Accompanying drawing explanation
Fig. 1 is the structural representation of the clamping device of the utility model embodiment.
Detailed description of the invention
For enabling above-mentioned purpose of the present utility model, feature and advantage become apparent more, are described in detail detailed description of the invention of the present utility model below in conjunction with accompanying drawing.Set forth a lot of detail in the following description so that fully understand the utility model.But the utility model can be much different from alternate manner described here to implement, those skilled in the art can when doing similar improvement without prejudice to when the utility model intension, and therefore the utility model is by the restriction of following public concrete enforcement.
As shown in Figure 1, the clamping device 1 that the present embodiment provides, for screw 2 being fixed on the screwdriver bit 3 of screwdriver, clamping device 1 comprises the first hold assembly, the second hold assembly, sleeve pipe 11, locking member 12 and attaching parts.First hold assembly comprises at least two the first jaws 111, and in the present embodiment, the first hold assembly comprises three the first jaws 111, and the first jaw 111 is for having flexible first clamping plate sheet, and described first jaw 111 is for clamping described screw 2.In addition, the first stiff end 132 and the second stiff end that attaching parts comprise protuberance 131, extend out from the both sides of protuberance 131 respectively, and attaching parts inner hollow, as can be known from Fig. 1, second hold assembly and attaching parts one-body molded, therefore, in the present embodiment, the second stiff end is the second jaw 121.In another embodiment, the second jaw 121 is connected with the second stiff end by screw.
One end of first jaw 111 is screwed on the first stiff end 132 of attaching parts, and three the first jaws 111 form the first cavity, is being fixed on by screw 2 in screwdriver bit 3 process, screw 2 can be being stretched in this first cavity.The first hold assembly that first jaw 111 forms has the end face of opening, i.e. the end face of the opening of the first cavity.
In addition, sleeve pipe 11 is moving casing, it is sheathed on the first hold assembly, and sleeve pipe 11 can slide on the first hold assembly, the diameter due to sleeve pipe 11 be less than the diameter of the end face of the opening of the first cavity and the first jaw 111 flexible, therefore, when the side at attaching parts place shifted to by sleeve pipe 11, the first jaw 111 opens, and when the side of opposing connections part shifted to by sleeve pipe 11, the opening of the first cavity that sleeve pipe 11 forces the first jaw 111 to be formed reduces, thus clamps screw 2.
The second hold assembly for clamping screwdriver bit 3 comprises at least two the second jaws 121, in the present embodiment, second hold assembly comprises four the second jaws 121, and the second jaw 121 is for having flexible second clamping plate sheet, four the second jaws 121 form the second cavity together with the cavity connects of attaching parts, and described second cavity and described first cavity connects.
Screw 2 is being fixed in the process of screwdriver bit 3, screwdriver bit 3 is stretched into the second cavity, with the screw 2 phase top of the first cavity, known by above-mentioned description, by adjustable first jaw 111 of sleeve pipe 11, thus screw 2 is clamped, and the second jaw 121 clamps screwdriver bit 3 by rotational lock parts 12.Particularly, locking member 12 is cavity structure, locking member 12 is sheathed on the outside of the second jaw 121, the inwall of one end of locking member 12 is provided with internal thread, second jaw 121 is provided with the external screw thread with screw-internal thread fit, thus by rotating, locking member 12 can be connected with the second jaw 121, and there is elasticity due to the second jaw 121, and the other end of locking member 12 is along the direction away from described internal thread, diameter diminishes gradually, namely away from the direction of internal thread, the shape of the other end of locking member 12 is round platform, and diameter diminishes gradually.When rotating, locking member 12 applies active force to the second jaw 121, therefore can reduce the size of the opening of the second cavity, thus is clamped by screwdriver bit 3.Therefore, by clamping device 1, screw 2 is fixed on screwdriver bit 3, and the center line of screw 2 and the center line of screwdriver bit are consistent, the position of screw 2 can keep fixing, when screw 2 is especially installed in narrow space, the problem of screw 2 off normal not easily causing screw 2 to drop or install.
Above-mentioned clamping device 1, when installing screw 2, first the screwdriver bit 3 of screw 2 and screwdriver is aimed at, screw 2 is through the first cavity, screwdriver bit 3 is through the second cavity and the first cavity, slided on the first jaw 111 by sleeve pipe 11, and the diameter being fixed on the end face of the outer openings of the first jaw 111 on the side of attaching parts is greater than the diameter of sleeve pipe 11, thus during sliding sleeve 11, first jaw 111 can clamp screw 2, in addition, the second jaw 121 be fixed on the opposite side of attaching parts clamps screwdriver bit 3, the inwall of one end of locking member 12 is provided with internal thread, and the second jaw 121 is provided with the external screw thread with this screw-internal thread fit, thus locking member 12 can be connected with the second jaw 121, and the other end of locking member 12 is truncated conical shape, during rotational lock parts 12, second jaw 121 can clamp screwdriver bit 3, thus screw 2 is fixed on screwdriver bit 2, the position of screw 2 keeps fixing, the problem of screw 2 off normal not easily causing screw 2 to drop or to install.
The above embodiment only have expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
