The relative position of the internally threaded post 60 and the upper housing 30 can be determined by varying the width of the 180 degree spaced 2 internally threaded post recesses 66 and the width of the 180 spaced 2 axially lower bosses 35 on the inside of the upper housing 30.

The 2 screw planes 113 and 2 screw triangular grooves 114 of the 8-shaped surface of the screw 110 are matched with the 2 long rotor middle hole planes 101 and 2 long rotor triangular teeth 102 of the 8-shaped hole of the long rotor 100, so that the screw 110 and the long rotor 100 can synchronously rotate.

The length of the screw thread 111 of the screw 110 is matched with the length of the liquid in the material core, the total length that the screw 110 can push out is the same as the length of the liquid in the material core, when the liquid is used up, the screw 110 cannot push out, the long rotor 100 and the clamping column 120 cannot rotate, and the internally threaded rotary drum 20 cannot rotate when the button 10 is pressed.

The aperture 31 of the upper housing 30 is a dose observation window through which the dose value 41 and the dose scale 42 of the scale drum 40 can be observed, and the dose value 41 of the scale drum 40 pointed by the sharp corner 32 is the dose value of the delivered liquid.

When the internal thread rotary drum 20 is rotated to set the delivered dose, the button 10 synchronously rotates along with the internal thread rotary drum 20, the bidirectional elastic sheet 150 strikes the bidirectional teeth 13 inside the button 10 to sound, and the bidirectional elastic sheet 150 can sound when the internal thread rotary drum 20 rotates clockwise or anticlockwise to increase or reduce the delivered dose.

The lower shell 80 has 2 rings of shell inner annular bosses 82 and 8 elongated bosses 83 in the thicker end. The elongated boss 83 is matched with 2 material cylinder square bosses 73 of the material cylinder 70 to realize circumferential fixation of the lower shell 80, and the annular boss 82 in the shell is matched with 2 material cylinder square bosses 73 of the material cylinder 70 to realize axial fixation of the lower shell 80.

The outer side of the thinner end of the lower casing 80 is provided with a baffle 81. The stop 81 prevents the lower housing 80 from freely rolling when it is mounted on the material drum 70.

The capacity of the material core installed in the material cylinder 70 can be adjusted, and the glass bottle of the material core can be in various capacities by adjusting the parameters of the glass bottle and the rubber stopper thereof, the screw 110, the internal threaded column 60, the upper shell 30 and the lower shell 80.

The circumferential surface of the one-way teeth 51 of the external thread bin 50 is tightly attached to the inner side of the upper shell 30, and the maximum diameter and the maximum number of the one-way teeth 51 are equal to the inner diameter of the upper shell 30, so that the high conveying precision of the device is realized.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
