A screwdriver with slotting function and using method thereof

Abstract

The invention provides a screwdriver with a slotting function and a using method thereof, and belongs to the field of screwdrivers. The screwdriver solves the problem of low efficiency of slotting operation of an existing screwdriver. The screwdriver with the slotting function comprises a screwdriver shank and a screwdriver rod; the front end and the rear end of the screwdriver rod are provided with a main screwdriver head and a sub screwdriver head, a rod hole is arranged in the screwdriver shank, the screwdriver rod penetrates into the rod hole, and the front end hole wall of the rod hole isprovided with an inner adjusting groove; an inner adjusting sleeve located in the inner adjusting groove is included, the outer wall of the inner adjusting sleeve is provided with an adjusting surface and a screwing surface, and the outer wall of the front end of the screwdriver shank is provided with an outer adjusting groove; an outer adjusting sleeve with the back end arranged on the outer adjusting groove in a sleeving manner is further included, a sliding groove is arranged in the groove wall of the outer adjusting groove, the inner wall of the outer adjusting sleeve is provided with a slider, and the inner wall of the front end of the outer adjusting sleeve is provided with an internal thread; and a rotating shaft with the two ends fixed to the sleeve wall of the inner adjusting sleeve is further included, and the middle portion of the rotating shaft is arranged on the screwdriver rod in a penetrating manner; and a stopping sleeve with the back end fixedly provided with a baffleis further included, and notch grooves are formed in the sleeve walls on the two sides of the front end of the stopping sleeve. According to the screwdriver, after a screw groove is abraded, a screwcan be unscrewed efficiently, stably and conveniently.

Description

technical field [0001] The invention belongs to the technical field of screwdrivers, and relates to a screwdriver with a slotting function and a using method thereof. Background technique [0002] When the traditional screwdriver removes the screw, it is necessary to apply additional force to prevent the screwdriver bit from slipping off the thread groove. If the force is not enough, it will cause slippage. The existing application number is 201710332608.8, and the name is "an improved multi-functional screwdriver and Its method of use” Chinese invention patent, although it can use the auxiliary cutter head to make additional grooves on the thread groove to assist in unscrewing the screw when the screw cannot be opened after the thread slips. However, when it is used in practice, the following problems still exist: [0003] 1. Since the auxiliary cutter head needs to move back and forth along the inline direction to make the groove when it grooves on the thread groove, so t...

AI Technical Summary

Problems solved by technology

[0003] 1. Since the auxiliary cutter head needs to move back and forth along the inline direction to make the groove when it grooves on the thread groove, so through the cooperation of the rolling ball and the ball groove, it is impossible to make the cutter rod rotate around the center of the rolling ball to perform the groove stably.

[0004] 2. Although the position of the connecting plate can be adjusted through the cooperation of the connecting sleeve and the connecting groove, so that the blade can adapt to the depth of the wire groove, but it can be known from the above that it needs to move back and forth along the straight direction for slotting, and because the connecting sleeve and the connecting groove are Thread fit, so when slotting on the wire slot, the connecting sleeve is very easy to move around the axis of the connecting slot, resulting in unstable slotting process

[0006] 4. Regardless of whether the retaining sleeve is installed at the front end or the rear end of the tool rod, it cannot fix the retaining sleeve relative to the circumferential direction of the tool rod, so it is very easy to make the retaining sleeve rotate around the tool rod. The axis rotates, the operation is very troublesome and the stability is poor
