Abstract
The invention discloses a screw driver assist device. The screw driver assist device achieves fixations of a screw driver and screws through a screw driver fixing device and a screw fixing device, and simultaneously the screw driver fixing device and the screw fixing device are both of cylindrical structure, and can slide relatively to each other. When the screws are loosened, the screws can be continuously moved out of the screw fixing device, and finally removal of the fixation of the screws is achieved. Compared with a traditional magnetic type screw fixation, the fixations achieved by the screw driver assist device are good in stability and screwing directionality.
Description
Technical field
The present invention relates to a kind of screwdriver aid, belong to field of tool.
Background technology

Summary of the invention
The object of the invention is to: a kind of screws clamp device that can be fixed on screwdriver is provided.
The present invention realizes in the following way:
A kind of screwdriver aid, described assistor comprises screw fixator and screwdriver fixator, and described screw fixator and screwdriver fixator are cylinder-like structure, and it is outside that described screw fixator is slidably socketed in screwdriver fixator;
Described screwdriver fixator comprises lock sleeve and adapter sleeve, described adapter sleeve is hollow cylinder, described adapter sleeve adopts elastomeric material to make, described adapter sleeve one end is inserted into screwdriver fixator cylinder, the circumferential inner wall of described adapter sleeve be provided with at least one the adapter sleeve other end end face opening and axially extend and the elongated hole of through adapter sleeve circumferential inner wall, the elongated hole section surface of described adapter sleeve is processed with external screw thread, described lock sleeve inwall is processed with the internal thread corresponding with described external screw thread, lock sleeve and adapter sleeve are threaded connection, the diameter of the inwall of described adapter sleeve is more than or equal to the diameter of screwdriver,
Described screw fixator comprises screw clip and screw fixator shell, described screw clip comprises some elastic bumps being fixed on screw fixator outer casing inner wall, and the height of projection that the radius of described screw fixator outer casing inner wall deducts described elastic bumps is less than the radius of head of screw;
Wherein one end of described screw fixator shell is provided with towards the annular protrusion A in axle center, the internal diameter of described annular protrusion A is greater than the external diameter of adapter sleeve, one end end face that described adapter sleeve is inserted into screw stationary cylinder is provided with towards the annular protrusion B of adapter sleeve outside, and the external diameter of described annular protrusion B is less than the internal diameter of screw fixator shell;
The outside wall surface of described annular protrusion A and adapter sleeve is slidably connected, and the internal face of described annular protrusion B and screw fixator shell is slidably connected.
As further innovation of the present invention, described elastic bumps is the elastic metallic yarn being fixed on screw fixator outer casing inner wall face of some annular array types, described elastic metallic yarn has a bending angle, and described elastic metallic yarn bending angle top is the height of projection of elastic bumps to the distance in screw fixator outer casing inner wall face.
As further innovation of the present invention, described lock sleeve one end is provided with the annular protrusion C towards lock sleeve axle center, and the internal diameter of described annular protrusion C is greater than the external diameter of screwdriver and is less than the external diameter of lock sleeve.
Beneficial effect:
The present invention fixes while realizing screwdriver and screw by the screw fixing device of a screwdriver fixture and a spring, screwdriver fixture simultaneously in the present invention and screw fixing device can movements mutually, can lock by automatic lift after screw is screwed into completely, more stable compared to the screw fixing means of traditional magnet-type, can not drop because of touching or vibration, there is good practicality.
Accompanying drawing explanation
Fig. 1 is the generalized section of invention.
Fig. 2 is use schematic diagram of the present invention.
In figure: 1, screw fixator shell; 2, elastic metallic yarn; 3, adapter sleeve; 4, annular protrusion A; 5, annular protrusion B; 6, lock sleeve; 7, elongated hole; 8, annular protrusion C; 9, screwdriver; 10, head of screw.
Detailed description of the invention
Be described further below in conjunction with accompanying drawing:
As shown in Figure 1 and 2, the present invention includes screw fixator shell 1, adapter sleeve 3, lock sleeve 6, the circumferential inner wall of described adapter sleeve 3 is provided with four at the end face opening of adapter sleeve one end and axially extends and the elongated hole 7 of through adapter sleeve 3 circumferential inner wall, the outside wall surface that described adapter sleeve 3 is provided with elongated hole 7 is also processed with external screw thread, described lock sleeve 6 is cylinder-like structure, and inside is provided with the internal thread corresponding with described external screw thread, the fixing of screwdriver 9 is realized by internal thread and externally threaded occlusion, described lock sleeve 6 one end is provided with the annular protrusion C8 for limiting lock sleeve 6 shift motion, the other end of described adapter sleeve 3 is provided with annular protrusion B5, one end of described screw fixator shell 1 is provided with annular protrusion A4, between described adapter sleeve 3 and screw fixator shell 1 by the internal face of annular protrusion B5 and screw fixator shell 1 be slidably matched and annular protrusion A4 to realize with the cooperation of the outside wall surface of adapter sleeve 3 both slide over each other and be connected, the inside of described screw fixator shell 1 also annular permutation be placed with some elastic metallic yarns 2, described elastic metallic yarn 2 has a protruding angle, described screw fixator realizes the fixing of head of screw 10 by this protruding angle,
Lock sleeve 6 is first unscrewed during use, screwdriver 10 is inserted in adapter sleeve 3, to operate head, all to stretch out adapter sleeve 3 be suitable to screwdriver 10, screw lock sleeve 6 afterwards and realize the fixing of screwdriver 10, then screw is inserted into screw fixator inside, realize the fixing of screw by elastic metallic yarn 2, finally screw is screwed into workpiece;
When being screwed into, because the screw thread of screw constantly shortens, surface of the work promotes screw fixator shell 1 and moves backward, until adapter sleeve 3 extend out to concordant with the end face of screw fixator shell 1, realize being screwed into of screw, compared to traditional magnetic attachment type screw driver, this instrument is more for the contact surface of screw, so more stable, and can ensure that the thing being vertically screwed into anti-on-slip tooth of screw occurs.
