Description of the Invention: [Technical Field] The present invention relates to a clamping insert for use in a clamping device for mounting a transmission to a bicycle frame, and more particularly to a flexible clip for configuring a single piece The use of the inserts allows the transmission clamping device to be adapted to be mounted to a variety of frames. A typical bicycle transmission, particularly a front transmission, is mounted to a seat tube of a bicycle frame by a clamping device. The clamping device may be part of the transmission body or its outer casing, or it may be separate from the outer casing. One of the disadvantages of such clamping devices is that they cannot be applied to a wide variety of bicycle frames, but must be precisely matched to the frame with clamping devices of corresponding diameters. [Prior Art] An adapter is disclosed in the European Patent No. 1 040 99 1 A2 for reducing the clamping diameter of the front derailleur clamping device to conform to the diameter of the bicycle frame tube. The adapter typically includes two embedding locations, each embedding portion having a plastic fastening frame and a metal spacer element. The clamping device includes two arms pivoted together and a fastening frame that is fastened to each arm. The spacer member has an inner surface corresponding to the diameter of the frame tube, and the wall thickness occupies a space between the clamping device and the frame tube. In order to adapt the clamping device to different frame tube diameters, two new spacing elements with comparable new diameters are required. The two new spacer elements must then be embedded in a fastening frame that is placed on the arm of the clamping device. One of the disadvantages of this type of adapter is that it consists of four items: two plastic frames and two aluminum spacer elements, resulting in expensive production and time-consuming installation. Therefore, there is a need for a one-piece clamping insert that is simple to install. 1275526 SUMMARY OF THE INVENTION The present invention describes a single piece clamping insert that is cost effective and easy to install. The clamping insert is configured so that it can be easily and quickly snap fitted to the transmission clamping device without the use of a tool. When mounted on the clamping device, the clamping insert is configured to bias the transmission clamping device in an open or retracted position, allowing the clamping device to be easily placed on the frame tube without scratching the surface of the tube. A typical transmission clamping device includes two clamping arms. One arm is fixedly attached to the transmission and the other arm is pivotally coupled to the transmission. Alternatively, ^ the swing clamp arm can be pivoted directly to the fixed clamp arm. The clamping insert includes a mounting portion, a swinging portion, and a connecting portion to a deflecting portion of the swinging portion. The mounting portion extends generally along the fixed clamping arm. The inner surface of the mounting portion of the clamping insert substantially conforms to the outer contour of the frame tube, and the outer surface of the mounting portion substantially conforms to the inner surface of the fixed clamping arm. The outer surface of the mounting portion preferably includes a mounting guide and an outer edge having at least one attachment end. In order to mount the clamping insert on the fixed clamping arm', insert the mounting guide into one of the recesses or the excavation of the inner surface of the fixed clamping arm, properly aligned along the transmission clamping device Use an insert. The attachment tip is then quickly and rapidly fitted over a portion of the fixed clamp arm (and the outer edge is positioned on an edge). The attachment end, the outer rim and the mounting guide allow the clamping insert to be easily clamped to the transmission clamping device without the use of tools. Further preferably, the mounting portion includes a stop member projecting from the mounting portion, preferably a free end adjacent the mounting portion, the stop member being configured to abut one end of the fixed clamping arm to prevent the clamping insert from being fixed relative to the mounting portion Clamp arm displacement. The oscillating portion of the clamping insert extends generally along the oscillating clamping arm extension 1275526. The oscillating portion preferably includes two fins formed on an outer surface thereof, and the two fins are configured to be received by two corresponding recesses or excavation portions on the inner surface of the oscillating clamping arm to reliably make the oscillating portion Clipped on the swing clamping arm. Preferably, the clamping insert is attached to the transmission clamping device when in its open or retracted position. Preferably, the mounting portion and the swinging portion of the clamping insert have a concave contour and the deflecting portion preferably has a convex or substantially straight contour. The wall thickness of the deflecting portion is thinner than the wall thickness of the mounting portion and the swinging portion, and the thinned deflecting portion effectively forms a flexible hinge therebetween. Preferably, when the clamping insert is mounted on the transmission clamping device, the deflecting portion is substantially aligned with the pivotal connection between the swinging clamping arm and the transmission. Further, the clamping insert preferably forms a C-shaped profile when not attached to the clamping device. The deflecting portion of the reversible outer shape biases the swinging portion of the clamping insert to an open or retracted position, so that when the fasteners for fastening the two clamping arms are released, the clamping insert is spring-swinged and clamped The arm holds the transmission clamp in an open position. Alternatively, a generally straight deflecting portion can also function to deploy the clamping device toward an open position. Alternatively, the inner surface of the clamping insert may be modified to a roughened surface or include an adhesive layer to provide a relatively secure connection between the clamping insert and the frame tube. In another embodiment of the invention, the clamping insert can include two reinforcing inserts disposed in the garment portion and the swing portion. The reinforcing inserts strengthen the clamping insert to resist creep deformation of the plastic portion. The clamping insert is preferably made of plastic, and the reinforcing insert is preferably made of the original and integrated into the clamping insert. These and other features and advantages of the invention will be more fully understood from the description of the appended claims. [Embodiment] Figs. 1, 2, 4, and 5 illustrate a clamping insert 1 according to an embodiment of the present invention.

The clamping insert 1 comprises a dressing portion 2, a swinging portion 4' and a deflecting portion 3 connecting the mounting portion and the swinging portion. The inner surface 18 of the mounting portion 2 substantially conforms to the outer contour of the frame tube, while the outer surface 20 of the mounting portion 2 substantially conforms to the inner surface 22 of the fixed clamping arm n. The outer surface 20 of the mounting portion 2 includes a mounting guide 7 and an outer edge 6 having two attachment ends 5. The outer edge 6 extends radially from an edge 33 of the mounting portion 2. In order to mount the mounting portion 2 on the fixed clamping arm 11, the mounting guide 7 is embedded in a recess or cutout in the inner surface 22 of the fixed clamping arm 11, along which the clamping device is properly aligned. The insert ' is used tightly' and the outer edge 6 and the attachment end 5 are snap-fitted respectively on the edge 3 2 and the portion 3 5 of the fixed clamping arm 1 i .
