At the same time, in order to adjust the adjusting cross bar 15 The bottom of the rotating block 12 is provided with a screw hole, and a screw rod is transferred into the screw hole. The top of the screw rod is pressed against the adjusting cross bar 15 to limit the adjusting cross bar 15. The surface of the positioning slot plate 9 is provided with an arc-shaped arc opening 14. The adjusting cross bar 15 passes through the arc opening 14 and extends to the other side of the positioning slot plate 9. The arc opening 14 provides space for the rotation of the adjusting cross bar 15. By driving the driving motor 10, the rotating cylinder 11 can drive the rotating block 12, and then the rotating block 12 drives the adjusting cross bar 15. The rod 15 rotates, and a crossbar front column 16 is fixed at the front end of the adjusting crossbar 15.

One end of the positive and negative screw rods 20 is connected to the bottom of the positioning slot plate 9 through a support, and the other end is connected to the output end of the screw drive motor 21. Through the drive of the screw drive motor 21, the two movable sleeves connected to the positive and negative screw rods 20 drag the two groups of synchronous connecting rods 19 to move, thereby dragging the cross bar sleeve 17 and the cross bar front column 16 to move, thereby changing the position of the adjustment cross bar 15 in the groove of the cross hole 13, and then adjusting the spacing of the oppositely distributed adjustment clamps 22 to change the clamping distance.

[0040] An assembly screw hole 26 is provided on the surface of the lower sleeve plate 18, and an assembly screw rod portion 27 is threadedly connected to the inner thread of the assembly screw hole 26. An assembly through-hole portion 28 is provided on the surface of the lower sleeve plate 18 and is located above the assembly screw hole 26. An assembly through-rod portion 29 is slidably penetrated in the assembly through-hole portion 28, and a side pressure block portion 30 is fixed to the front end of the assembly through-rod portion 29. The surface of the side pressure block part 30 is provided with a hole groove, and a turntable cylinder 31 is rotatably connected in the hole groove. A spring part 32 is installed on the inner side of the turntable cylinder 31. The front end of the spring part 32 is installed on the movable sleeve part 33. The movable sleeve part 33 slides along the hole groove, and the front end of the assembly screw part 27 is screwed into the positioning baffle part 25, and the assembly through-rod part 29 is inserted into the assembly through-hole part 28. With the rotation of the assembly screw part 27, the position of the side pressure block part 30 can be adjusted. The installation position of the side pressure block part 30 is located between the two groups of adjustment clamping plates 22. The positioning cylinder part 23 supports the bottom of the product, so that the side pressure block part 30 can support the product. A certain degree of pressure is applied to the side to further improve stability, and due to the existence of the turntable barrel 31, the side pressure block portion 30 does not need to rotate when the assembly screw portion 27 rotates, so that the slope of the side pressure block portion 30 is always facing upward, and the spring portion 32 exists between the turntable barrel 31 and the movable sleeve portion 33, and one end of the movable sleeve portion 33 slides into the matching hole in the turntable barrel 31, and at the same time, the hole groove of the side pressure block portion 30 also has a hole that allows the movable sleeve portion 33 to move radially. Therefore, through the elastic action of the spring portion 32, the movable sleeve portion 33 and the side pressure block portion 30 have the effect of clamping the side of the product.
