It is noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of example embodiments according to the present application. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, and it should be understood that when the terms "comprises" and/or "comprising" are used in this specification, they specify the presence of stated features, steps, operations, devices, components, and/or combinations thereof, unless the context clearly indicates otherwise.

Unless specifically stated otherwise, the relative arrangement of the components and steps, the numerical expressions, and numerical values set forth in these embodiments do not limit the scope of the present invention. Meanwhile, it should be understood that the sizes of the respective portions shown in the drawings are not drawn in an actual proportional relationship for the convenience of description. Techniques, methods, and apparatus known to those of ordinary skill in the relevant art may not be discussed in detail but are intended to be part of the specification where appropriate. In all examples shown and discussed herein, any particular value should be construed as merely illustrative, and not limiting. Thus, other examples of the exemplary embodiments may have different values. It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, further discussion thereof is not required in subsequent figures.

The above structure of the utility model solves the problem that the intercepting length of the existing single-saw blade reciprocating saw is difficult to accurately control during operation.

Fig. 1 is a schematic structural view of a reciprocating saw with two saw blades and jaw faces according to a preferred embodiment of the present invention.

The invention is further described below with reference to fig. 1: in this embodiment, a dual blade maxillofacial reciprocating saw comprises: first saw bit 1, second saw bit 2, the dead lever 4, connecting block 5 and handle 6, handle 6 is connected with the one end of connecting block 5, first saw bit 1 and second saw bit 2 set up on connecting block 5 and are located the offside of the link of connecting block 5 with handle 6, the lower extreme of first saw bit 1 and the lower extreme of second saw bit 2 all are equipped with the sawtooth, the front end of first saw bit 1 and the front end of second saw bit 2 all form the saw bit top 3 of arcuation, and be provided with dead lever 4 between first saw bit 1 and the second saw bit 2. The handle 6 may be provided with anti-slip grooves, as shown in the figure, three anti-slip grooves are provided thereon. According to the embodiment, the whole double-saw-blade maxillofacial reciprocating saw is made of metal.

According to the utility model discloses a preferred embodiment, first saw bit 1 and second saw bit 2 are parallel to each other, and during the intercepting skeleton, can guarantee that same notched both ends shape is unanimous, the later stage coaptation of being convenient for.

According to the utility model discloses a preferred embodiment, dead lever 4 sets up with first saw bit 1 and second saw bit 2 are perpendicular, simple structure, and easily fixed again can keep good stability at the operation in-process, guarantees the operation effect.

According to the utility model discloses a preferred embodiment, dead lever 4 sets up on the upper portion of saw bit top 3, and fixed saw bit front portion that can be better prevents that operation in-process saw bit front portion from producing deformation and influencing the operation effect.

The first blade 1 and the connecting block 5 and the second blade 2 and the connecting block 5 may be rigidly connected or detachably connected, for example, by providing an insertion opening on the connecting block 5, the first blade 1 and the second blade 2 are detachably inserted into the insertion opening of the connecting block 5. When the reciprocating saw is in rigid connection, the double-saw-blade maxillofacial reciprocating saw has better integrity, so that the influence on the operation effect caused by the loosening of the saw blade can be avoided; when the detachable connection is adopted, the saw blade can be detached, and when the saw blade is damaged, the saw blade is convenient to replace.

According to the present invention, a rigid connection or a detachable connection is provided between the fixing rod 4 and the first saw blade 1 and between the fixing rod 4 and the second saw blade 2, for example, the first saw blade 1 and the second saw blade 2 are provided with holes having internal threads, the fixing rod 4 is provided with external threads, and the fixing rod 4 is detachably connected to the first saw blade 1 and the second saw blade 2 through threads. When the reciprocating saw is in rigid connection, the double-saw-blade maxillofacial reciprocating saw has better integrity, and can avoid the influence on the operation effect caused by the loosening of the saw blade; when the first saw blade 1 or the second saw blade 2 is detachably connected, the first saw blade 1 or the second saw blade 2 can be detached independently, and when one of the saw blades is damaged, only one of the saw blades is replaced, so that the cost is reduced.

The connecting block 5 and the handle 6 can be rigidly connected or detachably connected (for example, by a screw thread). When the reciprocating saw is in rigid connection, the double-saw-blade maxillofacial reciprocating saw has better integrity, and can avoid the influence on the operation effect caused by the loosening of the saw blade; when here for can dismantling the connection, convenient to detach changes, has appeared damaging when handle 6 or connecting block 5, need not whole change, only need dismantle after change one of them part can.

In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the orientation words such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" etc. are usually based on the orientation or positional relationship shown in the drawings, and are only for convenience of description and simplification of description, and in the case of not making a contrary explanation, these orientation words do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore, should not be interpreted as limiting the scope of the present invention; the terms "inner and outer" refer to the inner and outer relative to the profile of the respective component itself.

Spatially relative terms, such as "above … …," "above … …," "above … …," "above," and the like, may be used herein for ease of description to describe one device or feature's spatial relationship to another device or feature as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if a device in the figures is turned over, devices described as "above" or "on" other devices or configurations would then be oriented "below" or "under" the other devices or configurations. Thus, the exemplary term "above … …" can include both an orientation of "above … …" and "below … …". The device may be otherwise variously oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

It should be noted that the terms "first", "second", and the like are used to define the components, and are only used for convenience of distinguishing the corresponding components, and if not stated otherwise, the terms have no special meaning, and therefore, the scope of the present invention should not be construed as being limited.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
