[0057] In some embodiments, referring to Figure 1 as shown, the number of threaded rods is two, and the two threaded rods are spaced along the extending direction of the traction member 310, and there is an included angle between the threaded rod and the traction member 310.

[0058] Specifically, two threaded rods are spaced along the extending direction of the traction member 310, and the traction member 310 is connected to the second connecting member 322 on the tractor 100 through the two threaded rods and two nuts, which improves the connection strength between the traction member 310 and the tractor 100. Exemplarily, the distance between the two threaded rods is the same as the distance between the two second connecting members 322, which is 620 mm.

[0059] There is an included angle between the threaded rod and the traction member 310. Exemplarily, the included angle can be an acute angle or a right angle, and the embodiments of the present application do not limit this too much. It should be noted that the included angles between the two threaded rods and the traction member 310 are equal in size, that is, the two threaded rods are arranged in parallel, and the distance between the two second connecting members 322 is the same as the distance between the two threaded rods, so that the two threaded rods correspondingly pass through the through holes 3221 on the two second connecting members 322.

[0060] In some embodiments, referring to Figure 1 and Figure 3 as shown, the number of the first connecting portions 311 is two, the two first connecting portions 311 are symmetrically arranged, and there is a gap between the two first connecting portions 311.

[0061] It can be understood that by providing two first connecting portions 311, the connection strength between the first connecting member 321 and the first connecting portion 311 is improved. There is a gap between the two first connecting portions 311, which provides a placement space for the traction hole 210 of the wheeled diesel generator.

[0062] In some embodiments, referring to Figure 1 as shown, the first connecting member 321 has an abutting end 3211, and the abutting end 3211 abuts against the first connecting portion 311 adjacent to the abutting end 3211.

[0063] It can be understood that by providing the abutting end 3211 on the first connecting member 321, the abutting end 3211 abuts against the adjacent first connecting member 321 to prevent the first connecting member 321 from detaching from the first connecting member 321, which improves the reliability of the first connecting member 321.

[0064] In some embodiments, referring to Figure 1 as shown, the connecting component 320 further includes a limiting member. The first connecting member 321 has a limiting hole 3212. The limiting member is inserted into the limiting hole 3212, and the limiting member abuts against the first connecting portion 311 adjacent to the limiting member.

[0065] Exemplarily, the limiting member can be a pin or other limiting members, and the embodiments of the present application do not impose too many restrictions on this.

[0066] It can be understood that by providing the limiting hole 3212 on the first connecting member 321, a position for inserting the limiting member is provided. The limiting member abuts against the adjacent first connecting portion 311, and the limiting member fixes the first connecting member 321 to prevent the first connecting member 321 from detaching from the first connecting portion 311.

[0067] In some embodiments, referring to Figure 1 as shown, a supporting portion 313 is provided on the towing member 310. The supporting portion 313 connects the first connecting portion 311 and the towing member 310.

[0068] Specifically, the supporting portion 313 is provided below the first connecting portion 311. The supporting portion 313 connects the first connecting portion 311 and the towing member 310, and the supporting portion 313 provides support for the first connecting portion 311, thereby improving the stiffness of the first connecting portion 311.

[0069] In some embodiments, referring to Figure 1 as shown, at least one abutting portion 314 is further provided on the towing member 310. The extending direction of the abutting portion 314 is the same as the extending direction of the towing member 310, and the abutting portion 314 is used to abut against the towing vehicle 100.

[0070] At least one abutting portion 314 is provided on the towing member 310. Exemplarily, the number of the abutting portions 314 can be one or multiple, and the embodiments of the present application do not impose too many restrictions on the number of the abutting portions 314. When there are two abutting portions 314, the distance between the two abutting portions 314 can be 600 mm, and the distance that the abutting portion 314 extends out of the end of the towing member 310 is 75 mm.

[0071] It can be understood that the abutting portion 314 abuts against the towing vehicle 100, which can buffer the force on the contact surface between the towing member 310 and the towing vehicle 100 and slow down the force on the contact surface.

[0072] Exemplarily, the abutting portion 314 can be made of a round iron rod with a diameter of 40 mm.

[0073] Referring to Figure 2As shown in the figure, an embodiment of the present application further provides a tractor 100, which includes a tractor 100 body and a traction device 300 provided on the tractor 100 body.
