Besides, a strut spring 2234 is sleeved on the surface of the strut 2233, the bottom end of the strut spring 2234 is welded to the upper surface of the buffer block 2231, the top end of the strut spring 2234 is welded to the bottom surface of the stamping seat 220, when the buffer block 2231 slides with the strut 2233, an extrusion force is formed on the strut spring 2234, so that the strut spring 2234 is compressed, and when the buffer block 2231 contacts with the stamping part, the stamping part can be further stabilized by an elastic force generated by the compression of the strut spring 2234.

Furthermore, both the front end and the side surface of the limiting rod 124 are provided with a fixing plate 1241, a threaded through hole 1242 is formed in the fixing plate 1241, the upper surface of the movable plate 121 is located on the side surface of the stamping groove 1210 and is provided with a threaded hole 1211, a bolt 1243 is connected between the threaded hole 1211 and the threaded through hole 1242 in a threaded manner, and the movable plate 121 and the clamping device 122 are conveniently connected and fixed through the connection between the threaded hole 1211 and the threaded through hole 1242.

Specifically, be connected with connecting rod 123 between two sliders 125, connecting rod 123 both ends all are equipped with sliding pin 1231, spout 1250 has been seted up to the inside of slider 125, sliding pin 1231 is located inside spout 1250, and with spout 1250 sliding connection, be convenient for use two clamping device 122 simultaneously through the connecting rod 123 that sets up, played and used manpower sparingly, the effect of lifting efficiency, through sliding connection between connecting rod 123 and two sliders 125, be convenient for cooperate the regulation of interval between two clamping device 122.

In addition, the supporting seat 111 is installed at the left end of the installation seat 110, the motor 112 is installed on the upper surface of the supporting seat 111, the motor bevel gear 1121 is fixedly connected to an output shaft of the motor 112, the rolling rod 1312 penetrates through the rotation hole 1321 at the rear end of the rolling rod 1312 to be provided with the rolling rod bevel gear 1313, the rolling rod bevel gear 1313 is meshed with the motor bevel gear 1121, and the rolling rod 1312 can be driven to rotate through the work of the motor 112, so that the fixing frame 131 is driven to work, the labor is saved, and the efficiency is improved.

Besides, the upper surface center department of supporting seat 111 is equipped with mounting panel 1111, and mounting panel 1111 is inside to have seted up installing port 1112, through bolt fixed connection between motor 112 and the mounting panel 1111, and the output shaft of motor 112 runs through mounting panel 1111 and motor 112's relation of connection, is convenient for stabilize motor 112, avoids its during operation to take place to slide, leads to dropping, influences work.

Further, the right side surface of the mounting seat 110 is fixedly connected with a protective shell 113, the protective shell 113 is of an internal cavity structure, and the motor bevel gear 1121 and the rolling rod bevel gear 1313 are both located inside the protective shell 113, so that the motor bevel gear 1121 and the rolling rod bevel gear 1313 are protected.

The foregoing shows and describes the general principles, essential features, and advantages of the invention.
