[0038] Embodiment one:

[0039] The utility model proposes a wall plastering device, include: U-shaped handle frame 2, U-shaped handle frame 2's top handle bar is the hollow two-end plugging structure;

[0040] The bottom of the two short side rods of the U-shaped handle frame 2 is symmetrically connected with two convex connecting blocks 201, and the bottom of the two convex connecting blocks 201 is fixedly connected with the scraper 1. The top end handle rod of the U-shaped handle frame 2 is slidably connected with the auxiliary hand holding frame 3, and the auxiliary hand holding frame 3 is composed of a top end handle rod and two vertical insertion rods symmetrically welded on the top end handle rod. The two top end handle rods are in sliding fit with the top end handle rod of the U-shaped handle frame 2. The top end middle part of the scraper 1 is symmetrically provided with two positioning sleeves 101, and the bottom end of the vertical insertion rod is in insertion fit with the corresponding positioning sleeve 101.

[0041] In the conventional use state, the U-shaped handle frame 2 is positioned and held in a state perpendicular to the scraper 1, and the construction personnel can drive the scraper 1 to move on the wall surface by holding the U-shaped handle frame 2 which is positioned and held, so as to realize the plastering of the wall surface. The auxiliary hand holding frame 3 can fix and hold the U-shaped handle frame 2 in the vertical use state through the two vertical insertion rods, so as to avoid the U-shaped handle frame 2 lacking of the holding driving of the positioning in the hand in the conventional use state, and the U-shaped handle frame 2 is deflected to release the force, which affects the moving and scraping of the U-shaped handle frame 2, and helps to ensure the normal and stable use of the plastering device in the conventional use state.

[0042] The two vertical insertion rods of the auxiliary hand holding frame 3 are separated from the two positioning sleeves 101, so as to release the U-shaped handle frame 2, and the U-shaped handle frame 2 is deflected and adjusted. The U-shaped handle frame 2 can reduce the support height after being deflected and inclined or horizontal, so as to facilitate the sliding and insertion of the device into the closed narrow space, which enables the device to plaster the wall surface in the closed narrow space, and is suitable for the plastering operation of the wall surface in the closed space. Compared with the prior art, the application is more widely used and has better practicability.

[0043] The auxiliary hand holding frame 3 is slidably installed, and can slide outwardly relative to the U-shaped handle frame 2. When the auxiliary hand holding frame 3 slides outwardly, the auxiliary hand holding frame 3 can be used as a holding part of the scraper 1 and the length of the holding part is extended. Through the extended holding part, the scraper 1 can be pushed and slid into a deeper closed narrow space for use, which enables the device to plaster the wall surface in a deeper closed space, and helps to further improve the practicability.

[0044] One end of the top end handle rod of the U-shaped handle frame 2 is slidably connected with a plug shaft 204 through a spring, and the first end of the plug shaft 204 is in insertion fit with the corresponding vertical insertion rod.

[0047] Preferably,

[0048] Two through positioning holes are symmetrically arranged on the vertical insertion rod near the insertion shaft 204, and the insertion shaft 204 is selectively inserted into the two through positioning holes;

[0049] The insertion shaft 204 is selectively inserted into the two through positioning holes, so that the auxiliary hand-held frame 3 can be positioned at the initial position or the outwardly protruding use state.

[0050] Based on the first embodiment, the second embodiment is as follows:

[0051] A row of positioning blocks 102 is arranged on the scraper 1 at the position of the convex connecting block 201, and the bottom side of the convex connecting block 201 is sleeved with the row of positioning blocks 102.

[0052] The mounting sleeve 202 is welded on one side of the convex connecting block 201 away from the U-shaped handle frame 2, and the short insertion shaft 203 is slidably arranged in the mounting sleeve 202, and the short insertion shaft 203 is inserted into the positioning block 102 at the middle position of the row of positioning blocks 102.

[0053] The scraper 1 is detachably mounted with the two convex connecting blocks 201 and is positioned by the two short insertion shafts 203, which facilitates the separate disassembly and replacement of the scraper 1 when it is worn or damaged, without the need to replace the entire device, thereby reducing the overall maintenance cost of the device.

[0060] The two vertical insertion rods of the auxiliary hand-held frame 3 are separated from the two positioning sleeves 101, so that the U-shaped handle frame 2 is released, and the U-shaped handle frame 2 is deflected and adjusted; after being deflected and inclined or horizontal, the U-shaped handle frame 2 can reduce the support height, so that the device as a whole can be conveniently slid into a narrow and closed space, and the wall surface in the narrow and closed space is plastered;

[0061] The auxiliary hand-held frame 3 is slidably installed, and can slide towards the outer side of the U-shaped handle frame 2; when the auxiliary hand-held frame 3 slides outward, the auxiliary hand-held frame 3 can be used as a holding part of the squeegee 1 which is positioned and held and can extend the length of the holding part; through the extended holding part, the squeegee 1 can be pushed and slid into a deeper narrow and closed space, and the wall surface in the deeper narrow and closed space is plastered;

[0062] The insertion shaft 204 is selectively inserted and matched with the two through positioning holes, so that the auxiliary hand-held frame 3 is inserted and positioned in an initial or outwardly protruding use state.
