Step 3: Fix the screw placement device on the workbench for assembling the car seat frame and adjust the angle; Step 4: Attach the screw mounting device to the worker’s arm; Step 5: Use the screw installation device to remove the screw 12 on the screw placement device, and use the screw 12 to assemble and connect the other parts into a whole. The seat cushion frame and the backrest frame are rotationally connected, and the rotating shaft is respectively connected to the seat cushion frame and the backrest frame through screws. In addition, the bottom of the seat cushion frame also needs to install the slide rail structure through screws. Only then is the assembly of the car seat frame completed.

[0020] In order to make the operation more convenient, Figure 1 , 2 As shown in 3, the screw installation device in steps 4 and 5 includes a mounting sleeve 1 made of plastic, the mounting sleeve 1 is elastic, an electric screwdriver 2 is provided on the top of the mounting sleeve 1, and the front end of the electric screwdriver 2 is magnetic, which is convenient for adsorbing the screw 12; A handle 7 is provided on the front side of the mounting sleeve 1, and the handle 7 is located at a lower front side of the mounting sleeve 1. A plurality of control buttons 8 are provided at the outer end of the handle 7. Connecting arms 6 are provided at both ends of the handle 7, and one end of the connecting arm 6 is connected to the mounting sleeve 1. The two connecting arms 6 are respectively located on both sides of the mounting sleeve 1.

[0021] A plurality of straps 4 are fixedly provided on one side of the installation sleeve 1 , and a plurality of fixing buckles 9 are fixedly provided on the other side of the installation sleeve 1 .

[0022] Put the elastic installation sleeve 1 on the worker's arm, with the front end of the installation sleeve 1 close to the wrist and the rear end close to the elbow. Then, wrap the strap 4 around the bottom end of the installation sleeve 1 and fix it on the corresponding fixing buckle 9, so that the installation sleeve 1 is tied to the worker's forearm. The electric screwdriver 2 is elastic, and the strap 4 can also control the tightness, so as to be suitable for different arm sizes. The electric screwdriver 2 fixed on the top of the installation sleeve 1 can rotate to drive the screw 12 to rotate, so as to install the car seat frame. Since the electric screwdriver 2 is fixed on the worker's arm through the installation sleeve 1, it is not necessary to hold it with the palm during use. The palm can be freed so that both hands can be used to take and place parts, adjust the position of the seat frame, etc. during the assembly process, making the two-hand operation more convenient; When the electric screwdriver 2 is needed to drive the screw 12 to rotate, the palm of the arm where the installation sleeve 1 is located is bent downward and grasped at the outer end of the handle 7, and the screw installation device is operated by pressing the corresponding control button 8. The palm is bent downward and the handle 7 is grasped, and the back of the hand can be kept away from the electric screwdriver 2 at the same time, so as to avoid injury to the arm caused by the electric screwdriver 2 during rotation.

[0023] The electric screwdriver 2 mounted on the mounting sleeve 1 can move freely forward and backward. Figure 1 , 2 As shown, the top of the mounting sleeve 1 is slidably connected to a slide seat 10, the top of the slide seat 10 is provided with a detachable fastening plate 3, and the electric screwdriver 2 is clamped between the fastening plate 3 and the slide seat 10; An electric push rod 5 is provided on one side of the electric screwdriver 2, and the rear end of the electric push rod 5 is fixedly connected to the mounting sleeve 1.

[0024] When the worker is performing other assembly operations with both hands, the electric screwdriver 2 is in a retracted state at the top of the installation sleeve 1, and the front end of the electric screwdriver 2 is located at the back of the palm. When the electric screwdriver 2 is needed to work, the electric push rod 5 is controlled to extend forward by the corresponding control button 8, and the electric push rod 5 is able to push the electric screwdriver 2 forward, so that the electric screwdriver 2 slides forward under the action of the slide seat 10, and the front end of the electric screwdriver 2 is able to extend forward to the front side of the palm, thereby changing to a use state for work.

[0025] In order to facilitate the use of screws 12, Figure 4 , 5As shown, the screw placement device in steps three and five includes a storage plate 11, a plurality of placement holes 1101 are opened on the top of the storage plate 11, a detachable plastic ring 1102 is provided on the inner wall of the placement hole 1101, the screws 12 correspond to the placement holes 1101 one by one, the bottom end of the screw 12 extends to the inside of the placement hole 1101 and is connected to the plastic ring 1102 by a thread, screws 12 of different models and sizes are respectively arranged in different areas on the storage plate 11, and the screws 12 are made of iron.

[0026] In the prior art, the storage plate 11 is mostly placed randomly in the packaging box. When in use, the screw 12 needs to be taken out and then tightened by the electric screwdriver 2. When tightening, one end of the screw 12 is aligned with the installation hole, and the other end is aligned with the electric screwdriver 2. This requires two-handed operation, which is relatively cumbersome. In this assembly process, the screw 12 is pre-screwed into the placement hole 1101. When taking it out, the worker first aligns the front end of the electric screwdriver 2 with the corresponding screw 12, and drives the screw 12 to rotate by the electric screwdriver 2 to screw it out from the corresponding placement hole 1101. The screwed screw 12 is naturally adsorbed on the front end of the electric screwdriver 2 by suction, and the electric screwdriver 2 drives the screw 12 to move and align it with the installation position, and then the screw 12 is tightened at the installation position. In this way, the step of manually taking out the screw 12 can be saved, and it can be operated with only one hand, making the assembly process more convenient. The plastic ring 1102 is made of plastic, which is convenient for replacement after wear.

[0027] In order to facilitate the use of screws 12, Figure 4 , 6 As shown in , 7, a mounting plate 14 is provided at the bottom of the storage plate 11, and the mounting plate 14 is fixed on the workbench. The top of the mounting plate 14 is rotatably connected to an adjustment platform 13 through a damping shaft. The top of the adjustment platform 13 is hinged with a lifting plate 15. The storage plate 11 is arranged at the top of the lifting plate 15. The rotation of the lifting plate 15 can adjust the inclination angle of the storage plate 11; A clamping plate is fixedly provided on the top of the lifting plate 15 , and the bottom end of the storage plate 11 is inserted into the inside of the clamping plate. The clamping plate is provided with fastening bolts through threads, and the storage plate 11 is fixed to the lifting plate 15 by the fastening bolts.

[0029] Insert the bottom end of the storage plate 11 into the clamping plate, tighten the fastening bolts to fix the storage plate 11 so that it is fixed on the lifting plate 15, and then rotate the sleeve 16. Since the sleeve 16 is threadedly connected to the support screw 18, after the sleeve 16 is rotated, the support screw 18 can be extended and retracted in the sleeve 16, changing the overall length of the sleeve 16 and the support screw 18, thereby adjusting the inclination angle of the lifting plate 15 and the storage plate 11. The adjusting platform 13 can also be rotated to adjust the angle of the storage plate 11 in the horizontal direction. After adjustment, the storage plate 11 and the screw 12 at the top thereof are facing the worker, so that the worker can unscrew the screw 12 with the electric screwdriver 2.
