Adjustable angle quick release handle

The invention belongs to an adjustable angle quick release handle, in particular, when a quick release mandrel is pressed, the quick release handle can still be pulled out to the outside to adjust the angle of the rotary handle, so that the handle is pulled Avoid the front fork of the bicycle or the rear fork of the bicycle, and when the lever is pulled outward to pull the rotation angle to drive the quick release mandrel, the quick release spindle and the nut can be locked tightly to eliminate the quick release grip tightening. Incomplete situation.

The quick-release handle that is used in combination with the front fork or the rear fork of the bicycle is required to first push the trigger handle away from the quick release spindle to relax in a straight line, and rotate the quick release handle to drive the quick release spindle rotation. Press the nut tightly and tighten the nut after the quick release mandrel, and press the trigger handle at an angle to the quick release mandrel, but the quick release handle of the handle will rotate and push the card tightly. During the system, sometimes it is blocked by the bicycle front fork or the bicycle rear fork, and the trigger handle cannot be pushed and locked at an angle with the quick release mandrel. The push handle needs to be pushed open and the quick release mandrel is in line. Rotate the angle to relax the quick release mandrel, let the trigger handle flash over the bicycle front fork pipe diameter or the bicycle rear fork pipe diameter, and clamp at an angle with the quick release mandrel, and rotate at an angle to relax the quick release. The shaft is then fastened and the handle is clamped, which will cause the quick release of the mandrel to be tight and incomplete, which will affect the safety of the bicycle rider.

In view of this, the inventors have directed the aforementioned prior quick release grips. The problems faced were discussed in depth, and through years of experience in research and development and manufacturing of related industries, and actively seeking solutions, after long-term research and development, we finally succeeded in developing a quick-release handle with adjustable angles. In order to overcome the shortcomings of the existing quick release grip, the purpose of the full quick release can not be achieved, and the quick release grip is more practical and meets the needs of the user.

The main object of the present invention is to provide an adjustable angle quick release handle, so that when the quick release mandrel attached to the bicycle is tightened, the quick release handle can still pull out the rotation adjustment trigger handle angle to the outside. The trigger handle of the quick release handle flashes over the bicycle front fork pipe diameter or the bicycle rear fork pipe diameter, and when the quick release handle is pulled outward to adjust the angle of the adjustment handle, the steel ball is forced to drive the quick release mandrel to rotate. Tighten the quick release mandrel to eliminate the incomplete rotation of the quick release mandrel.

To this end, the present invention mainly implements the various objects and effects of the invention through the following technical means. The quick-release handle of the adjustable angle has a quick-release mandrel which is a hollow rod of an appropriate length, and is quickly disassembled. One side of the mandrel is provided with an adjusting screw seat and a quick release handle, and the other side is provided with a nut. The adjustable angle quick release handle has a structure including: a quick release handle, a pull handle spindle, and a Quickly disassembling the mandrel, a plurality of steel balls and springs, a return spring, an adjusting screw seat and a nut, the quick release grip is a handle that can be rotated and pulled out to adjust the rotation, and the front end of the quick release grip is provided There is a sphere, a groove is arranged through the sphere at the middle of the sphere, an eccentric hole is arranged through the sphere and the groove on the side of the sphere, and a shank is arranged on the bottom side of the sphere, and a pivot rod is arranged in the eccentric hole, and the front side of the pivot rod a screw hole is provided, and the screw hole can be screwed to the front end thread of the shaft of the pull handle spindle, The front end of the pull mandrel is provided with a shaft, the front end of the shaft is provided with a thread, a convex diameter is arranged at the middle of the pull mandrel, and a convex ring is arranged at the rear end, and the upper ring of the convex diameter is provided with a plurality of grooves, and the front side of the groove is relatively Deep deep groove, shallow groove on the back side, the quick release mandrel is a suitable length of the hollow pipe body, the outer diameter of the rear end of the hollow pipe body is provided with external thread, and the external thread locks the intrinsic nut A through hole is formed in the center of the hollow pipe body from the rear end to the front end through the quick release mandrel. When the through hole extends to the front end, the reduced aperture forms a shrinkage hole, and the shrinkage hole and the through hole form a spring. Retaining edge, when the shrinkage hole extends to the front end, the aperture is again reduced to form a perforation, and the front end of the quick release mandrel has a slightly larger outer diameter fastening head, so that the rear end of the fastening head and the smaller outer diameter of the air permeability tube The body joint forms a locating seat retaining edge, and a plurality of steel ball holes are arranged at the outer diameter of the fastening head, the steel ball hole penetrates into the shrinkage hole, the steel ball hole contains a steel ball and a spring, and the mandrel pull handle is worn with a return spring The utility model is disposed in the through hole, so that the convex diameter of the mandrel handle is received in the shrinkage hole, and the shaft rod is pierced by the through hole and screwed to the pivot rod In the hole, the return spring is accommodated between the convex ring and the spring retaining edge, and the adjusting screw seat is disposed on the retaining edge of the fixing head positioning seat, and the adjusting cover and the pressing pad are arranged on the front side of the adjusting screw seat, and the center of the adjusting screw seat is arranged There is a through hole, a groove is arranged in the center of the front side, an internal thread is arranged in the groove, and a pressing pad is arranged on the front side of the adjusting cover, and a through hole is arranged at the center of the adjusting cover and the pressing pad, and the adjusting cover is provided The bottom side is provided with an external thread and is screwed onto the internal thread.

Therefore, when the quick release mandrel is pressed, the quick release handle can still pull out the angle of the rotation adjustment trigger handle to the outside, so that the trigger handle avoids the bicycle front fork or the bicycle rear fork, and the handle is pulled When pulling out the rotation angle to the outside to drive the quick release mandrel, the quick release mandrel and the nut can be locked tightly to eliminate the incomplete tightening of the quick release handle, and the internal thread in the adjustment screw groove , and adjust the outer thread on the bottom side of the cover, screw or screw The looseness can be adjusted to loosen the quick release grip to the outside.
