Problems solved by technology

[0002] As we all know, screws have been widely used in modern life. The screw-tightening process requires the cooperation of a screwdriver, and the early screwdrivers were all driven by manpower. Later, electric screwdrivers with power input appeared, which greatly improved the screw. Increased speed and strength make screws more widely used. However, the current use of screws still faces some inconveniences that need to be overcome. For example, the screw and screwdriver are only driven by external pressure, and when the pressure disappears, the screw may be separated from the screwdriver. Dropping, some screwdrivers are designed to be magnetic, and the magnetic attraction of the screwdriver to the screw is used to prevent falling. Still produces screw dropouts

Embodiment Construction

[0011] like figure 1 , figure 2 As shown, the present invention is a kind of locking screw bit sleeve, which is provided with a sleeve, the sleeve from top to bottom is a sleeve mouth 2, a sleeve neck 3 and a lower cylinder 1 respectively, and the sleeve is also provided with more than one Deformation seam 6, the deformation seam 6 divides the sleeve neck 2 and the sleeve mouth 2 into several parts, the sleeve neck 3 is sleeved with a sleeve spring 4, the lower cylinder 1 is provided with a fastening bolt 7, the lower cylinder 1 The lower end is connected with a spring 5.

[0012] The deformation seams 6 are evenly distributed with the center axis 2 of the sleeve as the center.

[0013] The sleeve spring 4 is an annular ring with a fracture, has a certain elasticity, and can expand and contract to a limited extent after being stressed.

[0014] When in use, the sleeve spring 4 is sleeved on the sleeve neck 3, the screw to be screwed in is inserted from the lower cylinder 1...

Abstract

The invention discloses a locking screw drill sleeve, which relates to a locking screw drill sleeve. The locking screw drill sleeve is characterized by comprising a sleeve which comprises a sleeve opening, a sleeve neck and a lower cylinder from top to bottom, wherein more than one deformation joints are also arranged on the sleeve; the sleeve neck and the sleeve opening are divided into a plurality of parts by the deformation joints; a sleeve spring is sleeved on the sleeve neck; a fastening bolt is arranged on the lower cylinder; and the lower end of the lower cylinder is connected with a spring. By virtue of the scheme, a screwdriver and a screw are extruded together when the locking screw drill sleeve operates, so that the screw is effectively prevented from accidentally falling off.

Description

technical field [0001] The invention relates to an auxiliary tool for a drill bit, in particular to a locking screw bit sleeve. Background technique [0002] As we all know, screws have been widely used in modern life. The screwdriver is required for the tightening process of screws. In the early days, screwdrivers were driven by manpower. Later, electric screwdrivers with power input appeared, which greatly improved the speed of the screw. The advance speed and force make the application of the screw more extensive. However, the current use of the screw still faces some inconveniences that need to be overcome. For example, the screw and the screwdriver are only driven by external pressure. Falling, some screwdrivers are designed to be magnetic, and the magnetic attraction of the screwdriver to the screw is used to prevent falling. This design has a certain effect, but due to the limited size of the magnetic force, when it is disturbed or the screw quality is large, There a...
