[0024] In order to make the purpose and technical solution of the utility model clearly and completely described, and the advantages more clearly understood, the embodiments of the utility model are further described in detail in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are part of the embodiments of the utility model, not all of the embodiments, and are only used to explain the embodiments of the utility model, and are not used to limit the embodiments of the utility model. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Embodiment 1

[0026] See also Figure 1-Figure 8 The utility model provides a technical solution: a convenient and quickly disassembled one-piece drilling drill, comprising a mounting seat 3, a drilling drill body 1 is plugged into the bottom of the mounting seat 3, two slide grooves a6 are provided inside the mounting seat 3, a moving block 7 is slidably connected to the inner wall of the slide groove a6, a fixing column 9 is installed at the bottom of the side close to the two moving blocks 7, a slider 4 is installed on the left and right sides of the drilling drill body 1, a slot 10 is provided on the side where the two sliders 4 are separated, and the fixing column 9 is plugged into the inner wall of the slot 10.

[0027] When in use, first move the two moving blocks 7 along the inner wall of the slide groove a6 toward the middle of the mounting seat 3, thereby driving the two fixing columns 9 to move toward the middle of the mounting seat 3. At this time, since slide blocks 4 are installed on both sides of the drilling drill body 1, and the two sliding blocks 4 are separated from each other. The side is provided with a card slot 10, the two moving blocks 7 are moved to drive the fixing column 9 to be inserted into the inner wall of the card slot 10, and then the drilling drill body 1 is stuck, thereby completing the installation of the drilling drill body 1. When disassembly is required, similarly, the two moving blocks 7 are moved to the two sides of the mounting seat 3 respectively to drive the fixing column 9 to disengage from the card slot 10, thereby facilitating the workers to disassemble the drilling drill body 1, thereby improving the efficiency of replacement.

[0028] Embodiment 2

[0029] On the basis of Example 1, in order to realize the movement of the two moving blocks 7 by turning the knob 2, a bidirectional screw 5 is inserted in the middle of the mounting seat 3, and a knob 2 is installed at the left end of the bidirectional screw 5, and the knob 2 is rotatably connected to the left side of the mounting seat 3; the bidirectional screw 5 passes through the left side of the mounting seat 3, and the right end of the bidirectional screw 5 is rotatably connected to the right side of the mounting seat 3, and the upper parts of the two moving blocks 7 are threadedly connected to the outside of the bidirectional screw 5, and the bidirectional screw 5 is driven to rotate by turning the knob 2, thereby driving the two moving blocks 7 to move along the inner wall of the slide groove a6, thereby facilitating the disassembly and assembly of the drilling drill body 1.

[0030] First, turn the knob 2 on the left side of the mounting base 3 to drive the bidirectional screw 5 to rotate. At this time, since the upper sides of the two moving blocks 7 are threadedly connected to the bidirectional screw 5, the rotation of the bidirectional screw 5 drives the two moving blocks 7 to move to the two sides of the bidirectional screw 5 respectively, thereby driving the two fixed columns 9 to disengage from the slot 10, so as to facilitate workers to disassemble the drilling bit body 1. Similarly, the reverse knob 2 drives the two moving blocks 7 to move toward the middle of the bidirectional screw 5, thereby driving the two fixed columns 9 to be inserted into the inner wall of the slot 10 on the upper side of the slider 4, thereby facilitating workers to install the drilling bit body 1.

[0031] Embodiment 3

[0032] On the basis of Example 2, in order to prevent the drilling drill body 1 from detaching from the mounting seat 3 after installation, a mounting groove 11 is opened on the upper right side of the mounting seat 3, and the inner wall of the mounting groove 11 is rotatably connected to the gear 8, and a sliding groove b13 is opened on the lower right side of the mounting seat 3, and the inner wall of the sliding groove b13 is slidably connected to a limiting plate 14. The limiting plate 14 plays a limiting role to prevent the blocking block 15 from being pushed out of the mounting groove 11 by the elastic force of the spring 12. The blocking block 15 is installed on one side of the limiting plate 14, and the spring 12 is installed on the other side of the limiting plate 14.

[0033] During disassembly and assembly, the rotation of the bidirectional screw 5 will drive the gear 8 to rotate on the inner wall of the mounting groove 11. At this time, since the inner wall of the slide groove b13 slides with the limit plate 14, and a clamping block 15 is installed on the top of the limit plate 14, and a spring 12 is installed on the bottom of the limit plate 14, during the rotation of the gear 8, the elastic force of the spring 12 pushes the limit plate 14 to move upward, and drives the clamping block 15 to be clamped in the tooth groove of the gear 8, so that after the gear 8 stops rotating, the gear 8 can be clamped by the clamping block 15, thereby preventing the gear 8 from rotating on the inner wall of the mounting groove 11, causing the drilling drill body 1 to separate from the mounting seat 3, so as to improve the stability after installation.

[0034] Embodiment 4

[0035] On the basis of Example 3, in order to improve the stability of the drilling drill body 1 after installation, the gear 8 is fixedly connected to the outer right side of the bidirectional screw 5, and the block 15 passes through the bottom wall of the installation groove 11 and is inserted into the bottom of the gear 8, so that the block 15 can easily clamp the tooth groove of the gear 8; the bottom end of the spring 12 is installed on the bottom wall of the slide groove b13, so as to facilitate the block 15 to move upward.

[0036] The elastic force of the spring 12 drives the limit plate 14 to move upward, and simultaneously drives the clamping block 15 to move upward, so that it passes through the installation groove 11 and is clamped in the tooth groove of the gear 8. When the gear 8 is rotated, the clamping block 15 is in contact with the bottom of the gear 8, thereby facilitating the clamping of the gear 8, so as to improve the stability of the drilling drill body 1 after installation.

[0037] In actual use, first move the two moving blocks 7 along the inner wall of the slide groove a6 toward the middle of the mounting seat 3, thereby driving the two fixing columns 9 to move toward the middle of the mounting seat 3. At this time, since slide blocks 4 are installed on both sides of the drilling drill body 1, and the two sliding blocks 4 are separated from each other. The side is provided with a card slot 10, the two moving blocks 7 are moved to drive the fixing column 9 to be inserted into the inner wall of the card slot 10, and then the drilling drill body 1 is stuck, thereby completing the installation of the drilling drill body 1. When disassembly is required, similarly, the two moving blocks 7 are moved to the two sides of the mounting seat 3 respectively to drive the fixing column 9 to disengage from the card slot 10, thereby facilitating the workers to disassemble the drilling drill body 1, thereby improving the efficiency of replacement.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
