[0037] Embodiment I

[0038] As Figure 1As shown in the accompanying drawings and described herein Figures 2-15 As shown in the accompanying drawings and described herein

[0039] As shown in the accompanying drawings and described herein Figures 11-13 As shown in the accompanying drawings and described herein

[0040] As shown in the accompanying drawings and described herein

[0041] As shown in the accompanying drawings and described herein

[0042] When the sleeve is mounted on the fixing frame 12, the sleeve is sleeved on the outside of the fixing frame 12 from the lower end to the upper end in the vertical direction, and the lower end of the fixing frame 12 is located in the sleeve, at this time, there is a gap between the fixing frame 12 and the inner wall of the sleeve, then the first nut 29 is rotated to move the first nut 29 downward along the first screw 28, so that the upper sleeve 30 also moves downward along the first screw 28, the upper support rod 31 articulated with the upper sleeve 30 also moves downward, the support plate 34 articulated with the upper support rod 31 also moves downward, the lower support rod 32 articulated with the support plate 34 also moves downward, and the lower sleeve 37 articulated with the lower support rod 32 also moves downward along the first screw 28, so that the spring 33 is compressed. In this process, the lower ends of the upper support rod 31 and the lower support rod 32 also drive the support plate 34 to move away from the first screw 28, the spacing between the plurality of support plates 34 is increased, that is, the support plates 34 are expanded, until the support plates 34 abut against the inner wall of the sleeve, so that the sleeve is mounted on the fixing frame 12.

[0043] Then, when the sleeve is dismounted from the fixing frame 12, the first nut 29 is rotated in the reverse direction to move the first nut 29 upward along the first screw 28, at this time, the compressed spring 33 is restored, so that the upper sleeve 30, the upper support rod 31, the support plate 34, the lower support rod 32 and the lower sleeve 37 all move upward, in this process, the lower ends of the upper support rod 31 and the lower support rod 32 also drive the support plate 34 to move close to the first screw 28, the spacing between the plurality of support plates 34 is reduced, that is, the support plates 34 are contracted, so that the support plates 34 are separated from the inner wall of the sleeve, at this time, the fixing frame 12 can be removed from the sleeve, that is, the sleeve can be dismounted from the fixing frame 12.

[0044] The spring 33 has two functions: one is to support the upper sleeve 30, the upper support rod 31, the support plate 34, the lower support rod 32 and the lower sleeve 37, and the other is to expand the support plate 34 when the first nut 29 is rotated downward along the first screw 28, and the spring 33 is compressed to store energy, and when the first nut 29 is rotated upward along the first screw 28, the spring 33 is restored to release the stored energy, so that the upper sleeve 30, the upper support rod 31, the support plate 34, the lower support rod 32 and the lower sleeve 37 can move upward under the action of the spring 33, and in this process, the support plate 34 is contracted.

[0045] As can be seen, the fixing frame 12 can be detachably mounted on the sleeve, that is, when the support plate 34 is expanded to abut against the inner wall of the sleeve, the sleeve can be mounted on the fixing frame 12, and vice versa, when the support plate 34 is contracted to separate from the inner wall of the sleeve, the sleeve can be dismounted from the fixing frame 12. In this embodiment, the size of the expansion of the support plate 34 can be adjusted according to the size of the inner diameter of the sleeve, so that the fixing frame 12 can be applied to the installation of sleeves with different inner diameters.

[0046] The support plate 34 is an arc-shaped plate matching the shape of the inner wall of the sleeve, when the support plate 34 abuts against the inner wall of the sleeve, the outer convex arc-shaped side of the support plate 34 abuts against the inner wall of the sleeve, and the inner concave arc-shaped side of the support plate 34 is hinged to the lower ends of the upper support rod 31 and the lower support rod 32. In order to prevent the support plate 34 from damaging the sleeve when abutting against the sleeve, a flexible pad 35 can be arranged on the outer convex arc-shaped side of the support plate 34.

[0047] As shown in Figure 2 The portable sleeve positioning tool of the present application, wherein the positioning member 1 comprises a first vertical side plate 3, a second vertical side plate 4 and a horizontal plate 2, the first vertical side plate 3 and the second vertical side plate 4 are arranged vertically, the first vertical side plate 3 is connected perpendicularly to the second vertical side plate 4, the horizontal plate 2 is connected between the top portions of the first vertical side plate 3 and the second vertical side plate 4, the upper surface of the horizontal plate 2 is provided with angle graduation lines, the center of the angle graduation lines is located on the intersection line of the first vertical side plate 3 and the second vertical side plate 4, the intersection position of the horizontal plate 2 and the first vertical side plate 3 shows 0 degree, the intersection position of the horizontal plate 2 and the second vertical side plate 4 shows 90 degree, and the horizontal plate 2 is a sector with a central angle of 90 degrees.

