The above-mentioned track 3 may include two arc-shaped guide rails. The two guide rails are distributed in parallel and spaced on both sides of the upper end of the base 1, with their two ends facing the two ends of the base 1 respectively. The lower ends of the two guide rails pass through vertical support plates respectively. Installed on the upper end of the base 1, the cross section of the guide rail is designed to be T-shaped. The lower end of the slider 21 is provided with two arc-shaped slide grooves with a T-shaped cross section that are adapted to the guide rail (the slide grooves are coaxially arranged with the guide rail). ), and is mounted on two guide rails through sliding grooves to realize the sliding of the slider 21 relative to the guide rails.

Of course, track 3 can also adopt the following structural form:

The middle area of the bottom of the head support plate 2 is coaxially equipped with an arc-shaped fixed part. The slider 21 is coaxially installed on the bottom of the fixed part, and both side ends of the slider 21 protrude from the fixed part. The two side ends form a gap with the bottom of the head support plate 2. The above-mentioned track 3 includes two strip-shaped track bases 31. The two above-mentioned track bases 31 are distributed in parallel and spaced apart, and the two ends of the two track bases 31 are spaced apart. They extend to both ends close to the base 1. The upper end surfaces of the two rail bases 31 are respectively set as arc surfaces coaxially distributed with the slider 21. The upper ends of the two rail bases 31 are close to each other. Arc-shaped track grooves 311 are respectively provided coaxially with the slider 21 . The guide portions at both sides of the slider 21 extend into the track grooves 311 on both sides in one-to-one correspondence. Through the track grooves 311 The embedded assembly with the two side ends of the slider 21 realizes the limitation of the two and ensures that the two form a relative arc-shaped sliding track.

In the above embodiment, the operating principle of the driving device 4 is: the power device 44 drives the transmission shaft 43 to drive the gear 42 to rotate. When the gear 42 rotates, it drives the rack 41 meshed with it to move. Since the rack 41 is installed at the bottom of the slider 21, At the same time, the slider 21 is fixedly connected to the head support plate 2, and the swing trajectory of the head support plate 2 is an arc shape. Therefore, when the power device 44 outputs power, the head support plate 2 can be driven in the forward and reverse directions. Swinging, the two ends of the head support plate 2 can be raised or lowered at the two ends of the base 1 respectively. The structural design of the entire driving device 4 is simple and reasonable. The gear 42 and the rack 41 themselves can realize self-locking. The head position support plate 2. The accuracy of angle and orientation adjustment during the swing process is relatively high.
