[0002] When constructing a construction site, it is necessary to build a rebar cage, which requires the use of a rebar tying machine to tie different types of rebar. The rebar tying machine is 3-4 times more efficient than manual tying of rebar. When tying rebar, the working jaws clamp the rebar, the trigger is pressed, and the power unit drives two wire feeding gears to rotate, supplying tying wire to the working jaws. The tying wire at the point where the rebar is to be tied forms a U-shape. Then the tying device hooks the U-shaped tying wire, and the power unit drives it to rotate several times to tightly tie the rebar.

[0003] Meanwhile, a rebar tying machine with application number CN202222613821.5 includes a rebar tying machine, a wire spool, and a wire cutting box. The wire spool is provided on one side of the rebar tying machine, and the wire cutting box is fixedly installed on one side of the outer wall of the rebar tying machine. A cutting mechanism is provided on one side of the top outer wall of the rebar tying machine to cut off the ends of the tied rebar wires and facilitate the replacement of the cutting head.

[0004] However, the following problems were found in the implementation of the relevant technology: the handle of the rebar tying machine is set to a fixed width, which makes it unsuitable for workers with different grip sizes, reduces the stability of workers holding the rebar for tying, and if it falls off the hand, it will not only damage the tying machine but also affect the tying efficiency. Utility Model Content

[0005] To address the problems mentioned in the background art, this utility model provides an anti-drop fastening strap, which has the advantage of easily adjusting the width of the handle to accommodate different grip sizes of workers.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an anti-detachment fastening strapping device, comprising a handle, a strapping device body connected to the top of the handle, a first gripping block engaged with the surface of the handle, a second gripping block engaged with the surface of the handle, a locking component provided on the first gripping block, and a limiting component provided on the second gripping block.

[0007] Preferably, the engaging assembly includes four engaging blocks and four sliding grooves. The four engaging blocks are all disposed on the surface of the first gripping block, and the inner sides of the four engaging blocks are provided with sliding grooves. The inner sides of the four sliding grooves are all connected to a first magnetic sheet.

[0008] Preferably, the limiting component includes sixteen through slots, four fixing rods, four first slots, and four second slots. Eight of the through slots are located on the inner side of the top of the second grip, and the other eight are located on the inner side of the bottom of the second grip. A retraction spring is connected to the inner side of each through slot. A convex plate is connected to one end of every four retraction springs. The four fixing rods are respectively disposed on the surface of the four convex plates. A second magnetic sheet is connected to one end of each of the four fixing rods. Two of the first slots are located on the inner side of the top of the second grip, and the other two are located on the inner side of the bottom of the second grip. The four second slots are located on the inner side of the second grip.

[0020] Furthermore, the limiting component 3 includes sixteen through slots 31, four fixing rods 34, four first slots 36, and four second slots 37. Eight through slots 31 are all located on the inner side of the top of the second grip block 6, and the other eight through slots 31 are all located on the inner side of the bottom of the second grip block 6. Each through slot 31 is connected to a retraction spring 32 on its inner side. One end of every four retraction springs 32 is connected to a convex plate 33. The four fixing rods 34 are respectively disposed on the surface of the four convex plates 33. One end of each of the four fixing rods 34 is connected to a second magnetic sheet 35. Two of the first slots 36 are located on the inner side of the top of the second grip block 6, and the other two first slots 36 are located on the inner side of the bottom of the second grip block 6. The four second slots 37 are all located on the inner side of the second grip block 6.

[0021] Furthermore, the surfaces of the four second magnetic pieces 35 are respectively slidably attached to the inner sides of the four first card slots 36.

[0022] It is worth noting that the four first slots 36 are connected to the four slides 22 respectively, and the four first slots 36 are connected to the four second slots 37 respectively.

[0023] It is worth noting that the surface of the card block 21 is in contact with the surface of the second card slot 37.

[0024] It is worth mentioning that the surfaces of the four convex discs 33 are all in contact with the surface of the second grip block 6.

[0025] It is worth emphasizing that the four second magnetic sheets 35 are magnetically attracted to the four first magnetic sheets 23 respectively.

[0026] The binding device body 4, the first magnetic plate 23, and the second magnetic plate 35 are existing technologies and will not be described in detail.

The "front, back, left, and right" views of this device are... Figure 1 The direction shown in the diagram is the reference.

[0027] Working principle: First, the operator chooses whether to install the first grip block 5 and the second grip block 6 based on the grip strength. If the operator has a large grip strength and needs to install the first grip block 5 and the second grip block 6, the second grip block 6 is first engaged and fitted onto the curvature of the handle 1 surface. Then, under the elastic connection of the corresponding retraction spring 32, all four protrusions 33 are pulled outwards. The four second magnetic pieces 35 will then slide inside the corresponding first slot 36 and slide groove 22. After the surfaces of the four second magnetic pieces 35 are separated from the corresponding slide groove 22 and are only located in the four first slots 36, the four locking blocks 21 are respectively engaged into the four second slots 37, and then the corresponding protrusions 33 are released. Then, the four protrusions 33, the four fixing rods 34, and the four second magnetic pieces 35 will slide outwards. The magnetic sheet 35 will retract and reset under the contraction action of the corresponding retraction spring 32. At this time, the four second magnetic sheets 35 and the four first magnetic sheets 23 will be magnetically attracted to each other, thereby limiting the locking block 21 inside the second locking slot 37. This allows the first grip block 5 and the second grip block 6 to be engaged and connected, thus installing the first grip block 5 and the second grip block 6 on the surface of the handle 1 to adapt to the grip required by the construction personnel, thereby meeting the grip needs of different workers and preventing the grip from falling off. This improves the overall anti-fall-off performance of the binding device body 4 during use. Furthermore, by improving the grip comfort, it helps to improve the binding efficiency and tightness of the construction workers. It should also be noted that the first grip block 5 and the second grip block 6 can be set with multiple thicknesses, so multiple sets can be replaced as needed.
