DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-4A tractor comprises a frame 1, a carriage 2 is mounted on the upper side of the frame 1, and the connection method between the frame 1 and the carriage 2 is the prior art, which will not be described in detail herein. A combination plate 3 is provided at the upper end of the right side of the frame 1, and a receiving groove 4 is provided inside the combination plate 3, a threaded rod 5 is connected to the inside of the receiving groove 4 through a bearing, and the other end of the threaded rod 5 extends to the outside of the combination plate 3 and is connected to a rotating rod 10, two groups of threaded sleeves 6 are sleeved on the outer side of the threaded rod 5, and the sides of the threaded sleeves 6 are all connected to connecting plates 7, and two groups of external threads with opposite rotation directions are provided on the outer side of the threaded rod 5, which are not shown in the figure, so when the staff rotates the rotating rod 10 to drive the threaded rod 5 to rotate, the two groups of threaded sleeves 6 can move towards each other inside the receiving groove 4, and a connecting block 8 is connected to the side of the connecting plate 7 away from each other, and a positioning groove adapted to the connecting block 8 is symmetrically provided on the left side of the frame 1.

[0023] Further, see Figure 2 and Figure 3 It can be known that the bottom end of the combined plate 3 is connected to the mounting plate 11, and the interior of the mounting plate 11 is connected to the frame 1 through bolts. Through the cooperation between the mounting plate 11 and the bolts, the connection and disassembly between the combined plate 3 and the frame 1 can be achieved, so that the staff can carry out maintenance work.

[0024] Further, see Figure 3 It can be known that the interior of the accommodating groove 4 is connected with a guide rod 9, and the interior of the connecting plate 7 is provided with a movable groove adapted to the guide rod 9. Through the mutual cooperation of the guide rod 9 and the movable groove, the connecting plate 7 can be guided to meet the horizontal movement requirements of the connecting plate 7.

[0025] Further, see Figure 2 It can be seen that the bottom end of the frame 1 is equidistantly connected with reinforcing rods 15, and the right side of the frame 1 is evenly provided with docking grooves 16. The longitudinal section of the frame 1 is arranged in a Z-shaped structure. When two groups of frames 1 are connected, the reinforcing rods 15 connected to the bottom end of the latter group of frames 1 can be inserted into the docking grooves 16 provided inside the former group of frames 1. By plugging the reinforcing rods 15 into the docking grooves 16, the tightness of the connection between adjacent frames 1 can be further ensured.

[0026] Further, see Figure 4 It can be known that a support plate 12 is connected to the upper side of the combination plate 3, and a positioning rod 13 is inserted into the inside of the support plate 12, and a connecting strip 14 is connected to the top of the positioning rod 13. Limiting grooves that are compatible with the positioning rod 13 are evenly opened inside the rotating rod 10. Through the mutual cooperation of the positioning rod 13 and the support plate 12, the rotating rod 10 that is rotated to the appropriate position can be limited to prevent the rotating rod 10 from shifting due to vibration.

[0027] Further, see Figure 4It can be known that a spring is connected to the lower side of the connecting bar 14 , and the other end of the spring is connected to the support plate 12 . Through the connection of the spring, the limiting effect of the positioning rod 13 on the rotating rod 10 can be ensured.

[0028] Further, see Figure 3 and Figure 4 It can be known that a rectangular piece is connected to the outside of the rotating rod 10, and the rectangular pieces are distributed in a circular array structure on the outer surface of the end of the rotating rod 10. By connecting multiple groups of rectangular pieces, it is convenient for the staff to rotate the rotating rod 10, thereby effectively improving the convenience of using the device.

[0029] Working principle: When the utility model is in use, the staff can first move multiple groups of frames 1 closer to each other according to the loading requirements, and then the combined plate 3 connected to the right side of the frame 1 can be inserted into the left side of another group of frames 1, and then the staff can first pull up the connecting strip 14, so that the positioning rod 13 can be pulled out from the inside of the rotating rod 10. At this time, the staff can rotate the rotating rod 10, thereby driving the threaded rod 5 to rotate at the same time, so that the threaded rod 5 and the threaded sleeve 6 are threadedly matched, so that the threaded sleeve 6 drives the connecting plate 7 to move away from each other in the receiving groove 4, so that the connecting plate 7 connected to the side The block 8 is inserted into the positioning groove provided inside the other group of frames 1, so that the connection operation between adjacent frames 1 can be realized. At this time, the staff can stop pulling up the positioning rod 13, so that the positioning rod 13 is inserted into the inside of the rotating rod 10 to limit the rotating rod 10, and then the staff can repeat the above operation to complete the connection operation between subsequent frames 1. After connecting a suitable number of frames 1, the staff can connect the first group of frames 1 and the front of the tractor to achieve the purpose of one group of fronts towing multiple groups of combined plates 3. The above is the entire working principle of the utility model.
