It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0026] like Figure 1 to Figure 4As shown, the non-magnetic screw telescopic clamping and assembly device of this embodiment includes an electric screwdriver bit 1, a guide sleeve is fixedly connected to the electric screwdriver bit 1, a chuck 2 is sleeved on the electric screwdriver bit 1, a spring 3 is connected between the chuck 2 and the guide sleeve, and an elastic clamping portion 21 for clamping the non-magnetic screw 7 is provided at the end of the chuck 2, and the elastic clamping portion 21 and the tip of the electric screwdriver bit 1 are located on the same side of the guide sleeve.

[0027] The movable chuck 2 slides toward the tip of the electric screwdriver bit 1 to squeeze the spring 3. The non-magnetic screw 7 is installed into the elastic clamping part 21 of the chuck 2, and the screw head of the non-magnetic screw 7 is clamped by the elastic clamping part 21; and the tip of the electric screwdriver bit 1 matches the groove of the non-magnetic screw 7, so that the non-magnetic screw 7 will not deviate. When the screwing distance between the non-magnetic screw 7 and the mounting surface is short, the elastic clamping part 21 can reliably clamp the non-magnetic screw 7. At this time, when the electric screwdriver bit 1 is rotated to install or remove the non-magnetic screw 7, the non-magnetic screw 7 will not fall off, and it can be operated in a small space.

[0028] The elastic clamping part 21 includes a plurality of clamping pieces arranged along the circumference of the clamping head 2, and there is a gap between adjacent clamping pieces. After the non-magnetic screw 7 is installed into the elastic clamping part 21, the plurality of clamping pieces can clamp the non-magnetic screw 7.

[0029] Specifically, the guide sleeve includes an upper guide sleeve 4 and a lower guide sleeve 5, the upper guide sleeve 4 is fixedly connected to the electric screwdriver bit 1, the upper guide sleeve 4 is fixedly connected to the lower guide sleeve 5, and one end of the chuck 2 away from the elastic clamping portion 21 extends into the lower guide sleeve 5. The lower guide sleeve 5 is provided with a guide notch 51 arranged along the axial direction of the lower guide sleeve 5, and one end of the chuck 2 extending into the lower guide sleeve 5 is threadedly connected with a lever 6, and the lever 6 extends from the guide notch 51. The chuck 2 is pulled to move by the lever 6, which is convenient for operation.

[0030] Furthermore, a limiting notch 52 is provided on the lower guide sleeve 5, and the limiting notch 52 is perpendicular to the axial direction of the lower guide sleeve 5, and the limiting notch 52 is connected to the side of the guide notch 51 close to the elastic clamping portion 21. After the lever 6 is moved to drive the chuck 2 to slide toward the tip of the electric screwdriver bit 1, the lever 6 can be moved to the limiting notch 52 of the lower guide sleeve 5. The limiting notch 52 limits the lever 6, and the chuck 2 cannot slide, thereby preventing the non-magnetic screw 7 from falling out of the elastic clamping portion 21.

[0031] In order to limit the spring 3, a limit platform 22 is provided at one end of the chuck 2 extending into the lower guide sleeve 5, the lever 6 is connected to the limit platform 22, a support platform 53 is provided on the side of the lower guide sleeve 5 away from the upper guide sleeve 4, the spring 3 is located between the limit platform 22 and the support platform 53, and the spring 3 is sleeved on the chuck 2. The spring 3 is sleeved on the chuck 2.

[0032] Specifically, the upper guide sleeve 4 includes a connecting portion 41, on which an upper locking portion 42 and a lower locking portion 43 are respectively provided, the upper locking portion 42 is locked with the electric screwdriver bit 1, and the lower locking portion 43 is locked with the lower guide sleeve 5. The upper locking portion 42 includes two clamping blocks, which are clamped on the electric screwdriver bit 1.

[0033] Installation method:

[0034] Install the upper guide sleeve 4 into the electric screwdriver bit 1 from left to right. First, put the spring 3 and the chuck 2 into the lower guide sleeve 5 from right to left in sequence, and then install them together from left to right into the electric screwdriver bit 1. Lock the lower guide sleeve 5 with the upper guide sleeve 4, adjust the relative position of the chuck 2 and the electric screwdriver bit 1, and then lock the upper guide sleeve 4 on the electric screwdriver bit 1 with a nut, adjust the threaded hole of the chuck 2 to align with the guide notch 51 or the limit notch 52 of the lower guide sleeve 5, and then install the lever 6.

[0035] Working principle:

[0036] Install the non-magnetic screw 7: Move the lever 6 to drive the chuck 2 to slide toward the head of the electric screwdriver bit 1 to squeeze the spring 3. When the lever 6 moves to the limit notch 52 of the lower guide sleeve 5 and is limited, the chuck 2 cannot slide. Install the non-magnetic screw 7 into the chuck 2. The chuck 2 has an elastic clamping part 21. The screw head of the non-magnetic screw 7 is clamped by the elastic clamping part 21 and is centered by the electric screwdriver bit 1 so that it will not deviate. After the non-magnetic screw 7 is screwed into a part of the installation surface, when the lever 6 is moved to the guide notch 51 of the lower guide sleeve 5 without being limited, the chuck 2 is pushed by the spring 3 to slide toward the tail of the electric screwdriver bit 1 to prevent the chuck 2 from contacting the installation surface. The electric screwdriver bit 1 continues to rotate to screw the non-magnetic screw 7 into the installation surface.

[0037] Removing the non-magnetic screw 7: After unscrewing the non-magnetic screw 7 out of a part of the mounting surface, move the lever 6 to drive the chuck 2 to slide toward the head of the electric screwdriver bit 1 to squeeze the spring 3. When the lever 6 moves to the limiting notch 52 of the lower guide sleeve 5 and is limited, the chuck 2 cannot slide, and the screw head of the non-magnetic screw 7 is clamped by the elastic clamping part 21. The electric screwdriver bit 1 continues to rotate to unscrew the non-magnetic screw 7 out of the mounting surface.

[0038] The utility model is suitable for the installation and removal of non-magnetic screws 7 made of stainless steel, copper and other materials. The elastic clamping part 21 of the chuck 2 can be adjusted according to the height of the screw head and locked on the arbor or the electric screwdriver head 1 with a nut. The lever 6 and the spring 3 can quickly lock the relative position of the clamping part and the screwdriver head after the chuck 2 is extended, and can also quickly unlock the chuck 2 to avoid contact with the equipment installation surface after retracting. The method can solve the problem of difficult clamping when installing non-magnetic screws 7 and easy falling when disassembling and clamping non-magnetic screws 7, and achieves the effect of stably clamping the non-magnetic screws 7 without falling off when installing or removing them, and stably retracting the chuck 2 when installing non-magnetic screws 7 without damaging the equipment installation surface. The device can be easily installed on the arbor of a manual screwdriver or the electric screwdriver bit, and can be easily removed when not needed without damaging the tool. It is simple to use and easy to carry.
