The specific embodiment
The present invention reaches above-mentioned object and effect, and the technological means adopting and structure, and hereby collocation diagram is described in detail its feature and effect with regard to embodiments of the invention.
Shown in Fig. 1 to Fig. 5, a kind of instrument clamping device of the present invention, it comprises an adapter 1 and an elastic clamp ring 2, wherein: this adapter 1 is provided with a fixing slot 11, these fixing slot 11 inwalls cut open establishes the first spacing raceway groove 12 and the second spacing raceway groove 13 (the spacing raceway groove 12 of the present embodiment first and the second spacing raceway groove 13 are positioned at and are oppositely arranged), and is provided with one first spacing hole 111 in the first spacing raceway groove 12; This elastic clamp ring 2 is mounted on fixing slot 11, this elastic clamp ring 2 shape that takes the shape of the letter U, and elastic clamp ring 2 comprises that a linkage section 21 and is positioned at first butted section 22 of the first spacing raceway groove 12, and one be positioned at second butted section 23 of the second spacing raceway groove 13, this first butted section 22 and second butted section 23 is connected in linkage section 21 two ends, and first butted section 22 is provided with inflexed first support 221; Accordingly, this first butted section 22 and second butted section 23 clips the 3 weeks side that arise from being mounted in fixing slot 11, make screwdriver head 3 be difficult for deviating from fixing slot 11, and when pulling away screwdriver head 3, these first butted section of 22 end can support in the first spacing hole 111, makes elastic clamp ring 2 be not easy to pull away and in process, departs from fixing slot 11 (aforementioned is the technical characteristics of the main embodiment of the present invention).
The further technical characterictic of the present invention, this first spacing raceway groove 12 and the second spacing raceway groove 13 are oppositely arranged, and the first spacing raceway groove 12 and the second spacing raceway groove 13 are offered toward bottom land direction from fixing slot 11 notches respectively.
The further technical characterictic of the present invention, this second butted section 23 is provided with second support 231 toward fixing slot 11 interior bendings, when screwdriver head 3 is fastened in fixing slot 11, this first support 221 and the second support 231 clip screwdriver head 3, to limit screwdriver head 3 arbitrarily in fixing slot 11 intrinsic displacements.
Refer to shown in Fig. 4 to Fig. 6, this elastic clamp ring 2 is mounted in fixing slot 11, and the linkage section 21 of elastic clamp ring 2 is butted on the bottom land of fixing slot 11, and first support 221 of first butted section 22 is arc bending shape to the interior bending of fixing slot 11, and first butted section of 22 end compared with the first spacing hole 111 away from fixing slot 11 notches, and second support 231 of second butted section 23 bends to arc bending shape in fixing slot 11, when installing accordingly screwdriver head 3 and entering fixing slot 11, all sides of this screwdriver head 3 can clip in first support 221 of first butted section 22 and second support 231 of second butted section 23, this first butted section 22 and second butted section 23 is positioned at relative position, therefore its to clip strength be relative, can be fastening clip screwdriver head 3, restriction screwdriver head 3 departs from arbitrarily fixing slot 11.
And when wish is changed screwdriver head 3, upwards screwdriver head 3 is pulled away to fixing slot 11, due to elastic clamp ring 2 fastening clip screwdriver head 3, therefore process Elastic clamp ring 2 can be upwards with displacement, as shown in Figure 6, the linkage section 21 of this elastic clamp ring 2 leaves fixing slot 11 bottom lands to top offset, because first butted section 22 and second butted section 23 of this elastic clamp ring 2 is limited in fixing slot 11 perisporiums, therefore elastic clamp ring 2 holds power state in elasticity, related when elastic clamp ring 2 is up taken away to fixing slot 11 through the first spacing hole 111 and the second spacing hole 112 when arising from 3, remove the spacing of fixing slot 11 for this first butted section 22 and second butted section 23, and support respectively into the first spacing hole 111 and the second spacing hole 112, limit according to this elastic clamp ring 2 and taken away fixing slot 11 simultaneously, promote user and operate to obtain convenience, more can promote operating efficiency.
Above-mentionedly only take that to be provided with the first spacing hole 111 be example, yet, can effectively limit by the quantity of spacing hole elastic clamp ring 2 and depart from fixing slot 11, in this second spacing raceway groove 13, offer one second spacing hole 112, this second butted section 23 can be supported into the second spacing hole, and groove 11 is not consolidated in easy glide card release, but it is identical with the enforcement kenel that is only provided with the first spacing hole 111, when sliding onto the second spacing hole for second butted section 23, its end can fasten into the second spacing hole and go out fixing slot 11 as limiting elastic clamp ring 2 displacements.
In addition, refer to shown in Fig. 7 to Fig. 9, these card circular groove 11 cell walls are provided with a limited ring groove 14, and this limited ring groove 14 is communicated with the first spacing raceway groove 12 and the second spacing raceway groove 13, and is crisscross arranged with the first spacing raceway groove 12 and the second spacing raceway groove 13.This first butted section 22 and second butted section 23 can, by slipping in limited ring groove 14, be gone out fixing slot 11 and limit elastic clamp ring 2 slippages accordingly.
Refer to shown in Fig. 1 and Fig. 7; this first support 221 and the second support 231 are arc bending shape or the convex tip shaped toward fixing slot 11 interior bendings; the present embodiment is not limited the first support 221 and the second support 231 shapes, if the shape of the first support 221 and the second support 231 can effectively clip and fixedly screwdriver head 3 all in protection category of the present invention.
The above, it is only preferred embodiment of the present invention, not the present invention is done to any pro forma restriction, any simple modification, equivalent variations and modification that every foundation technical spirit of the present invention is done above embodiment, all still belong in the scope of technical solution of the present invention.
