Description

Technical Field

[0001] The utility model relates to the field of building construction tools, in particular to a building tool shovel. Background Art

[0002] The structure of the existing construction tool shovel can refer to a construction sand shovel disclosed in Chinese patent publication number CN206350303U. The tool shovel includes a shovel handle, one end of the shovel handle is fixedly connected to a handle, the other end of the shovel handle is provided with a shovel head screwed to the shovel handle, and the surface of the shovel handle is provided with an anti-slip pattern partially surrounding the shovel handle.

[0003] When using a tool shovel, in order to increase the speed of shoveling sand and soil, workers will step on the shovel head every time they shovel to drive it to completely immerse in the sand and soil. This method is more labor-saving, but the shovel head is very close to the sand and soil, and it is inevitable to dirty shoes and pants when stepping on the shovel head, resulting in inconvenience in using the tool shovel; when shoveling sand and soil, generally start from the bottom of the sand pile. When the shovel head is immersed in the sand and soil, the shovel head will be pressed by the surrounding sand and soil and difficult to shovel up. In this case, the existing tool shovel cannot use force and can only rely on hand strength to lift the shovel head, resulting in more laborious shoveling of sand and soil. Utility Model Content

[0004] In view of the two shortcomings of the above-mentioned tool shovel, the purpose of the utility model is to provide a construction tool shovel which is labor-saving and not easy to stain shoes and pants during use.

[0005] In order to solve the above technical problems, the utility model is solved by the following technical solutions:

[0006] A construction tool shovel comprises a shovel handle, the end of the shovel handle is connected to a shovel head, a labor-saving mechanism is arranged near the shovel head on the shovel handle to assist workers in shoveling or scooping up sand and soil, the labor-saving mechanism comprises a connecting shaft arranged transversely on the shovel handle, a treading component protruding from one end of the connecting shaft for people to step on, and a supporting component arranged on the connecting shaft to support the ground when the workers shovel, a mounting hole for the connecting shaft to pass through is opened on the shovel handle, and a fastening structure for fixing the connecting shaft to the shovel handle is arranged at one end of the connecting shaft away from the treading component.

[0007] By adopting the above scheme, workers can step on the tread component to shovel, and the tread component still remains outside the sand pile after the shovel head is immersed in the sand. Therefore, the tread component can not only save effort, but also is not easy to dirty shoes and pants. When shoveling, the supporting component can support the ground as a fulcrum. In this state, the shovel head and the shovel handle form a lever. The worker only needs to hold the shovel handle away from the shovel head and use the shovel handle as a labor-saving lever. With the help of the supporting component, the shovel head and the sand in the shovel head can be lifted up. When the shovel head is lifted up, it can get rid of the pressure from the sand pile and easily produce sand. Therefore, the construction tool shovel in this scheme is more labor-saving when shoveling and shoveling sand, and it is not easy to dirty shoes and pants when shoveling, so it is very convenient to use.

[0008] Preferably, the supporting component includes a base plate, connecting plates arranged parallel to both ends of the base plate, a through hole opened on the connecting plate for the connecting shaft to pass through, and a support block protruding from the bottom of the base plate and abutting against the ground when shoveling. After the connecting shaft passes through the through hole, the connecting plates are located on both sides of the shovel handle.

[0009] Preferably, the support block is made of wear-resistant metal.

[0010] By adopting the above solution, the wear-resistant metal can reduce the wear of the support block during use and extend the service life of the support block.

[0011] Preferably, the pedal component includes a pedal rod integrally provided with the connecting shaft, the diameter of the pedal rod is larger than the connecting shaft, and after the connecting shaft passes through the through hole, the end of the pedal rod abuts against one of the connecting plates.

[0012] Preferably, the fastening structure comprises a threaded section protruding from one end of the connecting shaft away from the pedal rod and a nut arranged on the threaded section, and the diameter of the pedal rod is larger than that of the connecting shaft.

[0013] Preferably, the fastening structure further includes a spring washer arranged between the nut and the connecting plate.

[0014] By adopting the above scheme, when the nut is tightened, the distance between the nut and the pedal rod is reduced, driving the two connecting plates to press the shovel handle to fix it. After the nut presses the spring washer, the spring washer will produce elastic deformation, and at the same time, a reaction force is applied to the nut to drive the thread of the nut to fit closely with the thread on the thread segment to increase the pressure, which can prevent the construction tool shovel from vibrating during use and causing the nut to loosen.

[0015] Preferably, the pedal rod is provided with a clamping structure for clamping a tool for operation, and the clamping structure includes at least a pair of mutually parallel clamping surfaces provided on the pedal rod.

[0016] By adopting the above scheme, when assembling the construction tool shovel, the worker can clamp the nut and the clamping surface with the tool at the same time, and apply force on both sides to tighten or loosen the nut, making the installation and removal of the treading part and the supporting part easier and more convenient.

[0017] Due to the adoption of the above technical scheme, the utility model has remarkable technical effects: workers can step on the treading component to shovel, and the treading component still remains outside the sand pile after the shovel head is immersed in the sand. Therefore, the treading component can not only save labor, but also is not easy to dirty shoes and pants; when shoveling, the supporting component can support the ground as a fulcrum. In this state, the shovel head and the shovel handle form a lever. The worker only needs to hold the shovel handle away from the shovel head and use the shovel handle as a labor-saving lever. The shovel head and the sand in the shovel head can be lifted up with the help of the supporting component. When the shovel head is lifted up, the pressure from the sand pile can be eliminated, and the sand can be easily produced. Therefore, the construction tool shovel in the present scheme is more labor-saving when shoveling and shoveling up sand, and it is not easy to dirty shoes and pants when shoveling, so it is very convenient to use.
