[0030] Next, the technical solutions of the present utility model will be clearly and completely described in conjunction with the drawings in the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present utility model.
[0031] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "middle", "upper", "lower", "left", "right", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be construed as a limitation of the present utility model.
[0032] As Figure 1As shown in Fig. 3, the specific solution of the embodiment is as follows: It includes a highway ruler 1. The highway ruler 1 is in two sections, and the two sections of the highway ruler 1 are connected by a hinge seat. Bubble levels 101 are installed on both sections of the highway ruler 1. A bubble level 101 is a tool used to detect the levelness of an object. It usually consists of a transparent tube and a glass tube filled with liquid and a bubble. When the object is level, the bubble will float at the central position in the middle of the liquid. By observing the position of the bubble, it can be judged whether the object is level, and then adjustments can be made;
[0033] A chute 102 is opened on the side wall of the highway ruler 1. A sliding seat 103 is slidably connected to the chute 102. The sliding seat 103 is in an L shape. A through hole is opened on the surface of the sliding seat 103. A laser distance sensor 104 is fixedly connected to the surface of the sliding seat 103. The laser head of the laser distance sensor 104 is located inside the through hole. A laser distance sensor 104 is a device that uses laser technology for distance measurement. It emits a beam of laser to the target object and then receives the reflected laser signal. By measuring the time delay or phase difference of the laser, the distance between the target object and the sensor is calculated.
[0034] A feeler gauge 2 is installed on the highway ruler 1. The feeler gauge 2 is in a right trapezoid shape. A scale table is provided on the inclined surface of the feeler gauge 2. The setting of the scale table facilitates the user to take readings. Two iron sheets 201 are fixedly connected to the surface of the feeler gauge 2 and are symmetrically distributed. A handle 202 is fixedly connected to the outside of the feeler gauge 2. A connecting component 3 is provided between the highway ruler 1 and the feeler gauge 2.
[0035] The connecting component 3 includes an installation groove 31 opened at the lower end of the highway ruler 1. A directional groove 311 and a slideway 312 are opened on the side wall of the installation groove 31. The directional groove 311 and the slideway 312 have the same length. The directional groove 311 and the slideway 312 are in the same horizontal position. An installation seat 32 is movably connected inside the installation groove 31. A directional seat 321 is fixedly connected to the outside of the installation seat 32. The directional seat 321 slides inside the directional groove 311. The installation seat 32 is a rectangular block, and the lower end of the installation seat 32 is open;
[0036] A fastener 33 is provided between the mounting base 32 and the highway ruler 1. The fastener 33 includes a connecting rod 331 fixedly installed on the outer side of the mounting base 32. The connecting rod 331 is located inside the slideway 312. One end of the connecting rod 331 away from the mounting base 32 is threadedly connected with a fastening sleeve 332. A non-slip pad is fixedly connected to one end of the fastening sleeve 332 close to the highway ruler 1. A winding disc 34 is movably installed inside the mounting base 32. Both sides of the winding disc 34 are fixedly connected with rotating shafts 341. The other ends of the rotating shafts 341 are movably connected to the inner side wall of the mounting base 32 respectively. A torsion spring 35 is installed between the winding disc 34 and the side wall of the mounting base 32. The number of the torsion springs 35 is two, and both are located outside the rotating shafts 341. A fixing plate 36 is fixedly connected to the inner side wall of the mounting base 32. The fixing plate 36 is located below the winding disc 34. A through hole is formed on the surface of the fixing plate 36. The through hole is located at the middle position of the fixing plate 36. Two magnets 361 are fixedly connected to one end of the fixing plate 36 away from the winding disc 34, and are symmetrically distributed. A connecting rope 37 passing through the fixing plate 36 is fixedly connected between the winding disc 34 and the feeler gauge 2. The connecting rope 37 is wound on the winding disc 34 and is located inside the through hole.
[0037] The working principle of the above embodiment is as follows:
[0038] When the feeler gauge 2 needs to be used, manually rotate the fastening sleeve 332 to separate the non-slip pad on the outer side of the fastening sleeve 332 from the highway ruler 1. With the cooperation of the orientation groove 311 and the orientation seat 321, the fastening sleeve 332 can drive the mounting base 32 inside the mounting groove 31 to move in position. After moving to the specified position, pull down the feeler gauge 2 through the handle 202. The lowered feeler gauge 2 pulls the connecting rope 37. With the cooperation of the rotating shaft 341, the winding disc 34 pays out the rope; and a torsion spring 35 is arranged outside the rotating shaft 341, so that the feeler gauge 2 can be conveniently retracted.
