Abstract

PURPOSE:To provide a wrench which can impart thrusting force when a socket and the like are rotated, can be quickly rotated even in a narrow working space when torque required is small, and also can impart reliable force at the time of fastening and loosening. CONSTITUTION:The wrench is made up of a handle B with a fixed mouth 1, and of a turning movement mouth A fastened to the handle with a shaft C, the turning movement of the turning movement mouth with the handle rocked allows a socket and like to be quickly fastened/loosened, the wrench can be handled in the same manner as an ordinary wrench and the like are handled with the socket and the like held by the turning movement mouth and the fixed mouth, and in the case of threaded engagement, the socket and the like can be pushed in the direction of thrusting while being rotated.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a work of attaching and detaching a bolt and a nut, or a socket and a pipe when joining them together.
It relates to tools that can be used efficiently.

[0002]

2. Description of the Related Art Conventionally, there are various tools for attaching and detaching bolts and nuts such as pliers and spanners, but especially when attaching and detaching sockets and joints incorporated in piping, force is required. When he did not, he often relied on direct manual work because he could be more efficient.

[0003]

As a result, it has been difficult to work with conventional tools only in narrow places, especially in places far from the hand and where the hand cannot be fully utilized. This tool is used for turning the socket etc. such that when the required torque is small, the speed is high, and when it is large, a certain force is obtained, and in addition, in the screwing direction while turning the socket etc. By adding the power of, it is intended to complement the role of the hand and to perform work efficiently even in situations that have conventionally been difficult.

[0004]

[Means for Solving the Problem] A tool that can efficiently turn a socket or the like incorporated in a pipe even from the lateral direction is that it is easy to change the position at which the socket and the like engage, and The angle that can be turned is large. According to the present invention, a turning port and a fixed port satisfying such conditions are provided, and these two ports can be selectively used depending on the magnitude of the torque required for turning a socket or the like, and two ways of turning can be performed. . This is a handle (B) with a fixed mouth (1),
It is composed of a turning port (A) stopped by a shaft (C), and the turning port is integrated with a fixed port of the handle, so that it becomes a part of a normal port.

1. A normal mouth is provided separately from the turning mouth by dividing the function of the mouth.

2.

[0005]

[Operation] The rotation of the rotation opening depends on the swing of the handle.
At this time, bite in the direction of turning the socket etc.
In order to give the next rotation, when changing its position, return it with the rotation port floating from the socket. This one
A cycle can be swiftly repeated by repeating the rotation of the socket and the like at hundreds of degrees. Turning the socket or the like by turning the turning port is limited only when the required torque for that is small, but in general, the required torque is small in most parts where the socket or the like to be attached / detached is turned. The space required for turning the socket etc. may be much narrower than the case of turning with a conventional spanner etc. Further, at the side of the fixed opening, the screwing force can be applied while keeping the engagement between the socket or the like and the rotating opening, so that the screw can be easily screwed in a place that is out of reach. When tightening or loosening, when the torque required to rotate the socket etc. is large and the pivot opening does not rotate due to the swing of the handle,

According to the first aspect of the present invention, when it is further pressed, the turning port is in a state of sandwiching the socket and the like with the fixed port of the handle. At this time,
The rotation port loses the function of rotation, and the socket and the like firmly bite the socket with the fixed port of the handle. Can be turned into. In addition, it is possible to do it with a regular mouth that has a separate turning action.

【Example】

 Example 1 1

1. A perspective view showing a structure for a right-hand screw in which a turning opening and a mouth of a handle are formed into a substantially semi-circular shape, and a notch is provided therein. Figure 2 shows the operation when the socket (D) is turned by turning the turning port. Here, when the solid-line handle is moved almost in parallel so as to be in the state of the chain line, it turns. With the mouth engaged with the socket, the rotating mouth rotates the socket by 120 degrees while rotating around the shaft as a fulcrum. Then, in the state of the chain line, if the handle is slightly lifted and the handle and the turning port are returned to the state of the solid line, the repetition can be performed, and the movement of the handle and the turning port seen here is rocking. It is turning. Figure 3 shows the socket
This is when turning with the same action as an ordinary spanner. At this time,
The turning port cannot turn because the socket is sandwiched between the handle and the fixed port, and when a force that pushes the socket against the handle is applied, the whole can work as a spanner. Then, in the action from the solid line to the state of the chain line, the socket rotates 60 degrees while obtaining sufficient force. FIG. 4 shows the portion of the handle that contacts the socket when the socket is screwed in. The shaded portion (2) is that portion. Here, the screw can be screwed easily because it can be turned like a wrench while the turning port is engaged with the nut while applying a screwing force to the socket.

Example 2 5 FIG.

According to a first aspect of the present invention, the turning port has a trapezoidal shape in order to accommodate a plurality of socket sizes. The operation is the same as in the case of FIG. 1, and is a perspective view showing a configuration for a right-hand screw. FIG. 6 shows the positional relationship of biting between the turning opening and the socket when turning a large socket by the same action as the spanner in the case of FIG. FIG. 7 shows the positional relationship of biting between the rotation opening and the socket when the small socket is rotated by the same action as the spanner in the case of FIG.

Example 3 8 FIG.

1. A guide (E) is provided on a side surface of a turning opening to limit the movement of the turning opening.
It is intended to enable swiveling quickly and at the same time to apply a screwing force.
It is for the same right-hand thread as the case of the figure.

Example 4 9 FIG.

2. A perspective view of a rotary mouth which is independent and has a normal mouth (3) at the opposite position of the handle, wherein the rotary mouth is screwed in, quickly turned, and changed. Tighten with a regular mouth.

[0010]

EFFECTS OF THE INVENTION With a wrench having a turning port, there are two ways to turn a socket or the like. When the torque required to rotate the socket etc. is small, one operation of the pivot opening by swinging the handle can rotate hundreds of degrees, and it is possible to rotate the socket etc. efficiently because the bite position can be easily changed. . Further, since a lateral force for screwing can be applied to the side surface of the socket or the like, the screw can be easily screwed. In addition, for reliable tightening and loosening, the mouth can be changed and the force of the handle can be applied directly like a general spanner without depending on the rotation of the rotating mouth, and work in narrow places or out of reach. It also makes it easier.
