For example, they can be fixedly connected or detachably connected; they can be directly connected or indirectly connected through intermediate components. For those of ordinary skill in the art, the specific meanings of the above terms can be understood according to specific situations.

[0022] The present invention will be described in detail below with reference to the drawings and in combination with embodiments. It should be noted that, without conflict, the embodiments and features in the embodiments of the present invention can be combined with each other.

[0023] As Figure 1As shown in the figure, a tool for bending auxiliary hooks during on-site construction includes a main body 2 and a bending pipe 5. The main body 2 is a metal square pipe or round pipe. One end of the main body 2 is provided with a holding part 3 for the user to hold. At the other end of the main body 2, a telescopic joint 1 is detachably connected, so that the telescopic joint 1 can be set according to actual needs. By adjusting the telescopic joint 1, the length of the tool changes, so as to achieve telescopic cooperation, and the bending of the hook can be carried out simply and conveniently. The small design is suitable for most working environments. The bending pipe 5 is fixed on the side wall of the telescopic joint 1. A middle hole corresponding to the steel bar to be bent is provided in the middle of the bending pipe 5. The bending pipe 5 is a steel pipe for forming the steel bar. The inner diameter of the middle hole is adapted to the diameter of the corresponding steel bar. By forming a labor-saving lever through the main body 2, while effectively assisting the bending of the hook, the potential safety hazard is reduced.

[0024] In an alternative embodiment, the length of the bending pipe 5 is 10 - 15 cm, and the length of the main body 2 is designed according to actual requirements.

[0025] In an alternative embodiment, the telescopic joint 1 is correspondingly sleeved at the end of the main body 2. The telescopic joint 1 is a metal square pipe or round pipe adapted to the main body 2. The inner diameter of the telescopic joint 1 is adapted to the outer diameter of the main body 2. A pin 4 corresponding to the telescopic joint 1 is provided on the main body 2. The pin 4 is used to lock the relative positions of the telescopic joint 1 and the main body 2 to ensure the stability between the two. A plurality of axially uniformly distributed jacks are provided on the side wall of the telescopic joint 1, so as to realize the telescopic function of the telescopic joint 1. There are five jacks in total, with a total length of 30 cm. Preferably, corresponding jacks are provided on both sides of the telescopic joint 1.

[0026] In an alternative implementation, corresponding jacks are provided on both sides of the telescopic joint 1. The main body 2 is a hollow structure. Two mounting holes located at both ends of the same diameter are provided on the main body 2, so that the pin 4 is inserted into the main body 2 and the telescopic joint 1 along the radial direction and penetrates through.

[0027] Or, a jack is provided on one side of the telescopic joint 1, and a mounting hole corresponding to the pin 4 is provided on the corresponding side of the main body 2. The pin 4 is slidably assembled along the radial direction of the main body 2. A return spring corresponding to the pin 4 is provided inside the main body 2, so as to realize the expansion and contraction of the pin 4, and further meet the purpose of quickly adjusting the telescopic joint 1.

[0028] In an alternative embodiment, the holding part 3 is coated with a rubber material. Generally, the rubber material is made into a rubber sleeve to improve the holding comfort and has an anti-slip effect. An internal thread is provided at one end of the holding part 3, so that a force-increasing rod can be connected. The force-increasing rod can extend along the axial direction of the main body 2. A threaded section is provided at the front end of the force-increasing rod, or a 90-degree bending part is provided at the end of the force-increasing rod, and a threaded end is provided at the end of the bending part to realize the bending of the steel bar at a high place.

[0029] In an alternative embodiment, the front end of the bent pipe 5 extends out of the end of the telescopic joint 1 away from the holding portion 3, so as to ensure that the end of the steel bar can be accurately inserted into the bent pipe 5, avoiding the insertion of the steel bar into the telescopic rod, and a closed baffle is provided at the end of the telescopic rod.

[0030] The bent pipe 5 is fixed to the telescopic joint 1 by welding. The bent pipe 5 and the telescopic joint 1 are arranged in parallel or welded at a certain angle, and no excessive restrictions are imposed specifically.

[0031] In an alternative embodiment, the bent pipe 5 and the telescopic joint 1 are fixed by a sleeve. The sleeve can be welded to fix the side of the telescopic joint 1, and the bent pipe 5 is assembled through the sleeve, so that the bent pipe can be connected to the telescopic joint through both ends respectively. The inner cavity of the sleeve is adapted to the bent pipe 5, or the sleeve is internally provided with threads, and the bent pipe 5 is threadedly assembled in the sleeve, so as to realize the position adjustment of the bent pipe 5. Further, a stepped platform is provided at one end of the bent pipe 5 to form an enlarged hole section, so as to adapt to the bending of steel bars with different diameters. Furthermore, generally, the length of the steel bar extending out of the concrete is not more than 10 cm, generally about 5 - 8 cm. Therefore, the length of the bent pipe 5 is 15 cm, and the length of the enlarged hole section is half of the length of the bent pipe 5, so as to meet the actual bending requirements of multi-specification steel bars.

[0032] The side wall of the sleeve is provided with bolts, and the bolts are pressed against the outer wall of the bent pipe 5 after passing through the sleeve for fixation.

[0033] The side wall of the sleeve is provided with a first connection plate, and the front side wall of the telescopic joint 1 is provided with a second connection plate. The adjacent sides of the first connection plate and the second connection plate are provided with meshing teeth that mesh with each other. The middle of the first connection plate is provided with an adjustment stud, and the adjustment stud passes through the telescopic joint 1 and is connected to a nut. Thus, after the angle of the sleeve is adjusted, it is locked by the nut, so that the first connection plate and the second connection plate are pressed against each other to form a limiting structure and thus maintain the angle, thereby adjusting the angle of the bent pipe 5 through the sleeve.

[0034] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention are within the scope of protection of the pending claims of the present invention.
