[0070] The device has a long cylindrical structure. When the device is operated, the holding posture is similar to the holding posture of a pen. The index finger triggers the injection control button 106 to control the operation of the motor assembly 103. The injection control button 106 is a physical button located on the side of the device. It is difficult to control the injection control button 106 by the index finger in the holding posture.

[0071] To solve this problem, the button trigger plate 403 is arranged between the first support plate 401 and the second support plate 402 as the trigger assembly 4. The medical staff indirectly controls the injection control button 106 through the button trigger plate 403. The lever principle is used to achieve sensitive pressing control.
