The working principle of the embodiment is as follows: when the intravenous injection training device for medical education training is used, as shown in fig. 1-3 and 8, a supporting seat 1 of the device is used for supporting a training arm bottom shell 16 and a training arm top shell 19, vein positions are simulated through a silica gel lining 23 inside the training arm bottom shell 16 and the training arm top shell 19 and a communication groove 24 inside the silica gel lining 23, so that subsequent injection work is facilitated, the problem is solved well because the existing training device cannot change the definition degree of vein vessels on arms, a student cannot adapt to different patients well for injection work, the knob 8 is turned firstly to adjust the illumination intensity of the lamp 18 (it needs to be explained that the driving current intensity is adjusted through the rotation of the knob 8, and then the illumination intensity is changed, which belongs to the prior art), the second rotating shaft 9 is driven to rotate in the rotating process of the knob 8, the third rotating shaft 11 is driven to rotate in the rotating process of the second rotating shaft 9, so that the first bevel gear 12 rotates, the first bevel gear 12 is installed at the front end of the second bevel gear 13 through the fixing rod 15, in conclusion, the second bevel gear 13 and the threaded rod 14 can be driven to rotate through the rotation of the knob 8, in the rotating process of the threaded rod 14, as the threaded rod 14 is in threaded connection with the second lapping block 25, the first lapping block 22, the silica gel bushing 23 and the second lapping block 25 are integrated, so that the silica gel bushing 23 can move up and down under the limiting effect of the limiting rod 21 penetrating through the first lapping block 22 when the threaded rod 14 rotates, the illumination intensity and the lifting of the silica gel bushing 23 can be adjusted according to specific requirements when the rotating in different directions, the silica gel lining 23 can be lifted when the illumination intensity is increased, so that the communicating groove 24 for simulating the blood vessel is clearer, on the contrary, the silica gel lining 23 can be lowered when the illumination intensity is weakened, so that the communicating groove 24 for simulating the blood vessel is not clear any more, and the purpose of adjustment is achieved, it should be noted that the bottom shell 16 and the top shell 19 of the training arm are made of the same material as the silicone lining 23, and are made of semitransparent silicone materials, so that the device can be well matched with the illumination intensity adjusting mechanism in the training process, and the up-and-down movement of the silica gel lining 23 adjusts the definition of the communicating groove 24, thereby achieving better training effect, the device can rotate the rotating plate 5 through the first rotating shaft 4, so as to push out the needle tube 7 in the connecting box 2, and the rubber pad 6 is used for shielding and containing the needle tube 7;

as shown in fig. 1 and 3, after the injection is completed, the inner wall of the silicone liner 23 and the baffle 26 can form a collection area, which can contain the injection agent flowing down in the communicating groove 24, and can judge whether the liquid remains inside the baffle 26, thereby detecting the result of the training, and after the use, the inside of the baffle 26 needs to be cleaned, as shown in fig. 4-7, when the device is used, the components on the needle tube 7 can be adjusted according to the inclined angle required, because the existing device can not well perform the injection training under different inclined angles, the device well solves the problem, firstly, the bubble level gauge 28 inside the external connecting plate 34 is adjusted according to the inclined angle required, and when the adjustment is performed, as shown in fig. 5-7, the crank 33 rotates to enable the fourth rotating shaft 27 to rotate the bubble level gauge 28, the inclination angle of the bubble level gauge 28 is changed, because the bumps 31 and the rubber blocks 32 are corresponding to each other, and the bumps 31 are distributed on the inner side of the disc 30 and the outer side of the ring 29 in a central symmetry manner, and simultaneously, the bumps 31 on the disc 30 and the bumps 31 on the ring 29 are staggered with each other, when the disc 30 rotates a small distance, the bumps 31 on the ring 29 bounce once when the bumps 31 on the disc 30 scratch, so that the device can finely adjust the angle of the whole bubble level gauge 28 on the outer connecting plate 34, after the angle is adjusted, the rubber blocks 32 on the disc 30 and the rubber blocks 32 on the ring 29 are mutually extruded, thereby achieving the positioning effect, the magnetic blocks 20 are used for adsorbing the training arm bottom shell 16 and the training arm top shell 19, and facilitating the subsequent cleaning of the inside of the device, which is the working process of the whole device, and those not described in detail in this specification are well within the skill of those in the art.

Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that various changes in the embodiments and/or modifications of the invention can be made, and equivalents and modifications of some features of the invention can be made without departing from the spirit and scope of the invention.
