[0035] To make the objectives, technical solutions and advantages of this utility model clearer, the utility model will be described in further detail below with reference to the accompanying drawings.

[0036] Referring to Figures 1, 2 and 3, this utility model provides a folding handle, including a drive arm 1, a folding arm 2 and a connector 3. One end of the drive arm 1 is provided with a connector 4 for connecting a drive component, and the other end is hinged to the folding arm 2.

[0037] The drive arm 1 and the folding arm 2 are each provided with a hinge segment for hinged connection, wherein one hinge segment is a fixed connection segment and the other is a movable connection segment. Preferably, the hinge segment provided by the folding arm 2 is a movable connection segment 2a, and the hinge segment provided by the drive arm 1 is a fixed connection segment 1a.

[0038] The movable connecting section 2a is provided with a driving member 5 for driving the connecting member 3 to move towards the fixed connecting section 1a. The connecting member 3 is provided with a limiting space 3a for limiting the relative swing between the movable connecting section 2a and the fixed connecting section 1a. The movable connecting section 2a is inserted into the limiting space 3a so that the connecting member 3 moves along the movable connecting section 2a.

[0039] When the movable connecting section 2a swings to a preset position relative to the fixed connecting section 1a, the driving member 5 drives the connecting member 3 to move toward the fixed connecting section 1a, so that both the fixed connecting section 1a and the movable connecting section 2a are within the limiting space 3a.

[0040] Specifically, the movable connecting section 2a has a notch 21 that matches the fixed connecting section 1a, forming a hinged space for the fixed connecting section 1a to be inserted and swing relative to it. The movable connecting section 2a is hinged to the fixed connecting section 1a via a pivot 22 located at the notch 21. Correspondingly, both the movable connecting section 2a and the fixed connecting section 1a have corresponding pivot holes 21a for the pivot 22 to be inserted. Preferably, the movable connecting section 2a has a rectangular cross-section columnar structure, with the notch 21 at one end. The notch 21 is rectangular. The fixed connecting section 1a has a rectangular cross-section columnar structure, and its width matches the width of the notch 21.

[0041] The driving component 5 includes an elastic element 51 and a linkage element connected to the connecting component 3. The movable connecting section 2a is provided with a mounting hole 22 for mounting the elastic element 51. The linkage element drives the connecting component 3 to move toward the fixed connecting section 1a via the elastic element 51. The elastic element 51 is disposed within the mounting hole 22.

[0042] The linkage includes a guide rod 52 adapted to the mounting hole 22 and a connecting block 53 connected to the connector 3; one end of the guide rod 52 is inserted into the mounting hole 22 to compress the elastic member 51, and the other end of the guide rod 52 is connected to the connecting block 53. Under the elastic drive of the elastic member 51, the connector 3 is always pressed against the fixed connector section 1a, while when the folding arm 2 is in the folded state, the end of the fixed connector section 1a will tilt upward relative to the surface of the movable connector section 2a, thereby preventing the connector 3 from moving along the movable connector section 2a towards the fixed connector section 1a. Accordingly, when it is necessary for the movable connecting section 2a to swing relative to the fixed connecting section 1a to a preset position, the folding arm 2 needs to be unfolded, so that the folding arm 2 and the drive arm 1 form a straight bar. The elastic element 51 drives the connecting member 3 to move along the movable connecting section 2a towards the fixed connecting section 1a, so that both the fixed connecting section 1a and the movable connecting section 2a are within the limiting space 3a, thereby maintaining the straight bar state between the folding arm 2 and the drive arm 1. Preferably, the elastic element 51 is a spring.

[0043] Furthermore, the fixed connection section 1 is provided with a locking hole 11 corresponding to the mounting hole 22, and one end of the guide rod 52 is provided with a locking head 521 adapted to the locking hole 11 for insertion into the locking hole 11;

[0044] When the movable connecting section rotates to a preset position relative to the fixed connecting section, the locking head 521, driven by the elastic member 51, inserts into the locking hole 11. This doubly restricts the relative movement between the movable connecting section 2a and the fixed connecting section 1a.

[0045] Accordingly, the connector 3 is provided with a linkage hole 31 for the insertion of the connecting block 53, and the connecting block 53 is provided with a guide rod connecting hole 531 for the locking head 521 to pass through, so that the connecting block 53 abuts against the guide rod 52. That is, a stepped surface is formed between the end faces of the locking head 521 and the guide rod 52 for pressing against the connecting block 53.

[0046] The connector 4 is provided with a plug 41 for driving the drive component. The plug 41 is provided with a drive hole 411 for inserting the drive component. The cross-sectional shape of the drive hole 411 is non-circular. The non-circular shape can be polygonal, elliptical, etc., which can restrict the drive component from rotating relative to the plug 41 after being inserted into the drive hole 411.

[0047] The folding handle also includes a cover 6. The side wall of the connector 41 is provided with an mounting edge 413. One end of the side wall of the connector 41 is provided with a threaded portion 412 for threaded connection with the connector 4. The connector 4 is provided with a screw hole 42 that is adapted to the threaded portion 412. The cover 6 is provided with a cover hole 61 for the threaded portion 412 to pass through, so that after the connector 41 is connected to the screw hole 42 through the threaded portion 412, the mounting edge 413 clamps the cover 6 with the bottom surface of the connector 4.

[0048] Preferably, the end of the folding arm 2 is provided with a fixed shaft 23 for mounting a handle head, the fixed shaft 23 is provided with a handle head 24 for human hand gripping, and the handle head 24 is provided with a handle head hole 241 adapted to the fixed shaft 23 for mounting on the fixed shaft 23.

[0049] Preferably, the two side walls of the connector 3 are provided with protective parts 32 for assisting the hand to push, and the protective parts 32 have a toothed structure.

[0050] Referring to Figures 4 and 5, this utility model also discloses a coffee grinder, including a folding handle 7 and a grinding device 8. The grinding device 8 is prior art, and it generally includes a grinding head 81 and a drive shaft 82 for driving the grinding head to rotate. The connector 4 is connected to the drive shaft 82 to drive the drive shaft 82 to rotate. The folding handle 7 has the same structure as the corresponding structure shown in Figures 1-3, and will not be described in detail here.

[0051] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
