A fixed block 9 is fixed on the inner bottom wall of the bracket 1, a base 11 is inserted into the inner side of the top of the fixed block 9, and a blocking cylinder 10 is installed at the top of the base 11. A snap structure 12 for clamping and limiting the base 11 is provided in the fixed block 9, and a bottom plate 17 is provided under the bracket 1, and first telescopic rods 18 are installed at the four corners of the top of the bottom plate 17, and the output ends of the four first telescopic rods 18 are fixed to the bracket 1.

[0021] The effect achieved by the entire embodiment 1 is that the rotation of the two driving rollers 2 can drive the four sprockets 3 to rotate, thereby driving the two speed chain bodies 4 to perform transmission processing, and can perform transmission processing on the carrier 7 placed on the top thereof. After the carrier 7 is transmitted to the appropriate position, the blocking cylinder 10 blocks the carrier 7 so that the carrier 7 no longer moves. At this time, the product on the carrier 7 can be processed, and the blocking cylinder 10 can be quickly installed and removed by the operation of the snap structure 12. Compared with the traditional bolt installation and removal, this installation and removal is more efficient and more practical. Through the synchronous operation of the four first telescopic rods 18, the bracket 1 can be driven to rise and fall as a whole, and the height can be adjusted.

[0022] Example 2, as Figures 1-4 As shown, the snap-fit ​​structure 12 includes an inner cavity 1201 opened on the inner wall of the fixed block 9, a spring 1202 is fixed on the inner wall of the inner cavity 1201, a clamping column 1203 is fixed to one end of the spring 1202, and the end of the clamping column 1203 away from the spring 1202 passes through the inner cavity 1201 and is movably plugged into the base 11, a support plate 19 is provided below the bracket 1, a second telescopic rod 20 is installed on the top of the support plate 19, a rotating block 21 is fixed to the output end of the second telescopic rod 20, the top of the rotating block 21 is rotatably connected to the bracket 1, a second motor 22 is installed on the inner bottom wall of the rotating block 21, and the output end of the second motor 22 is fixed to the bracket 1 , an opening 23 matching the support plate 19 is opened in the bottom plate 17, and connecting plates 13 are fixed at both ends of the outer wall of the card column 1203. One end of the two connecting plates 13 passes through the fixed block 9 and is jointly fixed with a pull ring 14. One end of the fixed block 9 is provided with a movable groove 15 matching the connecting plate 13, and one end of the base 11 is provided with a card hole 16 matching the card column 1203. A fixing frame 5 is fixed on the outer wall of the bracket 1, and a first motor 6 is installed on the end of the fixing frame 5 facing the bracket 1. The output end of the first motor 6 passes through one side of the bracket 1 and is fixed to one of the driving rollers 2. Baffles 8 are fixed on both sides of the top of the bracket 1.

[0023] The effect achieved by the entire embodiment 2 is that when it is necessary to disassemble the blocking cylinder 10, it is only necessary to pull the pull ring 14 to drive the clamping column 1203 to disengage from the clamping hole 16 opened at one end of the base 11. At this time, the base 11 is no longer limited by the clamping column 1203, and the user can directly move up to remove the blocking cylinder 10. When installing, it is only necessary to pull the pull ring 14 to drive the clamping column 1203 to retract into the inner cavity 1201, insert the base 11 into the fixed block 9, and release the pull ring 14. At this time, the clamping column 1203 enters the bottom under the reset thrust of the spring 1202. The card hole 16 opened at one end of the seat 11 can achieve the effect of card connection and limiting. This method is simple to operate and has higher installation and disassembly efficiency. Through the operation of the second telescopic rod 20, the support plate 19 can replace the bottom plate 17 to support the entire bracket 1. At this time, through the operation of the second motor 22, the entire bracket 1 can be driven to rotate to achieve the effect of angle adjustment. Through the operation of the first motor 6, one of the driving rollers 2 can be driven to rotate, and through the cooperation of the other driving roller 2 and the four sprockets 3, the speed chain body 4 is driven to perform transmission processing.

[0024] Working principle: When the device is in use, the operation of the first motor 6 can drive one of the driving rollers 2 to rotate, and through the cooperation of the other driving roller 2 and the four sprockets 3, the speed chain body 4 is driven to perform transmission processing, and the carrier 7 placed on the top thereof can be transmitted. After the carrier 7 is transmitted to the appropriate position, the carrier 7 is blocked by the blocking cylinder 10 so that the carrier 7 no longer moves. At this time, the product on the carrier 7 can be processed. When it is necessary to disassemble the blocking cylinder 10, it is only necessary to pull the pull ring 14 to drive the clamping column 1203 to disengage from the clamping hole 16 opened at one end of the base 11. At this time, the base 11 is no longer limited by the clamping column 1203, and the user can directly move up to remove the blocking cylinder 10. During installation, It is only necessary to pull the pull ring 14 to drive the card column 1203 to retract into the inner cavity 1201, insert the base 11 into the fixed block 9, loosen the pull ring 14, and allow the card column 1203 to enter the card hole 16 opened at one end of the base 11 under the reset thrust of the spring 1202, so as to achieve the effect of card connection and limitation. This method is simple to operate and has higher installation and disassembly efficiency. In addition, the device can drive the entire bracket 1 to rise and fall and adjust the height through the synchronous operation of the four first telescopic rods 18. Through the operation of the second telescopic rod 20, the support plate 19 can replace the bottom plate 17 to support the entire bracket 1. At this time, through the operation of the second motor 22, the entire bracket 1 can be driven to rotate to achieve the effect of angle adjustment.
