Description
Technical field
The present invention relates to measuring tool, in particular to a kind of vernier caliper.
Background technique
Vernier caliper is a kind of measurer for measuring length, internal-and external diameter, depth.Vernier caliper is by main scale and is attached to energy on main scale
Vernier two parts of sliding are constituted.The maximum measurement length of existing vernier caliper is usually all the range on fixed main scale, Gu
Determine main scale length be it is certain, can survey that range is small, and use is limited；If increased by the length for continuing the fixed main scale of extension
It, will be not readily portable if the range of fixed main scale.
Summary of the invention
Technical problem to be solved by the present invention lies in for the above-mentioned prior art can survey range it is small, it is not readily portable etc. no
Foot, providing a kind of can not only survey that range is big but also portable vernier caliper.
In order to solve the above technical problems, the present invention adopts the following technical scheme:
A kind of vernier caliper, including fixed main scale, detachable main scale, movable main scale, the first claw, with the first claw phase
The second claw matched.Second claw is fixed on movable main scale.Movable main scale is slidably arranged on fixed main scale.On fixed main scale
Equipped with the first mounting hole.First claw is equipped with the second mounting hole.The both ends of detachable main scale are equipped with third mounting hole and the 4th
Mounting hole.Detachable main scale is equipped with grooving close to that side of the 4th mounting hole.The length of detachable main scale is less than on fixed main scale
Range.
When the measurement length of undetected object body is less than or equal to the range on fixed main scale, the first claw passes through the first installation
Hole, the second mounting hole and fastener are detachably arranged on fixed main scale.
When the measurement length of undetected object body is greater than the range on fixed main scale and is less than or equal to the range fixed on main scale
When with the sum of range on detachable main scale, detachable main scale can by grooving, the first mounting hole, the 4th mounting hole and fastener
Disassembly setting is on fixed main scale.First claw is detachably arranged at by the first mounting hole, third mounting hole and fastener can
It dismantles on main scale.
The fastener is screw bolt and nut in one of the embodiments,.
The movable main scale is equipped with vernier fastening screw in one of the embodiments, convenient for reading.
The detachable main scale is equipped with label in one of the embodiments,.
Advantages of the present invention and the utility model has the advantages that
It is big that the present invention can survey range, while range can be surveyed by increasing, between the fixed main scale of the present invention and detachable main scale
Detachably, easy to carry.The present invention is equipped with vernier fastening screw convenient for reading.The present invention is accurate while range can be surveyed by increasing
It spends also high.

Above or there may also be elements placed in the middle.When an element be considered as with another element " being connected ", it can be directly
It is connected to another element, or may be simultaneously present centering elements.
Unless otherwise defined, all technical and scientific terms used herein and belong to technical field of the invention
The normally understood meaning of technical staff is identical.Term as used herein in the specification of the present invention is intended merely to description tool
The purpose of body embodiment, it is not intended that in the limitation present invention.
Embodiment 1
Please refer to Fig. 1 to Fig. 6, a kind of vernier caliper, including fixed main scale 1, detachable main scale 3, movable main scale 5, first
Claw 7, the second claw 9 to match with the first claw 7.
Wherein, the second claw 9 is fixed on movable main scale 5.Movable main scale 5 is slidably arranged on fixed main scale 1.
Specifically, fixed main scale 1 is equipped with the first mounting hole 11.First claw 7 is equipped with the second mounting hole 71.Detachably
The both ends of main scale 3 are equipped with third mounting hole 91 and the 4th mounting hole 93.Detachable main scale 3 is set close to that side of the 4th mounting hole 93
There is grooving 95.The length of detachable main scale 3 is less than the range on fixed main scale 1.
As shown in figures 1 to 6, when the measurement length of undetected object body is less than or equal to the range on fixed main scale 1, first
Claw 7 is detachably arranged on fixed main scale 1 by the first mounting hole 11, the second mounting hole 71 and fastener.
