The utility model discloses a technical scheme: the utility model provides a multiplicable turning torque's screwdriver, includes the handle, handle one side be equipped with the connecting seat, the connecting seat is equipped with rotatable cutter arbor through the pivot, the junction of connecting seat and cutter arbor is equipped with the first spacing groove and the second spacing groove of parallel and perpendicular to handle axis respectively, the cutter arbor outside is equipped with the sleeve, the one end that the handle was kept away from to the cutter arbor is equipped with the detachable tool bit through the sleeve.

In the screwdriver capable of increasing the rotating torque, the handle is provided with the accommodating cavities for storing the screwdriver bits, the number of the accommodating cavities is greater than or equal to two, and the accommodating cavities are parallel to each other.

In the screwdriver capable of increasing the rotating torque, one end of the screwdriver rod is provided with a through hole for penetrating through the rotating shaft, the other end of the screwdriver rod is provided with a pyramid groove for connecting the screwdriver head, and the screwdriver head is provided with a pyramid corresponding to the pyramid groove.

In the screwdriver capable of increasing the rotating torque, the first limiting groove and the second limiting groove are cylindrical clamping grooves, and the diameters of the clamping grooves are consistent with the diameter of the screwdriver rod.

In the screwdriver capable of increasing the rotating torque, the rotating shaft is a fixing bolt, and a gasket and a fastening nut corresponding to the fixing bolt are arranged on the rotating shaft.

Compared with the prior art, it can realize the regulation of screwdriver moment of torsion through set up the pivot on the connecting seat at the handle to set up first spacing groove and second spacing groove in the connecting seat and realize the fixed of cutter arbor, make the cutter arbor be difficult to take place to slide, improve the safety in utilization, and the tool bit can be replaced, and the suitability is better, this practical structure retrencies, and stable performance is difficult for the trouble.

Drawings

Fig. 1 is a schematic structural diagram of the present invention;

fig. 2 is a schematic view of a part of the structure of the present invention.

The labels in the figures are: 1-handle, 2-connecting seat, 3-cutter bar, 4-first limiting groove, 5-cutter head, 6-sleeve, 7-second limiting groove, 8-containing cavity and 9-rotating shaft.

Detailed Description

The following description is made with reference to the accompanying drawings and examples, but not to be construed as limiting the invention.

Example 1. A screwdriver capable of increasing turning torque is shown in figures 1-2 and comprises a handle 1, wherein a connecting seat 2 is arranged on one side of the handle 1, a rotatable cutter bar 3 is arranged on the connecting seat 2 through a rotating shaft 9, a first limiting groove 4 and a second limiting groove 7 which are parallel to and perpendicular to the axis of the handle 1 are respectively arranged at the connecting position of the connecting seat 2 and the cutter bar 3, a sleeve 6 is arranged on the outer side of the cutter bar 3, and a detachable cutter head 5 is arranged at one end, far away from the handle 1, of the cutter bar 3 through the sleeve 6.

The handle 1 is provided with accommodating cavities 8 for storing the cutter head 5, the number of the accommodating cavities 8 is more than or equal to two, and the accommodating cavities 8 are parallel to each other.

One end of the cutter bar 3 is provided with a through hole for penetrating through the rotating shaft 9, the other end of the cutter bar 3 is provided with a pyramid groove for connecting the cutter head 5, and the cutter head is provided with a pyramid corresponding to the pyramid groove.

The first limiting groove 4 and the second limiting groove 7 are cylindrical clamping grooves, and the diameters of the clamping grooves are consistent with the diameter of the cutter bar 3.

The rotating shaft 9 is a fixing bolt, and a gasket and a fastening nut corresponding to the fixing bolt are arranged on the rotating shaft 9.

The utility model discloses when using, from the tool bit 5 that holds in the chamber 8 selection and the screw that will twist in the handle 1 and correspond, the quantity more than or equal to two that hold chamber 8, and hold between the chamber 8 parallel to each other, conveniently look for required tool bit 5 like this, then unscrew pivot 9, then adjust cutter arbor 3. If when the screw is not tightened, the cutter bar can be moved into the first limiting groove 4, then the rotating shaft 9 is tightened, so that the cutter bar 3 cannot rotate, one end of the cutter bar 3 is provided with a through hole used for penetrating through the rotating shaft 9, the other end of the cutter bar 3 is provided with a pyramid groove used for connecting the cutter head 5, the outer side of the cutter bar 3 is provided with a sleeve 6, the cutter head 5 is provided with a pyramid corresponding to the pyramid groove, the selected cutter head 5 is installed in the sleeve 6, the cutter head 5 and the cutter bar 3 can be matched, and therefore the screw can be tightened. When meetting the screw because inside rust or when fastening hard up lead to being difficult to dismantle, transfer cutter arbor 3 to second spacing groove 7, tighten pivot 9 and fastening nut again, make cutter arbor 3 difficult to rotate, prevent to make cutter arbor 3 take place to rotate because of the resistance is too big to produce the fish tail to screw or equipment. The cutter bar 3 is adjusted into the second limiting groove 7, the force arm of the screwdriver can be increased, and under the same force effect, the torque can be increased, so that the screwing and unscrewing operation of the screw is more convenient. After using the utility model discloses afterwards, can pull down tool bit 5, arrange tool bit 5 in handle 1 hold the chamber 8, can reduce the potential safety hazard.
