[0025] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0026] like Figure 1 , Figure 2 , Figure 3 As shown, the utility model is an electric screwdriver quick switching device, comprising a motor 1, the output end of the motor 1 is connected to a hexagonal mounting tube 2, a hexagonal mounting platform 3 is slidably mounted in the hexagonal mounting tube 2, a first spring 4 is installed between the hexagonal mounting platform 3 and the hexagonal mounting tube 2, a spring mounting groove 5 is provided on the top side of the hexagonal mounting platform 3, a first latch 6 is slidably mounted in the spring mounting groove 5, and a second spring 7 is installed between the first latch 6 and the spring mounting groove 5;

[0027] An electric screwdriver bit 8 is slidably mounted in the hexagonal mounting platform 3, and a slot 9 is provided on the top side of the electric screwdriver bit 8;

[0028] The hexagonal mounting platform 3 is provided with a hexagonal spring mounting groove 10 at the lower side of the spring mounting groove 5, a second latch 11 is slidably mounted in the hexagonal spring mounting groove 10, a cone head 12 is mounted on the second latch 11, and the cone head 12 has a size matching the slot 9, and a return spring 111 is installed between the hexagonal spring mounting groove 10 and the second latch 11;

[0029] The hexagonal mounting tube 2 is provided with a first through hole 13 and a second through hole 14 whose specifications and sizes match the first latch 6, and the first through hole 13 and the second through hole 14 are both matched with a pressing component 15;

[0030] The pressing component 15 includes a pressing cylinder 151 installed on the hexagonal mounting cylinder 2 . A button 152 is slidably installed on the pressing cylinder 151 . A third spring 153 is installed between the button 152 and the pressing cylinder 151 .

[0031] In this embodiment, when using an electric screwdriver quick switching device, when the electric screwdriver head 8 needs to be disassembled, the button 152 at the position of the first through hole 13 is pressed. Under the resistance of the button 152, the first latch 6 moves toward the spring mounting groove 5, so that the first latch 6 is disengaged from the first through hole 13. Under the effect of the first spring 4, the hexagonal mounting platform 3 moves downward in the hexagonal mounting cylinder 2. When the second latch 11 moves to the position of the second through hole 14, under the effect of the return spring 111, the second latch 11 enters the second through hole 14, so that the cone head 12 is disengaged from the slot 9, and the electric screwdriver head 8 loses the limit from the cone head 12, and the electric screwdriver head 8 can be directly taken out, which is convenient and quick. Only the button 152 at the position of the first through hole 13 is required;

[0032] When the electric screwdriver bit 8 needs to be installed, the electric screwdriver bit 8 to be replaced is inserted into the hexagonal mounting platform 3, and the pressure in the direction of the hexagonal mounting platform 3 is maintained, and the button 152 at the position of the second through hole 14 is pressed, thereby pushing the second plug 11 located in the second through hole 14. After the second plug 11 is disengaged from the second through hole 14, under the pressure of the electric screwdriver bit 8, the user can obviously feel the contact between the electric screwdriver bit 8 and the push head 12, and continues to press the electric screwdriver bit 8. Under the effect of the cone head 12, the second plug 11 enters the second through hole 14 again, but when the plug on the electric screwdriver bit 8 When the slot 9 is at the position of the cone head 12, the user who presses the button 152 at the position of the second through hole 14 will find that the button 152 can be pressed again, and the cone head 12 enters the slot 9, and the second latch 11 again escapes from the second through hole 14. At this time, continuing to press the electric screwdriver bit 8 can drive the hexagonal mounting table 3 to move in the hexagonal mounting tube 2 until the first latch 6 is inserted into the first through hole 13. The hexagonal mounting tube 2 completes the position fixation of the hexagonal mounting table 3. At this time, the second latch 11 is restricted by the inner wall of the hexagonal mounting tube 2 and cannot move, that is, the fixed installation of the electric screwdriver bit 8 is completed;

[0033] Furthermore, when the second pin 11 is in the second through hole 14, if no pressure is applied to the electric screwdriver bit 8, the button 152 at the position of the second through hole 14 can be pressed, and the hexagonal mounting table 3 can be taken out of the hexagonal mounting tube 2 step by step for maintenance and replacement. By installing the hexagonal mounting table 3 with different electric screwdriver bit 8 mounting slots, it can be adapted to the installation of electric screwdriver bits 8 of corresponding specifications, thereby expanding the scope of application.

[0034] Preferably, the pressing cylinder 151 is installed by means of screws. Such a design ensures the fixing effect while facilitating disassembly and replacement. In fact, the installation method of the pressing cylinder 151 can also be considered according to specific circumstances.

[0035] Preferably, the third spring 153 is a rubber-coated spring. Such a design is rust-proof. In fact, protective measures for the third spring 153 may also be considered according to specific circumstances.

[0036] Preferably, the cross section of the cone head 12 is triangular, and only the end of the cone head 12 enters the slot 9. Such a design is prone to displacement when subjected to force. In fact, the structural shape of the cone head 12 can also be considered according to specific circumstances.

[0037] Preferably, the pressing cylinder 151, the hexagonal mounting cylinder 2 and the spring mounting groove 5 are all equipped with a cover 16, and the cover 16 is provided with an avoidance hole 17. Such a design prevents the corresponding button 152, the first latch 6 and the second latch 11 from falling out without interfering with the movement of the corresponding button 152, the first latch 6 and the second latch 11. In fact, a structure that prevents the corresponding button 152, the first latch 6 and the second latch 11 from falling out without interfering with the movement of the corresponding button 152, the first latch 6 and the second latch 11 can also be considered according to specific circumstances.

[0038] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the relevant technical field without departing from the spirit and technical ideas disclosed in the present invention shall still be covered by the claims of the present invention.
