Detailed Description
The spring washer single-sided quick installation tool provided by the utility model is explained in the following by combining the accompanying drawings.
Referring to the accompanying drawings 2-4, the utility model provides a single-side quick installation tool for a spring washer, which comprises three parts: the handle comprises a first handle 1, a second handle 2 and a rotating shaft 3, wherein the first handle 1 and the second handle 2 are connected together through the rotating shaft 3.
Illustratively, the shaft 3 is located in the middle of the first handle 1 and the second handle 2, and the spring washer single-sided quick-mounting tool is in the shape of scissors or pliers.
Optionally, as shown in fig. 3, the first handle 1 adopts a 45# steel structure to ensure the rigidity of the part, the end structure (the first sleeve 4) of the first handle 1 is matched with the 10 nail heads of the quick-release nails, so that the spring washer is not damaged during installation, and the nail heads of the quick-release nails can be effectively propped against the washer.
Illustratively, the dimension between the first sleeve 4 and the rotating shaft 3 of the first handle 1 is 112mm, which ensures that the tool does not interfere with the product flap when the spring washer is installed.
The second handle 2 adopts a 45# steel structure to ensure the rigidity of the part; the end structure (the second sleeve 5) of the second handle 2 is matched with the outer surface of the spring washer, so that the spring washer can be quickly installed at a theoretical position; the second sleeve 5 of the second handle 2 is provided with a hiding hole of the locking pin 20 of the quick release nail 10, so that the second handle 2 is prevented from interfering with the locking pin 20; the dimension between the second sleeve 5 of the second handle 2 and the rotating shaft 3 is 112mm, so that the tool cannot interfere with the product opening cover when the spring washer is installed.
Illustratively, the axes of the first sleeve 4 and the second sleeve 5 are in a straight line when the tail portions of the first handle 1 and the second handle 2 are kneaded.
The axes of the first sleeve and the second sleeve are perpendicular to the axis of the rotating shaft 3.
