Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example 1

[0023] like Figures 1-4 As shown, the utility model provides a technical solution: a drilling device that is convenient for replacing a drill bit, comprising: a connecting mechanism 1, the connecting mechanism 1 includes a transmission rod 11, one end of the transmission rod 11 is provided with a mounting mechanism 3, the mounting mechanism 3 includes a drill bit body, one end of the drill bit body is provided with a retaining slot seat 31, four sides of the retaining slot seat 31 are provided with positioning slots 34, four sides of the retaining slot seat 31 are provided with extension slots 37, and one side of each extension slot 37 is provided with a limiting slot 39, each limiting slot 39 is opened on the four sides of the retaining slot seat 31, and the four sides of the drill bit body are fixedly connected with a slot block 33, the outer surface of the slot block 33 is slidably connected to the inner wall of the positioning slot 34, and the outer surface of each slot block 33 is engaged with The inner wall of the extension groove 37 is connected to the inner wall of the positioning groove 34, and the inner wall of the positioning groove 34 passes through and is connected to one end of the drill body. One side of each slot block 33 is engaged with a block 38, and the outer surface of the block 38 is slidably connected to the inner wall of the limiting groove 39. One side of each block 38 is fixedly connected to the four sides of the handle 311, and the inner wall of the handle 311 is slidably and rotatably connected to one end of the retaining groove seat 31. The four sides of the handle 311 are fixedly connected to a slider 310, one side of each slider 310 is fixedly connected to one end of the spring 36, and the outer surface of each slider 310 is slidably connected to the inner wall of the slide groove 35, and each slide groove 35 is opened on the four sides of the retaining groove seat 31, and the inner wall of the slide groove 35 is fixedly connected to one end of the spring 36.

[0024] The screwdriver bit 33 is provided with a plurality of locking members 36 and a plurality of locking members 37, and the plurality of locking members 36 are provided with a plurality of locking members 38. When the card block 38 slides to a certain position in the limiting groove 39, the card block 38 can be locked into the predetermined slot of the card slot block 33. Since the slot of the card slot block 33 is in a relative direction to the position where the extension groove 37 slides, the card slot block 33 can be prevented from being separated from the predetermined slot of the extension groove 37. The rotary handle 311 provides a fixed effect for the card block 38, and the rotary handle 311 can slide and rotate in the predetermined slot of the retaining groove seat 31. During the rotation operation, the block 38 connected thereto will be driven to slide in the limiting groove 39 along the same trajectory. The handle 311 provides a fixed effect for the slider 310, and when the handle 311 slides, it will drive the slider 310 connected thereto to slide in the predetermined slot opened in the slide groove 35. Because one side of the slider 310 and one side of the slide groove 35 are each connected to one end of the spring 36, when the slider 310 slides, pressure will be applied to the spring 36, causing it to deform and provide a relative force.

[0025] Example 2

[0026] like Figure 1-Figure 2 As shown, one side of the transmission rod 11 is fixedly connected to the connecting seat 12, and one end of the connecting seat 12 is provided with a buffer mechanism 2, which includes a control slot tube 21. There are four control slot tubes 21, and the four control slot tubes 21 are fixedly connected to the bottom of the connecting seat 12. The inner wall of each control slot tube 21 is slidably connected to one end of the limiting rod 22, and one side of each limiting rod 22 is fixedly connected to one end of the spring piece 23, and one end of the spring piece 23 is fixedly connected to one side of the control slot tube 21, and one end of each limiting rod 22 is fixedly connected to the top of the retaining slot seat 31.

[0027] In this embodiment, the transmission rod 11 provides a retaining effect for the connecting seat 12, and the connecting seat 12 provides a retaining effect for the controlling slot tube 21, and the limiting rod 22 can slide in the predetermined slot opened by the controlling slot tube 21. One side of the limiting rod 22 and one side of the controlling slot tube 21 are respectively connected to one end of the spring piece 23. When sliding in the predetermined slot opened by the limiting rod 22 and the controlling slot tube 21, the limiting rod 22 and the controlling slot tube 21 will apply pressure to both ends of the spring piece 23 and cause it to deform, and one end of the limiting rod 22 is fixedly connected to the top of the retaining slot seat 31, so that when the retaining slot seat 31 is subjected to pressure, the pressure will be transmitted to the limiting rod 22.

[0028] Working principle:

[0029] like Figures 1-4 As shown, when drilling operation is required, the transmission rod 11 will drive the connecting seat 12 connected thereto and drive the retaining groove seat 31 and its connecting components through the connecting seat 12 to enable the drill body to drill holes. In the process of drilling, the vibration effect exerted on the drill body will be transmitted to the retaining groove seat 31 through its connecting components and then to the limiting rod 22. When the limiting rod 22 is subjected to pressure, it will slide in the control groove tube 21. During the sliding process of the limiting rod 22, the control groove tube 21 and the limiting rod 22 will apply pressure to the spring piece 23 to cause it to deform and provide relative force. When the drill body needs to be replaced, At this time, the handle 311 can be rotated. When the handle 311 is rotated, the retaining slot seat 31 connected to it will slide in the sliding slot 35 provided in the retaining slot seat 31 and exert pressure on the spring 36 to deform it and provide a relative force. During the sliding and rotating process of the handle 311, the clamping block 38 connected to it will slide in the limiting slot 39 provided in the retaining slot seat 31 until it is disconnected from the clamping block 33. When the clamping block 33 connected to the drill body is disconnected from the clamping block 38, it can slide out in the extension slot 37 and allow the drill body and the clamping block 33 to slide out as a whole through the positioning slot 34 provided in the retaining slot seat 31 for replacement.
