Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of micrometer support frames, in particular to a micrometer measurement fixing bracket. Background Art
[0002] The micrometer is a tool for measuring length more accurately than a vernier caliper. It can measure length accurately to 0.01mm and has a measuring range of several centimeters. A part of it is processed into a thread with a pitch of 0.5mm. When it rotates in the screw sleeve of the fixed sleeve B, it will move forward or backward. The movable sleeve C is connected to the screw rod, and its periphery is divided into 50 equal grids. The number of full turns of the screw rod is measured by the 0.5mm interval scale on the fixed sleeve, and the part less than one turn is measured by the scale around the movable sleeve. The final measurement result needs to be estimated to one decimal place. When using the micrometer, it needs to be clamped on the fixed frame for easy measurement. However, the current fixed frame can only fix and support the micrometer. When the micrometer clamps the part to be measured, it needs to be read. Due to gravity, if the staff does not hold the part to be measured with their hands during the reading process, it may fall. If the part to be measured is held, it is not convenient for the staff to read accurately.
[0003] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0023] Specifically, after fixing the micrometer, the support rod 102 is rotated vertically inside the storage groove 101, and the limit rod 202 is extended to the inside of the limit hole 108 under the elastic force of the spring 201, so that the support rod 102 is fixed in a vertical state, and the support plate 106 is moved upward by rotating the screw 103, and the rotating ball 105 is rotated inside the arc groove 104 to make the support plate 106 vertically support the bottom of the part to be measured clamped by the micrometer, so as to avoid the part to be measured from falling due to gravity if the staff does not hold the part to be measured with their hands during reading, resulting in inaccurate reading.
[0024] Furthermore, a first through slot 203 is provided at the top of the front end of the fixing frame base 1, the cavity 2 is connected to the first through slot 203, a lever 204 is slidably installed inside the first through slot 203, and the lever 204 is fixedly connected to the limit rod 202;
