[0032] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention.

[0033] Example 1:

[0034] like Figures 1 to 9 As shown, a DM gun drill bit includes a drill rod 1 and a mounting rod 12. A connector 11 is provided above the drill rod 1. A first circular slot 13 is provided on the connector 11. A slot is provided below the first circular slot 13, and a second circular slot 132 is provided below the first circular slot. Drive slots are provided on both sides of the second circular slot 132, and a drive rod 234 is provided in the inner cavity of the drive slot. Two symmetrical wedge blocks 211 are provided in the inner cavity of the first circular slot 13. A circular mounting ring 131 is provided on the first circular slot 13. Two drill bits 121 are provided on the mounting rod 12. The mounting rod 12 and the two drill bits 121 are integrated. An mounting slot 3 is provided on the mounting rod 12. Movable slots are provided on both sides of the mounting slot 3. Multiple striking rods 341 are also provided in the inner cavity of the mounting slot 3. During installation, the mounting rod is placed in the first circular slot of the connector, which will squeeze the moving rod and drive the drive rod to move out of the drill rod, making operation easier. When the mounting rod is rotated to the corresponding position, the wedge block is inserted into the moving slot under the action of the auxiliary component, which stabilizes and limits the mounting rod to ensure reliable connection. At the same time, the movement of the wedge block will drive the striking rod to hit the inner wall of the mounting slot to produce a sound, indicating that the installation is complete, improving efficiency and accuracy, and making operation convenient.

[0035] Example 2:

[0036] The difference between the above embodiments and this embodiment is that: Figures 1 to 5 As shown, a DM gun drill bit has positioning slots on opposite sides of a first circular slot 13, and rectangular slots 2 at the bottom of the positioning slots. The two rectangular slots 2 are symmetrical to each other, and movable grooves 22 are formed on opposite side walls of the inner cavities of the two rectangular slots 2. In this configuration, the positions of the rectangular slots 2 and the movable grooves 22 are determined.

[0037] like Figures 1 to 5 As shown, in a specific embodiment, each movable slide groove 22 is symmetrical to each other, and a movable slider 221 is slidably arranged in the inner cavity of each movable slide groove 22. Each movable slider 221 is symmetrical to each other, and a movable plate 21 is arranged on one side wall opposite to each other of each movable slider 221. In this arrangement, the movable plate 21 can be moved horizontally.

[0038] like Figures 1 to 5 As shown, the two movable plates 21 are symmetrical to each other. A wedge-shaped block 211 is provided on one opposite side wall of each movable plate 21, and the two wedge-shaped blocks 211 respectively movably pass through the positioning slot. A first return spring 222 is provided on each opposite side wall of the two movable plates 21, with one end of each first return spring 222 located away from the movable plate 21 and positioned on the inner wall of the rectangular slot 2. In this configuration, the installation position of the wedge-shaped block 211 is determined, ensuring that the wedge-shaped block 221 can be reset.

[0039] like Figures 1 to 3 and Figures 5 to 6 As shown, further, a circular mounting plate 231 is provided inside the second circular slot 132. The circular mounting plate 231 is slidably mounted on the second circular slot 132. A moving rod 23 is provided above the circular mounting plate 231, and the moving rod 23 moves through the slot. A tension spring 232 is provided on the side wall opposite to the second circular slot 132, with its two ends respectively located on the side wall opposite to the second circular slot 132. In this configuration, the circular mounting plate 231 can be reset.

[0040] like Figures 1 to 3 and Figures 5 to 6 As shown, the bottom of the circular mounting plate 231 is further provided with two movably arranged swing arms 233, which are symmetrical to each other. A drive rod 234 is provided at each opposite end of the two swing arms 233. In this configuration, when the operator places the mounting rod 12 into the first circular slot 13 on the connector 11, the mounting rod 12 will press the moving rod 23 to move vertically downwards during placement. When the moving rod 23 moves vertically downwards, it will drive the circular mounting plate 231 to move vertically downwards. When the circular mounting plate 231 moves vertically downwards, it can drive the drive rod 234 to move via the swing arms 233, thus allowing the drive rod 234 to move off the drill rod 1.

