Specific embodiments

[0024] The preferred embodiments of the present utility model will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are only descriptive and exemplary, and should not be construed as limiting the protection scope of the present utility model.

[0025] It should be noted that like reference numerals represent similar items in the following drawings. Therefore, once an item is defined in one drawing, it may not be further defined and explained in subsequent drawings.

[0026] This embodiment mainly elaborates on the switch button structure of the power tool, as follows:

[0027] As Figures 1 - 6As shown in the figure, the switch button structure of the power tool includes a body 1, a button 2 for starting the body 1 is arranged on the body 1, the button 2 is rotatably connected to the body 1, the button 2 includes an abutting end 22 and a pressing end 21, the abutting end 22 of the button 2 abuts against the control end of the switch device 5 in the body 1, the pressing end 21 of the button 2 is outside the body 1, the button 2 is integrally formed, a through groove 8 and a first accommodating cavity 10 are formed on the button 2, a second accommodating cavity 6 is formed on the inner side surface of the button 2, the second accommodating cavity 6 is located on the side of the through groove 8 away from the first accommodating cavity 10, the through groove 8 is communicated with the first accommodating cavity 10, a rotating shaft 9 is arranged in the through groove 8, a locking member is arranged on the rotating shaft 9, a protrusion 4 which is in mutual abutting and cooperating with the locking member is arranged on the body 1, the protrusion 4 is located below the bottom of the first accommodating cavity 10, a groove 13 which is matched with the protrusion 4 is formed on the inner side of the button 2, the groove 13 is located at the bottom of the first accommodating cavity 10, the locking member includes a rotating part 31, the rotating part 31 is sleeved on the rotating shaft 9, the rotating part 31 is rotatably connected to the rotating shaft 9, both ends of the rotating part 31 extend outwards to form the pressing part 32 and the abutting part 33, a first assembly groove 12 is formed on the inner wall of the pressing part 32, a second assembly groove 11 is formed on the button 2, the second assembly groove 11 is located in the first accommodating cavity 10, a torsion spring 7 is also sleeved on the rotating shaft 9, the first end of the torsion spring 7 abuts against the first assembly groove 12 on the pressing part 32, and the second end of the torsion spring 7 abuts against the second assembly groove 11 in the first accommodating cavity 10.

[0028] When an electric tool needs to be used, first, the user presses the pressing part 32 of the locking part 3 towards the first accommodation cavity 10. In this case, the rotating part 31 of the locking part 3 rotates around the rotating shaft 9. Thus, the pressing part 32 of the locking part 3 enters the first accommodation cavity 10, and the abutting part 33 of the locking part 3 moves away from the protrusion 4 on the machine body 1 and enters the second accommodation cavity 6. Then, the user presses the pressing end 21 of the button 2. In this case, the pressing end 21 of the button 2 contacts and fits with the surface of the machine body 1. Consequently, the abutting end 22 of the button 2 abuts against the control end of the switch device 5, so that the switch device 5 is in the on state. In this way, the electric tool starts. Therefore, when starting the electric tool, the user needs to first adjust the locking part 3, and then can start the electric tool by pressing the button 2. Thus, the setting of the locking part 3 can limit the button 2, avoiding the situation that the user accidentally presses the button 2 to start the electric tool. This can prevent the problem of damage to other objects, the electric tool itself, and the human body caused by the accidental start of the electric tool, thereby improving the safety of the electric tool. The setting of the torsion spring 7 is such that when the user no longer presses the pressing part 32 of the locking part 3, since the first end of the torsion spring 7 is located in the first assembly groove 12 on the pressing part 32 and the second end of the torsion spring 7 is located in the second assembly groove 11 in the first accommodation cavity 10, due to the elasticity of the torsion spring 7, it can push the locking part 3 to rotate in the through groove 8. Thus, the pressing part 32 and the abutting part 33 of the locking part 3 respectively disengage from the first accommodation cavity 10 and the second accommodation cavity 6. In this case, the locking part 3 can support the button 2, making the pressing end 21 of the button 2 no longer contact and fit with the surface of the machine body 1 and move away from the machine body 1. At the same time, the abutting end 22 of the button 2 no longer abuts against the control end of the switch device 5. In this way, the switch device 5 is in the off state, and the electric tool stops working. Thus, the setting of the torsion spring 7 improves the reliability of the locking part 3, and further improves the safety of the electric tool. The settings of the first assembly groove 12 and the second assembly groove 11 can make the connection between the torsion spring 7 and the locking part 3 and the button 2 more stable. Among them, the setting of the protrusion 4 can prevent the abutting part 33 of the locking part 3 from slipping on the surface of the machine body 1. Thus, the setting of the protrusion 4 further improves the reliability of the locking part 3. Through the setting of the groove 13, when the button 2 fits with the surface of the machine body 1, the protrusion 4 is located in the groove 13. This can prevent the protrusion 4 from affecting the fitting effect between the button 2 and the machine body 1. Similarly, the settings of the first accommodation cavity 10 and the second accommodation cavity 6 can accommodate the abutting part 33 and the pressing part 32, which can further improve the fitting effect between the button 2 and the machine body 1, thereby improving the aesthetics of the electric tool.
