Description

Technical Field

[0001] This utility model relates to the field of building construction tools, and more specifically, to a trowel for finishing wall surfaces. Background Technology

[0002] Plastering trowels used in building decoration are used to smooth concrete. For finishing, a double-handled, large-plate stainless steel trowel (referred to as a trowel) should be used. Any depressions found during finishing should be promptly filled with mortar and then smoothed again to ensure the wall surface after thin plastering is flat and meets requirements. Edges and corners should be trimmed straight with the trowel. The trowel has two handles and is relatively long. When using it, the operator holds both handles to move the trowel. However, in most trowels, the two handles are fixed to the blade. This can cause operators of different builds to have excessively long arm reach, making it inconvenient for them to use.

[0029] The spring 12 is supported by the telescopic rod 11 and the movement of the lifting frame 9 is positioned and guided.

[0030] The pressing shaft 13 is sleeved in the handle 14, and the top end of the pressing shaft 13 penetrates and extends above the handle 14.

[0031] When the pressing shaft 13 is pressed, the position is limited by the top end of the handle 14, so that the locking teeth 10 and the rack 4 are separated as long as the pressing shaft 13 is pressed to the bottom, and the user does not need to try to press the unlocking force, and the use is simple.

[0032] The handle 14 has two, and the two handles 14 are located on the front and rear sides of the mounting rail 2.

[0035] The placing rack 15 is installed on the right side of the mounting rail 2, the mounting block 5 can be taken out from the mounting rail 2 after work is completed, and then the mounting block 5 is placed horizontally in the placing rack 15 for storage, since the knife plate 1 cannot be folded, the overall height of the device is reduced, and storage and carrying are facilitated.

[0036] The placing rack 15 is "L" shaped, and each group of placing racks 15 has two sides and is symmetrically arranged front and back.

[0037] Each group of two placing racks 15 together form a placing position, and the mounting block 5 can be positionally fixed.

[0038] The working principle and use process of the utility model are as follows:

[0039] Before use, the mounting block 5 is placed in the placing rack 15, the mounting block 5 is taken out from the placing rack 15 by the handle 14, and the front side handle 14 is taken as an example, the mounting block 5 is placed into the front side of the mounting rail 2, so that the roller one 6 and the roller two 7 are in contact with the side surface and the bottom surface of the inner cavity of the mounting rail 2.

[0040] Then the pressing shaft 13 is pressed down, the pressing shaft 13 drives the lifting frame 9 and the locking tooth 10 to move down, the locking tooth 10 is located below the rack 4 and is staggered with the rack 4, then the handle 14 is moved to a comfortable position of the operator, then the pressing shaft 13 is released, at this time the spring 12 in the compressed state pushes the lifting frame 9 up under the elastic action, the locking tooth 10 is inserted into the rack 4, and the position of the handle 14 is fixed;

[0041] Finally, the other handle 14 is inserted into the installation rail 2 from the other side and fixed in the appropriate position, then the folding operation is carried out;

[0042] After the operation is completed, the pressing shaft 13 is pressed down repeatedly, the installation block 5 is taken out from the installation rail 2, and then placed in the placing frame 15 for storage and carrying.
