[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only 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 creative work are within the scope of protection of the utility model.

[0022] See also Figures 1 to 5The utility model provides a technical solution: a transmission rod with fixed docking, comprising a No. 1 transmission rod 1, a No. 1 connecting piece 3 is installed on the outer side of the No. 1 transmission rod 1, and a No. 2 transmission rod 2 is arranged at the bottom of the No. 1 transmission rod 1, a No. 2 connecting piece 5 is installed on the outer side of the No. 2 transmission rod 2, an external thread 11 is opened near the center of the No. 2 connecting piece 5, and an internal thread 8 is opened on the inner wall of the No. 1 connecting piece 3, and the internal thread 8 and the external thread 11 are matched.

[0023] See also Figure 2 and Figure 4 Two hand-held pieces 7 are fixedly mounted on the outer wall of the No. 1 connecting piece 3, and the positions of the two hand-held pieces 7 are arranged relatively to each other. This arrangement facilitates the operation of the staff when the No. 1 connecting piece 3 and the No. 2 connecting piece 5 are connected.

[0024] See also Figure 2 and Figure 3 A number of No. 1 clamping blocks 4 are installed on the outer wall of the No. 1 transmission rod 1, and a number of No. 2 clamping blocks 6 are installed on the outer wall of the No. 2 transmission rod 2. Through this arrangement, the movable docking between the No. 2 connecting piece 5 and the No. 2 transmission rod 2 can be limited to ensure the firm performance of the overall docking.

[0025] See also Figure 5 The bottom of the No. 2 connecting piece 5 is fixedly connected to a limiting bracket 9, and the bottom of the limiting bracket 9 is fixedly connected to a limiting ring 10, and the limiting bracket 9 and the limiting ring 10 are movably mounted on the outside of the No. 2 transmission rod 2, and the bottom of the limiting ring 10 is in contact with the top of the corresponding No. 2 block 6. Through this arrangement, the No. 2 connecting piece 5 can be better docked and installed with the No. 2 transmission rod 2, so that the subsequent docking and installation work can be carried out more smoothly.

[0026] See also Figure 3 and Figure 5 The No. 2 transmission rod 2 is set in a regular hexagon, and the inner wall of the limiting ring 10 is set in a regular hexagon. The No. 2 transmission rod 2 and the limiting ring 10 are matched. This arrangement can effectively prevent the No. 2 connecting member 5 from rotating freely on the outside of the No. 2 transmission rod 2 after the No. 2 transmission rod 2 and the No. 2 connecting member 5 are installed, thereby avoiding subsequent insufficient stability.

[0027] See also Figure 4 The outer sides of the two handpieces 7 are both arranged in an arc surface. This arrangement can prevent the outer walls of the handpieces 7 from causing damage to the hands of the staff, thereby improving safety performance.

[0028] See also Figure 3 and Figure 4 Both ends of the No. 1 transmission rod 1 and the No. 2 transmission rod 2 are provided with truncated cone-shaped protrusions. This arrangement can effectively reduce the probability of scratching and damaging the inside of other components during the docking installation of the No. 1 transmission rod 1 and the No. 2 transmission rod 2.

[0029] Working principle: When the present application is in use, firstly, the bottom end of the No. 1 transmission rod 1 is inserted into the interior of the No. 2 connecting piece 5, and the No. 2 connecting piece 5 is embedded in the interior of the No. 1 connecting piece 3, and then the external thread 11 on the No. 2 connecting piece 5 and the internal thread 8 on the No. 1 connecting piece 3 are used to realize the docking between the No. 2 connecting piece 5 and the No. 1 connecting piece 3, and further realize the docking between the No. 1 transmission rod 1 and the No. 2 transmission rod 2, which is convenient to operate.

[0030] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
