In this embodiment, a plurality of locking pin holes are provided on the front fixing frame 5 along the height direction, and the locking pin passes through any locking pin hole and is inserted into the socket on the lifting hinge rod 501 to fix it. After the locking pin is pulled out, the lifting hinge rod 501 can cooperate with the lifting to adjust the height.

[0042] like Figures 7-8 As shown, in another embodiment of the present invention, arc-shaped pressure plates 12 of appropriate sizes can be arranged inside the arc-shaped recesses of the left clamp block 3 and the right clamp block 4 according to the conditions of the device body 17 to further meet the clamping requirements of the device bodies 17 of different specifications and sizes. When the present embodiment is working, the device body 17 is clamped by the arc-shaped pressure plates 12 on both sides. In the present embodiment, adjustment mounting plates 14 and adjustment bolts 13 are provided on both sides of the left clamp block 3 and the right clamp block 4, and the adjustment bolts 13 are threadedly inserted on the corresponding adjustment mounting plates 14, and the head ends of the adjustment bolts 13 are threadedly connected to the corresponding arc-shaped pressure plates 12. In the present embodiment, on the one hand, the spacing between the arc-shaped pressure plates 12 on both sides can be changed by screwing the adjustment bolts 13 to better match the device body 17, and on the other hand, it is also convenient to remove the arc-shaped pressure plates 12 from the adjustment bolts 13 to replace the arc-shaped pressure plates 12 of appropriate specifications, which is more flexible to use, and the installation method of the left clamp block 3 and the right clamp block 4 in the present embodiment can be the same as Figure 1The embodiment in FIG. 1 is the same, that is, the left clamp block 3 and the right clamp block 4 can also be replaced according to actual needs, which further improves the scope of application of the present invention. In addition, the arc-shaped pressing plate 12 used in this embodiment is also more convenient for tying the body 17, especially when the opening of the body 17 needs to be fine-tuned. At this time, it is not necessary to adjust the clamp block driving device 6 forward or backward, which is often difficult to control the movement amount. At this time, the operator can adjust the spacing of the arc-shaped pressing plate 12 by screwing each adjustment bolt 13, so that the movement amount of the arc-shaped pressing plate 12 can be better adjusted according to the tying needs.

[0043] In order to avoid damage to the device body 17, rubber protective pads can be provided on the arc-shaped recesses of the left clamping block 3 and the right clamping block 4 as needed, and rubber protective pads can also be provided on the arc-shaped pressure plate 12 as needed.

[0044] The working principle of the present invention is:

[0045] The present invention comprises the following steps when used:

[0046] Step 1: The operator flips the rotating pressure plate 2 open, and selects the left clamp block 3 and the right clamp block 4 of appropriate specifications according to the specifications of the device body 17 to be tied, and then places the selected left clamp block 3 and the right clamp block 4 on the lower support plate 8, wherein it is necessary to ensure that the positioning sliders 15 on the lower sides of the left clamp block 3 and the right clamp block 4 cooperate with the clamp block positioning grooves 801 on the lower support plate 8, so that while ensuring the accurate positioning of the clamp blocks, it also realizes the sliding connection between the clamp blocks and the lower support plate 8. After the left clamp block 3 and the right clamp block 4 are placed, the end of the piston rod 601 of the clamp block driving device 6 is fixedly connected to the clamp block shaft at the rear end of the right clamp block 4 by the locking bolt 6011.

[0047] Step 2: The operator pushes the supporting lifting trolley 9 to move to the bottom of the device body 17 to be tied. At this time, the two ends of the device body 17 can be supported by the brackets, and then the operator operates the lifting support plate 901 of the supporting lifting trolley 9 to rise and adjust so that the device body 17 enters between the left clamping block 3 and the right clamping block 4 and is supported by the lower support plate 8.

[0048] Step three: The operator flips and snaps the rotating pressure plate 2 together, wherein the upper pressure plate 201 of the rotating pressure plate 2 is pressed on the upper sides of the left clamp block 3 and the right clamp block 4, and the left clamp block 3 is against the side limit plate 202, and then the fixing pin 1 is inserted into the upper pressure plate 201, and the fixing pin 1 passes through the plug ring 203 on the outside of the side limit plate 202 and is inserted into the socket 802 on the lower support plate 8.

[0049] Step 4: The operator starts the clamping block driving device 6 to move the right clamping block 4 toward the left clamping block 3. Fig. 9As shown, the U-shaped opening of the device body 17 is slowly clamped with the cooperation of the left clamp block 3 and the right clamp block 4. After the device body 17 is clamped in place, the right clamp block 4 stops moving and maintains the current position of the device body 17. Then the operator ties the two legs of the device body 17 together through the device body drawstring 16.

[0050] The present invention controls the clamping block driving device 6 to drive the right clamping block 4 to slowly move and clamp the device body 17, and the clamping force can be controlled by the clamping block driving device 6, thereby avoiding the disadvantage of controlling the force only by personal experience in the prior art. At the same time, the present invention can select the left clamping block 3 and the right clamping block 4 (or the arc-shaped pressure plate 12) with suitable arc-shaped recess specifications according to the size specifications of the device body 17, and protective pads can be provided on the arc-shaped recesses (or the arc-shaped pressure plates 12) of the left clamping block 3 and the right clamping block 4 as needed, thereby ensuring that the surface of the device body 17 will not be damaged during the tightening operation.

[0051] The present invention is flexible to use and has a wide range of applications, including Figure 1 and Figure 6 As shown, in one embodiment of the present invention, the left clamp block 3 and the right clamp block 4 of appropriate specifications can be selected according to the specifications of the device body, wherein the heights of different clamp blocks and the sizes of the arc-shaped recesses in the middle are different. In order to meet the positioning requirements of clamp blocks of different heights, the side limit plate 202 in this embodiment adopts a telescopic plate structure so that the length can be flexibly adjusted according to the actual clamp block height, thereby ensuring that after the rotating pressure plate 2 is buckled, the side limit plate 202 can ensure that the left clamp block 3 is limited. In this embodiment, the upper end of the front fixed frame 5 is provided with a lifting hinge rod 501, and one end of the upper pressure plate 201 is hinged to the upper end of the lifting hinge rod 501. The lifting hinge rod 501 can cooperate with the lifting to adjust the height, so as to ensure that after the rotating pressure plate 2 is buckled, its upper pressure plate 201 can be horizontally pressed on the upper side of the left clamp block 3 and the right clamp block 4.

[0052] like Figures 7-8 As shown, in another embodiment of the present invention, an arc-shaped pressure plate 12 of appropriate size can be arranged inside the arc-shaped recess of the left clamp block 3 and the right clamp block 4 according to the condition of the device body 17, so as to further meet the clamping requirements of the device body 17 of different specifications and sizes. In addition, this embodiment is also more convenient for binding the device body 17, especially when it is necessary to fine-tune the opening of the device body 17. At this time, it is not necessary to control the clamp block driving device 6 to move forward or backward for adjustment, which often makes it difficult to control the movement amount. At this time, the operator can adjust the spacing of the arc-shaped pressure plate 12 by screwing each adjusting bolt 13, so as to better adjust the movement amount of the arc-shaped pressure plate 12 according to the binding needs. In addition, the installation method of the left clamp block 3 and the right clamp block 4 of this embodiment can also be the same as Figure 1 The same as the embodiment in, so the use is more flexible, further improving the scope of application of the present invention.
