[0022] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0023] The utility model embodiment discloses a self-centering boring head fixture handle.

[0024] The utility model provides Figure 1-4 The self-centering boring head fixture handle shown in the figure comprises a fixture body 1 and a screw rod 2, one end of the screw rod 2 is fixedly connected to the fixture body 1, the rod wall of the screw rod 2 is threadedly sleeved with an internal threaded sleeve 3, the surface of the internal threaded sleeve 3 is movably sleeved with an annular plate 4, four fixed rods 5 are fixedly arranged around the inside of the annular plate 4, and the rod wall of each fixed rod 5 is sleeved with a driving mechanism, four U-shaped plates 6 are arranged around the inside of the annular plate 4, each U-shaped plate 6 is fixedly sleeved with the corresponding fixed rod 5, and a U-shaped block 7 is fixedly arranged on the side wall of each U-shaped plate 6, a first through hole is opened inside each U-shaped block 7, and a push rod 8 is penetrated inside each first through hole , one end of each push rod 8 close to the U-shaped plate 6 is fixedly connected to a connecting plate 9, and two plug rods 10 are fixedly provided on the side wall of the connecting plate 9. Two second through holes are provided inside the U-shaped plate 6, and four plug holes are provided around the side wall of the internally threaded sleeve 3. A plurality of groups of slots are provided around the rod wall of the screw rod 2, and each plug rod 10 is movably connected with the corresponding plug hole and the corresponding slot. The threaded sleeve connection of the internally threaded sleeve 3 and the screw rod 2 can be used to adjust the length of the clamp handle, and after adjustment, the internally threaded sleeve 3 can be limited by the connection between the plug rod 10 and the corresponding slot to avoid relative rotation between the internally threaded sleeve 3 and the screw rod 2.

[0025] like Figure 3-4 As shown, the driving mechanism includes a slider 11 and a push block 12. The slider 11 is movably mounted on the rod wall of the fixed rod 5, and the push block 12 is fixedly arranged on the side wall of the slider 11. A ball 13 is rotatably arranged on the end of the push rod 8, and the ball 13 is in contact and connected with the side wall of the push block 12. The set ball 13 can reduce the friction between the end of the push rod 8 and the side wall of the push block 12, thereby facilitating the movement of the slider 11.
