Description

Technical Field

[0001] The utility model relates to the technical field of electric grinders, in particular to a clamping device of an electric grinder. Background Art

[0002] The full name of electric grinder is reciprocating electric polishing grinder (also known as filing grinder), which is widely used in finishing and surface polishing in the mold industry;

[0003] In the prior art, electric grinders are mainly used to polish the surface of objects. Therefore, in addition to electric grinders for grinding objects, in the nail industry, electric grinders for grinding nails also belong to electric grinders. The grinding heads of electric grinders in the nail industry are divided into many types. When performing nail grinding, the grinding head often needs to be replaced. The frequent replacement of the grinding head can easily cause an unstable connection between the grinding head and the electric grinder body, causing the grinding head to shake, resulting in deviations in the grinding of the nails and damage to the nails. Therefore, we propose a clamping device for an electric grinder. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art. The electric grinder is mainly used to polish the surface of an object. Therefore, in addition to the electric grinder for grinding objects, in the nail industry, the electric grinder for grinding nails also belongs to the electric grinder. The grinding heads of the electric grinders in the nail industry are divided into many types. When performing nail grinding, the grinding head often needs to be replaced. The frequent replacement of the grinding head can easily cause an unstable connection between the grinding head and the electric grinder body, thereby causing the grinding head to shake, resulting in deviations in the grinding of the nails and damage to the nails.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A clamping device for an electric grinder comprises a grinder body, a control switch capable of turning on the grinder body is arranged near the bottom of the outer periphery of the grinder body, and symmetrically arranged protrusions for users to hold are arranged near the top of the outer periphery of the grinder body, a connecting roller is arranged at the top of the grinder body, and a grinding head capable of grinding nails is arranged at the top of the connecting roller;

[0007] Three electric push rods are also equidistantly arranged inside the protrusion, and an arc-shaped clamping plate is arranged at the output end of the electric push rod corresponding to the outer diameter of the connecting roller, and a sliding plate that reduces the friction between the connecting roller and the arc-shaped clamping plate is arranged on the side of the arc-shaped clamping plate close to the connecting roller. Through the setting of the electric push rod, the arc-shaped clamping plate can be effectively pushed, and the driving force of the electric push rod can effectively enable the arc-shaped clamping plate to clamp the connecting roller to limit the connecting roller, and the sliding plate can effectively enable the connecting roller and the sliding plate to slide, so that the connecting roller can be rotated by the driving motor, thereby driving the grinding head to grind the nails.

[0008] As a preferred solution of the utility model, a connecting groove for connection is provided on the periphery of the connecting roller, away from one end of the grinding head and located on the top of the grinder body, and an arc groove for fixed connection is provided on the periphery of the connecting roller near the bottom.

[0009] As a preferred solution of the utility model, a driving motor capable of driving the connecting roller to rotate is arranged inside the grinder body, and a fixed roller connected to the arc groove is symmetrically fixed at the output end of the driving motor. The fixed roller slides to the closed part of the arc groove and is clamped together with the arc groove.

[0010] As a preferred solution of the utility model, a circuit board capable of controlling the opening and closing of the drive motor is arranged inside the grinder body and at the bottom of the drive motor, and a battery capable of powering the drive motor is arranged at the bottom of the circuit board, and the circuit board is electrically connected to the control switch.

[0011] As a preferred solution of the utility model, the surface of the control switch is provided with a first anti-slip protrusion for facilitating sliding of the user, and the side surface of the protrusion away from the grinder body is provided with a second anti-slip protrusion to prevent sliding when the user holds it.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] In the utility model, through the setting of the electric push rod, the electric push rod pushes the arc-shaped clamping plate, so that the arc-shaped clamping plate that matches the outer diameter of the connecting roller can be more stably fitted on the connecting roller, and the connecting roller is limited, so as to clamp the connecting roller, and prevent the connecting roller from being unstable and causing the grinding head to shake, thereby ensuring that the nails can be polished normally. At the same time, the sliding between the connecting roller and the smooth sliding plate can enable the driving motor to normally drive the connecting roller to rotate and perform the grinding work, and through the connection between the fixed roller and the arc groove, the connection between the driving motor and the connecting roller can be made more stable, avoiding the shaking of the connecting roller and the grinding head.

[0023] like Figure 1-3 As shown, the utility model provides a technical solution: a clamping device for an electric grinder, comprising a grinder body 1, a control switch 2 capable of turning on the grinder body 1 is arranged at the periphery of the grinder body 1 near the bottom, and symmetrically arranged protrusions 3 for users to hold are arranged near the top of the periphery of the grinder body 1, a connecting roller 4 is arranged at the top of the grinder body 1, and a grinding head 5 capable of grinding nails is arranged at the top of the connecting roller 4, and the nails can be stably ground by the grinding head 5, and three electric push rods 31 are equidistantly arranged inside the protrusion 3, and an arc-shaped clamping plate 32 is arranged at the output end of the electric push rod 31 corresponding to the outer diameter of the connecting roller 4, and a sliding plate 33 that reduces the friction between the connecting roller 4 and the connecting roller 4 is arranged on the side of the arc-shaped clamping plate 32 close to the connecting roller 4, which can clamp and limit the connecting roller 4 while avoiding affecting the rotation of the connecting roller 4.

[0024] Example 2

[0025] like Figure 1-3 As shown, a connecting groove 41 for connection is provided on the periphery of the connecting roller 4 and at one end away from the grinding head 5 and located at the top of the grinder body 1, and an arc groove 42 for fixed connection is provided on the periphery of the connecting roller 4 near the bottom, and the connection groove 41 facilitates the connection between the connecting roller 4 and the grinder body 1.

[0026] A driving motor 11 capable of driving the connecting roller 4 to rotate is provided inside the grinder body 1, and a fixed roller 12 connected to the arc groove 42 is symmetrically fixed at the output end of the driving motor 11. The fixed roller 12 slides to the closed part of the arc groove 42 and is engaged with the arc groove 42, so that the connecting roller 4 can be effectively driven to rotate through the driving motor 11.

[0027] A circuit board 13 capable of controlling the start and stop of the drive motor 11 is arranged inside the grinder body 1 and at the bottom of the drive motor 11, and a battery 14 capable of powering the drive motor 11 is arranged at the bottom of the circuit board 13.
