Racks 403 are movably connected to both sides of the inside of the adjustment box 401, and the two racks 403 are meshed with the gear 402. When the gear 402 rotates, the two racks 403 can be pushed to move in opposite directions.

[0025] A protective plate 404 is fixedly mounted on one end of the two racks 403 , and the two racks 403 can push the two protective plates 404 to move in opposite directions.

[0026] The outer top surface of the regulating box 401 is provided with a plurality of limiting holes 407 , and the top surface of the gear 402 is fixedly connected with a rotating plate 405 , and when the staff rotates the rotating plate 405 , the gear 402 can be driven to rotate.

[0027] Two limiting bolts 406 are movably connected to one side of the rotating plate 405 . When the two limiting bolts 406 are inserted into the limiting holes 407 , the rotating plate 405 can be prevented from rotating.

[0028] A slide groove 408 is provided on the opposite side of the two protective plates 404, and a first slide rod 409 is fixedly installed inside the two slide grooves 408. The outer surfaces of the two first slide rods 409 are movably connected to two telescopic plates 410. The telescopic plates 410 can be telescoped, and when the two protective plates 404 move in opposite directions, the two telescopic plates 410 can be telescoped, and the two telescopic plates 410 can move along the two first slide rods 409, and then cooperate with the movement of the protective plates 404 to adjust the size of the limit frame 4. Multiple openings are provided on one side of the two protective plates 404.

[0029] like Figure 3 As shown, a movable frame 4101 is fixedly installed on one side of the top surface of the telescopic plate 410, and a movable plate 4102 is movably installed inside the movable frame 4101. A fixing bolt 4103 is movably connected to one side of the movable plate 4102. When the telescopic plate 410 is moved to a suitable position, the movable plate 4102 and the fixing bolt 4103 are rotated and inserted into the opening of the protective plate 404 to prevent the telescopic plate 410 from continuing to move.

[0030] like Figure 4As shown, two extension plates 501 are movably connected inside the material guide plate 5 , and the extension plates 501 can move inside the material guide plate 5 .

The staff pulls the connecting plate 504 to pull the plug rod 505 out of the adjustment hole 502 to move the extension plate 501, and loosens the connecting plate 504. Under the action of the spring 503, the plug rod 505 can be inserted into the adjustment hole 502 to prevent the extension plate 501 from continuing to move.

[0032] like Figure 5 As shown, a threaded rod 201 is movably installed on one side of the interior of the lifting box 2, and a second slide bar 202 is fixedly installed on the other side of the interior of the lifting box 2. Two moving blocks 203 are movably connected to the outer surface of the threaded rod 201, and the two moving blocks 203 are movably connected to the second slide bar 202.

[0034] It should be noted that the outer surface of the threaded rod 201 is provided with two opposite threaded grooves, and when the motor 206 drives the threaded rod 201 to rotate, it can drive the two moving blocks 203 to move in opposite directions, and then the two connecting rods 204 can drive the conveyor 3 to rise and fall, so as to transfer the bearing to the punching equipment at different heights.

[0035] The working principle of the utility model is as follows: the staff first places the device in a suitable position, and then starts the motor 206 to drive the threaded rod 201 to rotate, so that the two moving blocks 203 move in opposite directions to push the conveyor 3 to rise and fall, so as to adjust the height of the conveyor 3. After the adjustment is completed, the staff rotates the rotating plate 405 to make the gear 402 drive the two racks 403 to move, so that the two protective plates 404 move in opposite directions. After moving to the appropriate position, the limit bolt 406 is rotated to insert it into the limit hole 407, and the two telescopic plates 410 are moved. After moving, the fixing bolt 4103 is rotated to insert it into the opening of the protective plate 404 to adjust the size of the limit frame 4. After the adjustment is completed, the bearing can be placed in multiple limit frames 4 in turn, and the conveyor 3 is started for feeding.
