After the button 5 is pressed, the control switch is in a closed state, at the moment, the circuit is communicated, and the power supply 6 supplies power to the driving motor 4 through the circuit board 7 so that the driving motor 4 drives the puncture needle bar 2.
Preferably, a booster module 8 is also included, which booster module 8 is electrically connected to the circuit board 7, disposed within the mounting cavity 3. The boost module 8 may adjust the voltage such that the voltage provided by the power supply 6 is more adapted to the operating voltage of the drive motor 4.
As shown in fig. 3 and 4, the puncture device further comprises a safety control 9 connected to the puncture handle 1, and pressing the button 5 can press the button 5 on the safety control 9. The puncture handle 1 is also provided with the safety control 9 which can prevent the button 5 from moving, so that the risk of rotating the puncture needle rod 2 caused by touching the button 5 without puncturing in the operation process can be prevented.
Specifically, the safety control 9 includes a limit guard 91 and a control button 92 connected to one end of the limit guard 91, the control button 92 is slidably connected to the puncture handle 1, the limit guard 91 extends along the radial direction of the button 5, and pressing the control button 92 can move one end of the limit guard 91 to the lower side of the button 5. The safety control 9 further comprises a reset spring 93 sleeved outside the limit baffle 91, one end of the reset spring 93 is fixedly connected to the inner surface of the puncture handle 1, the other end of the reset spring is fixedly connected to the limit block 94, the limit block 94 is fixedly connected to the surface of the limit baffle 91, and when the control button 92 is pressed to enable the end portion of the limit baffle 91 to be located below the button 5, the reset spring 93 is in a stretching state.
When the end of the limit baffle 91 is located below the button 5, the button 5 can interfere with the limit baffle 91 when the button 5 is pressed, so that the button 5 can not be pressed smoothly in this state, and the safety guarantee function is achieved.
