DETAILED DESCRIPTION

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0026] like Figure 1 As shown, an accounting book punching machine with a limiting device includes a base 1, a fixed length component 2 is fixedly installed in the middle of the front side of the base 1, a limiting component 3 is fixedly installed in the middle of the upper end of the base 1, and an adjusting hole spacing component 4 is fixedly installed at the rear of the upper end of the base 1.

[0027] The fixed-length component 2 can determine the distance and position of the holes in the account book, and perform precise punching, which can not only ensure the neatness and uniformity of the punching, but also facilitate the subsequent binding of the account book. The limit component 3 can be used to fix the position of the account book before punching, which is suitable for account books of different sizes and improves the accuracy of the device. The hole spacing component 4 can be used to adjust the punching according to actual conditions, so that the distance between the holes on the account book can be quickly and easily adjusted, which is convenient for the subsequent binding of the account book.

[0028] like Figure 3 As shown, the fixed-length component 2 includes a measuring plate 21, and sliders 22 are fixedly installed on the left and right parts of the lower end of the measuring plate 21. A through groove 23 is opened in the middle of the front side of the base 1, and slide grooves are opened on the left and right positions of the bottom of the inner wall of the through groove 23. The lower ends of the two sliders 22 are slidably connected to the inner walls of the two slide grooves. A baffle 24 is fixedly installed on the rear side of the measuring plate 21, and the baffle 24 is located directly behind the base 1. The front part of the upper end of the measuring plate 21 is engraved with scale lines.

[0029] The measuring plate 21 can move in the inner cavity of the through slot 23 through two sliders 22. The two sliders 22 play a limiting role. The measuring plate 21 drives the baffle 24 to approach or move away from the base 1, so that the specific position where the account book needs to be punched can be determined by the numbers on the scale line.

[0030] like Figure 3 and Figure 4As shown, a plurality of linearly arranged fixing holes 25 are provided at the front of the left and right sides of the measuring plate 21, and storage grooves 26 are provided at the front positions of the left and right inner walls of the through slot 23. Positioning plates 27 are rotatably connected to the front positions of the bottoms of the inner walls of the two storage grooves 26, and three fixing columns 28 are fixedly installed on the opposite sides of the two positioning plates 27, and the opposite ends of the six adjacent fixing columns 28 are plugged into the inner walls of the plurality of adjacent fixing holes 25.

[0031] The measurement plate 21 can be fixed or released by the cooperation between the six adjacent fixing columns 28 and the plurality of adjacent fixing holes 25 , which facilitates the work of fixing the length of the measurement plate 21 and the baffle plate 24 .

[0032] like Figure 4 As shown, two limit springs 29 are fixedly installed on the side of the two positioning plates 27 away from each other, and the ends of four adjacent limit springs 29 away from each other are fixedly connected to the front and rear parts of the inner walls of the two storage grooves 26 away from each other.

[0033] Through the four limit springs 29, when pushing the two positioning plates 27, the four limit springs 29 accumulate elastic potential energy at the same time. After the measuring plate 21 moves to the specified position, the two positioning plates 27 are released, and the elastic potential energy of the four limit springs 29 is released, so that the fixing column 28 can be re-matched with the new fixing hole 25.

[0034] like Figure 1 and Figure 2 As shown, the limit assembly 3 includes two mounting plates 31, the lower ends of the two mounting plates 31 are fixedly installed at the left and right positions of the middle part of the upper end of the base 1, and the sides of the two mounting plates 31 away from each other are threadedly connected with adjustment screws 32 that pass through the opposite sides of the two mounting plates 31, and the opposite ends of the two adjustment screws 32 are fixedly installed with limit plates 33.

[0035] The two limit plates 33 are brought closer to each other by two adjusting screws 32, so that account books of different sizes can be limited and fixed.

[0036] like Figure 2 As shown, the hole spacing adjustment component 4 includes a mounting frame 41, the left and right parts of the lower end of the mounting frame 41 are fixedly installed at the left and right positions of the rear upper end of the base 1, the middle part of the upper end of the mounting frame 41 is slidably connected with a moving rod 42 that passes through the top of the mounting frame 41, and the top of the outer wall of the moving rod 42 is movably sleeved with a return spring 43, the lower end of the return spring 43 is fixedly connected to the middle part of the upper end of the mounting frame 41, the upper end of the return spring 43 is fixedly connected to the top of the outer wall of the moving rod 42, the upper left part of the mounting frame 41 is rotatably connected with a punching rod 44, and the middle part of the lower end of the punching rod 44 overlaps the upper end of the moving rod 42.

