[0027] Embodiment 2
[0028] As shown in the figure, Figure 1 and Figure 2 the specific scheme of the adjusting mechanism is given on the basis of embodiment 1, wherein the adjusting mechanism comprises two ear plates 4 arranged on the top of the fixing seat 1, the two ear plates 4 are vertically arranged, a horizontal rotating shaft 5 is arranged between the two ear plates 4, and the two ends of the horizontal rotating shaft 5 are limited by bearings installed on the ear plates 4, one end of the horizontal rotating shaft 5 is provided with a transmission turbine 8, the transmission turbine 8 is in transmission cooperation with a worm 9, one end of the worm 9 is rotatably connected with a driving motor 10, and the driving motor 10 is fixedly installed on the outside of the ear plate 4; a rotating seat 6 is fixedly sleeved on the horizontal rotating shaft 5, an electric rotary table 7 is arranged on the rotating seat 6, and the shaking mechanism is arranged on the electric rotary table 7.
[0029] The driving motor 10 of the present solution can drive the rotating seat 6 to rotate in the vertical plane under the transmission action of the worm 9, the transmission turbine 8 and the horizontal rotating shaft 5, and can realize the adjustment of the vertical, horizontal, pitching and tilting body positions of the head model 2 in cooperation with the electric rotary table 7 on the rotating seat 6, so as to more truly simulate the body position of the child's head when puncturing different positions of the scalp; at the same time, the cooperation of the worm 9 and the transmission turbine 8 makes the horizontal rotating shaft 5 have self-locking performance, so as to fix the body position of the head model 2.
[0030] Embodiment 3
[0031] As shown in the figure, Figure 1As shown, the embodiment is based on example 2, and gives the specific scheme of the shaking mechanism. The shaking mechanism includes a circular base 11 and a circular shaking base 12. The circular base 11 is fixedly connected with the electric rotating table 7. The middle part of the circular base 11 is fixedly connected with one end of a supporting rod 13. The other end of the supporting rod 13 is movably connected with the middle part of the circular shaking base 12 through a spherical joint 14. Four electric telescopic cylinders 15 for jacking the circular shaking base 12 to be offset are uniformly arranged on the circumference of the circular base 11. The four electric telescopic cylinders 15 are all electrically connected with the controller. In specific implementation, the front ends of the four electric telescopic cylinders 15 are all abutted on the circular shaking base 12. The state of the circular shaking base 12 being parallel to the circular base 11 is taken as the initial state. The two electric telescopic cylinders 15 located on the opposite sides are taken as a group, and there are two groups in total. The controller is used to drive the extension and retraction amounts of the two electric telescopic cylinders 15 of each group to be zero at any moment, that is, one of the two electric telescopic cylinders 15 of each group is extended and the other is retracted, and the extension amount is equal to the retraction amount.
