Detailed Description of the Preferred Embodiment

[0023] As Figures 1-3 shown, the present utility model provides a steel bar connecting sleeve installation tool, including a connecting component 100. The connecting component 100 includes a fixed block 101, a movable block 102, a connecting arm 103, a fastening plate 104, an adjusting arm 105, and an adjusting rod 106. The movable block 102 is located directly below the fixed block 101. The connecting arm 103 is arranged on the outside of the movable block 102. The fastening plate 104 is arranged at the bottom of the connecting arm 103. The adjusting arm 105 is arranged between the movable block 102 and the fixed block 101. The adjusting rod 106 penetrates through the movable block 102 and the fixed block 101;

[0024] An electric wrench 200 is arranged on one side of the fixed block 101. A switch 201 is arranged in the hand-held area of the electric wrench 200. A battery compartment 202 is arranged at the bottom of the electric wrench 200. Clamping blocks 203 are arranged on both sides of the battery compartment 202.

[0025] Further, in this embodiment, connection ends 1011 are provided on the outer sides of the fixed block 101 and the movable block 102. At least two adjusting arms 105 are provided between the connection ends 1011 on the same vertical line. One ends of the two adjusting arms 105 are connected by screws, and the other ends of the two adjusting arms 105 are respectively rotatably connected to the fixed block 101 and the movable block 102. The two adjusting arms 105 are connected by screws, and the large adjusting arm 105 formed by the two adjusting arms 105 is installed between the fixed block 101 and the movable block 102.

[0026] In this embodiment, the upper end of the connecting arm 103 is rotatably connected to the connection end 1011 of the movable block 102. A connecting plate 1010 is fixed to the rear side of the fastening plate 104. The connecting plate 1010 is screwed to the lower end of the connecting arm 103. The connecting arm 103 is screwed to the movable block 102, so that the movable block 102 can drive the connecting arm 103 to move together when moving and rotate inside the connection end 1011 of the movable block 102.

[0027] In this embodiment, the fastening plate 104 is designed in an arc shape, and rubber anti-slip bumps are provided on the outer surface of the fastening plate 104. Through the design of the fastening plate 104, its connection with the steel bar connecting sleeve 300 is more firm.

[0028] In this embodiment, a jack 108 is provided at the upper end of the adjusting rod 106. The adjusting rod 106 is inserted into the output shaft of the electric wrench 200 through the jack 108. The adjusting rod 106 is in transmission connection with the output shaft of the electric wrench 200. The adjusting rod 106 is in threaded cooperation with the movable block 102 and is rotatably connected to the fixed block 101. A convex plate 107 is fixed to the bottom end of the adjusting rod 106. The adjusting rod 106 is installed at the front end of the electric wrench 200 through the jack 108, so that the electric wrench 200 can control the adjusting rod 106 to rotate, and the convex plate 107 blocks the front side of the movable block 102 to prevent the movable block 102 from falling off and limit the moving range of the movable block 102.

[0029] In this embodiment, at least three connection ends 1011 are provided on the outer sides of the fixed block 101 and the movable block 102. Since the structure of a triangle is relatively stable, the fastening plate 104 provided by at least three connection ends 1011 is used to perform three-point fastening on the steel bar connecting sleeve 300, and the number of connection ends 1011 can be set according to requirements.

[0030] In this embodiment, a card frame 204 adapted to the card block 203 is provided at the bottom of the electric wrench 200. The card block 203 is made of rubber. The battery compartment 202 and the electric wrench 200 are clamped by the card block 203 and the card frame 204. Through the cooperation of the elasticity of the card block 203 and the card frame 204, the disassembly and assembly of the battery compartment 202 are realized.

[0031] Specifically, when installing the steel bar connecting sleeve 300, align the connecting component 100 with the barrel opening of the steel bar connecting sleeve 300. Control the rotation of the adjusting rod 106 through the electric wrench 200. The adjusting rod 106 rotates within the fixed block 101 fixed at the front end of the electric wrench 200. Using the thread to control the movement of the outer movable block 102 forward, thereby driving the angle between the same-side adjusting arms 105 to become larger. The angle between the connecting arm 103 and the movable block 102 also becomes larger, which is the stretching effect. This makes the position of the fastening plate 104 at the end of the adjusting arm 105 expand onto the inner wall of the steel bar connecting sleeve 300 and abut against the inner wall of the sleeve. Then align the sleeve with the steel bar, and the electric wrench 200 continues to rotate to screw the sleeve onto the steel bar. Conversely, when it is necessary to release the sleeve, control the electric wrench 200 to rotate in the reverse direction. The movable block 102 moves in the reverse direction, the adjusting arms 105 and the connecting arm 103 contract, and the distance between the fastening plates 104 tightens and withdraws from the sleeve, completing the connection between the steel bar connecting sleeve 300 and the steel bar;

[0032] When it is necessary to install another steel bar at the other end of the steel bar connecting sleeve 300, disassemble the fastening plate 104 on the connecting arm 103, change the inside-out orientation of the fastening plate 104 so that the inner side of the fastening plate 104 faces the outer wall of the steel bar. Still control the contraction of the connecting arm 103 and the adjusting arm 105 through the electric wrench 200, thereby controlling the inward contraction of the fastening plate 104 so that the fastening plate 104 clamps the end of the second steel bar. Continue to rotate the electric wrench 200 to screw its threaded part into the sleeve to achieve the connection of the two steel bars;

[0033] When designing the rotation direction of the electric wrench 200, the thread direction of the adjusting rod 106, and the thread direction of the sleeve, it is necessary to ensure that these directions match each other so that the electric wrench 200 can effectively fasten and release the sleeve. When the electric wrench 200 rotates clockwise, the thread on the adjusting rod 106 is in the clockwise direction, and the thread of the sleeve is in the counterclockwise direction. When the electric wrench 200 rotates clockwise, the adjusting rod 106 will move along the thread direction. When the adjusting rod 106 moves forward, it pushes the sleeve forward to achieve the screwing of the sleeve.

[0034] In addition, the number of adjusting arms 105 and the length of the adjusting rod 106 can be adjusted according to the size of the steel bar connecting sleeve 300 to improve applicability.

[0035] In addition, the electric wrench 200 with a two-way rotation function has the following models: MDS series digital display torque wrench, ETW-S digital display straight shank electric torque wrench, WORX WU279, and DY A3-2106.

[0036] The fixing block 101, movable block 102, connecting arm 103, fastening plate 104, adjusting arm 105, adjusting rod 106, convex plate 107, connecting plate 1010, electric wrench 200, switch 201, battery compartment 202, clamping block 203, clamping frame 204, steel bar connecting sleeve 300 and other components of the present utility model are all common standard components or components known to those skilled in the art, and their structures and principles can all be known to those skilled in the art through technical manuals or obtained through conventional experimental methods.
