The structure of vernier caliper is generally by the main scale that is provided with scale and be attached on the main scale slidable vernier two parts and form, be provided with movable inboard measuring jaw and outside measuring jaw between main scale and the vernier, interior measuring claw is commonly used to measure internal diameter, and the external pelivimetry pawl is commonly used to measure length and external diameter.The main scale of vernier caliper is unit with the millimeter generally, and 10,20 or 50 lattices are then arranged on the vernier, and according to the difference of lattice, vernier caliper can be divided into ten minutes degree vernier caliper, 20 fens degree vernier calipers, 50 fens degree lattice vernier calipers etc.Tail end at vernier scale is connected with a pit gauge, can be used for measuring flume or the tube the degree of depth.
Though the vernier caliper purposes is very wide, all need to use in a lot of occasions, but when measuring the thickness of irregularly shaped object, spill object or the body wall thickness measure of certain depth object is arranged for example is as cup wall thickness or bottom thickness, or the thickness of object in uneven thickness, as shell etc.Effectively measure owing to be difficult to the chucking location, therefore existing vernier caliper also can't satisfy the thickness measure requirement to this type objects.
Summary of the invention
Technical problem to be solved in the utility model is, overcome above-mentioned prior art vernier caliper and can not measure the problem of irregularity body thickness, and provide a kind of vernier caliper of measuring the irregularity body thickness, simple in structure, the easy to operate and accuracy of measurement height of this vernier caliper.
For solving the problems of the technologies described above, the technical solution of the utility model is achieved in that a kind of vernier caliper of measuring the irregularity body thickness, partly form by the main scale that is provided with scale and at the vernier two that main scale slides, be provided with inboard measuring jaw and outside measuring jaw between described main scale and the vernier, described outside measuring jaw is divided into the fixed amount claw that links to each other with main scale and the activity claw that links to each other with vernier, described fixed amount claw is equipped with the run through groove parallel with the main scale length direction with the centre of activity claw, described two run through on the groove to cooperate respectively and are installed on steel ruler, described two steel rulers are on same straight line, and two steel rulers stretch out and run through groove.
The corresponding end of described two steel rulers is trapezium structure.
Described two to run through being shaped as of the groove medial extremity corresponding with two steel rulers trapezoidal.
Described fixed amount claw compresses steel ruler by the trip bolt of installing thereon.
Described activity claw compresses steel ruler by the trip bolt of installing thereon.
The beneficial effects of the utility model, the utility model is by being installed in the steel ruler on the measuring jaw of the outside, irregularly shaped object to be measured is placed between two steel rulers, thereby make irregularly shaped object to be measured that the sufficient space of laying be arranged, come the two sides of clamping and positioning irregularly shaped object to be measured with two steel rulers, can carry out the measurement of irregularity body thickness, easy to use, and the accuracy of measurement height.
Because the trapezium structure on the steel ruler, the contact area when having guaranteed to measure can increase accuracy when measuring.
Above-mentioned explanation only is the general introduction of technical solutions of the utility model, for can clearer understanding technological means of the present utility model, and can be implemented according to the content of instructions, and for above-mentioned purpose of the present utility model, feature and advantage can be become apparent, below especially exemplified by preferred embodiment, illustrated.

Embodiment
Be to reach technological means and the effect that predetermined goal of the invention is taked for further setting forth the utility model, below in conjunction with accompanying drawing and preferred embodiment, to embodiment, structure, feature and the effect thereof according to the vernier caliper of the measurement irregularity body thickness that the utility model proposes, describe in detail as after.
As shown in Figure 1, a kind of vernier caliper of measuring the irregularity body thickness of the utility model is made up of main scale 1, vernier 2, inboard measuring jaw 3, outside measuring jaw 4 and pit gauge 5.
Described main scale 1 is provided with degree of reading scale, and vernier 2 can slide at main scale 1.Inboard measuring jaw 3 and outside measuring jaw 4 are located between main scale 1 and the vernier 2, and pit gauge 5 links to each other with vernier 2 tail ends.
Described outside measuring jaw 4 is divided into fixed amount claw 6 and activity claw 7, fixed amount claw 6 links to each other with main scale 1, activity claw 7 links to each other with vernier 2, described fixed amount claw 6 and the centre of activity claw 7 are equipped with parallel with the main scale 1 length direction groove 8 that runs through, described two run through on the groove 8 to cooperate respectively and are installed on steel ruler 9, described two steel rulers 9 and stretch out and run through groove 8 on same straight line.Steel ruler 9 can be selected narrow, thin type, is convenient for carrying and uses.
