Specific embodiments

[0026] Embodiments of the present utility model will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation to the present utility model.

[0027] Embodiment 1: As Figures 1-6 ;

[0028] It includes a connecting rod 1, and a connecting component 2 is arranged on the connecting rod 1. The connecting component 2 can quickly connect and disassemble the drill bit and the screwdriver bit.

[0029] The connecting component 2 includes a groove 21 and a spring piece 22. A groove 21 is opened on the outer wall of one end of the connecting rod 1. The inner side of the groove 21 is used for assembling and installing the spring piece 22. The spring piece 22 is sleeved on the inner side of the groove 21. After the spring piece 22 is bent into a C shape, it is installed in the groove 21. A through hole one 221 is opened on the inner wall of the spring piece 22, and the through hole one 221 is used for mutually clamping with the steel ball 23. The two ends of the spring piece 22 are mutually clamped. The spring piece 22 is used for limiting the steel ball 23. When the steel ball 23 is pushed up, the spring piece 22 then reversely pushes the steel ball 23 into the groove of the screwdriver bit. A through hole two 27 is opened in the groove 21, and the steel ball 23 is placed in the through hole two 27. The steel ball 23 can move up and down in the through hole two 27. A limiting block is arranged at the bottom of the through hole two 27, so that the lower end of the steel ball 23 cannot break away from the through hole two 27, but a part of the volume of the steel ball 23 can be inserted into the groove of the screwdriver bit for limiting. The steel ball 23 is also inserted into the through hole one 221. An arc-shaped groove 24 is opened at one end of the connecting rod 1. The arc-shaped groove 24 is used for guiding the screwdriver bit, facilitating the screwdriver bit to be inserted into the hexagonal groove 241. The hexagonal groove 241 is used for fitting and plugging connection with the screwdriver bit. The screwdriver bit is further limited by the steel ball 23, so that the screwdriver bit can not only be stably connected to the connecting rod 1, but also be easily disassembled and separated from the connecting rod 1. A hexagonal groove 241 is opened in the arc-shaped groove 24. A threaded groove 25 is opened at the other end of the connecting rod 1. The threaded groove 25 is used for quickly connecting the drill bit 26 by thread, so as to quickly connect the drill bit 26 and the screwdriver bit. After the drill bit 26 is used, the connecting rod 1 can be quickly disassembled, facilitating the screwdriver bit to continue to work. The threaded groove 25 and the hexagonal groove 241 are communicated. The drill bit 26 is threadedly installed in the threaded groove 25. An anti-slip layer 28 is arranged on the outer wall of the connecting rod 1. By means of the anti-slip layer 28, the friction force on the outer wall of the connecting rod 1 is increased, and the anti-slip property of the connecting rod 1 is increased.

[0030] Embodiment 2: As Figure 7 ;

[0031] It includes a connecting rod 1, and a connecting component 2 is arranged on the connecting rod 1. The connecting component 2 can quickly connect and disassemble the drill bit and the screwdriver bit.

[0032] The connecting component 2 further includes a storage mechanism 29. The storage mechanism 29 includes a first support piece 291 and a second support piece 292. The first support piece 291 and the second support piece 292 are respectively installed on the side wall of the connecting rod 1. Through the first support piece 291 and the second support piece 292, not only can the drill bit 26 be supported and placed to prevent the drill bit 26 from being easily lost due to random placement, but also by holding the first support piece 291 and the second support piece 292 and rotating, the connecting rod 1 can be rotated, making it more convenient to rotate the connecting rod 1. Through holes three 293 are opened inside both the first support piece 291 and the second support piece 292, and rubber layers 294 are installed in the through holes three 293. The drill bit 26 is inserted inside the rubber layer 294 for supporting and placing the drill bit 26, and it can also prevent the drill bit 26 from being easily detached.

[0033] The working principle of the present utility model is as follows: A groove 21 is opened on the outer wall of one end of the connecting rod 1. A spring piece 22 is sleeved inside the groove 21. A through hole one 221 is opened on the inner wall of the spring piece 22. The two ends of the spring piece 22 are clamped with each other. A through hole two 27 is opened inside the groove 21. A steel ball 23 is placed inside the through hole two 27, and the steel ball 23 is also inserted inside the through hole one 221. An arc-shaped groove 24 is opened at one end of the connecting rod 1, and a hexagonal groove 241 is opened inside the arc-shaped groove 24. A threaded groove 25 is opened at the other end of the connecting rod 1, and the threaded groove 25 communicates with the hexagonal groove 241. A drill bit 26 is threadedly installed inside the threaded groove 25. An anti-slip layer 28 is provided on the outer wall of the connecting rod 1. The first support piece 291 and the second support piece 292 are respectively installed on the side wall of the connecting rod 1. Through holes three 293 are opened inside both the first support piece 291 and the second support piece 292, and rubber layers 294 are installed in the through holes three 293. One end of the bit is connected to the electric drill, and the other end of the bit is inserted into the hexagonal groove 241 through the arc-shaped groove 24. The side wall of the bit presses the steel ball 23, and the steel ball 23 jacks up the spring piece 22. As the bit moves, the spring piece 22 pushes a part of the volume of the steel ball 23 into the groove of the bit. The steel ball 23 limits the bit, enabling the bit to be not only stably connected to the connecting rod 1 but also easily disassembled and detached from the connecting rod 1. One end of the drill bit 26 is threadedly installed into the threaded groove 25, so that the drill bit 26 is connected to the connecting rod 1, thus quickly connecting the drill bit 26 and the bit. Through the first support piece 291 and the second support piece 292, not only can the drill bit 26 be supported and placed to prevent the drill bit 26 from being easily lost due to random placement, but also by holding the first support piece 291 and the second support piece 292 and rotating, the connecting rod 1 can be rotated, making it more convenient to rotate the connecting rod 1. Through the connecting rod 1, the drill bit 26 and the bit are quickly detachably connected to play a role in connection. By using the rotational torque of the electric drill to drive the bit and the drill bit 26 to rotate, the drill bit 26 is driven to drill holes in the workpiece or the wall. Randomly and quickly pull down the connecting rod to separate the bit for the next step of installing screws, improving the working efficiency of drilling holes and installing screws.

[0034] Although the present utility model has been described above with reference to the embodiments, various improvements can be made thereto and components thereof can be replaced with equivalents without departing from the scope of the present utility model. In particular, as long as there is no structural conflict, the features in the embodiments disclosed by the present utility model can be combined with each other in any way, and the exhaustive description of these combinations is not given in this specification only for the consideration of saving space and resources. Therefore, the present utility model is not limited to the specific embodiments disclosed in the text, but includes all technical solutions falling within the scope of the claims.
