DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0025] Referring to Figures 1-3 For an embodiment of the present utility model, it discloses an adjustable cutting tool. Specifically, the cutting tool includes a guiding body 1 and a cutting rod 2 inserted into the guiding body 1. By moving the cutting rod 2 up and down inside the guiding body 1, the operation of opening holes in the substrate can be realized:

[0026] A regulating seat 3 is slidably connected to the outside of the cutting rod 2, and the regulating seat 3 is locked and fixed to the cutting rod 2 through a locking member;

[0027] Among them, the lower end of the regulating seat 3 abuts against the upper end of the guiding body 1, and a limiting component 4 is further arranged between the cutting rod 2 and the guiding body 1. That is to say, in this embodiment, by sliding and abutting between the regulating seat 3 and the guiding body 1, the insertion depth of the cutting rod 2 can be controlled. In addition, the position of the regulating seat 3 is adjustable, so the control requirements of different depths can be met, and the cutting requirements of different objects can be satisfied.

[0028] In some embodiments, in the present utility model, the guiding body 1 includes a base 11 and a pipe fitting 12 arranged at the upper end of the base 11. Among them, an avoidance hole 13 opposite to the inner hole of the pipe fitting 12 is provided on the end surface of the base 11. The design of the avoidance hole 13 is used to provide a passing channel for the cutting rod 2. That is, when the cutting rod 2 moves downward, it can enter the substrate along the avoidance hole 13 to complete the hole-opening operation.

[0029] Furthermore, in this embodiment, at least one supporting part 14 is fixedly connected between the base 11 and the pipe fitting 12. The bottom end of the pipe fitting 12 is spaced from the upper end of the base 11 by a predetermined distance to form a discharge port 15. Specifically, the discharge port 15 in this embodiment is used to discharge mud and slag.

[0030] In some embodiments, in the present utility model, the limiting component 4 includes a positioning pin 41 inserted on the outside of the cutting rod 2. A spring 42 is fixedly connected between the positioning pin 41 and the receiving hole of the cutting rod 2. Specifically, in this embodiment, receiving holes are opened on both sides of the cutting rod 2. Two positioning pins 41 are provided and are respectively inserted into the receiving holes. Through the arrangement of the spring 42, the positioning pin 41 can be pressed.

[0031] Based on the above embodiments, in this embodiment, inwardly recessed edges 16 are provided at both the upper port and the lower port of the pipe fitting 12, and the cutting rod 2 slides along the inwardly recessed edges 16. Among them, at least a part of the positioning pin 41 abuts against the inwardly recessed edge 16, and the at least part is the part of the positioning pin 41 extending outside the cutting rod 2. That is to say, in this embodiment, the connection between the cutting rod 2 and the pipe fitting 12 can be realized by the positioning pin 41 abutting against the inwardly recessed edge 16 inside the pipe fitting 12, so as to prevent the cutting rod 2 from sliding out of the inside of the pipe fitting 12 when the cutting rod 2 moves upward.

[0032] Of course, when it is necessary to disassemble the above-mentioned cutting rod 2, the positioning pins 41 on both sides can be pressed to retract them into the receiving holes, and at this time, the entire cutting rod 2 can be taken out of the inside of the pipe fitting 12 to achieve the cleaning operation.

[0033] In order to realize the pressing of the positioning pin 41, in this embodiment, an unlocking window 17 and a positioning hole 18 are provided on the outer side of the pipe fitting 12. A fastening member is provided in the positioning hole 18. Preferably, in this embodiment, the unlocking window 17 is a rectangular opening, which needs to meet the requirement that the user's finger can reach in to realize the pressing of the positioning pin 41. In addition, the design of the positioning hole 18 is used to lock and fix the position of the cutting rod 2 through the fastening member in the positioning hole 18 when not in use, so as to keep a relatively locked state between the cutting rod 2 and the pipe fitting 12. Preferably, the fastening member in this embodiment is set as a bolt.

[0034] Of course, in order to realize the resetting of the cutting rod 2 after pressing, a compression spring 19 is further placed inside the pipe fitting 12 in this embodiment. The two ends of the compression spring 19 respectively abut between the lower inwardly recessed edge 16 of the pipe fitting 12 and the positioning pin 41. The design of the compression spring 19 is used to make the cutting rod 2 reset through the reverse thrust after pressing the cutting rod 2 downward. In addition, the top end of the compression spring 19 is arranged below the positioning pin 41, which can ensure the elasticity while not affecting the disassembly of the entire cutting rod 2.

[0035] It should be noted that in this embodiment, in order to accurately adjust the position of the adjusting seat 3, a scale mark 21 is arranged along the axial direction on the outer side of the cutting rod 2 in this embodiment, and the locking member is a locking bolt threadedly connected to the adjusting seat 3.

[0036] In summary, in this embodiment, by adopting the design of the guiding body 1, the insertion guiding of the cutting rod 2 can be realized, and the stability of the insertion direction of the cutting rod 2 can be maintained. Secondly, a slidable adjusting seat 3 is arranged on the outer side of the cutting rod 2, and the position of the adjusting seat 3 can be adjusted according to the requirement of the opening depth. In this way, when the cutting rod 2 moves downward to open the hole, the insertion depth of the cutting rod 2 is controlled by the adjusting seat 3, so as to realize the adjustable insertion depth of the cutting rod 2. The overall structure design is simple, which optimizes the efficiency and convenience of the cutting operation.

[0037] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and should be covered by the protection scope of the present utility model.
