Detailed Implementation

[0027] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0028] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0029] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0030] For an example, please refer to... Figures 1-4A rebar binding device includes a wire hook body 1, one end of which is connected to a hook tip 101. A protective tube 2 and an elastic ring 201 are fitted on the outer surface of the hook tip 101. The elastic ring 201 is fixedly installed on the protective tube 2. The protective tube 2 is used to protect the hook tip 101. The protective tube 2 is limited to the hook tip 101 by the elasticity of the elastic ring 201. When carried in a non-use state, the protective tube 2 can protect the hook tip 101, reducing the risk of the hook tip 101 accidentally injuring the user or other items. The elastic ring 201 is made of elastic rubber. When the elastic ring 201 is fitted on the outer surface of the hook tip 101, the hook tip 101 expands the elastic ring 201, causing the elastic ring 201 to deform and generate force to limit it to the hook tip 101.

[0031] Furthermore, a connecting groove 103 is provided at the end of the wire hook body 1 away from the hook tip 101. A connecting shaft 104 is connected between the connecting groove 103 and the wire hook body 1. A connecting rod 102 is sleeved on the outer surface of the connecting shaft 104. The connecting shaft 104 is used to connect the wire hook body 1 and the connecting rod 102 together. The wire hook body 1 can rotate around the connecting shaft 104 to adjust the angle between the wire hook body 1 and the connecting rod 102.

[0032] An arc-shaped opening 108 is provided on the connecting rod 102. An annular plate 106 is slidably connected to the inner wall of the arc-shaped opening 108. The annular plate 106 is fixedly connected to the wire hook body 1. Two second through holes 107 are provided on the annular plate 106. A first hand-tightening bolt 109 is threadedly connected to the connecting rod 102. One end of the first hand-tightening bolt 109 is inserted into the arc-shaped opening 108 and plugged into one of the second through holes 107. The position of the annular plate 106 can be fixed by the plugging of the first hand-tightening bolt 109 into the second through hole 107, thereby fixing the position between the wire hook body 1 and the connecting rod 102.

[0033] Furthermore, a first protective shell 301 is sleeved on the outer surface of the connecting rod 102 through a bearing. A geared motor 302 is installed inside the first protective shell 301, and the output shaft of the geared motor 302 is connected to the connecting rod 102 through a coupling. The geared motor 302 can drive the connecting rod 102, the wire-binding hook body 1, and the hook tip 101 to rotate in order to perform the wire-binding operation.

[0034] Furthermore, a limiting tube 316 is fixedly connected to one end of the first protective shell 301 near the main body 1 of the wire hook. The outer surface of the limiting tube 316 is connected to the connecting rod 102 through a bearing. A first through hole 105 is provided on the connecting rod 102, and a second threaded hole 317 corresponding to the position of the first through hole 105 is provided on the limiting tube 316.

[0035] Furthermore, a partition 303 is fixedly installed inside the first protective shell 301. A first threaded hole 304 is provided on the partition 303. A second protective shell 308 is provided on the first protective shell 301. A fixing bolt 310 is provided on the second protective shell 308, and the fixing bolt 310 is connected to the first threaded hole 304. A threaded ring 309 is connected to the end of the second protective shell 308 away from the wire hook body 1. The second protective shell 308 can be fixed to the partition 303 by the cooperation of the fixing bolt 310 and the first threaded hole 304.

[0036] Furthermore, a negative electrode spring 305 is installed on the side of the partition 303 away from the geared motor 302. A rechargeable battery 306 is placed on the side of the negative electrode spring 305 away from the partition 303. A positive electrode metal sheet 307 is placed on the side of the rechargeable battery 306 away from the negative electrode spring 305. A threaded ring 309 is threadedly connected to a bolt plug 311 that limits the position of the positive electrode metal sheet 307. By limiting the position of the positive electrode metal sheet 307 by the bolt plug 311, the positive electrode metal sheet 307 can be kept in contact with the rechargeable battery 306. After unscrewing the receiving groove 312, the positive electrode metal sheet 307 and the rechargeable battery 306 can be removed to replace the rechargeable battery 306.

[0037] Furthermore, the bolt plug 311 has a receiving groove 312, which is used to accommodate the protective tube 2. That is, when in use, the protective tube 2 is removed and inserted into the receiving groove 312. The protective tube 2 is confined in the receiving groove 312 under the friction of the elastic ring 201. The inner diameter of the elastic ring 201 in its natural state is smaller than the maximum outer diameter of the hook tip 101, so that it is fixed to the hook tip 101 by generating elastic pressure through radial expansion. The outer diameter of the elastic ring 201 in its natural state is larger than the inner diameter of the receiving groove 312.

[0038] Furthermore, a wiring groove 313 is provided on the inner wall of the first protective shell 301 for wiring; a switch button 315 is installed on the first protective shell 301, which is connected between the geared motor 302 and the positive metal plate 307, and the positive and negative springs 305 are connected to the geared motor 302. The above connection is made through wires. When the switch button 315 is pressed, the geared motor 302 is energized and works; when it is released, the geared motor 302 stops working.

[0039] Furthermore, a protective sleeve 318 is fitted on the outer surface of the threaded ring 309 through a bearing. A fourth through hole 319 is provided on the protective sleeve 318, and the position of the fourth through hole 319 corresponds to the position of the fixing bolt 310. The fourth through hole 319 is provided to prevent the protective sleeve 318 from affecting the operation of the fixing bolt 310.

[0040] The first protective shell 301 has a third through hole 314, and the protective sleeve 318 is threaded with a second hand-tightening bolt 320. One end of the second hand-tightening bolt 320 is inserted into the third through hole 314. The insertion of the second hand-tightening bolt 320 into the third through hole 314 can fix the protective sleeve 318, so that the protective sleeve 318 will not rotate between the first protective shell 301 and the second protective shell 308. After the second hand-tightening bolt 320 is separated from the third through hole 314, the protective sleeve 318 can rotate.

[0041] In use, pull the protective tube 2 to separate it from the hook tip 101, then insert the elastic ring 201 into the receiving groove 312, i.e. Figure 5 As shown, during the binding process, pressing the switch button 315 powers on the reduction motor 302, which drives the connecting rod 102 to rotate. The connecting rod 102 drives the binding hook body 1 and hook tip 101 to rotate through the connecting shaft 104, the annular plate 106 and other components to bind the binding wire to the steel bar.

[0042] When binding is still required even without power, rotate the second hand-tightening bolt 320 to separate it from the protective sleeve 318. Rotate the connecting rod 102 to align the first through hole 105 with the second threaded hole 317. Then, tighten the second hand-tightening bolt 320 between the second threaded hole 317 and the first through hole 105. Loosen the first hand-tightening bolt 109 to separate it from the second through hole 107. Rotate the binding hook body 1 around the connecting shaft 104 to form an angle between the binding hook body 1 and the connecting rod 102. Finally, connect the first hand-tightening bolt 109 to the corresponding second through hole 107. Figure 6 As shown, the overall shape is similar to a traditional manual wire tying hook, which can be used for manual wire tying temporarily when there is no power. That is, this application has both electric and manual working modes, which improves the applicability of this application.
