A screw 4 installed in the upper handle sleeve 2 and above the lower handle sleeve 1, wherein the lower end of the screw 4 is connected with the lower handle sleeve 1 in a screw mode and extends into the lower handle sleeve 1,
The thimble 5 is vertically and slidably arranged in the lower handle sleeve 1, and the lower end of the thimble passes through the balance gland 3;
The pressing block 6 is arranged below the balance pressing cover 3 and is connected with the lower end of the ejector pin 5;
The adjusting spring 7 is arranged between the lower end of the threaded piece 4 and the upper end of the thimble 5 and is connected with the lower end of the threaded piece and the upper end of the thimble 5;
The thimble spring 8 is sleeved on the thimble 5, two ends of the thimble spring 8 are respectively connected with the lower handle sleeve 1 and the balance gland 3,
When the powder pressing force of the powder pressing device is required to be regulated, when the upper handle sleeve 2 is rotated by external force, the upper handle sleeve 2 drives the threaded piece 4 to synchronously rotate, the threaded piece 4 is rotationally connected with the upper handle sleeve 2 and the lower handle sleeve 1, and as the lower handle sleeve 1 is in sliding connection with the thimble 5, the lower handle sleeve 1 cannot synchronously rotate along with the upper handle sleeve 2 and the threaded piece 4, so that when the upper handle sleeve 2 is rotated by external force, the upper handle sleeve 2 and the lower handle sleeve 1 relatively generate axial movement through the threaded piece 4, namely, the upper handle sleeve 2 is lifted relative to the lower handle sleeve 1;
When the upper handle sleeve 2 moves downwards relative to the lower handle sleeve 1, the adjusting spring 7 is compressed;
When the upper sleeve 2 moves upward relative to the lower sleeve 1, the adjusting spring 7 is released.
Referring to fig. 2, when the powder pressing device is in use, the balance gland 3 is placed at the upper end of the edge of the coffee bowl, the upper handle sleeve 2 is pressed downwards by external force, the upper handle sleeve 2 is pushed to push the lower handle sleeve 1 to synchronously move downwards by the screw 4, and the screw 4 compresses the regulating spring 7 downwards;

According to the application, the adjusting spring 7 is used as a transmission part, so that when an external force presses the upper handle sleeve 2, the ejector pin 5 and the pressing block 6 are pushed by the adjusting spring 7 to press the coffee powder, the thrust of the adjusting spring 7 to the pressing block 6 is always the pretightening force of the adjusting spring 7, and the powder pressing device can be used for pressing the coffee powder under constant force; the lower handle sleeve 1 can move downwards relative to the balance gland 3 until the lower end of the lower handle sleeve 1 is propped against the balance gland 3, and the distance between the lower end of the lower handle sleeve 1 and the balance gland 3 is the stroke of the pressing block 6 for pressing the coffee powder, so that the strokes of the pressing powder are consistent each time.
When the upper handle sleeve 2 is rotated, the upper handle sleeve 2 drives the threaded piece 4 to lift, so that the compression degree of the compression spring is adjusted, the pretightening force of the adjusting spring 7 is adjusted, and the powder pressing force is adjusted when the upper handle sleeve 2 is pressed by external force; when the upper handle sleeve 2 moves downwards relative to the lower handle sleeve 1, the adjusting spring 7 is compressed, the critical pretightening force of the adjusting spring 7 is increased, and the compacting force is increased; when the upper sleeve 2 moves upward relative to the lower sleeve 1, the threshold preload of the adjusting spring 7 for releasing the adjusting spring 7 decreases.
In this embodiment, two ends of the thimble spring 8 are respectively connected with the lower handle sleeve 1 and the balance gland 3, which means that: two ends of the thimble spring 8 are in relatively fixed abutting connection with the inner wall of the lower handle sleeve 1 and the balance gland 3; the pretightening force of the adjusting spring 7 is far greater than that of the thimble spring 8.
Referring to the drawings, the upper end of the screw 4 is screw-coupled with the upper handle sleeve 2.
In the application, a plurality of guide grooves 21 are uniformly distributed on the inner wall of the upper handle sleeve 2 at intervals along the circumferential direction, a spring plunger 11 is arranged on the lower handle sleeve 1, the ball head of the spring plunger 11 stretches into the guide grooves 21, and when the upper handle sleeve 2 rotates under the action of external force, the ball head of the spring plunger 11 sequentially moves in the guide grooves 21 along the circumferential direction of the upper handle sleeve 2.
When the upper handle sleeve 2 is rotated by external force, the ball heads of the spring plungers 11 sequentially move in the guide grooves 21 along the circumferential direction of the upper handle sleeve 2, so that collision sound is generated, and the interestingness is improved.
Further, the rotary locking device further comprises a rotary locking piece 9, the middle of the thimble 5 is an outer hexagonal part, the rotary locking piece 9 is provided with a through hole 91 matched with the outer hexagonal part, the outer wall of the rotary locking piece 9 is provided with threads, the inner wall of the lower handle sleeve 1 is provided with internal threads, the rotary locking piece 9 is installed in the lower handle sleeve 1 in a threaded manner, and the thimble 5 penetrates through the through hole 91 and is connected with the pressing block 6.

Referring to fig. 2, the thimble 5 is slidably mounted in the lower sleeve 1 through the rotation stopping member 9, and the resistance at the threaded connection position of the rotation stopping member 9 and the lower sleeve 1 is greater than the resistance at the threaded connection position of the threaded member 4 and the lower sleeve 1, so that when the upper sleeve 2 is rotated by external force, the lower sleeve 1 and the thimble 5 cannot synchronously rotate along with the threaded member 4, and the stability of the powder pressing process is ensured.
In other embodiments, the upper sleeve 2 may be rotated by an external force with one hand, and the lower sleeve 1 may be positioned by the other hand, so as to prevent the lower sleeve 1 from rotating along with the upper sleeve 2.
Preferably, a rotating bearing 10 is coaxially installed at the upper end of the thimble 5, the upper end of the adjusting spring 7 is connected with the screw 4, and the lower end of the adjusting spring 7 is connected with the rotating bearing 10.
