If it is described as first, second, it is only used for the purpose of distinguishing technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated or the sequence of technical features indicated.

[0021] In the description of the present application, unless otherwise explicitly limited, the words such as setting, installing, connecting, etc. should be broadly understood, and the person skilled in the art can reasonably determine the specific meaning of the above words in the present application in combination with the specific content of the technical scheme.

[0022] Please refer to Figure 1 , now the sample punching tool provided by the embodiments of the present application will be described.

[0023] As shown in Figure 1 , the sample punching tool of the present application comprises a guide rod 100 and a sample punch 200, one end of the guide rod 100 is connected with a self-tightening clamp, the guide rod 100 is provided with a mounting hole arranged along the axial direction thereof, the sample punch 200 is inserted and mounted in the mounting hole and locked by the self-tightening clamp, a sleeve 400 is sleeved on the outer side of the guide rod 100, a handle 500 extending outward is connected to the outer side of the sleeve 400, the other end of the guide rod 100 is connected with an impact plate 600, the area of the impact plate 600 is greater than the cross-sectional area of the guide rod 100.

[0024] The guide rod 100 is a hollow structure, and the sample punch 200 is inserted into the self-tightening clamp of the guide rod 100, so as to ensure that the length directions of the sample punch 200 and the guide rod 100 are the same, and the safety problem caused by the inclination of the punch during the operation of the sample punch 200 is avoided, the unsafe behavior caused by the sample punch 200 during the operation of the sample punch 200 is solved, the probability of accidental injury of the worker is greatly reduced, and the worker can conveniently hold the handle 500 to operate the sample punch 200.

[0025] For example, the handle 500 has two, and the two handles 500 are arranged at the same horizontal height, which is convenient for the worker to hold. When a larger workpiece is operated by the sample punch 200, two workers are usually needed to operate, one of whom can hold two handles 500 with both hands to fix the sample punch tooling, and the other can swing a hammer to hit. The two handles 500 can make the holding and positioning more stable and not easy to shake and hit the hand.

[0026] For example, the self-tightening clamp is a self-locking drill chuck capable of adjusting the tightness of the chuck, which is convenient for clamping and disassembling the sample punch 200. The sample punch 200 is usually cylindrical, and the self-locking drill chuck is convenient for clamping the cylindrical sample punch 200. Moreover, the self-locking drill chuck is convenient to disassemble, so that the sample punch tooling can be used for a longer period of time after the damaged sample punch 200 is replaced.

[0027] For example, the self-locking drill chuck is provided with a three-jaw chuck capable of clamping a cylinder, and the tightness of the self-locking drill chuck is adjusted by rotating the chuck wrench. The three-jaw chuck is convenient for clamping the cylindrical sample punch 200, and the tightness is adjusted by rotating the chuck wrench, so that the clamping is more stable and the sample punch 200 is not easy to fall off when it is subjected to impact. When disassembled, the sample punch 200 can be easily replaced by loosening the chuck wrench.

[0028] For example, the guide rod 100 is a stainless steel pipe with a diameter of 20 mm. The main function of the guide rod 100 is to ensure that the sample punch 200 maintains a stable movement trajectory during the impact process. The guide rod 100 can significantly reduce the shaking and deviation of the sample punch 200 during the impact process, thereby improving the accuracy of the impact. The material of the guide rod 100 should have certain hardness, wear resistance and lightness to ensure its service life, stability and portability, so a stainless steel pipe is used.

[0029] For example, the impact plate 600 is a circular plate with a diameter of 40 mm, which ensures that the area of the impact plate 600 is significantly larger than the cross-sectional area of the guide rod 100, so that the sample punch 200 can be more stably hit on the impact plate 600, and the operator's hand is not easy to be hit.

[0030] For example, the sleeve 400 is fixedly connected to the guide rod 100. When the punch 200 is in operation, the handle 500 on the outside of the sleeve 400 needs to be held. The fixed connection between the sleeve 400 and the guide rod 100 can ensure that it will not shift and cause danger when transmitting impact force.

[0031] The advantages of implementing the punching fixture provided by this utility model compared with the prior art are as follows:

[0032] This invention features a guide rod 100 with a self-tightening clamp at its end to hold the punch 200, facilitating easy replacement of the punch 200. After repeated use and wear, the punch 200 can be easily removed and replaced with a new one using the self-tightening clamp, allowing for continued use. This gives the punch fixture high wear resistance and a long service life. The punch fixture transmits impact force through the guide rod 100, providing good stability. A sleeve 400 is fitted onto the outside of the guide rod 100, and an outwardly extending handle 500 is connected to the outside of the sleeve 400, facilitating gripping by the operator and adapting to various working angles. The punch 200 can be punched vertically downwards, horizontally at the side of the workpiece, or at tilted or upward angles. The 00 operation mode can meet the needs of different working environments on site. The handle 500 makes it easier to exert force and operate. By holding the handle 500 and using the self-tightening clamp to hold the punch 200, the risk of hand injury caused by slight deviations when directly holding the side of the punch 200 in the traditional method is avoided. The other end of the guide rod 100 is connected to the impact plate 600. Striking the impact plate 600 transmits the impact force, causing the punch 200 to make a dent on the workpiece for subsequent operations. The area of ​​the impact plate 600 is larger than the cross-sectional area of ​​the guide rod 100, which increases the area that can be struck when the punch 200 is in operation, improves the fault tolerance. Even if there is a slight deviation, at least the punch will hit the impact plate 600 to transmit the impact force, avoiding hand injury and improving safety. Moreover, the operation is simple.

[0033] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
