Figure 1 and Figure 2 As shown, when in use, first fit the support column 1 to the corresponding position on the external device to be tested, then plug and connect the movable plate 2 and the support rod 5, and at the same time form a sliding structure between the left side of the movable plate 2 and the support block 3. By moving the movable plate 2, the movable plate 2 and the support rod 5 and the movable plate 2 and the support block 3 slide, and the movable plate 2 drives the fixed clamping plate 4 to be clamped on the external device to be tested. Then, the fixing cap 6 threadedly connected to the outer surface of the support rod 5 is rotated so that the fixing cap 6 is fit to the right end of the movable plate 2, thereby facilitating the limiting of the position between the movable plate 2 and the support rod 5. Through the above operation, the support column 1 can be fixed to the device to be tested very conveniently without the need for bolts.

[0033] Embodiment 2: During the use of the existing sensor, it is not convenient to adjust the position of the speed sensor 12 and the speed gear 13 according to the actual use requirements, and it is relatively cumbersome to adjust the distance between the sensor and the object to be measured. Therefore, by setting a connecting mechanism 7, a speed sensor 12, a speed gear 13, a fixing plate 15, a spring 16, a fixing pin 17 and a pull rod 18, the connecting mechanism 7 includes a movable sleeve 8 sleeved on the outer surface of the support column 1, a movable rod 9 fixedly connected to the middle of the movable sleeve 8, a movable bracket 10 fixedly connected to the left end of the movable sleeve 8 and a mounting block 11 fixedly connected to the left end of the movable bracket 10, between the movable sleeve 8 and the support column 1 It constitutes a left-right sliding structure, the movable rod 9 is inserted in the middle of the support column 1, and the movable sleeve 8 drives the mounting block 11 to move left and right on the left side of the support column 1 through the movable bracket 10. A speed sensor 12 is fixedly installed in the middle of the mounting block 11, and a speed gear 13 is rotatably installed on the left side of the mounting block 11.

Figure 4 、 Figure 5 and Figure 6 As shown, by pulling the pull rod 18, the pull rod 18 slides with the fixed plate 15, and the pull rod 18 drives the fixed pin 17 to move, so that the fixed pin 17 squeezes the spring 16, and the spring 16 is elastically deformed, and the fixed pin 17 is pulled out from the fixed groove 19, thereby releasing the limit between the movable sleeve 8 and the support column 1, and then by pulling the movable sleeve 8, the movable sleeve 8 slides with the support column 1, and the movable sleeve 8 drives the movable rod 9 to slide with the support column 1, and the movable sleeve 8 drives the mounting block 11 to move between the support column 1 through the movable bracket 10. The left side moves left and right, thereby causing the mounting block 11 to drive the speed sensor 12 and the speed gear 13 to perform telescopic adjustment, thereby adjusting the distance between the speed sensor 12, the speed gear 13 and the object to be measured, so that the speed gear 13 is engaged with the gear on the object to be measured, thereby achieving a better detection effect. After the adjustment is completed, the pull rod 18 is directly released.
