[0038] like Figure 1-13 As shown, a handheld tool for monitoring a switch gap comprises a base 3, a ruler 7, a pressure plate 8, and a handle 12. A slot 14 for receiving the ruler 7 is defined at the top of the base 3. The slot 14 extends from front to back, and the ruler 7 is inserted into the slot 14. The pressure plate 8 is secured to one edge of the slot 14 by bolts 9, pressing the ruler 7. The rear end of the base 3 is connected to the handle 12. A protruding rod 2 is provided at the front end of the base 3, with a latch 1 at the front end that engages the edge of the gap. The protruding rod 2 is narrower than the width of the base and is located near the center of the front end of the base 3. The rod 2 extends long enough to avoid the side walls of the contact seat and reach the inspection post.

[0039] The front end of the ruler 7 is fixed with a protruding column 6, which is narrower than the width of the ruler 7 and is located in the middle of the front end of the ruler 7. Its left and right sides are aligned with the extension rod 2 up and down, and the protruding column 6 can avoid the side wall of the contact seat and extend to the inspection column position.

[0040] Scales are provided on the corresponding positions of the ruler 7 and the pressure plate 8. A zero adjustment column 10 is fixed to the lower end of the ruler 7. The lower end of the ruler 7 is connected to the base 3 through a spring 13. When in the zero adjustment state, the zero points of the scales of the ruler 7 and the pressure plate 8 are aligned. At this time, the zero adjustment column 10 is stuck at the front end of the base 3. A first knob 4 is provided on one side of the base 3. After the ruler 7 is measured, the first knob 4 passes through one side of the base 3 and locks the ruler 7.

[0041] A rectangular hole 21 is formed at the tail end of the card slot 14, a spring mounting plate 16 connected to the base 3 is fixed in the rectangular hole 21, a spring hook column 17 is fixed in the spring mounting plate 16, a spring hole 15 is formed at the tail end of the ruler 7, a screw is fixed in the spring hole 15, and the spring 13 is connected between the spring hook column 17 and the screw.

[0042] The rear end of the base 3 is provided with a slot 5 for receiving a handle 12, which is locked in place using a second knob 11. Two slots 5 are provided, one on each side of the rear end of the base 3. Depending on the location of the gap to be measured, the handle 12 can be attached to either side for measurement. Once the gap is measured, the second knob 11 is used to secure the ruler 7, completing the reading.

[0043] A limiting plate 20 is fixedly provided on the base 3 above one side of the slot 14, and a limiting groove 19 is formed between the limiting plate 20 and the bottom end of the slot 14. One side of the ruler 7 is inserted into the limiting groove 19, and the other side of the ruler 7 is pressed against the ruler 7 by the pressing plate 8.
