They are flexible and high-efficiency automated machine tools, representing the development direction of modern machine tool control technology. They are typical mechatronic products. During the processing of numerical control machine tools, different types and sizes of tools need to be frequently replaced according to the processing requirements. Therefore, a tool management device is required to assist in the management of tools to facilitate the replacement and use of different tools.

[0011] Preferably, the selection device includes a rotating disk, a limiting push plate, a support column, a support arc frame, an extension inclined plate, a plugging rod, a pulling spring, a transverse sliding seat and a support sleeve. The rotating disk is rotatably installed on the bottom inner wall of the storage box through a bearing. The output end of the power motor penetrates through the storage box and is installed at the bottom of the rotating disk. The limiting push plate is installed on the top of the rotating disk through a bearing. A spiral elastic piece for automatic reset is installed on the outer side of the rotating pin at the bottom of the limiting push plate. The support column is installed on the top of the rotating disk and at a position clockwise to the limiting push plate. The support arc frame is installed on the top of the rotating disk and at the rear side of the inner end of the limiting push plate. The extension inclined plate is installed on the top of the rotating disk and at the rear side of the support arc frame. A plugging hole is opened at the bottom of the support seat. The pulling spring is installed on the top inner wall of the plugging hole. The top end of the plugging rod is inserted into the interior of the plugging hole. The bottom end of the pulling spring is installed at the top end of the plugging rod. The transverse sliding seat is installed on the outer wall of the plugging rod. The transverse sliding seat is slidably clamped with the transverse limiting chute. The support sleeve is rotatably installed on the outer wall of the plugging rod near the bottom end through a bearing.

[0012] Preferably, the cleaning device includes a toothed ring, a side plate, a toothed row, a diversion box, a cleaning strip and a collection box. The toothed ring is installed on the outer wall of the clamping cylinder seat. The side plate is installed on the inner wall of the storage box.

[0013] Preferably, the clamping groove is divided into two upper and lower cavities, and the opening of the upper cavity is larger than that of the lower cavity.

[0014] Preferably, the mounting seat is conical, the inclined chute is inclined, an inclined cut surface is opened at the bottom of the support seat, the bottom end of the support seat is inserted into the inclined chute through a side slider, and the clamping springs and clamping blocks are grouped in fours.

[0015] Preferably, the limiting push plate is inclined, the outer end of the extension inclined plate extends to the inside of the support sleeve, and the outer end of the limiting push plate extends to the outside of the support sleeve.

[0016] Preferably, the side of the cleaning strip away from the side plate is inclined upward, and the outer end of the bottom of the diversion box is inclined downward.

[0017] A management method for a machine tool tool management device for a numerical control machine tool includes the following steps:

[0018] First step: Control the power motor to drive the selection device to rotate. The selection device toggles the clamping device to move inward along the inclined chute. After the clamping device moves to the innermost position, the tool is inserted into the inside of the clamping groove through the top for storage. Multiple tools are respectively installed into different clamping grooves according to the same method.

[0019] Second step: During the use process, when a tool needs to be selected, control the power motor to rotate clockwise. The power motor drives the rotating disk to rotate clockwise, and the rotating disk drives the limit push plate to rotate clockwise. After the limit push plate contacts the support sleeve, it will deflect inward and cross over the support sleeve. When the limit push plate crosses over the support sleeve below the tool to be taken out, the selection work is completed.

[0020] Third step: When the tool needs to be sent out, control the power motor to rotate counterclockwise. At this time, after the limit push plate contacts the support sleeve, the limit push plate maintains an inclined state under the support of the support column. A force moving inward is applied by pushing the support sleeve through the limit push plate. The support sleeve moves inward along the surface of the limit push plate until it moves to the inside of the support arc frame and is clamped and supported. During the movement of the support sleeve, the insertion rod is driven to move inward. The insertion rod moves inward under the restrictive cooperation of the transverse sliding seat and the transverse limit chute. When the insertion rod moves inward, the support seat is driven to move inward. During the process of the support seat moving inward under the cooperation and restriction of the side slider and the inclined chute, it will also move upward. Thus, the clamping cylinder seat is driven by the support seat to move inward and upward, and the tool is lifted upward through the top opening of the storage box.

