However, the diameter of the reinforcing steel bar needs to be subtracted from the measured value to obtain the accurate spacing size, which takes a long time for single detection and is inconvenient to operate.

[0009] Further, the indicating assembly includes an indicating block connected to the periphery of the telescopic column, the fixed cylinder is fixedly connected with an identification block matched with the indicating block, and a through slot is formed in the periphery of the fixed cylinder for the free passage of the indicating block.

[0018] The beneficial effects of the utility model are as follows:

In this utility model, the distance between the first clamping block and the second clamping block is adjusted by sliding the telescopic column inside the fixed cylinder, and the two steel bars are respectively inserted into the V-shaped slots of the first clamping block and the second clamping block. Due to the contour design of the V-shaped slot, the steel bars can be automatically centered after being inserted into the V-shaped slot.

[0021] 3. In this utility model, after the reinforcing bar is inserted into the V-shaped bayonet, it will exert a squeezing force on the detection pin, causing the detection pin to move away from the first clamping block. This causes the rotating part to rotate. When the rotating part rotates, the indicator part will move away from the fan-shaped block, thus determining that the reinforcing bar is in a centered state within the V-shaped bayonet. Otherwise, it is determined that the reinforcing bar is not clamped and needs to be re-clamped and centered. Attached Figure Description

An elastic element 13 is installed inside the fixing cylinder 5. The elastic element 13 can be specifically set as a spring. The two ends of the spring elastic force direction elastically abut against the surface of the first clamping block 6 and the end face of the telescopic column 2, respectively. In the natural state, the elastic element 13 has an elastic abutting force on the telescopic column 2, thereby causing the telescopic column 2 to extend outward from the fixing cylinder 5.

[0033] The telescopic column 2 is connected with the indicating block 12 extending to the radial outside of the telescopic column 2, the indicating block 12 is provided with the arrow corresponding to the opposite sides of the radial of the fixed cylinder 5, the fixed cylinder 5 is fixedly connected with the identification block 11 matched with the arrow on the indicating block 12, the fixed cylinder 5 is provided with the through slot 10 for the indicating block 12 to pass through freely, when the telescopic column 2 slides in the fixed cylinder 5, the distance between the indicating block 12 and the identification block 11 changes, the detection pin 14 is vertically arranged on the first clamping block 6 and can slide freely on the first clamping block 6, one end of the detection pin 14 is inserted into the V-shaped notch, the cylindrical part 8 is fixedly connected to the surface of the first clamping block 6, the bearing groove is arranged on the end surface of the cylindrical part 8, the bearing is arranged in the bearing groove, the inner ring of the bearing is fixedly arranged with the rotating part 15, the rotating part 15 is coaxially fixedly connected with the rotating part 9 on the upper end surface, so that the rotating part 9 is rotatably connected to the end of the cylindrical part 8, the indicating part 21 is fixedly connected to the end surface of the rotating part 9, the fan-shaped block 7 is fixedly connected to the periphery of the cylindrical part 8, the indicating part 21 is matched with the fan-shaped block 7, that is, when the reinforcing steel bar is clamped into the V-shaped notch of the first clamping block 6, the periphery of the reinforcing steel bar will abut against the detection pin 14, so that the detection pin 14 moves towards the inside of the first clamping block 6, when the sharp part of the indicating part 21 is in the projection range of the fan-shaped block 7, it can be determined that the reinforcing steel bar is not clamped in the V-shaped notch, the rolling ball 22 is rotatably arranged on the periphery of the detection pin 14, the through hole 19 is coaxially arranged on the end of the rotating part 15 for the detection pin 14 to pass through freely, the spiral rolling groove 20 is arranged on the inner wall of the through hole 19 for the rolling ball 22 to be clamped, the rolling ball 22 freely rolls in the spiral rolling groove 20, the limiting ring 17 is fixedly sleeved on the periphery of the detection pin 14, the empty slot 18 is arranged in the cylindrical part 8 for the limiting ring 17 to pass through freely, the reset spring 16 is sleeved on the periphery of the detection pin 14, the both ends of the reset spring 16 in the elastic force direction elastically abut against the rotating part 15 and the bottom wall in the inner cavity of the empty slot 18 respectively, in addition, the protrusion is fixedly connected to the periphery of the limiting ring 17, the sliding groove is arranged on the inner wall of the empty slot 18 for the protrusion to slide and be clamped, through the sliding and limiting of the protrusion in the sliding groove, the limiting ring 17 cannot rotate in the sliding groove.

[0034] The working principle of the embodiment is as follows:

[0035] The V-shaped notch on the second clamping block 1 is clamped into the periphery of one of the reinforcing steel bars, and the second clamping block 1 is pressed towards the reinforcing steel bar, so that the reinforcing steel bar is centered in the V-shaped notch of the second clamping block 1, then the first clamping block 6 is pressed, so that the first clamping block 6 drives the fixed cylinder 5 to move towards the second clamping block 1, until the V-shaped notch on the first clamping block 6 corresponds to the position of the other reinforcing steel bar, then the V-shaped notch on the first clamping block 6 is clamped on the periphery of the reinforcing steel bar, during the clamping process, since the detection pin 14 protrudes into the V-shaped notch, the end of the detection pin 14 will be in contact with the periphery of the reinforcing steel bar, and the reinforcing steel bar will generate a pressing force on the detection pin 14, so that the detection pin 14 moves towards the inside of the first clamping block 6;

[0036] When the motion, the detection pin 14 will make the ball 22 in the spiral rolling groove 20 of the rotating part 15 rolling, and because the protrusion of the limiting ring 17 is engaged in the sliding groove, the limiting ring 17 will limit the rotation of the detection pin 14, thereby making the rotating part 15 rotate, and driving the rotating part 9 to rotate. When rotating, whether the observation indicating part 21 is away from the sector block 7, if the indicating part 21 is still located in the projection area of the sector block 7 (i.e. whether the indicating part 21 is located in the area corresponding to the top surface of the sector block 7 from the perspective), it indicates that the movement stroke of the detection pin 14 is not in place, and then it can be determined that the steel bar is not fully centered and clamped in the V-shaped clamping hole (the hand of the worker always keeps pressing the second clamping block 1, so that the V-shaped clamping hole on the second clamping block 1 is clamped with the steel bar, that is, the steel bar corresponding to the second clamping block 1 is in the centered state), so the first clamping block 6 needs to be pressed to clamp and center the steel bar in the V-shaped clamping hole of the first clamping block 6, if the indicating part 21 is located outside the projection area of the sector block 7, it can be determined that the steel bar is clamped and centered in the V-shaped clamping hole of the first clamping block 6.

[0037] When the fixed cylinder 5 moves relative to the telescopic column 2, the indicating block 12 will move towards the direction of the identification block 11, if the arrow on the indicating block 12 is located in the projection area of the identification block 11, it indicates that the spacing size of the two steel bars is within the qualified range, otherwise, if the arrow on the indicating block 12 is located outside the projection area of the identification block 11, it indicates that the spacing size of the steel bars is not within the qualified range.

[0038] The above is only a preferred embodiment of the present application, and is not used to limit the protection scope of the present application.
