To ensure that ivory products do not flow into domestic and foreign illegal markets, customs inspection departments or relevant regulatory departments usually need to have ivory testing tools and methods. Currently, commonly used ivory testing methods include molecular biology methods, which obtain results by monitoring powdered samples. The sampling process for hard samples usually involves cutting a sample and then crushing it to obtain the required powder sample for testing. The cutting process is wasteful due to powder splashing, and the hard sample is significantly damaged after cutting, causing considerable damage to the sample. Utility Model Content

[0003] The purpose of this invention is to provide a hard sample sampling tool to solve the technical problem that current commonly used ivory testing methods, including molecular biology methods, obtain results by monitoring powdered samples. The hard sample sampling process usually involves cutting a sample and then crushing it to obtain the required powder sample for testing. The cutting process is wasteful due to powder splashing, and the hard sample is greatly damaged after cutting, causing significant damage to the sample.

[0004] To achieve the above objectives, the specific technical solution of this utility model for a hard sample taking tool is as follows: A rigid sample collection tool includes a body; a motor is installed inside the body; a transmission device is connected to the motor shaft; a clamping device is installed on the outer side of one end of the transmission device; a grinding head is installed on one side of the clamping device; cooling inlets are symmetrically arranged on both sides of the body near the clamping device; cooling outlets are symmetrically arranged on both sides of the body away from the clamping device; a mounting buckle is installed on the body near the clamping device; a soft rubber corrugated sleeve is installed on the mounting buckle extending outwards from the clamping device and the grinding head; a spring is connected between the mounting buckle and the end of the soft rubber corrugated sleeve away from the mounting buckle; a connecting compartment is installed below the mounting buckle; a filter box is slidably installed in the connecting compartment; the upper side of the filter box communicates with the space inside the soft rubber corrugated sleeve through the mounting buckle; a fan is installed on one side of the connecting compartment; a through hole is provided on one side of the filter box opposite the fan; a filter screen is installed in the filter box near the through hole; and an air outlet is provided in the connecting compartment opposite the fan.

[0005] Furthermore, the grinding head can be selected and installed in different specifications and styles according to usage requirements.

[0006] Furthermore, the filter screen is set at an angle.

[0007] Furthermore, the air outlet of the connecting compartment is connected to a ventilation duct that extends to the opposite cooling inlet positions on both sides of the machine body.

[0008] This utility model provides a hard sample sampling tool with the following advantages: A soft corrugated sleeve is placed against the outside of the sample grinding area. A motor and transmission device within the main body drive the clamping device and grinding head to rotate, grinding the hard sample. Simultaneously, a fan is activated, creating negative pressure through a through-hole inside the filter box and soft corrugated sleeve. This draws the powder sample falling off the grinding head into the filter box, where it is filtered and stored for subsequent testing. The sampling process is convenient, only surface sampling is performed on hard samples, minimizing damage. Furthermore, most of the powder sample generated during grinding is collected in the filter box by the negative pressure generated by the fan. This design avoids sample waste, reduces the amount of powder samples splashed into the air and causing environmental pollution, and also reduces the amount of hard samples to be taken, minimizing damage to hard samples. By connecting the air outlet of the connecting chamber to the cooling inlets on both sides of the machine body, when the fan is started, negative pressure is generated inside the filter box and the soft rubber corrugated sleeve to draw in sample powder. The exhaust air enters the ventilation duct through the air outlet, and then enters the relatively high-temperature structures inside the machine body, such as the motor, through the cooling inlets. The flowing air cools the internal components, and then the airflow carrying the heat is discharged through the cooling outlet, effectively cooling the internal components and increasing the stability of the device during use.

[0010] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of a rigid sample taking tool according to this utility model.

