The shell of electronic devices usually adopts a metal back shell structure. The metal back shell has the advantages of wear resistance and easy heat dissipation, and at the same time can make the product leave a high-end impression on users.

[0003] The cutterhead of a gong machine and a drill rig often needs to be replaced. At this time, a cutterhead holder is needed to fix the cutterhead. The cutterhead holder is usually composed of an external clamping ring and an internal clamping claw. The external clamping ring is used to adjust the position and tension of the clamping claw, and the internal clamping claw is used to clamp the tool and prevent it from vibrating and deflecting during processing. When using it, first use the clamping ring to adjust the tension of the cutterhead holder, then insert the cutterhead into the holder and rotate it to the appropriate position, and finally rotate the clamping ring to clamp the tool with the internal clamping claw. When replacing the cutterhead, you need to remove and clean the old cutterhead first, then install the new cutterhead, and perform the above operations. The quality and precision of the cutterhead holder have an important impact on the processing accuracy and production efficiency of the tool, so it needs to be maintained and overhauled regularly. During maintenance, it is necessary to check the wear of the clamping ring and the clamping claw, and clean the dust and impurities inside the clamping claw to ensure its normal operation.

The fast-head-changing pin puller includes a pin pulling rod, which is axially slidably sleeved with a hammer sleeve, the top of the pin pulling rod is fixedly connected to a force-bearing seat, and the hammer sleeve moves upward to form an impact with the force-bearing seat; the bottom end of the pin pulling rod extends into the assembly set, and a detachable component is arranged between the pin pulling rod and the assembly set, and a pin pulling head is passed through the bottom of the assembly set to form a snap-on positioning, and a fitting connection portion is arranged at the bottom of the pin pulling head. The utility model solves the problem of inconvenient positioning and maintenance, improves replacement efficiency, expands the scope of use and flexibility of application, and reduces disassembly costs. The overall structure is compact and stable, the effect is reliable, the operation is simple and fast, it saves time and effort, and it is easy to promote and use.

[0005] The above patent simply solves the problem of adapting the pin-pulling connecting rod to various structures, but makes the overall structure complicated, and cannot conveniently and quickly remove the damaged cutter disc holder from the cutter disc fixing hole to efficiently replace the new holder, and the overall structure is complicated to operate.

[0006] In summary, the utility model provides a tool for quickly disassembling the cutter head holder of a gong machine and a drilling rig to solve the above-mentioned problems. Utility Model Content

[0007] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a tool for quickly disassembling the cutter disc holder of a gong machine and a drill rig. The utility model has the advantages that the connecting sleeve is pressed against the conical outer claws at the bottom of the holder, and the conical outer claws will shrink inward, with a simple structure. Then the base is pushed and fixed with the palm of the hand, which is easy to operate. The contraction of the spring drives the push rod to move downward, thereby supporting the conical outer claws, with great flexibility, until the holder is pushed out of the cutter disc, and then the holder can be replaced, saving time and effort in the process of replacing the holder.

[0008] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0009] A tool for quickly disassembling a cutter disc holder of a gong machine drill, comprising: a cutter disc base and a connecting sleeve, wherein the connecting sleeve is a hollow structure, a conical outer claw is installed on the bottom side of the connecting sleeve, a push rod is installed on the upper part of the conical outer claw, the top of the push rod passes through the connecting sleeve, and a positioning pin is installed at the bottom of the push rod, a fixed base is installed on the top of the push rod, and a spring is installed at the bottom of the fixed base, and the diameter of the spring is greater than the diameter of the connecting sleeve.

