DETAILED DESCRIPTION

[0025] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0026] like Figure 1-8 A wall plastering device shown in the figure comprises a scraper 1 and a handle 11 arranged on the scraper 1, an adjusting wheel 2 is also arranged between the scraper 1 and the handle 11, the adjusting wheel 2 comprises a fixed clamping ring 21 arranged on the scraper 1 and a movable shaft 22 rotatably arranged in the fixed clamping ring 21 and connected to the handle 11; a locking assembly for locking the relative rotation of the fixed clamping ring 21 and the movable shaft 22 is arranged between the adjusting wheel 2 and the handle 11, through the setting of the adjusting wheel 2, the handle 11 and the scraper 1 can rotate relative to each other, and then when the user uses it, the scraper 1 can be preferably fitted to the surface to be plastered, and then the handle 11 is rotated to a comfortable angle for the wrist, and then the locking assembly is used to lock the fixed clamping ring 21 and the movable shaft 22, so that the scraper 1 and the handle 11 are relatively fixed, so that the worker can perform the plastering operation.

[0027] In one embodiment, a limiting arc groove 23 is provided on the fixed clamping ring 21, and a limiting clamping plate 24 is provided on the movable shaft 22 for sliding in the limiting arc groove 23, so that the movable shaft 22 can be limited in the fixed clamping ring 21 for rotation, wherein the opening size of the limiting arc groove 23 can limit the range in which the limiting clamping plate 24 can rotate to the left and right by ninety degrees, thereby ensuring that the handle 11 can fully adapt to the adjustment limit of the holding posture during application.

[0028] In one embodiment, a connecting shaft 25 is provided on the movable shaft 22. A rear fixed plate 26 is provided at one end of the connecting shaft 25 away from the movable shaft 22. The locking assembly includes a locking ring 3 disposed between the rear fixed plate 26 and the fixed snap ring 21 and movably penetrating through the connecting shaft 25, a pull rod 31 disposed on the locking ring 3 and movably penetrating through the rear fixed plate 26, a first return spring 32 disposed between the locking ring 3 and the rear fixed plate 26, and a rocker 33 rotatably disposed on the grip 11. Opposite sides of the locking ring 3 and the fixed snap ring 21 are both provided with mutually meshing first tooth surfaces 34. The connection position between the rocker 33 and the scraper 1 is located in the middle section of the rocker 33, and an arc-shaped card slot 35 for movably clamping the pull rod 31 is provided on one side close to the pull rod 31. In the normal state, under the action of the locking ring 3 and the first return spring 32, it is pushed to abut against the fixed snap ring 21, so that the first tooth surfaces 34 therebetween mesh with each other. Also, since the rear fixed plate 26 on the movable shaft 22 and the pull rod 31 on the locking ring 3 penetrate through each other relatively, after the first tooth surfaces 34 mesh with each other, the movable shaft 22 and the fixed snap ring 21 are locked, and then maintain a relatively stationary state. When it is necessary to adjust the relative position between the grip 11 and the scraper 1, by pressing one end of the rocker 33 away from the pull rod 31, the other end thereof is reversely lifted to pull the pull rod 31 under the support of the middle hinge point, thereby pulling the locking ring 3 away from the fixed snap ring 21, so that the first tooth surfaces 34 therebetween are disengaged from the meshing state. Then the movable shaft 22 can rotate relative to the fixed snap ring 21, so that the angle between the grip 11 and the scraper 1 is adjusted relatively. Then the rocker 33 is released, so that the locking ring 3 rebounds under the action of the first return spring 32. Then the first tooth surfaces 34 on the locking ring 3 and the fixed snap ring 21 mesh and lock with each other, so that the scraper 1 and the grip 11 are fixed. This way of adjustment enables the user to make real-time adjustments during use and is more likely to find the best holding angle.

[0029] In one embodiment, the handle 11 includes a fixed arm 4 arranged on the rear fixed plate 26, a movable arm 41 rotatably connected to the fixed arm 4, the movable arm 41 has an arc-shaped surface on one side close to the fixed arm 4, and a second tooth surface 5 is arranged on the arc-shaped surface, a limited sliding groove 51 is arranged on the fixed arm 4, a movable plate 52 is arranged for limited sliding in the limited sliding groove 51, one end of the movable plate 52 is movably engaged with the rocker 33, and a folding plate 53 is arranged on the other end, and a block 54 engaged with the limited sliding groove 51 is arranged on the folding plate 53, a push plate 6 is arranged on the movable plate 52, a fixed plate 61 is arranged on the fixed arm 4, and a second return spring 62 is arranged between the push plate 6 and the fixed plate 61. In order to further make the adjustment range of the device wider and better adapt to the gripping state of the user, the handle 11 itself is also set to be fixed. The hinged structure between the fixed arm 4 and the movable arm 41 enables it to be rotated and adjusted in another direction relative to the scraper 1. Specifically, by pressing the seesaw 33, the seesaw 33 abuts against the movable plate 52 and moves backward, and then the block 54 that is engaged with the second tooth surface 5 on the movable arm 41 under normal conditions will disengage from the second tooth surface 5, so that the movable arm 41 can rotate relative to the fixed arm 4. When the rotation adjustment is completed, the seesaw 33 is released, and the movable plate 52 rebounds under the action of the second return spring 62, so that the block 54 on the folding plate 53 is engaged with the second tooth surface 5 again, thereby locking the movable arm 41 so that it can no longer rotate, thereby achieving the purpose of adjustment. By pressing the seesaw 33, the rotation of the movable arm 41 and the movable shaft 22 is controlled at the same time, making the adjustment more convenient.

[0030] In one embodiment, a centering clamp plate 7 is provided on the scraper 1 and is located at the midline position. A groove is provided on the centering clamp plate 7 and is adapted to be engaged with the end of the limiting clamp plate 24 away from the limiting arc groove 23. By setting the centering clamp plate 7, the original position can be easily restored after the handle 11 is rotated to adjust the angle relative to the scraper 1, which is convenient for use in a normal state. The centering clamp plate 7 can be made of a material with good elasticity, such as plastic, so that the limiting clamp plate 24 can be easily engaged into the groove of the centering clamp plate 7.

[0031] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
