[0024] The present invention will now be described and explained in detail with reference to the accompanying drawings.

[0025] Example 1

[0026] like Figure 1-3 As shown, the portable pipe positioning and opening device includes a fixed sliding bracket. Pipe clamping mechanisms are fixedly installed on both sides of the bottom end of the fixed sliding bracket. The pipe clamping mechanisms hold a pipe 6. The pipe clamping mechanisms include a C-shaped retaining ring 3 and a C-shaped retaining ring 4, which are connected by a wing bolt 5. The openings of the C-shaped retaining rings 3 and 4 are opposite to each other. The opposite sides of the C-shaped retaining rings 3 and 4 are clamped onto the outer surface of the pipe 6. An opening device 7 is slidably installed through the middle of the fixed sliding bracket. The opening device 7 is used to open a hole in the pipe 6.

[0027] The fixed sliding support is made of square or round steel pipe; the bottom of the hole opener 7 is equipped with a drill bit; during construction, C-type retaining ring 1 3 and C-type retaining ring 2 4 are installed on the pipe 6 to form a circle. Before clamping C-type retaining ring 1 3 and C-type retaining ring 2 4 onto the outer surface of the pipe 6, the hole opening position should be located first. Slide the hole opener 7, align the drill bit of the hole opener 7 with the hole opening position, and after checking that the position and angle are accurate, tighten the wing bolt 5 to clamp C-type retaining ring 1 3 and C-type retaining ring 2 4 onto the outer surface of the pipe 6.

[0028] By setting a fixed sliding bracket to fix the sliding path of the hole opener 7, and using a pipe clamping mechanism to clamp and fix the fixed sliding bracket and the pipe 6, it is ensured that the sliding path of the hole opener 7 will not deviate, thus preventing slippage during the hole opening operation and improving stability. At the same time, the hole opening position and angle can be checked during the clamping and fixing process to ensure hole opening quality and improve hole opening efficiency. By adjusting the tightening length of the wing bolt 5, it can be adapted to pipes 6 of different diameters, expanding the scope of application.

[0029] The fixed sliding bracket includes a horizontally arranged crossbar 1 and two vertically arranged columns 2. The two columns 2 are fixedly arranged at both ends of the crossbar 1, and two sets of pipe clamping mechanisms are fixedly arranged at the bottom ends of the two columns 2. The bottom ends of the two columns 2 are fixedly connected to the center of two C-shaped retaining rings 3 by welding. Both columns 2 serve as the sliding track of the hole opener 7.

[0030] A circular retaining ring 9 is fixedly fitted on the outer surface of the hole opener 7, and two connecting rods 8 are fixedly installed on both sides of the circular retaining ring 9 in conjunction with two columns 2.

[0031] Each of the two connecting rods 8 has a slider 10 fixedly mounted at the end away from the circular retaining ring 9. The two sliders 10 are slidably connected to the outer surfaces of the two columns 2 respectively. The two connecting rods 8 are fixedly connected to the two sliders 10 by welding. The sliders 10 and the fixed sliding bracket are made of the same material. The inner diameter of the slider 10 is 3mm larger than the diameter of the column 2, which can ensure that the slider 10 slides freely along the column 2.

[0032] A round steel bar 11 is fixedly installed at the middle of the top of the hole saw 7. A bolt hole is opened in the middle of the crossbar 1. The round steel bar 11 passes through and is slidably connected to the bolt hole. The diameter of the bolt hole is 2mm larger than the diameter of the round steel bar 11. The length of the round steel bar 11 should be sufficient to meet the distance of sliding hole opening of the hole saw 7.

[0033] A hand handle 12 is fixedly installed at the top of the round steel 11, and the hand handle 12 is in the shape of a ring.

[0034] A handle 13 is fixedly installed on one side of the hole opener 7, and the handle 13 and the fixed sliding bracket are arranged vertically. The handle 13 facilitates the movement of this device, and the operator holding the handle 13 makes the hole opener 7 more convenient and labor-saving during the hole opening operation.

[0035] Both ends of the C-type retaining ring 4 have bolt holes 2, and the diameter of the bolt holes 2 is larger than the diameter of the wing bolt 5. The diameter of the bolt holes 2 is 5mm larger than the diameter of the wing bolt 5.

[0036] The C-type retaining ring 3 has two U-shaped grooves at its two ends, which are respectively fitted with two bolt holes 2. The width of the U-shaped groove is greater than the diameter of the wing bolt 5, and the width of the U-shaped groove is less than the diameter of the bolt hole 2. The width of the U-shaped groove is 3mm larger than the diameter of the wing bolt 5. During construction, the wing bolt 5 is slid into the U-shaped groove and tightened with a nut to fix it.

[0037] A stop block 14 is provided at the bottom of the wing bolt 5 to prevent the wing bolt 5 from slipping. The stop block 14 is located between the C-type retaining ring 3 and the C-type retaining ring 4. After the wing bolt 5 passes through the bolt hole 2 of the C-type retaining ring 4, the stop block 14 is threaded onto the outer surface of the wing bolt 5 near the end of the C-type retaining ring 4 to prevent the wing bolt 5 from slipping.
