Each of the clamping assemblies includes an abutting part having an adjustable distance from a central axis of the positioning through hole. ## Claims ### Claim 1 A positioning device for drilling, comprising: a positioning base provided with a positioning through hole, a plurality of clamping assemblies provided on the positioning base and circumferentially spaced around a central axis, as center, of the positioning through hole, wherein each of the clamping assemblies comprises an abutting part, a distance between the abutting part and the central axis of the positioning through hole is adjustable, wherein each of the clamping assemblies comprises a telescopic bar which has one end provided at the positioning base, and another end on which the abutting part is provided, and at least one interconnecting mechanism comprising an interconnecting gear which is rotatably provided at the positioning base through a hole of the positioning base, the telescopic bars are provided with racks extending along respective extending-retracting directions, the rack and the interconnecting gear is engaged. ### Claim 2 (depends on 1) The positioning device for drilling according to claim 1, further comprising a plurality of interconnecting mechanisms, each comprising one interconnecting gear, wherein all of the interconnecting gears are arranged on a same axis. ### Claim 3 (depends on 1) The positioning device for drilling according to claim 1, further comprising N interconnecting gears, each engaged with the racks of the telescopic bars of two of the clamping assemblies, and wherein the extending-retracting directions of the telescopic bars of the two clamping assemblies driving connected with same one of the interconnecting gears are in the same direction, wherein an included angle between extending-retracting directions of telescoping bars of any two adjacent ones of the clamping assemblies is 180°/N, where N is a positive integer. ### Claim 4 (depends on 3) The positioning device for drilling according to claim 3, wherein the positioning device further comprises a locking mechanism for locking a plurality of the telescopic bars. ### Claim 5 (depends on 1) The positioning device for drilling according to claim 1, wherein the interconnecting gear is installed on the positioning base by a gear shaft which is provided to be coaxial with the positioning through hole, and wherein the positioning through hole runs through the gear shaft. ### Claim 6 (depends on 5) The positioning device for drilling according to claim 5, wherein the interconnecting gear is moveably connected with the gear shaft. ### Claim 7 (depends on 5) The positioning device for drilling according to claim 5, wherein the positioning device further comprises a locking mechanism for locking a plurality of the telescopic bars. ### Claim 8 (depends on 1) The positioning device for drilling according to claim 1, wherein the positioning device further comprises a locking mechanism for locking a plurality of the telescopic bars. ### Claim 9 (depends on 8) The positioning device for drilling according to claim 8, wherein the locking mechanism comprises: a locking nut, threadedly connected with the gear shaft, and a stop collar, co-axially securely connected to the gear shaft, wherein the interconnecting gear is positioned between the locking nut and the stop collar. ### Claim 10 (depends on 9) The positioning device for drilling according to claim 9, wherein the locking nut comprises: a nut body, fitted around the gear shaft, and a pushing bar, provided on the nut body. ### Claim 11 (depends on 1) The positioning device for drilling according to claim 1, wherein the positioning device further comprises a locking mechanism for locking a plurality of the telescopic bars. ### Claim 12 (depends on 1) The positioning device for drilling according to claim 1, wherein in the extending direction of the central axis, the abutting parts of the clamping assemblies each are disposed at same side of the positioning base. ### Claim 13 (depends on 12) The positioning device for drilling according to claim 12, wherein the abutting parts of the plurality of clamping assemblies are all in same one plane. ### Claim 14 (depends on 13) The positioning device for drilling according to claim 13, wherein the abutting part comprises an abutting bar provided to be parallel with and spaced from the telescoping bar, and is provided, by way of an installing base, at an end of the telescoping bar away from the positioning base, and wherein a portion of the abutting bar between the installing base and the positioning base is adjustable in length. ### Claim 15 (depends on 1) The positioning device for drilling according to claim 1, wherein in the extending direction of the central axis, the abutting parts of the clamping assemblies each are disposed at same side of the positioning base. ### Claim 16 (depends on 1) The positioning device for drilling according to claim 1, wherein in the extending direction of the central axis, the abutting parts of the clamping assemblies each are disposed at same side of the positioning base. ### Claim 17 (depends on 1) The positioning device for drilling according to claim 1, further comprising a plurality of positioning sleeves, having different inner diameters, and outer diameters all equal to the diameter of the positioning through hole.
