[0001] This utility model relates to the field of polishing pen technology, specifically a detachable polishing pen. Background Technology

[0002] A polishing pen is a precision handheld polishing tool widely used in metal processing, mold making, engraving art, precision instrument adjustment and other fields. A polishing pen usually consists of a handle and a replaceable polishing head. The handle is easy for the operator to hold, while the polishing head is responsible for performing the specific polishing work. As a flexible and versatile tool, the polishing pen greatly improves work efficiency and reduces labor intensity, playing an important role in manufacturing and other fields.

[0003] However, existing polishing pens often require an external power cord or rely on their own batteries for power. This method is inflexible, and the small battery capacity of the polishing pen itself leads to low battery life, which reduces the convenience of using the polishing pen. Therefore, we propose a detachable polishing pen to solve the above-mentioned problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a detachable polishing pen, which solves the problem that often requires an external power cord or its own battery for power supply. However, this method is inflexible, and the small battery capacity of the polishing pen itself leads to low battery life, thus reducing the convenience of using the polishing pen.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a detachable polishing pen, including a body, a connecting nut rotatably connected to the bottom end of the body, and a front handle rotatably connected to the bottom end of the connecting nut, a motor disposed in the inner cavity of the body, a main shaft connected to the output end of the motor, a silicone tube disposed in the inner cavity of the bottom end of the main shaft, and a polishing needle disposed in the inner cavity of the silicone tube;

[0006] The top of the device is rotatably connected to a pen clip connecting sleeve, the top of the pen clip connecting sleeve is rotatably connected to a housing, the inner cavity of the housing is provided with a plastic bracket, and the inner cavity of the plastic bracket is provided with a battery, the bottom end of the plastic bracket is provided with a DC head, and the pen clip connecting sleeve is provided with a DC connector for inserting the DC head.

[0007] Preferably, the bottom end of the spindle is rotatably connected to a spindle cover, and the grinding needle penetrates the inner cavity of the spindle cover.

[0013] Beneficial effects

[0014] This invention provides a detachable polishing pen. Compared with the prior art, it has the following advantages:

[0015] This detachable polishing pen, through its body, allows for the installation of the front handle via a connecting nut, as well as the motor. It also allows for the installation of a DC connector via a pen clip connecting sleeve. Since the motor's output end is connected to a spindle, and the spindle's bottom cavity contains a silicone tube with a polishing needle inside, the polishing needle can be stably installed within the spindle's cavity via the silicone tube. The motor's operation then drives the polishing needle via the spindle, enabling polishing of external objects. A plastic bracket stably mounts the battery in the housing, providing protection for the battery and also allowing for the installation of the DC connector.

[0016] Because the bottom of the DC head is plugged into the DC connector and the bottom of the housing is rotatably connected to the pen clip connector, the DC connector and the DC head can be connected by rotating the housing and the pen clip connector. This allows the battery to power the motor, enabling the polishing pen to polish external objects. When the battery is dead, the housing and pen clip connector can be disassembled to separate the DC connector and the DC head. Then, by replacing the housing with another battery, the motor can be powered again. This improves the convenience of the device. The whole process is simple and convenient to operate and does not affect the user's use of the polishing pen. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a technical solution: a detachable polishing pen, including a body 1, a connecting nut 2 rotatably connected to the bottom end of the body 1, and a front handle 3 rotatably connected to the bottom end of the connecting nut 2, a motor 4 disposed in the inner cavity of the body 1, a main shaft 5 connected to the output end of the motor 4, a silicone tube 6 disposed in the inner cavity of the bottom end of the main shaft 5, and a polishing needle 7 disposed in the inner cavity of the silicone tube 6; a pen clip connecting sleeve 11 rotatably connected to the top end of the body 1, a housing 12 rotatably connected to the top end of the pen clip connecting sleeve 11, a plastic bracket 13 disposed in the inner cavity of the housing 12, a battery 14 disposed in the inner cavity of the plastic bracket 13, a DC head 15 disposed at the bottom end of the plastic bracket 13, and a DC connector 16 for inserting the DC head 15 disposed on the pen clip connecting sleeve 11;

