[0005] According to some embodiments of the present invention, when the connector is inserted into the mounting cavity, the first snap-fit member is located outside the fixed base, and the driving device can drive the second snap-fit member to move, so that the second snap-fit member can move closer to or further away from the first snap-fit member, thereby fixing the first snap-fit member between the second snap-fit member and the fixed base or making the first snap-fit member removable from between the second snap-fit member and the fixed base.
[0006] According to some embodiments of the present invention, the first snap-fit member includes a first vertical section and a second vertical section disposed at the bottom of the first vertical section, wherein the diameter of the second vertical section is larger than the diameter of the first vertical section;
[0007] When the driving device drives the second latching member to approach the first latching member, the second latching member is located above the second vertical segment. The second latching member fixes the first vertical segment between the second latching member and the fixing base, and the second latching member prevents the second vertical segment from moving upward.
[0008] According to some embodiments of the present invention, two second snap-fit members are provided, and the two second snap-fit members are respectively located on the left and right sides of the fixing base;
[0009] The connector can be rotatably inserted into the mounting cavity, and two first snap-fit members are provided, with the two first snap-fit members located on the left and right side walls of the fixing seat respectively.
[0010] The joint is rotatable between a first position and a second position;
[0011] In the first position, one of the first latching members is located between one of the second latching members and the fixed base, and the driving device drives the two second latching members to move, and one of the second latching members fixes one of the first latching members between one of the second latching members and the fixed base;
[0012] In the second position, another first latching member is located between another second latching member and the fixing base, and the driving device drives the two second latching members to move, with the other second latching member fixing the other first latching member between the other second latching member and the fixing base.
[0013] According to some embodiments of the present invention, the fixing base has a blocking member for positioning the first position or the second position.
[0014] According to some embodiments of the present invention, the front side of the fixed base has a limiting seat, and the blocking member is placed horizontally and can be moved back and forth on the limiting seat;
[0015] When the connector is in the second position, the limiting seat is located on the front side of the drill bag, and the blocking member can prevent the drill bag from rotating towards the blocking member.
[0016] According to some embodiments of the present invention, the middle portions of the two second snap-fit members are rotatably mounted on the fixed base, the driving device is connected to one end of the two second snap-fit members, and the driving device can drive the two second snap-fit members to rotate, so that the other ends of the two second snap-fit members approach or move away from the outer wall of the fixed base.
[0017] According to some embodiments of the present invention, the driving device is a cylinder; the two first snap-fit members are arranged at 180° relative to the center of the connector.
[0018] According to some embodiments of the present invention, the other end of the second snap-fit member has a recess that matches the shape of the first snap-fit member.
[0019] According to some embodiments of the present invention, a linkage component is also included, wherein the connector has a communicating cavity, and the linkage component is located within the communicating cavity;
[0020] The drilling motor has a rotating shaft, and the drill bag also includes a linkage shaft located above the rotating shaft. The upper and lower ends of the linkage are respectively engaged with the linkage shaft and the rotating shaft, and the linkage shaft can drive multiple drill bits to rotate.
[0021] The drill bag quick-change device according to the embodiments of this utility model has at least the following technical effects:
[0022] 1. The top of the drilling motor is equipped with a fixed base. The fixed base has an installation cavity and a clamping structure. When installing the drill bag, simply insert the connector at the bottom of the drill bag into the installation cavity. Then, the drive device of the clamping structure drives the second snap-fit component to snap into the first snap-fit component of the drill bag, thus fixing the drill bag on the fixed base. This achieves quick installation of the drill bag. When disassembling, simply drive the second snap-fit component to disengage from the first snap-fit component, and the drill bag can be removed from the fixed base. This achieves quick disassembly of the drill bag. No additional tools (such as wrenches) are required for installation or disassembly, making the installation and disassembly of the drill bag more convenient.
[0023] 2. Since the connector can be rotatably inserted into the installation cavity, the angle of the drill bag can be adjusted; and since there are two first and two second locking parts, the second locking part will engage with the first locking part 330 whenever the drill bag is rotated to the first or second position, that is, the drill bag is fixed in the installation cavity when it is rotated to the first or second position.

