A cylindrical mounting hole is arranged in the middle of the positioning block 14, a bearing 15 is mounted in the mounting hole, and both ends of the screw rod 13 are respectively abutted on the bearing 15. An adjusting knob 16 is abutted on the top end of the screw rod 13, and the adjusting knob 16 can drive the screw rod 13 to rotate by screwing.

[0027] A sliding block 17 is mounted on the screw rod 13, and a thread matched with the screw rod 13 is arranged on the sliding block 17. The shape of the sliding block 17 matches the sliding groove.

[0028] When the sleeve 22 is inserted into the sleeve 18, the clamping block 25 is extruded to the center position of the elastic clamping plate 24 under the action of the inner wall of the sleeve 18. When the elastic clamping plate 24 is extruded, the elastic clamping plate 24 is elastically deformed, and the elastic potential energy is stored. With the movement of the clamping block 25 on the sleeve 22 to the clamping groove 19 in the sleeve 18, the clamping block 25 slides into the clamping groove 19 under the action of the elastic force of the elastic clamping plate 24, so that the connecting piece 21 and the sliding block 17 are abutted.

[0029] Two through-slots 27 are symmetrically arranged on the connecting piece 21 at positions on both sides of the sleeve 22, and the rear end of the connecting piece 21 is provided with two fixing plates 26, which are integrally formed in an L shape and symmetrically distributed on both sides of the connecting piece 21.

The slot 28 can be docked with the through-slot 27 on the connecting piece 21, and the fixing plate 26 and the connecting piece 21 are fixedly connected by a fixing bolt. The long side of the fixing plate 26 can be fixedly connected with the vertical keel 11.

[0030] The horizontal keel 31 is fixedly connected in the slot of the connecting piece 21. It should be noted that two connecting pieces 21 are arranged on each of the two vertical keels 11, and the horizontal keel 31 is arranged between the two connecting pieces on the upper and lower two horizontal directions. The upper and lower two horizontal keels 31 are parallel to each other, and the horizontal keel 31 has the same structure as the vertical keel 11, and the cross section is rectangular. The horizontal keel 31 is provided with a horizontal inner expansion groove 32 extending along the length direction of the horizontal keel 31. The horizontal inner expansion groove 32 has the same shape as the vertical inner expansion groove 32, and the slot is an inwardly inclined slope. The slot is a rectangular slot. A test piece 33 is arranged in each of the horizontal inner expansion grooves 32 of the upper and lower two horizontal keels 31. The test piece 33 has a long strip structure formed by splicing two trapezoids. The test piece 33 is arranged in the sliding groove of the horizontal keel 31 by clamping. The two inclined sides at the upper end of the test piece 33 are cut with the slot of the horizontal inner expansion groove 32. The test piece 33 can be clamped in the horizontal inner expansion groove 32 and can move horizontally in the horizontal inner expansion groove 32.

[0031] A tension rod 34 is connected between the upper and lower two horizontal keels 31. The tension rod 34 is perpendicular to the two horizontal keels 31, and the two ends of the tension rod 34 are fixedly connected with the test pieces 33 by bolts. At this time, the tension rod 34 can move horizontally on the two horizontal keels 31. When the two horizontal keels 31 are parallel and straight, the test pieces 33 at the two ends of the tension rod 34 can smoothly move from one end to the other end in the respective sliding grooves. If the horizontal keel 31 is bent or the two horizontal keels 31 are no longer parallel due to external force during use, the relative positions of the test pieces 33 at the two ends of the tension rod 34 in the sliding grooves will deviate, and they will no longer be on the same horizontal or vertical straight line, so the tension rod 34 cannot continue to move. It should be noted that the horizontal inner expansion groove 32 has the same shape as the vertical inner expansion groove 12, and the test piece 34 can be arranged in the vertical inner expansion groove 12 and connected with the tension rod 34 between the two vertical keels 11.

[0032] Threaded through holes are provided at both ends of the test piece 33, and adjusting bolts are installed in the threaded holes. The adjusting bolts can pass through the test piece 33, and their tops can press against the bottom surface of the transverse inner expansion groove 32, fixing the test piece 33 in the transverse inner expansion groove 32 so that it cannot move. At this time, the tie rod 34 can play the role of stabilizing the two transverse keels 31.

[0033] Working principle: The operator can fix the vertical keel 11 to the embedded part, and install the spiral rod 13 and slider 17 in the vertical inward expansion groove 12 of the vertical keel 11. Then, the connector 21 is connected to the slider 17. After adjusting the angle, the connector 21 can be fixed by the fixing plate 26, and the horizontal keel 31 is installed on the connector 21. At this time, the test piece 33 can be installed in the horizontal inward expansion groove 32 of the horizontal keel 31, and the tie rod 34 is vertically installed between the two horizontal keels 31. Pushing the tie rod 34 from one end of the horizontal keel 31 to the other end from the middle position of the tie rod 34, if the embedded part is in the correct position, the tie rod 34 can move smoothly from one end of the horizontal keel 31 to the other end. If the tie rod 34 cannot move further, the following situations may occur:

[0034] 1. If the two connectors 21 are not on the same horizontal line, the fixing plate 26 needs to be loosened from the vertical keel 11, and the adjusting knob 16 should be inserted into the upper end of the spiral rod 13. Then, turn the adjusting knob 16 to make the slider 17 drive the connecting block to move vertically. After adjusting the two connecting blocks to the same horizontal line, the connector 21 can be fixed to the vertical keel 11 by the fixing plate 26.

[0035] 2. If the connector 21 is tilted, loosen the fixing plate 26, rotate the connector 21 until it is horizontal, and then fix it.

[0036] 3. If the horizontal keel 31 is bent, it is necessary to replace it with a straight horizontal keel 31.

[0037] In addition, the test piece can also be installed in the vertical inward groove, and a tie rod can be connected between the two vertical keels to test the parallelism between the vertical keels.
