It has strong operability and reduces the tail speed. The wheel assembly 3 is difficult to install and at the same time it is helpful to improve work efficiency.

In this embodiment, the card slot 3121 is a trapezoidal slot. As shown in FIGS. 10 and 12 , the narrow end of the clamping slot 3121 penetrates the inner side of the external block 312 , so that the clamping slot 3121 can clamp the clamping block 323 to limit the position. In other embodiments, the cross section of the card slot 3121 may also be of other shapes; the shape of the card slot 3121 here is such that it can cooperate with the card block 323 to realize that the card block 323 can only be detached from the card slot by sliding along the extension direction of the card slot 3121 3121 shall prevail.

Further, the clamping block 323 is provided on the inner side of the tail wheel hanger 32, and a relief slot 3231 is provided on the clamping block 323. The extension direction of the relief slot 3231 is parallel to the extension direction of the clamping slot 3121; the axle of the third pulley 314 3141 extends into the clamping slot 3121; when the clamping block 323 is embedded in the clamping slot 3121, the wheel axle 3141 extends into the relief slot 3231. In this embodiment, the relief groove 3231 is used to avoid the wheel axle 3141 and prevent the interference between the slot 3121 and the blocking block 323 and affect the fit; on the other hand, the wheel axle 3141 cooperates with the relief groove 3231 to make the tail wheel hanger 32 and the tail wheel The connection between the connecting pieces is stronger, and at the same time, it can play a certain guiding role in the cooperation between the clamping groove 3121 and the clamping block 323.

Preferably, the clamping block 323 and the tail wheel hanger 32 are integrally formed. Preferably, the external block 312, the main body 311 and the internal block 313 are sequentially distributed and integrally formed.

Further, the third pulley 314 is provided with a rolling groove a3142 along its peripheral ring, and the fourth pulley 322 is provided with a rolling groove b3221 along its peripheral ring; the width of the rolling groove a3142 is greater than the width of the rolling groove b3221, or the rolling groove is The width of b3221 is greater than the width of rolling groove a3142. As shown in Figure 10, in this embodiment, the width of the rolling groove b3221 is greater than the width of the rolling groove a3142. As shown in FIG. 13 , the inconsistent widths of rolling groove b3221 and rolling groove a3142 enable the tail wheel assembly 3 to have a floating gap in the width direction of the slide rail 4 , thereby preventing the pulley damping assembly from getting stuck in the slide rail 4 .