[0024] The body 1 allows for the installation of both the front handle 3 and the motor 4 via the connecting nut 2. It also allows for the installation of the DC connector 16 via the pen clip connecting sleeve 11. Since the output end of the motor 4 is connected to the spindle 5, and the bottom cavity of the spindle 5 contains a silicone tube 6 with a grinding needle 7, the grinding needle 7 can be stably installed within the spindle 5 via the silicone tube 6. The operation of the motor 4 drives the grinding needle 7 via the spindle 5, thus enabling the grinding of external objects. The plastic bracket 13 stably mounts the battery 14 onto the housing 12, providing protection for the battery 14, and also allows for the installation of the DC connector 15. The bottom end of the DC connector 15 is connected to... The DC connector 16 is plugged in and connected, and the bottom end of the housing 12 is rotatably connected to the pen clip connecting sleeve 11. Therefore, by rotatably connecting the housing 12 and the pen clip connecting sleeve 11, the DC connector 16 and the DC head 15 can be connected, thereby enabling the battery 14 to power the motor 4 so that the polishing needle 7 can polish the external object. When the battery 14 is out of power, the housing 12 and the pen clip connecting sleeve 11 can be disassembled and separated, thereby allowing the DC connector 16 and the DC head 15 to be unplugged and plugged away. Then, by replacing the housing 12 with another battery 14, power can be supplied to the motor 4, thereby improving the convenience of the device. The whole process is simple and convenient to operate and does not affect the user's use of the polishing pen.

[0025] See Figure 2 , Figure 3 The bottom end of the spindle 5 is rotatably connected to the spindle cover 8, and the grinding needle 7 penetrates the inner cavity of the spindle cover 8.

[0026] The spindle cover 8 can be installed at the bottom of the spindle 5 and can also limit the grinding needle 7 installed on the spindle cover 8, thereby improving the stability of the grinding needle 7.

[0027] See Figure 2 , Figure 3 A rubber ring 9 is provided in the middle of the inner cavity of the front handle 3, and a bearing 10 for sleeved on the outside of the main shaft 5 is provided in the inner cavity of the rubber ring 9.

[0028] The stability of the spindle 5 rotation can be improved by the cooperation of the rubber ring 9 and the bearing 10.

[0029] See Figure 2 - Figure 4 The top of the DC connector 15 is connected to the battery 14, and the bottom of the DC connector 16 is connected to the motor 4, which allows the battery 14 to supply power to the motor 4 through the DC connector 15 and the DC connector 16.

[0030] See Figure 2 - Figure 4A control switch 17 is provided on the outer wall surface of the housing 12, which allows the user to easily turn on the battery 14 to supply power to the motor 4.

[0032] See Figure 2 , Figure 3 The top of the plastic bracket 13 is provided with a charging port, which is electrically connected to the battery 14. An external power source can be connected through the charging port to charge the battery 14.

[0033] During operation, the front handle 3 can be installed via the connecting nut 2, and the motor 4 can be installed and fixed. Simultaneously, the DC connector 16 can be installed via the pen clip connecting sleeve 11. Since the output end of the motor 4 is connected to the spindle 5, and a silicone tube 6 is installed in the inner cavity of the bottom end of the spindle 5, with a grinding needle 7 inside the silicone tube 6, the grinding needle 7 can be stably installed inside the spindle 5 via the silicone tube 6. Then, the operation of the motor 4 drives the grinding needle 7 via the spindle 5, thereby performing grinding on external objects. The plastic bracket 13 stably installs the battery 14 on the housing 12, providing protection for the battery 14, and also allows for the installation of the DC head 15. Because the bottom of the DC head 15... The end of the housing 12 is plugged into the DC connector 16, and the bottom end of the housing 12 is rotatably connected to the pen clip connecting sleeve 11. Therefore, by rotatably connecting the housing 12 and the pen clip connecting sleeve 11, the DC connector 16 and the DC head 15 can be connected, thereby enabling the battery 14 to supply power to the motor 4 so that the polishing needle 7 can polish the external object. When the battery 14 is out of power, the housing 12 and the pen clip connecting sleeve 11 can be disassembled and separated, thereby allowing the DC connector 16 and the DC head 15 to be unplugged and plugged away. Then, by replacing the housing 12 with another battery 14, power can be supplied to the motor 4, thereby improving the convenience of the device. The whole process is simple and convenient to operate and does not affect the user's use of the polishing pen.

[0034] The spindle cover 8 can be installed at the bottom of the spindle 5 and can also limit the grinding needle 7 installed on the spindle cover 8, thereby improving the stability of the grinding needle 7. The cooperation of the rubber ring 9 and the bearing 10 can improve the rotational stability of the spindle 5. Since the outer wall surface of the housing 12 is provided with a control switch 17, the user can easily turn on the battery 14 to supply power to the motor 4. Through the charging port, an external power source can be connected to charge the battery 14.

[0035] In summary, this device can separate the polishing pen, thus enabling battery replacement. The entire process is simple and convenient, and does not affect the user's use of the polishing pen.

[0036] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
