DETAILED DESCRIPTION

[0039] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

A pull rod 208 is fixedly connected between the two blocking rods 204; the clamping structure 3 includes a mounting frame 301 fixedly connected between the two rotating shafts 202 and two sliders 302 slidably connected in the mounting frame 301, a mounting plate 303 is fixed between the two sliders 302, the mounting plate 303 is slidably connected to the mounting frame 301, a first screw rod 304 is threadedly connected on the mounting plate 303, a fixed plate 305 is slidably connected in the mounting frame 301, the first screw rod 304 is rotatably connected to the fixed plate 305, a first support rod 307 is slidably connected in the mounting frame 301, a second support rod 308 is fixedly connected in the mounting frame 301, and the fixed plate 305 is slidably connected to the first support rod 307 and the second support rod 308.

[0041] Specifically, Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 8 and Fig. 9As shown, a connecting plate 206 is fixedly connected to the lower side of the blocking rod 204, and the connecting plate 206 is slidably connected to the connecting frame 203. A first spring 207 is fixedly connected between the connecting plate 206 and the connecting frame 203. When it is necessary to assemble the parts on the back side of the battery cover, by pulling the pull rod 208 to the left, the pull rod 208 will drive the two blocking rods 204 to slide to the left. When the blocking rod 204 slides, it drives the connecting plate 206 to move to the left. When the connecting plate 206 moves to the left, the first spring 207 contracts, and at the same time, the blocking rod 204 no longer resists the fixed block 205, and then the installation frame 301 can be rotated. , so that the installation frame 301 drives the two rotating shafts 202 to rotate, and the rotation of the rotating shaft 202 drives the fixed block 205 to rotate. When the fixed block 205 rotates 180 degrees, the pull rod 208 is released, so that the blocking rod 204 slides to the right under the action of the first spring 207. At this time, the blocking rod 204 resists and limits the fixed block 205, which is convenient for fixing the rotating shaft 202 and preventing the rotating shaft 202 from rotating on its own. The rotating shaft 202 drives the installation frame 301 to rotate, which is convenient for turning over the battery cover and assembling the components on the back of the battery cover, avoiding the need to disassemble the battery cover for secondary fixation, thereby improving operating efficiency.

[0042] Specifically, Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 7 , Fig. 9 , Fig.12 , Fig.14 and Fig.15As shown, a guide plate 306 is fixedly connected to the right side of the fixed plate 305, and the guide plate 306 is slidably connected to the mounting plate 303. The limiting structure 5 includes two guide columns 501 fixedly connected to the mounting frame 301 and a limiting rod 502 slidably connected to the front slider 302. The two sliders 302 are slidably connected to the two guide columns 501 respectively. A plurality of limiting grooves 503 are provided on the front guide column 501. The limiting rod 502 is engaged with one of the limiting grooves 503. A sliding column 505 is fixedly connected to the limiting rod 502. 505 is slidably connected to the slider 302, and a pull plate 506 is fixedly connected to the top of the slide column 505, and a second spring 504 is fixedly connected between the limit rod 502 and the slider 302. First, the battery cover is placed on the first support rod 307 and the second support rod 308 in the installation frame 301, and at the same time, the pull plate 506 is pulled upward to make the pull plate 506 drive the slide column 505 to move upward. When the slide column 505 slides upward, it drives the limit rod 502 to slide. The limit rod 502 moves upward to make the first spring 207 contract, and at the same time, the limit rod 502 is no longer engaged with the limit groove 503. When the slider 302 slides to the left, the slider 302 moves more smoothly through the guide column 501 when sliding. The slider 302 will drive the mounting plate 303 and the fixing plate 305 to move. When the slider 302 moves to a certain position, the pull plate 506 is released, so that the limit rod 502 is engaged with the other limit groove 503 under the action of the second spring 504, and the front slider 302 is fixed. The slider 302 is fixed by the engagement of the limit rod 502 with the front guide column 501 to prevent the slider 302 from sliding freely. Then, by rotating the first screw rod 304, the first screw rod 304 rotates with the mounting plate 303. The plate 303 is threadedly matched to drive the fixed plate 305 to move to the left. When the fixed plate 305 moves to the left, the guide plate 306 and the mounting plate 303 slide. The setting of the guide plate 306 makes the movement of the fixed plate 305 more stable. At the same time, the fixed plate 305 fixes the battery cover. The position of the fixed plate 305 is adjusted by the slider 302, and then the fixed plate 305 is threadedly driven by the first screw rod 304 to fix the battery cover. When assembling battery covers of different lengths, it is convenient to quickly adjust the position of the fixed plate 305, which can improve the fixing efficiency of the battery cover.

