This form cannot satisfy According to the needs of different users, the most comfortable use position cannot be presented, so there is a need for improvement.

In addition, a kind of improved traditional bicycle bell is described as follows: please refer to Fig. 1, shown in Fig. 2, it is mainly by the c-shaped fixed plate 11 on the receiving frame 10 and is fixedly locked with the handle by a combination bolt 50, its The structure formed by a bell seat 20 and the bell cover 30 is combined, and the bell receiving frame 10 part is formed by a protruding column 13 structure, which can be used for the bell seat 20, the spring 60 and the bell seat 20. The bell cover 30 is put through, and then a fixing piece 40 is used to extend the through hole 31 placed on the top of the bell cover 30, so that the cylinder 13 that is placed on the receiving frame 10 can be fixed in a combined state, and the top of the bell cover 30 Cover it with a cover plate 70 again, and in addition, on the spring seat 27 on one side of the bell seat 20, a hammer 25 is attached by the connection of the spring 80, so that it is opposite to the outside of the bell cover 30, as a structure for knocking. .

Inheriting the above-mentioned structure, it is provided with an adjustment structure that can do multiple angle transformations. It is a groove 14 with a polygonal shape on the top surface of the bell receiving frame 10, and a bottom end of the bell seat 20 opposite to it. There is a structure in which the polygonal joint part 28 can cooperate with it. In this way, the joint part 28 at the bottom end can be rotated toward the groove 14 of the receiving frame 10 by the pressing action of the external force for the rotation of the bell seat 20. Extrusion makes it obtain different relative positions, thereby changing the angular position of the hammer 25 attached to the bell seat 20.

2. High production cost: due to the complexity of its components and components, the assembly process time is virtually prolonged, reducing the efficiency of the manufacturing process, and the development of molds for various components and the manufacture of semi-finished products result in heavy production costs.

3. The positioning effect of angular rotation is not good: because it is a positioning structure formed by the combination of the polygonal groove of the receiving frame and the bottom end of the bell seat, when the bell seat is rotated and displaced, it is in a polygonal shape. Because there is no elastic space between the junction and the groove, a relatively large external force must be used to perform a relative rotation, which will inevitably cause wear and tear on the contact between the two phases, and under frequent use, it will have a positioning failure. risk.

4. The effect of the hammer action is not good: the hammer is connected to the bell seat by a spring, and the hammer's knocking action on the bell cover is released by the release of potential energy after the spring is compressed and deformed. However, with frequent use or improper external force, the spring will become fatigued and loose, so that it loses its effective elasticity.