[0021] Fourth step: After use, the tool is inserted into the inside of the clamping groove from the top. When the tool is inserted into the inside of the clamping groove, it squeezes the clamping block to move outward and compresses the clamping spring. Thus, the tool is clamped and fixed through the cooperation of the clamping spring and the clamping block. Then, control the rotating disk to continue rotating counterclockwise. The rotating disk drives the support arc frame to rotate so that the support sleeve is separated from the support of the support arc frame. After the support sleeve moves to the surface of the extension inclined plate, the pulling spring applies a pulling force that makes the insertion rod and the support seat approach each other. The support seat will move outward under the restriction of the inclined chute. The lower end of the support seat, under the cooperation of the insertion rod, the support sleeve and the extension inclined plate, the support sleeve slowly moves outward along the surface of the extension inclined plate, improving the operation stability effect, and thus realizing the function of recycling and storing the tool.

[0022] In the fifth step, during the process of the support base moving outward along the inclined chute, the support base drives the toothed ring to move outward through the clamping cylinder base. Under the restriction of the toothed row, the toothed ring drives the clamping cylinder base to rotate. The clamping cylinder base drives the tool clamped inside it to rotate. The tool contacts the cleaning strip and rotates, so as to brush and clean the surface of the tool through the cleaning strip. The tool moves downward while moving outward, making the wiping of the cleaning strip more uniform. At the same time, the debris wiped by the cleaning strip approaches the side plate surface under the support of the cleaning strip, and then falls into the diversion box. Finally, it slides outward along the inside of the diversion box and falls into the collection box for storage, thus completing the removal, storage, and cleaning of the tool.

[0023] (III) Beneficial effects

[0024] The present invention provides a machine tool tool management device and management method for a numerical control machine tool. It has the following beneficial effects:

[0025] 1. By setting up a cleaning device, it can automatically wipe and clean the surface of the tool during the process of pushing out and storing the tool, thereby preventing debris from adhering to the surface of the tool and affecting the service life of the tool and the accuracy during subsequent processing. And the debris cleaned out will be automatically collected into the collection box along the diversion box, which is convenient for cleaning.

[0026] 2. Through the cooperation of the clamping device and the selection device, the selection device pushes the clamping device from the outside to the inside. When taking out the tool, the tools stored at different angles will all be pushed upward through the central position, so as to facilitate the taking of the tool and the clamping work of the numerical control machine tool, and it is convenient for the numerical control machine tool to install and store the tool at a fixed position, which is easy to use.

[0027] 3. Through the cooperation of the power motor and the selection device, when controlling the power motor to rotate clockwise, the selection work of the tool can be realized. When controlling the power motor to rotate counterclockwise, the pushing out work of the tool can be realized. When different-position tools are needed, first control the power motor to drive the selection device to rotate clockwise to the corresponding angular position, and then control the power motor to drive the selection device to rotate counterclockwise to push out the selected tool, thus reducing the difficulty of the selection operation.

[0028] 4. When installing the tool, it can be installed in sequence according to the order of using the tool, so that it can quickly distinguish the tools in sequence during processing and improve the processing efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0039] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0040] Please refer to Figures 1-9, the present invention provides a technical solution: a machine tool tool management device and management method for a numerically controlled machine tool, including a storage box 1, a clamping device 4 for clamping the tool, a selection device 6 for selecting the tool, and a cleaning device 7 for automatically cleaning the surface of the tool. An installation chassis 2 for installation and fixation is installed at the bottom of the storage box 1. An installation seat 3 is installed inside the storage box 1. A power motor 5 is installed at the bottom of the storage box 1. Above the installation seat 3, there is a clamping device 4 for clamping the tool. Inside the storage box 1 and at a position below the installation seat 3, there is a selection device 6 for selecting the tool. Inside the storage box 1 and at a position above the installation seat 3, there is a cleaning device 7 for automatically cleaning the surface of the tool. Inside the opening at the top of the storage box 1, a fan-shaped top cover plate 8 is installed through a hinge with an automatic reset function.

[0041] As shown in the attached Figures 2-6 , the installation seat 3 further includes an inclined chute 31, a communication opening 32, and a horizontal limit chute 33. The inclined chute 31 is opened at the top of the installation seat 3. The communication opening 32 is opened below the inclined chute 31. The horizontal limit chute 33 is horizontally opened at a position near the bottom inside the communication opening 32. The clamping device 4 and the selection device 6 are supported and installed through the installation seat 3.

