[0022] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Example 1: Figures 1-4 As shown, the utility model provides a technical solution: a machine-clamped split gun drill, comprising a drill bit 1, a cutting blade 2 and a connecting sleeve 3, a limiting hole 4 is provided at the shank end of the drill bit 1, a limiting rod 5 is slidably connected to the inside of the connecting sleeve 3, a limiting disk 6 is fixedly installed on the surface of the limiting rod 5, a spring 7 is provided on the surface of the limiting rod 5, a rack 8 is slidably connected to the inside of the connecting sleeve 3, a rotating rod 9 is rotatably connected to the inside of the connecting sleeve 3, a gear 10 is fixedly installed on the surface of the rotating rod 9, one end of the limiting rod 5 is fixedly connected to a connecting plate 11, a handle 12 is fixedly installed on the side of the connecting plate 11, the limiting rod 5 is slidably connected to the limiting hole 4, one end of the spring 7 is fixedly connected to the side of the limiting disk 6, the other end of the spring 7 is fixedly connected to the inner side of the connecting sleeve 3, the rack 8 and the gear 10 are meshed with each other, one end of the rack 8 is fixedly connected to the side of the connecting plate 11, and an anti-slip groove 13 is provided on the surface of the handle 12.

[0025] In this embodiment, by pulling the handle 12, the connecting block drives the limit rod 5 to move backward, and at the same time the connecting plate 11 drives the rack 8 to move. Since the rack 8 and the gear 10 are engaged with each other, the gear 10 drives the rack 8 on the other side to move, and then the limit rod 5 will slide out from the inside of the limit hole 4. At this time, the drill bit 1 can be taken out from the inside of the connecting sleeve 3, so that the drill bit 1 can be quickly disassembled and replaced, so that the equipment can flexibly respond to different processing requirements, improve the adaptability of the production line, ensure that the most suitable drill bit 1 is always used during the processing, and avoid operational risks caused by problems with the drill bit 1.

[0026] Example 2: Figures 1-4 As shown, the surface of the drill bit 1 is provided with a card slot 14 and a card slot 2 15, the side of the cutting blade 2 is fixedly installed with a card block 16 and a card block 2 17, the side of the cutting blade 2 is threadedly connected with a fixed threaded rod 18 and a fixed threaded rod 2 19, the card block 16 and the card slot 14 are slidably connected, the card block 2 17 and the card slot 2 15 are slidably connected, the fixed threaded rod 18 is threadedly connected to the drill bit 1, and the fixed threaded rod 2 19 is threadedly connected to the drill bit 1.

[0027] In this embodiment, by using a tool to unscrew the fixed threaded rod 18 and the fixed threaded rod 2 19 from the inside of the drill bit 1, the cutting blade 2 can be separated from the drill bit 1. Therefore, when part of the cutting blade 2 is damaged, it is possible to directly replace a single one without replacing the main body, thereby reducing the replacement time and reducing the loss caused by replacing the entire drill bit 1.

[0028] The working principle of this embodiment is as follows: when the drill bit 1 needs to be replaced, the handle 12 is first pulled to cause the connecting block to drive the limiting rod 5 to move backward. The anti-slip groove 13 on the handle 12 improves the stability during pulling. At the same time, the connecting plate 11 drives the rack 8 to move. Since the rack 8 and the gear 10 are engaged with each other, the gear 10 drives the rack 8 on the other side to move, and then the limiting rod 5 will slide out from the inside of the limiting hole 4. At this time, the drill bit 1 can be taken out from the inside of the connecting sleeve 3, thereby realizing rapid disassembly and replacement of the drill bit 1, so that the equipment can flexibly respond to different processing requirements, improve the adaptability of the production line, ensure that the most suitable drill bit 1 is always used during the processing, and avoid operational risks caused by problems with the drill bit 1. The operator can use a tool to unscrew the fixed threaded rod 18 and the fixed threaded rod 2 19 from the inside of the drill bit 1. At this time, the cutting blade 2 can be separated from the drill bit 1, so that when part of the cutting blade 2 is damaged, it can be directly replaced individually without replacing the main body, thereby reducing replacement time and reducing the loss caused by replacing the entire drill bit 1.

[0029] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any other form. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
