[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Please see attached Figure 1 -Attached Figure 4 , a plotter positioning tool, comprising:

[0023] Two groups of clamping jaws 1, a clamping jaw adjustment assembly 2, a connecting block 3, a locking assembly 4 and a telescopic column 5, the two groups of clamping jaws 1 are respectively movably connected to the clamping jaw adjustment assembly 2, a "concave" groove 50 is provided on the upper end of the telescopic column 5, the connecting block 3 is fixedly connected to the clamping jaw adjustment assembly 2, and is rotatably connected to the "concave" groove 50, the locking assembly 4 is fixedly connected to the outer side wall of the "concave" groove 50, and the locking assembly 4 is in contact with the connecting block 3.

[0024] When in use, a mechanical engraving knife or a laser engraving knife can be clamped and fixed by the clamping claw 1. The specific fixing method is as follows: loosen the locking pin 2020 to disengage the lower end of the locking pin 202 from the recessed hole 202, then rotate the turning handle 24, drive the gear 21 to rotate through the connecting rod 23, and then drive the two clamping claws 1 to separate through the L-row toothed plate 22 under the meshing action, so that the engraving knife is located between the two clamping claws 1, and rotate the turning handle 24 again to drive the gear 21, and then complete the fixation of the engraving knife through the clamping claw 1. In order to avoid the misalignment of the two clamping claws 1 In this case, the gear 21 is locked by the locking pin 2020, thereby locking the position of the clamping claw 1. When the angle of the engraving knife needs to be adjusted, the locking plate 40 is pulled outward, and the locking rod 41 is displaced by the locking plate 40 to disengage from the locking hole 31. Then the angle of the connecting block 3 can be freely rotated. After the connecting block 3 and the rectangular shell 20 fixedly connected thereto are turned to a suitable position, the locking plate 40 is released. Under the action of the spring 42, the locking plate 40 is reset, and the locking rod 41 is inserted into the corresponding locking hole 31 again to complete the re-locking of the angle.

[0025] Specifically, the clamping claw adjustment assembly 2 includes a rectangular shell 20, a gear 21, two groups of L-shaped tooth plates 22, a connecting rod 23 and a rotating handle 24. The rectangular shell 20 is provided with two groups of strip-shaped grooves 200 on the side wall close to the clamping claw 1, and a special-shaped cavity 201 is provided on the inner side of the rectangular shell 20. The gear 21 is located in the special-shaped cavity 201. One end of the two groups of L-shaped tooth plates 22 passes through the two groups of strip-shaped grooves 200 and is fixedly connected to the two groups of clamping claws 1, and the other end is slidably connected to the special-shaped cavity 201 and slidably connected to the special-shaped cavity 201. The L-shaped tooth plate 22 in the special-shaped cavity 201 is meshed and connected with the gear 21, one end of the connecting rod 23 is fixedly connected to the turning handle 24, and the other end passes through the rectangular shell 20 and is fixedly connected to the gear 21, and the connecting rod 23 is threadedly connected to the rectangular shell 20; the relative positions of the two groups of L-shaped tooth plates 22 are changed by rotating the gear 21, thereby changing the position of the clamping claw 1 fixedly connected to the L-shaped tooth plate 22, thereby achieving the purpose of clamping the engraving knife, and the setting of the turning handle 24 can directly control the gear 22 from the outside, which is easy to operate.

[0026] Specifically, the rectangular shell 20 is provided with a plurality of recessed holes 202 that match the positions of the turning handle 24, and the turning handle 24 is provided with locking pins 2020 that match the recessed holes 202, and the locking pins 2020 pass through the turning handle 24 and are threadedly connected thereto; considering that in actual applications, the tool may drive the gear 21 to rotate in the reverse direction through the clamping claw 1 during use, the gear 21 can be directly locked by the recessed holes 202 provided on the rectangular shell 20 and the locking pins 2020 that match therewith, so as to avoid the situation where the engraving knife drives the gear 21 to rotate in the reverse direction and causes the engraving knife to loosen and fall. It should be noted that in order to visually see the positions of the recessed holes 202 in the accompanying drawings, the spacing between different recessed holes 202 is relatively far, and the diameter of the recessed holes 202 is relatively large. In actual applications, the arrangement of multiple recessed holes 202 is relatively dense, and the diameter of the recessed holes 202 is very small.

[0027] Specifically, one end of the connecting block 3 is fixedly connected to the side wall of the rectangular shell 20 away from the clamping claw 1, and the other end is rotatably connected to the "concave" groove 50 through a rotating shaft 30, and a plurality of locking holes 31 are provided on the side wall of one end rotatably connected to the "concave" groove.

[0028] Specifically, the locking assembly 4 is located outside the side wall of the "concave" groove 50 close to the locking hole 31, and includes a locking plate 40, at least two sets of locking rods 41 and at least two sets of springs 42. The at least two sets of locking rods 41 are symmetrically positioned through the springs 42 and the side wall of the "concave" groove 50 and are located in the locking hole 31, and the locking rods 41 are slidably connected to the "concave" groove 50, and the two ends of the spring 42 are fixedly connected to the "concave" groove 50 and the locking plate 40 respectively; by locking The hole 31 and the locking rod 41 are arranged to lock the connecting block 3 and the "concave" groove 50, so as to achieve the purpose of controllable rotation angle of the connecting block 3, wherein the arrangement of the spring 42 can ensure that the locking rod 41 is always located in the locking hole 31 under normal conditions, so as to lock the angle of the connecting block 3, and the number of the locking holes 31 is directly related to the angle change of the connecting block 3. The denser the locking holes 31, the smaller the rotation unit of the connecting block 3. For example, if there are only 4 locking holes 31, the connecting block 3 can be fixed again only after rotating 90°.

[0029] Specifically, an angle observation hole 310 is provided on the side wall of the “concave” groove 50 close to the locking hole 31 .

[0030] Specifically, the connecting block 3 is provided with an angle mark 32 corresponding to the locking hole 31 on the side wall of one side of the locking hole 31; in order to facilitate practical application, corresponding angle marks 32 can be set according to the number of locking holes 31, so that during the adjustment process, the staff can observe the angle mark 32 through the angle observation hole 310 to assist in the adjustment of the connecting block 3.

[0031] Specifically, a non-slip pad 10 fixedly connected to the adjacent side walls of the two groups of clamping claws 1 is provided; the non-slip pad 10 can be squeezed by the carving knife during contact with the carving knife to generate friction, thereby achieving its non-slip effect.