[0048] As shown in Figure 1 , 2 , 9, 14, 15, the connecting member 5 comprises a connecting bolt 17, the shank of the connecting bolt 17 is vertically provided with an indicating arrow 18, the straight ruler 6 is provided with a sliding groove 8 arranged along the length direction, the shank of the connecting bolt 17 is threadedly connected to the upper surface of the horizontal plate 2 after passing through the sliding groove 8 of the straight ruler 6, the axis of the connecting bolt 17 coincides with the intersection line of the first vertical side plate 3 and the second vertical side plate 4, and the indicating arrow 18 is clamped in the sliding groove 8 of the straight ruler 6, when the straight ruler 6 is horizontally rotated around the axis of the connecting bolt 17, the angle graduation lines can record the angle rotated by the straight ruler 6 relative to the first vertical side plate 3 or the second vertical side plate 4.

[0049] Since the 0 degree of the angle graduation lines on the horizontal plate 2 starts from the position where the horizontal plate 2 intersects with the first vertical side plate 3, and the 90 degree ends at the position where the horizontal plate 2 intersects with the second vertical side plate 4, and the center of the angle graduation lines is located on the intersection line of the first vertical side plate 3 and the second vertical side plate 4, and the axis of the connecting bolt 17 coincides with the intersection line of the first vertical side plate 3 and the second vertical side plate 4, i.e. the connecting bolt 17 is located at the center of the angle graduation lines, thus, when the straight ruler 6 is horizontally rotated around the axis of the connecting bolt 17, since the indicating arrow 18 is clamped in the sliding groove 8 of the straight ruler 6, then the connecting bolt 17 and the indicating arrow 18 thereon synchronously rotate with the straight ruler 6, and the construction personnel can see the size of the angle graduation lines pointed by the indicating arrow 18 from the sliding groove 8 of the straight ruler 6, i.e. the indicating arrow 18 can point to the angle rotated by the straight ruler 6.

[0050] As Figure 1 、 3 -8、11-13, wherein the first locking member 11 comprises a first locking bolt 13 and a first locking nut 15, a first clamping block 14 is vertically fixed on the shank of the first locking bolt 13, the first clamping block 14 abuts against the head of the first locking bolt 13, the upper end of the first shank 28 is threadedly connected with a first connecting cylinder 27, the shank of the first locking bolt 13 is sequentially threaded through the sliding slot 8 of the ruler 6 and the first locking nut 15 from top to bottom and is then threadedly connected in the cylinder cavity of the first connecting cylinder 27, the ruler 6 abuts between the head of the first locking bolt 13 and the first locking nut 15, and the first clamping block 14 is clamped in the sliding slot 8 of the ruler 6.

[0051] When the upper end of the first shank 28 is installed on the ruler 6 through the first locking member 11, the shank of the first locking bolt 13 is threaded through the ruler 6 from top to bottom, and then the first locking nut 15 is screwed on the shank of the first locking bolt 13, and then the shank of the first locking bolt 13 is screwed in the cylinder cavity of the first connecting cylinder 27 (in this process, the first clamping block 14 is not clamped in the sliding slot 8 of the ruler 6), and then the first locking member 11 and the fixing frame 12 are rotated relative to the ruler 6, and after the first clamping block 14 is aligned with the sliding slot 8 of the ruler 6, the first locking member 11 and the fixing frame 12 are moved downward relative to the ruler 6 until the first clamping block 14 is clamped in the sliding slot 8 of the ruler 6, and finally the first locking nut 15 is further tightened until the ruler 6 is clamped between the first locking nut 15 and the head of the first locking bolt 13. In this way, the upper end of the first shank 28 is installed on the ruler 6, that is, the fixing frame 12 is installed on the ruler 6 through the first locking member 11.