[0042] As shown in the attached Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 8 and Figure 9 , the clamping device 4 includes a support seat 41, a side slider 42, a clamping cylinder seat 43, a clamping spring 44, a clamping block 45, and a clamping groove 46. The side slider 42 is opened at a position near the bottom on the outer surface of the support seat 41. The bottom end of the support seat 41 is slidably clamped inside the inclined chute 31 through the side slider 42. The side slider 42 is an inclined square block. Through the cooperation of the side slider 42 and the inclined chute 31, the support seat 41 can move along the inclined direction and can maintain a vertical state during movement. The clamping cylinder seat 43 is rotatably installed at the top of the support seat 41 through a bearing. The clamping groove 46 is opened at the top of the clamping cylinder seat 43. A clamping opening is opened on the inner wall of the clamping groove 46. The clamping spring 44 is installed inside the clamping opening. The clamping block 45 is installed inside the clamping opening. The inner end of the clamping spring 44 is installed with the clamping block 45. The tool is clamped and fixed through the cooperation of the clamping spring 44 and the clamping block 45, so that the tool can be stably stored above the clamping cylinder seat 43. A sponge block for wiping the part of the tool inserted into it is pasted on the inner wall of the clamping groove 46.

[0043] As shown in the attached Figure 3 , Figure 4 and Figures 7-9As shown, the selection device 6 includes a rotating disk 61, a limiting push plate 62, a support column 63, a support arc frame 64, an extension inclined plate 65, a plugging rod 66, a pulling spring 67, a transverse sliding seat 68, and a support sleeve 69. The rotating disk 61 is rotatably installed on the bottom inner wall of the storage box 1 through a bearing. The output end of the power motor 5 penetrates the storage box 1 and is installed at the bottom of the rotating disk 61. The limiting push plate 62 is installed on the top of the rotating disk 61 through a bearing. A spiral elastic piece for automatic reset is installed on the outer side of the rotating pin at the bottom of the limiting push plate 62. The support column 63 is installed on the top of the rotating disk 61 and is located at the clockwise side of the limiting push plate 62. The support arc frame 64 is installed on the top of the rotating disk 61 and is located at the rear side of the inner end of the limiting push plate 62. The inner side wall of the support arc frame 64 is arc-shaped, and the radian of the inner side wall of the support arc frame 64 is equal to the radian of the outer wall of the support sleeve 69, so that the support sleeve 69 can be kept stable without shaking when stuck inside the support arc frame 64, which is convenient for clamping the pushed-out tool and for fixing and storing the tool. The extension inclined plate 65 is installed on the top of the rotating disk 61 and is located at the rear side of the support arc frame 64. A plugging hole is opened at the bottom of the support seat 41. The pulling spring 67 is installed on the top inner wall of the plugging hole. The top end of the plugging rod 66 is inserted into the inside of the plugging hole. The bottom end of the pulling spring 67 is installed at the top end of the plugging rod 66. The transverse sliding seat 68 is installed on the outer wall of the plugging rod 66. The transverse sliding seat 68 is slidably clamped with the transverse limiting chute 33. The transverse sliding seat 68 is a cross-shaped slider, and the plugging rod 66 is supported by the transverse sliding seat 68. The support sleeve 69 is rotatably installed on the outer wall of the plugging rod 66 near the bottom end through a bearing. An anti-detachment cap is opened at the bottom end of the plugging rod 66, and the bottom of the support sleeve 69 is supported by the anti-detachment cap to prevent the support sleeve 69 from falling off and improve the operating stability. The power motor 5 is a stepping motor, which can accurately control the rotation angle. The rotation angle of the power motor 5 is controlled numerically. When different-position tools are needed, first control the power motor 5 to drive the selection device 6 to rotate clockwise to the corresponding angular position, and then control the power motor 5 to drive the selection device 6 to rotate counterclockwise to push out the selected tool. The tool model stored at the position corresponding to the rotation angle of the power motor 5 is uploaded in advance. When a specified model of tool is needed, it can be quickly controlled numerically. First, control the selection device 6 to rotate clockwise by a specified degree to complete the selection, and then rotate counterclockwise to push out the tool.

