[0015] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0016] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown in the figure, a locking device for wedge-shaped block locking strip includes a locking guide rod 1 and a locker 2. The locking guide rod 1 is composed of a mounting guide rod 11 and a locking screw 12. The locking screw 12 is provided with an anti-rotation flat surface 13. The locker 2 includes a front lock body 21, a rear lock body 22, a middle lock body 23 and a compression spring 24. The middle of the front lock body 21 is provided with an anti-rotation sliding groove 25. The front lock body 21 is sleeved on the locking screw 12 through the anti-rotation sliding groove 25. The anti-rotation sliding groove 25 is in contact with the anti-rotation flat surface 13. The middle lock body 23 is threadedly connected with the locking screw 12. The outer circle of the middle lock body 23 is provided with an outer spline 26. The inner hole of the rear lock body 22 is provided with an inner spline 27. The rear lock body 22 is sleeved on the middle lock body 23. The outer spline 26 is connected with the inner spline 27. The middle lock body 23 is slidingly connected with the rear lock body 22 through the outer spline 26 and the inner spline 27. The compression spring 24 is arranged between the rear lock body 22 and the middle lock body 23. The rear side of the front lock body 21 and the front side of the rear lock body 22 are uniformly provided with a plurality of matching ratchet teeth in a circular array. The teeth of the ratchet teeth are triangular. The outer circle of the rear lock body 22 is provided with anti-skid lines.

[0017] As shown in the figure, Figure 5 and Figure 6 In order to reduce the production cost, another technical solution for the structure of the rear lock body 22 and the middle lock body 23 is provided. The outer circle of the middle lock body 23 is provided with a lock body sliding groove 28. The inner hole of the rear lock body 22 is provided with a lock body sliding pin 29. The lock body sliding pin 29 is inserted into the lock body sliding groove 28. The middle lock body 23 is slidingly connected with the rear lock body 22 through the lock body sliding groove 28 and the lock body sliding pin 29.

[0018] The method for using the locking device is as follows: the plurality of wedge blocks are sequentially installed on the installation guide rod 11, the locker 2 is installed on the locking screw 12, when the locking device needs to be locked, the rear lock body 22 is rotated clockwise by hand, the middle lock body 23 is driven to rotate inward on the locking screw 12 through the connecting structure of the outer spline 26 and the inner spline 27 or the connecting structure of the lock body sliding groove 28 and the lock body sliding pin 29, the rear lock body 22 is pushed by the middle lock body 23 through the compression spring 24, the front lock body 21 is pushed to translate inward on the locking screw 12 by the rear lock body 22, the wedge blocks are pushed to move outward along the wedge inclined surface to be locked, when the rear lock body 22 is initially rotated clockwise, the elastic pressure of the compression spring 24 is small, the ratchet teeth on the front side of the rear lock body 22 and the ratchet teeth on the rear side of the front lock body 21 are easily slipped and jump, with the middle lock body 23 being rotated inward to extrude the compression spring 24, the elastic pressure of the compression spring 24 is gradually increased, at the same time, the front lock body 21 is translated inward to gradually increase the locking force of the wedge blocks, the ratchet teeth are gradually dull, the degree of the ratchet teeth being slipped and jumping when the rear lock body 22 is rotated clockwise can be used to conveniently and accurately judge the size of the locking force of the wedge blocks, the locking force can be adjusted and easily controlled, the wedge blocks are locked through the elastic pressure of the compression spring 24, the locking force is stable and consistent, the locking is firm and reliable, when the locking device needs to be unlocked, the rear lock body 22 is pulled outward by hand, the ratchet teeth are separated, the rear lock body 22 is counterclockwise rotated to drive the middle lock body 23 to rotate outward on the locking screw 12, the front lock body 21 and the wedge blocks are loosened to be unlocked.

[0019] Not limited to this, any change or replacement not thought through creative labor should be covered in the protection scope of the utility model. Therefore, the protection scope of the utility model should be limited by the protection scope defined in the claims.