[0052] Then, when the upper end of the first shank 28 is detached from the ruler 6, the first locking nut 15 is loosened, and after there is a large enough gap between the first locking nut 15 and the head of the first locking bolt, the first locking member 11 and the fixing frame 12 are moved upward relative to the ruler 6, so that the first clamping block 14 is separated from the sliding slot 8 of the ruler 6, and then the shank of the first locking bolt 13 is unscrewed from the first connecting cylinder 27, so that the upper end of the first shank 28 is detached from the ruler 6, that is, the fixing frame 12 is detached from the ruler 6. If it is still desired to detach the first locking member 11 from the ruler 6, only the first locking nut 15 is unscrewed from the shank of the first locking bolt 13, and then the first locking bolt 13 is removed from the ruler 6.

[0053] After the fixing frame 12 is installed on the ruler 6 through the first locking member 11, the first clamping block 14 is engaged in the sliding groove 8 of the ruler 6. In this way, the ruler 6 is not easy to rotate relative to the screw of the first locking bolt 13, and the positioning accuracy of the final sleeve can be guaranteed.

[0054] like Figure 1 、 10 As shown, the portable casing positioning tool of the present invention, wherein the ruler 6 is detachably mounted with a support frame 10 through a second locking piece 9, and the support frame 10 is located below the ruler 6, and the support frame 10 includes a second screw 21 arranged vertically, and a support disc 22 is fixed on the second screw 21, and a plurality of support long rods 23 extending downward are hinged on the support disc 22, and the upper ends of the plurality of support long rods 23 are hinged on the support disc 22 at uniform intervals along the circumference of the support disc 22, and a support sleeve 26 is sleeved on the second screw 21 below the support disc 22, and a gap is left between the support sleeve 26 and the second screw 21, and a support short rod 24 is hinged between the support sleeve 26 and each support long rod 23, that is, the two ends of the support short rod 24 are respectively hinged on the support sleeve 26 and the support long rod 23, and the upper end of the second screw 21 is detachably mounted on the ruler 6 through the second locking piece 9.

[0055] When the support frame 10 needs to be opened, the support sleeve 26 is moved downward along the second screw rod 21, so that the support short rod 24 changes from an inclined state (one end of the hinged support sleeve 26 of the support short rod 24 is at the top, and one end of the hinged support long rod 23 is at the bottom) to a horizontal state, and the lower end of the support long rod 23 swings away from the second screw rod 21, that is, the support frame 10 is opened; conversely, when the support frame 10 needs to be folded, the support sleeve 26 is moved upward along the second screw rod 21, and the support short rod 24 changes from a horizontal state to an inclined state again, so that the lower end of the support long rod 23 swings toward the second screw rod 21, that is, the support frame 10 is folded. A baffle 25 can be provided at the bottom end of the second screw rod 21 to prevent the support sleeve 26 from slipping off the second screw rod 21 when moving downward along the second screw rod 21.

[0056] like Figure 1 、 3-8、10, wherein the second locking member 9 comprises a second locking bolt and a second locking nut, and a second clamping block is vertically fixed on the shank of the second locking bolt, and the second clamping block is in abutment with the head of the second locking bolt. The second locking member 9 is identical in structure to the first locking member 11. The upper end of the second shank 21 is threadedly connected with a second connecting cylinder 19, and the shank of the second locking bolt is threadedly connected in the cylinder cavity of the second connecting cylinder 19 in sequence from top to bottom after passing through the sliding slot 8 of the ruler 6 and the second locking nut, the ruler 6 is in abutment between the head of the second locking bolt and the second locking nut, the second clamping block is clamped in the sliding slot 8 of the ruler 6, and the second nut 20 is threadedly connected on the second shank 21 below the second connecting cylinder 19, and the second nut 20 is in abutment with the second connecting cylinder 19.

[0057] The upper end of the second shank 21 is detachably mounted on the ruler 6 by the second locking member 9 in the same way as the upper end of the first shank 28 is detachably mounted on the ruler 6 by the first locking member 11, that is, the support frame 10 is detachably mounted on the ruler 6 by the second locking member 9 in the same way as the fixing frame 12 is detachably mounted on the ruler 6 by the first locking member 11, and details are not repeated here.

[0058] After the support frame 10 is mounted on the ruler 6 by the second locking member 9, the second clamping block is clamped in the sliding slot 8 of the ruler 6, so that the ruler 6 is not easy to rotate relative to the shank of the second locking bolt, and the positioning accuracy of the last casing can be ensured.

[0059] The second nut 20 serves to limit the second connecting cylinder 19 and prevent the second connecting cylinder 19 from moving downward along the second shank 21.

