[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. However, the embodiments described below are only some embodiments of the present utility model, and not all of them. If other embodiments are obtained by those skilled in the art without creative effort, they shall fall within the protection scope of the present utility model.

[0024] Reference Figures 1 to 4 The on-site testing and positioning tool for engineering testing includes a base 1, a stop rod 2, a connecting mechanism 3, a rotating rod 4, a scale 5, a locking mechanism 6, a threaded rod 7, and a pointer 8. The stop rod 2 is connected to the base 1. The stop rod 2 controls the device to abut against the wall, thereby connecting the connecting mechanism 3 to the stop rod 2, the rotating rod 4 to the connecting mechanism 3, the scale 5 to the rotating rod 4, the locking mechanism 6 to the base 1, the threaded rod 7 to the locking mechanism 6, and the pointer 8 to the threaded rod 7. When the stop rod 2 abuts against the wall, the connecting mechanism 3 controls the rotating rod 4 to rotate so that the scale 5 is exposed. When the rotating rod 4 rotates, the locking mechanism 6 controls the threaded rod 7 to unlock and controls the pointer 8 to move.

[0025] As one embodiment of this utility model, refer to Figures 2 to 4The connecting mechanism 3 includes a limiting block 31, a limiting rod 32, a buffer spring 33, a rack 34, a main gear 35, a secondary gear 36, and a fitting unit 37. The limiting block 31 is connected to the abutment rod 2, the limiting rod 32 cooperates with the limiting block 31, and the buffer spring 33 is connected to the limiting block 31. The buffer spring 33 can buffer the movement of the abutment rod 2 in the motion groove 38, and can also control the abutment rod 2 to return to its original position after use due to its elasticity. The rack 34 is connected to the abutment rod 2, the main gear 35 cooperates with the rack 34, and the main gear 35 cooperates with the secondary gear 36. The fitting unit 37 is connected to the limiting block 31. The base 1 has a motion groove 38 and a limiting groove 39 respectively, which are connected. There are two limiting grooves 39 symmetrically arranged around the center line of the motion groove 38. The abutment rod 2 cooperates with the motion groove 38, and the limiting block 31... In conjunction with the limiting groove 39, the above-mentioned settings can limit the movement of the stop rod 2 and the limiting block 31, and prevent the movement of the stop rod 2 and the limiting block 31 from deviating. The gear ratio of the main gear 35 and the secondary gear 36 is 1:5-1:10, and the axes of the main gear 35 and the secondary gear 36 are located on the same horizontal line. Through the above-mentioned settings, the main gear 35 can rotate at a faster speed than the secondary gear 36, so that when the limiting block 31 moves to the end of the limiting groove 39, the scale 5 can be rotated to face upwards, thus enabling the observation of length. The length of the movement groove 38 is two-thirds of the length of the pointer 8, and the height of the pointer 8 above the base 1 is less than the length of the movement groove 38. Through the above-mentioned settings, it can be ensured that the pointer 8 is always located below the connecting plate 371, which can prevent the pointer 8 from directly contacting the wall, thus protecting the pointer 8.

[0026] As one embodiment of this utility model, refer to Figure 3 and Figure 4 The fitting unit 37 includes a connecting plate 371 and a telescopic spring 372. The connecting plate 371 is connected to the limiting block 31, and the telescopic spring 372 is connected to the connecting plate 371. With the above arrangement, the device can fit against the wall when it comes into contact with the wall, which facilitates the observation of dimensions. The connecting plate 371 has a through groove 373 that cooperates with the pointer 8. The base 1 has a rectangular groove 9 that cooperates with the pointer 8. The length of the rectangular groove 9 is the same as the length of the through groove 373. With the above arrangement, the movement distance of the pointer 8 can be limited, and the pointer 8 can be moved conveniently.

[0027] As one embodiment of this utility model, refer to Figure 3 and Figure 4The locking mechanism 6 includes a drive gear 61 and a receiving gear 62. The drive gear 61 is connected to the rotating rod 4, and the receiving gear 62 engages with the drive gear 61. The drive gear 61 includes a flat part 611 and a toothed part 612. The curvature ratio of the flat part 611 to the toothed part 612 is 1:3. With the above settings, the engagement time of the drive gear 61 and the receiving gear 62 can be set. When the flat part 611 and the receiving gear 62 are in correspondence, the threaded rod 7 is unlocked. When the toothed part 612 and the receiving gear 62 are in correspondence and engaged, the threaded rod 7 can be locked, thereby enabling the rotation of the threaded rod 7.

[0028] Working principle: When in use, the user places the base 1 on the ground and then controls the base 1 to move towards the wall. As the base 1 gradually approaches the wall, the connecting plate 371 abuts against the wall. When the connecting plate 371 presses against the wall, it can drive the abutment rod 2 to move in the movement groove 38, and at the same time drive the limit block 31 to move in the limit groove 39. When the connecting plate 371 moves, it can compress the buffer spring 33, thereby achieving a buffering effect. When the abutment rod 2 is pushed, it can drive the main gear 35 to rotate through the rack 34. When the main gear 35 rotates, it can drive the secondary gear 36 to rotate. When the secondary gear 36 rotates, it can drive the scale 5 to rotate through the rotating rod 4, thereby exposing the scale 5. When the rotating rod 4 rotates, it can drive the receiving gear 62 to rotate through the teeth 612 of the drive gear 61. When the flat part 611 corresponds to the receiving gear 62, it can control the threaded rod 7 to rotate. When the threaded rod 7 rotates, it can drive the pointer 8 to move, thereby allowing the distance to be adjusted.
