Figure 10 is a top view of a second drug mill of the present invention. Fig. 11 to 12 are schematic views showing the use process of the second drug rolling device of the present invention. As shown in fig. 10 to 12, the second drug grinder 200 of the present invention is different from the first drug grinder 100 in that: since the slider 22 is limited to be unable to move in the X-X ' direction, the through hole 220 of the slider 22 is provided with the internal thread 221, the first connecting rod 33 is provided with the external thread 331, when the handle member 3 rotates around the axial direction of the first connecting rod 33 as the rotating axis, the first connecting rod 33 is displaced in the through hole 220 in the direction parallel to the first direction X, so as to drive the grinding roller 41 to move in the first direction X during the rolling stroke, so that the user can displace in the first direction X and the fourth direction X ' perpendicular to the rolling stroke while the user pushes down the handle connecting rod 30 to cooperate with the guiding of the grinding guide assembly 2 to drive the grinding roller 41 to roll along the rolling stroke (the second direction Y and the fifth direction Y ') on the base plate 1.

When the second end of the handle rod 30 is pressed towards the bottom plate 1, the handle member 3 rotates around the axial direction of the first connecting rod 33 as a rotating axis, and drives the external thread 331 of the first connecting rod 33 to rotate in the internal thread 221 of the through hole 220, and finally drives the first connecting rod 33 to displace integrally in the through hole along the first direction X, and the grinding member 4 has a grinding stroke for grinding the bottom plate 1 along the second direction and dragging towards the first direction.

When the second end of the handle link 30 is released and then restored, the handle member 3 rotates in the opposite direction with the axial direction of the first link 33 as the rotating axis, and drives the external thread 331 of the first link 33 to rotate in the internal thread 221 of the through hole 220, and finally drives the first link 33 to displace in the through hole along a fourth direction X' away from the first direction X, and the grinding member 4 has a grinding stroke for grinding the bottom plate 1 along a fifth direction away from the second direction and dragging towards the fourth direction. The grinding roller 41 of the present invention not only has a simple linear motion, but also has an effect of performing a lateral back-and-forth dragging dynamic grinding while rolling, which is advantageous to more rapidly grind tablets. Other technical features of the second drug grinder 200 are the same as those of the first drug grinder 100, and are not described herein again.

Figure 13 is a schematic view of a third mill of the present invention. Figure 14 is a schematic view of a third mill of the present invention in use. As shown in fig. 13 and 14, the third type of drug crusher 300 of the present invention differs from the first type of drug crusher 100 in that: the milling guide assembly 2 comprises a pair of supporting frames 20 connected to the base plate 1, a second connecting rod 24 and a torsion spring 232 are connected between the supporting frames 20, the second connecting rod 24 and the first connecting rod 33 are kept parallel through a set of connecting rods 25, the first connecting rod 33 has a swinging stroke swinging around the second connecting rod 24, and the torsion spring 232 acts on the second connecting rod 24 and the first connecting rod 33 to press the first connecting rod 33 towards the base plate. The first connecting rod 33, which is movable in the same direction as the direction of movement of the grinding means 4, serves as a movable axis of movement, i.e. as a rotational axis, for the first connecting rod 33. When the second end 30B of the handle link 30 is pressed against the base plate 1, the first link 33 swings about the second link 24, displacing in the second direction from the initial position, increasing the crushing stroke of the grinding member 4; when the second end 30B of the handle link 30 is released and then returned, the first link 33 swings around the second link 24 and stays at the initial position after being blocked. The grinding stroke of the grinding part 4 is only formed by the rotation relative to the first connecting rod 33 and also comprises the displacement formed by the equidirectional movement of the first connecting rod 33, so that the grinding stroke of the grinding part 4 is greatly increased, and the grinding effect is improved. Other technical features of the third drug crusher 300 are the same as those of the first drug crusher 100, and are not described herein again.

Figure 15 is a perspective view of a fourth drug crusher of the present invention. As shown in fig. 15, the fourth drug grinder 400 of the present invention is different from the first drug grinder 100 in that: the milling guide assembly 2 comprises a pair of support frames 20 connected to the bottom plate 1, a mounting cavity 27 serving as an elastic reset piece is arranged at the top of each support frame 20, a torsion spring is arranged in each mounting cavity 27, a second connecting rod 25 is connected between the support frames 20, each support frame 20 is provided with an axial arc-shaped groove 26 surrounding the second connecting rod 25, two ends of each first connecting rod 33 are limited in the corresponding arc-shaped grooves 26, the torsion springs directly act on the first connecting rods 33 and the second connecting rods 25, and the first connecting rods 33 are pressed to the bottom plate along the arc-shaped grooves 26, but not limited thereto.

Figure 16 is a schematic view of a fifth drug crusher of the present invention. As shown in fig. 16, the fifth type of drug grinder 500 of the present invention is different from the first type of drug grinder 100 in that: the grinding element is a grinding plate 42, one side of the grinding plate 42 is pivoted with the roller shaft 34, the other side of the grinding plate is pressed against the surface of the bottom plate 1, and the spring 233 presses the first connecting rod 33 towards the bottom plate 1. When the roller shafts 34 are pressed toward the base plate 1 and moved in parallel, the grinding plates 42 slide on the surface of the base plate 1 following the moving direction of the roller shafts 34. The grinding plate 42 has a grinding stroke for grinding the surface of the soleplate 1 in a second direction Y perpendicular to the first direction X, guided by the grinding guide assembly 2, as the handle member 3 rotates about the first connecting rod 33 as a rotation axis. When the user is using the present invention, the user only needs to press the second end 30B of the handle link 30 towards the base plate 1 to control the movement of the grinding plate 42 along the base plate 1 towards the grinding guide assembly 2, in the process, the grinding plate 42 cooperates with the base plate 1 to form a pair of grinding surfaces, and the spring 233 cooperates with the user's downward force on the handle link 30 to form a pressing force of the grinding plate 42 against the base plate 1, and the user's downward force on the handle link 30 cooperates with the guide of the grinding guide assembly 2 to drive the grinding plate 42 to move along the base plate 1 so as to grind the object to be ground placed on the base plate 1. The cooperation of the grinding plate 42 and the bottom plate 1 can effectively prevent the tablets 5 from rolling, and has a better grinding effect for circular tablets, but not limited thereto. Other technical features of the fifth drug grinder 500 are the same as those of the first drug grinder 100, and are not described herein again.
