the accommodating cavity of the follower 12 and the external space of the guide rod 11, thereby reducing the movement resistance of the follower 12 caused by the pressure difference. Compared with the scheme in FIG. 4, the scheme in FIG. 5 can avoid the impact that may be generated between the edge of the helical first groove 111 and the sliding bearing 13 when the sliding bearing 13 moves in the working state.

[0086] Please refer to FIG. 1, FIG. 4 and FIG. 5, of course, in some embodiments of the present disclosure, the first groove 111 and the second groove can also not be provided.

At least one of the first groove 111 and the second groove is a helical groove, which can greatly reduce the contact area between the inner wall of the follower 12 and the outer wall of the guide rod 11, and is beneficial to reduce the friction heat.

[0088] Please refer to FIG. 5, FIG. 6 and FIG. 7, in some embodiments of the present disclosure, at least one of the first groove 111 and the second groove is a helical groove extending along the axial direction y of the driven member 12. At least one of the first groove 111 and the second groove extends to the end face of the guide rod 11 and communicates with the air cavity a.

[0098] With reference to the cross section of the guide rod 11 as shown in Fig. 8, the guide rod 11 can be designed as a variable cross section. In addition, the guide rod 11 can further be designed as a spindle structure.
