- the base branch 6 and the bending branch 7 initially extend with their longitudinal limbs 60, 70, between which the cutout 8 ends, which ends in the throat bottom 81 toward the head region 10.
- the handle portion 76 has on its upper side an elongated recess 760, in which the base handle 66 fits.
- the remaining features are opposite to the first variant of the Torque wrench 1 basically unchanged; this also includes the Mess ⁇ markings 69.79.
- the head 90 and the shaft 96 are in alignment with the axis V.
- the cylindrical head 90 with the profiling consisting of the grooves 93 'and webs 94' is of the enclosure 2 enclosed.
- the handle 76 remains unconfirmed, so is neither pulled clockwise nor moved backwards - the entire pawl 4 is not deflected, the pawl spring 47 thus tension-free and the two spring clearances 52,52 'extend unchanged.
- the latching segment 40 is at a small distance from the first and second stop 50, 51 and projects into the nearest groove 93 '. Between the axis V and the front nose 44, the minimum distance a 0 exists.
- FIGS. 4A to 4C This pair of figures corresponds in principle to FIGS. 4A to 4C and shows the torque wrench 1 of the second variant with inserted insertion tool 9 moved in the forward direction, ie a force F acts on the grip part 76 in the clockwise direction, as a result of which the bending branch 7 is close to the maximum deflection is deformed.
- the first branch 72 is for the most part moved out of the free space 67 and the second branch 73 serving as a stop
- the depression 760 is completely open, since the base grip 66 is no longer located therein.
- FIGS. 5A to 5C This group of figures corresponds in principle to FIGS. 5A to 5C and shows the torque wrench 1 of the second variant with inserted insertion tool 9 moved in the reverse direction, ie a force F 'acting counter to the clockwise direction acts on the grip part 76.
- the base branch 6 and the bending branch 7 are close to each other, the latter and the cutout 8 are undeformed.
- the first branch 72 and the second branch 73 are maximally retracted into the free space 67.
- the release torque that has not been overcome causes the insertion instrument 9 to remain stationary, as a result of which the web 94 closest to the pawl segment 40 causes the pawl 4 to deflect.
- the latching segment 40 is pressed in the direction of the second stop 51 and the maximum distance ai between the latching segment 40 and the axis V is set so that the latching segment 40 is disengaged except for the contact of the circular surface of the bars 94 ' with the head 90 of the screwing 9 comes.
- the pawl spring 47 By bending the pawl spring 47, the first spring clearance 52 is now widened, while the second spring clearance 52 'has narrowed.
- the torque wrench 1 is in a third variant. Only the entire pawl 4 with the pawl segment 40 and the course of the pawl spring 47 and the clearance 5 with the adjacent upper first stop 50 and the lower, trough-shaped second stop 51 are modified.
- the pawl segment 40 now has a rather angular tongue shape ending at the front with the protruding into the receiving opening 3 front nose 44, from which the first edge 41 extends upwards, to which a second flank 42 adjoins, which meets the spring outlet 46. Down the front nose 44 follows a third edge 43, which merges into the spring outlet 46.
- the clearance 5 now winds helically from the mouth into the receiving opening 3 within the neck region 11 towards the bottom 53.
- the pawl spring 47 also passes through the clearance 5 helically, dividing the clearance 5 in turn into a first and a second spring clearance 52, 52 "and ends at the spring opening 48.
- the first stop 50 is steeper, and the latch segment 40 is in the momentary rest position relative to the axis V in the minimum distance a-
- the trough contour of the lower stop 51 is more pronounced Elements on the torque wrench 1 are unchanged compared to the predecessor variants, including the measurement marks 69,79.
- This group of figures illustrates the torque wrench 1 third Vari ⁇ ante with inserted Einwindinstrument 9 second variant when operated in the reverse direction, ie on the handle portion 76 sets the rearward force F f .
- the front nose 44 of the pawl segment 40 is moved out of the previously occupied groove 93 'to the circular Ober ⁇ surface of the webs 94' and thereby deflected the entire pawl 4, wherein the pawl segment 40 to the second stop 51st goes there.
- the front nose 44 comes to the axis V in the maximum distance ai, and the second Federke ⁇ space 52 "narrows in particular in the region of the second stop 51, while the first spring clearance 52 extends, in particular in the region of the first stop 50.
