[0052] The linear motor 3 is arranged in the handle 2, which is used to drive the syringe 1 to perform an injection action so that the colloid stored in the syringe 1 is discharged from the needle end thereof. This discharging method does not require the dispensing machine to be additionally equipped with an air pressure system, has good portability, and the use distance is not limited by cables. It has good flexibility in use and is also convenient for more precise control of the amount of glue discharged.

[0053] Furthermore, the linear motor 3 is powered by a rechargeable battery 4, such as a lithium battery, wherein Figure 5 As shown, the battery 4 is arranged inside the handle 2; the linear motor 3 is started and stopped by the function button 5, wherein, as shown in FIG. Figure 3 As shown, the function button 5 is arranged on the side of the handle 2.

[0054] In the above structure, the linear motor 3 includes a lead screw 31 , a slider 32 , a guide rod 33 and a motor 34 .

[0055] Among them, the screw 31 is arranged inside the handle 2 to rotate vertically, and the screw 31 passes through the slider 32 and is screwed, and the slider 32 selectively presses downward against the upper end of the syringe 1; the motor 34 is fixed inside the handle 2, and the output end of the motor 34 is fixedly connected to the upper end of the screw 31. When the motor 34 is working, its output end drives the screw 31 to rotate, and then the screw 31 drives the slider 32 to rise and fall. When the slider 32 descends, the slider 32 presses down the pressing end of the upper end of the syringe 1, driving the syringe 1 to perform the injection action.

[0056] The guide rod 33 is used to guide the slider 32 when it is raised or lowered, wherein the guide rod 33 is fixedly arranged inside the handle 2 along the vertical direction, and the guide rod 33 passes through the slider 32 and is slidably connected.

[0057] In the above structure, the syringe 1 includes a barrel 11 , a rubber piston 12 , a piston rod 13 and an injection needle 14 .
