The utility model relates to a hand tool 1 with a steering handle, which comprises a first handle 10, a second handle 20, a rotary clamping set 30, a locking set 40 and a spring 50. The rotating latch set 30 is disposed between the first handle 10 and the second handle 20 through the locking set 40. The spring 50 is disposed in the second handle 20 and elastically abuts against the rotary latch set 30. The first handle 10 and the second handle 20 can be rotated relatively and positioned by the rotating latch set 30, so as to change the angle of the first handle 10 relative to the second handle 20.

The first handle 10 includes a first body 11 and a first receiving groove 12, and the first body 11 has a first chamfered surface 13 at one end. The second handle 20 is movably engaged with the first handle 10. The second handle 20 includes a second body 21 and a second receiving slot 22, and the second body 21 has a second inclined plane 23 at one end thereof for correspondingly engaging with the first inclined plane 13. Specifically, the first chamfer surface 13 and the second chamfer surface 23 are respectively disposed in a substantially elliptical shape.

In this embodiment, the first handle 10 is provided with a locking cover 14 on the opposite side of the first chamfer 13. In addition, the second handle 20 is provided with a tool head 24 on the opposite side of the second chamfer 23.

The rotary latch assembly 30 includes a rotary block 31 and a latch block 32. The rotating block 31 is disposed in the first vessel 12. The engaging block 32 is disposed in the second receiving groove 22, and one end of the rotating block 31 can extend into the engaging block 32 and can be selectively engaged with the engaging block 32.

It should be noted that the total length of the first receiving groove 12 and the second receiving groove 22 is greater than the length of the stud 41. Accordingly, under the action of external force, the first handle 10 or the second handle 20 can move relatively along the extending direction of the stud 41.

Specifically, the rotating block 31 is provided with at least two positioning ribs 311 and a locking rib 312 on the outer peripheral surface. In addition, the locking block 32 has at least two locking ribs 321 on the outer surface and at least two locking grooves 322 on the inner wall surface. In addition, at least two positioning grooves 121 are disposed on the inner wall of the first accommodating groove 12 facing the positioning ribs 311, and the rotating block 31 is positioned in the first accommodating groove 12 by the positioning ribs 311 passing through the positioning grooves 121.

In addition, at least two catching grooves 221 are formed on the inner wall of the second receiving groove 22 facing the catching ribs 321. The locking block 32 is positioned in the second receiving groove 22 by the locking ribs 321 passing through the locking grooves 221.

Furthermore, the locking assembly 40 includes a stud 41 and a nut 42. The stud 41 penetrates through the locking block 32 and the rotating block 31. One end of the stud 41 is fixed in the first groove 12, and the other end is locked with the nut 42 and inserted in the second groove 22.

In the present embodiment, the stud 41 includes a bolt head 411 and a threaded section 412. The bolt head 411 is positioned on the catch block 32. The threaded section 412 is fitted with the nut 42.

The locking assembly 40 further includes a first pin 43. In addition, the first body 11 is provided with a first insertion hole 110 at one side thereof, which is communicated with the first accommodating groove 12. The first latch 43 is inserted into the first receptacle 110 and abuts against the rotary block 31. Preferably, the rotation block 31 is provided with a rotation hole 310. The first pin 43 is inserted into the rotation hole 310, thereby fixing the rotation block 31 in the first receiving groove 12.

On the other hand, the locking assembly 40 further includes a second pin 44. The second body 21 is provided with a second insertion hole 210 at one side thereof, which is communicated with the second receiving groove 22. The second pin 44 is inserted into the second insertion hole 210 and abuts against the detent block 32. The locking block 32 is provided with a locking hole 320. The second pin 44 is inserted into the locking hole 320, thereby fixing the locking block 32 in the second receiving groove 22.

It should be noted that the first pin 43 and the second pin 44 can be configured as screws or fixing nails, but the practical implementation is not limited thereto.

Furthermore, the spring 50 is sleeved outside the stud 41 and elastically abuts against the rotating block 31. When the first handle 10 and the second handle 20 move relative to each other, the spring 50 is stretched or compressed along with the movement of the first handle 10. In this embodiment, the rotating block 31 and the locking block 32 can be locked when the spring 50 is compressed and can be disengaged when the spring 50 is stretched.

Please refer to fig. 4 and 5, which are schematic diagrams illustrating the operation of the hand tool with the steerable handle of the present invention when steering. As shown in fig. 4, the first handle 10 or the second handle 20 can move relatively when pulled by an external force, and the first handle 10 can drive the rotating block 31 to disengage from the locking block 32 during the moving process.

Referring to fig. 5, after the rotation block 31 is disengaged from the locking block 32, the first handle 10 and the rotation block 31 rotate to a specific angle relative to the second handle 20 by using the stud 41 as a rotation center, and then apply a force to the second handle 20 to make the second inclined plane 23 of the second handle 20 attach to the first inclined plane 13 of the first handle 10. At this time, the locking rib 312 of the rotating block 31 is inserted into one of the locking grooves 322, so that the rotating block 31 and the locking block 32 are locked with each other.

Fig. 6 and 7 are a combined cross-sectional view and a schematic perspective view of the hand tool with a steerable grip of the present invention after being steered. As shown in the drawings, after the first handle 10 and the second handle 20 of the present invention are rotated to a certain angle (e.g. 90 degrees), the rotating block 31 can be engaged with the engaging block 32 at the certain angle, so as to position the first handle 10 and the second handle 20 at the certain angle. Accordingly, the tool head 24 is rotated along with the second handle 20 for operation.
