Description
Technical Field
[0001] This utility model relates to the technical field of nail filing machines, specifically a plug-in nail filing pen. Background Technology
[0002] A nail file is a device used to shape nails. The high-speed rotating file head shapes the nails into a desired form. The file head will wear down after a period of use and needs to be replaced. To avoid injuring the fingers, different files are needed for different areas of the nail.
[0003] Existing grinding heads generally use either rotary or plug-in types, with the plug-in type being the most common. However, existing plug-in types are usually hard-pull and hard-plug designs, where the grinding head is fixed by silicone in the chuck. But there is a drawback: during use, considering that simply fixing the grinding head with silicone can easily cause the grinding head to jump around and scratch nails, so improvements are needed. Utility Model Content
[0004] The purpose of this invention is to provide a plug-in nail polishing pen to solve the problem mentioned in the background art, where the existing plug-in polishing head, which is fixed with silicone, is prone to the problem of the polishing head jumping around and scratching the nails.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a pluggable nail polishing pen, comprising a polishing head housing, a chuck pluggable assembly, a polishing motor body, and a polishing head. The chuck pluggable assembly is inserted from the front end of the polishing head housing and placed inside the polishing head housing. A limiting groove for installing the polishing motor body is provided in the rear end of the polishing head housing. The chuck pluggable assembly includes an inner fixing sleeve, a chuck, a chuck bushing, and an adjusting clamping ring. The rear end of the chuck is inserted into the polishing head housing and connected to the output shaft of the polishing motor body. The other end of the chuck is used to insert into the main shaft of the polishing head. The chuck is covered by a chuck bushing, and the chuck bushing is covered by an inner... The inner fixed sleeve abuts against the inner wall of the grinding head housing. The adjusting pressure ring is inserted into the end of the grinding head housing away from the limiting groove and abuts against one end face of the inner fixed sleeve. The end of the inner fixed sleeve near the adjusting pressure ring is fitted with a foolproof pressure ring. The collet bushing is partially exposed from the inner fixed sleeve and fitted with a bearing whose end face abuts against one end face of the foolproof pressure ring. A limiting step is provided on the inner side of the adjusting pressure ring. The other end of the bearing abuts against the limiting step. The end of the collet inserted into the main shaft of the grinding head is provided with a beveled part that is larger at the front and smaller at the back. After the adjusting pressure ring rotates, the bearing and the foolproof pressure ring press against the beveled part of the collet to clamp the grinding head.
[0006] Preferably, the front end of the inner fixing sleeve is provided with a limiting frustum, the anti-foolproof pressure ring is sleeved outside the limiting frustum, and one end face of the anti-foolproof pressure ring abuts against the stepped surface on the inner fixing sleeve.
[0007] Preferably, in order to achieve the limiting function, the outer side of the chuck bushing is provided with a stepped surface two, and the side of the bearing that abuts against the anti-foolproof pressure ring also abuts against the stepped surface two.
[0008] Preferably, for convenient positioning and rotation, the rear end of the adjusting clamping ring is provided with a positioning pressure ring that is inserted into the front end of the grinding head housing.
[0009] Preferably, for easy reset, a reset spring is abutted between the chuck and the chuck bushing. By adding a reset spring between the chuck and the chuck bushing, the component can be quickly reset when the external force disappears.