[0060] The support frame 10 serves to support the ruler 6 (when supporting, the support frame 10 is in an open state), so as to stabilize the whole positioning tool, and the height of the support frame 10 can be adjusted so that the supported ruler 6 can be in a horizontal state. When adjusting the height of the support frame 10, only the second connecting cylinder 19 needs to be rotated to move upward or downward along the second shank 21, that is, the height adjustment can be realized, and after the second connecting cylinder 19 moves to the required position, the second nut 20 is rotated to abut against the second connecting cylinder 19.

[0061] The portable casing positioning tool, wherein the ruler 6 is provided as a plurality, the plurality of the ruler 6 is connected as a horizontally arranged ruler frame through the third locking piece 7, one of the ruler 6 in the ruler frame is detachably mounted on the positioning piece 1 through the connecting piece 5, at least one of the ruler 6 in the ruler frame is detachably mounted with the fixing frame 12 through the first locking piece 11, at least one of the ruler 6 in the ruler frame is detachably mounted with the support frame 10 through the second locking piece 9, any two adjacent rulers 6 in the ruler frame are a first ruler and a second ruler respectively, and the first ruler and the second ruler are connected through the third locking piece 7.

[0062] As shown in Figures 3-8 The portable casing positioning tool, wherein the third locking piece 7 comprises a third locking bolt and a third locking nut, a third clamping block is vertically fixed on the screw rod of the third locking bolt, and the third clamping block abuts against the head of the third locking bolt. The third locking piece 7 is completely identical in structure with the first locking piece 11.

[0063] The screw rod of the third locking bolt is sequentially threaded through the sliding groove 8 of the first ruler and the second ruler and is threadedly connected with the third locking nut, the head of the third locking bolt, the first ruler, the second ruler and the third locking nut abut against each other, and the third clamping block is clamped in the sliding groove 8 of the first ruler. That is to say, when the first ruler is located above the second ruler, the screw rod of the third locking bolt is sequentially threaded through the sliding groove 8 of the first ruler and the second ruler from top to bottom, and the third clamping block is clamped in the sliding groove 8 of the first ruler (the thickness of the third clamping block is not greater than the thickness of the first ruler), and then the third locking nut is screwed onto the third locking bolt until the third locking nut is tightened, at this time, the first ruler and the second ruler are clamped between the third locking nut and the head of the third locking bolt. Since the third clamping block is clamped in the sliding groove 8 of the first ruler, the first ruler is not easy to rotate relative to the screw rod of the third locking bolt.

[0064] Of course, when the second ruler is located above the first ruler, the screw rod of the third locking bolt is sequentially threaded through the sliding groove 8 of the second ruler and the first ruler and is threadedly connected with the third locking nut, the head of the third locking bolt, the second ruler, the first ruler and the third locking nut abut against each other, and the third clamping block is clamped in the sliding groove 8 of the second ruler. At this time, the way that the third locking piece 7 connects the second ruler located above and the first ruler located below is the same as the way that the third locking piece 7 connects the first ruler located above and the second ruler located below, which will not be described here.

[0065] As shown in Figure 1 , and in combination with Figure 14 , 15As shown, in this embodiment, two rulers 6 are provided: a long ruler and a short ruler. The long ruler is longer than the short ruler, measuring 1.0 m and 0.5 m respectively. Each ruler 6 has length markings on its long side and angle markings on both ends. The long ruler is the first ruler, and the short ruler is the second ruler. Of course, the reverse can also be used, with the short ruler representing the first ruler and the long ruler the second ruler.

[0066] One end of the long ruler is detachably mounted on the positioning member 1 through a connecting member 5, and the height of the positioning member 1 is 0.5m. The other end of the long ruler is detachably mounted on a support frame 10 through a second locking member 9. One end of the short ruler is connected to the long ruler through a third locking member 7, and the other end of the short ruler is detachably mounted on a fixing frame 12 through a first locking member 11.

[0067] The head of the first locking bolt 13 is provided with marking arrows 16 in two colors, for example, red and green. The two marking arrows 16 are perpendicular to each other and both pass through the center of the circle of the head of the first locking bolt 13. One of the marking arrows 16 is arranged vertically and correspondingly with the first clamping block 14, for example, the red marking arrow 16 is arranged vertically and correspondingly with the first clamping block 14. In this way, when engaging the first clamping block 14 with the chute 8 of the ruler 6, the construction worker only needs to align the red marking arrow 16 with the chute 8 of the ruler 6 to engage the first clamping block 14, which is convenient for operation. Similarly, the heads of the second and third locking bolts are also provided with marking arrows 16 in two colors.

