Description

Torque screwdriver tool

The present invention relates to a torque driver tool.

Press, the general torque tool is usually used to set the torque value, so that it can select the appropriate torque setting value according to the assembly and disassembly process of various components. The body of the torque tool has a drive head for assembling the screwdriver head. The center of the body of the torsion tool is provided with a central push rod to adjust the torque setting value, and a movable grip is arranged at the end, the grip is against the center push rod, and the center push rod is rotated when the grip is rotated. The grip will be abutted against the top for axial movement, and then the torque setting value of the torque tool can be adjusted, and then the user can perform the locking operation. In addition, for the convenience of storage, the gripper is provided with a storage portion for storage. The part can accommodate a plurality of screwdriver heads, so the user does not need to carry the additional head storage box, and the screwdriver head can be replaced by the removal of the screwdriver head from the storage portion of the handle, and the screwdriver handle disclosed by TW408663 is Belonging to this category.

However, in such a conventional torque tool, since the user performs a locking operation to hold the grip to easily apply force, and the torque tool adjusts the torque setting by rotating the grip, the conventional torque tool performs When the lock operation is performed, the grip is easily turned to change the torque setting value, and the user needs to repeatedly adjust the torque setting value of the conventional torque tool to ensure that the torque setting value is fixed, which will reduce the efficiency of the locking operation, and also lock When the solid part is rotated, if the grip is easily caused to slip off the hand when the hand is applied, there is a drawback that needs to be improved.

Therefore, it is necessary to provide a novel and progressive torque driver tool to solve the above problems.

The main object of the present invention is to provide a torque screwdriver tool. When the torque setting value is to be adjusted, the grip of the torque tool can be quickly switched to the rotatable state for adjustment.

At 32 o'clock, the accommodating members 53 and the cover body 51 are arranged side by side in the axial direction 13 (as shown in FIG. 11), which can save space in the accommodating groove 32 and prevent the grip portion 3 from being excessively large; When the cover body 51 pivots away from the accommodating groove 32, the cover body 51 drives the accommodating members 53 to pivot outwardly and the accommodating members 53 pivot away from the cover body 51 to form a fan shape ( As shown in Fig. 12, the screwdriver heads 9 are prevented from being overcrowded, making it difficult for the user to take a driver's head 9. Preferably, the cover 51 and the at least one receiving member 53 are provided with two lugs 56 extending in the present embodiment. The two lugs 56 are respectively provided with a pivot hole. 55, the angles at which the accommodating members 53 are pivoted away from each other are larger, so that the screwdriver head 9 can be taken more conveniently.

It is to be noted that, in this embodiment, the accommodating groove 32 has two side walls 321 , and the two side walls 321 respectively protrude with a limiting guide edge 322 , and the accommodating portion 52 is away from the one of the cover bodies 51 . The two convex portions 54 of the 53 are respectively blocked from the two limiting guide edges 322 toward one side of the body 1 , and the two limiting guide edges 322 are pivoted when the cover 51 is pivoted away from the receiving slot 32 . The two convex portions 54 (shown in FIG. 12 ) of the accommodating member 53 of the cover body 51 can be blocked to prevent the swinging amplitude of the accommodating member 53 from being excessively large or even detached from the accommodating groove 32. The indentation heads 9 are prevented from being inadvertently dropped. The one end of the two limiting guide edges 322 away from the pivoting portion of the cover body 51 is respectively recessed with a notch 323 through which the convex portion 54 can pass. When the accommodating member 53 is received, the two convex portions 54 of the accommodating member 53 which are farthest from the cover body 51 can be detached from the limiting guide 322 via the two notches 323.

In summary, in the torque driver of the present invention, when the grip portion is in the first position and the adjusting member is in the third position, the engaging member is engaged with the flange, and the grip portion cannot be Moving toward the second position, the grip portion is unable to rotate relative to the body, and the locking operation can be performed. When the adjusting member moves to the third position, the engaging member can swing freely without being stuck to the a flange, the grip portion is movable toward the second position to adjust the torque setting.

And when the cover body pivots away from the accommodating groove, the cover body pivots the accommodating members outwardly and the accommodating members are pivoted away from the cover body to form a fan shape, so that the cover body can be The screwdriver head is not too crowded to make it difficult for the user to take a screwdriver.
