[0075] Furthermore, the support unit 200 includes a first base 201 and a nut 204, a support frame 202 arranged on the upper surface of the first base 201, and a second base 203 arranged on one side of the first base 201; the first base 201 includes a support block 201 a arranged on its end surface; and the connecting plate 101 is arranged on one side of the support frame 202.

[0076] Preferably, the first base 201 and the second base 203 cooperate with each other to better support the two ends of the blade body m; the support block 201 a cooperates with the outer wall of the blade body, thereby supporting the blade body; the connecting plate 101 is located on one side of the support frame 202, thereby ensuring that the connecting plate 101 can be pressed between the nut 204 and the support frame 202.

[0077] When in use, the operator uses the weight device to place the blade body m between the first base 201 and the second base 203; the blade body m can be supported by the first base 201 and the second base 203; then, in order to facilitate the fixing of the blade body m, the connecting plate 101 can be rotated so that the end of the connecting plate 101 is flipped to the inner side of the screw n, and then the position of the connecting plate 101 and the first base 201 is fixed according to the above steps; when it is necessary to release the limit of the transmission member 104, the button 108b-2 is pushed, and then the button 108b-2 can drive the top block 108b-1 to move, so that the end face of the top block 108b-1 contacts the inner wall of the groove 108a-1, and then the limit rod 108a is driven to move with the movement of the top block 108b-1, so that the end of the limit rod 108a is immersed in the sliding sleeve 1 03c inner side; as the end of the limit rod 108a moves away from the inner side of the limit groove 104a-1, the push rod 104a is no longer restricted, and then the first spring 104b pushes the push rod 104a to reset, so that the push rod 104a drives the limit plate 103 to flip, thereby ensuring that the end of the limit plate 103 is away from the inner side of the slot 101a; and the end of the limit rod 108a is set to an inclined structure, so that when the limit rod 108a flips, the inclined surface of the limit rod 108a contacts the end of the push rod 104a, which can make the limit rod 108a be pressed and moved to the inner side of the sliding sleeve 103c. When the position of the limit rod 108a corresponds to the position of the limit groove 104a-1, the limit rod 108a is pushed to be stuck in the inner side of the limit groove 104a-1 under the action of the rebound force of the second spring 108a-2, thereby fixing the position of the transmission member 104.

[0078] In summary, the present invention can pre-fix the position of the connecting plate by setting a limit unit; thereby freeing the operator's hands, making it easier for the operator to operate, and making it easier and more convenient for the staff to use the device; at the same time, when the connecting plate is pre-fixed, the warning piece will form a passage, so that the indicator light will emit light, further serving as a warning for the staff in the dark.
