Description

Technical Field

[0001] The utility model relates to the technical field of punching devices, in particular to a puncher. Background Art

[0002] Traditional punching pliers on the market are all pliers-style, that is, the two pliers handles are pivoted together, and the two pliers are manually held to press and open the two pliers to apply punching pressure to the object (such as belts, paper, metal plates, etc.) to complete the punching action.

[0003] Due to the limitations of the movement size (specifically the distance from the punching head of the traditional pliers-type punching tool to the hinge point of the two pliers bodies, and the maximum distance that the punching head of the traditional pliers-type punching tool can open), traditional punching pliers have certain requirements and restrictions on the thickness and width of the punched object. For example, it is inconvenient to punch holes in thicker objects, and it is impossible to punch a hole in the center of a wider object, which limits the usage scenarios. Utility Model Content

[0004] The purpose of the utility model is to provide a hole punch, which solves the technical problem of limited usage scenarios of the hole punching devices in the prior art.

[0005] The present application discloses a hole puncher, comprising:

[0008] an elastic member, mounted on the guide post;

[0009] a piston movably mounted on the guide post, with an end of the piston extending out of the open end of the outer cylinder;

[0010] a cutter head seat, mounted on the end of the elastic member, and the cutter head seat is located inside the piston;

[0011] A tightening unit is mounted on the inner wall of the outer cylinder, and a tightening end of the tightening unit cooperates with the bottom of any circle of the elastic member to tighten the elastic member;

[0012] a trigger unit, mounted on the outer wall of the piston;

[0013] After the piston moves toward the tightening unit, the trigger unit contacts and cooperates with the tightening unit and pushes the tightening unit to rotate so that the elastic member is released.

[0014] The present application is provided with a tightening unit and a trigger unit. The tightening of the elastic part is completed by the tightening unit, and then the trigger unit contacts the tightening unit to rotate the tightening unit, thereby completing the release of the elastic part and pushing the cutter head seat to punch straight to complete the subsequent punching operation.

Those skilled in the art will understand the specific meanings of these terms in this utility model based on specific circumstances.

[0049] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0050] Example:

[0051] like Figure 1-7As shown, the present application discloses a puncher, which changes the style of the traditional pliers-type punching tool and is set as a straight-cylinder puncher for realizing grip-type punching, breaking away from the constraints of the traditional punching pliers structure, and can punch holes in thicker objects, can achieve a hole in the center of a wider punched object, and can perform arbitrary punching.

[0052] like Figure 1 、 3 As shown, the specific structure of this application is as follows, including:

[0053] The outer cylinder 1 is a hollow cylinder, and one end of the outer cylinder 1 is an open end;

[0054] The guide column 2 is installed inside the outer cylinder 1. The guide column 2 is installed inside the outer cylinder 1 and can be connected and fixed through the base inside the outer cylinder 1. The extension direction of the guide column 2 is the axial direction of the outer cylinder 1.

[0055] The elastic member 3 is mounted on the guide column 2 and serves as the power source of the entire system, and is used to drive the subsequent movement of the cutter head seat, complete the downward punching of the cutter head, and realize the punching operation;

[0056] The piston 4 is movably mounted on the guide column 2, and the end of the piston 4 extends out of the open end of the outer tube 1; the piston 4 can freely move up and down along the guide column 2, and its main purpose is to provide a trigger point so that the elastic member 3 can be released, thereby completing the punching operation. Specifically, in the normal placement state, part of the piston 4 is located outside the open end of the outer tube 1, and the remaining part is located inside the outer tube 1; the specific installation method of the piston 4 can be an existing one or the following installation method. The piston 4 in the present application is provided with an outer edge at one end located inside the outer tube 1. The inner diameter of the opening end of the outer tube 1 is smaller than the outer diameter of the outer edge, so that the piston 4 will not separate from the outer tube 1; another elastic member can also be installed inside the outer tube 1, and the end of the elastic member is connected to the piston 4, so as to prevent the piston 4 from separating; a rubber block can also be installed at the opening of the outer tube 1, and the other end of the piston is still provided with an outer edge, and a through hole for the piston to pass through is opened on the rubber block, but the through hole prevents the outer edge from passing through, so that the stability of the movement of the piston 4 can be ensured and the piston 4 can be prevented from separating from the outer tube; the specific installation method of the piston 4 can also be a combination of the above several situations;

[0057] The cutter head seat 5 is mounted on the end of the elastic member 3, and the cutter head seat 5 is located inside the piston 4. After the elastic member 3 is inserted into the piston 4, it is connected with the cutter head seat 5, that is, it pushes the cutter head seat 5 to move. In subsequent work, a cutter head is installed at the end of the cutter head seat 5 to facilitate the punching operation during stamping.

[0058] In order to achieve the purpose of releasing the punching in this application, a trigger switch is provided inside the outer cylinder 1. After the trigger switch is triggered, the elastic member 3 can be released, pushing the cutter head seat 5 downward, that is, realizing the punching of the cutter head and completing the punching operation. Specifically, the trigger switch is divided into two parts, as shown below:

[0059] The tightening unit 6 is mounted on the inner wall of the outer tube 1, and the tightening end of the tightening unit 6 cooperates with the bottom of any loop of the elastic member 3 to tighten the elastic member 3. The purpose of the tightening unit 6 is to complete the tightening of the loop of the elastic member 3. When the elastic member 3 is squeezed, the loop of the elastic member 3 tightens and, after passing the tightening unit 6, is constrained by the tightening unit 6 and cannot move downward, that is, the elastic member 3 can only be tightened continuously;

[0060] The trigger unit 7 is installed on the outer wall of the piston 4; the trigger unit 7 moves synchronously with the piston 4. When the outer tube 1 is tightened by human power, the piston 4 moves upward, thereby driving the trigger unit 7 to move upward, cooperate with the tightening unit 6 and open the tightening unit; specifically, after the piston 4 moves toward the tightening unit 6, the trigger unit 7 contacts and cooperates with the tightening unit 6 and pushes the tightening unit 6 to rotate so that the elastic member is released.

