[0021] The positioning device 2 includes a supporting vertical plate 9, a first positioning bolt 10 and a contact side frame 11. The first positioning bolt 10 is threadedly inserted into the top end of the supporting vertical plate 9, and the contact side frame 11 is slidably inserted into the front end of the supporting vertical plate 9, allowing the contact side frame 11 to move in a straight line inside the supporting vertical plate 9.

[0022] The supporting device 3 includes a second positioning bolt 12, a U-shaped supporting frame 13, a displacement cross frame 14 and a side support rod 15. The side support rods 15 are fixedly installed on both sides of the inside of the U-shaped supporting frame 13. The displacement cross frame 14 is slidably inserted between the two side support rods 15. The second positioning bolt 12 is threaded through the center of the U-shaped supporting frame 13 and is rotatably connected to the displacement cross frame 14. When the second positioning bolt 12 is screwed, it can drive the displacement cross frame 14 to move.

[0023] The support vertical plate 9 is fixedly mounted on one end of the H-shaped sliding key 4 away from the U-shaped connecting frame 8 , and the H-shaped sliding key 4 is symmetrically slidably inserted into the interior of the displacement cross frame 14 , allowing the H-shaped sliding key 4 to slide inside the displacement cross frame 14 .

[0024] The top and bottom of the side end of the displacement cross frame 14 near the second positioning bolt 12 are equidistantly provided with circular holes, and the centers of both ends of the displacement cross frame 14 are provided with sliding grooves to prevent the H-shaped sliding key 4 from being skewed.

[0025] The first positioning bolt 10 is vertically aligned with the contact side frame 11 , thereby improving the docking accuracy of the contact side frame 11 to the first positioning bolt 10 .

[0026] Working principle: When in use, first place the external workpiece on the inner side of the U-shaped support frame 13 close to the displacement cross frame 14, and then install the U-shaped support frame 13 on the external equipment or wall, so that the U-shaped support frame 13 can be supported to perform the limiting work. After that, the second positioning bolt 12 can be screwed and rotated to drive the displacement cross frame 14 to move, and the two ends of the displacement cross frame 14 are slidably sleeved on the side end support rod 15, so that the displacement cross frame 14 can be supported to move along a straight line. At the same time, when the displacement cross frame 14 squeezes the workpiece and contacts the external equipment surface or wall, the workpiece can complete the limiting work. When limiting is required When the workpieces of different specifications are used, the U-shaped connecting frame 8 can be pulled toward the end away from the H-shaped sliding key 4 until the limiting rod 6 moves out of the circular hole inside the front end of the displacement cross frame 14, so that the H-shaped sliding key 4 can be released. After that, the H-shaped sliding key 4 can be moved in the displacement cross frame 14, and the H-shaped sliding key 4 moves in the sliding grooves at both ends of the displacement cross frame 14, so that the H-shaped sliding key 4 can be ensured to move in a straight line. After that, when the H-shaped sliding key 4 drives the contact side frame 11 to move to the side end of the workpiece, the U-shaped connecting frame 8 can be released, and the elasticity of the reset spring 5 will drive the limiting rod 6 to reset quickly until the limiting rod 6 is inserted. The circular hole inside the front end of the displacement cross frame 14 completes the restriction work on both sides of the H-shaped sliding key 4. When the device is in use, the circular hole spacing at the front end of the displacement cross frame 14 is 1 cm, so that the device can be adapted to workpieces of different specifications. At the same time, the first positioning bolt 10 can be screwed and rotated to disengage from the contact side frame 11, so that the contact side frame 11 can be released, and the contact side frame 11 is easy to adjust inside the supporting vertical plate 9, so that the contact side frame 11 can contact with the surfaces of workpieces of different lengths. Afterwards, when the working length of the contact side frame 11 is determined, the first positioning bolt 10 can be screwed and rotated to disengage from the contact side frame 11 are fastened together, so that the contact side frame 11 can be restricted and fixed to prevent the contact side frame 11 from sliding again, thereby completing the restriction work on workpieces of different specifications and sizes. When the device is in use, the H-shaped sliding key 4 can slide inside the displacement cross frame 14, and the H-shaped sliding key 4 is limited by inserting the limiting rod 6 into the circular hole inside the front end of the displacement cross frame 14, so that the contact side frame 11 can limit the two sides of the workpiece. At the same time, the displacement cross frame 14 is driven to move by screwing the second positioning bolt 12, so that the front end of the workpiece can be squeezed to contact with external equipment or walls, thereby completing the restriction and positioning work of the workpiece.
