[0024] The following description is only intended to disclose the present invention so that those skilled in the art can implement it. The embodiments in the following description are merely examples, and those skilled in the art will conceive of other obvious modifications. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other solutions that do not depart from the spirit and scope of the present invention.

[0025] Example 1:

[0026] A quick-connecting device for locking from top to bottom includes a handle 1, a blade body 2, a locking slider 10, and a limiting member 6.

[0027] like Figure 1 , Figure 4 , Figure 5 The handle 1 is divided into two parts, left and right. The left side is the connection part with the blade body 2, and the right side is the power connection part 16, which is used to connect with mechanical equipment. The power connection part 16 can be a triangular handle, square handle, or other handle types.

[0028] The left end of the tool holder 1 is provided with a centering drill mounting hole 14, and the outer circle of the tool holder 1 is provided with a bolt hole 5 for fixing the centering drill, which is used to install a bolt assembly to lock the centering drill.

[0029] The outer circle on the left side of the handle 1 is provided with a slider positioning groove 15, a convex positioning groove 4 and a plane 3. Two sets of convex positioning grooves 4 are provided, which can be evenly distributed on the circumference. In other embodiments, more than two sets can be provided. One set of slider positioning grooves 15 is provided. In other embodiments, multiple sets can be provided. The plane 3 is connected to the convex positioning groove 4. The plane 3 serves to prevent interference between the handle 1 and the convex 9 when the handle 1 enters the blade body 2.

[0030] The convex positioning groove 4 extends a certain length along the outer circumference of the tool holder 1. The slider positioning groove 15 is connected to the convex positioning groove 4. The slider positioning groove 15 is used to accommodate the locking slider 10. The limiting member 6 is used to limit the locking slider 10 in the slider positioning groove 15.

[0031] like Figure 3 , Figure 5 The slider positioning groove 15 includes a first positioning groove 7 and a second positioning groove 8 connected to each other. The first positioning groove 7 and the second positioning groove 8 are not collinear, that is, they have a certain tilt angle. When the blade body 2 is installed, the second positioning groove 8 provides clearance space for the locking slider 10. The first positioning groove 7 is connected to the protrusion positioning groove 4. After the protrusion 9 enters the protrusion positioning groove 4, one end of the locking slider 10 slides along the first positioning groove 7 to the protrusion positioning groove 4. The protrusion positioning groove 4 and the locking slider 10 respectively restrict the two sides of the protrusion 9.

[0032] The limiting member 6 includes a central cylinder disposed in the positioning groove 7. A platform 13 is formed by pressing the surface of the central cylinder. A long groove 11 for accommodating the central cylinder is provided on the locking slider 10. The diameter of the platform 13 is larger than the width of the long groove 11, so that the locking slider 10 can slide and is constrained in the slider positioning groove 15 by the platform 13.

[0033] like Figure 6 The locking slider 10 is provided with a handle 12, which facilitates the sliding control of the locking slider 10.

[0034] like Figure 2 One end of the cutter body 2 is provided with an annular cutting edge, and the inner wall of the other end is provided with two sets of protrusions 9, which are matched with the protrusion positioning groove 4.

[0035] When the handle 1 is connected to the tool body 2, the locking slider 10 is slid into the positioning groove 8 so that the locking slider 10 avoids the entry path of the protrusion 9. The protrusion 9 on the tool body 2 enters the protrusion positioning groove 4 from the plane 3. After rotating a certain angle, the protrusion 9 reaches the bottom position of the protrusion positioning groove 4. After the protrusion 9 is placed into the protrusion positioning groove 4, the torque transmission in the circumferential direction can be realized and the axial movement is restricted.

[0036] When the protrusion 9 enters the protrusion positioning groove 4, the locking slider 10 slides down and slides along the positioning groove 7 to the protrusion positioning groove 4, pressing against one side of the protrusion 9 to restrict the reverse movement in the circumferential direction. This can prevent the reverse inertial impact when power is lost, thus achieving circumferential restriction and axial connection. By physically restricting the reverse inertial impact of the tool when power is lost, the connection stability and safety factor during use are ensured.

[0037] When the knife handle 1 and the knife body 2 need to be released, the handle 12 is only moved to release the restriction, and the knife body 2 can be replaced at this time.

[0038] Embodiment 2:

[0039] Different from embodiment 1, in this embodiment, the locking slider 10 is detachably installed in the slider positioning groove 15. When the convex point 9 is installed to the set position in the convex point positioning groove 4, the locking slider 10 is installed, and the connecting member such as a buckle, a bolt or the like is used as the restriction member 6 to fix the locking slider 10 in the slider positioning groove 15.

[0040] Embodiment 3:

[0041] Different from embodiment 1, the restriction member 6 can also be arranged as a baffle opening at the top of the slider positioning groove 15, and the locking slider 10 is limited to slide inside the slider positioning groove 15 by the baffle.

[0042] It should be understood by those skilled in the art that the above description and the embodiments of the utility model shown in the drawings are only as examples and do not limit the utility model. The purpose of the utility model has been completely and effectively realized. The function and structural principle of the utility model have been displayed and explained in the embodiments, and the implementation of the utility model can be any deformation and modification without departing from the principle.
