DETAILED DESCRIPTION

[0025] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. Example 1

[0026] like Figure 1 and Figure 2 As shown, the manual bean grinding device for stroke patients of this embodiment includes a base 1, a cylinder 2 disposed on the base 1, and a handle 3 disposed on the top of the cylinder 2.

[0027] The handle 3 adopts a four-bar structure, which is an axisymmetric structure. The four-bar structure includes four connecting rods 31 and pins arranged at four end points. The pin 32 at one end point on the symmetry axis is provided with a square hole along the axial direction, and the other end point on the symmetry axis is provided with a hand-held portion 33 for hand-holding and rotating the handle; the pins at the other two end points are bolts, and a locking nut 34 is threaded on the bolt. By loosening the locking nut 34, the distance between the hand-held portion 33 and the opposite end can be adjusted, thereby adjusting the rotation radius of the handle. Tightening the locking nut 34 locks the rotation radius of the handle.

[0028] Combine Figure 3 and Figure 4 As shown, an upper support portion 25 and a lower support portion 26 are provided in the cylinder 2, and a vertically arranged rotating shaft 22 is also provided in the cylinder 2. The upper and lower ends of the rotating shaft 22 are rotatably connected to the upper support portion 25 and the lower support portion 26 through bearings respectively. An outer disk 23 is also fixed on the lower support portion 26, and an inner disk 24 that cooperates with the outer disk 23 is fixed on the rotating shaft 22.

[0029] A feed port is provided at the top of the cylinder 2, and a top cover 21 is provided at the feed port. A center hole for the rotating shaft to pass through is provided at the center of the top cover 21, forming a ring shape, so that after the top cover 21 is covered, the top cover 21 is sleeved on the rotating shaft 22, and the rotating shaft 22 can be exposed from the cylinder at the center hole for connection with the handle 3. A square rod 221 is provided at the top of the rotating shaft 22 for matching with the square hole of the handle 3. The square rod 221 is inserted into the square hole, and the handle 3 is rotated to drive the rotating shaft 22 to rotate relative to the cylinder 2.

[0030] A storage chamber 27 is formed inside the cylinder 2 between the upper support portion 25 and the lower support portion 26. The upper support portion 25 is provided with a plurality of leakage holes 251 connecting the feed port and the storage chamber 27. A grinding disc gap 28 communicating with the storage chamber 27 is provided between the inner disc 24 and the outer disc 23. A discharge port 261 communicating with the grinding disc gap 28 is provided on the lower support portion 26, thereby forming a material channel from top to bottom. Open the top cover 21, put coffee beans into the feed port, and the coffee beans enter the storage chamber 27 through the leakage holes 251 for storage. Then, close the top cover. The cover 21 is then opened, and the handle 3 is connected to the rotating shaft 22. The handle is turned to perform the magic bean operation. In this embodiment, the width of the grinding disc gap 28 gradually decreases from top to bottom. The width at the entrance of the grinding disc gap 28 is larger than the size of the coffee beans. Therefore, the coffee beans in the storage chamber 27 can enter the grinding disc gap 28. As the rotating shaft 22 rotates, the coffee beans are crushed by the cooperation of the inner disc 24 and the outer disc 23. The coffee bean particles fall along the gradually narrowing grinding disc gap 28, are crushed at the end, and finally enter the discharge port 261.

[0031] A cylindrical discharge chamber 11 is provided on the base 1, and an opening is provided at the top of the discharge chamber 11. The bottom of the cylinder 2 is detachably connected to the opening of the discharge chamber 11, so that the discharge port 261 is connected to the discharge chamber 11, and the crushed coffee beans enter the discharge chamber for storage. The cylinder 2 is removed from the base 1, and the coffee bean particles in the discharge chamber 11 can be taken out.

[0032] In this embodiment, a plug-in portion is provided at the bottom of the cylinder 2, and a receiving portion cooperating with the plug-in portion is provided at the top opening of the discharge cavity 11. The cylinder 2 is connected to the base 1 by inserting the plug-in portion into the receiving portion.

[0033] When using the bean grinding device of this embodiment, the user needs to hold the handheld part and then rotate the handle in a circular motion in the horizontal direction. Therefore, the user can actively perform abduction and adduction movements of the shoulder and elbow joints, achieving multi-dimensional movements of the shoulder and elbow joints. This allows stroke patients to perform occupational activities guided by their interests while also achieving the purpose of exercise. Activities that the patient wants, needs, and is expected to do are carried out centered on the patient's needs, thereby solving the problems of traditional clinical treatment being dull and boring. Example 2

[0034] In this embodiment, an external thread is provided at the bottom of the cylinder 2, and an internal thread that cooperates with the external thread is provided at the top opening of the discharge chamber 11. The cylinder 2 is detachably arranged on the base 1 through the cooperation of the external thread and the internal thread, so that the connection between the cylinder 2 and the base 1 is more stable, and when the handle 3 is turned, the cylinder 2 will not be separated from the base 1.

[0035] The technical solutions of the present invention are not limited to the above embodiments, and any technical solutions obtained by equivalent replacement methods fall within the scope of protection required by the present invention.
