DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0025] Please refer to Figure 1-5 ;

[0026] The adjustable tool handle of the present invention is intended to reduce the influence of vibration generated during the machining process on the adjusting ring 3. First, the structure of the tool handle is described. It specifically includes a tool handle main body base 1. A back cover 2, an adjusting ring 3, a chuck meson 4 and a chuck sleeve 5 are sequentially installed in the tool handle main body base 1. It should be noted that a coaxial channel is formed in the back cover 2, the adjusting ring 3, the chuck meson 4 and the chuck sleeve 5. When in use, a chuck is provided in the channel, and the chuck is used to fix the tool; a plurality of fixing components 6 are inserted into the side of the tool handle main body base 1 for adjusting and fixing the adjusting ring 3 so that the chuck reaches the most stable state;

[0027] The fixing assembly 6 is further described, specifically including an adjusting nut 61 and a fixing nut 62. In this embodiment, a through hole adapted to the adjusting nut 61 should be provided on the base 1 of the handle body, so that the adjusting nut 61 is passed into the base 1 of the handle body, and the adjusting nut 61 is threadedly connected with an adjusting screw 63. One end of the adjusting screw 63 extends into a card slot 31 on the side wall of the adjusting ring 3. Different adjusting screws 63 are clamped with the adjusting ring 3, so that the position of the adjusting ring 3 can be limited; the fixing nut 62 is connected to the base 1 of the handle body. 1 is threadedly connected, and its bottom is against the upper end of the adjusting nut 61. Preferably, a through hole for the adjusting screw 63 to pass through is provided in the fixing nut 62. When adjustment is required, the adjusting screw 63 can be turned without removing the fixing nut 62. The fixing nut 62 adopts a cross wrench design to achieve greater locking force and higher stability. A second Kimi screw 64 is also threadedly connected to the base 1 of the handle body. The end of the second Kimi screw 64 is against the outer wall of the adjusting nut 61. Specifically, the second Kimi screw 64 is distributed at 90° with the adjusting nut 61.

[0028] When the position of the adjusting ring 3 needs to be adjusted, all adjusting screws 63 are loosened, and then the corresponding adjusting screws 63 are rotated according to the position that needs to be adjusted to contact the adjusting ring 3, and the adjusting ring 3 is pushed to adjust the position. After completion, all adjusting screws 63 are tightened to contact the adjusting ring 3 to limit the position. This is a conventional adjustment process; and the vibration generated by the tool handle during operation will affect the adjusting nut 61. In this embodiment, the adjusting nut 61 is locked by locking the second base screw 64, and the second base screw 64 contacts the adjusting nut 61 and generates a lateral resistance force, locking or fixing the adjusting nut 61 to prevent the adjusting nut 61 from rotating. At the same time, the fixing nut 62 applies a longitudinal resistance force to the adjusting nut 61 to prevent the adjusting nut 61 from moving longitudinally. The utility model provides two fastening methods for the adjusting nut 61 so that it does not happen now, and the stability is better.

[0029] Preferably, a Kimi screw 65 is threadedly connected to the base of the handle body 1, and the end of the Kimi screw 65 is against the outer side of the fixing nut 62. The lateral resistance force provided by the Kimi screw 65 can prevent the fixing nut 62 from rotating, thereby further improving stability. Preferably, a copper pin thread insert is added between the Kimi screw 65 and the fixing nut 62 to protect the outer teeth of the fixing nut 62.

[0030] Furthermore, the outer side of the adjusting nut 61 extends laterally to form a step 68 , and a receiving space 69 is provided in the fixing nut 62 . The upper end of the adjusting nut 61 is placed in the receiving space 69 , and the step 68 abuts against the lower end surface of the fixing nut 62 .

[0031] In the embodiment of the present invention, an adjusting washer 66 is provided in the first card slot 31, and the adjusting screw 63 passes through the adjusting washer 66. The adjusting washer 66 can prevent the adjusting screw 63 from colliding with the inner wall of the first card slot 31. Preferably, the adjusting washer 66 is fixed on the adjusting screw 63 and moves with the adjusting screw 63.

[0032] In addition, a protruding pipe position 67 is provided at the bottom of the adjusting washer 66 , and a locking position 32 used in conjunction with the protruding pipe position 67 is provided at the bottom of the locking groove 31 to prevent the adjusting washer 66 from rotating.

[0033] In the embodiment of the present utility model, a fixing screw 7 is threadedly connected to the base 1 of the tool handle body, and the fixing screw 7 passes through the base 1 of the tool handle body and extends to the second slot 51 on the outside of the chuck sleeve 5. The position of the chuck sleeve 5 is limited by the fixing screw 7 to prevent the chuck from being pushed out under the repeated force of tightening and disassembling the knife in the working state.

[0034] In the embodiment of the present utility model, a mounting groove 33 is provided in one end of the adjusting ring 3, and a plurality of arc grooves 34 are provided in a circular array on the inner side wall of the mounting groove 33. In one embodiment, a plurality of arc convex strips are provided in the reversing array on the inner side wall of the mounting groove 33, and an arc groove 34 is formed on both sides of the arc convex strip, that is, the plurality of arc grooves 34 are adjacently arranged, and the chuck meson 4 is placed in the mounting groove 33, and a plurality of spring ball assemblies 41 are provided on the side wall of the chuck meson 4. Of course, a plurality of mounting positions are provided on the side wall of the chuck meson 4 for accommodating the spring ball assemblies 41. Preferably, the spring ball assemblies 41 have three groups, which are distributed at 120°, so as to provide stable and balanced support for the circumference of the chuck meson 4. The spring ball assemblies 41 are engaged with the arc grooves 34, and the number of arc grooves 34 is greater than that of the spring ball assemblies 41, and they are usually arranged in multiples.

[0035] When the chuck is assembled in the inner hole, it rotates, and the chuck meson 4 also rotates synchronously to play a positioning role. A plurality of arc grooves 34 are formed in a grid-like manner. After the chuck is assembled to the bottom, it is possible to understand the angle of rotation by rotating it backward. After the adjusted position is fixed, the ball is pushed to the bottom of the arc groove 34 by the action of the spring. The spring has a large thrust, so it cannot be compressed without reaching the preset torque, that is, the chuck meson 4 cannot rotate, thereby playing a positioning role and will not be loose in the working state.

[0036] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
