On the basis of the above structure, the driving disc 6 is eccentrically arranged outside the front end of the transverse shaft 5 , and an annular groove 7 is formed on the outer wall of the front end of the driving disc 6 .

In this embodiment, the driving disk 6 eccentrically arranged outside the front end of the horizontal shaft 5 facilitates the control of the lifting and lowering of the punching assembly 8 to perform the punching operation.

On the basis of the above structure, the punching assembly 8 includes an L-shaped rod 81, a mounting rod 82, a limiting rod 83, a movable block 84, a punching needle 85, a connecting sleeve 86, a mounting ring 87 and a support rod 88. The mounting rod 82 is welded and fixed at the bottom of the L-shaped rod 81. Through grooves are symmetrically opened inside the left and right ends of the mounting rod 82. The limiting rods 83 are fixed in the two through grooves. The outer sliding sleeve of the limiting rod 83 is provided with a movable block 84. The bottom of the two movable blocks 84 and the middle of the bottom end of the mounting rod 82 are fixed with punching needles 85. The outer threaded sleeve of the vertical section of the L-shaped rod 81 is provided with a connecting sleeve 86. The bottom outer bearing sleeve of the connecting sleeve 86 is provided with a mounting ring 87. The left and right outer walls of the mounting ring 87 are symmetrically hinged with support rods 88, and the other ends of the two support rods 88 are respectively hinged to the tops of the two movable blocks 84.

In this embodiment, the punching needles 85 are fixed to the bottom of the two movable blocks 84 and the middle of the bottom end of the mounting rod 82, so that multiple holes can be punched on the contract paper at the same time, with fast hole-making speed and high efficiency.

Based on the above structure, the top horizontal section of the L-shaped rod 81 is guided and slidably located in the annular groove 7 opened on the outer wall of the driving disk 6, and multiple punching needles 85 are arranged at equal intervals along a horizontal straight line. The two movable blocks 84 are linked to each other and the sliding directions are always opposite.

In this embodiment, the spacing between the three punching needles 85 can be conveniently adjusted by using two movable blocks 84 that always move synchronously in opposite directions, so that the device can quickly adjust the punching position according to the actual size of the contract paper.

On the basis of the above structure, the extrusion positioning assembly 9 includes a pressing frame 91, a rubber pad 92, a vertical rod 93, a spring 94 and a bracket 95. The pressing frame 91 is located directly below the mounting rod 82. The rubber pad 92 is bonded to the bottom of the pressing frame 91. Vertical rods 93 are welded and fixed above the left and right ends of the pressing frame 91. The outer sides of the two vertical rods 93 are movably sleeved with springs 94 and brackets 95. One end of the bracket 95 is welded and fixed to the outer wall of the vertical plate 2.

In this embodiment, the provision of the spring 94 and the pressure frame 91 facilitates auxiliary pressing of the contract paper before punching, without the need for manual pressure, making the punching of the device safer.

On the basis of the above structure, the left and right ends of the mounting rod 82 are movably mounted on the outsides of the left and right vertical rods 93 , and the two ends of the spring 94 are fixedly connected to the mounting rod 82 and the pressing frame 91 , respectively.

In this embodiment, the vertical rod 93 and the bracket 95 are provided to improve the stability of the installation rod 82 and the pressing frame 91 during the lifting and lowering adjustment process.

The working principle of the utility model is as follows:

When in use, firstly, all the papers of the contract are neatly stacked and placed between the bottom plate 1 and the pressing frame 91, and one end of the paper of the contract is in contact with the outer wall of the front end of the vertical plate 2, so as to ensure that all the holes are located in the same straight line during the subsequent punching. Then, the motor 4 fixed to the upper end of the support frame 3 can be started to control the rotation of the horizontal axis 5 and the eccentrically arranged driving disk 6 fixed to the outer side of its front end. The annular groove 7 opened on the outer wall of the driving disk 6 can squeeze and push the L-shaped rod 81 to drive the entire punching assembly 8, the pressing frame 91, and the vertical rod 93 to move downward stably and synchronously under the action of the bracket 95. The pressing frame 91 can first be in contact with the paper of the contract. When the punching assembly 8 continues to move downward relative to the pressing frame 91 to punch holes, the spring 94 can continuously apply pressure to the pressing frame 91, so as to facilitate the strong pressing of the paper of the contract, so that the device has an auxiliary paper pressing positioning function, and the three equidistantly arranged punching needles 85 are convenient for punching holes in multiple places of the contract at the same time, and the punching is faster;

Before punching, the connecting sleeve 86 threadedly connected to the outer side of the vertical section of the L-shaped rod 81 can be manually rotated to drive the mounting ring 87 to move downward synchronously. At this time, the two movable blocks 84 can be pushed to move synchronously along the limiting rod 83 in the direction away from each other through the two support rods 88, and the spacing between the three punching needles 85 can be adjusted, so that the device can quickly adjust the punching position according to the actual size of the contract paper, and the device is more practical.
