[0006] The first wheel seat includes a first L-shaped support, a second support and a notch groove, the first support forms a connecting head, the notch groove forms a mounting position, the end surface of the first support facing the notch groove is provided with a groove forming a connecting position, the second wheel seat includes a seat body and a locking tongue extending from the seat body, the seat body is placed in the notch groove and matched with the second support, and the locking tongue is inserted into the groove and fixed.

[0007] The seat body and the second support are correspondingly provided with magnets that attract each other.

[0008] A pulley is arranged outside the second support, and a magnet is arranged on the second support corresponding to the axle position of the pulley. A pulley is arranged outside the seat body, and a magnet is arranged on the seat body corresponding to the axle position of the pulley.

[0009] A first screw hole is provided at the top of the first support, and a machine screw is installed through the first screw to fix it to the locking tongue.

[0010] A second screw hole is arranged on the top of the seat body.

[0011] Positioning stops are provided on both sides of the first support.

[0012] The beneficial effects of the utility model are as follows: the tail wheel is installed on the buffer in a split manner with a first wheel seat and a second wheel seat, so that the tail wheel can install the first wheel seat and the second wheel seat on the guide rail in sequence, reducing the assembly size of the tail wheel installed as a whole on the guide rail, making the installation very convenient, improving the installation efficiency, and also effectively improving the disassembly and assembly efficiency of the tail wheel and the guide rail. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 1 It is a three-dimensional diagram of the detachable tail wheel of the utility model;

[0014] Figure 2 for Figure 1 Exploded view of the detachable body tail wheel shown. DETAILED DESCRIPTION

[0015] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0016] Figure 1 , 2 As shown, in order to reduce the assembly size of the tail wheel and the guide rail, the detachable tail wheel can be disassembled into a first wheel seat 1 and a second wheel seat 2, and the first wheel seat and the second wheel seat are installed on the guide rail in sequence.

[0017] The first support 3, the second support 4 and the notch groove 5 form an L-shaped first wheel seat 1, the first support 3 is used as a connector to be installed on the buffer, the notch groove 5 is used as an installation position to place the seat body 6 of the second wheel seat 2, and the seat body 6 cooperates with the second support 4. A pulley 7 is provided on the outer side of the second support 4, and a magnet 8 is provided on the second support 4 corresponding to the wheel axle position of the pulley 7. A pulley 7 is provided on the outer side of the seat body 6, and a magnet 8 is provided on the seat body 6 corresponding to the wheel axle position of the pulley 7. The seat body 6 and the second support 4 are assembled and positioned by the mutual attraction of the magnet 8. A locking tongue 9 is provided on the mating surface of the seat body 6 and the first support 3, and the locking tongue 9 extends from the seat body 6. A groove 10 is provided on the mating surface of the first support 3 and the seat body 6, and the lock 9 is inserted into the groove 10 as a connection position, and the first screw hole 11 on the top surface of the first support 3 is used to install the machine screw to fix the locking tongue 9, thereby fixing the first wheel seat with the first wheel seat.
