In this embodiment, the through hole 15 is disposed on the second mounting portion 12, and the through hole 15 extends in the long axis direction X and is in a long groove shape.

The connecting member 20 includes a plate-shaped connecting portion 21, a first turning portion 22 intersecting with the connecting portion 21 and having a convex shape, and a second turning portion 23 intersecting with the first turning portion 22. The connecting portion 21 intersects with the first turning portion 22 and is generally L-shaped, the second turning portion 23 is columnar and extends along a transverse axis Y perpendicular to the longitudinal axis X, the length of the second turning portion 23 corresponding to the transverse axis Y is not greater than the length of the through hole 15 corresponding to the longitudinal axis X, and the width of the first turning portion 22 corresponding to the transverse axis Y is not greater than the width of the through hole 15 corresponding to the transverse axis Y. In this embodiment, the connecting portion 21 of the connecting member 20 has a first surface 213 opposite to the first side surface 13, an inner end 214 corresponding to one side of the first surface 213 and disposed in the groove 18, and an outer end 215 opposite to the inner end 214 and connected to the frame (not shown), and the first turning portion 22 and the second turning portion 23 are disposed at the inner end 214.

The engaging unit 30 enables the connecting member 20 to be adjusted and positioned along the long axis direction X relative to the supporting member 10, the engaging unit 30 includes a plurality of engaging portions 31 disposed on the second mounting portion 12 of the supporting member 10 and shaped like slots, and an engaging portion 32 disposed on the first surface 213 and shaped like bumps, the engaging portions 31 correspond to the through holes 15 and communicate the first side surface 13 and the second side surface 14, and the engaging portions 31 are spaced along the long axis direction X and intersect with the through holes 15 and shaped like crosses and communicate with each other. The engaging portion 32 is disposed at the inner end 214.

For a further understanding of the invention with the components and the resultant effects, operational advantages, and capabilities thereof, reference is made to the following description, which is believed to provide a further and more thorough understanding of the invention.

As shown in fig. 2 and 3, when the assembly is to be performed, by using the effect that the length of the second turning part 23 corresponding to the transverse axis Y is not greater than the length of the through hole 15 corresponding to the longitudinal axis X, and in the state that the second turning part 23 is substantially parallel to the through hole 15, the second inflection 23 extends from the first side 13 toward the second side 14 through the through hole 15 of the supporting member 10 until the second inflection 23 protrudes from the second side 14, then, the connecting member 20 and the supporting member 10 are relatively rotated by about 90 degrees, so that the second turning part 23 is perpendicular to the long axis direction X (see fig. 3), at this time, the connecting member 20 is disposed obliquely relative to the supporting member 10, and when the first surface 213 approaches the first side 13, the engaging portion 32 can also engage with the corresponding engaging portion 31, so as to engage and combine the connecting member 20 and the supporting member 10 (see fig. 1 and 5).

If it is desired to disassemble, in the state shown in fig. 1 and 5, the outer end 215 of the connecting member 20 is rotated outwards relative to the supporting member 10 (as shown in fig. 4), and the engaging portion 32 is disengaged from the corresponding engaging portion 31, and then the connecting member 20 is rotated by about 90 degrees relative to the supporting member 10, and the state shown in fig. 3 is returned, so that the connecting member 20 and the supporting member 10 can be disassembled.

In the case of fig. 4, after the connecting portion 21 slides along the long axis direction X and the first turning portion 22 slides in the through hole 15, the engaging portion 32 is engaged with the corresponding engaging portion 31, so that the engaging portion 32 is engaged with the engaging portion 31 at different positions, and a length between the first mounting portion 11 and the outer end 215 can be changed, and the vehicle frame can be used with different sizes of vehicle frames and wheels. After the connecting member 20 is adjusted along the long axis direction X relative to the supporting member 10, the inserting and fastening portion 32 and one of the fastening portions 31 are inserted and fastened together, so that the adjusted positioning performance of the soil removing support frame is improved.

It should be noted that the locking portion 31 of the present embodiment is in a shape of a rectangular slot, but may also be in a shape of a slot that is recessed from the first side surface 13 toward the second side surface 14, but does not penetrate through the second side surface 14, which is not shown in the drawings.

In summary, the present invention provides a soil removing support frame with adjustable length, which has a simple structure, is easy to manufacture and assemble, and can achieve the purpose of the present invention.

The present invention has been described in detail in order to enable those skilled in the art to understand the invention and to practice it, and it is not intended to limit the scope of the invention, and all equivalent changes and modifications made according to the spirit of the present invention should be covered by the present invention.