[0041] Example 3:

[0042] The difference between the above embodiments and this embodiment is that: Figures 7 to 9As shown, a DM gun drill bit has guide grooves 311 on both opposite side walls of the mounting slot 3. A fixing plate 312 is placed between the two guide grooves 311. Two mutually symmetrical guide sliders 321 are slidably arranged inside the two guide grooves 311. Each guide groove 311 is symmetrical to the other two, and a positioning plate 32 is placed between each pair of guide sliders 321. In this configuration, the positioning plate 32 can move horizontally.

[0043] like Figures 7 to 9 As shown in the specific embodiment, a placement plate 322 is provided at the opposite end of the two positioning plates 32. The two placement plates 322 are symmetrical to each other and movably pass through the moving slot. The two placement plates 322 respectively engage with the wedge block 211. In this configuration, the positional relationship between the placement plate 322 and the wedge block 211 is determined.

[0044] like Figures 7 to 9 As shown, furthermore, each of the two placement plates 322 has a swing rod 333 on one opposite side wall. The two swing rods 333 are staggered and symmetrical. The ends of the two swing rods 333 away from the placement plate 322 are set on the turntable 332, and the two turntables 332 are symmetrical to each other. Rotating rods 33 are fixedly passed through the two turntables 332. The two rotating rods 33 are symmetrical to each other. Bearings 331 are set at both ends of the two rotating rods 33. Each bearing 331 is set in a mounting slot 3. Multiple concave fixing plates 34 are arranged in an arc shape on each of the two turntables 332. A striking rod is rotatably installed in the inner cavity of each concave fixing plate 34, and a torsion spring is installed at the rotation point. A torsion spring is installed between each bearing 331 and the turntable 332. In this configuration, when the wedge block 211 presses the placement plate 322 to move, the positioning plate 32 can push the swing rod 333 to rotate with the assistance of the rotating rod 33, bearing 331, and turntable 332. When the turntable 332 rotates, it can drive the concave fixing plate 34 to rotate. When the concave fixing plate 34 rotates, it can drive the internally installed striking rod 341 to rotate. Therefore, the striking rod 341 can hit the inner wall of the installation slot 3, thereby producing a sound to indicate to the worker that the drill bit 121 has been installed.

[0045] The implementation principle of a DM gun drill bit in this embodiment is as follows:

[0046] First, the worker places the mounting rod 12 into the first circular slot 13 opened on the connector 11. During the placement process, the mounting rod 12 will press the moving rod 23 to move vertically downward. When the moving rod 23 moves vertically downward, it will be able to drive the circular mounting plate 231 to move vertically downward. When the circular mounting plate 231 moves vertically downward, it can drive the driving rod 234 to move through the swing arm 233, thus allowing the driving rod 234 to move out of the drill rod 1.

[0047] Meanwhile, the operator rotates the mounting rod 12 until the wedge block 211 in the inner cavity of the first circular slot 13 aligns with the movable slot on the mounting rod 12. At this point, the wedge block 211 can move horizontally under the elastic force of the first return spring 222 and with the assistance of the movable slide 22, the movable slider 221, and the movable plate 21. Therefore, the wedge block 211 can press the placement plate 322 to move horizontally with the assistance of the positioning plate 32, the guide slide 311, and the guide slider 321. Thus, the wedge block can be inserted into the inner cavity of the movable slot, thereby limiting the mounting rod 12.

[0048] When the wedge block 211 presses the placement plate 322 to move, the positioning plate 32 pushes the swing rod 333 to rotate with the assistance of the rotating rod 33, bearing 331 and turntable 332. When the turntable 332 rotates, it can drive the concave fixing plate 34 to rotate. When the concave fixing plate 34 rotates, it can drive the internally installed striking rod 341 to rotate. Therefore, the striking rod 341 can hit the inner wall of the installation slot 3, thereby producing a sound to indicate to the worker that the drill bit 121 has been installed.
