The cap 2 also has two shaft pins 20, 21 projecting up and down from the left side to fit in two pin holes 106 in the left side of the entrance 100 so that the cap 2 can swing open with the shaft pins 20, 21 as pivots. 
     The grinding plate 3 is rectangular shaped to fit in the sliding cell 11, having grinding teeth 30 for grinding grain pepper on a right upper side (as viewed in FIG. 2) and a block 31 extending downwardly therefrom. 
     The spring housing 4 is fitted in the sliding cell 11 under the grinding plate 3 and a spring 7 is placed in the spring housing 4. The block 31 of the grinding plate 3 extends into the spring housing 4, contacting and pushing against the left end of the spring 7 which has its opposite end bearing against the wall of the spring housing 4. 
     The grinding block 5 is provided to fit in the space between the separating plates 104 and 105 and has a sloped grinding portion 51. 
     The adjusting rod 6 is provided to fit horizontally in the three semi-circular grooves 116, 107, 108 in the separating plates 103, 104, 105, and has a shaft portion 60 to fit in the semi-circular groove 108, a middle eccentric portion 61 to fit through the through hole 50 in the grinding block 5 and also to fit in the semi-circular groove 107, a right cone-shaped position portion 62 provided with a plurality of shallow holes 620 in an edge portion to correspondingly fit with the projection 109 on the semi-circular groove 106 and a turning button 63 extending from the cone-shaped position portion 62. 
     The trigger 8 is provided under the left end (as viewed in FIG. 2) of the sliding cell 11 and within the trigger guard 12, having a top pushing portion 80 to contact and push the end of the grinding plate 3, two shaft rods 81, 82 extending from both sides under the pushing portion 80 to fit in two shaft holes 111, enabling the trigger 8 to be pulled back by a finger to rotate with the shaft rods 81, 82 as pivots. 
     A cap unit 9 is provided to cover an opening 130 in the lower end of the lower chamber 13, consisting of an inner cap 90 and an outer cap 91. The inner cap 90 fits in guide rails 131 of the opening 130, having through holes 900 for a seasoning, such as salt, stored in the lower chamber 13 and two ridges 901, 902 to engage with two slots 911, 912 in the outer cap 91 so that the outer and the inner cap can be combined together firmly. 
     In assembling this grinder, at first the pins 20, 21 of the cap 2 are fitted in the pin holes 106 in both half housings 1, and the shafts 81, 82 of the trigger 8 are fitted in the shaft holes 111 in both half housings 1. Next, the spring 7 is placed in the spring housing 4, and the block 31 in the grinding plate 3 is inserted in the left portion of the spring housing 4, the spring 7 pinched between the black 31 and the vertical right wall of the spring housing 4. Then the grinding plate 3, together with the spring housing 4, is placed in the sliding cell 11, letting the grinding teeth 30 extending out of the sliding cell opening 110 and positioning the spring housing 4 under the sliding cell 11. After that, the adjusting rod 6 is inserted through the through hole 50 in the grinding block 5, and the adjusting rod 6 together with the grinding block 5 is placed in the three separating plates 103, 104, 105, with the grinding block 5 fitting between the inner and the middle plates 104, 105, with the shaft portion 60 of the adjusting rod 6 fitting in the semicircular groove 108 in the inner separating plate 105, with the cone-shaped position portion 62 fitting between the middle and the outer separating plate 104, 103, with the turning button 63 positioned outside of the outer separating plate 103, and with one of the shallow holes 620 of the position portion 62 fitting with the projection 109 on the semi-circular groove 116 in the outer separating plate 103. Then the upper and the lower half housings 1 are combined together, fitting pins 14 in the corresponding pin holes 15. And lastly, the cap unit 90 is placed on the opening 130 at the lower end of the lower chamber 13, by placing the inner cap 90 between the guide rails 131 and then sliding the outer cap 91 in the sliding grooves 132 from the right to the left (as viewed in FIG. 2) and covering the inner cap 90 and then fitting the ridges 901, 902 with the slots 911, 912 to combine both the inner and the outer caps 90, 91 together. 
     In using this grinder, the cap 2 has to be pulled to swing open before grain pepper is filled through the opening 100 into the chamber 10. Then the trigger 8 is pulled back, letting the pushing portion 80 push the grinding plate 3 rightward so that the grain pepper positioned in the space between the teeth 30 and the sloped grinding face 51 of the grinding block 5 can be ground. If the trigger 8 is released after having been pulled, the grinding plate 3 can be pushed back to its original position by the elasticity of the spring 7 in the spring housing 4 and then the trigger 8 is returned to its original position by the plate 3. Repeated pulling and releasing movement of the trigger can grind the grain pepper in the chamber 10 into powder pepper, which then falls out of an exit 102 in the lower end of the chamber 10. 
     If the size of ground powder pepper is to be adjusted, the turning button 63 is turned to rotate the adjusting rod 6, and the eccentric portion 61 can rotate to move the grinding block 5 down and thus the space between the sloped grinding face 51 and the teeth portion 30 of the grinding plate 3 can be made narrower to diminish the size of the ground powder pepper. 
     The adjusting rod 6 is kept stabilized by the fitting engagement of the projection 109 on the semi-circular groove 116 in the outer separating plate 103, said rod 6 cannot move during grinding action. 
     The lower chamber 13 can be used for storing a different kind of seasoning such as salt, etc., which can be shaken out thereof by pushing rightward the outer cap 91 to expose the holes 900 in the inner cap 90 and the contents can be shaken out of said holes 900.
