Problems solved by technology

[0002] At present, when connecting to the small busbar on the screen top of the protective screen cabinet or connecting to the power supply of the equipment, the contact part of the screw is often charged, or it is removed And there is no support in the process of installing the screws. The staff can only use needle-nose pliers or ordinary screwdrivers to clamp the screws and fix the screw positions during work. During the process, problems such as screws falling off and screws not aligning with the screw holes may occur. Reduce the risk of electric shock and short circuit of the secondary line

Abstract

The invention discloses a screwdriver with a fixing clamp. The screwdriver comprises a screwdriver body, a sleeve assembly and a fixing assembly, wherein the screwdriver body comprises a screwdriver handle and a screwdriver head, the screwdriver head is connected with the screwdriver handle, threads are arranged at the tail end of the screwdriver head, the sleeve assembly comprises a hollow sleeve and a connecting rod, the screwdriver body is arranged in the hollow sleeve in a sleeved mode, and the fixing assembly comprises a displacement bolt and a fixing clamp, the displacement bolt is rotationally arranged at the thread position, and the fixing assembly is connected with the sleeve assembly through a connecting rod. According to the screwdriver, through matching of the screwdriver body, the sleeve assembly and the fixing assembly, pre-fixing of a to-be-tightened screw, tightening of the screw and loosening operation of the fixed screw in the tightening process are achieved, the fixing assembly is used for clamping the screw and fixing the position of the screw, and the screw is prevented from falling off due to misoperation when the screw is initially tightened; and meanwhile, the screwdriver body and the fixing assembly are connected through the sleeve assembly, the fixing assembly can be rapidly installed on the screwdriver body or detached from the screwdriver body, and the fixing assembly can be selectively used according to application scene changes.

Description

technical field [0001] The invention relates to the technical field of screwdrivers, in particular to a screwdriver with a fixing clip. Background technique [0002] At present, when connecting to the small busbar on the screen top of the protective screen cabinet or connecting to the power supply of the equipment, because the contact part of the screw is often charged, or there is no support during the process of removing and installing the screw, the staff only Needle-nose pliers or ordinary screwdrivers can be used to pick up the screw and fix the position of the screw. During the process, there may be problems such as the screw falling off and the screw being misaligned with the screw hole. It also increases the risk of electric shock and short circuit of the secondary line. Contents of the invention [0003] The purpose of this section is to outline some aspects of embodiments of the invention and briefly describe some preferred embodiments. Some simplifications or o...
