Further, described rectangular metal block top view cross section is square or rectangular, rectangular metal block recess four sidewalls or two sidewalls penetrating from top to bottom.
Further, gear has two main functions, and one rotates for driving annular ring, and it two is conduct force downwards, improves and digs efficiency.
Further, described power transmission shaft adopts electric drill transmission, and power transmission shaft lower end is identical with normal drill bit.
Further, in order in operation, allow rectangular metal block keep geo-stationary (not rotate with the annular ring being enclosed within outside simultaneously, about 2 to 4 through holes are made a call at the position should not affecting pinion rotation at rectangular metal block, intending digging the hole that on object, 2 to 4, corresponding site brill is same before construction, insert by metallic rod, fixing rectangle metal derby).
Further, described cutter adopts carbide alloy or diamond to make.
Further, described outer peripheral gear offers many annular incision be parallel to each other.
The utility model coaxial fixed installation one on drive link has the gear of certain thickness (being slightly less than rectangular block height overall), the rectangular metal block that the size also comprising hole that a basis will dig or groove is made, the via hole bottom rectangular metal block to be stretched out with the cogged drive link other end (lower end), metal derby surrounding parcel one circle chain form annular ring, this annular ring top is rotated by gear drive, chain form annular ring is provided with to hard material, the cutter that the mode rotating advance drive by chain is cut material, rotated by power transmission shaft driven gear, gear engages with chain form annular ring to drive chain form annular ring to rotate thus cutter is rotated and cuts object.When gear rotates, hole in power transmission shaft lower end simultaneously, keeps and cut annular ring and synchronously move downward.
If need to penetrate, be directly cut to the end, if do not penetrated, square or rectangle deep trouth can be outputed on material, then with other instruments by the rejecting of material middle part, a square or rectangle deep trouth or hole can be formed, and neat in edge.
Further, described power transmission shaft adopts electric drill transmission, and structure is improved convenient, and tool making is simple.

Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearly, below technical scheme in the utility model be clearly and completely described, obviously, described embodiment is the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As Figure 1-3, it is the same with normal drill bit that cutting of the present utility model device that is square or slot/groove comprises its lower end of power transmission shaft 1, rectangular metal block 3, the chain form annular ring 4 being sleeved on rectangular metal block 3 outside and the gear 2 be arranged on power transmission shaft 1, rectangular metal block 3 empties the middle recess 6 forming installation gear 2 downwards with certain diameter in the middle of top, the via hole 7 passed through for power transmission shaft 1 is also offered bottom rectangular metal block 3, rectangular metal block 3 recess sidewall is penetrating shape (two walls or wall), the gear teeth of gear 2 engage with the chain form annular ring 4 being sleeved on rectangular metal block 3 outside at the penetrating place of metal derby recess 6, drive chain strip annular ring 4 rotates around rectangular metal block 3, described chain form annular ring 4 is provided with and digs cutter 5.
The utility model power transmission shaft 1 adopts electric drill transmission, is equivalent to completely newly found bit part on the basis of traditional electric drill.Principle is that top that drive link is equivalent to drill bit is connected with drill bit jig and also can redesigns connected mode, as hexagon or octagonal bush(ing) chain connection, drive link middle and lower part coaxially fixedly mounts one and has certain thickness gear, one end of drive link is connected (identical with electric drill) with electric drill rig, the drive link other end will to grow below gear one section, and has the function of drill bit.
Make a rectangle or square metal block in addition, there is a via hole centre, the cogged drive link other end is with to insert this hole, metal derby surrounding parcel one circle chain form annular ring, this annular ring top is rotated by gear drive, and bottom has cutter to cut material the mode that hard material rotates by chain drive of advancing.Gear, while drive annular ring rotates, gives power downwards by electric drill handle hand.Drive link and gear, annular are cut to enclose and are moved downward simultaneously.
Further, looking down rectangular metal block 3 cross section can be square, also can be rectangle, with the geometric center of this square or rectangular for initial point, digs recess for diameter with the crown of travelling gear to the distance of crown.When rectangular metal block 3 is square, its four length of sides are identical to tooth root place diameter with the tooth root of gear, so, recess digs rear four sidewalls will become permeability status, and after installation, the gear teeth are exposed at square four sides soon, when rectangular metal block 3 is rectangle, its minor face is identical with the tooth root place diameter of gear, and recess digs latter two sidewall (longwell) will become permeability status, and after installing, the gear teeth expose in both sides.Cutter adopts carbide alloy or diamond to make, and can dig hole or the groove of neat in edge.
Described gear 2 periphery offers many annular incision be parallel to each other, and just as gear is stacked by the gear of several onesize shapes, the tooth of upper lower whorl aligns with tooth, but between cog has certain distance (or gap) up and down.Because annular link chain has certain altitude, can reticulate, the gear teeth engage better with chain.
Last it is noted that above embodiment is only in order to illustrate the technical solution of the utility model, be not intended to limit; Although be described in detail the utility model with reference to previous embodiment, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of each embodiment technical scheme of the utility model.
