Abstract
The utility model discloses a pair of screw clamping pliers. The screw clamping pliers comprise a first pliers body and a second pliers body, wherein the first pliers body and the second pliers body are hinged to each other in an intersecting mode. The first pliers body comprises a first pliers head and a first pliers handle, wherein the first pliers head and the first pliers handle are distributed on the two sides of the junction point respectively. The second pliers body comprises a second pliers head and a second pliers handle, wherein the second pliers head and the second pliers handle are distributed on the two sides of the junction point respectively. A first upper positioning seat and a first lower positioning seat are distributed on the inner side wall of the first pliers head in a front-and-back spaced mode. A second upper positioning seat corresponding to the first upper positioning seat and a second lower positioning seat corresponding to the first lower positioning seat are arranged on the inner side wall of the second pliers head. The first upper positioning seat, the first lower positioning seat, the second upper positioning seat and the second lower positioning seat are respectively provided with a round rotating pinch roller in a rotating mode. The screw clamping pliers have the advantages that a screw can be clamped stably and reliably, clamping accuracy is good, the screw does not fall off easily, screw-in resistance to the screw is low, and deformation damage to a screw head caused by clamping can be effectively avoided.
Description
Technical field
The utility model relates to a kind of hardware & tools, specifically refers to a kind of screw gripper clamp that screw is installed of being convenient to.
Background technology
Screw is a kind of conventional Hardware fitting, is widely used in and builds in work, machinery or clinical medicine operation.Present screw when mounted, generally all uses finger to clamp screw, then with screwdriver rotation, is screwed into, and this mode screw easily skids and drops, and easily stabs finger when screwdriver is screwed into.
In addition, existing screw is installed also to have and need to be adopted the instruments such as clamp by screw clamping position, then utilize screwdriver rotation to be screwed into, this mode shortcoming be: (1), clamping stability are poor, often there is screw landing, and this method of clamping easily makes the screw of clamping occur, cause screw to be screwed into difficulty;
(2), during clamp pinching screw, make the rotation of screw be screwed into resistance large, and clamp clamp and also easily cause head of screw deformed damaged.
Summary of the invention
The purpose of this utility model is the shortcoming and defect existing in order to overcome prior art, and provides a kind of screw that is applicable to install, and clamps reliable and stablely, and clamping accuracy is good, is difficult for landing, and rotation is screwed into the screw gripper clamp that resistance is little to screw.
For achieving the above object, the technical solution of the utility model is the first caliper and the second caliper that includes mutual cross-articulation, the first described caliper includes the first binding clip and the first clamp handle that is distributed in its interface point both sides, the second described caliper includes the second binding clip and the second clamp handle that is distributed in its interface point both sides, before and after on the madial wall of the first described binding clip, be intervally distributed with positioning seat and first time positioning seat on first, on the madial wall of the second described binding clip, be provided with positioning seat and second time positioning seat on corresponding with positioning seat on first and first time positioning seat second, positioning seat on described first, first time positioning seat, on second, on positioning seat and second time positioning seat, all rotate and be provided with circular rotation pinch roller.
By this setting, adopt four rotation pinch rollers to clamp screw, ensured the stability of screw clamping, and screw is when rotation is screwed into, four rotation pinch rollers can be around rotating shaft rotation separately, therefore, can not cause larger resistance to the rotation of screw, effectively prevent from rotating the deformed damaged of pinch roller to head of screw simultaneously yet.
Further arrange in the both sides up and down of the wheel rim that is described rotation pinch roller and be provided with scalene cone at least on one side.The head of existing screw generally is inverted cone-shaped structure, by this setting, the head of screw dropping place of the back taper of screw, in scalene cone, can further be improved to the stability of screw clamping, but also can reduce the resistance of screw turns.
Further arranging is the support plate that on described first, positioning seat includes two intervals that are longitudinally parallel to each other, these two support plates are laterally fixed on the madial wall of the first binding clip, described rotation pinch roller rotates and is arranged between two support plates, and the inner wheel rim of this rotation pinch roller is positioned at outside support plate.By this setting, convenient rotation of rotating pinch roller is installed.
In sum, the utility model has the advantages that screw clamp holds reliable and stablely, clamping accuracy is good, is difficult for landing, and it is little that screw rotation is screwed into resistance, and can effectively avoid the deformed damaged of clamping to head of screw.
Below in conjunction with specification drawings and specific embodiments, the utility model is described further.
Accompanying drawing explanation
Fig. 1 the utility model specific embodiment structural representation;
Fig. 2 the utility model specific embodiment stereogram;
Fig. 3 the utility model partial structurtes exploded view.
The specific embodiment
Below by embodiment, the utility model is specifically described; only for the utility model is further described; can not be interpreted as the restriction to the utility model protection domain, the technician in this field can hold utility model of the present invention some nonessential improvement and adjustment according to foregoing invention utility model.
The specific embodiment of the present utility model as Figure 1-3, include the first caliper 1 and second caliper 2 of mutual cross-articulation, the first described caliper 1 includes the first binding clip 11 and the first clamp handle 12 that is distributed in its interface point both sides, the second described caliper 2 includes the second binding clip 21 and the second clamp handle 22 that is distributed in its interface point both sides, before and after on the madial wall of the first described binding clip 11, be intervally distributed with positioning seat 111 and first time positioning seat 112 on first, on the madial wall of the second described binding clip 21, be provided with respectively positioning seat 211 and second time positioning seat 212 on corresponding with positioning seat on first 111 and first time positioning seat 112 second, positioning seat 111 on described first, first time positioning seat 112, on second, on positioning seat 211 and second time positioning seat 212, all rotate and be provided with circular rotation pinch roller 3, the both sides up and down of the wheel rim of the rotation pinch roller 3 described in the present embodiment are provided with scalene cone 31.Rotation pinch roller described in the present embodiment preferably adopts plastics or quality of rubber materials to make, and can certainly on the basis as matrix, put in metal wheel corresponding rubber sleeve and form.
In addition, on described in the present embodiment first, positioning seat 111 includes the support plate 1111 at two intervals that are longitudinally parallel to each other, these two support plates are laterally fixed on the madial wall of the first binding clip 11, described rotation pinch roller rotates and is arranged between two support plates, and the inner wheel rim of this rotation pinch roller is positioned at outside support plate.On first time positioning seat of the present embodiment 112, second, positioning seat 211 and second time positioning seat 212 are done corresponding setting with reference to positioning seat 111 on first.
