The handling of the screwdriver tip block will now be described.

Figures 3 and 4 illustrate, in solid lines, the tip blocks 12A and 12B in the storage position, wherein they are stored according to a first orientation along the axis Y-Y and are locked to their respective bottoms 40 and 41.

Figure 4 illustrates, in broken lines, the tip blocks 12A and 12B in the gripping position, which is adapted to allow a user to easily grip each of the tip blocks 12A and 12B. This clamping position is different from the storage position of the tip block in which the relative orientation of the tip blocks 12A and 12B relative to the retaining members 24 and 25 and the tip blocks 12A and 12B are relative to the axis YY An orientation has an angular difference.

In the storage position, by the complementarity of the shapes, the retaining members 24 and 25 cooperate with the tip blocks 12A and 12B, respectively (Fig. 5). In the same position, the blade tips 12A and 12B are respectively received and held in the outer casings 22 and 23 of the bodies 20 and 21, and the free ends of the driving portions 14A and 14B of the blade tips 12A and 12B abut against the outer casings 22 and 23, respectively. The baffles 26 and 27 are omitted, and the other end of the tip block abuts the respective coupling members 44, 45.

When the user wishes to move the tip block 12A from its storage position into its gripping position, the user places his or her finger against the aperture 50 of the body 20 of the storage element 18, with the storage element 18 facing the selection The blade tip block 12A is intended to be removed from the storage case 10. The user inserts his or her finger into the aperture and directly acts on the operating head 16A of the tip block 12A according to the arrow F1 of FIG. 4 by the fingertip of the finger. In a limiting sense, the user's finger operates from the second side 40B of the bottom 40 toward the first side 40A of the bottom 40.

By applying a force directly to the operating head 16A, the user generates a rotational torque centered generally at the position of the tailgate 26 against which the drive portion 14A abuts.

Under the action of this rotational torque, the driving portion 14A laterally moves the flexible lug 25A due to the cam type action between the driving portion 14A of the tip block 12A and the inner projection 25B. Flexed.

In the clamping position of the tip block 12A, the holding member 25 still cooperates with the driving portion 14A of the tip block 12A, and the inner protrusion 25B is attributed to the driving portion 14A having a hexagonal cross section with the tip block 12A. The friction of the two opposite faces is elastically engaged.

When the user wishes to move the tip block 12B disposed in the body 21 of the storage element 19 from the storage position into its gripping position, the user places his or her finger against the selected tip block 12B. The force is applied to the operation button 52 of the lever 51 and according to the arrow F2 of FIG.

Under the action of the thrust of the operating button 52, the flexible branch 53 of the lever 51 flexes internally within the meaning defined by the second face 41B toward the first face 41A. The pushing member 55 directly acts on the driving portion 14B of the tip block 12B to generate a rotational torque centered at a position defined by the projecting nose 27A of the tailgate 27, and the nose 27A has the freedom of the driving portion 14B with the tip block 12B. The end of the groove has a complementary shape.

Under the action of the rotational torque, the tip block 12B is pivoted from its storage position into its clamped position, the projecting nose 27A having the tip end block 12B in consideration of the weak lever arm between the push member 55 and the tailgate 27. The pop-up function, the rotational torque is applied from the operating button 52 by the weak lever arm.

In the middle of the configuration in which the cartridge 10 is unfolded in a wallet manner (i.e., the configuration between the closed position and the open flat position), the user performs the same manual operation as the manual operation previously performed to move the tip block 12A and 12B move from the storage position to their gripping position. Depending on the position of the tip block to be clamped in the storage case, the user acts by placing his or her finger through the aperture 50 or on the operating button 52 of the lever 51. Each action is made from the second faces 40B and 41B of the bodies 20 and 21 toward the first faces 40A and 41A of the same body.

With the present invention, improved clamping of the tip block, the simplified configuration of the storage case allows for lower production costs.
