[0018] Referring to Figures 1 to 4 As shown, the present utility model provides a portable wall troweling tool, including: a troweling plate 1 and a fixing frame 7. The upper surface of the troweling plate 1 is fixedly connected to a fixing plate 3, and limiting plates 8 are symmetrically connected to the edges of the upper surface of the fixing plate 3. A main sliding groove is formed in the limiting plates 8, and a main slider 9 is slidably connected in the main sliding groove. At the same time, movable grooves 10 are symmetrically formed at both ends of the top of the main sliding groove, and adjusting rods 11 are screwed in the movable grooves 10. The outer side surface of one end of the fixing frame 7 is movably connected to the main slider 9 through a bearing, and the inner side surface of the other end of the fixing frame 7 is movably connected to a handle 4 through a bearing. Auxiliary grooves 6 are symmetrically formed on both sides of the handle 4, and a storage groove is correspondingly formed on the upper surface of the fixing plate 3 at a position corresponding to the handle 4.

[0019] In this embodiment, when the wall troweling tool needs to be used, the wall troweling tool stored in a flat plate state is taken out. Then, the adjusting rod 11 at the end of the limiting plate 8 away from the handle 4 is rotated. The adjusting rod 11 can be disengaged from the screwed hole formed in the main slider 9 through a threaded structure, thereby releasing the restriction between the limiting plate 8 and the main slider 9. The user then pulls the handle 4 upward through the auxiliary groove 6, and the handle 4 can drive the corresponding main slider 9 to move synchronously in the main sliding groove through the fixing frame 7. When the main slider 9 moves from one end of the limiting plate 8 to the other end, the adjusting rod 11 at the end of the limiting plate 8 close to the handle 4 is rotated. The adjusting rod 11 can be inserted into the screwed hole formed in the main slider 9 under the action of the corresponding threaded structure, so as to realize the re-fixation between the limiting plate 8 and the main slider 9. Furthermore, the user can hold the wall troweling tool through the handle 4 to perform corresponding work, improving the practicability of the wall troweling tool in terms of carrying and storage.

[0020] As a preferred implementation mode, the troweling plate 1 is integrally in a frustum-shaped structure, and the cross-section of the inner cavity formed in the troweling plate 1 is in a convex-shaped structure, and the cross-section formed by combining the troweling plate 1 and the inner cavity is in a C-shaped structure.

[0021] In this embodiment, as shown in Figure 1 and Figure 2, the bevel structure at the edge of the trowel plate 1 can effectively reduce the difficulty of using this troweling tool and reduce the probability of the troweling tool scratching the wall surface accidentally. At the same time, the inner cavity of the trowel plate 1 is opened, which can effectively reduce the overall weight of this troweling tool and assist in improving the convenience during carrying.

[0022] As a preferred embodiment, both ends of the inner cavity of the trowel plate 1 are fixedly connected with multiple groups of support rods 2 in parallel at equal intervals through buckles. The support rods 2 are of cylindrical structure, and multiple groups of support plates 5 are fixedly connected in parallel at equal intervals on the lower surface of the fixed plate 3 at the position opposite to the opening of the inner cavity of the trowel plate 1. At the same time, the support plates 5 are of rectangular structure, and the cross-section of the support plate 5 is of T-shaped structure.

[0023] In this embodiment, as Figure 1 and Figure 2 , the settings of the support rods 2 and the support plates 5 can effectively enhance the overall structural strength of the trowel plate 1 and reduce the probability of deformation and damage of the trowel plate 11 during use.

[0024] As a preferred embodiment, the fixed plate 3 is of rectangular structure, the size of the fixed plate 3 is larger than the size of the opening of the inner cavity of the trowel plate 1, and the cross-section formed by the combination of the fixed plate 3 and the support plates 5 is of E-shaped structure. At the same time, the four groups of limit plates 8 fixedly connected to the upper surface of the fixed plate 3 are all of rectangular structure.

[0025] In this embodiment, as Figure 1 、 Figure 2 and Figure 3 , the setting of the fixed plate 3 enables the storage and deployment structure of the handle 4 to be stably arranged on the surface of the trowel plate 1, improving the practicability of this troweling tool and the convenience during carrying, storage and placement.

[0026] As a preferred embodiment, the main chute opened in the limit plate 8 is of long strip structure, and the combination of the limit plate 8 and the main chute forms a square structure. Two groups of movable slots 10 are symmetrically opened at the top of the main chute. The axial cross-sections of the two groups of movable slots 10 are both of middle character structure. At the same time, a threaded structure is opened at the lower opening of the movable slot 10.

[0027] In this embodiment, as Figure 1 、 Figure 3 and Figure 4 , the opening of the main chute can effectively limit the moving range and path of the main slider 9 and the fixed frame 7, thus facilitating the deployment and storage of the handle 4 and the fixed frame 7. At the same time, the movable slots 10 opened at the top of the main chute enable the adjusting rod 11 to move accordingly through the corresponding threaded structure.

[0028] As a preferred embodiment, the cross-section of the main slider 9 is in an I-shaped structure. The dimensions of the main slider 9 and the main chute are adapted to each other. A screw hole is provided on the upper surface of the main slider 9. The adjusting rod 11 screwed in the screw hole is movably connected in the movable slot 10. At the same time, the axial cross-section of the adjusting rod 11 is in a T-shaped structure, and a corresponding thread structure is provided at the lower end of the adjusting rod 11.

[0029] In this embodiment, as Figure 1 , Figure 3 and Figure 4 , the dimensions of the main slider 9 and the main chute are adapted to each other, which can assist in enhancing the stability when the main slider 9 and the fixed frame 7 move, ensuring that the fixed frame 7 and the handle 4 can be normally unfolded and stored. Moreover, the thread structure at the lower end of the adjusting rod 11 corresponds to the thread structure provided at the lower opening of the movable slot 10 and the thread structure in the screw hole provided on the main slider 9, facilitating the movement of the adjusting rod 11 and improving the convenience of fixing and releasing the fixation between the limiting plate 8 and the main slider 9.

[0030] As a preferred embodiment, the fixed frame 7 is in a C-shaped structure. The handle 4 movably connected inside the fixed frame 7 is in a cuboid structure, and the edges of the handle 4 are all in an arc-shaped structure. Two groups of auxiliary slots 6 symmetrically provided on both sides of the handle 4 are both in a long strip structure, and the cross-section of the auxiliary slot 6 is in a right trapezoid structure. At the same time, the fixed frame 7 and the handle 4 together form a rectangular structure.

[0031] In this embodiment, as Figure 1 , Figure 3 and Figure 4 , the provision of the auxiliary slots 6 can reduce the difficulty for the user to lift the handle 4, ensuring that the handle 4 can carry the fixed frame 7 and be smoothly unfolded. At the same time, anti-slip stripes are evenly provided on the surface of the handle 4, and the arc-shaped structure at the edges of the handle 4 can also assist in improving the comfort when the handle 4 is held.

[0032] Through the cooperation of the fixing plate 3, the limiting plate 8, the main slider 9, the fixed frame 7 and the handle 4 of the portable wall plastering tool of the present utility model, the plastering tool can adjust its own structure according to actual needs, and then can be subjected to corresponding storage treatment when being carried or stored, thereby improving the practicality of carrying the plastering tool and also reducing the problem of storage interference between the plastering tool and other tools.
