[0017] Figure 2 is a top view of a handlebar stem of the present utility model.

[0018] Figure 3 is a schematic structural view of a sheathing part in a handlebar stem of the present utility model. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The following further elaborates and explains the present utility model in conjunction with specific embodiments and the accompanying drawings of the specification:

[0020] Refer to Figures 1 to 3 , a handlebar stem, one end of the handlebar stem is provided with a sheathing part 10 for sleeving a handlebar, the other end of the handlebar stem is provided with a socket part 20 for fixing the handlebar stem, the socket part 20 is provided with a through front fork hole 21, an adapter part 30 is provided between the sheathing part 10 and the socket part 20, a wire routing groove 31 is provided in the adapter part 30, the adapter part 30 is provided with a side wall 32 adjacent to the wire routing groove 31, one end of the wire routing groove 31 extends to the sheathing part 10, a clearance hole 33 is provided on one side of the adapter part 30, and the clearance hole 33 communicates with the wire routing groove 31. The corners of the side wall 32 are provided with rounded corners. The lower end of the socket part 20 is provided with multiple groups of mounting holes 22, and the mounting holes 22 are symmetrically distributed around the front fork hole 21.

[0021] Among them, the cable tube part 10 is used to fix the bicycle handle. The bicycle vertical tube passes through the front fork hole 21 and is fixedly connected to the socket part 20. When routing the wires, the bicycle headset is fixed in the mounting hole 22, and the wire group sequentially passes through the bicycle headset, the clearance hole 33, and finally reaches the wire groove 31 to be connected to the handle on the cable tube part 10. The side wall 32 can form an installation cavity for the wires. The wires are arranged in the cavity, and the corners of the side wall 32 are rounded. When routing the wires, the wires in contact with both ends of the side wall 32 can reduce friction, prevent the wires from being directly damaged by friction, and extend the service life. Among them, the wire group can be a brake wire or a combination of a brake wire and an electric wire. The overall structure is simple, the wire routing is convenient, and a large amount of operation time can be saved.

[0022] The inner wall of the socket part 20 is provided with a relief hole 23. One end of the relief hole 23 is communicated with the wire groove 31, and the other end of the relief hole 23 is communicated with the front fork hole 21.

[0023] Among them, the relief hole 23 can provide appropriate gaps between the various components to ensure smooth movement between the components, reduce wear and interference, and at the same time can also reduce the overall weight of the handlebar tube while maintaining a certain strength and stiffness.

[0024] The cable tube part 10 includes a first clamping block 11 and a second clamping block 12. The first clamping block 11 is fixedly connected to the connecting part 30. The surfaces of the first clamping block 11 and the second clamping block 12 are both provided with fixing holes 13 designed symmetrically up and down.

[0025] Among them, by installing screws in the fixing holes 13, the first clamping block 11 and the second clamping block 12 can be fixed together. When disassembling, the screws on the fixing holes 13 can be loosened, and the first clamping block 11 can be detached, which is convenient for directly taking out the handlebar. The operation is simple and convenient.

[0026] The inner sides of the first clamping block 11 and the second clamping block 12 are provided with a plurality of convex blocks, and the convex blocks can be serrated or triangular.

[0027] Among them, the inner sides of the first clamping block 11 and the second clamping block 12 are provided with a plurality of convex blocks. When installing the handlebar, the convex blocks contact the outer peripheral surface of the handlebar, increasing the friction force and enabling the handlebar to be more firmly installed in the cable tube part 10.

[0028] The socket part 20 includes a first clamping block 24 and a second clamping block 25. The first clamping block 24 and the second clamping block 25 are both provided with fixing holes 13. There is a hollow groove 26 between the first clamping block 24 and the second clamping block 25, and the hollow groove 26 is communicated with the front fork hole 21. The upper end of the side wall 32 is provided with a groove.

[0029] During installation, by twisting the fixing holes 13 on the first clamping block 24 and the second clamping block 25, the effect of fixing the bicycle seat tube can be achieved. Moreover, a hollow groove 26 is provided between the first clamping block 24 and the second clamping block 25, through which the installation effect of the seat tube can be directly observed, facilitating installation and replacement.

[0030] For the seat post disclosed by the present utility model, by providing a wire routing groove 31 that opens downward and a clearance hole 33, the externally connected wire can be directly guided through the clearance hole 33 into the interior of the wire routing groove 31 for wire routing, and the overall operation is simple and convenient.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model, rather than limiting the protection scope of the present utility model. Although the present utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present utility model can be modified or equivalently replaced without departing from the essence and scope of the technical solutions of the present utility model.