[0043] Specifically, Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 7 , Fig. 9 , Fig.12 , Fig.14 and Fig.15As shown, the first support rod 307 is fixed to the installation frame 301 through the fixing structure 4, and the fixing structure 4 includes two guide rods 401 fixedly connected to the installation frame 301 and a rubber pad 402 slidably connected to the first support rod 307, the first support rod 307 is slidably connected to the guide rod 401, the rubber pad 402 conflicts with the left guide rod 401, a connecting block 403 is fixedly connected to the rubber pad 402, the connecting block 403 is slidably connected to the first support rod 307, a knob 404 is rotatably connected to the left side of the first support rod 307, and the connecting block 403 is threadedly connected to the knob 404. When it is necessary to fix battery covers of different widths, the first support rod 307 slides with the installation frame 301, and the first support rod 307 will slide with the guide rod 401. The setting of the guide rod 401 makes the movement of the first support rod 307 more stable. When the first support rod 307 slides to a certain position, by turning the knob 404, the threaded drive connecting block 403 slides downward when the knob 404 rotates, so that the connecting block 403 drives the rubber pad 402 to move downward, so that the rubber pad 402 and the guide rod 401 are pressed tightly. The rubber pad 402 and the guide rod 401 are pressed tightly by the threaded drive of the knob 404, which is convenient for fixing the first support rod 307 after sliding. Through the sliding cooperation between the first support rod 307 and the mounting frame 301, it is convenient to adjust the position of the first support rod 307 according to the width of the battery cover, so that the first support rod 307 cooperates with the second support rod 308 to place battery covers of different widths.

[0044] Specifically, Figure 1 , Figure 2 , Figure 5 , Fig. 9 , Fig.10 , Fig.11 and Fig.13As shown, the mounting structure 6 includes two adjustment blocks 601 slidably connected to the base 1 and a mounting column 602 fixedly connected to the bottom of the adjustment block 601, a mounting block 603 is slidably connected inside the mounting column 602, a connecting rod 604 is fixedly connected above the mounting block 603, the connecting rod 604 is slidably connected to the mounting column 602, a guide block 605 is fixedly connected to the rear of the connecting rod 604, a fixed rod 606 is slidably connected inside the base 1, and the mounting column 602 is fixedly connected to the fixing rod 606. 06 sliding connection, the guide block 605 is slidably connected to the fixed rod 606, both ends of the fixed rod 606 are fixedly connected with a slide plate 607, the slide plate 607 is slidably connected to the base 1, the base 1 is rotatably connected with a second screw rod 608, the slide plate 607 on the left is threadedly connected to the second screw rod 608, and the adjustment block 601 is fixedly connected with an adjustment plate 609 above. When the base 1 is installed with the mounting hole of the workbench, the mounting column 602 is adjusted according to the position of the mounting hole. The adjusting plate 609 drives the adjusting block 601 to slide, and when the adjusting block 601 slides, the mounting column 602 is driven to move, and the mounting column 602 will slide with the fixing rod 606. When the mounting column 602 moves to a certain position, the two mounting columns 602 are plugged into the mounting holes on the workbench, and then the hexagonal wrench is inserted into the hexagonal groove at the end of the second screw rod 608. The second screw rod 608 rotates, and the second screw rod 608 threads drive the slide plate 607 to slide. When the slide plate 607 slides, it drives the fixing rod 606 to move forward. When the fixing rod 606 moves forward, it drives the connecting rod 604 to move forward through the guide block 605. When the connecting rod 604 moves forward, it drives the mounting block 603 to press against the workbench. When the second screw rod 608 rotates, the two mounting blocks 603 are driven to press against the workbench through threads. When the base 1 is installed between the workbench, the installation efficiency is improved. At the same time, the position of the mounting column 602 can be adjusted, which is convenient for adjusting the position of the mounting column 602 according to the position of the reserved mounting hole on the workbench, thereby improving flexibility.