[0044] As shown in the appendix Figure 2 and Figure 5 and Figure 6As shown, the cleaning device 7 includes a toothed ring 71, side plates 72, a toothed row 73, a diversion box 74, a cleaning strip 75, and a collection box 76. The toothed ring 71 is installed on the outer wall of the clamping cylinder base 43, the side plates 72 are installed on the inner wall of the storage box 1, the toothed row 73 is installed at a position near the bottom on the surface of the side plates 72, the diversion box 74 is installed on the surface of the side plates 72 and at a position above the toothed row 73, and the cleaning strip 75 is installed on the surface of the side plates 72 and at a position above the diversion box 74. The surface of the tool is cleaned by the cleaning strip 75. The toothed ring 71 meshes with the toothed row 73. The toothed row 73 is relatively high. While the toothed ring 71 moves horizontally, it also moves vertically, enabling the toothed ring 71 to maintain its meshing state with the toothed row 73. The collection box 76 is installed on the outer wall of the storage box 1 by means of a thread. When the collection box 76 needs to be cleaned, the collection box 76 can be rotated and removed from above the storage box 1. A chip discharge hole is provided on the surface of the storage box 1 and at a position inside the diversion box 74. The debris inside the diversion box 74 is discharged into the collection box 76 through the chip discharge hole for storage.

[0045] As shown in the Figure 5 accompanying drawings, the clamping groove 46 is divided into upper and lower cavities. The opening at the top of the upper cavity is larger than the opening at the bottom of the lower cavity. The larger opening at the top of the clamping groove 46 facilitates the alignment work, and the smaller opening at the bottom can reduce the error after storage and installation. After the tool is inserted into the smaller lower cavity, it is clamped and fixed through the cooperation of the clamping spring 44 and the clamping block 45 on the outside.

[0046] As shown in the Figure 2 and Figure 3 accompanying drawings, the mounting seat 3 is conical, the inclined sliding groove 31 is inclined, and the bottom of the support seat 41 is provided with an inclined cut surface. The bottom end of the support seat 41 is inserted into the inclined sliding groove 31 through the side slider 42, enabling the support seat 41 to move vertically while moving radially, so that the function of pushing the tool upward can be realized. Four clamping springs 44 and clamping blocks 45 form a group, and the tool is clamped and fixed through the cooperation of the four clamping springs 44 and the clamping blocks 45.

[0047] As shown in the Figure 7As shown, the limit push plate 62 is installed obliquely. The outer end of the extension inclined plate 65 extends to the inside of the support sleeve 69, and the outer end of the limit push plate 62 extends to the outside of the support sleeve 69. When the limit push plate 62 rotates clockwise and contacts the support sleeve 69, the limit push plate 62 will rotate along the position of the mounting pin at the bottom and cross over the support sleeve 69. When the limit push plate 62 rotates counterclockwise, the limit push plate 62 will not deflect under the block of the support column 63, thereby pushing the support sleeve 69 to move inward. The extension inclined plate 65 is relatively short and can directly cross over the outer support sleeve 69 during rotation without hindering the rotation. The extension inclined plate 65 is used to support the support sleeve 69 moving outward to prevent the support sleeve 69 from moving outward too fast and affecting the storage stability.

[0048] As shown in the Figure 5 attachment, one side of the cleaning strip 75 away from the side plate 72 is inclined upward, so that the debris swept by the cleaning strip 75 will move along the surface of the cleaning strip 75 to the position close to the surface of the side plate 72, reducing the number of debris directly falling into the inside of the inclined chute 31. A notch is provided at the position where the cleaning strip 75 is close to the side plate 72. After the debris moves above the cleaning strip 75 to the position close to the side plate 72, it falls downward through the notch into the inside of the diversion box 74, thereby reducing the maintenance frequency. The outer end of the bottom of the diversion box 74 is inclined downward, and the debris falling into the inside of the diversion box 74 will gather and move outward into the inside of the collection box 76 for storage.

[0049] A management method for a machine tool tool management device for a numerically controlled machine tool includes the following steps:

[0050] In the first step, control the power motor 5 to drive the selection device 6 to rotate. Through the selection device 6, the clamping device 4 is toggled to move inward along the inclined chute 31. When the clamping device 4 moves to the innermost position, the tool is clamped into the inside of the clamping groove 46 through the top for storage. According to the same method, multiple tools are respectively installed into different clamping grooves 46.

[0051] In the second step, during the use process, when a tool needs to be selected, control the power motor 5 to rotate clockwise. The power motor 5 drives the rotating disk 61 to rotate clockwise, and the rotating disk 61 drives the limit push plate 62 to rotate clockwise. After the limit push plate 62 contacts the support sleeve 69, it will deflect inward and cross over the support sleeve 69. When the limit push plate 62 crosses over the support sleeve 69 below the tool to be taken out, the selection work is completed.

