[0036] 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 the embodiments.

[0037] Reference Figure 1-10 A curved plastering trowel with adjustable curvature comprises: a curved blade 1, a vertical rod 2 located in the middle of the curved blade 1, a handle 3 arranged at the top of the vertical rod 2, and a telescopic rod 4 with both ends hinged to the vertical rod 2 and the curved blade 1 respectively.

[0038] Among them, the curved blade 1 is made of high-toughness steel, which can realize free adjustment of the curvature without breaking; the handle 3 is made of solid wood, which has a good grip and is connected to the curved blade 1 through the vertical pole 2; the telescopic rod 4 can adjust the length, and then adjust the curvature of the blade.

[0039] Specifically, perforated plates are respectively provided on both sides of the vertical pole 2 and near the edge of the arc-shaped blade surface 1 to form mounting positions; both ends of the telescopic rod 4 are rotatably assembled with the perforated plates for telescopic adjustment.

[0040] Preferably, the telescopic rod 4 includes: a central threaded sleeve 41, and screws 42 assembled at both ends thereof; accordingly, an open plate is provided at the end of the screw 42, through which bolts, pins, etc. are passed to assemble it with the vertical rod 2 and the curved blade 1.

[0041] In addition, a multi-ribbed sleeve is provided on the outside of the central threaded sleeve 41 to facilitate operation thereof.

[0042] It is understandable that the threads of the screw rod 42 and the central threaded sleeve 41 are adapted so that when the central threaded sleeve 41 is adjusted and rotated, the screw rods 42 at both ends are screwed in or out synchronously to achieve a change in the overall length.

[0043] It should be noted that there is one upright pole 2 or a plurality of upright poles 2 are symmetrically arranged.

[0044] like Figure 1 As shown, two vertical poles 2 are provided, and telescopic rods 4 are provided respectively; similarly, only one vertical pole 2 can be provided at the center position, but the corresponding adjustment force on the curved blade surface 1 will be weaker. The number and position of the vertical poles 2 can be selected in combination with the size of the curved blade surface 1.

[0045] In some embodiments, the four corners of the arc-shaped blade surface 1 are configured as arc-shaped chamfers.

[0046] In some embodiments, it also includes: a plurality of shaping strips 5 set to specific curvature specifications.

[0047] Correspondingly, the shaping strip 5 is clamped on the outer side of the arc-shaped blade surface 1 to better limit and adjust the shape of the arc-shaped blade surface 1.

[0048] like Figure 6 、 8 ~ 10; the middle position of the arc-shaped blade 1 is provided with an intermediate reinforcement strip 6 along its axial direction; at the same time, bayonet 61 is provided at both ends of the intermediate reinforcement strip 6, and the shaping bead 5 is snapped into the bayonet 61.

[0049] Furthermore, a triangular plate 62 corresponding to the bayonet 61 is provided above the middle reinforcement strip 6 .

[0050] like Figure 6 、 8 As shown, the triangular plate 62 provided on the top significantly improves the end strength and deformation resistance of the middle reinforcing strip 6 .

[0051] In some embodiments, the shaping strip 5 is an arc-shaped strip, and a reinforcing rib 51 is provided on the upper surface to enhance the structural stability of the shaping strip 5 .

[0052] Furthermore, a clamping plate 52 cooperating with the middle reinforcing strip 6 is provided in the middle position of the upper surface; when installed, it is clamped on both sides of the middle reinforcing strip 6 to achieve rapid positioning and enhance the stability of the installation state.

[0053] In some embodiments, a positioning strip 7 is provided on the arc-shaped blade surface 1 ; correspondingly, a notch 53 corresponding to the positioning strip 7 is provided on the inner side of the shaping strip 5 .

[0054] like Figures 6-10By cooperating with the positioning strip 7 and the notch 53, the arc-shaped blade surface 1 is in close contact with the shaping strip 5, further ensuring the shaping effect.

[0055] It is understandable that the notches 53 on the shaping strips 5 of different specifications all match the positioning strips 7 .

[0056] The utility model provides an arc-shaped plastering trowel with adjustable curvature. When scraping structures with different curvatures, it is only necessary to adjust the curvature of the plastering trowel to correspond thereto without replacing the entire blade body, thereby improving the wide application of the arc-shaped plastering trowel.

[0057] The utility model has many advantages such as simple structure, easy use, and portability; a plastering trowel can be adapted to use with a variety of structures with different curvatures, has good use effect, a wide range of applications, and has great promotion value.