[0041] Reference Figure 1 , 2 As shown in Figure 3, the quick-change drill bag device according to an embodiment of the present invention includes a drilling motor 100, a fixing base 200, a drill bag 300, and a clamping structure 400. The fixing base 200 is located on top of the drilling motor 100 and has a mounting cavity 210 inside. The drill bag 300 is provided with multiple drill bits 310, and the bottom of the drill bag 300 has a connector 320 and a first snap-fit member 330. The connector 320 is detachably inserted into the mounting cavity 210, and the drilling motor 100 can drive the multiple drill bits 310 to rotate. The clamping structure 400 includes a driving device 410 and a second snap-fit member 420, as shown in Figure 3. Figure 2 , 4 As shown, the second snap-fit member 420 is movably disposed on the fixed base 200, and the driving device 410 is mounted on the fixed base 200. The driving device 410 can drive the second snap-fit member 420 to snap-fit with the first snap-fit member 330, so that the connector 320 is fixed in the mounting cavity 210, or the driving device 410 can drive the second snap-fit member 420 to disengage from the first snap-fit member 330, so that the connector 320 can be removed from the mounting cavity 210.
[0042] The top of the drilling motor 100 is provided with a fixing base 200. The fixing base 200 has a mounting cavity 210 and a clamping structure 400. When installing the drill bag 300, simply insert the connector 320 at the bottom of the drill bag 300 into the mounting cavity 210, and then the driving device 410 of the clamping structure 400 drives the second snap-fit 420 to snap into the first snap-fit 330 of the drill bag 300, so that the drill bag 300 is fixed on the fixing base 200, realizing the quick installation of the drill bag 300. When disassembling, simply drive the second snap-fit 420 to disengage from the first snap-fit 330, and the drill bag 300 can be taken out from the fixing base 200, realizing the quick disassembly of the drill bag 300. No additional tools (such as wrenches) are required for installation or disassembly, making the installation and disassembly of the drill bag 300 more convenient.
[0043] Understandably, after the connector 320 at the bottom of the drill bag 300 is inserted into the mounting cavity 210, the drilling motor 100 can drive multiple drill bits 310 to rotate.
[0044] It is understandable that the second snap-fit 420 is movably disposed on the fixed base 200, meaning that the second snap-fit 420 is movable and / or rotatably disposed on the fixed base 200.
[0045] In some embodiments of this utility model, such as Figure 4 As shown, when the connector 320 is inserted into the mounting cavity 210, the first snap-fit member 330 is located outside the fixing base 200. The driving device 410 can drive the second snap-fit member 420 to move, so that the second snap-fit member 420 can move closer to or further away from the first snap-fit member 330, thereby fixing the first snap-fit member 330 between the second snap-fit member 420 and the fixing base 200 or allowing the first snap-fit member 330 to be removed from between the second snap-fit member 420 and the fixing base 200.
[0046] With the above structure, the first snap-fit member 330 of the drill bag 300 is located outside the fixed base 200, while the connector 320 of the drill bag 300 is installed inside the fixed base 200, which facilitates the snap-fit of the second snap-fit member 420 with the first snap-fit member 330, making the assembly and disassembly of the drill bag 300 more convenient.
[0047] During installation, the connector 320 of the drill bag 300 is installed in the mounting cavity 210 of the fixed base 200. The first snap-fit member 330 is located outside the outer wall of the fixed base 200 and between the second snap-fit member 420 and the outer wall of the fixed base 200. The driving device 410 drives the second snap-fit member 420 to move, so that the second snap-fit member 420 approaches the first snap-fit member 330, thereby fixing the first snap-fit member 330 between the second snap-fit member 420 and the fixed base 200, restricting the up and down movement of the drill bag 300, thereby fixing the drill bag 300 in the mounting cavity 210.
[0048] During disassembly, the drive device 410 drives the second snap-fit member 420 to move away from the first snap-fit member 330, so that the second snap-fit member 420 no longer fixes the first snap-fit member 330 between the second snap-fit member 420 and the fixing seat 200, thereby allowing the drill bag 300 to move up and down, so that the connector 320 can be removed from the mounting cavity 210.
[0049] It is understandable that the second card connector 420 being able to be near or far from the first card connector 330 refers to its working position.
[0050] When the second snap-fit 420 is in the close position, the second snap-fit 420 snaps into the first snap-fit 330, fixing the first snap-fit 330 between the second snap-fit 420 and the fixing base 200, restricting the drill bag 300 from moving up and down, and fixing the drill bag 300 inside the mounting cavity 210.
[0051] When the second locking member 420 is in the away position, the second locking member 420 and the first locking member 330 disengage, the drill bag 300 can move up and down, and the connector 320 can be removed from the mounting cavity 210. In a further embodiment of this utility model, such as Figure 4 As shown, the first snap-fit component 330 includes a first vertical section 331 and a second vertical section 332 disposed at the bottom of the first vertical section 331, wherein the diameter of the second vertical section 332 is larger than the diameter of the first vertical section 331;
[0052] When the driving device 410 drives the second latching member 420 to approach the first latching member 330, the second latching member 420 is located above the second vertical section 332. The second latching member 420 fixes the first vertical section 331 between the second latching member 420 and the fixing base 200, and the second latching member 420 prevents the second vertical section 332 from moving upward.