[0010] By adopting the above technical solution, the locating pin at the bottom of the push rod is inserted into the middle of the conical outer claw at the bottom of the card seat that needs to be removed, and then the connecting sleeve is pressed against the conical outer claw at the bottom of the card seat. At this time, the conical outer claw will shrink inward. When the conical outer claws fit each other, the fixed base is pushed. The downward movement of the fixed base will drive the contraction of the spring and then drive the push rod downward evenly until the card seat is pushed out of the cutter disc. The operation is simple and convenient, and the diameter of the push rod is slightly smaller than the diameter of the connecting sleeve, so the push rod can slide more stably inside the connecting sleeve. The fixed base has a disc structure with a smooth surface, so it is more convenient to push the fixed base and the overall appearance is more beautiful. The diameter of the spring is larger than the diameter of the connecting sleeve, so the spring will not be affected by the connecting sleeve when it is compressed or extended. When the replacement is completed, the fixed base is released and the spring returns to its original state, that is, the device can be driven to detach from the cutter disc base without the action of external force.

[0011] The utility model is further configured as follows: a cylinder is fixed to the middle of the circumference of the connecting sleeve, the diameter of the cylinder is greater than or equal to the diameter of the fixed base, and the upper part of the cylinder is connected to the bottom of the spring.

[0012] By adopting the above technical solution, the design of the cylinder increases the contact area between the spring and the connecting sleeve, and the compression of the spring can drive the connecting sleeve and the push rod to move downward. When the spring returns to its original state without the need for external force, it can drive the connecting sleeve and the push rod to return to their original positions. That is, the connection between the spring and the cylinder can improve the flexibility of the device and can improve the efficiency of replacing the card seat of the device.

[0013] The utility model is further configured as follows: a positioning hole is opened at the center of the top of the push rod.

[0014] By adopting the above technical solution, the design of the positioning hole facilitates the fixation of the ejector rod and the fixed base, that is, the fixed base and the ejector rod become a whole.

[0015] The utility model is further configured as follows: a threaded hole is penetrated through the middle of the fixed base.

[0016] By adopting the above technical solution, the diameter of the threaded hole is equal to the diameter of the positioning hole, and thus only one part is needed to connect the ejector rod and the fixed base into a whole.

[0017] The utility model is further configured as follows: the positioning hole and the notch of the threaded hole are threadedly connected with an M screw.

[0018] By adopting the above technical solution, the diameter of the M screw is consistent with the diameter of the positioning hole and the threaded hole, that is, the M screw is compatible with the positioning hole and the threaded hole, and then the M screw can threadably connect the push rod and the fixed base, and when the fixed base and the push rod are working, there will be no shaking, thereby improving the stability of the card holder replacement process.

[0019] The utility model is further configured as follows: the conical outer claws are fixed on a cutter disc base, and a plurality of sets of cutter disc holder fixing holes are fixed on the upper part of the cutter disc base.

[0020] By adopting the above technical solution, the cutter disc base is an integral body, and the cutter disc holder fixing holes are neatly arranged. When the holder in the cutter disc is damaged, the damaged holder can be replaced through the cutter disc holder fixing holes.

[0021] The utility model is further configured as follows: a connecting rod is fixed inside the fixing hole of the cutter disc holder, and the upper part of the connecting rod is slidably matched with the conical outer claw.

[0022] By adopting the above technical solution, the design of the connecting rod can improve the support platform for the tapered outer claws, thereby making the process of the tapered outer claws contracting inwards or moving downwards more stable.

[0023] In summary, the beneficial technical effects of the utility model are:

[0024] 1. Press the connecting sleeve against the conical outer claws at the bottom of the holder, and the conical outer claws will shrink inward. The structure is simple. Then push the fixed base with the palm of your hand. The operation is convenient. The contraction of the spring drives the push rod to move downward, thereby supporting the conical outer claws. It has great flexibility until the holder is pushed out of the cutter disc, and then the holder can be replaced. In the process of replacing the holder, time and effort are saved.

[0025] 2. The diameter of the M3 screw is consistent with the diameter of the positioning hole and the threaded hole, that is, the M3 screw is compatible with the positioning hole and the threaded hole, and then the M3 can threadedly connect the ejector rod and the fixed base, and when the fixed base and the ejector rod are working, there will be no shaking, which improves the stability of the card holder replacement process.