[0068] As described above, the connector 5 includes a connecting bolt 17, which allows the ruler 6 to be detachably mounted on the positioning member 1. The head of the connecting bolt 17 is also provided with two colored marking arrows 16, for example, red and green. The two colored marking arrows 16 are perpendicular to each other and both pass through the center of the circle of the head of the connecting bolt 17. The marking arrow 16 of one color is arranged vertically corresponding to the indicator arrow 18 on the screw of the connecting bolt 17. This makes it easier for construction workers to read the angle of rotation of the ruler 6 relative to the positioning member 1.

[0069] like Figure 1As shown, during the construction process of the kitchen or bathroom, after the kitchen or bathroom floor steel bar binding is completed, the positioning piece 1 is fixed at a certain corner of the kitchen or bathroom, the first vertical side plate 3 and the second vertical side plate 4 of the positioning piece 1 are respectively abutted with two walls at the corner, then one end of the long ruler is connected to the horizontal plate 2 of the positioning piece 1 through the connecting bolt 17, the indicating arrow 18 on the connecting bolt 17 is clamped in the sliding groove 8 of the long ruler, the installation position of the sleeve relative to the positioning piece 1 is determined according to the construction drawing (for example, the deflection angle and distance of the installation position of the sleeve relative to the positioning piece 1 are determined, that is, the two-dimensional coordinates of the installation position of the sleeve relative to the positioning piece 1 in the horizontal plane can be determined), then the long ruler is rotated relative to the positioning piece 1, the long ruler is rotated through a certain angle (the construction personnel can read the rotated angle through the angle scale line on the positioning piece 1), then the support frame 10 is installed on the end of the long ruler away from the positioning piece 1 through the second locking piece 9, the support frame 10 supports the long ruler to keep it horizontal. Then one end of the short ruler is connected to the long ruler through the third locking piece 7 (since one end of the short ruler is located above the long ruler, the screw rod of the third locking bolt is sequentially inserted into the sliding groove 8 of the short ruler and the long ruler from top to bottom, and is threadedly connected with the third locking nut, the third clamping block is clamped in the sliding groove 8 of the short ruler and the third locking nut is tightened, so that the short ruler is connected to the long ruler), the short ruler and the long ruler together form a ruler frame, before connection, the short ruler is kept a certain distance from the positioning piece 1, which can be read from the length scale line of the long ruler. Then the fixing frame 12 is installed on the short ruler through the first locking piece 11, and the fixing frame 12 is kept a certain distance from the long ruler, which can be read from the length scale line of the short ruler. In this way, through the cooperation of the long ruler and the short ruler, the fixing frame 12 is deflected by a certain angle and distance relative to the positioning piece 1 (the angle is read through the angle scale line on the positioning piece 1, and the distance is read through the long ruler and the short ruler), at this time, the position of the fixing frame 12 coincides with the installation position of the sleeve on the construction drawing, that is, the fixing frame 12 reaches the installation position of the sleeve, then the sleeve is installed on the fixing frame 12, then the four corners of the sleeve are firmly fixed on the steel bar with steel wire binding, and the inside of the sleeve is filled with sawdust or sealed with adhesive tape. Then the sleeve is removed from the fixing frame 12, and then the entire positioning tool is removed from the kitchen or bathroom, so that the next step of construction of the kitchen or bathroom floor can be carried out. The construction personnel can move the positioning tool to the upper or lower kitchen or bathroom to perform the same operation to install the sleeve on this floor, so that the sleeves of the upper and lower kitchens or bathrooms can be accurately centered according to the installation position given by the construction drawing, and the problem of large deviation of the reserved positions of the sleeves from the given size of the construction drawing due to measurement errors and labeling errors during construction can be reduced. It can be seen that the present application belongs to a convenient tool.