[0037] By rotating the punch rod 44 downward, the punch rod 44 applies pressure to the moving rod 42, so that the moving rod 42 compresses the return spring 43 and moves downward, wherein the elastic potential energy of the return spring 43 can drive the moving rod 42 to return when the punch rod 44 moves upward.

[0038] like Figure 2 and Figure 5 As shown, movable grooves 45 are provided on the left and right parts of the inner wall of the mounting frame 41, a movable plate 46 is fixedly installed on the lower end of the movable rod 42, and limit blocks 47 are fixedly installed on the left and right sides of the movable plate 46, and the ends of the two limit blocks 47 that are away from each other are slidably connected to the inner walls of the two movable grooves 45, and a fixed shaft 48 is fixedly installed on the lower end of the movable plate 46.

[0039] Through the moving action of the moving rod 42 , the moving plate 46 slides in the two moving grooves 45 through the two limit blocks 47 and moves up and down, and the moving plate 46 drives the fixed shaft 48 to move up and down.

[0040] like Figure 6 As shown, the outer wall of the fixed shaft 48 is slidably connected to a plurality of sliding sleeves 49 arranged in a linear manner, a punching drill 410 is fixedly installed on the bottom of the outer walls of the plurality of sliding sleeves 49, a plug hole 411 is opened on the top of the outer wall of the fixed shaft 48, the top of the outer wall of the plurality of sliding sleeves 49 is slidably connected to an adjusting rod 412 that passes through the top of the outer wall of the plurality of sliding sleeves 49, the lower ends of the plurality of adjusting rods 412 are plugged into the inner walls of the plurality of plug holes 411, the top of the outer walls of the plurality of adjusting rods 412 are movably sleeved with a spring 413, the lower ends of the plurality of springs 413 are fixedly connected to the top of the outer walls of the plurality of sliding sleeves 49, and the upper ends of the plurality of springs 413 are fixedly connected to the top of the outer walls of the plurality of adjusting rods 412.

[0041] Through the movement of the fixed shaft 48, the fixed shaft 48 drives the plurality of sliding sleeves 49 and the punching drill 410 to move, so that the punching drill 410 punches holes in the account book. At the same time, before the punching work, the plurality of adjusting rods 412 can be pulled according to the actual situation, so that the corresponding springs 413 are compressed and accumulate elastic potential energy, so that the plurality of adjusting rods 412 and the corresponding plug holes 411 are disconnected from the plug-in relationship, and then the corresponding sliding sleeves 49 are slid, and after the adjusting rods 412 are released, the elastic potential energy of the springs 413 can insert the plurality of adjusting rods 412 into the new plug holes 411.

[0042] The working principle of the utility model is as follows: the operator pushes the account book until the side of the account book that needs to be punched fits with the front side of the baffle 24, pulls the two positioning plates 27, and the four limit springs 29 are squeezed at the same time to accumulate elastic potential energy, and the six fixing columns 28 are disconnected from the corresponding fixing holes 25. According to the change of the scale line, the measuring plate 21 is pushed, and the measuring plate 21 drives the baffle 24 to move to the appropriate position, loosens the two positioning plates 27, and the four limit springs 29 release the elastic potential energy to connect the six fixing columns 28 with the new fixing holes 25, thereby fixing the measuring plate 21 and determining the position where the account book needs to be punched.

[0043] Then, the two adjusting screws 32 are rotated, and the two adjusting screws 32 are threadedly connected with the two mounting plates 31 to drive the two limiting plates 33 to move closer to each other to fix and clamp the account book.

[0044] The operator rotates the punching rod 44 downward, and the punching rod 44 applies downward pressure to the upper end of the moving rod 42. The moving rod 42 drives the moving plate 46 to move and squeezes the reset spring 43. The moving plate 46 moves downward through the cooperation of two limit blocks 47 and two moving grooves 45. The moving plate 46 drives several punching drills 410 to punch holes in the account book. The operator releases the punching rod 44, and the elastic restoring force of the reset spring 43 drives the moving rod 42 and the moving plate 46 to reset, which is convenient for subsequent punching work.

[0045] When the punching spacing needs to be adjusted according to actual conditions, several adjusting rods 412 are pulled at the same time, the corresponding springs 413 are subjected to tensile force and the adjusting rods 412 are separated from the plug-in relationship with the corresponding sockets 411, and several sliding sleeves 49 are slid to the appropriate position. At the same time, the corresponding adjusting rods 412 are loosened, and the elastic potential energy of several springs 413 makes several adjusting rods 412 plug into the new sockets 411, so that the distance between the punching drill bits 410 can be adjusted, so that when punching holes in the account book, it can be adjusted according to the actual situation to ensure the subsequent binding work of the account book.
