Detailed Description

As shown in fig. 1 and fig. 2, the tightening auxiliary wrench of the ball-clamping type bicycle frame clamp of the present invention is installed on a ball-clamping type bicycle frame clamp 100, the ball-clamping type bicycle frame clamp 100 at least includes a ball-clamping portion 11 and a connecting portion 12, the ball-clamping portion 11 corresponds to a ball-clamping seat 21 installed on a bicycle and is clamped and fixed by the ball-clamping portion 11; the connecting portion 12 is assembled on the ball-clamping portion 11 and is disposed opposite to the ball-clamping seat 21 (i.e. away from the vehicle body side), the connecting portion 12 is used for connecting a carriage 31; the technique for the clamping part 11 to clamp the ball-clamping seat 21 can be seen in the structure of the tail end bicycle-carrying rack ball-clamping fixture of taiwan patent I527721 or the structure of the tail end bicycle-carrying rack ball-clamping fixture clamping device of I339168, and the ball-clamping seat 21 can be tightened or loosened by rotating the operation and control assembly 13 above the clamping part 11.

Wherein, the ball-clamping part 11 defines an imaginary X-axis and a Y-axis, the ball-clamping part 11 extends a protruded clamping area 14 along the Y-axis, the clamping area 14 is provided with an adjusting part 141 and the clamping area 14 is provided with a through hole 142, and the through hole 142 is arranged parallel to the X-axis, a T-shaped adjusting part 41 along the Y-axis is assembled in the adjusting part 141; a joint component 42 passing through the through hole 142 of the clamping area 14 along the X-axis direction, and at least one corresponding pad 51 and a fastener 52 disposed on one side of the joint component 42 along the negative X-axis direction, wherein the fastener 52 can be screwed on the joint component 42 to clamp or release the clamping area 14; the fastening member 52 is driven by a tightening auxiliary wrench 60, the tightening auxiliary wrench 60 includes a driving edge 61, a mounting region 62 and a holding region 63, the driving edge 61 is disposed above the mounting region 62 for operating the fastening member 52, a reset module 70 is disposed in the mounting region 62, the reset module 70 includes a gasket 71, an elastic member 72 and a cover 73, the elastic member 72 is disposed between the gasket 71 and the cover 73, the reset module 70 can automatically reset after the driving edge 61 is separated from the fastening member 52 by the elastic member 72, the cover 73 is used as a side against which the elastic member 72 abuts, and the tightening auxiliary wrench 60 is further limited on the holding region 14 without falling off.

Referring to fig. 3 to 7, when the ball clamping portion 11 is assembled to the ball clamping seat 21 through the operation assembly 13 as shown in fig. 3 and 4, as shown in fig. 5 and 6, an assembling person holds the holding area 63 to rotate the tightening auxiliary wrench 60, so that the driving edge 61 of the tightening auxiliary wrench 60 contacts the fastener 52 and operates the fastener 52 to be tightened or loosened, since a rotation dead point is generated when assembling the carriage ball clamping fixture 100, after the assembling person moves the tightening auxiliary wrench 60 away from the side of the clamping area 14 and leaves the rotation dead point, as shown in fig. 7, the assembling person releases the holding area 63, and the driving edge 61 of the tightening auxiliary wrench 60 can be reset and abut against the fastener 52 through the reset module 70, so that the tightening or loosening operation can be performed again.
