[0028] With reference to the drawings and the embodiments of the present application, the technical solutions in the embodiments of the present application will be described clearly and completely. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by a person of ordinary skill in the art without creative work are within the protection scope of the present application. Figure 1This application provides a cranial dissection table for medical testing and teaching, including a base 6 and a positioning head frame 1. The positioning head frame 1 is mounted on the base 6 via a fixed bracket. The positioning head frame 1 consists of a longitudinal beam 101 and an L-shaped top beam 102 and a bottom beam 103 integrally formed at the upper and lower ends of the longitudinal beam 101. The top beam 102 and the bottom beam 103 form an open skull placement position. The top beam 102 is provided with an upper positioning rod 2 at the skull placement position, and the bottom beam 103 is provided with a lower positioning rod 3 at the skull placement position. Holes are provided at the top and bottom of the skull. The lower positioning rod 3 is inserted into the hole at the bottom of the skull, and the upper positioning rod 2 is movably inserted into the hole at the top of the skull. The upper positioning rod 2 and the lower positioning rod 3 are used to position the skull frame in the skull placement position, with no obstruction around it, which facilitates observation of the skull. Meanwhile, the lower positioning rod 3 is rotatably mounted on the bottom beam 103, and the bottom beam 103 is provided with a damping element 7 to dampen the rotation of the lower positioning rod 3. It can be imagined that by rotating the lower positioning rod 3, the skull can be rotated at any angle on the positioning head frame 1. By using the damping element 7 to dampen the rotation of the lower positioning rod 3, the skull will remain in the position of the demonstration angle and will not rotate arbitrarily if there is no external force to rotate the lower positioning rod 3 after the skull has rotated to the demonstration angle, thus making it convenient for students to observe the skull structure from different angles.

[0029] In a preferred embodiment, to achieve damped rotation of the lower positioning rod 3, such as... Figure 2 As shown, the bottom beam 103 has a shaft hole in the vertical direction, the lower positioning rod 3 is rotatably installed in the shaft hole, and the two ends of the lower positioning rod 3 are integrally formed with end plates 301, which restrict the lower positioning rod 3 in the shaft hole. Meanwhile, the damping component 7 mentioned above includes a damping clamp and a damping spring 703. The damping clamp includes an arc-shaped clamping body 701 that holds the lower positioning rod 3 and a rod arm 702 connected to the arc-shaped clamping body 701. The bottom beam 103 is provided with a clearance hole for the extension and retraction of the damping clamp. The rod arm 702 extends from the clearance hole to the outside of the bottom beam 103 and has a tail plate integrally formed at its end. The damping spring 703 is disposed in the clearance hole, and one end of the damping spring 703 is fixed to the arc-shaped clamping body 701, and the other end is fixed to the hole wall of the clearance hole. The damping spring 703 is in a compressed state in the clearance hole, so that the damping spring 703 applies elastic force to the arc-shaped clamping body 701 to make the damping clamp press against the lower positioning rod 3. At the same time, anti-slip textures are provided on the arc-shaped inner wall surface of the arc-shaped clamping body 701 and the arc-shaped outer wall surface of the lower positioning rod 3, thereby increasing the friction between the arc-shaped clamping body 701 and the lower positioning rod 3. As can be imagined, when the lower positioning rod 3 is rotated, the external force overcomes the damping of the damping spring 703, so that the lower positioning rod 3 can rotate and drive the skull to rotate at any angle. When the external force is removed, the damping spring 703 applies elastic force to the damping clamp to clamp the lower positioning rod 3, so that the skull stays in place without the action of external force for students to observe the skull structure.

[0030] In another preferred embodiment, in order to facilitate the teachers of different heights to operate the positioning rod 3 to rotate the skull, see Figure 1 and Figure 3 As shown, the fixing support includes a first support 4 and a second support 5, wherein the first support 4 includes a first support rod 401 and a second support rod 402 which are inserted into each other, the second support 5 includes a third support rod 501 and a fourth support rod 502 which are inserted into each other, and the third support rod 501 is provided with an adjusting piece 8 for adjusting the height of the second support 5. It can be imagined that by setting the first support 4 and the second support 5 as a telescopic support structure which are movably inserted into each other, and by adjusting the second support 5 through the adjusting piece 8, the first support 4 is synchronously telescoped, so that the lifting of the positioning head frame 1 can be realized.

[0031] As shown in the above Figure 3 , the adjusting piece 8 includes a side plate 801 and a limiting shaft 803, the side plate 801 is obliquely fixed to the outer wall of the third support rod 501, the side plate 801 is integrally formed with the third support rod 501, an inclined guide groove 802 is arranged along the side plate 801, the limiting shaft 803 is arranged to slide in the guide groove 802, the outer wall of the third support rod 501 is provided with a through communication hole which is communicated with the guide groove 802, the fourth support rod 502 is inserted into the third support rod 501, and the side wall of the fourth support rod 502 which faces the communication hole is provided with a clamping groove 9. It can be imagined that when the fourth support rod 502 is pulled up and down, the limiting shaft 803 will be extruded out of the clamping groove 9 and moved along the guide groove 802, and when the external force is removed, the limiting shaft 803 will slide into the clamping groove 9 along the guide groove 802 to limit the movement of the fourth support rod 502, so as to maintain the adjusted height and realize the adjustment of the positioning head frame 1.

[0032] The above only describes the preferred embodiments of the present application, and is not used to limit the present application, any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
