A first vertical plate 314 is arranged on one side of the base 31 near the metal rod part 91, a containing cavity 3140 is axially penetrated on the first vertical plate 314, the upper end of the containing cavity 3140 is hinged with a conducting plate 44,

The device further comprises a first driving device 35 on the basis of embodiment 1, wherein the first driving device 35 is used for reducing the distance between the base 31 and the mounting seat 2 to a preset value, and the sliding block 32 is pushed by the front end of the metal rod part 91 and slides relative to the base 31; the sliding block 32 is provided with a first conductive piece 33, the first conductive piece 33 moves synchronously with the sliding block 32, and the base 31 is provided with a second conductive piece 34; the anchor inserter further comprises a length detection circuit electrically connected with the first conductive piece 33 and the second conductive piece 34, and when the base 31 is pushed by the metal rod portion 91 and slides to the first conductive piece 33 and the second conductive piece 34 to be contacted, the length detection circuit judges whether the length of the anchor inserter 9 is qualified or not.
The concentricity detection device for an anchor inserter according to this embodiment can also detect the length of the anchor inserter 9, and the principle of detecting the length is as follows: the first driving device 35 drives the base 31 and/or the mounting base 2 to move, so that the distance between the base 31 and the mounting base 2 is reduced to a preset value, at this time, the sliding block 32 is pushed by the front end of the metal rod portion 91 and slides relative to the base 31, and since the distance between the base 31 and the mounting base 2 is a fixed preset value, if the overall length of the anchor inserter 9 is changed, the sliding distance of the sliding block 32 on the base 31 is also changed, and if the sliding distance of the sliding block 32 is within a preset interval, the length of the anchor inserter 9 is qualified; otherwise, the test is not qualified. In the present application, the sliding block 32 is in contact with the metal rod 91, so that the force applied to the end of the metal rod 91 by the driving member during braking can be greatly reduced, and the metal rod 91 is prevented from being bent. In this embodiment, the displacement of the sliding block 32 is detected by using a conductive contact method, which has the advantages of high detection accuracy and low cost. Therefore, in the device for detecting the length and concentricity of the anchor inserter according to the present embodiment, whether the length and concentricity of the anchor inserter 9 are qualified or not is detected by using the sliding block 32 and the conductive pulling piece 411 which are in weak contact, so that on one hand, the detection of the length and concentricity of the anchor inserter 9 can be realized, and the product quality is ensured; on the other hand, deformation of the anchor inserter 9 during the detection process can be prevented from affecting the product quality.
Further, referring to fig. 9, the base 31 includes a bottom plate 313, the second conductive member 34 is embedded on an upper end surface of the bottom plate 313, the second conductive member 34 is in a sheet shape, the second conductive member 34 is hinged to the sliding block 32, and the bottom end of the second conductive member 34 is attached to the bottom plate 313 by self gravity. When the first conductive member 33 and the second conductive member 34 are in contact, the length detection circuit thereby determines that the length of the anchor inserter 9 is acceptable. The first conductive member 33 is hinged on the sliding block 32, and the first conductive member 33 is in line/point contact with the bottom plate 313 or the second conductive member 34, so that resistance generated by the contact of the bottom plate 313 against the first conductive member 33 can be reduced, and deformation of the metal rod 91 caused by overlarge resistance can be avoided. And, the second conductive member 34 has a simple overall structure and low production cost.
Further, the first conductive member 33 includes a rotating plate 332 and a contact plate 331, the contact plate 331 is disposed at a front end of the first conductive member 33 contacting the bottom plate 313, the contact plate 331 is disposed vertically, and a bending angle is disposed between the rotating plate 332 and the contact plate 331. Since the first conductive member 33 needs to reciprocate with the sliding block 32, and needs to be in continuous sliding contact with the upper end surface of the bottom plate 313 during the movement, the contact surface (especially at the edge between the bottom plate 313 and the second conductive member 34) will generate a certain resistance to the first conductive member 33. If the front end of the corresponding first conductive element 33 is inclined to the bottom plate 313, a certain amount of bending of the first conductive element 33 will occur after a certain period of operation is accumulated, thereby affecting the accuracy of the length detection result. In the present application, the contact plate 331 is vertically disposed, so that the external forces acting on the contact plate 331 by the contact surface of the first conductive member 33 during the reciprocating movement are symmetrical to each other, so that the whole first conductive member 33 is ensured not to deform, thereby ensuring the length detection precision and prolonging the service life of the length detection device 3.
Specifically, the first driving device 35 is an air cylinder, and is in driving connection with the base 31.