[0053] The first locking member 330 adopts the above structure, making the first locking member 330 bolt-shaped. When the second locking member 420 moves to directly above the second vertical section 332 or moves to fix the first vertical section 331 between the second locking member 420 and the fixing seat 200, the second locking member 420 can prevent the first locking member 330 from moving upward. Since the drill bag 300 is connected to the first locking member 330, it also prevents the drill bag 300 from moving upward, thereby fixing the joint 320 of the drill bag 300 in the mounting cavity 210.
[0054] When the second locking member 420 moves away from directly above the second vertical section 332 (the second locking member 420 moves away from the first locking member 330), the second locking member 420 no longer blocks the second vertical section 332 from moving upward, and the drill bag 300 can move upward, so that the connector 320 can be taken out from the mounting cavity 210.
[0055] In a further embodiment of this utility model, such as Figure 5 As shown, there are two second card connectors 420, which are located on the left and right sides of the fixing base 200 respectively.
[0056] The connector 320 is rotatably inserted into the mounting cavity 210. Two first snap-fit pieces 330 are provided, and the two first snap-fit pieces 330 are located on the left and right side walls of the fixing base 200 respectively.
[0057] Connector 320 is rotatable between a first position and a second position;
[0058] like Figure 5 , 6 As shown, in the first position, one of the first card contacts 330 (α1) is located between one of the second card contacts 420 (β1) and the fixing base 200. The driving device 410 drives the two second card contacts 420 to move, and one of the second card contacts 420 (β1) fixes one of the first card contacts 330 (α1) between one of the second card contacts 420 (β1) and the fixing base 200.
[0059] like Figure 7 , 8 As shown, in the second position, another first latching member 330 (α2) is located between another second latching member 420 (β2) and the fixing base 200. The driving device 410 drives the two second latching members 420 to move, and the other second latching member 420 (β2) fixes the other first latching member 330 (α2) between the other second latching member 420 (β2) and the fixing base 200.
[0060] Since the connector 320 can be rotatably inserted into the mounting cavity 210, the angle of the drill bag 300 can be adjusted; and since there are two of the first snap-fit member 330 and the second snap-fit member 420, the second snap-fit member 420 will engage with the first snap-fit member 330 whenever the drill bag 300 is rotated to the first position or the second position, that is, the drill bag 300 is fixed in the mounting cavity 210 when it is rotated to the first position or the second position.
[0061] Specifically, such as Figure 5 , 6 As shown, when the connector 320 is in the first position, from the top view, the drill bag 300 extends laterally, and the multiple drill bits 310 on the drill bag 300 are arranged in the front-back direction. The second snap-fit member 420 located to the right of the fixed seat 200 snaps into one of the first snap-fit members 330 (α1), and the other first snap-fit member 330 (α2) is not located between the second snap-fit member 420 and the fixed seat 200 to the left of the fixed seat 200.
[0062] like Figure 7 , 8 As shown, when the connector 320 is in the second position, the drill bag 300 extends vertically when viewed from above. Multiple drill bits 310 on the drill bag 300 are arranged in the left-right direction. The second locking member 420 located to the left of the fixed seat 200 is locked with another first locking member 330 (α2). One of the first locking members 330 (α1) is not located between the second locking member 420 and the fixed seat 200 to the right of the fixed seat 200.
[0063] The first position can be that the drill bag 300 is at 0°, and the second position can be that the drill bag 300 is at 90°.
[0064] It is conceivable that, while ensuring that the second connector 420 can engage with the first connector 330, the second position can also be 45°, 60°, 75° or other angles.
[0065] Specifically, such as Figure 5 As shown, the two first snap-fit pieces 330 are positioned at 180° relative to the center of the connector 320, and the second position is 45°.
[0066] It is understandable that, such as Figure 6 As shown, the fact that one of the first latching members 330 (α1) is located between one of the second latching members 420 (β1) and the fixing base 200 means that one of the first latching members 330 (α1) is located within the movement trajectory of one of the second latching members 420 (β1), so that when one of the second latching members 420 (β1) moves to the close position, one of the second latching members 420 (β1) fixes one of the first latching members 330 (α1) between one of the second latching members 420 (β1) and the fixing base 200;
[0067] Similarly, the other first card connector 330 (α2) is also located within the movement trajectory of the other second card connector 420 (β2), thereby ensuring that the other second card connector 420 (β2) fixes the other first card connector 330 (α2) between the other second card connector 420 (β2) and the fixing base 200.