[0070] It should be noted that when connecting one end of the long ruler to the positioning member 1 via the connecting bolts 17, a small portion of the wall above the positioning member 1 can be removed, for example, by digging a small pit in the wall to accommodate the connecting bolts 17 and the end of the long ruler connected to the positioning member 1. This ensures that the wall does not interfere with the connecting bolts 17 connecting the long ruler to the positioning member 1, and does not prevent the long ruler from rotating relative to the positioning member 1. When supporting the long ruler with the support frame 10, a pad can be laid above the steel bars in the kitchen or bathroom, and the support frame 10 can be placed on the pad. After the short ruler is connected to the long ruler, the two form a ruler frame, and both the long and short rulers remain horizontal.

[0071] Example 2

[0072] like Figure 16 As shown, the difference between this embodiment and the first embodiment is that the number of rulers 6, support frames 10 and fixing frames 12 is different, and two adjacent rulers 6 are connected not only by the third locking member 7 but also by the second locking member 9.

[0073] In this embodiment, a plurality of rulers 6 are provided, and the plurality of rulers 6 are connected to form a horizontally arranged ruler frame via a second locking member 9 and a third locking member 7. One ruler 6 in the ruler frame is detachably mounted on the positioning member 1 via a connecting member 5. A fixing frame 12 is detachably mounted on at least one ruler 6 in the ruler frame via a first locking member 11. A supporting frame 10 is detachably mounted on at least one ruler 6 in the ruler frame via a second locking member 9. Any two adjacent rulers 6 in the ruler frame are a first ruler and a second ruler. At least one pair of the first ruler and the second ruler are connected via a second locking member 9. The supporting frame 10 is connected to the second locking member 9 connecting the first ruler and the second ruler. The remaining pairs of first rulers and the second rulers are connected via a third locking member 7.

[0074] The number of rulers 6 is set to 8, the number of support frames 10 is set to 2, and the number of fixing frames 12 is set to 8. The number of long rulers and short rulers in the 8 rulers 6 can be determined according to actual conditions. The eight rulers 6 are connected to form a ruler frame via a second locking member 9 and a third locking member 7, and one end of one of the rulers 6 is mounted on the positioning member 1 via a connecting member 5.

[0075] When the two adjacent rulers 6 are connected by the second locking member 9, the two adjacent rulers 6 are the first ruler and the second ruler respectively, when the first ruler is above the second ruler, the screw rod of the second locking bolt passes through the sliding slot 8 of the first ruler and the second ruler from top to bottom in turn, and the second locking block is temporarily not allowed to be engaged in the sliding slot 8 of the first ruler, then the second locking nut is screwed on the second locking bolt, then the second locking bolt is rotated and screwed on the second connecting barrel 19 of the support frame 10, and finally the second locking block is engaged in the sliding slot 8 of the first ruler and the second locking nut is tightened.

[0076] When the second ruler is above the first ruler, the way of connecting the two rulers 6 and the support frame 10 by the second locking member 9 is the same as the above-mentioned way of connecting when the first ruler is above the second ruler, which will not be repeated here.

[0077] In this embodiment, the way of connecting the adjacent first ruler and the second ruler by the third locking member 7 is the same as the way of connecting the adjacent first ruler and the second ruler by the third locking member 7 in the first embodiment, which will not be repeated here.

[0078] In this embodiment, the eight rulers 6 are connected into a horizontally arranged ruler frame by the second locking member 9 and the third locking member 7, of course, when connecting in detail, the first ruler 6 is first installed on the positioning member 1 by the connecting member 5, the first ruler 6 is turned relative to the positioning member 1 by a certain angle, then the remaining rulers 6 are spliced with the first ruler 6 according to the actual situation to form a horizontally arranged ruler frame. The number of support frames 10 can be determined according to the actual situation, and the installation position of the support frame 10 can also be adjusted according to the actual situation, as long as it can support the ruler frame and make it in a horizontal state. Then the fixing frame 12 can be installed on the ruler 6 by the first locking member 11, at this time the fixing frame 12 is deflected by a certain angle and distance relative to the positioning member 1 and comes to the installation position of the sleeve, then the sleeve can be installed on the fixing frame 12. The subsequent construction method is the same as that of the first embodiment, which will not be repeated here.

[0079] As can be seen, the number of rulers 6, support frames 10 and fixing frames 12 in the present application can be randomly matched according to the actual situation, as long as the sleeve can be installed at the position shown on the construction drawing. In the specific use of the present application, the arrangement path of the positioning tool can be drawn on the construction drawing first to determine the number of rulers 6 (how many long rulers and short rulers are needed), the number of support frames 10 and the number of fixing frames 12, then the positioning tool can be installed according to the arrangement path drawn on the construction drawing.
