In contrast, when an element is referred to as being "directly on" another element, the <RTIgt; The terms "a" and "at least one" are not intended to mean a particular quantity, but rather to illustrate and cite one of the embodiments.

Referring to FIG. 1 to FIG. 8 , the rotary locking torque wrench 100 of the present invention comprises a main rod body 10 , a grip tube 20 , at least one dice 30 , a steering ring 40 and a torsion adjusting assembly 50 . . The control ring 40 of the present invention can be rotated between a locking position and a relaxed position for locking the main body 10 and the grip tube 20, or adjusting the torque value through the torque adjustment assembly 50. among them:

The main body 10 has a first end 11 and an opposite second end 12, the first end 11 is provided with a driving portion 13, and the driving portion 13 can be a ratchet sleeve joint type for receiving the working piece, and The outer peripheral ring of the second end 12 is provided with a plurality of positioning grooves 14 disposed along the length direction of the main rod body 10, and the outer circumference of the main rod body 10 is further provided with a plurality of torque values. Number 15.

The grip tube 20 is sleeved at one end of the second end 12 of the main rod body 10. The grip tube 20 has a grip portion 21 at one end and a plurality of torque segment values 22 at the other end, and the grip portion 21 is At least one through slot 23 is provided between the torque segment values 22, and at least one through slot 23 extends laterally along the length of the grip tube 20 and corresponds to the positioning slot 14. In the present embodiment, at least one of the slots 23 is generally rectangular in shape and penetrates the periphery of the grip tube 20.

At least one dice 30 is movably disposed in at least one of the slots 23. Each of the latches 30 has a first end 31, a second end 32 opposite the first end 31, and a body 33 connected between the first end 31 and the second end 32, the body 33 and the grip The axes of the tubes 20 are parallel. Wherein, in the present embodiment, each of the dice 30 is cylindrical.

The steering ring 40 is placed over the grip tube 20 and is rotated relative to the grip tube 20 between the locked position and the relaxed position. As shown in FIG. 3, the inner circumference of the control ring 40 is provided with at least one action groove 41 for correspondingly and receiving at least one die 30. In the present embodiment, the control ring 40 is provided with a uniform through hole 42 in the axial direction, and the action groove 41 is recessed from the inner wall of the through hole 42. Each of the action grooves 41 has a first depth zone. 411 and a second depth zone 412, the first depth zone 411 is coupled to the second depth zone 412 and disposed along the inner circumference of the steering ring 40, and the depth of the second depth zone 412 at the inner periphery of the steering ring 40 is greater than the first The depth zone 411 is at the depth of the inner circumference of the steering ring 40. When the steering ring 40 is in the locked position, each first depth zone 411 corresponds to each of the latches 30, and the latch 30 is engaged with the Between the positioning groove 14 and the first depth zone 411 of the action groove 41, and when the steering ring 40 is rotated to the relaxed position, the second depth zone 412 corresponds to each of the rafters 30, and the rafter 30 can be moved to the The positioning groove 14 is between the positioning groove 14 and the second depth zone 412 of the working groove 41.

In addition, the outer circumference of the control ring 40 is polygonal, so that the user can easily drive and operate when the operation is performed, and the outer circumference of the grip tube 30 is also polygonal, and the outer circumference of the grip tube 30 and the control ring 40 are respectively It is roughly composed of a plurality of planes and a plurality of corners. The position of the outer circumference of the steering ring 40 and the end angle of the steering ring 40 are respectively aligned with the plane and the end angle of the outer circumference of the grip tube 30.

The torque adjustment assembly 50 is disposed between the main rod body 10 and the inside of the grip tube 20. When the control ring 40 is in the relaxed position, the user can rotate the grip tube 20 to rotate the grip tube 20 relative to the main rod 10 to adjust the pre-force of the torque adjusting assembly 50 acting on the driving portion 13, thereby adjusting the torque wrench. The torque value, wherein the torque torque value 22 and the torque value display the corresponding position of the number 15, the user can understand the current torque value state of the torque wrench. In particular, since the positioning groove 14 of the main rod body 10 has a plurality of positioning grooves, the torque value of the torsion force value 22 does not correspond to the torque value display number 15 (for example, just between two scales). In this case, the user can micro-turn the grip tube 30 so that the catch 30 is indeed positioned in one of the positioning slots 14 so that the torque segment value 22 is exactly aligned with the torque value display number 15 for accurate positioning.

In addition, in the present embodiment, the aforementioned dice 30, the action slot 41, and the slot 23 are respectively two so as to be corresponding to each other, wherein the two slots 23 are attached to the outer circumference of the grip tube 20. One minute round spacing setting.

Referring to FIG. 5 to FIG. 8 , a schematic diagram of the actual operation of the control ring 40 is illustrated. As shown in FIG. 5, the control ring 40 is in a locked position, wherein the dice 30 respectively correspond to the positioning slot 14 and the first depth zone 411, and are fastened thereto. Between the two, the grip tube 20 cannot rotate relative to the main rod 10 in this locked state.

As shown in FIG. 6 to FIG. 8 , the user can use one hand to cut the steering ring 40 to rotate the steering ring 40 relative to the grip tube 20 to rotate the steering ring 40 from the locking position to the relaxed position, wherein the The dice 30 respectively correspond to the positioning slot 14 and the second depth zone 412, and because the depth of the second depth zone 412 is greater than the first depth zone 411 in the inner circumference of the steering ring 40. Within the depth of the circumference of 40, when the user rotates the grip tube 20 and rotates relative to the main rod 10, the forceps 30 can be at the second depth of the positioning groove 14 and the action groove 41. The movable displacement between the zones 412 is such that the steering ring 40 does not engage the latch 30 without restricting the rotation of the gripper tube 20 relative to the main shaft 10 in order to adjust the torque of the torque wrench.

Thereby, the present invention rotates between the locking position and the relaxed position by operating the control ring 40 to lock the forceps 30 between the control ring 40 and the grip tube 20, or to move on the control ring 40 and the grip. Between the tubes 20, the grip tube 20 can be locked with the main rod body 10 or can be rotated relative to adjust the torque of the torque wrench, so that the user can switch the operation with one hand, and provide a more convenient operation mode. Moreover, the overall machine component of the creation is relatively simple, and has no complicated structural combination, and has the advantages of low manufacturing cost and simple assembly.

Although the present invention has been described in terms of a preferred embodiment, it is obvious to those skilled in the art that various changes can be made without departing from the spirit and scope of the invention. The above embodiments are merely illustrative of the present invention and are not intended to limit the scope of the present invention. Any modification or change that is not in violation of the spirit of this creation is the scope of patent application for this creation.
