Wherein the open type is suitable for factories needing rapid torque adjustment; the protection type is suitable for using fixed torque force for a long time, and can prevent field operators from adjusting the torque force value without permission.
Please refer to fig. 1 to fig. 3, which show a torque display device of a mechanical pneumatic/electric screwdriver according to a first preferred embodiment of the present invention, wherein the torque display device 1 is open; the specific implementation mode comprises: a base wire ring 11 screwed on the circumferential surface of the torque cylinder 21 of the pneumatic screwdriver 2 to perform axial displacement so as to form a tightening or loosening state, and a base wire 111 of any type (such as a groove) is formed on one side of the base wire ring 11; a torsion adjusting ring 12 axially combined and sleeved on the base line ring 11, a cut-off inner concave surface 121 formed on the circumferential surface of the torsion adjusting ring 12, a plurality of inner windows 122 which are staggered with each other and have any geometric shape (such as strip shape and the like) and are hollow-out, torsion value numbers 123 engraved on any edge of the inner windows 122, and a fixing screw 124 inserted in proper position on the circumferential surface of the torsion adjusting ring 12; a cap 15 for axially coupling the torque barrel 21 of the pneumatic/electric driver 2 to provide a coupling tool head; thereby, when the baseline ring 11 is overlapped in the torque adjustment ring 12, the baseline 111 is displayed through one of the inner windows 122 and corresponds to the torque value number 123.
Referring to fig. 4 to fig. 6, a torque display device of a mechanical pneumatic/electric screwdriver according to a second preferred embodiment of the present invention is shown, wherein the torque display device 1 is a protective type; the specific embodiment comprises: a base wire ring 11 screwed on the circumferential surface of the torque cylinder 21 for axial displacement to form a tightening or loosening state, and a base wire 111 of any type (such as a groove) is formed on one side of the base wire ring 11; a torsion adjusting ring 12 axially combined and sleeved on the base line ring 11, wherein a section of inner concave surface 121 is formed on the circumferential surface of the torsion adjusting ring 12, a plurality of inner windows 122 which are staggered with each other and have any geometric shape (such as strip shape and the like) and are hollow are distributed on the inner concave surface 121 in proper positions, and torsion value numbers 123 engraved on any sides of the inner windows 122, so that when the base line ring 11 is superposed in the torsion adjusting ring 12, the base line 111 can be displayed through one of the inner windows 122 and corresponds to the torsion value numbers 123; a torsion sheath 13 axially sleeved on the torsion adjusting ring 12 and capable of freely rotating, wherein an outer window 131 which is also in any geometric shape (such as oblong shape) and is hollowed out is arranged on the circumferential surface of the torsion sheath 13, and the torsion sheath 13 is rotated to enable the outer window 131 to clearly and completely see the torsion value number 123 aligned with the inner window 122 and the base line 111; a fixing ring 14 axially sleeved on the torque sheath 13 and screwed to the head of the pneumatic/electric driver 2, and two oil seals 141 are disposed at two axial sides in the fixing ring 14, wherein one oil seal 141 is used to prevent the fixing ring 14 from loosening, and the other oil seal 141 is used to sleeve the outer diameter of the torque sheath 13, so as to generate a little resistance, and the torque sheath 13 is not too loosened, so that the outer window 131 can be slowly rotated and adjusted to align with the inner window 122, thereby achieving the effect of reading torque value number; a cap 15 axially coupled to the torque barrel 21 of the pneumatic driver 2 to provide a coupling tool head.

For example, in the open type torque display device 1, when calibrating, the fixing screw 124 is loosened by the tool wrench, the torque adjusting ring 12 is rotated to a fixed value, for example, to 6.0Kgf-cm, the actual torque value of the pneumatic/electric driver is tested by a torque tester, and the average value is recorded to obtain an actual torque value, the torque value of the torque adjusting ring 12 is rotated to align to the base line 111 of the base line ring 11 through the inner window 122, and finally the fixing screw 124 is locked and positioned, so that the torque adjusting ring 12 cannot rotate, thereby completing the calibration operation.
When the protective torque display device 1 is calibrated, the fixing ring 14 and the torque sheath 13 are firstly loosened, the torque tester is used for testing the torque value number of the current pneumatic/electric screwdriver and recording the average value, the torque adjusting ring 12 is opened and the base line 111 of the adjusting base line ring 11 is rotated to adjust the torque error value, the inner window 122 is used for reading whether the torque value number is correct after the torque adjusting ring 12 is locked, the torque sheath 13 and the fixing ring 14 are combined after the error is confirmed, the torque sheath 13 is rotated and adjusted before the fixing ring 14 is locked, the outer window 131 is parallel and consistent with the inner window 122, and the fixing ring 14 is locked.
It is to be understood that the described embodiments are merely a few embodiments of the invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
