[0029] like Figure 1 and Figure 2 As shown, the embodiment of the utility model provides a high-toughness manganese steel dovetail clamp, including a first clamping plate 1, the top of the first clamping plate 1 is tightly fitted with the second clamping plate 2, the bottom of the second clamping plate 2 is fixedly equipped with a positioning plate 3, the middle of the positioning plate 3 is provided with a movable groove 6, the inner wall of the movable groove 6 is slidably sleeved with a button 5, the top of the first clamping plate 1 is rotatably connected with an elastic plate 4, the middle of the elastic plate 4 is provided with a mounting groove 8, the inner wall of the mounting groove 8 is sleeved with a retaining spring 9, the outer wall of the retaining spring 9 is in contact with a bayonet 7, and the outer wall of the positioning plate 3 is provided with a connecting groove 10; through the first clamping plate 1, the second clamping plate 2, the positioning plate 3, the elastic plate 4, and the button 5 structure, the user can press the button 5 to make the first clamping plate 1 and the second clamping plate 2 in a movable state during use, so that the dovetail clamp can be adjusted to a horizontal state, which is convenient for the user to store the dovetail clamp, and also reduces the space occupied by the dovetail clamp, thereby improving the practicality and convenience of the dovetail clamp.

[0030] like Figure 1 and Figure 2 As shown, there are four positioning plates 3, which are divided into two groups, and the two groups of positioning plates 3 are symmetrically distributed along the outer wall of the second clamping plate 2. By setting up the two groups of positioning plates 3 structure, the dovetail clamp can be used to position the elastic plate 4 by the two groups of positioning plates 3 during use, so that the first clamping plate 1 and the second clamping plate 2 can rotate. At the same time, it can also ensure that there is sufficient supporting force between the first clamping plate 1 and the second clamping plate 2 to clamp the paper, thereby ensuring the normal use of the dovetail clamp.

[0031] like Figure 2 and Figure 4As shown, the outer wall of the elastic plate 4 is fixedly equipped with a manganese steel bar, and the first clamping plate 1 is rotatably connected to the second clamping plate 2 through the elastic plate 4. Through the set manganese steel bar structure, when the first clamping plate 1 and the second clamping plate 2 are squeezed, the elastic plate 4 and the manganese steel bar can generate a rebound force on the first clamping plate 1 and the second clamping plate 2, ensuring that after the user releases the first clamping plate 1 and the second clamping plate 2, the elastic plate 4 and the manganese steel bar can make the first clamping plate 1 and the second clamping plate 2 fit closely to the paper, thereby achieving the effect of clamping the paper, thereby ensuring the clamping strength of the dovetail clamp.

[0032] like Figure 2 and Figure 3 As shown, the diameter of the bayonet 7 is matched with the diameter of the connecting groove 10, a circular hole is opened on the inner wall of the movable groove 6, and the inner wall of the circular hole is plugged into the outer wall of the bayonet 7, and the outer wall of the bayonet 7 is in conflict with the outer wall of the button 5. Through the provided circular hole, the connecting groove 10 and the button 5 structure, when the bayonet 7 coincides with the position of the circular hole, the elasticity of the retaining spring 9 is used to push the bayonet 7 and the button 5 out together, so that the elastic plate 4 is connected to the positioning plate 3, so that the first clamping plate 1 and the second clamping plate 2 can clamp the paper, and it is also convenient for the user to unfold the dovetail clamp, thereby achieving the effect of facilitating the user's operation.

[0033] like Figure 1 and Figure 3 As shown, when the bayonet 7 is separated from the circular hole, the inner wall of the connecting groove 10 is slidably connected to the outer wall of the bayonet 7. Through the structure of the circular hole and the connecting groove 10, after the user pushes the bayonet 7 out of the circular hole, the user can flip the second clamping plate 2 to make the bayonet 7 slide along the inner wall of the connecting groove 10. At this time, the sliding connection between the bayonet 7 and the connecting groove 10 will make the first clamping plate 1 unable to separate from the second clamping plate 2, so that the dovetail clamp can be kept as a whole and not scattered, and it is convenient for the user to adjust the dovetail clamp to a horizontal state for carrying or storage, thereby improving the convenience of the dovetail clamp.

[0034] like Figure 1 and Figure 4 As shown, the positioning plate 3 and the elastic plate 4 are both made of stainless steel, and the outer walls of the first clamping plate 1 and the second clamping plate 2 are rotatably connected with a pressing rod. The stainless steel material has the characteristics of hardness and elasticity, so that the positioning plate 3 can limit the pin 7 and ensure the tightness of the connection structure between the positioning plate 3 and the elastic plate 4. The elastic plate 4 can rebound the first clamping plate 1 and the second clamping plate 2 due to its elastic characteristics after being squeezed, so that the first clamping plate 1 and the second clamping plate 2 can clamp the paper, and cooperate with the manganese steel bar to strengthen the clamping force of the first clamping plate 1 and the second clamping plate 2 on the paper.

[0035] The technical solution provided by the utility model is that the pressing rod is pressed to increase the angle of the first clamping plate 1 and the second clamping plate 2, and then the dovetail clamp is held with force to clamp the paper. When the dovetail clamp needs to be stored, the button 5 can be pressed to make the latch 7 disengage from the round hole. At this time, the latch 7 cannot be plugged into the round hole under the pressure of the button 5, and can only slide along the inner wall of the connecting groove 10. The user can pull the second clamping plate 2 to flip, thereby changing the angle between the first clamping plate 1 and the second clamping plate 2. After the first clamping plate 1 and the second clamping plate 2 are unfolded, the first clamping plate 1 and the second clamping plate 2 are in a parallel state, thereby achieving the effect of quickly adjusting the dovetail clamp for the user to store it, thereby improving the convenience of the dovetail clamp.

[0036] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the above preferred embodiments of the present invention, and those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0038] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
