The driving part can be driven by manpower or by a combination of the manpower driving and the electric driving, wherein the manpower driving is mainly used for avoiding the damage of the bolt caused by overlarge pre-tightening force applied by the bolt in the tightening process; of course, pure electric drive can be adopted under the condition that electric drive is accurate.
In a specific embodiment, the driving part is driven by manpower, and can be specifically set as a crank 4; obviously, a supporting structure for rotating the first transmission rod 1 is further arranged at the circumferential outer part of the first transmission rod 1; crank 4 is fixed in the axle head of first transfer line 1, and drive crank 4 rotates and can drive first transfer line 1 for the bearing structure pivot to it is rotatory to drive second transfer line 2, dress card portion 3 and bolt.
Further, the first transmission rod 1 is provided with an installation hole extending along the axial direction; the inner wall of the mounting hole is provided with a stopping part for preventing the second transmission rod 2 inserted into the mounting hole from rotating around the central shaft of the second transmission rod 2 so as to realize the synchronous rotation of the second transmission rod 2 along with the first transmission rod 1. Specifically, the second transmission rod 2 is coaxially inserted into the first transmission rod 1 and can move along the axial direction of the first transmission rod 1, and the inner wall of the installation hole of the first transmission rod 1 is provided with a stopping part which can limit the second transmission rod 2 to rotate around the central axis.
The stopping part can be arranged as a convex strip of the inner wall of the mounting hole, specifically, the first transmission rod 1 and the second transmission rod 2 are both cylindrical, and the inner wall of the mounting hole of the first transmission rod 1 is provided with at least one convex strip which extends along the axial direction of the first transmission rod 1; correspondingly, the outer wall of the second transmission rod 2 is provided with grooves which are equal in number to the convex strips and can be matched with the convex strips, and the grooves extend along the axial direction of the second transmission rod 2, namely along the axial direction of the first transmission rod 1. When the sand grip inlay card was in the recess, the sand grip can be at the extending direction of recess back-and-forth movement to realize the telescopic connection of first transfer line 1 and second transfer line 2, and the lateral wall of recess has restricted the rotation of sand grip at the circumferential direction of arbitrary transfer line, can realize the circumference of first transfer line 1 and second transfer line 2 and fix.
Besides the above arrangement, the stopper can also be assumed by the shapes of the first transmission rod 1 and the second transmission rod 2, for example, the installation hole in the first transmission rod 1 is a polygonal hole, for example, the cross section of the installation hole is triangular, rectangular, pentagonal, etc.; the second transmission rod 2 can then be adapted to the installation opening, for example, the cross section of the second transmission rod 2 is triangular, rectangular, pentagonal, etc. In this embodiment, the mounting hole is a non-rotating body, so that the second transmission rod 2 inserted into the mounting hole cannot rotate in the mounting hole, thereby realizing circumferential fixation of the first transmission rod 1 and the second transmission rod 2. Obviously, based on this principle, the cross section of the mounting hole can also be a non-circular closed curve pattern, such as an ellipse; correspondingly, the cross section of the second transmission rod 2 is a non-circular closed curve pattern which can be inserted into the mounting hole.
In order to simplify the processing and manufacturing of the first transmission rod 1 and the second transmission rod 2, the mounting hole in the first transmission rod 1 is a square hole, and the cross section of the second transmission rod 2 is square.
