[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0025] The utility model provides an artificial line drawing assistant, such as Figure 1-2 As shown, it includes: two support rods 1, a movable wire take-up device 2, a slider 6, a wire 7 and a photoelectric rangefinder.

[0026] For ease of understanding, the two support rods 1 are respectively defined as a first support rod 1 and a second support rod 1 .

[0027] The movable wire take-up device 2 is slidably disposed on the first support rod 1 along the length direction of the first support rod 1 , and the movable wire take-up device 2 is constructed to have a wire taking-up function.

[0028] The sliding block 6 is slidably disposed on the second supporting rod 1 .

[0029] The wire 7 is used in conjunction with the movable wire take-up device 2 , and one end of the wire 7 extends out from the movable wire take-up device 2 and is fixedly connected to the slider 6 .

[0030] The photoelectric rangefinder includes a main structure and a target surface. The main structure is integrated with the movable wire take-up device 2. The target surface is arranged on the slider 6. In some embodiments, when the side of the slider 6 facing the main structure can be used as a reflective surface, there is no need to additionally set a target surface on the slider 6. The side of the slider 6 can be directly used as the target surface. The photoelectric rangefinder is used to measure the distance between the slider 6 and the main structure.

[0031] The support rod 1 is used to provide support for the movable wire take-up device 2 and the slider 6. When in use, the wire 7 is released from the movable wire take-up device 2 to a required length, and then the two support rods 1 are relatively placed on both sides of the area to be marked. Preferably, the wire 7 is in a straight state, and then the line is drawn on the ground manually or by pulling the wire 7 upward so that the wire 7 leaves a mark on the soft soil instead of drawing the line.

[0032] Compared with the prior art, the advantage of the present invention is that a photoelectric distance meter is used to measure the distance information between the slider 6 and the movable wire take-up device 2, that is, the wire length between the two, without the need for manual measurement. The photoelectric distance meter has high measurement accuracy, overcoming the defect of the prior art that simple tools are prone to measurement errors.

[0033] In order to facilitate the staff in some embodiments, the embodiments of the utility model further include a display 3, which is arranged on the movable wire receiver 2 and is communicatively connected with the photoelectric rangefinder to display distance information.

[0034] This embodiment facilitates the staff to view the distance information, thereby improving work efficiency. In this embodiment, the information transmission between the display 3 and the photoelectric distance meter can adopt the scheme in the prior art, and the utility model does not make any improvement on this.

[0035] In some embodiments, the movable wire take-up device 2 is an electric wire take-up device, and the power source of the electric wire take-up device is a servo motor or motor that can rotate forward and reverse. A small motor or motor can be used. The actuator is a reel, and the reel is connected to the output shaft of the servo motor or motor. The servo motor or motor drives the reel to rotate forward to wind up the wire and reverse to pay out the wire, or rotate forward to pay out the wire and reverse to wind up the wire. The servo motor and the reel are wrapped with an outer shell, and a wire passing hole is provided on the outer shell. One end of the wire extends out of the wire passing hole and is fixedly connected to the slider 6.

[0036] In order to meet more usage scenarios, in some embodiments, two active wire receivers 2 are provided, and two sliders 6 are provided. A control button 4 is provided on one of the active wire receivers 2, and the control button 4 controls the operation of the two active wire receivers 2. It can be understood that a control module must be provided in the active wire receiver 2, such as a chip, etc. to cooperate with the control button 4 to achieve the purpose of controlling the operation of the electric wire receiver by pressing the control button 4. This part belongs to mature technology and the utility model does not make any improvements on this.

[0037] Of course, multiple movable wire take-ups 2 and sliders 6 may be provided, for example, three, four, etc., to meet more usage scenarios.

[0038] In this embodiment, no matter how many movable wire take-ups 2 are provided, only one of the movable wire take-ups 2 needs to be integrated with a photoelectric distance meter, because in the use state, the two support rods 1 are provided in parallel and the distance between the two is always equal.

[0039] Specifically, when a shell is provided, the main structure of the photoelectric rangefinder is integrated inside or outside the shell. When integrated inside, it is necessary to open an inlet and outlet light hole at a corresponding position on the shell so that light can shine on the target surface on the slider 6 after coming out of the shell.

[0040] The photoelectric rangefinder is preferably a laser rangefinder, which also includes a laser receiving component to receive the laser reflected from the target surface, and then calculate the distance information according to its own built-in logic and transmit it to the display for display.

[0041] In some embodiments, the bottom of the movable wire winder 2 and the slider 6 are both constructed with a conical structure 5 for inserting into the soil to achieve positioning; the tops are both constructed with a handle structure, the top of the handle structure on the movable wire winder 2 is provided with a positioning column, and the top of the handle structure on the slider 6 is provided with a positioning hole, the heights of the positioning column and the positioning hole are flush, and when limiting the device, after the line is reeled in, the two supports can be placed.

[0042] This embodiment utilizes the structural configuration of the movable wire take-up device 2 and the slider 6 for positioning.

[0043] In some embodiments, scale grooves are sequentially arranged on the support rod 1 along its length direction, and the scales on the two support rods 1 correspond to each other.

[0044] Embodiment 2

[0045] On the basis of the above embodiments, in order to maintain the relative position between the movable wire winder 2 and the slider 6 and the support rod 1, the movable wire winder 2 and the slider 6 in the embodiment of the utility model are integrated with a snap-fit ​​structure, which can be snapped into the scale groove to fix the movable wire winder 2 and the slider 6 when the snap-fit ​​structure is engaged.

[0046] The buckle structures in this embodiment are integrated on one side or both sides of the movable wire take-up device 2 and the slider 6 , so that the relative positions between the movable wire take-up device 2 and the support rod 1 , and between the slider 6 and the support rod 1 can be fixed.

[0047] Specifically, the buckle structure can be a card, a snap ring, etc. The card is configured to be movably arranged on both sides of the shell. The card can move toward the scale groove and be clamped after moving to the scale groove. It can also move in the direction away from the scale groove and be in a clamped state after moving out of the scale groove.

[0048] The present invention uses specific examples to illustrate the principle and implementation of the present invention. The above examples are only used to help understand the method and core idea of ​​the present invention. At the same time, for those skilled in the art, according to the idea of ​​the present invention, there will be changes in the specific implementation and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