[0011] like Figure 1-4 As shown, this utility model discloses a hard sample taking tool, including a body 1; a motor 2 is installed inside the body 1; a transmission device 3 is connected to the shaft of the motor 2; a clamping device 4 is installed on the outer side of one end of the transmission device 3; a grinding head 5 is installed on one side of the clamping device 4; cooling inlets 6 are symmetrically arranged on both sides of the body 1 near the clamping device 4; cooling outlets 7 are symmetrically arranged on both sides of the body 1 away from the clamping device 4; mounting buckles 8 are installed on the body 1 near the clamping device 4; the mounting buckles 8 extend outwards from the clamping device 4 and the grinding head 5. A soft rubber corrugated sleeve 9 is provided; a spring 10 is provided between the mounting buckle 8 and the end of the soft rubber corrugated sleeve 9 away from the mounting buckle 8; a connecting compartment 11 is provided on the lower side of the mounting buckle 8; a filter box 12 is slidably provided in the connecting compartment 11; the upper side of the filter box 12 is connected to the space inside the soft rubber corrugated sleeve through the mounting buckle 8; a fan 13 is provided on one side of the connecting compartment 11; a through hole 14 is provided on one side of the filter box 12 opposite to the fan 13; a filter screen 15 is provided in the filter box 12 near the through hole 14; an air outlet 16 is provided in the connecting compartment 11 opposite to the fan 13.

[0012] Combination Figure 1-3 As shown, during use, the soft rubber corrugated sleeve 9 is placed against the outside of the sample grinding position. The spring 10 pushes the soft rubber corrugated sleeve 9 to adhere to the hard sample. Then, the motor 2 is started. The motor 2 drives the clamping device 4 and the grinding head 5 to rotate through the transmission device 3 to grind the hard sample. At the same time, the fan 13 is started. The fan 13 creates negative pressure in the filter box 12 and the soft rubber corrugated sleeve 9 through the through hole 14, sucking the powder sample that falls off the grinding head 5 into the filter box 12. After being filtered by the filter screen 15, it is stored in the filter box 12 for subsequent use of the powder sample for testing. The sampling process is relatively convenient. Only the surface of the hard sample is sampled, resulting in less damage. Moreover, most of the powder sample generated during the grinding process is collected in the filter box 12 by the negative pressure generated by the fan 13, avoiding sample waste, reducing the amount of powder sample splashed into the air and causing environmental pollution, and also reducing the amount of hard sample to be sampled, thus reducing the damage to the hard sample.

[0013] The grinding head 5 can be installed in different specifications and styles according to the usage requirements. Depending on the different shapes or specifications of the sample, it can be selected such as disc type, cylindrical type, conical type, etc., to ensure that the grinding head 5 can be rotated by the clamping device 4 to grind and rub the sample powder off the hard sample. At the same time, the appropriate specification can be selected from different specifications and styles of grinding head 5 to reduce damage to hard samples.

[0014] The filter screen 15 is set at an angle. When the fan 13 generates negative pressure in the filter box 12 and the soft rubber corrugated sleeve 9, the sample powder ground by the grinding head 5 is sucked into the filter box 12. The sample powder is then filtered into the filter box 12 by the filter screen 15. The sample powder filtered by the angled filter screen 15 falls into the filter box 12 by gravity, preventing the sample powder from clogging the filter screen 15, reducing the negative pressure in the filter box 12 and the soft rubber corrugated sleeve 9, and facilitating the collection of sample powder.

[0015] Combination Figure 4 As shown, the air outlet 16 of the connecting chamber 11 is connected to a ventilation duct 17 extending to the opposite cooling inlets 6 on both sides of the body 1. By connecting the air outlet 16 of the connecting chamber 11 to the opposite cooling inlets 6 on both sides of the body 1, when the fan 13 is started to generate negative pressure to suck up sample powder in the filter box 12 and the soft rubber corrugated sleeve 9, the exhaust air enters the ventilation duct 17 through the air outlet 16, and then enters the relatively high temperature structure such as the motor 2 inside the body 1 through the cooling inlet 6. The flowing air cools the internal structure of the body 1, and then the flowing air carrying heat is discharged through the cooling outlet 7, effectively cooling the inside of the body 1 and increasing the stability of the device during use.
