Detailed description of the invention
The present invention reaches above-mentioned object and effect, and the technological means adopted 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 adapter 1 and an elastic clamp ring 2, wherein: this adapter 1 is provided with a fixing slot 11, this fixing slot 11 inwall cuts open establishes the first spacing raceway groove 12 and the second spacing raceway groove 13 (the spacing raceway groove of the present embodiment first 12 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 takes the shape of the letter U shape, and elastic clamp ring 2 comprises first butted section 22 that a linkage section 21 and is positioned at the first spacing raceway groove 12, and one is 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 to 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 to be mounted on and arises from 3 weeks sides in fixing slot 11, screwdriver head 3 is made not easily to deviate from fixing slot 11, and in time 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 in process and depart from fixing slot 11 (the aforementioned technical characteristics for the main embodiment of the present invention).
The further technical characteristic 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 from fixing slot 11 notch toward bottom land direction respectively.
The further technical characteristic of the present invention, this second butted section 23 is provided with second support 231 bending in fixing slot 11, 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 displacement.
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 bending in arc bending shape in fixing slot 11, and first butted section of 22 end comparatively the first spacing hole 111 away from fixing slot 11 notch, and second support 231 of second butted section 23 bends to arc bending shape in fixing slot 11, when installing screwdriver head 3 enters fixing slot 11 accordingly, all sides of this screwdriver head 3 can clip the second support 231 of the first support 221 in first butted section 22 and second butted section 23, this first butted section 22 and second butted section 23 is positioned at relative position, therefore it clips strength is relative, what energy was fastening clips screwdriver head 3, restriction screwdriver head 3 departs from fixing slot 11 arbitrarily.
And when for changing screwdriver head 3, upwards screwdriver head 3 is pulled away fixing slot 11, due to elastic clamp ring 2 fastening clip screwdriver head 3, therefore process Elastic clamp ring 2 upwards can be with displacement, as shown in Figure 6, the linkage section 21 of this elastic clamp ring 2 leaves fixing slot 11 bottom land 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 perisporium, therefore elastic clamp ring 2 is in elasticity and stores power state, when arise from 3 related elastic clamp ring 2 is up taken away fixing slot 11 through the first spacing hole 111 and the second spacing hole 112 time, namely the spacing of fixing slot 11 is removed for this first butted section 22 and second butted section 23, and support into the first spacing hole 111 and the second spacing hole 112 respectively, limit elastic clamp ring 2 according to this and taken away fixing slot 11 simultaneously, promote user and operate to obtain convenience, more operating efficiency can be promoted.
Above-mentioned only to be provided with the first spacing hole 111, but, can effectively limit elastic clamp ring 2 by the quantity of spacing hole and depart from fixing slot 11, one second spacing hole 112 is offered in this second spacing raceway groove 13, 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 being only provided with the first spacing hole 111, when sliding onto the second spacing hole for second butted section 23, its end can fasten and go out fixing slot 11 into the second spacing hole as the displacement of restriction elastic clamp ring 2.
In addition, refer to shown in Fig. 7 to Fig. 9, this card circular groove 11 cell wall is 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 accordingly, and limited elastic clamp ring 2 slippage and go out fixing slot 11.
Refer to shown in Fig. 1 and Fig. 7; this first support 221 and the second support 231 are in the arc bending shape bent in fixing slot 11 or convex tip shaped; the present embodiment is not limited the first support 221 and the second support 231 shape, as long as the shape of the first support 221 and the second support 231 effectively can clip and fix screwdriver head 3 all in protection category of the present invention.
The above, it is only preferred embodiment of the present invention, not any pro forma restriction is done to the present invention, every above embodiment is done according to technical spirit of the present invention any simple modification, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
