Description

Angle gauge and hand tool with the same

technical field

The present invention relates to a hand tool, in particular to an angle gauge which can be installed on the hand tool for angle measurement and a hand tool with the angle gauge.

Background technique

In some cases, when using hand tools to lock the workpiece, such as locking the nut of the tire with a wrench, in addition to setting the torque value of the wrench, further, the wrench will be required to lock the nut to After setting the torque value, turn it at a predetermined angle in the direction of force application at least once to ensure the torque value applied by the locking workpiece. In order to know the angle value, please refer to Figure 1, which is a conventional angle. The gauge 10 includes: a sleeve 11 and an angle plate 12, the sleeve 11 is sleeved on a tool 13, the other side of the sleeve 11 can be sleeved on a workpiece, when the tool 13 rotates, The tool 13 will drive the sleeve 11 and the angle plate 12 to rotate, and the rotation angle of the tool can be judged by the angle mark of the angle plate 12 rotated.

However, the sleeve 11 and the angle plate 12 of the conventional angle gauge 10 are integrally arranged, and different angle gauges 10 need to be prepared for different sizes of the sleeve, resulting in inconvenience in storage and preparation. In addition, the sleeve 11 is generally square. The hole 111 is connected with the tool 13, so the angle of the angle plate 12 can only be rotated based on 90 degrees, and it is not easy to adjust the angle. Furthermore, the angle gauge is arranged below the tool 13, except that it will block the position of the workpiece, when the tool 13 is operated, if it is operated in a relatively narrow space, the angle plate 12 located below will touch the surrounding environment and cause damage. Make the tool 13 inoperable.

The connecting member 40 has a socket portion 41 , a socket portion 42 and a circumferential portion 43 ; the socket portion 41 is disposed on the top, and is formed into a cylindrical hole relative to the pivot portion 32 . The socket portion 41 A ring groove 411 is arranged on the inner wall of the cylindrical hole. The pivoting portion 32 is pivoted in the sleeve portion 41 and can be freely rotated. The block 323 of the elastic positioning member 33 is elastically clamped to the ring. in the groove 441; the embedding portion 42 is arranged at the bottom of the socket portion 41, in this preferred embodiment, it is formed as a square cylinder, and its configuration can be carried out according to different needs The shape is not limited by this shape; the circumferential portion 43 is disposed on the outer circumferential side of the socket portion 41 ; the socket portion 41 , the embedded portion 42 and the circumferential portion 43 of the connecting member 40 are along a The second axis L2 is coaxially arranged.

The positioning member 50 has a connecting portion 51 , a positioning portion 52 and an indicating portion 53 . In the center of the connecting portion 51 is a set of connecting holes 511 pivoted on the outer side of the circumferential portion 43 so that the connecting holes 511 The axis of the second axis is coaxial with the second axis L2, so that the positioning member 50 can rotate relative to the connecting member 40 with the second axis L2 as the axis. The positioning portion 52 is protruded from the assembly portion 51. On one side, a through hole 521 is formed on its side, and a pressing member 522 is screwed into the through hole 521 on the outer side of the positioning portion 52. An L-shaped positioning rod 523 is passed through the through hole 521. The positioning rod 523 can be screwed by the pressing member 522 to be fixed in the through hole 521; the top surface of the distal end of the positioning portion 52 is protruded with an indicator portion 53, and the indicator portion 53 is provided with an arrow 531 to indicate the direction toward the angle portion The angle of 31 is marked 311.

The top of the head 61 is used. The surface is concave with a fitting portion 611, which is formed as a complementary square hole relative to the fitting portion 42 of the connecting member 40; Inside the fitting portion 611; the fitting portion 611 of the head portion 61 is arranged along a third axis L3, after assembly, the first axis L1, the second axis L2 and the third axis L2 are coaxial set up.

After the hand tool 60 has been applied to a predetermined torque value, the hand tool 60 is rotated by a predetermined angle according to the specifications. At this time, the angle gauge 20 is assembled to the hand tool 60, please refer to FIG. As shown in Fig. 7, first loosen the pressing member 522, so that the positioning rod 523 can rotate and move freely, so that the positioning rod 523 can be fixed on a reference position B, and then screw the pressing member 522 to fix the positioning rod 523 is held against the fixed place; then, please refer to FIG. 7 , and then turn the angle portion 31 on the display member 30 , because the pivot portion 32 is pivoted on the socket portion 41 of the connection member 40 , Therefore, the display member 30 can be rotated relatively, and the reference point of the angle indicator 311 of the angle portion 31 is rotated to the position of the arrow 531 of the indicator portion 53, such as 0 degrees or 90 degrees. When the position of the angle portion 31 is properly rotated Then, referring to FIG. 8 , the shaft 62 of the hand tool 60 is forced to rotate, so that the head 61 of the hand tool 60 will rotate, and when it rotates, the embedment part 42 of the connecting member 40 is locked. is arranged in the fitting portion 611, so the connecting member 40 will rotate synchronously, and the socket portion 41 on the top of the connecting member 40 will also drive the pivoting portion 32 to rotate together, so that the angle portion 31 will also rotate. However, because the positioning part 52 of the positioning member 50 is stuck on the reference position B, the positioning member 50 cannot be rotated. The outer side of the circumferential portion 43 of the hand tool 60 rotates, thereby causing a relative angular displacement between the angle portion 31 and the indicating portion 51, so we can know that the head 61 of the hand tool 60 rotates relative to the fixed indicating portion 51. how much angle.

If multiple rotation angles are required, please refer to FIG. 9 , because the display member 30 can be rotated relative to the connecting member 40 , so as long as the display member 30 is rotated, the pivot portion 32 is positioned relative to the socket portion 41 . By rotating, the relative position between the angle portion 31 and the indicator portion 53 can be adjusted, so that the indicator portion 53 can be re-indicated at the reference point position, and then the angle measurement is repeated.

In addition, it is worth mentioning that, please refer to FIG. 10 , when ordinary people apply force to operate the hand tool 60 , they are accustomed to holding the shaft 62 with one hand and the head 61 with the other hand; the display member 30 can also be used as a The hand tool 60 is used for holding by the user's hand, because the pivoting portion 32 is pivoted in the socket portion 41 of the connecting member 40 , so when the hand is held on the display member 30 , the hand tool 60 rotation is not disturbed.
