[0031] Specifically, the outer shell 1 is used to connect and protect internal parts, and its top is for placing removed parts. The motor 2 is used to drive the gear 1 3 to rotate. The gear 1 3 and the gear 2 5 are both bevel gears. Two slide grooves are opened inside the turntable 4 to enable the two levers 6 to slide synchronously in opposite directions inside it. The limit plate 7 is fixed on the top of the lever 6 and moves synchronously with the lever 6 to adjust the distance between the two limit plates 7. The sliding rod 8 is fixed on the left and right sides of the bottom of the limit plate 7 to limit the movement direction of the limit plate 7 to ensure that the limit plate 7 can only move forward and backward and will not move around. The back plate 9 is used to block the parts.

[0032] Reference Figure 1 - Figure 3 The expansion component includes a front plate 10 and a fixing plate 12. The bottom of the front plate 10 is rotatably connected to the left side of the shell 1. The front and rear sides of the bottom of the front plate 10 are fixedly connected to a fixing plate 11. The top of the fixing plate 12 is fixedly connected to the inner top wall of the shell 1. A pull rod 13 is slidably connected inside the fixing plate 12. A baffle 14 is fixedly connected to the outside of the pull rod 13. A spring 15 is arranged between the baffle 14 and the fixing plate 12. Two grooves 16 are provided on the left side of the pull rod 13. The pull rod 13 and the fixing plate 11 are engaged with each other. The outside of the fixing plate 11 is rotatably connected to the inside of the left side of the shell 1. The right side of the front plate 10 is slidably connected to the left side of the limit plate 7. The outside of the pull rod 13 is slidably connected to the inside of the shell 1. The spring 15 is internally sleeved on the outside of the pull rod 13. One end of the spring 15 is fixedly connected to the rear side of the fixing plate 12, and the other end of the spring 15 is fixedly connected to the front side of the baffle 14. The outer periphery of the fixing plate 11 is slidably connected to the inside of the groove 16.

[0033] Specifically, the front plate 10 is used to expand the space of the outer shell 1 or to completely lower the front plate 10 to directly contact the ground, so as to facilitate pushing overweight parts onto the outer shell 1 from the ground. The fixed plate 11 is used to limit the deflection angle of the front plate 10. There are many semicircular grooves on its surface for engaging with the pull rod 13 to achieve fixation. The fixing plate 12 is used to connect and support the pull rod 13. The pull rod 13 is for engaging with the fixed plate 11. The groove 16 is used to unlock the fixed plate 11 and allow it to rotate. The baffle 14 is used to compress the spring 15, and the spring 15 is for resetting the pull rod 13.

[0034] Working principle: When using this device, when the size of the disassembled parts is too long, it is necessary to open the front plate 10 to increase the area of ​​the shell 1. First, pull the pull rod 13 to keep the groove 16 and the fixed plate 11 on the same horizontal line. At this time, the fixed plate 11 is unlocked, and the front plate 10 can be rotated at will to keep the front plate 10 level with the shell 1. At this time, release the pull rod 13, and under the action of the fixing plate 12, the spring 15 pushes the baffle 14 to drive the pull rod 13 to move backward, so that the groove 16 and the fixed plate 11 are staggered to achieve fixation, and then the parts are placed on the shell 1 and transported away. Before transporting them away, the parts need to be clamped and fixed to avoid sliding and falling from the left side and causing bumps. First, control the motor 2 to rotate, and the gear 1 3 drives the gear 2 5 to make the turntable 4 start to rotate. The lever 6 starts to move to the middle under the rotation of the turntable 4, and the limit plate 7 moves synchronously with the lever 6 under the limit of the slide bar 8 to clamp the parts to prevent them from falling off.
