Abstract
Description
Technical Field
[0001] The utility model relates to a device suitable for punching holes for file binding by a hand electric drill, and particularly relates to a punching device for temporary binding of documents by water conservancy construction units. Background Art
[0002] Often, water conservancy construction units are located in remote areas, and it is not very convenient to purchase various materials. When a small amount of materials needs to be temporarily bound, since the unit has a lot of hand drills, they can be used to punch holes for binding materials. After use, they can be quickly removed without damaging the original mechanical properties of the hand drill. It is easy to install and disassemble and is more flexible to use. Summary of the invention
[0003] The utility model aims to provide a three-hole binding punching device which is low in cost, easy to install and use, and can be simply assembled and used by only finding three hand electric drills as punching drill bits.
[0004] The utility model is achieved in this way:
[0005] The three-hole binding and punching device comprises an upper and a lower operating table. The upper operating table 17 is a long horizontal plate with a horizontal through hole at each end and the middle thereof. There is a boss on the middle horizontal through hole, and a handle seat is provided on one side of the boss. A sleeve 20 is fixedly connected to the middle of the left end of the lower operating table 7. A groove 5 is provided at the right end of the lower operating table 7 and is parallel to the upper operating table 17. Screw holes are provided on opposite sides of the groove 5 to cooperate with the screw 4. A hole is provided on the pressure plate 6 to be sleeved on the screw 4. The text to be stapled is located between the pressure plate 6 and the lower operating table. The staple line is located on the axis of the groove 5. The lower part of the middle part of the upper operating table 17 is hinged to the upper end of the piston rod. The piston rod is fixed The fixedly connected piston is movably matched with the sleeve 20 on the lower operating platform 7, the lower end of the piston rod is connected to the sleeve 20 on the lower operating platform 7 through a spring 14, the handle 1 is connected to the hand peg of the upper operating platform 17 through a screw 9, one end of the three parallel horizontal rods 15 passing through the horizontal through hole is threaded and respectively connected with the first and second nuts 10 and 8 on the left and right sides of the upper operating platform 17, the other end of the horizontal rod 15 is fixedly connected to the hoop, the hand peg is located between the two horizontal rods 15, and there is a horizontal fitting piece 16 on the hoop, and the hoop screw 3 tightens the hoop horizontal fitting piece 16 to fix the drill bit in the hoop to the hand drill 2 vertically downward.
[0006] When drilling, the operator presses the handle down, and the upper operating table automatically returns to its original position after drilling is completed.
[0007] The advantages of the utility model are as follows:
[0008] Since water conservancy construction units have a lot of hand drills, they can easily assemble and use 3 of them at random, and can be quickly disassembled after use without damaging the original mechanical properties of the hand drill. It is easy to install and disassemble and is more flexible to use.
[0009] The utility model has the advantages of simple processing, easy operation, low processing cost, and reusability, and effectively solves the problem of lack of punching device for temporary binding materials of water conservancy construction units. The device is safe, reliable, and technically feasible. BRIEF DESCRIPTION OF THE DRAWINGS
[0010] Figure 1 It is a structural diagram of the utility model.
[0011] Figure 2 for Figure 1 Top view of the . DETAILED DESCRIPTION
[0012] The three-hole binding and punching device comprises an upper and a lower operating table. The upper operating table 17 is a long horizontal plate with a horizontal through hole at each end and in the middle. There is a boss on the middle horizontal through hole, and a handle seat is provided on one side of the boss. A sleeve 20 is fixedly connected to the middle of the left end of the lower operating table 7. A groove 5 is provided at the right end of the lower operating table 7 and is parallel to the upper operating table 17. Screw holes are provided on opposite sides of the groove 5 to cooperate with the screw 4. A hole is provided on the pressure plate 6 to be sleeved on the screw 4. The text to be stapled is located between the pressure plate 6 and the lower operating table, and the staple line is located on the axis of the groove 5. The lower part of the middle part of the upper operating table 17 is hinged to the upper end of the piston rod, and the piston rod is fixedly connected to the The piston is movably matched with the sleeve 20 on the lower operating platform 7, the lower end of the piston rod is connected to the sleeve 20 on the lower operating platform 7 through a spring 14, the handle 1 is fixedly connected or hinged to the hand peg of the upper operating platform 17 through a screw 9, one end of the three horizontal rods 15 passing through the horizontal through hole is threaded and respectively connected to the first and second nuts 10 and 8 on the left and right sides of the upper operating platform 17, the other end of the horizontal rod 15 is fixedly connected to the hoop, the hand peg is located between the two horizontal rods 15, and there is a horizontal fitting piece 16 on the hoop, and the hoop screw 3 tightens the hoop, the horizontal fitting piece 16 fixes the drill bit in the hoop to the hand drill 2 vertically downward.
[0013] The power cord 11 of the hand drill 2 is connected to the plug board 13 through the fixing card 12 .
[0014] When binding is required, the screws 4 on both sides of the slot 5 on the lower operating table 17 drive the pressing plate 6 to fasten the material. When the hand operates the pressing handle 1, the hand drill 3 punches downwards. After the punching is completed, the hand does not press the pressing handle 1 downwards. The pressing handle 1 lifts the hand drill 2 upwards under the action of the spring 14, completing a working cycle. The three-hole binding punching device is simple to make, flexible and convenient to use, has high rigidity, and is very suitable for water conservancy construction units to temporarily bind a small amount of materials or quickly install and use when binding is urgently needed.