[0052] In the third step, when the tool needs to be sent out, control the power motor 5 to rotate counterclockwise. At this time, after the limit push plate 62 contacts the support sleeve 69, the limit push plate 62 maintains an inclined state under the support of the support column 63. Apply a force to move inward by pushing the support sleeve 69 through the limit push plate 62. The support sleeve 69 moves inward along the surface of the limit push plate 62 until it is clamped and supported inside the support arc frame 64. During the movement of the support sleeve 69, the insertion rod 66 is driven to move inward. The insertion rod 66 moves inward under the limiting cooperation of the horizontal sliding seat 68 and the horizontal limiting chute 33. When the insertion rod 66 moves inward, it drives the support seat 41 to move inward. When the support seat 41 moves inward under the cooperation and limitation of the side slider 42 and the inclined chute 31, it will also move upward. Thus, the clamping cylinder seat 43 is driven by the support seat 41 to move inward and upward, so as to lift the tool upward through the top opening of the storage box 1;

[0053] In the fourth step, the used tool is inserted into the inside of the clamping groove 46 from the top. When the tool is inserted into the inside of the clamping groove 46, it squeezes the clamping block 45 to move outward and compresses the clamping spring 44. Thus, the tool is clamped and fixed through the cooperation of the clamping spring 44 and the clamping block 45. Then, control the turntable 61 to continue rotating counterclockwise. The turntable 61 drives the support arc frame 64 to rotate so that the support sleeve 69 is separated from the support of the support arc frame 64. After the support sleeve 69 moves to the surface of the extension inclined plate 65, the pulling spring 67 exerts a pulling force on the insertion rod 66 and the support seat 41 to move closer to each other. The support seat 41 will move outward under the limitation of the inclined chute 31. The lower end of the support seat 41 is under the cooperation of the insertion rod 66, the support sleeve 69 and the extension inclined plate 65. The support sleeve 69 slowly moves outward along the surface of the extension inclined plate 65 to improve the operation stability effect, so as to realize the function of recycling and storing the tool;

[0054] In the fifth step, during the process of the support seat 41 moving outward along the inclined chute 31, the support seat 41 drives the toothed ring 71 to move outward through the clamping cylinder seat 43. The toothed ring 71 drives the clamping cylinder seat 43 to rotate self - clockwise under the limitation of the tooth row 73. The clamping cylinder seat 43 drives the tool clamped inside it to rotate self - clockwise. The tool contacts the cleaning strip 75 and rotates self - clockwise. Thus, the surface of the tool is brushed and cleaned by the cleaning strip 75. The tool moves downward while moving outward, making the wiping of the cleaning strip 75 more uniform. At the same time, the debris wiped by the cleaning strip 75 approaches the surface of the side plate 72 under the support of the cleaning strip 75, and then falls into the inside of the diversion box 74. Finally, it slides outward along the inside of the diversion box 74 and falls into the inside of the collection box 76 for storage, thus completing the work of taking out, storing and cleaning the tool.

