[0004] In actual use, this type of plastering trowel can only be used to plaster flat walls. If the wall surface has convex or concave designs, it is difficult to effectively plaster special-shaped wall surfaces. Utility Model Content
[0005] In view of the deficiencies in the prior art, the utility model provides a plastering trowel, which is used to solve the technical problem that the general plastering trowel in the prior art cannot effectively perform plastering construction on special-shaped wall surfaces.
[0006] The above technical objectives of the utility model are achieved through the following technical solutions:
[0007] A plastering trowel comprises a handle, a connecting block and a plate, wherein the handle is rotatably mounted on the connecting block, the plate is located on a side of the connecting block away from the handle and is detachably connected to the connecting block, a limiting member for limiting the rotation of the handle is provided on the handle, and an adjusting member for causing the plate to deform is provided between the connecting block and the plate.
[0008] Working principle:
[0009] The present application is a plastering trowel, which is mainly used for plastering walls during construction.
[0010] When in use, first change the shape of the plate through the adjustment piece above the plate according to the specific shape of the wall. The changeable shapes include flat shape, convex shape and concave shape, and the actual adjustment is made according to the specific wall shape.
[0011] During actual plastering, for some corners of the top surface of the wall, the angle between the handle and the plate can be adjusted through the limiter, so that the rectangular plate can be rotated relative to the handle so that the longer side can be used to plaster the corner of the top or bottom edge of the wall.
[0012] Beneficial effects obtained:
[0013] First, the knife handle is rotatably installed on the connecting block, which can effectively apply mud to the top or bottom edge of the wall, and when the rectangular plate corresponds to the corner of the top or bottom edge of the wall, the user can grasp the knife handle more comfortably and smoothly.
[0014] Secondly, a limiting member is provided, which can effectively limit the knife handle through the limiting member to prevent the knife handle from rotating during actual plastering.
[0015] Thirdly, an adjusting piece is provided, through which the plate can be effectively deformed, so that the user can more conveniently apply plaster to different special-shaped walls. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0021] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.
[0022] Example:
[0023] Reference Figure 1 to Figure 4The present application is a plastering trowel, comprising a handle 1, a connecting block 2 and a rectangular plate 3. The handle 1 is rotatably mounted on the connecting block 2. A vertical connecting rod 4 is provided on the top of the connecting block 2. The handle 1 is slidably mounted on the connecting rod 4. A fixing pin 5 is provided on the handle 1. The fixing pin 5 slides through the handle 1 and is threadedly connected to the connecting rod 4. A bearing 14 is also provided on the top of the handle 1 and between the fixing pin 5, so that the handle 1 can be rotated relative to the fixing pin 5 more easily. A handle groove 15 is provided on the handle 1 to facilitate the user to grab the handle 1.
[0024] like Figure 1 and Figure 3 As shown, the knife handle 1 is provided with a limit piece for limiting the rotation of the knife handle 1, and the limit piece includes a limit pin 7 and a limit spring 8. The connecting rod 4 is axially provided with a plurality of limit slots 9. The limit pin 7 slides through the side wall of the knife handle 1 and is engaged with one of the limit slots 9. The limit spring 8 is sleeved on the limit pin 7, and one end of the limit spring 8 is fixedly connected to the limit pin 7 and the other end is fixedly connected to the side wall of the knife handle 1. This arrangement can effectively make the limit pin 7 always fixed in one of the limit slots 9 through the coordination of the limit pin 7 and the limit spring 8, so that the knife handle 1 can be limited from rotating relative to the connecting rod 4.
[0025] like Figure 1 , Figure 3 and Figure 4 As shown, the plate 3 is located on the side of the connecting block 2 away from the shank 1 and is detachably connected to the connecting block 2. An adjusting member for deforming the plate 3 is provided between the connecting block 2 and the plate 3. Connecting strips 10 are fixedly provided on both sides of the connecting block 2. Long strip-shaped connecting holes 11 are provided on the two connecting strips 10. The adjusting member includes a plurality of positioning bolts 12 and a plurality of positioning nuts 13 corresponding to the positioning bolts 12. The plurality of positioning bolts 12 are evenly fixedly installed on the plate 3, and the ends are all penetrated into the corresponding connecting holes 11. The plurality of positioning nuts 13 are rotatably installed on the connecting strip 10 and are respectively threadedly connected to the ends of the plurality of positioning bolts 12 passing through the connecting holes 11. The plurality of positioning nuts 13 can be rotatably fixedly installed on the connecting strip 10 via bearings 14. This arrangement can effectively adjust the length of the plurality of positioning bolts 12 extending out of the nuts by rotating the plurality of positioning nuts 13, thereby further adjusting the shape of the plate 3. When all the plurality of positioning bolts 12 extend out of the positioning nuts 13, the plate 3 is in a flat shape, as shown in FIG. Figure 4 As shown, when only the positioning bolts 12 at the ends of the two connecting strips 10 are extended, the plate 3 is in a convex shape, and the user can adjust it in different shapes according to the actual situation.
[0026] Working principle:
[0027] When in use, firstly, according to the specific shape of the wall, by adjusting the length of the plurality of positioning bolts 12 extending out of the nuts, the shape of the plate 3 is further adjusted. The changeable shapes include flat shape, convex shape and concave shape, and the user can adjust according to the actual corresponding wall shape. When plastering, for some corners of the top surface of the wall, the limit pin 7 can be stretched to make the limit pin 7 leave the limit groove 9, and the handle 1 can be further rotated to change the angle between the plate 3 and the rectangular plate 3 so that the plate 3 rotates relative to the handle 1. In the case of convenient gripping by the user, the longer side of the plate 3 corresponds to the corner of the top or bottom side of the wall for plastering.
[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
