A pull rod is movably inserted into the front outer surface of the limiting seat 9, and the pull rod is located outside the limiting seat 9. The cam 11 is fixedly connected to the upper end of the pull rod 12, and a spring 11 is fixedly connected between the pull rod 12 and the limit seat 9. The spring 11 is sleeved on the outer surface of the pull rod, and the other side of the pull rod away from the pull disc 12 is fixedly connected to the limit block. Specifically, the center of materials such as steel and bracket is placed with the center of the top of the bottom plate 1. After placement, pull the limit rod 7, the limit rod 7 drives the connecting plate 6 to pull one side of the binding belt 5 out, causing the rotating shaft to rotate and spit out the binding belt 5. Under the cooperation of the ratchet 22 and the pawl 23, the binding belt 5 is prevented from being retracted, and the binding belt 5 is passed around the surface of the bracket. Then, the pull rod on one side is pulled to deform the spring 11, and one end of the limit rod 7 is inserted into the slot 10, and the force applied to the pull rod is stopped, so that the elastic force of the spring 11 drives the pull rod to reset, so that the limit block at one end of the pull rod is inserted into the limit groove 8, limiting the limit rod 7, thereby limiting the limit rod 7, and limiting the bracket through the binding belt 5, increasing the stability of the bracket on the bottom plate 1.

[0024] The outer surface of the top of the two threaded blocks 14 are fixedly connected to the cross plate 15, and the outer surface of the top of the cross plate 15 is fixedly connected to three sliders. The outer surfaces of the tops of the three sliders are fixedly connected to the fixing plate 16. The outer surface of the fixing plate 16 is provided with an empty groove 17. Specifically, when bundling the bracket, the limit rod 7 and the connecting plate 6 are passed through the empty groove 17 of the fixing plate 16, so that the binding belt 5 is passed through the empty groove 17. The second knob is turned, and the second knob drives the positive and negative screw rods 13 to rotate, and the positive and negative screw rods 13 drive the two threaded blocks 14 to move, so that the two fixing plates 16 move, so that the fixing plates 16 move to both sides of the plate, so that the binding belts 5 on both sides of the plate are as close to the bottom plate 1 as possible, thereby increasing the stability during bundling.

[0025] In this embodiment, the left and right sides of the bottom outer surface of the base plate 1 are fixedly connected with inserts 18, and the front ends of the top outer surface of the base plate 1 are provided with first side panels 19. The bottom outer surface of the first side panel 19 is fixedly connected with two pins, and the four pins are respectively movably connected to the inside of the four inserts 18. Specifically, the first side panel 19 is installed by inserting the inserts 18 into the pins, and the front and rear sides of the bricks are limited when transporting materials such as bricks.

[0026] In this embodiment, sockets 20 are fixedly connected to the left and right sides of the bottom outer surface of the base plate 1, and a second side panel 21 is movably inserted inside the socket 20. The forward and reverse screw rods 13 are rotatably connected to the outer surface of the right socket 20, and the forward and reverse screw rods 13 are rotatably passed through the left socket 20. Specifically, the second side panel 21 is inserted into the socket 20, and the second side panel 21 is spliced ​​to limit the left and right sides of the bricks when transporting materials such as bricks.

[0027] In this embodiment, a ratchet 22 is fixedly sleeved at one end of the rotating shaft located outside the fixing seat 2, and a pawl 23 is rotatably connected to the outer surface of the fixing seat 2. The pawl 23 engages with the ratchet 22. Specifically, the pawl 23 cooperates with the ratchet 22 to prevent the rotating shaft from reversing, and by pulling the pawl 23, the pawl 23 is disengaged from the teeth of the ratchet 22, so that the ratchet 22 is released from the limit.

[0028] In this embodiment, three sliding grooves are provided on the outer surface of the base plate 1, and the three sliders are respectively slidably connected to the inside of the three sliding grooves. Specifically, when the forward and reverse screw rods 13 rotate, the threaded block 14 is driven to move the slider inside the sliding groove, and the sliding groove provides a channel for the movement of the slider.

[0029] In this embodiment, the four corners of the base plate 1 are fixedly connected with fixing buckles. Specifically, by providing the fixing buckles and connecting them with the lifting ropes, the base plate 1 can be lifted and transported as a whole.

[0030] Working principle: When the utility model is in use, when it is necessary to transport long materials such as steel and brackets, the first side plate 19 and the second side plate 21 are disassembled, and the center of the steel and bracket and other materials are placed at the center of the top of the bottom plate 1. After placement, the limit rod 7 is pulled, and the limit rod 7 drives the connecting plate 6 to pull out one side of the binding belt 5, so that the rotating shaft rotates and spits out the binding belt 5. Under the cooperation of the ratchet 22 and the pawl 23, the binding belt 5 is prevented from being retracted, and the binding belt 5 is passed around the surface of the bracket, and then one side is pulled. The pull rod deforms the spring 11, inserts one end of the limit rod 7 into the slot 10, stops applying force to the pull rod, and allows the elastic force of the spring 11 to drive the pull rod to reset, so that the limit block at one end of the pull rod is inserted into the limit slot 8, limiting the limit rod 7, thereby limiting the limit rod 7, and limiting the bracket through the binding belt 5 to increase the stability of the bracket on the base plate 1, and then lift the base plate 1 as a whole for transportation, so as to avoid the internal bracket falling due to the shaking of the unloading platform during lifting, causing a safety hazard.

[0031] When bundling the bracket, the limiting rod 7 and the connecting plate 6 are passed through the empty slot 17 of the fixing plate 16, so that the binding belt 5 is passed through the empty slot 17, and the second knob is turned. The second knob drives the forward and reverse screw rods 13 to rotate, and the forward and reverse screw rods 13 drive the two threaded blocks 14 to move, so that the two fixing plates 16 move, so that the fixing plates 16 move to both sides of the plate, so that the binding belts 5 on both sides of the plate are as close to the bottom plate 1 as possible, thereby increasing the stability during bundling.

[0032] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
