All of them use a handle perpendicular to the steel wrench and a sleeve is arranged on the outside of the handle. By shaking the handle (rocker arm), the steel bar can be rotated continuously and quickly to achieve a quick connection between the steel bar and the steel sleeve, which has the advantages of high efficiency and labor saving. However, the external handle of the above-mentioned prior art is only fixed on one side of the steel wrench, and is divided into left and right. It is inconvenient to rotate the steel bars on both sides of the steel sleeve, that is, it is necessary to operate on both sides of the steel bar or use two wrenches with left and right external handles, which limits its use occasions.

[0021] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for the purpose of explaining the present invention and are not intended to limit the present invention. That is, the embodiments described herein are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and illustrated in the drawings herein can be arranged and designed in a variety of different configurations.
[0022] This technology is based on a water purification plant project for the comprehensive improvement of the Qianshan River Basin in Xiangzhou District, Zhuhai City. The project consists of 380 bored cast-in-place piles, including 177 22.2m long steel cages. The steel cages are composed of 32 Φ32HRB400 main bars, with a total of 5664 mechanical connections. In view of this, a high-efficiency, labor-saving and widely applicable quick installation wrench device for steel bar mechanical connection sleeves is designed.
[0023] The present invention is further described in detail below with reference to the embodiments.
[0024] The specific embodiment of the wrench device for quickly installing a steel bar mechanical connection sleeve provided by the utility model is as follows:
[0025] See also Figure 1-4 , suitable for the quick installation wrench device of steel bar mechanical connection sleeve, including a steel bar wrench 1; a hinge seat 2 is provided at the end of the steel bar wrench 1, and the steel bar wrench 1 is rotatably connected to a handle 3 through the hinge seat 2, and a sleeve 4 is rotatably provided on the outer side of the end of the handle 3.
[0026] The rebar wrench 1 used in this embodiment is a conventional rebar wrench 1, comprising a rod 101, a fixed jaw 102, and a movable jaw 103. The fixed jaw 102 is connected to the end of the rod 101, and the movable jaw 103 is rotatably connected to the fixed jaw 102. A torsion spring 104 is provided at the rotatable connection between the fixed jaw 102 and the movable jaw 103, which forces the movable jaw 103 closer to the fixed jaw 102. Opposite sides of the fixed jaw 102 and the movable jaw 103 are provided with anti-slip teeth for gripping the rebar. During rotation, the fixed jaw 102 and the movable jaw 103 clamp onto the two sides of the rebar. When the rebar wrench 1 is driven to rotate, the movable jaw 103 can clamp the rebar.
[0027] In this embodiment, the handle 3 is made of round steel, and the sleeve 4 is a seamless steel pipe. The handle 3 is provided with two annular stopper protrusions 301, located on either end of the sleeve 4. By holding the sleeve 4 outside the handle 3 and the jaws of the rebar wrench 1 gripping the rebar end, the device can be conveniently driven in a continuous circular motion, achieving a quick connection between the rebar and the steel sleeve. This improves efficiency, saves manpower, shortens construction time, and brings certain economic and social benefits.
[0028] The handle 3 is rotatably connected to the rebar wrench 1 via the hinge 2. The handle 3 can drive the rebar wrench 1 to rotate at different angles. To improve the stability of the angle between the handle 3 and the rebar wrench 1 when rotating the rebar, this embodiment has a positioning structure that limits the angle between the handle 3 and the rebar wrench 1. The positioning structure enables the handle 3 to have a first state perpendicular to the first side of the rebar wrench 1, a second state perpendicular to the second side of the rebar wrench 1, and a third state coaxial with the rebar wrench 1.
[0029] The positioning structure includes a movable ring 5, which is sleeved on the outside of the handle 3 and slides along the outside of the handle 3; a positioning block 501 is provided on the side of the movable ring 5 facing the hinge seat 2; a coil spring 6 supporting the movable ring 5 is provided on the outside of the handle 3, and the coil spring 6 is sleeved on the outside of the handle 3, one end of the coil spring 6 is connected to the limiting protrusion 301, and the other end is connected to the movable ring 5; the coil spring 6 makes the movable ring 5 close to the hinge seat 2.
[0030] The hinge seat 2 is U-shaped, and the edges of both ends of the U-shape have corresponding semicircular edges. The edge of the hinge seat 2 is provided with at least three positioning grooves 201 that cooperate with the positioning blocks 501. In this embodiment, three positioning grooves 201 are provided on the edges of both ends of the hinge seat 2, and the positioning grooves 201 at both ends of the hinge seat 2 correspond to each other. The movable ring 5 is provided with two positioning blocks 501 on the side facing the hinge seat 2, which respectively cooperate with the positioning grooves 201 at both ends of the hinge seat 2. The corresponding angles between the three positioning grooves 201 at the same end of the hinge seat 2 and the adjacent positioning grooves 201 are all ninety degrees. When the positioning blocks 501 are respectively extended into the three different positioning grooves at the end of the hinge seat 2, the movable ring 5 is provided with two positioning blocks 501. When the positioning block 501 is matched with the two positioning grooves 201 on both sides of the hinge seat 2, the handle 3 is respectively located on the left and right sides of the steel bar wrench 1, and can be used as the left handle 3 steel bar wrench 1 and the right handle 3 steel bar wrench 1. When the positioning block 501 is matched with the middle positioning groove 201 of the hinge seat 2, the handle 3 can form a straight handle corresponding to the rod body 101 of the steel bar wrench 1, which plays a role of lengthening and increasing the force torque of the straight handle steel bar wrench 1.
[0031] During use, the movable ring 5 is driven to move outside the handle 3, compressing the coil spring 6, causing the positioning block 501 to separate from the positioning slot 201, allowing the handle 3 to rotate 180 degrees around the U-shaped hinge 2. When the positioning block 501 of the movable ring 5 corresponds to a positioning slot 201, the movable ring 5 is released, and the coil spring 6 forces the movable ring 5 toward the hinge 2, allowing the positioning block 501 to extend into the positioning slot 201 of the hinge 2, thereby cooperating to position the handle 3.
[0032] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments without inventive effort, or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
