[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See also Figure 1-3 The utility model provides an economical hole punch, including a hole punch arranged above a fixed base 101, the hole punch consisting of a fixed base 102 and a hole punch insert 103, and further comprising a mounting rod 2 fixed to the upper end of the fixed base 101, the lower end of the fixed base 102 being fixed to one end of the mounting rod 2, and an installation component for auxiliary installation being provided between the fixed base 102 and the hole punch insert 103;

[0020] The mounting assembly includes a tapered hole 301 formed on the fixing seat 102, a tapered rod 302 fixed to the lower end of the hole-turning punch insert 103, the tapered hole 301 and the tapered rod 302 being matched with each other, a positioning assembly for assisting positioning during the installation process is provided between the fixing seat 102 and the hole-turning punch insert 103, and a pushing assembly for assisting in separating the hole-turning punch insert 103 from the fixing seat 102 is provided on the mounting rod 2;

[0021] It should be noted here that when the hole-turning punch is in use, the detachable installation between the fixing seat 102 and the hole-turning punch insert 103 facilitates the replacement of the damaged hole-turning punch insert 103, thereby achieving the purpose of economy. During the installation and disassembly process of the hole-turning punch insert 103, the mutual cooperation between the installation component and the pushing component can not only ensure the stability of the hole-turning punch insert 103 after installation, but also assist in the disassembly and separation of the hole-turning punch insert 103 after use, thereby facilitating the operation and use of the economical hole-turning punch.

[0022] The tapered hole 301 and the tapered rod 302 are arranged in a Morse taper;

[0023] It should be noted here that: the hole-turning punch insert 103 is pushed toward the fixed seat 102. During the pushing process, the tapered rod 302 and the tapered hole 301 are offset against each other. Since the tapered hole 301 and the tapered rod 302 are set in a Morse taper, the characteristic of the very small taper is utilized, and through the principle of friction, the pushed hole-turning punch insert 103 is installed and fixed on the fixed seat 102.

[0024] The positioning assembly includes a positioning hole 401 formed on the fixing seat 102, and a positioning pin 402 matching the positioning hole 401 is fixed to the lower end of the punch insert 103;

[0025] It should be noted here that when the hole-turning punch is in use, the hole-turning punch insert 103 is pushed toward the fixing seat 102. During the pushing process, the tapered rod 302 and the tapered hole 301 are offset against each other through the positioning and guiding effects of the multiple sets of positioning holes 401 and the positioning pins 402.

[0026] There are multiple groups of positioning holes 401 and positioning pins 402, and the multiple groups of positioning holes 401 and positioning pins 402 are arranged in a circular array;

[0027] It should be noted here that the positioning effect is ensured by using multiple groups of positioning holes 401 and positioning pins 402.

[0028] The pushing assembly includes a push rod 501 slidably connected to the positioning hole 401 for pushing against the end of the positioning pin 402 after positioning. A push ring 502 is sleeved on the outer side of the mounting rod 2. One end of each group of push rods 501 is fixed to the push ring 502.

[0029] It should be noted here that: when the hole-turning punch insert 103 needs to be disassembled and separated, the pushing ring 502 is pushed toward the lower end of the fixed seat 102. During the pushing process, each group of push rods 501 slides on each group of positioning holes 401 and resists against the positioning pins 402. Through the resisting action, a thrust is generated on the positioning pins 402 and each group of hole-turning punch inserts 103, assisting the disassembly and separation operation between the hole-turning punch insert 103 and the fixed seat 102.

[0030] The outer side of the mounting rod 2 is provided with a spring 6, and the two ends of the spring 6 are fixed to the push ring 502 and the fixed base 101 respectively;

[0031] It should be noted that during the movement of the push ring 502 , the spring 6 is deformed by force to generate elastic force, and the elastic force of the spring 6 facilitates the reset of the push ring 502 after the movement.

[0032] Working Principle: When the hole-turning punch is in use, the hole-turning punch insert 103 is pushed toward the fixed seat 102. During the pushing process, the tapered rod 302 and the tapered hole 301 are offset against each other through the positioning and guiding effect of the multiple sets of positioning holes 401 and the positioning pins 402. Since the tapered hole 301 and the tapered rod 302 are arranged in a Morse taper, the characteristic of the small taper is utilized. Through the principle of friction, the pushed hole-turning punch insert 103 is installed and fixed on the fixed seat 102, thus completing the installation of the hole-turning punch insert 103.

[0033] After the hole punch insert 103 is installed, as the hole punch performs the hole-turning operation, the front end of the hole punch insert 103 is pushed against the fixing seat 102 by force. During the squeezing process, the tapered hole 301 and the tapered rod 302 are further fitted together, thereby ensuring the installation effect of the hole punch insert 103.

[0034] When the hole-turning punch insert 103 needs to be disassembled and separated, the pushing ring 502 is pushed toward the lower end of the fixed seat 102. During the pushing process, each group of push rods 501 slides on each group of positioning holes 401 and abuts against the positioning pins 402. Through the abutting effect, a thrust is generated on the positioning pins 402 and each group of hole-turning punch inserts 103, assisting the disassembly and separation operation between the hole-turning punch insert 103 and the fixed seat 102.

[0035] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
