Embodiment one:
referring to fig. 1 and 2, a screwdriver with a spring holder includes a screwdriver shaft 10 and a screwdriver head 11.
The screwdriver rod 10 is provided with a spring positioning sleeve 21, and the spring positioning sleeve 21 is a lantern ring fixedly arranged on the screwdriver rod. In this embodiment, the spring positioning sleeve is a metal ring, and the spring positioning sleeve can be fixed on the screwdriver rod by various means, such as fixing by a jackscrew, fixing by a pin shaft, or directly welding on the screwdriver rod.
The screwdriver rod 10 is sleeved with a compression spring 20, and a screw clamping frame 30 is further arranged on the screwdriver rod.
The compression spring 20 is arranged on the side of the screwdriver rod facing away from the spring positioning sleeve 21.
The screw holding frame 30 is formed by bending a steel plate strip with the thickness of 1 mm. The screw clamping frame is provided with a rear sliding frame 31 and a front clamping frame 32, the rear sliding frame is provided with a sliding frame hole 33 which is in sliding fit with the screw cutter bar, the front clamping frame is provided with a screw clamping groove 34, the compression spring 20 is arranged between the spring positioning sleeve 21 and the rear sliding frame 31, and the two ends of the compression spring respectively press against the spring positioning sleeve and the rear sliding frame, so that the front clamping frame 32 can elastically press against the screw cutter head. The screw clamping groove 34 of the front clamping frame corresponds to a screw design, can be embedded into a screw rod 41 and clamps a post screw cap 42.
A fit clearance is provided between the carriage hole 33 and the screwdriver rod to enable the screw holder 30 to tilt relative to the screwdriver rod so that the front holder is axially displaced from the screwdriver rod 10, as shown in fig. 8 and 9. In this embodiment, the screw driver rod with a diameter of 6mm and the carriage hole with a diameter of 6.5mm are adopted, so that the front clamping frame can easily separate from the screw driver rod in the axial direction, and the pressing action of the compression spring 20 on the screw clamping frame 30 is not affected.
This embodiment exemplifies a cross-head screwdriver and cross-head screw.
In the screw tightening operation, the screw holder 30 is pushed forward (toward the driver bit) to disengage the front holder 32 from the driver bit 11, the nut 42 is inserted into the driver bit 11, and the screw shaft 41 is inserted into the screw holding groove 34, as shown in fig. 5.
Then the screw clamping frame 30 is loosened, the compression spring 20 pushes the rear sliding frame 31 of the screw clamping frame, the screw clamping frame 30 moves backwards under the action of the elastic thrust of the compression spring 20, the front clamping frame 32 pushes the screw cap 42 against the screwdriver head, and the screw is stably kept on the screwdriver head and cannot fall off easily, as shown in fig. 6.
Thereafter, a screw may be screwed into the body 50 using a screwdriver, as shown in fig. 7.
After the screw is firmly inserted into the body 50, the screw holder 30 can be pushed forward again (or the screw driver shaft 10 can be pulled backward) and the holder 32 can be separated from the screw obliquely, as shown in fig. 8.
Finally the screw is tightened on the body as shown in fig. 9.
The screw can be effectively prevented from falling off the screwdriver, the operation is convenient, and the safety of equipment can be ensured.
