The handles in the aforementioned two cases all use a large-area hollow structure as the moving track when the handle is pulled out, such as the long slot 222 in Patent Case TW M578668 U and the guide groove in Patent Case TW 201825339 A 253. The aforementioned structural design is likely to cause the mechanical strength of the handle to be reduced, making the rotation process possible to produce deformation, reducing the service life of the quick release; in addition, the pin 30 in the patent case TW M578668 U and the patent case TW The latches 26 in No. 201825339 A are all exposed. They are easily damaged by wind, sun, rain, or accidentally falling off, causing the shaft handle to become unusable. Therefore, it is necessary to solve the aforementioned problems.

In view of this, the object of the present invention is to provide a quick release device for bicycle wheels, which has a longer service life.

In order to achieve the above object, the quick release device for bicycle wheels provided by the present invention includes a quick release lever and a rotating handle. The quick release rod has a rod portion, a head connected to the rod portion, and an axial hole, wherein the head has a receiving groove and two extending grooves, and the two extending grooves are respectively arranged at opposite sides of the receiving groove Two side walls. One end of each extension groove has a blocking portion, and the other end is connected with the axial hole. The rotary handle has a handle body and a pin, wherein the handle body includes a handle head and a handle body with a width smaller than the handle head. The handle can be located in the receiving groove, the handle body is movably located in the axial hole, and one end of the handle is connected to the handle, and a through hole is provided near the other end. The pin is located in the through hole, and its two ends respectively protrude from the opposite surfaces of the handle body. When the handle body moves out of the axial hole, the two parts of the pin protruding from the handle body respectively enter the two extension grooves.

The effect of the present invention is that the rotary handle does not undergo complex process processing, reducing destructive processing so that the rotary handle can maintain good mechanical strength; in addition, the pin is arranged in the quick release rod, which helps to reduce accidental loss of the pin or Possibility of damage.
