Obviously, the described embodiments are only some embodiments of the present application, not all embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0036] As shown in Figs. 1-3 The asphalt trimmer of the present application comprises a blade 1, a handle 2, a connecting piece 3 and a temperature controller 4.

[0037] As shown in Fig. 1As shown, there are two blades 1 arranged opposite each other, and each blade 1 is equipped with a heating wire; there is one handle 2 on each of the two blades 1, and the two handles 2 are crossed over each other, and the intersection of the two handles 2 is connected by a rotating shaft.

[0038] As described above, each of the two blades 1 is connected to a handle 2, so that the asphalt can be sheared through the handle 2; the heating wire is used to heat the blades 1, thereby ensuring that the blades 1 have a specific temperature and thus ensuring that the blades 1 have good trimming performance.

[0039] Connector 3 is connected to the pivot at the intersection of the two handles 2; thermostat 4 is connected to connector 3 and electrically connected to heating wire;

[0040] As described above, the two handles 2 rotate at the pivot joint to perform the shearing action. A connector 3 is provided on the pivot, and the temperature controller 4 is installed through the connector 3. In this way, the temperature control component does not need to be integrated into the handle 2, but is set as an independent structure. This avoids the problem of structural complexity caused by integration with the handle 2, and has enough integration space to accommodate several components such as the temperature control circuit board. This not only improves the convenience of integration and operation, but also does not interfere with the normal use of the trimmer.

[0041] In some embodiments, the thermostat 4 may be connected and fixed to one of the handles 2 by fasteners, wherein the connector 3 is rotatably connected to the shaft to avoid interference with the shearing action.

[0042] like Fig. 1 As shown, the handle 2 includes a connecting rod 21, a connecting ring 22, and a grip 23. One end of the connecting rod 21 is connected to the blade 1, and the other end is connected to the connecting ring 22. One end of the grip 23 is connected to the connecting ring 22. The connecting rings 22 of the two handles 2 are connected by a pivot. The connector 3 is connected to the connecting ring 22 by a pivot.

[0043] As described above, the handle 2 connects the connecting rod 21 and the grip 23 via the connecting ring 22. The connecting ring 22 is used to connect the rotating shaft, and then connects to the connector 3 via the rotating shaft. The connector 3 is set as a U-shaped structure and is connected in series with the connecting ring 22 of the two handles 2 via the rotating shaft.

[0044] The blade 1 is connected to the connecting rod 21, and the handle 23 is used for operation.

[0045] like Fig. 1As shown, the temperature controller 4 comprises a temperature controller body 41 and an LED display screen 42, wherein one end of the temperature controller body 41 is connected with the connecting piece 3, and the temperature controller body 41 is internally provided with a temperature control circuit board, which is electrically connected with the heating wire; the LED display screen 42 is arranged on the temperature controller body 41 and electrically connected with the temperature control circuit board.

[0046] As shown in the above structure, the temperature controller body 41 is connected with the connecting piece 3, the upper portion of which is provided with the LED display screen 42 and connected with the internal temperature control circuit board, so that the heating information can be displayed through the LED display screen 42, which has the advantage of convenient observation.

[0047] As shown in the above structure, the temperature controller body 41 is connected with the connecting piece 3, the upper portion of which is provided with the LED display screen 42 and connected with the internal temperature control circuit board, so that the heating information can be displayed through the LED display screen 42, which has the advantage of convenient observation. Fig. 1 As shown, the temperature controller 4 further comprises an adjusting knob 43, which is rotationally connected with the temperature control circuit board;

[0048] As shown in the above structure, in order to facilitate the control of the temperature of the heating wire in the blade 1, the adjusting knob 43 is used for control, specifically, the adjusting knob 43 is rotationally connected with the temperature control circuit board in the temperature controller body 41, so as to realize the temperature regulation and control;

[0049] In the illustration, the adjusting knob 43 contacts the temperature controller body 41, and in fact, it is connected with the temperature control circuit board, which is a conventional knob structure.

[0050] As shown in the above structure, the temperature controller 4 further comprises an adjusting knob 43, which is rotationally connected with the temperature control circuit board; Figs. 1-3 As shown, the temperature controller 4 further comprises an adjusting knob 43, which is rotationally connected with the temperature control circuit board;

[0051] As shown in the above structure, the temperature controller 4 further comprises an adjusting knob 43, which is rotationally connected with the temperature control circuit board;

[0053] Further, the surface of the handle 23 is provided with an insulating layer, so as to improve the safety of application and avoid personal injury caused by electric leakage when the temperature controller 4 is damaged.

[0054] As shown in the above structure, the temperature controller 4 further comprises an adjusting knob 43, which is rotationally connected with the temperature control circuit board; Fig. 1 As shown, the blade 1 comprises a cutting piece 11 and a ring piece 12, wherein the cutting piece 11 is in a semi-ring structure; the ring piece 12 is arranged on the cutting piece 11 and connected with the handle 2;

[0055] As shown in the above structure, the two blades 1 are in a semi-ring structure, which relies on the cutting piece 11 to trim the asphalt, and the ring piece 12 can block the asphalt from falling, so as to facilitate subsequent collection and processing, so as to ensure the cleanliness of the environment.

[0056] After the two blades 1 are combined, they are in an oval ring structure;

[0057] As the above structure, the two blades 1 constitute an elliptical ring structure, so that the shearing points of the two blades 1 are close to each other, facilitating fast shearing operation, and more asphalt can be accommodated,

[0058] Specifically, the heating wire is arranged on the surface of the slice 11 away from the ring piece 12.

[0059] Specific implementation steps:

[0060] During the test, the asphalt sample is clamped between two parallel metal test plates, one of which is driven by an air motor to rotate at a constant angular velocity, and the other is fixed. By measuring the applied shear stress and the deformation of the sample, the complex shear modulus and the phase angle can be calculated to characterize the elastic and viscous properties of the material, and then to evaluate its rheological behavior under different conditions. The sample is usually shaped in the test mold and placed between the two metal test plates. The instrument controls the thickness of the sample by adjusting the distance between the metal sample plates, usually to 1mm or 2mm, to ensure that the sample is tightly clamped between the metal test plates and the accuracy of the test. Since the thickness of the sample shaped in the test mold is usually slightly larger than the controlled thickness, part of the sample will overflow the outside of the metal sample plate, which requires trimming of the overflowed part. At this time, the blade 1 is heated by the temperature controller 4, and then the handle 2 is operated to trim the overflowed asphalt with the slice 11 of the blade 1.

[0061] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
