When the tow pump provided by the utility model is towed on a bumpy road, the tire rim will be subjected to an impact force from the ground, and the impact force is transmitted to the axle assembly as a whole. At this time, the impact force will exert a force on the spiral buffer spring, and under the action of the force, the spiral buffer spring is compressed, that is, at this time, the impact force caused by the uneven ground is buffered by the spiral buffer spring and is not directly transmitted to the frame body, thereby avoiding the failure of the frame body being subjected to additional external force and causing structural cracking.

[0024] Embodiment 1:

[0025] As attached Figure 1 To Attachment Figure 5 As shown:

[0026] The utility model provides a tractor for convenient installation of a pump trailer, comprising a pump trailer 1; a connecting piece 101 is arranged at the front end of the pump trailer 1, the connecting piece 101 is located at the front end of a traction frame 2, the front end of the traction frame 2 is rotatably connected with a rotating seat 205, the inner position of the rotating seat 205 is provided with three mountain-shaped grooves, and the spacing between each two adjacent mountain-shaped grooves is the same, a traction piece 206 is inserted at the inner position of the traction frame 2, and three teeth 207 are arranged on the surface of the traction piece 206, and the three teeth 207 are all passed through the rotating seat 205. In the three mountain-shaped grooves of the seat 205, three limiting holes are opened on the circumferential surface of the rotating seat 205, and the spacing between each three adjacent limiting holes is the same. The three mountain-shaped grooves of the rotating seat 205 and the three limiting holes are staggered. An ear plate 201 is fixedly connected to the upper and lower ends of the rear end of the traction frame 2, respectively. The two ear plates 201 are symmetrically designed, and both ear plates 201 are opened with threaded holes. Bolt members 202 are rotatably connected in the threaded holes of the two ear plates 201, and the bolt members 202 are inserted into the internal position of the connecting member 101.

[0027] Among them, three L frames 203 are fixedly connected to the front end position of the circumference of the traction frame 2, and the three L frames 203 are distributed in a Y shape, and the distance between every two adjacent L frames 203 is the same. A threaded hole is opened at the front end position of the outer side of each L frame 203, and a positioning bolt 204 is rotatably connected in the threaded hole of the L frame 203.

[0028] During use: install and fix the traction member 206 and the traction vehicle, and then plug the traction member 206 into the internal position of the traction frame 2. At this time, the three teeth 207 will pass through the three mountain-shaped grooves of the rotating seat 205 respectively. Next, the rotating seat 205 is rotated, and the three limiting holes of the rotating seat 205 correspond to the three positioning bolts 204 respectively. Then, the three positioning bolts 204 are rotated respectively so that the three positioning bolts 204 are plugged into the three limiting holes of the rotating seat 205, and the position of the rotating seat 205 is limited to prevent the rotation of the rotating seat 205 from causing the three teeth 207 to disengage, causing the traction member 206 to separate from the traction frame 2. This step is easy to install and avoids the situation in which the connecting accessories are easily damaged when the drag pump is towed and connected during the installation and use process.

[0029] Embodiment 2:

[0030] When disassembling the traction frame 2, the bolt member 202 is rotated to remove the bolt member 202 from the inside of the two ear plates 201, thereby breaking the necessary connection between the connecting member 101 and the traction frame 2, and separating the traction frame 2 as a whole.
