A connecting mechanism 8 is provided on the connecting frame 3, and an adjustment mechanism 9 is provided on the handle 5.

[0022] Please see Figure 1 , Figure 2 , Figure 3The connecting mechanism 8 includes a pull rod 81, which is slidably sleeved inside the connecting frame 3. A first spring 82 is provided on the outer side of the pull rod 81. One end of the first spring 82 is fixedly connected to the pull block 83, and the other end of the first spring 82 is fixedly connected to the connecting frame 3. By designing the first spring 82, the force of the first spring 82 can act on the pull block 83. The pull block 83 is fixedly connected to the outer side of the pull rod 81 and is slidably connected to the connecting frame 3. The end of the pull block 83 away from the pull rod 81 is fixedly connected to... There is a connecting rod 84, and a magnetic plug 85 is fixedly connected to the outside of the connecting rod 84. Both the connecting rod 84 and the magnetic plug 85 are slidably connected to the connecting frame 3. The magnetic plug 85 is slidably connected to the measuring instrument body 1. The measuring instrument body 1 has a slot 86 inside, and the magnetic plug 85 is slidably connected inside the slot 86. By designing the slot 86, the magnetic plug 85 can slide inside the slot 86. A magnet 87 is fixedly connected inside the connecting frame 3. By designing the connecting mechanism 8, it is convenient to disassemble the connecting frame 3.

[0023] Please see Figure 1 , Figure 4 The adjusting mechanism 9 includes a groove 91. A groove 91 is formed inside the connecting post 4. A ball bearing 92 is movably fitted inside the groove 91. There are multiple grooves 91, evenly distributed inside the connecting post 4. By designing multiple grooves 91, the ball bearing 92 can roll into different positions within the grooves 91. A connecting rod 93 is movably fitted outside the ball bearing 92. The connecting rod 93 is slidably connected to the connecting post 4 and fixedly connected to the handle 5. A slider 94 is movably fitted outside the ball bearing 92. The slider 94 is connected to the connecting rod 92. 3. Sliding connection: A hinge rod 95 is hinged to the outer side of the slider 94, and a sliding sleeve 96 is hinged to the other end of the hinge rod 95. A guide rod 97 is slidably sleeved inside the sliding sleeve 96. The guide rod 97 is fixedly connected to the connecting rod 93. A second spring 98 is provided on the outer side of the guide rod 97.

Through the function of handle 5, anti-slip sleeve 6 and anti-slip protrusion 7, the measuring instrument body 1 can be easily held and used, making it more portable. When the length of handle 5 needs to be adjusted, simply pull handle 5. Handle 5 will cause connecting rod 93 to slide along connecting post 4. Connecting rod 93 will cause ball bearing 92 to roll along the arc surface of groove 91. Ball bearing 92 will be squeezed and will cause slider 94 to slide into connecting rod 93. Hinged rod 95 will deflect and push sliding sleeve 96 to slide along guide rod 97. Sliding sleeve 96 will squeeze second spring 98, which can separate ball bearing 92 from groove 91. As handle 5 moves, the elasticity of second spring 98 will give sliding sleeve 96 a counter-force, which can push ball bearing 92 back into the groove 91 in another position. When handle 5 is pulled, relative sliding between handle 5 and connecting post 4 can be achieved, which facilitates the extension of the length of handle 5 and further improves its use effect.

[0025] When it is necessary to disassemble the connecting frame 3, simply pull the pull rod 81 outward. The pull rod 81 drives the pull block 83 to move. The pull block 83 compresses the first spring 82. At the same time, the pull block 83 drives the connecting rod 84 and the magnetic plug 85 to move horizontally. When the magnetic plug 85 is attracted to the magnet 87, the magnetic plug 85 can be pulled out from the measuring instrument body 1. Then the connecting frame 3 can be removed from the measuring instrument body 1, making it more flexible to use.