[0055] Working principle and usage process of the present invention: The device is installed above the workbench through the cooperation of bolts and the mounting chassis 2. When it is necessary to take out the tool, the power motor 5 is controlled to rotate clockwise. The power motor 5 drives the limit push plate 62 to rotate clockwise to the clockwise side below the corresponding tool. Then the power motor 5 rotates counterclockwise. The power motor 5 drives the rotating disk 61 to rotate counterclockwise. The rotating disk 61 drives the limit push plate 62 to rotate counterclockwise. The limit push plate 62 pushes the support sleeve 69 to move inward under the support of the support column 63. The support sleeve 69 moves to the inside of the support arc frame 64 under the push of the limit push plate 62. The power motor 5 stops rotating. While the support sleeve 69 moves inward, it drives the support seat 41 to move inward along the inclined chute 31 through the insertion rod 66. The support seat 41 drives the clamping cylinder seat 43 to move inward and upward at the same time. The clamping cylinder seat 43 drives the tool clamped at its top to push up the fan-shaped top cover plate 8 and extend through the top opening of the storage box 1. Thus, the ejected tool can be clamped and installed for use. After use, the tool is reinserted into the clamping cylinder seat 43. The tool is fixed inside the clamping cylinder seat 43 through the cooperation of the clamping spring 44 and the clamping block 45. Then the power motor 5 continues to rotate counterclockwise. The rotating disk 61 drives the support arc frame 64 and the extension inclined plate 65 to rotate, so that the support sleeve 69 disengages from the support arc frame 64 and moves to the inside of the extension inclined plate 65. At this time, the tension spring 67 exerts a pulling force that makes the insertion rod 66 and the support seat 41 approach each other. The support seat 41 will move outward under the restriction of the inclined chute 31. The lower end of the support seat 41, under the cooperation of the insertion rod 66, the support sleeve 69 and the extension inclined plate 65, the support sleeve 69 slowly moves outward along the surface of the extension inclined plate 65, so that the support seat 41 slowly moves outward along the inclined chute 31. At the same time, the support seat 41 drives the gear ring 71 to move outward through the clamping cylinder seat 43. After the gear ring 71 moves to the inside of the gear row 73, the gear ring 71 drives the clamping cylinder seat 43 to rotate self - clockwise under the restriction of the gear row 73. The clamping cylinder seat 43 drives the tool clamped inside it to rotate self - clockwise. The tool contacts the cleaning strip 75 and rotates self - clockwise. Thus, the surface of the tool is brushed and cleaned by the cleaning strip 75. The tool moves outward and downward at the same time, making the wiping of the cleaning strip 75 more uniform, improving the coverage of wiping. At the same time, the debris wiped by the cleaning strip 75 approaches the surface of the side plate 72 under the support of the cleaning strip 75, and then falls into the diversion box 74 inside, and finally slides outward along the inside of the diversion box 74 and falls into the collection box 76 inside for storage.

When the clamping device (4) moves to the innermost position, the tool is clamped into the inside of the clamping groove (46) through the top for storage. According to the same method, multiple tools are respectively installed in different clamping grooves (46); In the second step, when it is necessary to select a tool during use, the power motor (5) is controlled to rotate clockwise, the power motor (5) drives the rotating disk (61) to rotate clockwise, the rotating disk (61) drives the limit push plate (62) to rotate clockwise, and the limit push plate (62) deflects inward and passes over the support sleeve (69) after contacting the support sleeve (69). When the limit push plate (62) passes over the support sleeve (69) below the tool to be taken out, the selection work is completed; In the third step, when the tool needs to be sent out, the power motor (5) is controlled to rotate counterclockwise. At this time, after the limit push plate (62) contacts the support sleeve (69), the limit push plate (62) remains in an inclined state under the support of the support column (63). The limit push plate (62) pushes the support sleeve (69) to apply a force moving inward, and the support sleeve (69) moves inward along the surface of the limit push plate (62) until it moves to the inner side of the support arc frame (64) and is supported by the clamping. During the movement of the support sleeve (69), the plug-in The rod (66) moves inwardly, and the plug-in rod (66) moves inwardly under the restriction of the transverse slide seat (68) and the transverse limit slide groove (33). When the plug-in rod (66) moves inwardly, it drives the support seat (41) to move inwardly. The support seat (41) also moves upwardly during the process of moving inwardly under the restriction of the side slide block (42) and the inclined slide groove (31), thereby driving the clamping cylinder seat (43) to move inwardly and upwardly through the support seat (41), so that the tool is lifted upward through the top opening of the storage box (1); In the fourth step, the used tool is inserted from the top into the inside of the clamping groove (46). The tool is inserted into the clamping groove (46) to squeeze the clamping block (45) to move outward and compress the clamping spring (44), so that the tool is clamped and fixed by the cooperation of the clamping spring (44) and the clamping block (45). Then, the rotating disk (61) is controlled to continue to rotate counterclockwise, and the rotating disk (61) drives the support arc frame (64) to rotate so that the support sleeve (69) is separated from the support of the support arc frame (64). The support sleeve (69 ) moves to the surface of the extended inclined plate (65), the tension spring (67) applies a pulling force to the plug rod (66) and the support seat (41) to move closer to each other, and the support seat (41) moves outward under the restriction of the inclined slide groove (31). The lower end of the support seat (41) cooperates with the plug rod (66), the support sleeve (69) and the extended inclined plate (65), and the support sleeve (69) moves slowly outward along the surface of the extended inclined plate (65), thereby improving the running stability effect, thereby realizing the function of tool recovery and storage; In the fifth step, when the support seat (41) moves outward along the inclined slide groove (31), the support seat (41) drives the toothed ring (71) to move outward through the clamping cylinder seat (43).
