In the specific implementation process, the main structures such as the battery, the motor and the like of the device are arranged in the box body 2, so that the device has small volume, is convenient to carry and is convenient to use. However, the shape of the case 2 of the present device is not limited to a rectangle, but may be similar to a pistol, but the internal structure is not changed. The device adopts the rechargeable battery to start the energy source for the motor, and is convenient for the independent use of the device. When the motor of the device is started, a first rotating shaft on the motor drives the turntable 14 to rotate, and one end of a first connecting rod 17 which is rotationally connected with the turntable 14 through a second rotating shaft 15 on the turntable 14 moves along with the turntable 14 in a circular motion. The third rotating shaft 18 on the other end of the first connecting rod 17 is rotatably connected with one end of the second connecting rod 19, the other end of the second connecting rod 19 is provided with a push rod 20, the end part of the push rod 20 is fixedly provided with a piston, and the piston slides in the fixed spray rod 9, so that the spray rod 9 limits the movement directions of the push rod 20 and the second connecting rod 19, and the second connecting rod 19 can only move back and forth in the sliding direction with the piston. Therefore, when one end of the first link 17 moves circularly on the turn table 14, the other end of the first link 17 moves in the moving direction of the spray bar 9 following the second link 19, and the third rotary shaft 18 is kept in rotary connection with the second link 19, in principle similar to the crank link movement. The distance between the second rotation shaft 15 and the first rotation shaft corresponds to the crank of the crank link motion, and when the length of the crank is longer, the radius of the circular motion of one end of the first link 17 is longer, so that the moving stroke of the second link 19 connected with the first link 17 is longer, that is, the longer the movable distance of the piston on the spray rod 9 is, the more anesthetic is sprayed in the spray rod 9. Therefore, the amount of the single shot anesthetic can be adjusted by adjusting the distance of the second rotation shaft 15 from the first rotation shaft. When the rotation speed of the motor is unchanged, the rotation speed of the turntable 14 is unchanged, the reciprocating speed of the piston is unchanged, and the more anesthetic doses are sprayed at a time, the more anesthetic sprays are produced in unit time. The distance between the second rotating shaft 15 and the first rotating shaft can be adjusted by adjusting different disc holes 21 rotatably connected to the rotary table 14 through the second rotating shaft 15, when the distance between the disc hole 21 and the first rotating shaft is the largest, the distance between the second rotating shaft 15 and the first rotating shaft is the largest, and the longer the reciprocating distance between the piston and the spray rod 9 is, the larger the anesthetic spray sprayed from the spray rod 9 is. To facilitate the mounting of the second shaft 15 in a different disc hole 21, the second shaft 15 is detachably connected to the turntable 14. Therefore, further, a clamping block is disposed around one end of the second rotating shaft 15, the second rotating shaft 15 is connected with a limit nut 16 in a threaded manner, the clamping block is located at the back of the turntable 14, and the limit nut 16 is located at the outer side of the first connecting rod 17, which refers to the side facing away from the turntable 14. The second rotating shaft 15 is inserted into the first rod hole of the first connecting rod 17, the second rotating shaft 15 is limited in the turntable 14 and the first connecting rod 17 through the clamping block and the limiting nut 16 and cannot be separated, but the second rotating shaft 15 can rotate in the first rod hole and the disk hole 21. when the distance between the second rotating shaft 15 and the first rotating shaft needs to be adjusted, the limit nut 16 is unscrewed, so that the limit nut 16 is separated from the second rotating shaft 15, the second rotating shaft 15 is taken down, inserted into the disc hole 21 to be placed and the first rod hole, and then the limit nut 16 is screwed, so that the second rotating shaft 15 cannot be separated from the turntable 14 and the first connecting rod 17 and can rotate inside.

When anesthesia spraying is needed, the motor is started, the first rotating shaft rotates, the rotating disc 14, the first connecting rod 17, the second connecting rod 19, the second rotating shaft 15 and the third rotating shaft 18 do crank connecting rod motion, the piston on the push rod 20 connected with the second connecting rod 19 slides back and forth on the spray rod 9, when the piston moves forwards, namely moves towards the joint 10 direction of the spray rod 9, the piston extrudes the space filled with anesthetic in the spray rod 9, the internal pressure is increased, the first one-way valve is opened, the second one-way valve is closed, the anesthetic is sprayed into the spray pipe 11 from the joint 10 on the spray rod 9, anesthesia spraying is formed through the spray head 12 on the spray pipe 11, and the anesthesia spraying is convenient to use for treatment. When the piston moves backward, negative pressure is formed in the spray rod 9, the first one-way valve is closed, the second one-way valve is opened, and anesthetic in the medicine bottle 6 is sucked out from the medicine tube 8 into the spray rod 9 to wait for the next forward movement of the piston. Because the distance between every round trip of the piston is unchanged, the amount of anesthetic sprayed every time is fixed, and the using amount of anesthetic can be controlled by controlling the starting time of the motor. When the part needing anesthesia is smaller and the amount of the anesthesia spray needing to be generated once is smaller, the amount of the anesthesia spray needing to be generated once can be reduced by adjusting the distance between the second rotating shaft 15 and the first rotating shaft, namely the length of the crank, so that waste is avoided.
