Two stretching blocks 5 are set between the outer surfaces of the bidirectional screw rod 3 and the cross bar 4. Steel plates 6 are set on the tops of the two stretching blocks 5. When the two stretching blocks 5 move in opposite directions, the steel plates 6 on their tops can be stretched. A pressing mechanism 7 is set on the tops of the two stretching blocks 5 to limit and press the steel plates 6.

[0024] The clamping mechanism 7 includes a U-shaped frame 71 fixed to the top of the stretching block 5, and the top of the U-shaped frame 71 is slidably connected to a vertical rod 72, the bottom end of the vertical rod 72 passes through the U-shaped frame 71 and extends to the outside of the U-shaped frame 71, the bottom end of the vertical rod 72 is fixed with a horizontal plate 73, the bottom of the horizontal plate 73 is fixed with an insertion rod 74, and the top of the vertical rod 72 is fixed with a handle 75. A through hole 76 is opened through the top of the steel plate 6, and a slot 77 is opened at the top of the stretching block 5. The bottom end of the insertion rod 74 passes through the through hole 76 and extends to the inside of the slot 77. A spring 78 is fixed to the outer surface of the vertical rod 72, and the insertion rod 74 is matched with the size of the through hole 76 and the slot 77. After the insertion rod 74 is inserted into the through hole 76 and the slot 77, the steel plate 6 can be limited.

[0025] The top of spring 1 78 is fixed to the bottom of U-shaped frame 71, the bottom of spring 1 78 is fixed to the top of cross plate 73, the outer surface of bidirectional screw rod 3 is threadedly connected to the inner surface of two stretching blocks 5, and the outer surface of cross bar 4 is slidably connected to the inner surface of stretching block 5.

[0026] By setting the clamping mechanism 7, the clamping limit of the steel plate 6 is achieved, which makes it convenient to fix the steel plate 6 on the two stretching blocks 5 and then perform the stretching operation, thereby improving the yield rate of the steel plate 6 after stretching. The clamping operation is simple and very practical.

It is controlled by an external switch and electrically connected to an external power supply. The motor 8 drives the bidirectional screw 3 to rotate. The output end of the motor 8 is fixed to one end of the bidirectional screw 3 through a coupling.

[0028] Example 2

[0029] Based on Example 1, see Figure 3 As shown, one side of the L-shaped seat 1 and the fixed seat 2 is provided with an anti-over-stretching component 9 for limiting the stretching block 5. The anti-over-stretching component 9 includes a fixed tube 91 fixed on one side of the L-shaped seat 1 and the fixed seat 2, and one end of the fixed tube 91 is slidably connected to a moving rod 92.
