Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

Example 1

The embodiment of the present invention provides a combined tool 100 , as shown in FIG. 1 , FIG. 2 and FIG. 3 , including: a batch rod 30 , a batch head 40 , a housing 10 and a driving part 20 . Wherein, the batch rod 30 is integrally connected to the batch head 40, and the integral connection may mean that the two are integrally formed, or that the two are connected together through a connecting piece. The housing 10 includes an accommodating space 11 , a through hole 13 and a driving hole 12 . The accommodating space 11 is located inside the housing 10 and can accommodate the batch rod 30 and the batch head 40 . The through hole 13 and the driving hole 12 communicate with the accommodating space 11 and the housing 10 . Externally, the accommodating space 11 can accommodate the batch rod 30 and the batch head 40 , and the through hole 13 is disposed on the casing 10 along the extending direction of the batch rod 30 and the batch head 40 . The driving part 20 is connected to the batch rod 30 through the driving hole 12. The driving part 20 is at least partially located outside the casing 10. The driving part 20 drives the batch rod 30 to move along the extending direction of the batch rod 30 under the action of external force, so that the batch head 40 can pass through. The through hole 13 is exposed to the outside of the casing 10 (as shown in FIG. 2 ) or stored in the receiving space 11 (as shown in FIG. 1 and FIG. 3 ).

In the combined tool 100 proposed by the embodiment of the present invention, the batch rod 30 and the batch head 40 are integrally connected, and the housing 10 has an accommodation space 11 capable of accommodating the batch head 40 and the batch rod 30 . The batch rod 30 can drive the batch head 40 to pass through the through hole 13 to be exposed to the outside of the casing 10 or to be stored in the receiving space 11 . Compared with the prior art, the batch head 40 needs to be taken out and assembled, which is easy to lose. The batch rod 30 and the batch head 40 of the present invention are integrally formed. When the batch head 40 needs to be used, it is only necessary to drive the batch head 40 through the driving part 20. As long as it is exposed outside the casing 10, the bit 40 of the present application does not need to be separated from the batch rod 30 during use, and the bit 40 is not easily lost.

Specifically, the batch rod 30 can be fixedly connected to the bit 40 , or can be detachably connected to the bit 40 . In order to prevent the bit 40 from being lost, the detachable connection in the present application may be different from the connection method of the bit 40 and the batch rod 30 in the prior art, so that the bit 40 and the batch rod 30 cannot be easily separated. In the present application, in the case where the batch rod 30 is detachably connected to the batch head 40, after the batch head 40 is worn and cannot be used normally, only the batch head 40 can be replaced without replacing the batch head 40 and the batch rod 30 together. Of course, when the batch rod 30 is non-detachably connected to the bit head 40, if the bit head 40 is worn and cannot be used normally, the batch rod 30 with the bit head 40 needs to be replaced together.

In order to improve the application range of the combined tool 100, the number of the bit heads 40 is at least two, such as two, three, four and more. Of course, in some embodiments, the number of batch heads 40 may be only one. The types of the bit 40 may include one or more types, including but not limited to common tools such as screwdriver bits, sockets, and external hexagon wrenches. The models and specifications of the bits 40 are different, for example, the models and specifications of the screwdriver bits are different.

Specifically, the batch lever 30 has opposite ends, one end is integrally connected to the bit head 40 , and the other end is connected to the driving part 20 .

In the embodiment of the present invention, the number of the through holes 13 on the housing 10 can be equal to the number of the batch heads 40, that is, each batch head 40 corresponds to one through hole 13, and the axis of the through hole 13 is connected to the batch rod 30 and the batch head 40. The axes are collinear, so that each bit 40 can be exposed to the outside of the housing 10 through its corresponding through hole 13 . Of course, the radial dimension of the through hole 13 should be suitable for passing through the corresponding bit 40 .

It should be noted that, in the embodiment of the present utility model, the collinear axis is not required to have no deviation at all. In practice, there may be a small range of deviation between the axis of the through hole 13 and the axis of the batch rod 30 and the batch head 40. As long as the bit 40 can pass through the through hole 13 when moving along its axis. That is to say, if the radial dimension allowance of the through hole 13 is large, the deviation between the axis of the through hole 13 and the axis of the batch rod 30 and the bit head 40 is also allowed to be large; and vice versa.

The combined tool 100 of the embodiment of the present invention further includes an elastic member 50 and a control assembly 60 . The elastic member 50 is sleeved on the batch rod 30, and the batch rod 30 is provided with a limiting member 31. The elastic member 50 includes a first end and a second end arranged oppositely, and the first end is close to the through hole 13 and abuts the housing 10 or The batch rod 30 is fixedly connected, and the second end is away from the through hole 13 and abuts against the limiting member 31 . The limiting member 31 limits the elastic member 50 to a position on the bit rod 30 away from the driving part 20 and close to the bit head 40 . The control assembly 60 is arranged on the batch rod 30 and is located between the elastic member 50 and the driving part 20 . The control assembly 60 confines the batch head 40 to a position extending or retracting into the through hole 13 , and the elastic member 50 is subject to After pressing, an elastic force is applied to the control assembly 60 to switch the position of the bit 40 . The cooperation of the control assembly 60 and the elastic member 50 in the present invention drives the bit head 40 to switch between the position exposed outside the casing 10 and the position stored in the accommodation space 11 , and the specific principle can be similar to that of a telescopic ballpoint pen. . When the number of bits 40 is one, the principle of the control assembly 60 and the elastic member 50 can be similar to that of a common telescopic ballpoint pen; when the number of the bit 40 is more than one, the principle of the control assembly 60 and the elastic member 50 can be similar to The same as ordinary retractable ballpoint pens or multi-core retractable ballpoint pens. Since the retractable ballpoint pen is in the prior art, the working principle of the control assembly 60 and the elastic member 50 will not be repeated in this application.

The elastic member 50 can be a coil spring and is sleeved outside the batch rod 30 .

The casing 10 may be cylindrical as a whole, and the axes of the bit rod 30 and the bit head 40 are parallel to the axis of the casing 10 , that is, the through hole 13 is located on the top or bottom surface of the cylinder. The driving hole 12 can be arranged with the cylindrical side wall and away from the through hole 13. The driving hole 12 is strip-shaped on the side wall and extends in the same direction as the axis of the housing 10, so that under the action of the external force of the driving part 20, The driving part 20 can slide along the strip, thereby driving the corresponding bit rod 30 and the bit head 40 to move.

Of course, the cross section of the housing 10 may also be oval, polygonal, or the like.

Of course, as a variant, the driving hole 12 can also be arranged on the top surface or the bottom surface of the cylindrical shape, opposite to the through hole 13 .

When the number of the bit heads 40 is more than three, in the cross section of the housing 10 , the bit heads 40 may be evenly arranged in a circular shape.

In order to facilitate holding and prevent slipping, the outer surface of the housing 10 is provided with a grip portion, and the surface of the grip portion is roughened.
