Problems solved by technology

Since the torque generated by turning the two side lugs by hand is small after all, the locking force of the wing nut is not strong, so the wing nut is affected by vibration and other factors to loosen, thus affecting the normal operation of the appliance

Embodiment Construction

[0014] figure 1 Among them, a wing nut wrench includes a handle plate 1 and a seat plate 2, and the handle plate 1 is connected to the seat plate 2. The center of seat plate 2 is provided with the round hole 3 that matches with the round platform of wing nut, and the both sides of round hole 3 are respectively provided with the long slot hole one 4 and the slot two 5 that match with wing nut both sides ears. The length of the handle plate 1 is longer than that of the seat plate 2 . Both the handle plate 1 and the seat plate 2 can be made of stainless steel. In order to reduce the production cost, the handle plate 1 and the seat plate 2 are an integral structure. The length of the handle plate 1 may be 3 to 8 times the length of the seat plate 2 . The thickness of the handle board 1 and the seat board 2 may be 2-3 mm. An angle may be formed between the handle board 1 and the seat board 2 . The angle formed between the handle plate 1 and the seat plate 2 is 120°˜175°. When...

Abstract

The invention relates to a wrench for a butterfly nut. The wrench comprises a handle plate and a base plate, wherein the handle plate is connected with the base plate, a round hole matched with a boss of the butterfly nut is formed in the center of the base plate, the two sides of the round hole are provided with slotted holes matched with two side lugs of the butterfly nut respectively, and the length of the handle plate is larger than that of the base plate. Through the wrench for the butterfly nut, large torque can be applied to the butterfly nut, and therefore locking force of the butterfly nut can be enhanced.

Description

technical field [0001] The invention relates to a wrench for wing nuts. Background technique [0002] An existing wing nut comprises a round platform and two side ears, the two side ears are located on both sides of the round platform, and a screw hole is arranged in the center of the round platform. When using the above-mentioned wing nut, usually the two side lugs are turned by hand to tighten it on the bolt. Because the torque generated by turning the two side ears by hand is small after all, the locking force of the wing nut is not strong, so the wing nut is loosened due to the influence of vibration and other factors, thereby affecting the normal operation of the appliance. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a wing nut wrench, which can apply a larger torque to the wing nut, thereby enhancing the locking force of the wing nut. [0004] In order to solve the above-mentioned technical problems, ...
