The clamping device further comprises a clamping assembly 15, the clamping assembly 15 comprises an installation rod 151, a placing plate 152, a fifth guide sleeve 153, a pressing plate 154, a second wedge-shaped block 155, a fifth spring 156 and a contact rod 157, the installation rod 151 is symmetrically and fixedly connected to the left side of the outer bottom of the L-shaped frame 92 in a front-back mode, the placing plate 152 is arranged between the left portions of the installation rods 151 on the front side and the rear side, the fifth guide sleeve 153 is fixedly connected to the front side of the bottom of the placing plate 152 in a left-right mode, the pressing plate 154 is slidably arranged on the front portion of the fifth guide sleeve 153, the second wedge-shaped block 155 is fixedly connected to the bottom end of the pressing plate 154, the fifth spring 156 is fixedly connected between the bottom of the fifth guide sleeve 153 and the top of the second wedge-shaped block 155, the fifth spring 156 is wound on the pressing plate 154, the contact rod 157 is fixedly connected to the middle portion of the left side of the fixing frame 1, and the contact rod 157 is matched with the second wedge-shaped block 155.

When the L-shaped frame 92 moves forwards, the L-shaped frame 92 moves forwards to drive the small rack 143 to move forwards, the small rack 143 moves forwards to drive the one-way gear 142 not to rotate, the L-shaped frame 92 drives the small rack 143 to move backwards to reset, the small rack 143 drives the one-way gear 142 to rotate forwards, the one-way gear 142 rotates forwards to drive the telescopic rod 145 to rotate forwards through the bevel gear set 146, the telescopic rod 145 rotates forwards to drive the push wheel 94 to rotate forwards, the push wheel 94 rotates forwards to enable the corner brace to move rightwards for a certain distance, and therefore people do not need to push the corner brace, and labor is saved.

Initially, the fifth spring 156 is in a compressed state, when the L-shaped frame 92 moves forward, the L-shaped frame 92 moves forward to drive the mounting rod 151 to move forward, the mounting rod 151 moves forward to drive the placing plate 152 to move forward, the placing plate 152 moves forward to drive the fifth guide sleeve 153 to move forward, the fifth guide sleeve 153 moves forward to drive the pressing plate 154 to move forward, the pressing plate 154 moves forward to drive the second wedge-shaped block 155 to move forward, the second wedge-shaped block 155 moves forward to separate from the contact rod 157, the pressing plate 154 moves downward to limit the angle code under the action of the fifth spring 156, the L-shaped frame 92 moves backward to reset, the second wedge-shaped block 155 contacts the contact rod 157, the contact rod 157 moves the second wedge-shaped block 155 upward, the fifth spring 156 is compressed, the pressing plate 154 also moves upward to reset, and thus the angle code is prevented from shifting during cutting.

The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present invention, and all the changes or substitutions should be covered within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the appended claims.