[0010] Preferably, to provide an anti-slip function, the grinding head housing is covered with one or more anti-slip grooves. By covering the grinding head housing with anti-slip grooves, the friction can be increased when the hand holds the grinding head housing, thus achieving an anti-slip function.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This structure sets the front end of the chuck in a bevel shape that is smaller at the front and larger at the back. By adjusting the fit between the end faces of the clamping ring, bearing, and anti-fooling clamping ring, during operation, rotating the adjusting clamping ring at the front end drives the spindle to move back and forth. At this time, the spindle moves further back and inserts deeper into the chuck, thus pressing the front end of the beveled surface, thereby clamping the chuck. Rotating the adjusting clamping ring in the opposite direction can release the grinding head. Therefore, this structure can quickly clamp or release the grinding head. Moreover, once clamped, the bearing and anti-fooling clamping ring can firmly clamp the spindle, avoiding the problem of the grinding head jumping and scratching nails due to not being clamped properly.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0021] Example 1
[0022] Please see Figures 1-7This embodiment discloses a pluggable nail polishing pen, including a polishing head housing 1, a polishing motor body 10, a chuck pluggable assembly, and a polishing head 2. The chuck pluggable assembly is inserted from the front end of the polishing head housing 1 and placed inside the polishing head housing 1. A limiting groove 101 for installing the polishing motor body 10 is provided in the rear end of the polishing head housing 1. The chuck pluggable assembly includes an inner fixing sleeve 3, a chuck 4, a chuck bushing 5, and an adjusting clamping ring 6. The rear end of the chuck 4 is inserted into the polishing head housing 1 and connected to the output shaft of the polishing motor body 10. It should be noted that the polishing motor body 10 is prior art and generally includes a motor housing, a motor, a battery, a motor controller, etc. The motor controller, battery, and motor are fixed inside the motor housing, and the motor controller is electrically connected to the motor and battery. One end of the motor is inserted into the limiting groove 101, and the output end of the motor passes through the limiting groove 101. The 01 is connected to the rear end of the chuck 4. The other end of the chuck 4 is used to insert the spindle 201 of the grinding head 2. The chuck 4 is covered with a chuck bushing 5. The chuck bushing 5 is covered with an inner fixing sleeve 3. The outer wall of the inner fixing sleeve 3 abuts against the inner wall of the grinding head housing 1. The adjusting pressure ring 6 is inserted into the end of the grinding head housing 1 away from the limiting groove 101 and abuts against one end face of the inner fixing sleeve 3. The end of the inner fixing sleeve 3 near the adjusting pressure ring 6 is fitted with a foolproof pressure ring. 7. The chuck bushing 5 is partially exposed inside the inner fixing sleeve 3 and is fitted with a bearing 8 whose end face abuts against one end face of the anti-fooling pressure ring 7. The inner side of the adjusting pressure ring 6 is provided with a limiting step 11. The other end of the bearing 8 abuts against the limiting step 11. The end of the chuck 4 that is inserted into the spindle 201 of the grinding head 2 is provided with a beveled part 401 that is larger in the front and smaller in the back. After the adjusting pressure ring 6 rotates, the bearing 8 and the anti-fooling pressure ring 7 press the beveled part 401 of the chuck 4 to clamp the grinding head 2.
[0023] Preferably, the front end of the inner fixing sleeve 3 is provided with a limiting frustum 301, the anti-fooling pressure ring 7 is sleeved outside the limiting frustum 301, and one end face of the anti-fooling pressure ring 7 abuts against the stepped surface 302 on the inner fixing sleeve 3.
[0024] Preferably, in order to achieve the limiting function, the outer side of the chuck bushing 5 is provided with a stepped surface 501, and the side of the bearing 8 that abuts against the anti-foolproof pressure ring 7 also abuts against the stepped surface 501.
[0025] Preferably, for convenient positioning and rotation, the rear end of the adjusting pressure ring 6 is provided with a positioning pressure ring 601 that is inserted into the front end of the grinding head housing 1. This structure, by adding a positioning pressure ring 601, allows the positioning pressure ring 601 to be inserted into the grinding head housing 1, and ensures that the inner wall of the grinding head housing 1 abuts against the outer wall of the positioning pressure ring 601, so that when the adjusting pressure ring 6 is rotated by hand, the positioning pressure ring 601 can play a guiding and limiting role.
[0026] Preferably, for easy reset, a reset spring 9 is abutted between the chuck 4 and the chuck bushing 5. In this embodiment, by adding a reset spring 9 between the chuck 4 and the chuck bushing 5, the component can be quickly reset when the external force disappears.
[0027] Preferably, to provide an anti-slip function, the grinding head housing 1 is covered with one or more anti-slip grooves 102. In this embodiment, by covering the grinding head housing 1 with anti-slip grooves 102, the friction can be increased when the hand holds the grinding head housing 1, thus achieving an anti-slip function.
[0028] Because the adjusting clamping ring 6, bearing 8, and anti-fooling clamping ring 7 abut against each other, and because the end of the chuck 4 that inserts into the main shaft 201 of the grinding head 2 has a beveled part 401 that is larger at the front and smaller at the back, and the beveled part is shaped from small to large at the front, and the chuck 4 itself has a notch for inserting into the main shaft 201, during operation, by rotating the adjusting clamping ring 6 at the front end, the main shaft 201 is driven to move back and forth. At this time, the more the main shaft 201 moves backward, the deeper the main shaft 201 is inserted into the chuck 4, and the front end of the beveled part 401 is pressed, thereby clamping the chuck. When the adjusting clamping ring 6 is rotated in the opposite direction, the grinding head can be released. Therefore, this structure can quickly clamp or release the grinding head, and once clamped, the main shaft 201 can be firmly clamped under the action of the bearing 8 and the anti-fooling clamping ring 7, avoiding the problem of the grinding head jumping and scratching nails due to not being clamped tightly.
[0029] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
