传感器1安装于连接杆2的前端，以便于感应检测。
转轴零件3与连接杆2的另一端连接，下壳15的端部具有开槽及内部 具有半圆卡槽，转轴零件3安装于下壳15内部半圆卡槽中。转轴零件3的前端伸出开槽，且转轴零件3的前端具有进线口，连接杆2插入转轴3的进线口，连接杆2与转轴3固定连接。驱动连接杆2转动能够带动转轴零件3在下壳15半圆卡槽中转动。
增速发电动机包括增速齿轮组4和发电机本体5，增速发电机安装于下壳15。增速齿轮组4的输入轴与转轴零件3相对固定连接，可以传递转轴零件3转动机械力。转轴零件3转动即带动增速齿轮组4的输入轴转动，从而带动增速齿轮组4的齿轮组转动，增速齿轮组4的齿轮组逐级增速。
发电机本体5的输入端齿轮与增速齿轮组4的齿轮相啮合，通过齿轮组逐级增速放大后传递到发电机本体5的输入端齿轮上并使之高速转动，从而使发电机本体5发出电量，在经过整流电路整流后存储于电容器中，为产品提供了电源。

液晶片11用于显示传感器1的测量数值，液晶片11与电路板13电连接，液晶片11即显示传感器1的即时测量数值，测量仪处于开机状态，此时即可以进行测量工作。
应用本发明实施例所提供的技术方案，利用连接杆2和转轴零件3的转动机械力使发电机本体5发电，把连接杆2、转轴零件3与增速齿轮组4的输入轴同轴套在一起，使发电装置与测试仪自然、完美地融为一体，结构更加紧凑，使用上也更为方便；利用发电机本体5为温度计、盐度计等测量仪提供电能，不使用电池，不用更换电池，不再需要强光，只需要驱动驱动装置，便可拥有足够电量以驱动产品工作，随时随地都可用，使用者使用更放心，使用更方便，避免了使用过程中电池电量不足无法使用的 问题，不需要使用电池，较为环保。
在上述具体实施方式的基础上，下壳15的一端内部具有半圆卡槽，探针组件中的转轴零件3铰合连接安装于半圆卡槽处，转轴零件3为T字型，转轴零件3与下壳15内半圆卡槽相配合。转轴零件3能够以半圆卡槽为轴承转动，探针组件能以半圆卡槽的轴线为转动轴线开合转动，并带动增速发电机发电，结构简单，结构更加紧凑，使用上也更为方便。
优选地，半圆卡槽的轴线与增速齿轮组4的输入轴的轴线重合。
进一步优化上述技术方案，增速齿轮组4的输入轴为D型轴，转轴零件3的侧边具有与D型轴相配合的D型孔，D型孔与D型轴相套合连接，结构简单，易于连接。
在上述任意一个实施例的基础之上，转轴零件3为包括有第一端口、第二端口和第三端口的T型轴，转轴零件3的进线口和出线口分别设置于第一端口和第二端口上，第一端口和第二端口的轴线相互垂直，D型孔开设于转轴3的第三端口处，第二端口和第三端口的轴线相互重合，转轴零件3结构较为常见，易于加工；进线口和出线口开设较为方便，易于加工贯穿；易于D型孔与D型轴连接。
在上述任意一个实施例的基础之上，转轴零件3的进线口与连接杆2通过紧配合装配，连接方便，固定牢固。连接杆2为具有中心孔的管状体，转轴零件3上具有与进线口连通的出线口，传感器1的连接导线穿入连接杆的中心孔且从出线口引出，连接导线的引出端焊接于电路板13上，传感器1的导线内置于连接杆2和转轴零件3的孔中，导线不易损坏，较为可靠。
本发明所提供的自发电测量仪，在其它部件不改变的情况下，下壳15的外侧具有长条槽，探针组件朝向长条槽的一侧转动，探针组件能够转动收拢于长条槽内。
测量仪处于未使用状态时，探针组件收拢在下壳15的长条槽中，使用时，把连接杆2从下壳15的长条槽向外转动，可以打开约180°，相应地转轴零件3也转动了约180°，与此同时转轴零件3通过增速齿轮组4的 输入轴带动增速齿轮组4转动，最后传递到发电机本体5的输入端齿轮并使之高速转动，从而使发电机本体5发出电量，在经过整流电路整流后存储于储能元件中，为产品提供了电源。
当测量工作完成后，在将探针组件收回下壳15的长条槽过程中，转轴零件3同样带动增速齿轮组4的输入轴转动，转速经过增速齿轮组4放大后传到发电机本体5的输入端齿轮上，使发电机本体5转子高速旋转，发电机本体5发出电能经过电路板13整流电路整流后存储在储能元件14中，储能元件14中存储的电量可以作为下一次使用的电能，合理利用电能。
需要说明的是，如果一次测量时间过长，或放置时未将探针组件收回到下壳15的长条槽中，测量仪可能因为电能消耗完而关机，此时可以一手抓住探针组件一手握住壳体相对转动，又能使发电机本体5发电而驱动温度计、盐度计等测试仪进行测量工作。
进一步地，增速发电机通过压紧架6固定于下壳15中，增速发电机卡于压紧架6中，压紧架6通过螺丝固定于下壳15，增速发电机安装较为方便。
在上述任意一个实施例的基础之上，电路板13固定于上壳7且位于液晶片11的下面，液晶片11和电路板13之间通过斑马条12连接，液晶片11、斑马条12及电路板13通过螺丝固定于上壳7，可以减少导线数量，较为整齐；通过斑马条12将电路板13的电信号传输到液晶片11上，接触面积较大，不易接触不良，电路板13和液晶片11连接较为可靠。
在上述任意一个实施例的基础之上，显示口处安装有胶镜10，液晶片11固定于上壳7且位于胶镜10的下面，胶镜10、液晶片11通过螺丝固定于上壳7。胶镜10为透明镜，通过胶镜10可以读取液晶片11显示的测量值，胶镜10对液晶片11以及壳体内部元件具有保护作用。
在上述任意一个实施例的基础之上，上壳7上具有若干个安装孔，每个安装孔内分别安装有一个功能按键，功能按键用于操控电路信号。
具体地说，上壳7上具有第一安装孔和第二安装孔，第一安装孔和第二安装孔内分别安装有第一按键8和第二按键9，第一按键8和第二按键9皆用于操控电路信号。
比如说，第一按键8为锁定按键8，锁定按键8可与电路板13的相应触点接触。传感器1只有指在被测位置，液晶片11才显示所测位置的测量值，传感器1离开或者偏离被测位置，液晶显示的测量值就可能改变或者很快消失。通过锁定按键8可以锁定液晶片11显示的测量值，即使传感器1离开被测位置，测量值也显示在液晶片11上，读取液晶片11显示的测量值更为方便、准确。
第二按键9为单位转换按键9，单位转换按键9可与电路板13的相应触点接触。比如，检测温度值时，单位可以在℃/°F之间切换，可以根据使用者的需求调整测量值的单位，不用人为换算，使用更为便捷。
本说明书中各个实施例采用递进的方式描述，每个实施例重点说明的都是与其他实施例的不同之处，各个实施例之间相同相似部分互相参见即可。
