Specific embodiments

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all of the embodiments.

[0030] Please refer to Figures 1 - 5 , the present application provides an anti-displacement drill bit including a fixing component 100 and an anti-displacement component 200.

[0031] Please refer to Figure 1 , 2 , 3 and 4, the fixing component 100 includes a connecting head 110, a rotating sleeve 120, a locking member 130 and a drill bit connecting rod 140. The rotating sleeve 120 rotates through the connecting head 110, the locking member 130 is arranged on the rotating sleeve 120, and the drill bit connecting rod 140 is inserted into the rotating sleeve 120.

[0032] It should be noted that by setting the protrusion 121 to be adapted to the groove 150, after the drill bit connecting rod 140 is installed, the drill bit connecting rod 140 can be powerfully driven to rotate by the rotating sleeve 120.

[0033] Among them, the locking member 130 includes a positioning screw 131 and a clamping block 132. The positioning screw 131 threadedly penetrates through the rotating sleeve 120, and the clamping block 132 is movably arranged at the end of the positioning screw 131. By setting the positioning screw 131 and the clamping block 132, the clamping block 132 is driven by rotating the positioning screw 131, and the drill bit connecting rod 140 is clamped and fixed by the contact of the arc-shaped clamping block 132, so the fixation is more stable.

[0034] In a specific implementation scheme, a receiving groove 122 is opened in the rotating sleeve 120, and the clamping block 132 is adapted to the receiving groove 122. By setting the receiving groove 122, it is used for the sliding of the clamping block 132.

[0035] In a specific implementation scheme, the drill bit connecting rod 140 includes a connecting handle 141 and a drilling head 142, and an anti-corrosion coating is provided on the surface of the drilling head 142.

[0036] Please refer to Figure 1 、 2 and 5, the anti-displacement assembly 200 includes a fixed rod 210, a sleeve 220, a positioning pin 240, a positioning disk 260 and a pressure sensor 270. The fixed rod 210 is arranged outside the connecting head 110, the sleeve 220 is slidably sleeved on the surface of the fixed rod 210, the positioning pin 240 penetrates through the sleeve 220, the positioning disk 260 is arranged at the bottom end of the sleeve 220, the drill bit connecting rod 140 passes through the positioning disk 260, and the pressure sensor 270 is arranged on the side of the positioning disk 260.

[0037] Among them, the sleeve 220 is provided with a plurality of positioning holes 222, and the plurality of positioning holes 222 are uniformly arranged. The positioning pin 240 threadedly penetrates through the positioning holes 222. By setting the plurality of uniformly arranged positioning holes 222, and the positioning pin 240 is screwed tightly into the corresponding positioning holes 222, the depth of each drilling can be determined.

[0038] Specifically, the positioning disk 260 is provided with a limiting opening 261, and the drill bit connecting rod 140 slidably penetrates through the limiting opening 261. By providing the limiting opening 261, it is used to limit the drilling of the drill bit connecting rod 140 and prevent displacement.

[0039] Among them, a plurality of pressure sensors 270 are symmetrically arranged on the side of the positioning disk 260, and the pressure sensors 270 are flush with the bottom surface of the positioning disk 260. By symmetrically arranging a plurality of pressure sensors 270, when the positioning disk 260 is pressed and fitted onto the object to be drilled, each pressure sensor 270 detects the pressure. During the drilling process, when the pressure detected by each pressure sensor 270 has a too large difference, an offset occurs and is corrected in time.

[0040] The working principle of the anti-displacement drill bit: During use, the drilling machine drives the rotating sleeve 120 to rotate, and the rotating sleeve 120 drives the drill bit connecting rod 140 to rotate. At the same time, the connecting head 110 of the drilling machine moves, and the connecting head 110 is pressed and fitted onto the item to be drilled. As the drill bit connecting rod 140 drills a hole, the limiting port 261 restricts the drilling of the drill bit connecting rod 140 to prevent displacement. At the same time, the connecting head 110 drives the fixed rod 210 to slide, and the fixed rod 210 slides along the sleeve 220, thereby guiding the stable linear movement of the drill bit connecting rod 140, effectively preventing deviation. At the same time, when the positioning disk 260 is pressed and fitted onto the object to be drilled, each pressure sensor 270 detects the pressure. During the drilling process, when the pressure detected by each pressure sensor 270 has a too large difference, an offset occurs and is corrected in time. By setting a plurality of uniformly arranged positioning holes 222, and screwing the positioning pins 240 into the corresponding positioning holes 222, the depth of each drilling can be determined, greatly improving the practicability.

[0041] It should be noted that the specific model specifications of the pressure sensors 270 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be elaborated in detail.

[0042] The power supply and principle of the pressure sensors 270 are clear to those skilled in the art and will not be elaborated here.

[0043] For those skilled in the art, it is obvious that this application is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of this application. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of this application is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in this application. Any reference signs in the claims should not be regarded as limiting the claimed rights.
