[0024] Therefore, the detailed description of the embodiments of the present utility model provided in the accompanying drawings is not intended to limit the scope of the present utility model to be protected, but merely represents the selected embodiments of the present utility model. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Such as Figure 1As shown, the utility model provides a manual concrete finishing tool which is easy to transport, including a detachable pull rod 10, a folding flat plate 20 and a supporting device 30. Through the deformation and storage properties of the detachable pull rod 10 and the folding flat plate 20, the finishing tool not only has the high efficiency and flatness of traditional finishing tools, but also realizes folding or modularization, so that it can be easily transported and stored when needed, thereby improving construction efficiency, reducing labor intensity, and meeting the diversified needs of modern construction.

[0026] In this embodiment, the detachable pull rod 10 includes a first pull rod 11 and a second pull rod 12 which are detachably connected together, and a main connecting portion 1201 is provided at the bottom of the second pull rod 12, wherein a first docking portion 1101 is provided at the bottom of the first pull rod 11, and a second docking portion 1203 is provided at the top of the second pull rod 12, and the second docking portion 1203 is threadedly connected to the inside of the first docking portion 1101. Construction personnel can choose to install the first pull rod 11 according to actual conditions, which is more flexible.

[0027] In this embodiment, a limiting groove 1202 is provided on the outer surface of the second pull rod 12 , a limiting hole 3104 is provided on the outer surface of the adjustment handle 31 near the top side, and a bolt limiting structure is provided between the limiting hole 3104 and the limiting groove 1202 .

[0028] The limiting groove 1202 includes a longitudinal groove 12021 arranged along the length direction of the second pull rod 12 , and transverse grooves 12022 are arranged at both ends of the longitudinal groove 12021 .

[0029] like Figure 3 As shown, the support device 30 includes an adjustment handle 31, which is movably arranged on the outer surface of the second pull rod 12. Two support rods 32 are arranged on the outer surface of the adjustment handle 31 near the bottom side, and the other end of the support rod 32 is hinged to the second hinge part 2201.

[0030] In this embodiment, the adjustment handle 31 includes a gripping portion 3101, the bottom of the gripping portion 3101 is rotatably connected to a universal ring 3102, the outer side of the universal ring 3102 is symmetrically provided with hinged ears 3103 along the center, one end of the support rod 32 is hinged to the hinged ear 3103, and the other end is provided with a spherical connector 3201, and the spherical connector 3201 is hinged to the second docking portion 1203.

[0031] like Figure 4 As shown, the bolt limiting structure 33 includes a round head screw 3301, the round head part of the round head screw 3301 is arranged in the limiting groove 1202, the round head screw 3301 passes through the limiting hole 3104 from the inside of the second pull rod 12, and is provided with a fastening nut 3302, and an arc-shaped gasket 3303 is arranged between the fastening nut 3302 and the adjustment handle 31.

[0032] Specifically, when the folding flat plate 20 needs to be unfolded, first rotate and move the holding part 3101 to move the round head screw 3301 from the top transverse groove 12022 to the bottom transverse groove 12022. During this process, the support rod 32 will cause the two flattening sub-plates 22 to contact and unfold. When it needs to be recovered, rotate and move the holding part 3101 again to recover the folding flat plate 20.

[0033] like Figure 2 As shown, the folding flat plate 20 includes a flat main plate 21, a first hinge portion 2101 is arranged on the top of the flat main plate 21, flat sub-plates 22 are hinged on both sides of the flat main plate 21, a second hinge portion 2201 is arranged on the top of the flat sub-plate 22, and the main connecting portion 1201 is hinged to the first hinge portion 2101.

[0034] In this embodiment, docking joints a2102 are provided on both sides of the flattening main board 21 near the bottom, and docking joints b2202 are provided at the flattening sub-board 22 opposite to the docking joints a2102. When the flattening sub-board 22 and the flattening main board 21 are in the same plane, the docking joints a2102 and the docking joints b2202 conflict with each other. By adding docking joints, it is avoided that the gap at the hinge of the folded flattening board 20 cannot form the same plane when it is unfolded.

[0035] As a preferred embodiment, during the dough collection process, the angle between the detachable pull rod 10 and the folding flat plate 20 is preferably between 30 degrees and 70 degrees. This angle can better ensure the support of the folding flat plate 20 by the supporting device 30 and better force.

[0036] Specifically, the working principle of this kind of manual concrete finishing tool which is easy to transport is as follows: when it needs to be unfolded, rotate and move the holding part 3101 to move the round head screw 3301 from the top transverse groove 12022 to the bottom transverse groove 12022. In this process, the support rod 32 will cause the two leveling sub-plates 22 to collide and unfold. At this time, the docking joint a2102 and the docking joint b2202 collide. The folding leveling plate 20 is unfolded and the finishing construction can be started. At the same time, the first pull rod 11 can be added to the top of the second pull rod 12 as needed. When recycling, rotate and move the holding part 3101 again to recycle the folding leveling plate 20. Through the above structure, the problem that large-size finishing tools occupy a large amount of storage space on construction sites with complex environments and limited space, and are easily damaged during transportation and movement, and even affect the construction progress is solved.

[0037] The above further describes the present utility model by means of specific embodiments. However, it should be understood that this specific description should not be construed as a limitation on the essence and scope of the present utility model. Various modifications made by those of ordinary skill in the art to the above embodiments after reading this specification all fall within the scope protected by the present utility model.
