[0017] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.

[0018] In the description of this utility model, it should be noted that, unless otherwise specified or limited, the terms "connected" and "connection" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integral connection; mechanical connection, electrical connection; direct connection, or indirect connection through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0019] Figure 1 、 Figure 2 and Figure 3 The fixed frame 1 shown serves as the main body of the tilting mechanism. Two drive spindle bearing blocks 14 are mounted on the circular holes on either side of the frame. A drive spindle 7 is mounted within these two drive spindle bearing blocks 14. The left end hole of the first connecting rod 2 fits over the drive spindle 7 and is connected to it via a key, allowing it to rotate with the drive spindle 7.

[0020] The first connecting rod shaft 8 passes through the circular hole above the fixed frame 1 and is fixed to the fixed frame 1 by a set screw. Deep groove ball bearings 15 are installed on both sides of the left end of the second connecting rod 3. At the same time, the deep groove ball bearings 15 are mounted on the first connecting rod shaft, so that the second connecting rod 3 can rotate on the first connecting rod shaft 8.

[0021] The two holes below the fourth connecting rod 5 each house a diamond-shaped seat bearing 16. Inside these bearings are mounted the second and third connecting rod shafts 9 and 10. The hole at the right end of the second connecting rod 3 fits over the third connecting rod shaft 10 and is secured to it with a set screw. The center hole of the first connecting rod 2 fits over the second connecting rod shaft 9 and is secured to it with a set screw.

[0022] The tilting table 6 has two holes. The right hole holds a fifth connecting rod shaft 12, while the left hole holds a sixth connecting rod shaft 13. A deep groove ball bearing 15 is installed in the hole above the fourth connecting rod 5 and fits over the sixth connecting rod shaft 13. The third connecting rod 4 has a deep groove ball bearing 15 installed in its upper hole and fits over the fifth connecting rod shaft 12. The lower hole of the third connecting rod 4 has a deep groove ball bearing 15 installed in it, with the fourth connecting rod shaft 11 mounted in this bearing. Meanwhile, the right end hole of the first connecting rod 2 passes through the fourth connecting rod shaft 11 and is secured with a set screw.

[0023] effect:

[0024] The fixed frame 1, the first connecting rod 2, the second connecting rod 3 and the fourth connecting rod 5 cooperate with each other through the shaft and the bearing to form a parallelogram. When the motor drives the driving spindle 7 to rotate a certain angle, the driving spindle 7 drives the first connecting rod 2 to rotate the same angle.

[0025] The first connecting rod 2, the third connecting rod 4, the fourth connecting rod 5, and the tilting table 6 cooperate through shafts and bearings to form another parallelogram. Due to the parallelogram structure, the side formed by the two holes on the right side of the first connecting rod 2 and the side formed by the two holes on the tilting table 6 always remain parallel to each other. Therefore, when the motor drives the first connecting rod 2 to rotate a fixed angle, the tilting table 6 will rotate the same angle as the first connecting rod 2, thus achieving controllable rotation of the tilting table 6.

[0026] Based on the above-mentioned ideal embodiment of the present invention, and in accordance with the above description, relevant personnel can make various changes and modifications without departing from the technical scope of the present invention. The technical scope of the present invention is not limited to the content of the specification, but must be determined according to the scope of the claims.
