The provision of the round rod and the round hole has the effect of limiting the support frame inside the horizontal groove.
[0010] Preferably, a rectangular plate is fixedly mounted on the end surface of the vertical strip plate away from the strip groove, and a spring is fixedly mounted between the rectangular plate and the sliding plate. The setting of the spring has the effect of limiting the position of the sliding plate inside the groove.
[0011] Compared with the prior art, the advantages and positive effects of the utility model are:
[0012] 1. In the utility model, by setting the adjustment device, when the device needs to be used, firstly, the vehicle speed sensor is inserted into the interior of the mounting ring, and the test end of the vehicle speed sensor is kept facing the speed wheel, and then the first motor is started, and the first motor is started to drive the speed wheel to rotate. When the speed wheel rotates to the specified speed, the vehicle speed sensor is tested. When the distance between the vehicle speed sensor and the speed wheel needs to be changed, firstly, the scale plate is placed on the base from the outside, and then the second motor is started, and the second motor is started to drive the gear to rotate, and the gear rotates and meshes with the rack, so that the vertical plate moves inside the long groove, and the vertical plate moves inside the long groove to drive the connecting rod to move, and the connecting rod moves to drive the vertical bar plate to move inside the strip groove, and the vertical bar plate moves inside the strip groove to drive the mounting ring to move, and the mounting ring moves to drive the vehicle speed sensor to move. When the vehicle speed sensor is moving, the scale of the scale line can be compared. When the vehicle speed sensor moves to a suitable position, the second motor can be turned off. Through the cooperation of the above structure, the distance between the vehicle speed sensor and the speed wheel can be adjusted, so that different types of vehicle speed sensors can be tested, and the adaptability of the device is further improved.
[0013] 2. In the utility model, by setting a fixing device, when it is necessary to replace the corresponding mounting ring according to different types of vehicle speed sensors, first slide the sliding plate to make the sliding plate move inside the groove. The movement of the sliding plate inside the groove will squeeze the spring, so that the spring is compressed. At the same time, the movement of the sliding plate inside the groove also drives the round rod to move. The movement of the round rod causes it to move out of the inside of the round hole. The separation of the round rod and the round hole causes the support frame to lose its limit in the inside of the horizontal groove. At this time, the support frame can be moved and moved out of the inside of the horizontal groove to complete the disassembly operation between the mounting ring and the vertical strip. Through the cooperation of the above structure, the purpose of disassembling the mounting ring is achieved, thereby avoiding the need to replace the mounting ring, so that the mounting ring can be used to fix vehicle speed sensors of different types, further improving the versatility of the device.

[0033] Working principle: By setting the adjustment device 5, when it is needed to use the device, first insert the vehicle speed sensor into the inside of the mounting ring 505, keep the test end of the vehicle speed sensor facing the speed wheel 4, then start the first motor 3, the first motor 3 starts to drive the speed wheel 4 to rotate, when the speed wheel 4 rotates to the specified speed, the vehicle speed sensor is tested, when it is necessary to change the distance between the vehicle speed sensor and the speed wheel 4, first place the scale plate on the base 1 from the outside, and then start the second motor 509, the second motor 509 starts to drive the gear 510 to rotate, the gear 510 rotates and meshes with the rack 511, so that the vertical plate 507 is inside the long slot 506 The vertical plate 507 moves inside the long groove 506, driving the connecting rod 508 to move. The connecting rod 508 moves and drives the vertical bar plate 502 to move inside the strip groove 501. The vertical bar plate 502 moves inside the strip groove 501 and drives the mounting ring 505 to move. The mounting ring 505 moves and drives the vehicle speed sensor to move. When the vehicle speed sensor is moving, the scale of the scale line can be compared. When the vehicle speed sensor moves to a suitable position, the second motor 509 can be turned off. Through the cooperation of the above structure, the distance between the vehicle speed sensor and the speed wheel 4 can be adjusted, so that different types of vehicle speed sensors can be tested, further improving the adaptability of the device.
