[0024] The end cover 4 is snap-fitted with the mounting port 7, and a liquid gap 11 is provided between the end cover 4 and the mounting port 7, and the liquid gap 11 is used to connect the infusion cavity and the external space, so that the coolant enters the infusion cavity through the infusion port 8 and is transported to the surface of the tool through the liquid gap 11 to cool the tool.

[0025] Specifically, Figure 4 As shown, the end cover 4 includes a blocking portion and a clamping portion distributed along the axial direction of the mounting body 1, the blocking portion and the clamping portion are both annular, the inner diameter of the blocking portion is smaller than the inner diameter of the clamping portion, and the clamping portion is used to clamp with the mounting port 7. When the clamping portion is clamped with the mounting port 7, there is a liquid gap between the inner surface of the blocking portion close to the mounting body 1 and the surface of the mounting port 7, and the liquid gap is respectively connected with the infusion cavity and the external space, so that the coolant enters the infusion cavity through the infusion port 8 and is transported to the surface of the tool by the liquid gap 11 to cool the tool.

[0026] The present application provides a tool installation device capable of discharging water from the end face, wherein an installation body is installed inside a tool handle, and an infusion cavity is formed between the installation body and the tool handle, the installation body comprises an installation portion and an elastic fixing portion, and the installation portion and the elastic fixing portion are sequentially connected along a first direction to form an installation cavity; the elastic fixing portion has an installation port at one end away from the installation portion, which is used to install the tool and is deformed by force when the installation body is installed inside the tool handle to lock the tool, and the elastic fixing portion is circumferentially provided with an infusion port, which is used to connect the installation cavity and the infusion cavity; the installation portion has an injection port at one end away from the elastic fixing portion, which is used to inject coolant into the installation cavity; the end cover is snap-fitted with the installation port, and a liquid gap is provided between the end cover and the installation port, and the liquid gap is used to connect the infusion cavity and the external space, so that the coolant enters the infusion cavity through the infusion port and is transported to the tool surface through the liquid gap to cool the tool. This device ensures the cooling effect of the tool cutting area by discharging water at the end face, and when the tool mounting device equipped with the tool is installed in the tool handle, the elastic fixing part is deformed by the circumferential clamping force of the tool handle to clamp tools of different diameters, thereby effectively reducing costs.

[0027] In a preferred embodiment, the elastic fixing portion 3 includes a plurality of elastic units 12, and the elastic units 12 are uniformly distributed in sequence along the circumference of the mounting body 1, and there is an installation gap 13 between adjacent elastic units 12, and the installation gap 13 is used to provide an escape space for the elastic unit 12 when the elastic fixing portion 3 is deformed. The elastic fixing portion 3 is provided with a through hole on the circumferential side surface close to the mounting portion 2, and the through hole is connected with the installation gap 13 to form the infusion port 8.

[0028] Specifically, Figure 2 As shown, the elastic fixing portion 3 includes a plurality of elastic units 12, and the cross-section of the plurality of elastic units 12 is a fan-shaped ring; preferably, the number of the elastic units 12 is four, wherein the number of the elastic units 12 may also be other numbers, and different adjustments may be made according to specific circumstances, which are not specifically limited here. The ends of the four elastic units 12 close to the mounting portion 2 are integrally formed with the mounting portion 3, and the four elastic units 12 are uniformly distributed in sequence along the circumference of the mounting body 1; the ends of the four elastic units 12 away from the mounting portion 2 jointly form the mounting port 7, and the mounting port 7 is used to install the tool.

[0029] There is the same installation gap 13 between adjacent elastic units 12. When the installation body 1 is installed inside the knife handle, the knife handle applies a circumferential force to the multiple elastic units 12 of the installation body 1 along the radial direction of the installation body 1 to cause deformation; when the end cover 4 is installed on the installation port 7, it is also necessary to apply a circumferential force to the multiple elastic units 12 of the installation body 1 to cause deformation; in both cases, the elastic fixing portion 3 will shrink inward, and the spacing between the four elastic units 12 will decrease. The installation gap 13 is to provide an escape space.

[0030] The elastic fixing portion 3 is provided with a through hole on the circumferential side surface close to the mounting portion 2 , one end of the mounting gap 13 is connected to the through hole to form the infusion port 8 , and the other end of the mounting gap 13 extends along the axial direction of the mounting body 1 to divide the mounting body 1 into four elastic units 12 .

[0031] In a preferred embodiment, an annular protrusion 15 is circumferentially provided on the inner wall of the end cover 4, and an annular groove 14 is provided on the circumferential outer wall of one end of the elastic unit 12 close to the end cover 4, so that when the elastic fixing part 3 is subjected to force and each elastic unit 12 is deformed circumferentially, the elastic unit 12 can enter the interior of the end cover 4 through the opening of the end cover 4, and when the circumferential external force is eliminated, the elastic unit 12 causes the annular protrusion 15 to engage with the annular groove 14 under the action of the elastic restoring force.

