Therefore, the drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0024] See also Figure 1 and Figure 2 Since it is inconvenient to get electricity at the construction site, there are many inconveniences when sampling steel bars through large-scale cutting equipment. Therefore, the utility model provides a small and handheld steel bar sampling equipment, which can be easily carried and can be connected to an external mobile power supply to solve the problems existing in the prior art. The steel bar sampling equipment includes a cutting disc 10, which is rotatably mounted on a frame 20, and a driving mechanism drives the cutting disc 10 to rotate; a positioning slot 30 is mounted on the side of the frame 20 and is used to position the steel bars to be cut, and the disc surface of the cutting disc 10 is perpendicular to the length direction of the positioning slot 30; the frame 20 is mounted on a swing mechanism, and the swing mechanism drives the cutting disc 10 to move closer to or farther from the positioning slot 30.

[0025] In one embodiment, a structure that is easy to replace can be used between the cutting disc 10 and the frame 20. The cutting disc 10 is a common grinding wheel disc in the prior art, which is low in cost and has a good effect on cutting steel bars. It can ensure the flatness of one end of the steel bar to ensure the reliability of subsequent sample testing.

[0026] In one embodiment, in order to facilitate the measurement of the length of the steel bar placed in the positioning slot 30, that is, the length of the cut steel bar sample, a scale 31 is provided on the positioning slot 30, and the scale 31 is arranged along the length direction of the positioning slot 30.

[0027] In one embodiment, the scale 31 is made of stainless steel to prevent the scale 31 from being deformed.

[0028] In one embodiment, in order to locate one end of the steel bar to be sampled, a positioning top plate 32 is provided at one end of the positioning slot 30. The positioning top plate 32 is slidably disposed on the positioning slot 30 via a sliding rod 321. The sliding rod 321 is arranged parallel to the scale 31, and the scale 31 is fixed on the positioning top plate 32.

[0029] In one embodiment, during actual sampling, one end of the steel bar to be sampled is clamped in the positioning slot 30 so that one end of the steel bar rests on the positioning top plate 32. When the length on the scale 31 matches the length of the steel bar sample, the driving mechanism and the swing mechanism are started to cut the steel bars on the positioning steel slot 30, so that the required steel bar sample can be obtained on the positioning slot 30.

[0030] In one embodiment, a locking mechanism is provided on the positioning slot 30, and the locking mechanism may be a locking nut. When the length displayed on the scale 31 is consistent with the set sample length, the locking nut is screwed so that the locking nut abuts against the slide rod 321, thereby locking the position of the positioning top plate 32.

The center of the driving gear 43 is connected to the power shaft of a swing motor 44, and the swing motor 44 is mounted on the mounting frame 40.

[0036] In one embodiment, in order to implement the swinging of the cutting disk 10 so that the cutting disk 10 can move closer to or further away from the positioning slot 30, the swing motor 44 is started so that the swing frame 23 is located on the mounting frame 40 and is swingingly loaded, thereby allowing the cutting disk 10 to move closer to or further away from the positioning slot 30.

[0037] In one embodiment, in order to ensure the safety of the sampling device, a shield 45 is extended from the mounting frame 40 , and the shield 45 is disposed outside the cutting disc 10 .

[0038] In one embodiment, in order to facilitate handheld operation of the sampling device, a handle 46 is provided on the mounting frame 40 .
