[0019] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments of the utility model will be clearly and completely described below. Obviously, the described embodiments are partial embodiments of the utility model, rather than all embodiments.

[0020] In the description of the present utility model, it should be understood that the terms "center", "lateral", "longitudinal", "front", "back", "left", "right", "up", "down", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the scope of protection of the present utility model. When a mechanism is referred to as being "fixed to" another mechanism, it may be directly on the other mechanism or there may also be a centered mechanism. When a mechanism is considered to be "connected to" another mechanism, it may be directly connected to the other mechanism or there may be a centered mechanism at the same time. When a mechanism is considered to be "set on" another mechanism, it may be directly set on the other mechanism or there may be a centered mechanism at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0021] like Figures 1 to 4 As shown, the utility model is an adjustable precision tool, comprising: a tool 1, a connecting seat 9, a mounting assembly for mounting the tool 1, an adjusting assembly for adjusting the angle of the tool 1, and a tool head 14 mounted on the connecting seat 9. The angle of the connecting seat 9 is first adjusted by the adjusting assembly, and then the tool head 14 is mounted on the connecting seat 9 by the mounting assembly, so that the angle adjustment of the tool head 14 can be completed, thereby improving the use effect of the tool 1, and when adjusting the angle, the tool head 14 can also be inspected and replaced.

[0022] The adjustment component includes: a worm 2 rotatably connected to the tool 1, a knob 3 fixedly connected to the worm 2, by rotating the knob 3, the worm 2 can be driven to rotate, a worm wheel 4 meshing with the worm 2, the worm wheel 4 is fixedly mounted on a fixed block 7, the worm 2 drives the worm wheel 4 to rotate, so that the angle of the connecting seat 9 rotates, the fixed block 7 rotatably connected to the tool 1, a pointer 8 fixedly mounted on the fixed block 7, the pointer 8 passes through the tool 1 through an arc groove 6, an angle line 5 provided on the tool 1, the angle of the connecting seat 9 can be accurately adjusted through the angle line 5, an arc groove 6 is provided on the tool 1, when the connecting seat 9 rotates, the pointer 8 slides inside the arc groove 6 and points to different positions of the angle line 5, thereby driving the tool head 14 to adjust the angle.

[0023] The user rotates the knob 3, which drives the worm 2 to rotate. The worm 2 drives the worm wheel 4 to rotate by meshing with the worm wheel 4, and also causes the connecting seat 9 to rotate. During this process, the pointer 8 slides inside the arc groove 6 and points to different positions of the angle line 5, so that the user can clearly know the current angle. The user only needs to rotate the knob 3 to stably adjust the angle of the connecting seat 9, and there will be no problem of unstable force and the need to adjust the angle of the cutter head 14 for a long time.

[0024] The installation assembly includes: a positioning groove 11 opened on the connecting seat 9, a positioning block 12 slidably connected to the positioning groove 11, a latch tooth 13 fixedly connected to the positioning block 12, and a bolt 10 threadedly connected to the connecting seat 9. The connecting seat 9 is fixedly connected to the fixing block 7, and a cutter head 14 is fixedly connected to one end of the positioning block 12. The cutter head 14 is inserted into the positioning groove 11 through the positioning block 12, and the latch tooth 13 enters the tooth gap of the worm gear 4. Then, the bolt 10 is used to penetrate the positioning block 12 and the connecting seat 9 from two directions perpendicular to each other to fix them, so as to prevent the cutter head 14 from shaking during use. The latch tooth 13 enters the tooth gap of the worm gear 4, which can prevent accidental rotation and cause the angle of the cutter head 14 to change.

[0025] Working principle:

[0026] Rotate the knob 3 to drive the worm 2 to rotate at the same time. The worm 2 drives the worm wheel 4 to rotate by meshing with the worm wheel 4, and at the same time, the connecting seat 9 rotates. During this process, the pointer 8 slides inside the arc groove 6 and points to different positions of the angle line 5, so that the user can clearly know the current angle. Then the cutter head 14 is inserted into the positioning groove 11 through the positioning block 12, and the locking tooth 13 enters the tooth gap of the worm wheel 4. Then use the bolt 10 to penetrate the positioning block 12 and the connecting seat 9 from two directions perpendicular to each other to fix them.
