[0026] Please refer to Figures 1-6 The above technical solutions will be described in detail by the following embodiments of the utility model:

[0027] A locking device with safety protection function, including electric screwdriver fixed plate 1, electric screwdriver fixed plate 1 is fixedly installed with electric screwdriver 2 and pneumatic cylinder 3, electric screwdriver fixed plate 1 bottom is fixedly installed with the shroud 4, the inside hollow of shroud 4, its inside is installed with screw placement cylinder 7, one side of screw placement cylinder 7 is fixedly installed with connecting plate 6, the piston rod end of connecting plate 6 and pneumatic cylinder 3 is fixed, the infrared sensor 5 of the human body infrared signal can be inducted on shroud 4, the both sides of screw placement cylinder 7 are installed with aperture adjusting part 76.

[0028] Preferably, the two side surfaces of the shroud 4 are respectively provided with a first side hole 8 and a second side hole 9, the first side hole 8 provides a moving space for the up-down movement of the connecting plate 6, and the second side hole 9 provides a moving space for the up-down movement of the aperture adjusting part 76.

[0029] Preferably, the screw placement cylinder 7 comprises a center cylinder frame 71, one side of the center cylinder frame 71 is fixedly installed with a screw feeding pipe 72, the other side is fixed with the connecting plate 6, and the lower end of the center cylinder frame 71 is fixedly installed with a clamp mouth connecting frame 74.

[0030] Preferably, two symmetrical clamp mouths 75 are rotatably installed on the clamp mouth connecting frame 74, and the aperture adjusting part 76 is installed on the side surface of the clamp mouth 75.

[0031] It should be noted that the clip 75 is rotatably mounted on the clip connecting frame 74 through a rotating shaft arranged at the middle position of the clip 75, and a spring is arranged between the upper half of the clip 75 and the clip connecting frame 74, so that the clip 75 can be automatically reset after being opened.

[0032] Preferably, a batch rod through hole 77 is arranged at the inner center position of the clip connecting frame 74, and a screw discharging hole 78 is arranged at the inner side position of the clip connecting frame 74, which is opposite to and communicates with the screw feeding pipe 72.

[0033] Preferably, a screw groove 79 is arranged in the clip 75, which simultaneously communicates with the batch rod through hole 77 and the screw discharging hole 78.

[0034] Preferably, the aperture adjusting member 76 comprises an adjusting block 763 which can extend into the screw groove 79, and a driving part for driving the adjusting block 763 to move.

[0035] It should be noted that the clip 75 is rotatably mounted on the clip connecting frame 74 through a rotating shaft arranged at the middle position of the clip 75, and a spring is arranged between the upper half of the clip 75 and the clip connecting frame 74, so that the clip 75 can be automatically reset after being opened.

[0036] Further, the driving part comprises a U-shaped frame 761 fixed to the side surface of the clip 75, a adjusting screw 762 threadedly connected to the U-shaped frame 761, the end of the adjusting screw 762 rotatably connected with the adjusting block 763, a knob 764 fixed to the end of the adjusting screw 762, a connecting ring 765 rotatably connected to the adjusting screw 762 through a bearing, a connecting rod 766 fixedly arranged on the connecting ring 765, a scale plate 767 fixed to the U-shaped frame 761 arranged on one side of the connecting rod 766, a strip hole 768 arranged in the scale plate 767, the end of the connecting rod 766 extending into the strip hole 768 and abutting to the inner wall of the strip hole 768, and a pointer 769 arranged at the end of the connecting rod 766 and pointing to the scale on the surface of the scale plate 767.

[0037] If the size of the screw to be locked is small, to prevent it from falling into the screw groove 79 and being unable to automatically reach the vertical state due to the small size, the inner diameter of the screw groove 79 can be adjusted in advance by the hole diameter adjusting piece 76. The specific adjustment method is to rotate the knob 764 to drive the adjusting screw 762 to rotate. Since the adjusting screw 762 is threadedly connected with the U-shaped frame 761, the adjusting screw 762 will move forward when it rotates, thereby pushing the adjusting block 763 to move forward and extend into the screw groove 79. After the adjusting blocks 763 on both sides extend into the inside of the screw groove 79, the inner diameter of the screw groove 79 is indirectly reduced. In this way, the small-sized screw that falls into the screw groove 79 can also automatically reach the vertical state under the limiting action of the adjusting block 763. At the same time, the rotation of the adjusting screw 762 will drive the connecting ring 765 on it to move. However, due to the rotary connection between them, the connecting ring 765 will not rotate synchronously with the adjusting screw 762 but will move synchronously. When the connecting ring 765 moves, the pointer 769 at the end of it moves synchronously. Therefore, the distance that the adjusting block 763 moves forward can be observed very intuitively through the pointer 769, and the distance that the adjusting block 763 needs to adjust can be accurately judged according to the size of the screw.

[0038] Further, the side of the adjusting block 763 opposite to the screw groove 79 is an inclined surface, and an arc-shaped groove is arranged on the inclined surface. This arrangement can make the falling screw directly fall on the inclined surface, thereby falling into the screw groove 79, and the arrangement of the arc-shaped groove is more conducive to the screw reaching the vertical state.

[0039] Specific use, the screw is put into the screw feeding pipe 72, the screw falls into the screw groove 79, the electric screwdriver 2 and the air cylinder 4 are started, the air cylinder 4 drives the clamp nozzle 75 to move down, so that the clamp nozzle 75 can contact the product surface, and the screwdriver rod on the electric screwdriver 2 can lock the screw to the product surface, in actual use, if the clamp nozzle 75 accidentally aims at the human body, at this time, the infrared sensor 5 can sense the infrared signal of the human body, so as to make the electric screwdriver 2 and the air cylinder 4 stop working, thereby effectively protecting the human body and playing a safety protection role, and in actual use, different sizes of screws need to be installed on different products, if the size of the screw to be locked is small, to prevent it from falling into the screw groove 79 inside due to the small size and possibly unable to automatically reach the vertical state, the inner diameter of the screw groove 79 can be adjusted in advance by the hole diameter adjusting part 76, the specific adjusting mode is that the knob 764 drives the adjusting screw 762 to rotate, since the adjusting screw 762 and the U-shaped frame 761 are screw connected, the adjusting screw 762 will move forward when rotating, thereby pushing the adjusting block 763 to move forward and extending into the screw groove 79, after the adjusting block 763 on both sides extends into the screw groove 79, the inner diameter of the screw groove 79 is indirectly reduced, in this way, the screw with smaller size falling into the screw groove 79 can also automatically reach the vertical state under the limiting action of the adjusting block 763, at the same time, the rotation of the adjusting screw 762 drives the connecting ring 765 to move, but since the two are rotationally connected, the connecting ring 765 will not rotate synchronously with the adjusting screw 762 but will move synchronously, the pointer 769 at the tail end of the connecting ring 765 moves synchronously when the connecting ring 765 moves, so the distance of the adjusting block 763 moving forward can be observed very intuitively by the pointer 769, and the distance of the adjusting block 763 needing to be adjusted can be accurately judged according to the size of the screw, which is very convenient.
