[0017] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model. Therefore, the following detailed description of the embodiments of the utility model provided in the drawings is not intended to limit the scope of the utility model for which protection is sought, but merely represents the selected embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0018] Example

[0019] Combination Figures 1 to 3As shown, this embodiment provides a mounting sleeve for fixing the rod 7 and the base 6, and is placed between the mounting end of the rod 7 and the mounting cavity of the base 6; it includes a main body 1 with a cylindrical thin-walled structure; the main body has a plurality of action surfaces, and the outer side surfaces of the action surfaces are provided with arc-shaped protrusions 2; an open groove 3 is provided between two adjacent action surfaces; at least one side surface of the main body 1 is provided with a through hole 5; the protrusion 2 is configured to: when installed between the mounting end of the rod 7 and the mounting cavity of the base 6, it is deformed so as to form an interference fit between the mounting end of the rod 7 and the mounting cavity of the base 6.

[0020] Specifically, in this embodiment, the body 1 is square, and a limit ring 4 is provided at one end; a through hole 5 is provided on one side of the body 1, and the through hole 5 is adapted to the position of the set screw on the seat; the limit ring 4 well ensures that the through hole 5 and the set screw are in relative position. The setting of the open groove 3 can make the protrusion 2 deform better. Of course, in the case where the interference is too large, a through hole 5 can be provided on one or more sides of the body 1 to reduce the interference during assembly to ensure better assembly.

[0021] Furthermore, the outer side surface of the body 1 forms the arc-shaped protrusion 2 along the axial direction, which is convenient for inserting the sleeve 10 along the axial direction; the inner side surface of the body 1 is an inclined surface, which is convenient for inserting the rod 7 along the axial direction.

[0022] The utility model provides a mounting sleeve 10, which is provided with an arc-shaped protrusion 2, and is deformed when being installed between the mounting end of the rod 7 and the mounting cavity of the base 6, so that an interference fit is formed among the mounting sleeve 10, the mounting end of the rod 7 and the mounting cavity of the base 6, and a tight connection is formed among the three, thereby ensuring that after assembly, the rod 7 will not undergo any radial and circumferential displacement on the base 6, and the rod 7 is fastened by a set screw, thereby ensuring that after assembly, the rod 7 will not undergo axial movement on the base 6, thereby avoiding shaking.
