[0023] The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments. It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other without conflict. For the convenience of description, if the words "upper", "lower", "left" and "right" appear in the following text, they only indicate that the upper, lower, left and right directions are consistent with the drawings themselves, and do not limit the structure.

[0024] like Figure 1 As shown, a positioning tool provided in this embodiment includes a base 1, a side plate 2, a tool frame 3, a hinge mechanism 4, a first locking mechanism 5 and a second locking mechanism 6.

[0025] like Figure 3 As shown, the side plate 2 is provided with an adjustable degree of freedom relative to the base 1 in the front-rear direction, so that the side plate 2 and the tooling frame 3 can be displaced front-rear.

[0026] like Figure 1 As shown, the tooling frame 3 is provided with fan-shaped plates on both sides, and one side surface of the tooling frame 2 is a positioning surface C. The hinge mechanism 4 is arranged near the center of the fan-shaped plate, and the second locking mechanism 6 is arranged near the arc of the fan-shaped plate. The first locking mechanism 5 is placed between the hinge mechanism 4 and the second locking mechanism 6 in a plug-in manner.

[0027] like Figure 4 As shown, the hinge mechanism 4 includes a shaft 41, a copper sleeve 42 and a retaining ring 43. One end of the shaft 41 is fixed to the fixture frame 3, and the other end of the shaft 41 passes through the hole on the side plate 2 and extends to the outside of the side plate 2. The retaining ring 43 is clamped on the shaft 41 extending to the outside, and the retaining ring 43 is a standard spring retaining ring. The retaining ring 43 abuts against the outer surface of the side plate 2. The copper sleeve 42 is matched between the shaft 41 and the hole of the side plate 2.

[0028] like Figure 1 , Figure 2 As shown, the hinge structure of the tooling frame 3 enables it to rotate relative to the side plate 2. The tooling frame 3 is provided with a plurality of plug holes 31 and long slot holes 32. The plurality of plug holes 31 are formed into two groups, and each group is arranged in an arc shape. The long slot holes 32 are arc-shaped. The arcs of the plurality of plug holes 31 and the arcs of the long slot holes 32 are concentric with the arc on the fan shape of the tooling frame 3.

[0029] like Figure 1 , Figure 3 As shown, the first locking mechanism 5 includes two latches 51. The two latches 51 are staggered up and down and left and right on the side plate 2. The latches 51 are adapted to the positions of the insertion holes 31.

[0030] like Figure 1 , Figure 5As shown, the second locking mechanism 6 includes a locking member 61, a pressure block 62 and a flange 63. The locking member 61 includes a screw rod 611 and a rotating plate 612 connected to the end of the screw rod 611. The pressure block 62 includes a sliding portion 621 and a locking portion 622 connected to the end of the sliding portion 621. The area of ​​the locking portion 622 is larger than the area of ​​the sliding portion 621, so that the sliding portion can be slidably assembled in the long slot hole 32, and the locking portion 622 is in contact with the surface of the tooling frame 3. A threaded hole is provided on the sliding portion 621. The screw rod 611 passes through the side plate 2 and is threadedly connected to the threaded hole on the sliding portion 621. The rotating plate 612 is placed on the outer side of the side plate 2 away from the tooling frame 3.

[0031] The rotating piece 612 facilitates manual rotation of the screw rod 611 to tighten or loosen the screw rod 611. When the position needs to be adjusted, the screw rod 611 is loosened to loosen the locking portion 622 from the surface of the fixture frame 3. Then the latch 51 is pulled out, and the fixture frame 3 is rotated to a suitable angle. At the suitable angle, the latch 51 is aligned with the socket 31 therein, the latch 51 is installed, and the rotating piece 612 is rotated again to lock the screw rod 611 and the pressure block 62. The locking portion 622 is pulled by the screw rod 611 to make the locking portion 622 close to the surface of the fixture frame 3.

[0032] The positions of the plurality of the jacks 51 determine the specific angle value that the tooling frame 3 can adjust. In this embodiment, the jacks 51 are provided with 2*5 jacks 51, which can be adjusted to any angle between 60° and 90° (e.g. Figure 1 As shown, the positioning surface C is in a vertical 90° state; Figure 2 The positioning surface C shown is in a 60° state), and each 5° angle is an adjustment unit, and is firmly locked by the first locking mechanism 5 and the second locking mechanism 6.
