[0041] See also Figure 1 and Figure 2The embodiment of the present application provides a stem 100, comprising a first mounting seat 10 and a second mounting seat 20, wherein the first mounting seat 10 is connected to the second mounting seat 20, and the second mounting seat 20 can be used to install a vertical pole, a head pipe or a front fork, the first mounting seat 10 comprises a joint 11 and a connector 12, the joint 11 can be used to install a handle, the joint 11 is provided with a receiving space 11s, one end of the connector 12 is located in the receiving space 11s, one end of the connector 12 is connected to the joint 11, and the other end of the connector 12 is connected to the second mounting seat 20; the stem 100 also comprises a buffer 30, the buffer 30 is located in the receiving space 11s, and the two ends of the buffer 30 are respectively abutted against one end of the connector 12 and the joint 11. Through the above-mentioned stem 100, when the second mounting seat 20 is subjected to the impact force of the vertical rod, head tube or front fork, the impact force can be transmitted to the connector 12 in the first mounting seat 10. Through the buffering of the buffer 30 between the connector 12 and the joint 11, the impact force transmitted to the joint 11 will be greatly reduced, and then the impact force transmitted to the handle connected to the joint 11 will be greatly reduced, so that the user will be subjected to less impact force when riding, and the user's riding comfort will be improved. In other words, the stem 100 provided by the present application has a shock-absorbing function, and the user experience is good.

[0042] In addition, since the joint 11 is provided with a receiving space 11s, one end of the connector 12 and the buffer 30 are both located in the receiving space 11s, that is, one end of the connector 12, the buffer 30 and the joint 11 share a portion of space, the overall size of the stem 100 is small and has a wide range of applications. Furthermore, since the buffer 30 is located in the receiving space 11s, the receiving space 11s provides protection for the buffer 30, and the buffer 30 is not easily damaged, thereby increasing the overall service life of the stem 100.

[0043] In some embodiments, a limiting groove 121 is provided at one end of the connecting member 12, and the buffer member 30 is provided in the limiting groove 121. By providing the buffer member 30 in the limiting groove 121, when the connecting member 12 is subjected to an impact force, the impact force is buffered by the buffer member 30, and the buffer member 30 is not easily displaced due to vibration, the buffer member 30 has a good buffering effect, and the stem 100 has a good shock absorption effect.

[0044] In some embodiments, the buffer 30 is a spring, and the stem 100 further includes a stopper 40, at least a portion of which is located in the stopper groove 121, and at least a portion of which is located in the inner ring of the spring. By limiting the buffer 30 by the stopper 40, the buffer 30 is less likely to be displaced due to vibration, the buffer 30 has a better buffering effect, and the stem 100 has a better shock absorption effect.

[0045] It is worth noting that the buffer 30 is not limited to a spring, but may also have other forms. For example, the buffer 30 is an object made of rubber material, which is arranged in the receiving space 11s, and its two ends are respectively abutted against one end of the connecting member 12 and the joint 11, and can also buffer the impact force exerted on the connecting member 12, that is, the stem 100 can also have a shock-absorbing function.

[0046] In some embodiments, the stem 100 further includes a shock absorber 50, which is located in the receiving space 11s. The two ends of the shock absorber 50 are respectively in contact with one end of the connector 12 and the joint 11, and the shock absorber 50 and the buffer 30 are arranged on opposite sides of one end of the connector 12. By providing the shock absorber 50, when the second mounting seat 20 is subjected to the impact force of the vertical pole, the head tube or the front fork, the impact force can be transmitted to the connector 12 in the first mounting seat 10. Through the buffering of the buffer 30 between the connector 12 and the joint 11 and the shock absorber 50, the impact force transmitted to the joint 11 will be greatly reduced, and then the impact force transmitted to the handle connected to the joint 11 will be greatly reduced, so that the user will be subjected to less impact force when riding, and the user's riding comfort will be further improved.

By providing the plug 112 and the mounting hole 111a, on the one hand, it is convenient to install the buffer 30 in the receiving space 11s, and on the other hand, when the buffer 30 is damaged, it is also convenient to replace the buffer 30.

[0052] In some embodiments, the buffer 30 is a spring, and the plug 112 is provided with a limiting protrusion 1121, and the limiting protrusion 1121 is located at the inner circle of the spring. The buffer 30 is limited by the limiting protrusion 1121, and when the buffer 30 abuts against the joint 11, it is not easy to shift due to vibration, the buffer 30 has a good shock absorption effect, and the stem 100 has a good shock absorption effect.

[0053] In some embodiments, the plug 112 is screwed to the body 111 at the mounting hole 111 a.