[0061] There are many options for the elastic member in the present application, as long as it has an elastic function. The preferred option is a spring. The specific assembly form is that the spring is mounted on the guide column 2.

[0062] The trigger unit 7 and the tightening unit 6 in the present application can be in various forms. The tightening unit 6 can be an electric unit. When the trigger unit 7 triggers the switch of the tightening unit 6, the tightening unit 6 opens, thereby completing the release of the elastic member 3. Alternatively, the structure can be as follows:

[0063] like Figure 4 、 5 As shown, the tightening unit 6 includes:

[0064] A tightening shaft 601 is mounted on the inner wall of the outer cylinder 1 and serves as a rotating support.

[0065] A tightening block 602 is movably mounted on the tightening shaft 601, and a torsion spring 603 is installed between the tightening block 602 and the tightening shaft 601; the end of the tightening block 602 is engaged with one of the rings of the elastic member 3, and the tightening block 602 rotates around the tightening shaft 601;

[0066] The trigger unit 7 is a support member 701 , and the support member extends toward the tightening block 602 .

[0067] In order to ensure the tightening work of the tightening block 602 and the triggering work of the support member 701, the present application further explains the structures of the tightening block 602 and the support member 701:

[0068] The tightening block 602 includes:

[0069] The connecting section 604 is mounted on the tightening shaft 601;

[0070] The hook section 605 is mounted on the end of the connecting section 604 facing the guide column 2. The hook section 605 engages with the bottom of one of the loops of the elastic member 3. The outer edge of the hook section 605 is arc-shaped. When the tightening block 602 is pushed by the support member 701, it can be separated from the elastic member 3, and the elastic member 3 can be released.

[0071] The support member 701 is L-shaped. Preferably, the vertical section of the support member 701 cooperates with the end of the connecting section 604 away from the guide column 2. Specifically, the support member 701 pushes the tightening block 602 to rotate around the tightening shaft 601 to complete the release of the elastic member.

[0072] In order to further ensure the stability of the guide column 2 installed inside the outer cylinder 1, the present application is equipped with a base 8 inside the outer cylinder 1. The base 8 is installed on the cylinder body of the outer cylinder 1, and the guide column 2 is installed on the base 8, which can ensure the stability of the guide column 2.

[0073] like Figure 7 As shown, in order to leave a cavity for placing objects later, the present application is also provided with an end cover 101, which is installed at the end of the outer tube 1 away from the open end, and a gap is left between the end cover 101 and the base 8 to serve as an assembly cavity 13; the end cover 101 in the present application serves as an assembly part, wherein the open end 1 is located at the head end of the outer tube 1, and the end cover 101 is installed at the tail end of the outer tube 1, and the assembly cavity 13 serves as a storage space.

[0074] In order to be suitable for punching more specifications, the present application accommodates replacement cutter heads, and the replacement cutter heads are placed through the assembly cavity. At the same time, the replacement cutter heads 12 are of various sizes. When not in use, they are stored inside the assembly cavity 13. When used later, you only need to take out the corresponding replacement cutter head and install it on the cutter head seat 5.

[0075] In order to prevent the working surface from being damaged when the present application is in use, the present application is also provided with a gasket 11. When not in use, the gasket 11 is stored in the assembly cavity 13. When in use, the gasket 11 is placed on the outside of the outer cylinder 1 and corresponds to the cutter head seat 1, so as to play a supporting role and avoid damage to the table top.

[0076] When the gasket 11 is actually assembled, the gasket 11 is adsorbed to the inner side of the end cover 101 by magnetic attraction; or the gasket 11 is snapped onto the inner side of the end cover 101, that is, the gasket 11 can be adsorbed by magnetic attraction, or a hook can be provided on the inner side of the end cover, and then the gasket 11 is placed, which is convenient for taking and placing, and will not affect the taking and placing of other replacement blades 12.

[0077] In order to further ensure the stability of piston movement, such as Figure 2 As shown, the present application provides a protective sleeve 9 at the open end of the outer cylinder 1 , and the protective sleeve 9 has a through hole 10 for the piston 4 to pass through, so as to ensure the stability of the up and down movement of the piston 4 .

[0078] Further explanation for this application:

[0079] The present application changes the style of the traditional pliers-type punching pliers and is set as a straight-cylinder punch. When in use, a gasket can be placed on the back of the object to be punched to prevent the punch from accidentally damaging work surfaces such as the desktop and the ground; when not in use, the gasket can be stored in the assembly cavity 13 of the outer tube 1 of the present application. Specifically, the gasket can be magnetically adsorbed or clamped into the assembly cavity 13 through other simple structures.

[0080] An assembly cavity 13 is provided at the tail end of the present application as a storage space. The storage space has a structure for storing and storing replacement blade heads. The sizes of the replacement blade heads are different. The blade head of the hole punch is a detachable structure. When holes of different sizes need to be punched, a blade head of the corresponding size can be used.

[0081] The present application can adopt a one-handed grip and pressing method, completely getting rid of the constraints of the traditional punching pliers structure, being able to punch holes in thicker objects, being able to punch holes in the center of wider objects, and being able to perform arbitrary punching; specifically, the present application can realize the release of the elastic part 3 through the movement of the piston 4, that is, after the piston 4 is immersed in the interior of the outer tube 1, the support part 701 pushes the tightening block 602 to rotate, thereby realizing the release of the elastic part 3, and the cutter head seat 5 rushes downward under the drive of the elastic part to complete the punching.
