[0026] See Figures 1-2 , Figures 4-7 The funnel support of this coffee grinder has a positioning cavity 4 on the support 2. Positioning claws 3 are rotatably mounted on both sides of the support 2. A clamping opening 22 for clamping the funnel 1 is formed between the two positioning claws 3. An elastic mechanism is provided between the positioning claws 3 and the support 2. The positioning claws 3 change the size of the clamping opening 22 through the elastic mechanism, so that the support 2 can adapt to funnels 1 of different sizes, such as diameters of 51mm, 58mm, 60mm or 70mm.

[0027] The funnel 1 is positioned and installed on the positioning cavity 4. When the funnel 1 is installed, it is pushed into the positioning cavity 4 along the first direction A, and when it is pushed into the positioning cavity 4, it acts on the positioning claw 3, so that the positioning claw 3 rotates outward. The two positioning claws 3 clamp the funnel 1 on the clamping opening 22 through the elastic mechanism, thereby positioning the funnel 1 on the bracket 2. When the funnel 1 is disassembled, it is pulled out of the positioning cavity 4 along the second direction B, and the two positioning claws 3 rotate inward and reset under the action of the elastic mechanism. When the size of the funnel 1 is large, the angle of outward rotation of the positioning claw 3 after installation in the positioning cavity 4 is large. When the size of the funnel 1 is small, the angle of outward rotation of the positioning claw 3 after installation in the positioning cavity 4 is small.

[0032] One end of the funnel 1 is provided with a second positioning block 9, and the support 2 is provided with an empty slot 10, when the funnel 1 is pushed into the positioning cavity 4, the second positioning block 9 is inserted into the empty slot 10.

[0033] The bottom of the empty slot 10 is provided with a second supporting part 11, after the funnel 1 is pushed into the positioning cavity 4, the bottom of the second positioning block 9 is supported on the second supporting part 11, further preventing the funnel 1 from falling out of the positioning cavity 4 due to gravity, and improving the positioning effect.

[0034] The elastic mechanism includes an elastic member 13, an acting part 12 provided at one end of the positioning claw 3, and a convex column 18 provided on the outer wall of the support 2, the elastic member 13 is sleeved on the convex column 18, and the elastic member 13 is arranged between the acting part 12 and the outer wall of the support 2; the elastic member 13 is a spring, when the positioning claw 3 rotates outward, the elastic member 13 is compressed through the acting part 12, and the two positioning claws 3 clamp the funnel 1 on the clamping opening 22 under the elastic force of the elastic member 13, that is, the funnel 1 is clamped between the inner walls 6 of the two positioning claws 3.

[0035] After the positioning part 16 of the first positioning block 5 slides into the empty hole 8 along the inner wall 6 of the positioning claw 3, at this time the positioning part 16 does not act on the inner wall 6 of the positioning claw 3, and then the positioning claw 3 rotates inward under the elastic force of the elastic member 13 (the rotation angle is small), so that the positioning part 17 of the first positioning block 5 abuts against the inner wall 6 of the positioning claw 3; when the funnel 1 is pulled out of the positioning cavity 4 in the second direction B, the positioning part 16 first acts on the inner wall 6 of the positioning claw 3, so that the positioning claw 3 rotates outward (the rotation angle is small), until the positioning part 16 is away from the inner wall 6 of the positioning claw 3, and then the two positioning claws 3 rotate inward and reset under the elastic force of the elastic member 13.

[0036] The positioning claw 3 is provided with a rotating shaft 14, and the support 2 is provided with a rotating hole 15, the positioning claw 3 is rotatably arranged on the support 2 through the cooperation of the rotating shaft 14 and the rotating hole 15.
