Embodiment
Below with reference to accompanying drawing, preferred embodiment of the present utility model is described in detail；It is it should be appreciated that it is preferred that real
Example is applied only for illustrating the utility model, rather than in order to limit the scope of protection of the utility model.
Reference in Figure of description includes：Pedestal 1, support frame 2, electromagnet 3, fixed seat 4, iron lance 5, beat
Batting 6, compression spring 7, animal fixed platform 8, bottom plate 9, L-type plate 10, pressing plate 11, block 12, dolly 13, baffle plate 14, tank
15th, guide rod 16.
Embodiment 1：
Embodiment is basic as shown in accompanying drawing 1 and 4：Minitype animal experiment brainpan damage percussion device is caused to be mainly included in pedestal
Electromagnet 3, iron lance 5 and the animal fixed platform 8 laterally set gradually on 1, electromagnet 3 are arranged on support frame 2, and are propped up
Support 2 is slidably on pedestal 1；Iron lance 5 is located in fixed seat 4 by compression spring 7, and it is fixed towards animal
The corresponding end of platform 8 is provided with strike ball 6, and fixed seat 4 is removably supported on pedestal 1；Animal fixed platform passes through movement
Unit can deviate from the motion of strike ball 5 direction relative to pedestal 1, and the mobile unit is dolly 13, and animal fixed platform 8 is arranged on
On dolly 13, pedestal 1 is provided with the guide rail (not shown) being slidably matched with the wheel (unmarked) of dolly 13, and pedestal 1 is remote
The distal end of strike ball 6 is provided with the baffle plate 14 being in contact with animal fixed platform 8；Animal fixed platform 8 includes bottom plate 9 and L-type plate
10, the both ends of bottom plate 9 are slidably disposed on two alar walls of L-type plate 10 respectively；Fixed seat 4, which is provided with, to be used to measure pressure
The master scale chi of the decrement of spring 7；On iron lance 5 positioned at the both sides of compression spring 7 and from close to strike ball 6 to remote
Strike ball 6 direction is additionally provided with for the pressing plate 11 of compression pressure spring 7 and for preventing iron lance 5 from ejecting fixed seat successively
4 block 12.
Using such scheme, animal is fixed in animal fixed platform first, and by animal fixed platform installed in small
Che Shang；Then, promote dolly to be moved to strike direction of bowl, and adjust animal fixed platform, make animal brainpan to be impacted thereon
Portion just contacts with strike ball surface, and compression spring now is nature, and electromagnet is not powered on；Then, electromagnet leads to
Electricity, and electromagnet is adsorbed iron lance afterbody and drives iron lance backward away from the motion of animal direction backward by movable supporting frame
