Specific embodiments

[0018] In order to further understand the content, features and effects of the present invention, the following embodiments are cited and described in detail in conjunction with the accompanying drawings as follows.

[0019] The structure of the present invention will be described in detail below with reference to the accompanying drawings.

[0020] As Figures 1 to 4 shown, a mounting base for a precision repair screwdriver provided by an embodiment of the present invention includes a screwdriver handle 1 and a mounting base 2. The bottom of the screwdriver handle 1 is fixedly connected to the top of the mounting base 2. The bottom of the mounting base 2 is movably connected to a screwdriver bit 3. The surface of the mounting base 2 is movably connected to a control ring 4. One side of the control ring 4 close to the mounting base 2 penetrates through the mounting base 2 and extends into the inner cavity of the mounting base 2. An installation device 5 is arranged inside the mounting base 2.

[0021] Referring to Figure 4 , the installation device 5 includes four installation blocks 501. One side of the installation block 501 away from the control ring 4 penetrates through the mounting base 2 and extends to the outside of the inner cavity of the mounting base 2. One side of the installation block 501 close to the control ring 4 is fixedly connected to a spring 502. One side of the spring 502 close to the inner cavity of the mounting base is fixedly connected to the inner cavity of the mounting base. Two stabilizing blocks 503 are fixedly connected to the surface of the installation block 501. A number of stabilizing frames 504 cooperating with the stabilizing blocks 503 are fixedly connected to the inner cavity of the mounting base 2. The surface of the stabilizing block 503 is movably connected to the inner cavity of the stabilizing frame 504.

[0022] Adopting the above scheme: By setting the installation device 5, when the screwdriver bit 3 moves into the inner cavity of the mounting base 2, the installation device 5 has a limiting effect on the position of the screwdriver bit 3.

[0023] Referring to Figure 3 , four extrusion rotating blocks 6 are movably connected to the inner cavity of the mounting base 2 through a rotating shaft. A moving hole 7 cooperating with the extrusion rotating block 6 is formed on the surface of the installation block 501. The surface of the extrusion rotating block 6 is movably connected to the inner cavity of the moving hole 7.

[0024] Adopting the above scheme: By setting the extrusion rotating block 6 and the moving hole 7, when the extrusion rotating block 6 rotates through the rotating shaft, it can generate an extrusion force on the moving hole 7, and the moving hole 7 subjected to the extrusion force can drive the installation block 501 to move.

[0025] Reference Figure 4 On the surface of the extrusion rotating block 6, an extrusion hole 8 is provided. On the surface of the control ring 4, an extrusion ring 9 that is used in cooperation with the extrusion hole 8 is fixedly connected. The surface of the extrusion ring 9 is movably connected to the inner cavity of the extrusion hole 8.

[0026] With the above solution: By providing the extrusion hole 8 and the extrusion ring 9, when the control ring 4 moves, it will drive the extrusion ring 9 to move along the inner cavity of the extrusion hole 8. The extrusion force generated by the extrusion ring 9 on the extrusion hole 8 can drive the extrusion rotating block 6 to rotate through the rotating shaft.

[0027] Reference Figure 3 At the bottom of the inner cavity of the mounting seat 2, two limiting rods 10 are fixedly connected. On the surface of the control ring 4, two limiting holes 11 that are used in cooperation with the limiting rods 10 are provided. The surface of the limiting rod 10 is in contact with the inner cavity of the limiting hole 11.

[0028] With the above solution: By providing the limiting rods 10 and the limiting holes 11, when the control ring 4 moves, it will drive the limiting holes 11 to move along the surface of the limiting rods 10. The cooperation of the limiting holes 11 and the limiting rods 10 has a limiting effect on the moving position of the control ring 4.

[0029] Reference Figure 2 On the surface of the screwdriver bit 3, four mounting grooves 12 that are used in cooperation with the mounting blocks 501 are provided. The surface of the mounting block 501 is in contact with the inner cavity of the mounting groove 12.

[0030] With the above solution: By providing the mounting grooves 12, when the screwdriver bit 3 moves into the inner cavity of the mounting seat 2 and the control ring 4 is released, the restoring force generated by the spring 502 restoring its shape will drive the mounting block 501 to snap into the inner cavity of the mounting groove 12. The cooperation of the mounting block 501 and the mounting groove 12 has a limiting effect on the position of the screwdriver bit 3.

[0031] Reference Figure 2 On both the left and right sides of the screwdriver bit 3, two docking rods 13 are fixedly connected. At the bottom of the mounting seat 2, two docking shells 14 that are used in cooperation with the docking rods 13 are fixedly connected. The surface of the docking rod 13 is in contact with the inner cavity of the docking shell 14.

[0032] With the above solution: By providing the docking rods 13 and the docking shells 14, when the screwdriver bit 3 moves, it will drive the docking rods 13 to move into the inner cavity of the docking shells 14. The cooperation of the docking rods 13 and the docking shells 14 has a limiting effect on the position where the screwdriver bit 3 moves into the inner cavity of the mounting seat 2.

[0033] During use, when the mounting base 2 of the precision screwdriver needs to conveniently and stably install the screwdriver bit 3, first, the user pulls the control ring 4 upwards. When the control ring 4 moves, it will drive the limit hole 11 to move along the surface of the limit rod 10. When the control ring 4 moves, it will drive the extrusion ring 9 to move along the inner cavity of the extrusion hole 8. The extrusion hole 8 under the extrusion force will drive the extrusion rotating block 6 to rotate along the inner cavity of the moving hole 7 through the rotating shaft. The extrusion force generated by the extrusion rotating block 6 on the moving hole 7 will drive the installation clamping block 501 to move towards the side close to the control ring 4. When the installation clamping block 501 moves, it will drive the stable clamping block 503 to move along the inner cavity of the stable frame 504. When the installation clamping block 501 moves, the force generated causes the spring 502 to undergo elastic deformation. When the installation clamping block 501 completely moves into the inner cavity of the mounting base 2, move the docking rod 13 into the inner cavity of the docking shell 14, and at the same time drive the screwdriver bit 3 into the inner cavity of the mounting base 2. Then release the control ring 4. The restoring force generated when the spring 502 resumes its shape will drive the installation clamping block 501 to snap into the inner cavity of the installation groove 12. The cooperation of the installation clamping block 501 and the installation groove 12 has a limiting effect on the position of the screwdriver bit 3. At this time, the mounting base 2 of the precision screwdriver needs to complete the convenient and stable installation of the screwdriver bit 3.

[0034] In summary: For the mounting base of this precision screwdriver, by setting up the cooperation of the installation device 5, the installation clamping block 501, the spring 502, the stable clamping block 503 and the stable frame 504, it solves the problem that when installing the screwdriver bit of the existing precision screwdriver, it needs to be installed on the mounting base set on the screwdriver handle in corresponding ways. There are various installation methods for the screwdriver bit, such as magnetic adsorption type, plug-in type, screw installation type, etc. Relying on magnetic adsorption installation will cause the magnetic force to weaken over time, resulting in unstable installation of the screwdriver bit. The plug-in type is prone to wear of the screwdriver bit after frequent use, and the bolt installation takes a long time and is not convenient enough. However, the existing mounting base of the precision screwdriver does not have components for conveniently and stably installing the screwdriver bit.
