[0039] In the present invention, in order to install the syringe consumables on the device, the syringe push rod is pushed to the front to install the device and syringe together, the device absorbs liquid and removes the gas in the syringe, the device determines how much liquid is inside the syringe, and the depth of needle penetration into the skin is set on the touch screen, and the single injection volume is set. After confirmation, the needle is exposed and the "depth of needle penetration into the skin" is set. The doctor holds the injection pen and inserts it into the subcutaneous tissue, steps on the foot switch, and the injection propulsion motor pushes the syringe for injection.

[0040] The working principle of the above-mentioned fully automatic precision injection system with arm-mounted precise positioning based on flexible shaft transmission is: First, when using this device, first place the device in the working area, then connect the device to an external power source to provide the power required for the device to work; Second, before the injection, the push rod 382 and piston 383 of the syringe 38 and the syringe 381 are installed on the shaft seat 34, and the push rod 381 in the syringe 38 is pushed to the front to install the device syringe 38 together. The device absorbs the liquid and removes the gas in the syringe 38. The device determines how much liquid is inside the syringe 38. The user wears the colloid bracelet 44 on the wrist by himself and wears it on the arm through the motor box 6. The user gently taps the blood vessels on the back of the hand for easy observation. Then the user holds the injection mechanism 3 and the coil seat 43 close to the colloid bracelet 44 and puts the coil into the hand. The coil seat 43 is placed in the groove between the limit blocks 45 on the top of the colloid wristband 44. Then, the coil seat 43 and the micro camera 46 are powered through the cable and the control cabinet 1. As a result, the coil seat 43 is energized and magnetized, and is adsorbed on the colloid wristband 44 and the limit blocks 45. Here, the user adjusts the tilt angle of the injection mechanism 3 by hand, so that the connecting shaft 422 and the mounting plate 423 in the sleeve member 42 rotate accordingly, and the mounting plates 423 of the adjacent units are transformed from a parallel state to an inclined state. Here, the protrusions between the two adjacent sets of concave electric control boxes 424 slide inside the concave electric control boxes 424. Third, the user then powers the coil of the concave electric control box 424 through the control cabinet 1 so that it can absorb the bump inside it, thereby keeping the relative angles between the multiple sets of mounting plates 423 fixed. At this time, the adjustment sleeve 421 and the injection mechanism 3 can present a suitable injection angle with the user's arm under the fixation of the colloid bracelet 44. As the micro-camera 46 on the mounting plate 41 rotates, it can accurately capture image information of the user's arm. Due to the previous user's tapping action to improve the accuracy of the blood vessel position acquisition of the micro-camera 46, the user then The control action of the control cabinet 1 adjusts the position of the coil holder 43 and the injection mechanism 3 on the colloid wristband 44 so that the needle position of the syringe 38 can be relatively aligned with the blood vessel position; the touch screen of the control cabinet 1 here sets the skin penetration depth of the needle of the syringe 38 and the single injection volume. After confirming that the needle is exposed, the "needle penetration depth of the skin" is set. The doctor holds the injection pen and inserts it into the subcutaneous tissue, steps on the foot switch 2, and the motor box 6 pushes the syringe 38 to inject; several injection plans are set on the touch screen of the control cabinet 1, which can be quickly switched through the membrane button on the syringe 38 or on the touch screen; Fourth, the motor 61 is then controlled by the battery 62 and the communication panel 63 in the motor box 6. The motor 61 applies a rotational force to the drive rod 312, thereby driving the reduction gear set 311 to perform a reduction transmission action. Here, the control cabinet 1 controls the power state of the electromagnetic ring 313, so that the drive rod 312 drives the flexible shaft 7 and the connecting cylinder 32 respectively under the drive of the reduction gear set 311 to perform torque transmission. Here, the connecting cylinder 32 drives the screw rods in the depth adjustment component 33 and the injection adjustment component 37 to perform transmission action. The depth adjustment component 33 will drive the shaft seat 34 and the syringe 38 as a whole during the adjustment process. The protective shell of the injection mechanism 3 is extended and penetrated into the muscle of the user; during the adjustment process of the injection adjustment component 37, the injection screw slider in the injection adjustment component 37 drives the syringe 38 to inject the medicine into the human body; after the transmission action is completed, the control cabinet 1 is used to cut off the power to the electromagnetic ring 313 and the electromagnetic pusher 362, so that the electromagnetic ring 313 stops adsorbing the plug-in shaft 314 or the screw of the injection adjustment component 37, so that the transmission force between the two disappears, and under the fast response action of the electromagnetic pusher 362, the blocking block 364 and the limiting ratchet 365 are pushed to perform a blocking action, which can achieve rapid stopping and blocking.

[0041] The present invention provides an arm-mounted, precise positioning, fully automatic precision injection system based on a flexible shaft drive through improvements. By setting an injection mechanism 3 and a wristband mechanism 4, and by setting a deceleration structure and a locking member 36 of a drive adjustment component 31, the injection depth can be precisely controlled, the injection dosage can be precisely controlled, and the positioning block 364 and the limiting ratchet 365 are pushed to perform a positioning action under the fast response action of the electromagnetic pusher 362, which can achieve rapid stopping and positioning. By setting a sleeve member 42, the injection mechanism 3 can present a suitable injection angle with the user's arm under the fixation of the colloid wristband 44.