[0045] When the present invention is in use, the battery cover is first placed on the first supporting rod 307 and the second supporting rod 308 in the installation frame 301, and at the same time, the pulling plate 506 is pulled upward so that the pulling plate 506 drives the sliding column 505 to move upward. When the sliding column 505 slides upward, it drives the limiting rod 502 to slide. The limiting rod 502 moves upward so that the first spring 207 contracts. At the same time, the limiting rod 502 is no longer engaged with the limiting groove 503. At this time, the slider 302 slides to the left. When the slider 302 slides, it moves more smoothly through the guide column 501. The slider 302 will drive the installation plate 303 and the fixing plate 305 to move. When it moves to a certain position, the pulling plate 506 is released, so that the limiting rod 502 is engaged with the other limiting groove 503 under the action of the second spring 504, and the front slider 302 is fixed. The limiting rod 502 is engaged with the guide column 501 in the front to fix the slider 302 to prevent the slider 302 from sliding freely, and then the first screw rod 304 is rotated, and the first screw rod 304 is threadedly matched with the mounting plate 303 when rotating, driving the fixing plate 305 to move to the left, and the guide plate 306 and the mounting plate 303 slide when the fixing plate 305 moves to the left. The setting of the guide plate 306 makes the fixing plate 305 move more smoothly. At the same time, the fixing plate 305 fixes the battery cover, and the position of the fixing plate 305 is adjusted by the slider 302, and then the fixing plate 305 is threadedly driven by the first screw rod 304 to fix the battery cover. When assembling battery covers of different lengths, it is convenient to quickly adjust the position of the fixing plate 305, which can improve the fixing efficiency of the battery cover.

[0046] When the parts on the back of the battery cover need to be assembled, the pull rod 208 is pulled to the left, and the pull rod 208 drives the two blocking rods 204 to slide to the left. When the blocking rod 204 slides, the connecting plate 206 moves to the left. When the connecting plate 206 moves to the left, the first spring 207 contracts. At the same time, the blocking rod 204 no longer resists the fixed block 205. Then, the installation frame 301 can be rotated to make the installation frame 301 drive the two rotating shafts 202 to rotate. When the rotating shaft 202 rotates, it drives the fixed block 205 to rotate. When the fixing block 205 rotates 180 degrees, the pull rod 208 is released, so that the blocking rod 204 slides to the right under the action of the first spring 207. At this time, the blocking rod 204 blocks and limits the fixing block 205, which is convenient for fixing the rotating shaft 202 to prevent the rotating shaft 202 from rotating. The rotating shaft 202 drives the mounting frame 301 to rotate, which is convenient for turning over the battery cover and assembling the components on the back of the battery cover, avoiding the need to disassemble the battery cover for secondary fixing, thereby improving the operation efficiency;

[0047] When it is necessary to fix battery covers of different widths, the first support rod 307 slides with the installation frame 301, and the first support rod 307 slides with the guide rod 401. The setting of the guide rod 401 makes the first support rod 307 move more smoothly. When the first support rod 307 slides to a certain position, by turning the knob 404, the thread drives the connecting block 403 to slide downward when the knob 404 is turned, so that the connecting block 403 drives the rubber pad 402 to move downward, so that the rubber pad 402 and the guide rod 401 are pressed tightly. The rubber pad 402 and the guide rod 401 are pressed tightly by the thread of the knob 404, which is convenient for fixing the first support rod 307 after sliding. The first support rod 307 and the installation frame 301 are slidably matched, so that the position of the first support rod 307 is adjusted according to the width of the battery cover, so that the first support rod 307 cooperates with the second support rod 308 to place battery covers of different widths;

[0048] When the base 1 is installed with the mounting hole of the workbench, the mounting column 602 is adjusted according to the position of the mounting hole. During adjustment, the adjusting plate 609 drives the adjusting block 601 to slide. When the adjusting block 601 slides, the mounting column 602 is driven to move. The mounting column 602 will slide with the fixing rod 606. When the mounting column 602 moves to a certain position, the two mounting columns 602 are plugged into the mounting holes on the workbench, and then the hexagonal wrench is inserted into the hexagonal groove at the end of the second screw rod 608. The second screw rod 608 is rotated, and the second screw rod 608 thread drives the slide plate 607 to slide. When the slide plate 607 slides, it drives the fixed rod 606 to move forward. When the fixed rod 606 moves forward, it drives the connecting rod 604 to move forward through the guide block 605. When the connecting rod 604 moves forward, it drives the mounting block 603 to be pressed against the workbench. When the second screw rod 608 rotates, the two mounting blocks 603 are simultaneously driven by threads to be pressed against the workbench. When installing the base 1 and the workbench, the installation efficiency is improved. At the same time, the position of the mounting column 602 can be adjusted, which is convenient for adjusting the position of the mounting column 602 according to the position of the reserved mounting hole on the workbench, thereby improving flexibility.
