Referring to fig. 1 and 2, the present embodiment discloses a reaming auxiliary tool, which includes a guide 100 and a fitting 200, the guide 100 includes a first guide portion 110 and a fixing portion 120, the first guide portion 110 has a length in a first direction, the fixing portion 120 is disposed at a first end of the first guide portion 110, the fitting 200 includes a second guide portion 210, a force application portion 220 and a connection portion 230, the second guide portion 210 has a length in the first direction, the second guide portion 210 is in threaded connection with the first guide portion 110 in the first direction, the force application portion 220 is disposed on the second guide portion 210, the connection portion 230 is disposed at a second end of the second guide portion 210, the connection portion 230 is used for connecting a reamer 010, wherein the second end of the second guide portion 210 is far away from the guide 100 relative to the first end of the second guide portion 210.

Referring to fig. 3, in use, the connecting portion 230 is connected to the reamer 010, the guide 100 is fixed by a fixing portion 120 using a clamping tool such as a pliers or a wrench, and the second guide portion 210 is threadedly connected to the first guide portion 110 in a first direction, and the force applying portion 220 rotates the second guide portion 210 to rotate the fitting member 200 and advance the fitting member in the first direction, so that the reamer 010 is fed in a different direction from the direction in which the reamer 010 advances, and the reamer 010 can be fed in a narrow space, which is advantageous to improve the reaming efficiency and quality.

Example 1

Referring to fig. 1 and 2, in the present embodiment, the first guide portion 110 is a screw, the fixing portion 120 is a first fixing block, and a projection of the first fixing block in the first direction is a polygon. When using, first fixed block can be fixed through centre gripping instrument such as pliers, spanner, consequently, the shape of first fixed block can be quadrangle, hexagon or octagon etc. wherein the comparatively commonly used setting of first fixed block is the metal block of outer hexagonal. Of course, for the convenience of holding, the fixing portion 120 is further connected with a holding portion having a length in a second direction perpendicular to the first direction. Thus, the holding portion can replace clamping tools such as pliers and a wrench, and the holding portion and the fixing portion 120 can be connected more firmly through welding or integrated forming, so that slipping between the fixing portion 120 and the clamping tools is avoided in the using process.

In order to be engaged with the first guide portion 110, the second guide portion 210 is a hollow cylinder, and the inner wall of the cylinder is provided with threads and is connected with the first guide portion 110 through the threads. Before reaming, the first guide part 110 penetrates the second guide part 210, and the first end of the second guide part 210 can abut against the fixing part 120, so that the overall length of the guide 100 and the fitting piece 200 in the first direction is reduced, and when reaming is needed, the fitting piece 200 is screwed in the first direction through the fixing guide 100 and the rotating fitting piece 200, so that the feeding amount is provided for the reamer 010.

Referring to fig. 2, in some examples, the cylinder has a first inner wall 211 and a second inner wall 212, a radius of the first inner wall 211 is smaller than a radius of the second inner wall 212, the screw thread is disposed on the first inner wall 211, and the second inner wall 212 is adjacent to the connection portion 230 relative to the first inner wall 211 in the first direction. Thus, the length of the thread in the first direction can be reduced, the resistance of the fitting piece 200 in the rotating process can be reduced, and the convenience in use can be improved.

In some examples, the force application portion 220 is a first protrusion (not shown) disposed on an outer wall of the second guide portion 210, and a projection of the first protrusion in the first direction is a polygon. For example, the force application part 220 may be an outer hexagonal nut welded to an outer wall of the second guide part 210.

Referring to fig. 1, in other examples, the force application portion 220 is a plurality of cutting surfaces disposed on an outer wall of the second guide portion 210, and the plurality of cutting surfaces are distributed around the second guide portion 210. For example, the second guide portion 210 is a hollow cylinder, and a plurality of cutting surfaces are machined on an outer wall of the cylinder, thereby forming a structure similar to that of an outer hexagonal nut. Of course, when the second guide part 210 is a hollow polygonal prism, a plurality of sidewalls of the polygonal prism may be used as the force application part 220.

Referring to fig. 1 or 2, in some examples, the connecting portion 230 is a blind hole or a stepped hole having a polygonal inner wall, for example, the connecting portion 230 is a blind hole with four inner corners, and the size of the blind hole is adapted to the size of the end of the reamer 010, so that the blind hole can be connected to the reamer 010 and can prevent relative sliding between the blind hole and the reamer 010, thereby providing power to the reamer 010.

Example 2

In this embodiment, the first guiding portion 110 is a hollow cylinder (not shown), the cylinder is provided with an internal thread, the fixing portion 120 is a second protrusion disposed on an outer wall of the cylinder, and a projection of the second protrusion in the first direction is a polygon. In order to cooperate with the first guide part 110, the second guide part 210 is a screw (not shown), the second end of the second guide part 210 is provided with a polygonal block structure, and the middle of the block structure is provided with a polygonal blind hole or a stepped hole, so that the outer wall of the block structure may be used as the force applying part 220 and the blind hole or the stepped hole in the middle of the block structure may be used as the connecting part 230.
