The connecting member 131 has a mounting portion 131a disposed on the housing 11 and a connecting portion 131b extending transversely from the mounting portion 131a toward the upper half 111 of the housing 11, the collar member 134 is fixedly connected to the connecting portion 131b for the joint section 211 to pass through and the positioning pin 135 to engage, the connecting portion 131b forms two spaced stop pieces 131b1, and the length directions of the stop pieces 131b1 are perpendicular to each other. The flange 132 is fastened to the engaging portion 211 of the frame 21 by a fastening member 132a, such as a screw. The elastic member 133 is a torsion spring and is disposed between the connecting portion 131b and the flange 132. The collar member 134 is recessed to form a pair of first grooves 134a and a pair of second grooves 134b, and the first grooves 134a and the second grooves 134b are staggered and annularly arranged at intervals of 90 degrees. The positioning pin 135 may be, for example, a bolt, but is not limited thereto. The frame 21 and the positioning pin 135 can pivot between a first position and a second position, in the first position, the extending direction of the side section 212 of the frame 21 crosses the extending direction of the base 1, and the positioning pin 135 is engaged with the first groove 134a and abuts against the stop piece 131b1 closer to the installation portion 131a, as shown in fig. 2.

Referring to fig. 5 to 7, the fan head module 3 includes a housing 31 pivotally disposed between the side sections 212 and the horizontal section 213, and a fan blade 32 (see fig. 1) disposed in the housing 31. The housing 31 has two substantially cylindrical connection holes 311 located on two sides, two inner annular surfaces 312 respectively defining the connection holes 311, and two protrusions 313 respectively formed on the inner annular surfaces 312. The frame unit 2 further includes a pair of pivot mechanisms 22 and a pair of engaging sleeves 23 respectively connected to the side sections 212 and two sides of the housing 31 of the fan head module 3. Each pivot mechanism 22 has a pivot head 221 fixedly connected to the side section 212 and pivotally disposed on the housing 31, a positioning element 222 disposed on the inner annular surface 312 of the connecting hole 311 and facing the bump 313, a positioning post 223 disposed on the pivot head 221, and a positioning elastic element 224. The pivot joint 221 has a pivot portion 221a received in the connection hole 311, an engaging portion 221b connected to the pivot portion 221a and extending toward the side section 212, and an inserting protrusion 221c connected to the engaging portion 221b and inserted into the side section 212. The pivot portion 221a has a locking groove 221a1 recessed along the outer circumferential surface and a receiving hole 221a2 recessed radially from the outer circumferential surface. The protrusion 313 is movably received in the slot 221a1 such that the cover 31 can pivot relative to the frame 21 within the spatial range of the slot 221a 1. The positioning post 223 and the positioning elastic piece 224 are both accommodated in the accommodating hole 221a2, and two ends of the positioning elastic piece 224 respectively abut against the positioning post 223 and the bottom surface of the accommodating hole 221a 2. The positioning element 222 has a plurality of positioning holes 222a spaced from each other, and when the cover 31 pivots relative to the pivot joint 221, the positioning posts 223 can be respectively engaged with the corresponding positioning holes 222a by the elastic force exerted by the positioning elastic element 224, as shown in fig. 8. If the user wants to blow the fan head module 3 in different angular directions, the frame 21 is fixed first, and then the fan head module 3 is forced to pivot relative to the side section 212 of the frame 21, so that the positioning posts 223 are engaged with the different positioning holes 222a, so that the angle between the fan head module 3 and the side section 212 of the frame 21 can be fixed, and the fan head module 3 is prevented from pivoting relative to the side section 212 of the frame 21 due to the gravity. Each engaging sleeve 23 has a rear half 231 and a front half 232 for easy assembly and disassembly. The engaging sleeve 23 can cover the joint of the engaging portion 221b and the side section 212, so that the frame 21 and the hinge mechanism 22 can be firmly joined.

As mentioned above, the present invention discloses a pivotally foldable fan, which is upright when in use, and then referring to fig. 9 to fig. 12, if a user wants to store the pivotally foldable fan, the frame 21 pivots relative to the base 1 to pivot the frame 21 and the positioning pin 135 from the first position to the second position, and then the fan head module 3 pivots relative to the side section 212 of the frame 21 to make the extending directions of the base 1, the frame unit 2 and the fan head module 3 parallel to each other.

In summary, the frame unit 2 can pivot relative to the base 1 and the fan head module 3, so that the extending directions of the base 1 and the fan head module 3 are both parallel to the frame unit 2, and the fan is flat, thereby saving space and facilitating storage or transportation.
