[0022] Further, a second magnet is arranged on the side of the sliding rod close to the push block, so that the sliding rods on two sides attract each other.

[0023] Further, a third magnet is arranged on the end of the push block close to the first magnet, so that the driving rod moves the push block to the direction of the driving rod when the driving rod is close to the push block.

[0066] It should be noted that the terms "a" and "a plurality of" used in this disclosure are illustrative rather than restrictive, and those skilled in the art should understand that, unless otherwise expressly indicated in the context, they should be understood as "one or more".

[0067] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0068] Example 1: Refer to Figures 1-8 An adjustable stirrup for reinforcing bars includes: a horizontal bar 101, a vertical bar 102, a rotating shaft 103, a locking tooth 104, a push block 105, a drive rod 106, a locking bar 107, and a first magnet 108. The horizontal bar 101 supports the reinforcing bars. The vertical bar 102 is located at both ends of the horizontal bar 101, and a sliding groove 102a is provided on the vertical bar 102 for the horizontal bar 101 to slide up and down. First locking grooves 102b are provided on the side walls of the sliding groove 102a. The rotating shaft 103 is rotatably located at both ends of the horizontal bar 101. Multiple crossbars 101 are slidably arranged on the top; locking teeth 104 slide along the axial direction of the rotating shaft 103 and are located on both sides of the crossbars 101. The locking teeth 104 can be embedded in the first locking groove 102b to fix the crossbars 101 to the vertical bar 102; an abutment strip 109 is integrally formed on the vertical bar 102 and is located at the two side openings of the sliding groove 102a. The abutment strip 109 abuts against the two side walls of the locking teeth 104 so that the locking teeth 104 will not disengage from the sliding groove 102a, thereby fixing the crossbars 101 in the length direction.

[0069] Push block 105 is slidably disposed within rotating shaft 103. Push block 105 slides along the length of crossbar 101 and is located between two retaining teeth 104, used to push retaining teeth 104 into first retaining groove 102b. A third magnet 110 is fixed on the end of push block 105 near drive rod 106. Drive rod 106 is threadedly connected to crossbar 101. The axis of drive rod 106 is parallel to the length of crossbar 101 and is used to drive push block 105. 05 moves towards the drive rod 106; multiple placement slots 103a are provided on the circumferential surface of the rotating shaft 103, and the placement slots 103a are arranged in a ring around the axis of the rotating shaft 103. A retaining strip 107 is slidably provided in the placement slot 103a, and a second retaining slot 101a is provided on the crossbar 101 for the retaining strip 107 to be partially inserted; a first magnet 108 is fixed on the drive rod 106 near the end of the push block 105, and the retaining strip 107 can be attracted by the first magnet 108.

[0070] When using the stirrups, the operator adjusts the spacing between adjacent crossbars 101 according to actual usage needs. After confirming the spacing between adjacent crossbars 101, the operator rotates the drive rod 106, causing the drive rod 106 to move closer to the push block 105. When the first magnet 108 and the third magnet 110 approach each other, the third magnet 110 is attracted by the first magnet 108, causing the push block 105 to move towards the drive rod 106. The push block 105 pushes the locking teeth 104 on both sides outward, so that the locking teeth 104 are embedded in the first locking groove 102b, thereby fixing the up and down sliding of the crossbar 101.

[0071] When the plane on which the vertical bars 102 on both sides are placed is not level, the angle between the horizontal bar 101 and the vertical bar 102 can be adjusted so that the horizontal bar 101 can always be in a horizontal position. Before adjusting the angle between the horizontal bar 101 and the vertical bar 102, one end of the horizontal bar 101 is completely fixed, the other end of the drive rod 106 is still in the initial position, the first magnet 108 and the third magnet 110 have not yet attracted each other, and the locking strip 107 is completely in the placement slot 103a. At this time, the operator turns one end of the horizontal bar 101 to make the horizontal bar 101 swing relative to the rotating shaft 103, so that the horizontal bar 101 is adjusted to a horizontal state. Then, the drive rod 106 is rotated to move the drive rod 106 towards the push block 105. The first magnet 108 will attract the locking strip 107, so that the locking strip 107 is locked into the second locking slot 101a, thereby stopping the rotation of the end of the horizontal bar 101 that has not yet been fixed and fixing the horizontal bar 101.

[0072] The system is equipped with a horizontal bar 101, a vertical bar 102, a rotating shaft 103, a locking tooth 104, a push block 105, a drive rod 106, a locking strip 107, and a first magnet 108, which allows the horizontal bar 101 to slide up and down on the vertical bar 102 and to rotate and swing relative to the vertical bar 102. The operation is simple; simply rotating the drive rod 106 to move it inward or outward is sufficient to achieve the synchronous closing and opening of the vertical bar 102's sliding up and down and rotation.

