Figure 8 , 9 As shown, the fixed structure 11 is provided with two first sliding grooves 17 and two second sliding grooves 18 which are symmetrical in vertical direction; a limiting ring 19 is fixedly installed in the circular hole of the fixed structure 11, as shown in FIG. Figure 6 As shown, the fixing member delivery pipe 13 is installed on one side of the fixing structure 11 and the fixing member delivery pipe 13 is communicated with the fixing structure 11; Figure 3 , 4 As shown, the fixing member is fixedly mounted on the mounting slide 7; Figure 7 , 10 As shown, two opening and closing swing plates 16 are symmetrically mounted on the upper and lower sides of the fixed structure 11. Figure 5 As shown, a first leaf spring 12 is installed between the opening and closing swing plate 16 and the fixed structure 11; the opening and closing swing plate 16 has an extrusion surface 40 on the side close to the hinge axis, and the inner wall surface of the opening and closing swing plate 16 is a semicircular surface; Figure 5 As shown, the extrusion surfaces 40 of the two opening and closing swing plates 16 pass through the two first slide grooves 17 opened on the fixed structure 11 and are located in the circular holes on the inner side of the fixed structure 11; Fig.11 As shown, the opening and closing swing plate 16 is provided with a first installation cavity 26 and a second installation cavity 27, the first installation cavity 26 and the second installation cavity 27 are communicated with each other, the second installation cavity 27 passes through the inner wall surface of the opening and closing swing plate 16, and the first installation cavity 26 is provided with a third slide groove 31 penetrating the inner wall surface of the opening and closing swing plate 16 on the side away from the first installation cavity 26; the limiting block 25 is installed in the first installation cavity 26; one end of the push block 20 has an inclined surface 32, the push block 20 is slidably installed in the first installation cavity 26, and a push plate 33 is fixedly installed on the side of the push block 20 close to the inner wall surface of the opening and closing swing plate 16, and the push plate 33 passes through the third slide groove 31 opened on the opening and closing swing plate 16; the installation slide block 21 is slidably installed In the first mounting cavity 26, a pendulum bar 24 is swingably mounted on the mounting slider 21 through a mounting lug 29, and a second leaf spring 30 is mounted between the pendulum bar 24 and the mounting slider 21; one end of the pendulum bar 24 has an arc-shaped bar, and the other end of the pendulum bar 24 has an inclined plate 34, and the inclined plate 34 cooperates with the inclined surface 32 on the push block 20; a three-stage telescopic rod 22 is mounted between the mounting slider 21 and the inner end surface of the first mounting cavity 26, and a spring 23 is nested and mounted on the outer side of the three-stage telescopic rod 22, and the spring 23 is a compression spring 23 and has a preload, and the elastic force of the spring 23 is greater than the elastic force of the second leaf spring 30; one end of the pendulum bar 24 with the arc-shaped bar is located in the second mounting cavity 27.

[0039] like Figure 3 ,5 As shown, a conical trigger ring 9 is fixedly mounted on the screwdriver 6 , and the trigger ring 9 cooperates with the extrusion surface 40 of the opening and closing swing plate 16 .

[0040] When tightening the screw 14, the screwdriver 6 is driven forward, and the movement of the screwdriver 6 drives the trigger ring 9 to move. During the movement, when the front end of the screwdriver 6 cooperates with the screw 14, the servo motor 1 is controlled to work, and the servo motor 1 controls the screwdriver 6 to rotate to tighten the bolt. When the screw 14 is screwed in half, the trigger ring 9 just contacts the extrusion surface 40 of the two opening and closing swing plates 16. At this time, the screwdriver 6 continues to move forward to squeeze the two opening and closing swing plates 16 through the extrusion surface 40, so that the two opening and closing swing plates 16 are forced to open. The opening of the two opening and closing swing plates 16 drives the two limiting structures 15 to open, that is, the screw 14 is disengaged from the two opening and closing swing plates 16, and the screw 14 can continue to be screwed in without being restricted by the two opening and closing swing plates 16; the installation of the screw 14 is achieved.

[0041] like Figure 5 , 12 As shown, the fixing member includes a screw 14 and a clamping member 35 .

[0042] like Fig.14 As shown, the clamping member 35 includes a fixed disk 39, an elastic rod 37, and a limiting protrusion 38, wherein one end of the fixed disk 39 has a conical surface 36, and three elastic rods 37 are evenly fixedly installed on the end of the fixed disk 39 with the conical surface 36, and each elastic rod 37 has a triangular limiting protrusion 38.

[0043] like Figure 5 , 11 As shown, when the screw 14 is used, two limiting structures 15 for limiting the screw 14 from sliding out are fixedly installed at the front ends of the two opening and closing swing plates 16 by bolts, and the two limiting structures 15 are combined to form a block body with a limiting table 28.

[0044] like Fig.12 , 13 As shown, when the clamping piece 35 is used, a push ring 10 is fixedly installed at the front end of the screwdriver 6, and the outer diameter of the push ring 10 is smaller than the distance between the sharp corners of the extrusion surfaces 40 of the two opening and closing swing plates 16; the push ring 10 cooperates with the push plate 33 fixed on the push block 20; the swing bar 24 has an arc-shaped end that cooperates with the fixed plate 39 of the clamping piece 35.

