Further improvement: each of the telescopic rods is composed of four sets of rods, and the length of each rod is 125mm. Starting from the front end of the rod, there is a scale line every 25mm. The last tick mark on the rod coincides with the first tick mark on the next set of rods.

Further improvement: the surrounding rod is composed of several connecting rods, one end of the connecting rod is provided with a connecting head, and the other end of the connecting rod is provided with a connecting groove matched with the connecting head.

Further improvement: a chute is provided on the connecting rod, a slider matched with the chute is provided on the connecting rod, each slider is provided with a tape measure, and the chute is There are several hanging loops equidistantly below the .

Further improvement: the length of the connecting rod is 125mm, the distance between two adjacent hanging rings is 25mm, and 1-3 sliders are arranged on the connecting rod.

Further improvement: there are saw teeth at the connection between the chute and the slider.

The advantages of the utility model: firstly, the surrounding rod is composed of a telescopic rod or a connecting rod, so that when not in use, the surrounding rod can be retracted or disassembled, thereby reducing the space occupied by the surrounding rod, and it is also convenient to carry. When used, the fence rods are assembled into quadrats, which are not limited by the height of plants. They can be used not only for herbaceous plants, but also for woody plants, so they have a wide range of adaptability. By sliding the slider on the connecting rod, the size of the quadrat can be changed arbitrarily, which has strong applicability and is more convenient for the investigator's work.

Detailed ways

The present utility model will be described in detail below with reference to the accompanying drawings.

As shown in the figure, a detachable device for surveying plant plots includes surrounding rods 1 located around, and the surrounding rods 1 on adjacent two sides are connected by connecting heads 2, and below the connecting heads 2 are arranged There are telescopic brackets 3.

The enclosing rod 1 on the same side is composed of two telescopic rods 11, the tails of the two telescopic rods 11 on the same side are butted together, and the front ends of the telescopic rods 11 on the adjacent two sides are connected by the connector 2; The telescopic rods 11 are all composed of four sections of sleeve rods 111 , and each section of the sleeve rods 111 protrudes 125mm in length. The last tick mark 112 of 112 coincides with the first tick mark 112 of the next sleeve rod 111 .

The enclosure rod 1 is composed of several connecting rods 12, one end of the connecting rod 12 is provided with a connecting head 121, and the other end of the connecting rod 12 is provided with a connecting groove matched with the connecting head 121; The connecting rod 12 is provided with a chute 4, the connecting rod 12 is provided with a sliding block 5 that cooperates with the sliding groove 4, and each sliding block 5 is provided with a tape measure 6. A number of hanging rings 7 are arranged at an equal distance below the chute 4; the length of the connecting rod 12 is 125 mm, the distance between two adjacent hanging rings 7 is 25 mm, and 1-3 are arranged on the connecting rod 12 Slider 5; there are serrations at the connection between the chute 4 and the slider 5, the serrations can increase the sliding friction between the slider 5 and the chute 4, and prevent the slider 5 from sliding in the chute without external force 4 inside slides.

Its working principle is: firstly, when the enclosing rod 1 selects the telescopic rod 11, the ends of the two telescopic rods 1 on the same side can be connected with the grooves that match with each other, or connected with the iron sheet through magnets. First, according to the size of the sample square, the telescopic rod 11 is stretched to the required length, and then the front ends of the telescopic rods 11 on the adjacent sides are inserted into the connector 2 to form a square sample box. In order to ensure the stability of the sample square frame, the length of the telescopic support 3 can be adjusted at this time to ensure the stability of the sample square frame. size, easy to operate.

When connecting rods 12 are selected for the enclosing rod 1, the specifications of each connecting rod 12 are the same at this time. Among the connecting rods 12 on the same side, two adjacent connecting rods 12 are connected with the connecting head 121 through the matching of the connecting groove. Here, an external thread can be set on the outer wall of the connecting head 121, an internal thread can be set on the inner wall of the connecting groove, or a magnet sheet can be set on the end face of the connecting head 121 and the bottom of the connecting groove, and the connecting rods on the adjacent two sides are also set 12 is also connected to the connecting groove through the connecting head 121. At this time, since the sliding block 5 is set on the connecting rod 12, and the tape measure 6 is also set on the sliding block 5, when the outer sample box is fixed, If you need to set a small sample box in the sample box, you can determine the size of the small sample box by sliding the slider 5 at this time. 61 is pulled out (a hook is set at the front end of the dividing line, which is convenient to hang on the hanging ring), and at the same time, the front end of the dividing line 61 is fixed on the hanging ring 7 of the opposite connecting rod 12, so that the dividing line 61 is in the large sample. Several small sample boxes are planned in the box, so as to meet the investigation needs of the investigator. When it is used up, the hook is directly removed from the hanging ring 7, and the dividing line 61 is retracted by the action of the tape measure 6. It is simple and convenient to operate.
