Embodiment Construction
[0017] The present invention is described in detail below through examples, but the present invention is not limited only to the following examples.
[0018] as attached Figure 1-2 As shown, a sleeve for installing self-tapping screws of the present invention includes a sleeve body 1, a bit 2, a base 3, and a support piece 4; the sleeve body includes a first sleeve body 1.1 located at the top And the second sleeve body 1.2 located at the bottom, the two sleeve bodies are connected to each other; the first sleeve body is double-layered, and the inner wall of the inner layer sleeve in the double-layer and the outer circumference of the nut of the self-tapping screw 5 There is a gap and can be used for axial sliding of the self-tapping screw; the interlayer of the double layer is provided with an elastic member (such as a spring) 6 that expands and contracts along the axial direction of the sleeve; the base includes a fixed bit The mounting hole 3.1 and the rib plate 3.2 that c...

The invention discloses a sleeve provided with a self-tapping screw. The sleeve comprises a sleeve body, a screwdriver, a base and support pieces; the sleeve body includes a first sleeve body and a second sleeve body connected with each other; the first sleeve body is set as double layers; the inner wall of the sleeve on the inner layer of the two layers is bonded with the outer periphery of a screw cap of the self-tapping screw, and can enable the self-tapping screw to axially slide; an elastic piece extending in the axial direction of the sleeve is arranged in a sandwich layer arranged between the two layers; the base includes a mounting hole for fixing the screwdriver, and a rib plate capable of sliding up and down along the inner-layer wall of the first sleeve body; a pressure head pressed with the upper end of the elastic part and positioned in the sandwich layer is arranged at the outer end of the rib plate; the support pieces are positioned in the second sleeve body; at least two support pieces are provided; and one ends of the support pieces are fixed on the inner wall of the second sleeve body, and the other ends can swing up and down and are mutually surrounded to form a support base for holding the self-tapping screw. The sleeve has the advantages of guarantee of consistent axis between the screw and the screwdriver, perpendicularity of a screw rod to a mounting surface in the mounting process, no need of disassembly and renewed installation, firm connection and no influence on the mounting efficiency.
Description
technical field [0001] The invention relates to the technical field of self-tapping screw installation tools, in particular to a sleeve for installing self-tapping screws. Background technique [0002] Self-tapping screw is a kind of screw with a drill bit. It is constructed by special electric tools, and drilling, tapping, fixing and locking are completed at one time. During the construction process of the electric tool, it is equivalent to installing a bit on the drill bit of the electric tool, and tapping the screw groove on the upper nut of the self-tapping screw. However, this installation method can only be suitable for shorter self-tapping screws; and when installing longer self-tapping screws with a length between 25 and 45mm, it is difficult for the screw and the bit to keep the central axis consistent, and the installation process leads to The screw rod of the self-tapping screw is not perpendicular to the mounting surface, so it needs to be disassembled and reins...