[0073] A slide rod 112 is integrally formed on the side of the locking teeth 104 that are close to each other. A through hole 103b is provided at the axis of the rotating shaft 103, which runs through the axis of the rotating shaft 103. The slide rod 112 slides in the through hole 103b. The slide rod 112 has a second inclined surface 112a, and the push block 105 has a first inclined surface 105a. The first inclined surface 105a and the second inclined surface 112a can abut against each other so that when the push block 105 moves in the direction of the drive rod 106, it can push the slide rods 112 on both sides of the push block 105 to move outward, thereby driving the locking teeth 104 to be inserted into the first locking groove 102b.

[0074] A second magnet 113 is fixed on the side of the slide bar 112 near the push block 105 so that the slide bars 112 on both sides can attract each other. When the drive rod 106 moves away from the push block 105, the first magnet 108 and the third magnet 110 no longer attract each other. At this time, the second magnets 113 on the slide bars 112 on both sides attract each other, pushing the push block 105 out from between the slide bars 112 on both sides. The slide bars 112 on both sides attract each other, so that the locking teeth 104 on both sides disengage from the first locking groove 102b, thereby canceling the vertical sliding restriction of the crossbar 101.

[0075] A clearance groove 112b is provided on the side of the slide rod 112 near the push block 105 to give space to the push block 105, so that the slide rods 112 on both sides can fit together.

[0076] A fourth magnet 114 is attached to the bottom of the placement slot 103a so that the card strip 107 can be fixed in the placement slot 103a without falling off when it is not attracted by the first magnet 108. The attraction of the fourth magnet 114 to the card strip 107 is less than that of the first magnet 108 to the card strip 107, so that when the card strip 107 is attracted by the fourth magnet 114, the first magnet 108 can also attract the card strip 107, so that the card strip 107 is inserted into the second card slot 101a. When the first magnet 108 separates from the card strip 107, the card strip 107 can be attracted back into the placement slot 103a by the fourth magnet 114.

[0077] To facilitate the installation of components, the rotating shaft 103 is composed of a pair of cylinders, and the crossbar 101 is composed of a main rod 101b and a secondary rod 101c. The crossbar 101 is fixed to both ends of the main rod 101b.

[0078] Multiple limiting grooves 101d are provided on the upper end face of the main rod 101b to limit the sliding of the reinforcing bars.

[0079] Example 2: A stirrup with adjustable rebar spacing based on Example 1 and a rebar spacing adjustment method, including the following steps:

[0080] S1. Confirm the distance between adjacent horizontal bars;

[0081] S2. Slide the horizontal bar to the desired height;

[0082] S3. Confirm the horizontal position of the crossbar;

[0083] S4. Swing the horizontal bar to a horizontal position;

[0084] S5. Rotate the drive rod and move it toward the push block;

[0085] S6. The swinging and sliding of the fixed crossbar.

[0086] Specifically, when the vertical bars 102 on both sides are placed horizontally, the operator adjusts the spacing between adjacent horizontal bars 101 according to actual usage needs. After the spacing between adjacent horizontal bars 101 is confirmed, the operator rotates the drive rod 106, causing the drive rod 106 to move towards the push block 105. When the first magnet 108 and the third magnet 110 approach each other, the third magnet 110 is attracted by the first magnet 108, causing the push block 105 to move towards the drive rod 106. The push block 105 pushes the locking teeth 104 on both sides outward, so that the locking teeth 104 are embedded in the first locking groove 102b, thereby fixing the up and down sliding of the horizontal bar 101.

[0087] When the plane on which the vertical bars 102 on both sides are placed is not level, the angle between the horizontal bar 101 and the vertical bar 102 can be adjusted so that the horizontal bar 101 can always be in a horizontal position. Before adjusting the angle between the horizontal bar 101 and the vertical bar 102, one end of the horizontal bar 101 is completely fixed, and the drive rod 106 at the other end is still in the initial position. The first magnet 108 and the third magnet 110 have not yet attracted each other, and the locking strip 107 is completely in the placement slot 103a. At this time, the operator turns one end of the horizontal bar 101 to make the horizontal bar 101 swing relative to the rotating shaft 103, so that the horizontal bar 101 is adjusted to a horizontal state. Then, the drive rod 106 is rotated to move the drive rod 106 towards the push block 105. The first magnet 108 will attract the locking strip 107, so that the locking strip 107 is locked into the second locking slot 101a, thereby stopping the rotation of the end of the horizontal bar 101 that has not yet been fixed and fixing the horizontal bar 101. Therefore, this invention can conveniently adjust the spacing between the upper and lower reinforcing bars and adjust the horizontal position of the reinforcing bars, and has the advantages of convenient adjustment and simple operation.