[0032] Specifically, Figure 4 As shown, the inner wall of the clamping portion of the end cover 4 is provided with an annular protrusion 15 along the circumferential direction, and the annular protrusion 15 includes an annular first side wall 16 parallel to the inner wall of the end cover 4, and the elastic unit 12 and one end away from the mounting portion 2 together form the mounting port 7, and the mounting port 7 is provided with an annular groove 14 on the circumferential outer wall of one end close to the end cover 4. When the elastic fixing part 3 is in a natural state, the outer diameter of the elastic fixing part 3 is larger than the inner diameter of the annular first side wall 16, and the elastic fixing part 3 cannot be directly inserted into the end cover 4 and clamped with the end cover. At this time, it is necessary to apply external force to the elastic fixing part 3 in a circumferential direction to make the elastic unit 12 shrink and deform inwardly, until the outer diameter of the deformed elastic fixing part 3 is smaller than the inner diameter of the first side wall 16, and then place the mounting port 7 in the end cover 4 so that the annular groove 14 is opposite to the annular protrusion 15, and then remove the external force applied to the elastic fixing part 3 in a circumferential direction, and the elastic unit 12 recovers the deformation under the action of its own elastic restoring force to make the end cover 4 clamped with the mounting port 7.

[0033] In a preferred embodiment, the annular protrusion 15 includes an annular first side wall 16 parallel to the inner wall of the end cover 4, the annular groove 14 includes an annular second side wall 17 parallel to the outer wall of the mounting body 1, the outer diameter of the mounting body 1 is greater than the diameter of the annular first side wall 16, and when the annular protrusion 15 is engaged with the annular groove 14, there is a gap between the annular second side wall 17 and the annular first side wall 16.

[0034] Specifically, Figure 4 As shown, the annular protrusion 15 includes an annular first side wall 16 parallel to the inner wall of the end cover 4, and the annular groove 14 includes an annular second side wall 17 parallel to the outer wall of the mounting body 1; in a natural state, the outer diameter of the mounting body 1 is larger than the diameter of the annular first side wall 16, and the elastic fixing portion 3 cannot be directly inserted into the end cover 4 and clamped with the end cover. At this time, it is necessary to apply an external force to the elastic fixing portion 3 in a circumferential direction so that the elastic unit 12 shrinks and deforms toward the inside and is inserted into the end cover 4. After the external force is removed, the elastic unit 12, under the action of its own elastic restoring force, makes the annular protrusion 15 clamped with the annular groove 14, and there is a gap between the annular second side wall 17 and the annular first side wall 16. If the diameter of the tool installed between the elastic units 12 is smaller than the diameter of the elastic fixing part 3 when the annular protrusion 15 is engaged with the annular groove 14, the tool can be directly inserted between the elastic units 12, and the elastic fixing part 3 will not be deformed; if the diameter of the tool installed between the elastic units 12 is larger than the diameter of the elastic fixing part 3 when the annular protrusion 15 is engaged with the annular groove 14, when the tool is inserted into the elastic fixing part 3, the tool applies an outward expansion force along the radial direction of the elastic fixing part 3, so that the elastic unit 12 moves outward, the annular second side wall 17 and the annular first side wall 16 are close to each other, and the gap between the annular second side wall 17 and the annular first side wall 16 is used to provide an avoidance space for the movement of the elastic unit 12 at this time.

The end cap 4 with the sealing gasket 9 installed is clamped with the mounting body 1 and then installed in the knife handle, and the sealing gasket 9 abuts against the end face of the knife handle close to the mounting port 7, so that the sealing gasket 9 seals the gap between the knife handle and the end cap 4.

[0037] In a preferred embodiment, the injection port is an injection through hole 5 axially arranged along the mounting body 1, and a limiting member 6 is installed in the injection through hole 5.

Rotating the limiter 6 can make the limiter 6 move axially along the installation body 1 inside the installation cavity. When the tool is installed inside the installation body 1, one end of the tool abuts against the limiter 6, so that the limiter 6 limits and adjusts the installation position of the tool. The limiter 6 is provided with a first liquid passage extending in the axial direction, so that the coolant enters the installation cavity from the injection through hole 5 through the first liquid passage, and the coolant is transported from the installation cavity to the tool surface through the liquid gap 11 and the liquid outlet through hole to cool the tool.

[0039] In a preferred embodiment, the inner surface of the injection hole 5 is provided with threads, and the limit member 6 includes two connecting parts and two dividing parts arranged opposite to each other, and the connecting parts and the dividing parts are distributed in sequence around the axis of the limit member 6, and the two connecting parts are arc-shaped with a diameter matching the diameter of the injection hole 5 and have threads on their outer surfaces.

The coolant enters the installation cavity from the liquid injection hole 5 through the first liquid opening and the second liquid opening, so that the coolant is transported from the installation cavity to the tool surface through the liquid gap 11 to cool the tool.

[0041] In a preferred embodiment, the distance from the outer wall of the mounting body 1 to the axis of the mounting body 1 is a first distance, and the distance from the annular first side wall 16 to the axis of the mounting body 1 is a second distance. When the mounting body 1 is installed inside the tool handle and deformed under force to lock the tool, the first distance is greater than the second distance.