[0045] When the clamping member 35 is used, a push ring 10 is first installed at the front end of the screwdriver 6. When the screwdriver 6 is driven forward, the screwdriver 6 drives the push ring 10 to move. During the movement, when the push ring 10 contacts the two push plates 33, the push ring 10 drives the two push plates 33 to move. The two push plates 33 drive the two push blocks 20 to move. Because the elastic force of the spring 23 is greater than the elastic force of the second leaf spring 30, the two push blocks 20 will first squeeze the swing bar 24 to swing under the action of the upper inclined surface 32 and the upper inclined plate 34 of the swing bar 24, and the arc bar on the swing bar 24 passes through the second installation cavity 2 7 contacts and cooperates with the fixed plate 39 on the corresponding clip 35; after the swing bar 24 swings at a certain angle, the swing bar 24 is limited by the mounting slide block 21 to stop swinging. At this time, pushing it forward will drive the mounting slide block 21 to move forward through the swing bar 24 and the mounting lug 29, and the spring 23 is compressed. At this time, the swing bar 24 moves forward and pushes the fixed plate 39 of the clip 35 forward, that is, the clip 35 moves forward. When the clip 35 is clamped, the staggered structure 3 moves to the right, and the clamped clip 35 will be disconnected from the clip 35 connected to it but not clamped under the pulling force. At this time, the clamping of the clip 35 is completed. When the clamping part 35 is clamped, the screwdriver 6 is controlled to move backward, and the pushing ring 10 loses the thrust on the push plate 33. Under the action of the spring 23, the installation slider 21 will drive the swing bar 24 and the push block 20 to move backward. During the backward movement, the arc bar on the swing bar 24 will contact the fixed plate 39 of the rear side clamping part 35. Under the action of the conical surface 36 on the fixed plate 39, the clamping part 35 is squeezed and swung across the fixed plate 39, and then continues to move backward. When the installation slider 21 is completely reset, the swing bar 24 also swings and resets under the action of the second leaf spring 30, and at this time the arc bar on the swing bar 24 moves to the rear side of the front end clamping part 35, ready for the next clamping.

[0046] like Figure 5 , 12 As shown, a friction sleeve 41 is fixedly installed on the front inner wall surface of the opening and closing swing plate 16; the function of the friction sleeve 41 is to limit the fixing parts blown in from the fixed frame conveying pipe, so as to ensure that the fixing parts can be maintained when there is no external force at the friction sleeve 41, so as to facilitate the subsequent twisting and pushing.

[0047] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any simple modification or equivalent change made to the above embodiment based on the technical essence of the present invention shall fall within the protection scope of the present invention.

[0048] Implementation method: When using the device designed by the present invention, when using the screw 14 to fix the electric sheet, firstly, the servo motor 1 is used to control the screwdriver 6 to move forward, and the movement of the screwdriver 6 drives the trigger ring 9 to move. During the movement, when the front end of the screwdriver 6 cooperates with the screw 14, the servo motor 1 is controlled to work, and the servo motor 1 controls the screwdriver 6 to rotate to tighten the bolt. When the screw 14 is screwed in half, the trigger ring 9 just contacts the extrusion surface 40 of the two opening and closing swing plates 16. At this time, the screwdriver 6 continues to move forward to squeeze the two opening and closing swing plates 16 through the extrusion surface 40, so that the two opening and closing swing plates 16 are forced to open. The opening of the two opening and closing swing plates 16 drives the two limiting structures 15 to open, that is, the screw 14 is disengaged from the two opening and closing swing plates 16, and the screw 14 can continue to be screwed in without being restricted by the two opening and closing swing plates 16; the installation of the screw 14 is achieved.

[0049] When the clamping member 35 is used, a push ring 10 is first installed at the front end of the screwdriver 6. When the screwdriver 6 is driven forward, the screwdriver 6 drives the push ring 10 to move. During the movement, when the push ring 10 contacts the two push plates 33, the push ring 10 drives the two push plates 33 to move. The two push plates 33 drive the two push blocks 20 to move. Because the elastic force of the spring 23 is greater than the elastic force of the second leaf spring 30, the two push blocks 20 will first squeeze the swing bar 24 to swing under the action of the upper inclined surface 32 and the upper inclined plate 34 of the swing bar 24, and the arc bar on the swing bar 24 passes through the second installation cavity 2 7 contacts and cooperates with the fixed plate 39 on the corresponding clip 35; after the swing bar 24 swings at a certain angle, the swing bar 24 is limited by the mounting slide block 21 to stop swinging. At this time, pushing it forward will drive the mounting slide block 21 to move forward through the swing bar 24 and the mounting lug 29, and the spring 23 is compressed. At this time, the swing bar 24 moves forward and pushes the fixed plate 39 of the clip 35 forward, that is, the clip 35 moves forward. When the clip 35 is clamped, the staggered structure 3 moves to the right, and the clamped clip 35 will be disconnected from the clip 35 connected to it but not clamped under the pulling force. At this time, the clamping of the clip 35 is completed. When the clamping part 35 is clamped, the screwdriver 6 is controlled to move backward, and the pushing ring 10 loses the thrust on the push plate 33. Under the action of the spring 23, the installation slider 21 will drive the swing bar 24 and the push block 20 to move backward. During the backward movement, the arc bar on the swing bar 24 will contact the fixed plate 39 of the rear side clamping part 35. Under the action of the conical surface 36 on the fixed plate 39, the clamping part 35 is squeezed and swung across the fixed plate 39, and then continues to move backward. When the installation slider 21 is completely reset, the swing bar 24 also swings and resets under the action of the second leaf spring 30, and at this time, the arc bar on the swing bar 24 moves to the rear side of the front end clamping part 35, ready for the next clamping.
