Problems solved by technology

However, in precision electronic devices, due to the consideration of electrical performance and physical characteristics, copper screws are mostly used, and magnets have no adsorption effect on them; moreover, insulating partitions are often installed at the backplane wiring of such devices, and The wiring is dense and may even be electrified, and it is difficult to support it by hand. In this case, the possibility of screw dropping is greatly increased. There is no effective solution at present

Embodiment Construction

[0017] Refer to attached figure 1 Make the invention. The screwdriver clamping anti-drop sheath is characterized in that it includes a clamping sheath 3 , and an opening 5 is provided on the front end wall of the clamping sheath 3 .

[0018] The rear end of the clamping sheath 3 is fixedly connected to the buckle 1 through the spring 2 .

[0019] The buckle 1 is cylindrical, and the side wall of the buckle 1 is divided into two layers, the outer layer is a plastic layer, and the inner layer is a soft rubber layer, which plays an anti-slip effect. The length of the buckle 1 is 0.8 times the diameter, and the buckle 1 The inner diameter of 1 is slightly smaller than the diameter of the screwdriver shank, and there is a middle slit 4 in the axial direction of the side wall of the buckle 1, which can make it produce a small elastic deformation. The whole device is fixed on the screwdriver bar.

[0020] The spring 2 is made of metal, the inner diameter is slightly larger than th...

Abstract

The invention discloses a clamping and drop-preventing sheath for a screwdriver. The clamping and drop-preventing sheath is characterized by comprising a clamping sheath, wherein an opening is formed in the front end wall of the clamping sheath; and the rear end of the clamping sheath is fixedly connected with a buckle through a spring. The clamping and drop-preventing sheath is simple in structure, low in cost and easy to mount, can be used by matching with any ordinary screwdriver, and prevents screws from falling off in a screw loading / unloading process, so that the working efficiency and the mounting quality are improved.

Description

[0001] technical field [0002] The invention relates to an auxiliary device for a screwdriver, in particular to a clamping and anti-drop sheath for a screwdriver. [0003] It is a small accessory installed on an ordinary screwdriver. It can prevent the screw from falling during the installation / removal of the screw, and avoid the time and economic loss caused by repetitive work. It is widely used in various occasions such as daily life and engineering sites. Background technique [0004] Screwdriver is a tool that is often used in people's production and life. In the process of use, it is often encountered that the screws accidentally fall off. At this time, first of all, it will bring repetitive work, resulting in a waste of time; and if it is on a project site with a chaotic environment, the screws may fall in the messy environment, such as grass, cable trenches, and pebbles under the transformer, resulting in Unable to retrieve; Especially for some screws with special ...
