Description

drive tool

The present invention relates to hand tools, and more particularly to a driving tool.

Generally, driving tools such as wrenches are used to facilitate the rotation of fasteners (such as screws and nuts), and it is understandable that the torque is proportional to the force arm or force. Therefore, to obtain greater torque is nothing more than increasing the length of the wrench. Or increase the force by hitting with a hammer.

However, an excessive increase in the length of the wrench will also lead to an increase in the demand for the rotation range, and it is very easy to collide with other objects in the surrounding environment, resulting in the unsmooth rotation operation and the inability to be used in a narrow space. However, by increasing the force by hitting with a hammer, the wrench is prone to sliding with the fastener due to improper hitting angle, resulting in friction loss or falling.

Therefore, it is necessary to provide a novel and progressive driving tool to solve the above problems.

The main purpose of the present invention is to provide a driving tool, which can be used in a narrow space through a force-applying rod, and can have a wide range of pivoting through the pivoting of the pivoting member and the detachable reversing toggle member. Angle and various angle configurations are used for rotating operation.

In order to achieve the above-mentioned object, the present invention provides a driving tool, which includes a force-applying rod, a pivoting member and a wrench member. The force-applying rod includes two connecting parts, and the two connecting parts are spaced apart to define a pivoting space; the pivoting piece includes a first end and a second end, and the first end extends into the pivoting space to pivotally connected to the two connecting parts; and the toggle member is detachably positioned at the second end.

The following examples are only used to illustrate possible implementations of the present invention, but are not intended to limit the scope of protection of the present invention, and are described together first.

It can synchronously swing and adjust to the appropriate force application position with the change of the pull angle; or, by pivoting to an appropriate angle, it can avoid surrounding obstacles and extend into a narrow space (such as a car body).

Preferably, the length of the force-applying rod 1 is at least three times longer than the length of the pivoting member 2, so that it can be used in a narrower space.

The toggle member 3 is detachably positioned at the second end 22 (that is, the toggle member 3 must be detached from the pivoting member 2 before the direction can be changed), and the toggle member 3 can have various types like an arm. The position is used in aspects, such as: changing the length of the lever arm as required, and presenting a different angle with the pivot member 2 to avoid obstacles. Among them, the example of changing the length of the lever arm is but not limited to: the wrench member 3 is originally perpendicular to the extension direction of the pivot member 2, and when it is rotated, the lever arm is only the length of the wrench member 3, which is suitable for narrow spaces. used in. According to different needs, the user can also disassemble it and then reassemble it on the second end 22 parallel to the extending direction of the pivoting member 2, so that the force-applying arm increases (the length of the toggle member 3 is the same as the length of the pivoting member 2). The sum of ), which can output a larger torque under the same force.

Preferably, the pivoting member 2 is in the shape of a plate, and the wrench member 3 is in the shape of a plate, so as to be easy to shuttle in the gap. In this embodiment, the thickness of the toggle member 3 is equal to the thickness of the pivot member 2, and the thickness of the pivot member 2 is smaller than the thickness of the two connecting portions 11 to ensure that the two connecting portions 11 have sufficient structural strength to withstand The force from the force application rod 1 is transmitted.

Further, the toggle member 3 includes two clamping jaws 31 and a first joint portion 32 , the two clamping jaws 31 define a clamping opening 311 for accommodating a fastener 61 , the two clamping jaws 31 is used to clamp against the fastener 61. The above-mentioned structural design allows the toggle element 3 to extend into a group 6 to be disassembled in a narrow space through lateral insertion to connect the fastener 61 at the second end. 22 is provided with a second joint portion 23 which is mutually inserted with the first joint portion 32; wherein, one of the first joint portion 32 and the second joint portion 23 is a non-circular convex column, and the other is a The non-circular concave hole is convenient for quick assembly and disassembly by plugging, and can effectively avoid the occurrence of slippage and relative rotation.

More specifically, the toggle member 3 and the force-applying rod 1 are located at opposite ends of the pivot member 2, and can act like a multi-link when rotating, so as to have more flexibility and a better moving angle, such as As shown in FIG. 4 , the toggle member 3 can be rotated in a wide angle range with the fastener 61 as the axis; or, as shown in FIG. (in the shape of a ㄑ), the fastener 61 is driven to rotate so as to easily avoid obstacles (indicated by a dotted circle).

In this embodiment, the pulling member 3 further includes a working part 33 , a base part 34 and a set of connecting parts 35 , the working part 33 is provided with the two clamping jaws 31 and the clamping opening 311 , the connecting part 35 The first joint portion 32 is provided, and two ends of the base portion 34 are respectively connected to the working portion 33 and the assembling portion 35; wherein, the working portion 33 and the assembling portion 35 are respectively enlarged portions, in order to have a stronger Structural strength. In addition, the first joint portion 32 is a square hole, the second joint portion 23 is a square column, and the second joint portion 23 is fastened to the second end 22 in order to have a stronger connection structure.

Preferably, the concave hole is a through hole, which is convenient for manufacturing and has the advantage that both the front and back sides can be plugged.

A first distance 51 is defined as a straight line distance from the center point of the first joint portion 32 to the center point of the jaw 311 , and the center point of the pivoting member 2 and the force application rod 1 is pivotally connected to the first joint portion 32 The length of the center point is defined as a second distance 52, and the ratio of the second distance 52 to the first distance 51 is preferably between 0.7 and 1 to ensure that the pivoting member 2 has an appropriate size ratio to meet the actual usage.

Of course, the toggle member 3 is not limited to the above-mentioned form, and the user can replace it with different forms as required. For example, but not limitation, as shown in another embodiment of FIG. 6 , the difference from this embodiment is that the pulling member 3A is a sleeve, and can be rotated through a socket.

Please further refer to the present embodiment of FIG. 1 and FIG. 5 , the first end 21 is provided with a first pivot hole 211 , the two connecting portions 11 are respectively provided with a second pivot hole 111 , and a pivot shaft 4 passes through The first pivot hole 211 and the two second pivot holes 111 are positioned on the two connecting portions 11 , and the pivoting member 2 swings relative to the pivot shaft 4 . In addition, the two connecting portions 11 are respectively plate-shaped, and the two connecting portions 11 are in a U-shape as a whole, and when the pivoting member 2 swings to a position perpendicular to the force-applying rod 1, the pivoting member 2 will laterally abut against the force-applying rod 1. The total pivot angle of the lever 1, that is, the pivoting member 2 is limited to ±90 degrees. The reason is that when the lever 1 is perpendicular to the pivoting member 2, it can generate the maximum torque (the vertical force arm of the force), so through The abutment of the two can improve the stability of the force application and let the user know to achieve the best force application position. In addition, the two connecting portions 11 are laterally abutted against the wrench member 3 to provide a certain frictional resistance under the premise of free swinging, so as to avoid any unexpected swinging of the pivoting member 2 .