[0068] In a further embodiment of this utility model, such as Figure 7 As shown, the mounting base 200 has a blocking element 220 for positioning a first position or a second position.
[0069] By incorporating a blocking element 220, the drill bag 300 can be precisely rotated to the first or second position.
[0070] In a further embodiment of this utility model, such as Figure 7 , 9 As shown, the front side of the fixed base 200 has a limiting base 230, and the blocking member 220 is placed horizontally and can be moved back and forth on the limiting base 230;
[0071] like Figure 7 As shown, when the connector 320 is in the second position, the limiting seat 230 is located on the front side of the drill bag 300, and the blocking member 220 can prevent the drill bag 300 from rotating in the direction close to the blocking member 220 (counterclockwise).
[0072] By setting the limit seat 230, the position of the blocking member 220 in the front and rear directions can be adjusted, thereby adjusting the positioning position.
[0073] In a further embodiment of this utility model, such as Figure 10 As shown, the middle parts of the two second snap-fit pieces 420 are rotatably mounted on the fixed base 200. The drive device 410 is connected to one end (rear end) of the two second snap-fit pieces 420. The drive device 410 can drive the two second snap-fit pieces 420 to rotate, so that the other ends (front ends) of the two second snap-fit pieces 420 move closer to each other or further away from each other, so that the other ends of the two second snap-fit pieces 420 move closer to or further away from the outer wall of the fixed base 200.
[0074] With the above structure, the rotation of the second latching member 420 controls whether the second latching member 420 is latched with the first latching member 330.
[0075] For example, such as Figure 6 , 10 As shown, when the connector 320 is in the first position, the drive device 410 drives the two second snap-fit pieces 420 to rotate, so that the other end of the second snap-fit piece 420 located on the right side of the fixed post fixes one of the first snap-fit pieces 330 (α1) between the other end of the second snap-fit piece 420 and the fixed base 200.
[0076] In a further embodiment of this utility model, the driving device 410 is a cylinder, which facilitates driving the two second snap-fit parts 420 to rotate.
[0077] In a further embodiment of this utility model, such as Figure 4 As shown, the other end of the second snap-fit 420 has a recess 421 that matches the shape of the first snap-fit 330. The recess 421 cooperates with the first snap-fit 330 to better restrict the rotation of the drill bag 300.
[0078] In some embodiments of this utility model, such as Figure 1 , 3 As shown, it also includes a linkage 500, and the connector 320 has a communicating cavity 321, with the linkage 500 located inside the communicating cavity 321;
[0079] The drilling motor 100 has a rotating shaft 101, and the drill bag 300 is provided with a linkage shaft 340 located above the rotating shaft 101. The upper and lower ends of the linkage member 500 are respectively connected to the linkage shaft 340 and the rotating shaft 101. The linkage shaft 340 can drive multiple drill bits 310 to rotate.
[0080] The drilling bag 300 is equipped with a linkage component 500 and a drilling bag 300 including a linkage shaft 340, which facilitates the installation and removal of the drilling bag 300.
[0081] like Figure 3As shown, during installation, the linkage 500 is pre-installed on the rotating shaft 101 of the drilling motor 100 and located in the mounting cavity 210. Then, the connector 320 at the bottom of the drill bag 300 is inserted into the mounting cavity 210. At the same time, the linkage shaft 340 of the drill bag 300 is inserted into the upper end of the linkage 500, so that the upper and lower ends of the linkage 500 are respectively engaged with the linkage shaft 340 and the rotating shaft 101. When working, the rotating shaft 101 of the motor rotates, and the rotating shaft 101 drives the linkage shaft 340 to rotate through the linkage 500. The linkage shaft 340 then drives multiple drill bits 310 to rotate.
[0082] Specifically, the linkage shaft 340 is linked to one of the drill bits 310 via gears, and two adjacent drill bits 310 are also linked via gears. During operation, the linkage shaft 340 drives one of the drill bits 310 to rotate, and one of the drill bits 310 then drives the other drill bits 310 to rotate via gears. It is conceivable that other structures can also be used to link two adjacent drill bits 310.
[0083] While ensuring that the linkage shaft 340 can drive multiple drill bits 310 to rotate, other transmission methods can also be used between the linkage shaft 340 and the drill bits 310.
