Description
Technical field
The present invention relates to the technical field of orthopedic instrument production, specifically a kind of acetabular outer cup groove and joint handle body bottom
Calipers.
Background technique
Vernier caliper is generally used to the detection measurement of product in production process, common vernier caliper includes blade, trip
Scale, main scale, the first measuring claw and the second measuring claw, wherein main scale is mutually fixed with blade, shows scale on main scale, vernier scale with
Blade matches to merge to be slided along blade, and the first measuring claw includes the first main measuring claw being arranged in pairs and first from measuring claw, the
Two measuring claws include that the second main measuring claw being arranged in pairs and second are divided from measuring claw, the first main measuring claw and the second main measuring claw
It is not fixedly installed on the two sides of blade, first is fixedly installed on the two sides of vernier scale from measuring claw and second from measuring claw respectively,
The internal diameter of product is measured by the first measurement end that the first measuring claw is formed under normal circumstances, and formed by the second measuring claw
The outer diameter of second measurement end measurement product.But since the structure of acetabular outer cup and joint handle is more special, acetabular outer cup it is recessed
All there is interference term in slot and joint handle body bottom diameter, can not obtain accurate measurement using conventional vernier caliper in measurement process
Value.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of acetabular outer cup groove and joint handle body bottom calipers.
The technical scheme adopted by the present invention to solve the technical problems existing in the known art is that
Acetabular outer cup groove and joint handle body bottom calipers of the invention, including blade, vernier scale, main scale, the first measurement
Pawl and the second measuring claw, wherein main scale is mutually fixed with blade, shows that scale, vernier scale merge with blade matching along blade on main scale
Sliding, the first measuring claw include the first main measuring claw being arranged in pairs and first from measuring claw, and the second measuring claw includes setting in pairs
The main measuring claw of second set and second is fixedly installed on blade from measuring claw, the first main measuring claw and the second main measuring claw respectively
Two sides, first is fixedly installed on the two sides of vernier scale from measuring claw and second from measuring claw respectively, what the first measuring claw was away from each other
Two outer rims are the first measurement end, and the first main measuring claw with and first be respectively set recess from the outer end of measuring claw notch, from
And the external pelivimetry head of the first measurement end is formed from measuring claw in the first main measuring claw and first；Second measuring claw it is opposite two in
Edge is the second measurement end, and the second main measuring claw and second be respectively set recess from the inner end of measuring claw notch, thus the
Two main measuring claws and second form the second measurement end from measuring claw interior measuring head.
The present invention can also use following technical measures:
Setting measurement numeric display unit on the vernier scale.
The advantages and positive effects of the present invention are:
In acetabular outer cup groove and joint handle body bottom calipers of the invention, on the first measuring claw and the second measuring claw respectively
The notch of recess is set, and the interior measuring head of the external pelivimetry head and the second measurement end that make the first measurement end avoids measurement interference respectively
Position improves production efficiency so as to accurately obtain the measurement data of corresponding position.In addition, the present invention can be simultaneously
Applied to the different position datas of two kinds of instruments of measurement, refer to wider applicability.
