umbrella frame 5 has ahinge 500 on the top, thehinge 500 has a connectingportion 501, the connectingportion 501 is formed with aninserting portion 502 capable of rotatably connecting to thecross rod 3, and the top end of theinternal tube 9 passes through the top end of thecross rod 3 and is inserted into the connectingportion 501, multiple third connectingholes 503 are respectively formed on the top end of theinternal tube 9 and the connectingportion 501, eachthird pins 503 passes through the corresponding third connectingholes 503 to connect the top end of theinternal tube 9 to the connectingportion 501, that is, if thehinge 500 is rotated along the circumferential direction of theinternal tube 9 by a hand, theinternal tube 9 and thehinge 500 will be rotated simultaneously, while thecross rod 3 is not rotated. - When in use of the umbrella in this embodiment, a right hand holds the
handle 400 and then pulls thehandle 400 downward along the axis of thecross rod 3, and the lower toothedcylindrical clutch 72 is driven to compress thespring 73 and move downward, so that the looped teeth of the lower toothedcylindrical clutch 72 is separated from the looped teeth of the upper toothedcylindrical clutch 71. At this time, the upper toothedcylindrical clutch 71 may rotate around thecross rod 3, and then theumbrella frame 5 is stirred by a left hand and then allowed to rotate left and right along with theinternal tube 9 and the upper toothedcylindrical clutch 71. After the shading angle is adjusted, the right hand is released, the lower toothedcylindrical clutch 72 moves upward for restoring under the action of thereset spring 73 and to engage the upper toothedcylindrical clutch 71 again. Therefore, the operation is very convenient. - The differences between this embodiment and Embodiment 1 lie in that: as shown in
FIG. 6 ,FIG. 7 andFIG. 8 , the connectingportion 501 of thehinge 500 is not directly connected to the top end of thecross rod 3, but is fixedly connected to theinternal tube 9; meanwhile, the top end of thecross rod 3 is rotatably provided with asecond collar 600, thesecond collar 600 has a second insertingportion 601 rotatably inserted into thecross rod 3, mutiple fourth connectingholes 602 are respectively formed on thesecond collar 600 and theinternal tube 9, eachfourth pin 603 passes through the corresponding fourth connectingholes 602 to connect thesecond collar 600 to theinternal tube 9. - The differences between this embodiment and Embodiment 1 lie in that: as shown in
FIG. 9 , the adjusting mechanism in this embodiment is different from that in Embodiment 1, and theadjusting mechanism 7 a in this embodiment comprises anupper clutch 71 a and alower clutch 72 a; thecross rod 3 is sleeved outside of thebottom joint 8 and fixed, theinternal tube 9 is rotatably disposed inside thecross rod 3, and the bottom end of theinternal tube 9 is connected to theupper clutch 71 a; theupper clutch 71 a and thelower clutch 72 a are disposed inside thecross rod 3, thelower clutch 72 a is connected to the front of thebottom joint 8, and theupper clutch 71 a is rotatably connected to the front end of thelower clutch 72 a; thelower clutch 72 a has a front surface, the front surface is alternately provided withmultiple positioning holes 721 a in circumferential direction, correspondingly, theupper clutch 71 a has an bottom surface, the bottom surface is provided with a plurality ofelastic pins 711 a, thepositioning holes 721 a receives theelastic pins 711 a. When in use, rotate theumbrella frame 5 of the top end of thecross rod 3 to drive theinternal tube 9 to rotate, and thus drives theupper clutch 71 a connected to theinternal tube 9 to rotate. After the proper shading angle is adjusted, theumbrella frame 5 is stopped rotating, and theelastic pins 711 a on theupper clutch 71 a are inserted into thecorresponding positioning holes 721 a for positioning. To ensure the stable rotation between theupper clutch 71 a and thelower clutch 72 a, and avoid the disengagement between theupper clutch 71 a and thelower clutch 72 a, the center of the front surface of thelower clutch 72 is depressed inward to form aslot 722 a, and correspondingly, the middle of the bottom surface of theupper clutch 71 a extends backward to form anextension 712 a matching with theslot 722 a; there are twoelastic pins 711 a, and the twoelastic pins 711 a are symmetrically distributed on the bottom surface of theupper clutch 71 a.
