Abstract
Description
Technical Field
[0001] The utility model relates to a multifunctional pliers, which is special in that the pliers have the function of screwing nuts in addition to other functions of the pliers. Background Art
[0002] Pliers are a commonly used work tool with many types and wide applications. They are an indispensable hand tool for clamping and shearing workpieces in assembly, repair and installation work in various industries. Pliers have a common basic structure, which is composed of three parts: a pliers head, a tip and a handle. The basic principle of pliers is to use two levers, which are cross-connected with a pin at a point in the middle so that the two levers can move relative to each other. As long as one end of the pliers (handle end) is operated by hand, the other end can be used to clamp the object. In order to reduce the force used by the user during operation, according to the principle of lever in mechanics, the pliers handle is usually made longer than the pliers head, so that a stronger clamping force can be obtained with less force.
[0003] Pliers can be divided into: clamping and twisting type; shearing type; clamping, twisting and shearing type according to their performance. Their main functions are to clamp objects and cut electrical wires or steel wires. Utility Model Content
[0004] To achieve the above object, the utility model provides the following technical solutions: a multifunctional pliers, comprising a jaw, a pivot portion and a handle, one side of the jaw is designed to The other side of the jaw is designed to be 𠃌 shaped. The 𠃌-shaped jaws include one arm, two arms and four arms. The one arm, two arms and four arms are all fixedly connected. The one arm and two arms use an angle of 60 degrees, and the two arms and four arms use an angle of 80 to 140 degrees. The 𠃌-shaped jaws include three arms and five arms. The three arms and five arms are fixedly connected, and the connection angle is 80 to 140 degrees. In this way, with the cooperation of the jaws on both sides, the three sides of the nut can be clamped when clamping the nut, with three sides spaced apart. Of course, one of the sides is point contact, which plays a tightening role. The inner side of one arm, the side in contact with the nut is 12mm to 48mm long, and the inner side of the two arms, the side in contact with the nut is 13mm to 54mm long. This type of pliers can screw nuts from 8mm to 24mm.
[0005] A multifunctional pliers, comprising a jaw, a pivoting portion, and a handle, wherein one side of the jaw is designed to The other side of the jaw is designed to be 𠃌 shaped. The 𠃌-shaped jaws include one arm, two arms and four arms. The one arm, two arms and four arms are all fixedly connected. The one arm and the two arms adopt a 60-degree angle, and a short connecting arm is used between the one arm and the two arms. The short connecting arm is 4mm long. The two arms and the four arms adopt an angle of 106 to 118 degrees. The four arms are 50mm long, from the top to the pivot center. The 𠃌-shaped jaws include three arms and five arms. The three arms and the five arms are fixedly connected, and the outer side of the connection angle adopts 106 to 118 degrees. In this way, with the cooperation of the jaws on both sides, the three sides of the nut can be clamped when clamping the nut, with three sides spaced apart. Of course, one of the sides is in point contact to play a tightening role. The inner side of one arm, which is in contact with the nut, is 20mm long, and the inner side of the second arm, which is in contact with the nut, is 23mm long. This type of pliers can screw nuts from 8mm to 24mm. In addition, the nut is clamped by three arms, and the first arm, second arm and third arm are at a 10-degree angle to the plane of the pliers, viewed from the side.
[0006] A multifunctional pliers, comprising a jaw, a pivoting portion, and a handle, wherein one side of the jaw is designed to The other side of the jaw is designed to be 𠃌 shaped. The triangular pliers include one arm, two arms and four arms. The one arm and the two arms are connected by sliding. The one arm can slide up and down. No matter how it slides, the one arm and the two arms are always at an angle of 60 degrees. There is a triangular connecting arm between the one arm and the two arms. The triangular connecting arm adopts a triangle but has a rectangular slide inside for the one arm to slide in it. A screw is also set on the triangular connecting arm to fix the one arm. The two arms and the four arms are fixedly connected. The two arms and the four arms adopt an angle of 106 degrees to 118 degrees. The four arms are 50mm long, from the top to the pivot center. The jaws include three arms and five arms. The three arms and five arms are fixedly connected, and the outer connection angle is 106 to 118 degrees. In this way, with the cooperation of the jaws on both sides, the three sides of the nut can be clamped when clamping the nut, with three sides spaced apart. Of course, one of the sides is point contact, which plays a tightening role. One arm is 58mm long, and the inner side of the second arm, the side in contact with the nut is 33mm long. This type of pliers can screw nuts from 8mm to 32mm. In addition, the nut is clamped by three arms, and the one arm, the second arm and the third arm are at an angle of 10 degrees to the plane of the pliers, viewed from the side.

[0013] The technical problem to be solved by the utility model is to make the pliers have the function of screwing nuts while retaining the functions of clamping, cutting and stripping wires. The pliers designed by me include jaws, a pivoting part and a handle, which is characterized in that one side of the jaws is designed to The other side of the jaw is designed to be 𠃌 shaped. The 𠃌-shaped jaws include one arm 1, two arms 2 and four arms 4, which are all fixedly connected, with an included angle of 60 degrees between the one arm 1 and the two arms 2, and a short connecting arm 6 being used between the one arm 1 and the two arms 2, the short connecting arm 6 being 4 mm long, the two arms 2 and the four arms 4 being 106 to 118 degrees in angle, and the four arms 4 being 50 mm long (from the top to the pivot center), and the 𠃌-shaped jaws include three arms 3 and five arms 5, which are fixedly connected, and the connection angle (outer side) is 106 to 118 degrees. Figure 2 , so that with the cooperation of the jaws on both sides, when clamping the nut, the three sides of the nut can be clamped (three sides apart). Of course, one of the sides is in point contact (for compression). In addition to the traditional functions of pliers such as clamping, cutting, and stripping, such pliers also have the function of screwing nuts. The inner side of one arm 1 (the side in contact with the nut) is 20mm long, and the inner side of the second arm 2 (the side in contact with the nut) is 23mm long.
