[0027] In this embodiment, the fastening component 2 is configured to be annular, and the fastening component 2 is annularly fitted inside the back-shaft chuck body 1, so that it can fit more closely inside the chuck to avoid falling off.

[0028] In this embodiment, a cutout groove 101 is fixedly provided on the outside of the back-shaft chuck body 1. The cutout groove 101 is arranged in a circular ring shape, which can better fix various tools clamped in the back-shaft chuck.

[0029] When using the back-shaft chuck body 1, the user puts the clamped tool into the back-shaft chuck body 1. When the tool passes through the fastening component 2 set inside the back-shaft chuck body 1, the tool squeezes the fixed block 201 set on the fastening component 2 inside the back-shaft chuck body 1. Under the action of the anti-slip gasket 202, the damper 204 and the outer spring 203 are pushed. The spring 203 provides elastic potential energy to push the anti-slip gasket 202 to quickly reset after the external force is lost.

[0030] Example 2

[0031] like Figure 3-4 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes a back-shaft chuck, a cleaning component 3 is slidably arranged inside the back-shaft chuck body 1, the cleaning component 3 includes a cleaning rubber ring 301 fixedly connected inside the cleaning component 3, a gripping clamp 302 is arranged on the outer side of the cleaning rubber ring 301, and the gripping clamp 302 is fixedly connected to the cleaning rubber ring 301, and a threaded groove is opened inside the gripping clamp 302, a hand handle 303 is threadedly connected to the left side of the gripping clamp 302, and a sewage outlet 304 is fixedly connected to the upper part of the gripping clamp 302.

[0032] In this embodiment, the cleaning rubber ring 301 is set to be ring-shaped, the material of the cleaning rubber ring 301 is set to be rubber material, and it is tightly fitted inside the back shaft chuck body 1, so that it can fit more closely inside the chuck.

[0033] In this embodiment, one side of the hand-pull handle 303 is configured to be spirally shaped, and the hand-pull handle 303 is spirally connected to the inside of the grasping clamp 302, so that the grasping clamp 302 can adjust the opening size of the grasping clamp 302 more quickly.

[0034] In this embodiment, the drain outlet 304 is set to a mouth shape, and the drain outlet 304 is fixedly connected to the gripping clamp 302. A baffle is fixedly set above the drain outlet 304, which can make the drain outlet 304 more convenient to discharge the residual chip residues in the back-shaft chuck and prevent the residual chip residues from causing the surface of the parts to be clamped. The fixed baffle above the drain outlet 304 can prevent the chip residues from falling into the drain outlet during cleaning.

[0035] Before using the new back-shaft chuck, the user places the cleaning component 3 inside the back-shaft chuck, rotates the hand handle 303, and rotates the thread on one side of the hand handle 303 to tighten the gripping clamp 302. By adjusting the opening size of the gripping clamp 302, the gripping clamp 302 squeezes and tightens the cleaning rubber ring 301 to achieve a suitable size. After adjusting to the suitable size, the hand handle 303 is pulled up and down inside the back-shaft chuck, and various chips and residues remaining inside the back-shaft chuck are discharged through the drain port 304.

[0036] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
