Description

Technical Field

[0001] This utility model relates to the field of wildlife rescue technology, specifically a tick-catching device for pangolins. Background Technology

[0002] Pangolins are endangered protected animals, and their wild populations are rapidly declining. All eight currently identified pangolin species are listed in Appendix I of the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) and are classified as critically endangered, endangered, or vulnerable on the IUCN Red List of Threatened Species. The Chinese pangolin, in particular, is listed as critically endangered by the IUCN and was designated a Class I protected animal in China in 2020. Therefore, the importance of rescuing wild pangolins is self-evident.

[0003] The inventors discovered in practice that pangolins rescued from the wild often have a large number of ticks attached to their scales. Ticks, as ectoparasites, can cause anemia and even death in pangolins. Juvenile pangolins infested with ticks may suffer from malnutrition, affecting their growth and development. Furthermore, tick bites can cause skin inflammation, ulcers, and secondary bacterial infections in pangolins. Ticks can also act as vectors for disease transmission. Therefore, it is necessary to remove ticks from pangolins during rescue operations. However, pangolins' easily startled nature makes restraint difficult, and their scales provide hiding places for ticks. Removing ticks requires opening the scales to find them, making tick removal inconvenient and posing a risk of scratches from the scales. Therefore, there is an urgent need to design a device for tick capture based on the unique scale structure of pangolins, thus facilitating tick removal for rescuers. Utility Model Content

[0004] To address the shortcomings of the prior art, this utility model provides a tick-catching device for pangolins. Through the ingenious design of a rocker arm, telescopic tube, and mechanical claw, it allows for the manipulation of pangolin scales and the catching of ticks with a single hand. The device is simple in structure, easy to carry, convenient to use, and avoids the risk of scratches.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a tick-catching device for pangolins, comprising a handheld shell, a screw, a telescopic tube, a drive motor, a mechanical claw, an electromagnet, a battery, and a rocker arm. A sleeve extends forward from the top of the handheld shell. A screw is coaxially mounted inside the sleeve. A cylindrical section is provided at the rear end of the screw and rotatably connected to the inner cavity of the top of the handheld shell via a bearing. The telescopic tube is slidably inserted inside the sleeve. A nut is provided at the rear end of the telescopic tube and screwed into the screw. A guide protrusion is provided axially on the outer wall of the telescopic tube, forming a sliding pair with a pre-made groove on the inner wall of the sleeve. The drive motor is fixedly installed in the inner cavity of the top of the handheld shell and connected to the drive screw via a gear set. The mechanical claw includes a mounting base, a T-shaped control component, two gripping arms, and two transmission connecting rods. The mounting base is coaxially mounted at the front end of the telescopic tube. The longitudinal support arm of the T-shaped control component extends into the telescopic tube through the pre-drilled center hole of the mounting base and is fixed with a magnetic suction part. A compression spring is set between the transverse support arm of the T-shaped control component and the mounting base. The ends of the two clamping arms are respectively hinged to the two sides of the mounting base. The top ends of the two clamping arms are integrally set with clamps. The two ends of the two transmission connecting rods are respectively hinged to the middle position of the two clamping arms and the end of the transverse support arm of the T-shaped control component. The electromagnet is installed and fixed inside the telescopic tube and is configured to cooperate with the magnetic suction part. The battery is installed at the bottom of the handheld shell to power the drive motor and the electromagnet. A three-position switch and a push-button switch are set at the middle position of the front side of the handheld shell. The three-position switch controls the forward rotation, reverse rotation and stop operation of the drive motor. The push-button switch controls the start and stop of the electromagnet. The rocker is set along the front-back direction and is mounted on the top of the handheld shell through a torsion hinge.

[0006] Furthermore, the sleeve has an integrally formed adapter groove at the bottom front end and a detachable collection tube is installed thereon, and the collection tube is connected to the sleeve.

[0007] Furthermore, the drive motor is a geared motor or the gear set is a reduction gear set.

[0008] Furthermore, the mounting base and the telescopic tube are installed using a detachable connection method.

[0009] Furthermore, the battery is a removable rechargeable battery.

[0010] Compared with the prior art, the advantages of this utility model are as follows: This utility model has a rocker plate at the top, which can be turned over by pressing with the thumb using the lever principle. After the tick is found, the extension of the telescopic tube can be adjusted by controlling the drive motor to drive the screw through a three-position switch. The mechanical claw can be closed by controlling the electromagnet through a button switch, which facilitates the capture of ticks hidden under the tick and avoids the risk of scratching. After the tick is captured, the mechanical claw is retracted into the sleeve, and the electromagnet is disconnected to reset the mechanical claw and open it. The tick can fall directly into the collection tube. As the mechanical claw extends again, the telescopic tube can close the collection tube to prevent the tick from escaping. Moreover, the operation of turning over the tick and capturing the tick can be performed with one hand, so as to free up the other hand for restraint or disinfection work. The structure is simple and easy to carry, reducing the number of hands required for operation and improving work efficiency. Attached Figure Description

[0014] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.

[0015] like Figures 1-2 As shown, a tick-catching device for pangolins includes a handheld shell 1, a screw 2, a telescopic tube 3, a drive motor 4, a mechanical claw 5, an electromagnet 6, a battery 7, and a rocker 8.

[0016] The top of the handheld housing 1 extends forward to form a sleeve 1-1 for mounting the telescopic mechanism. A screw 2 is coaxially mounted inside the sleeve 1-1. The rear end of the screw 2 has a cylindrical section 2-1, which is rotatably connected to the inner cavity of the top of the handheld housing 1 via a bearing to enhance stability. The telescopic tube 3 is slidably inserted inside the sleeve 1-1. A nut 3-1 is provided at the rear end of the telescopic tube 3 and screwed into the screw 2. A guide protrusion 3-2 is provided axially on the outer wall of the telescopic tube 3, which forms a sliding pair with a pre-made groove on the inner wall of the sleeve 1-1. Thus, the screw 2 and the telescopic tube 3 form a telescopic mechanism for adjusting the distance of the mechanical claw 5. The drive motor 4 is fixedly installed in the inner cavity of the top of the handheld housing 1 and is connected to the drive screw 2 via a gear set, serving as the power source for the telescopic mechanism. By rotating the drive motor 4 forward and reverse, the screw 2 rotates in both directions, thus realizing the telescopic movement of the telescopic tube 3 along the sleeve 1-1. Since the telescopic movement should not be too fast, the drive motor 4 can be a geared motor or the gear set can be a reduction gear set.

[0017] The mechanical gripper 5 includes a mounting base 5-1, a T-shaped control component 5-2, two gripping arms 5-5, and two transmission connecting rods 5-7. The mounting base 5-1 is coaxially mounted on the front end of the telescopic tube 3, preferably using a detachable connection method to allow the mechanical gripper 5 to be removed for cleaning and disinfection for future use. The longitudinal support arm of the T-shaped control component 5-2 extends into the telescopic tube 3 through a pre-drilled central hole in the mounting base 5-1 and is fixed with a magnetic suction part 5-3. A compression spring 5-4 is provided between the transverse support arm of the T-shaped control component 5-2 and the mounting base 5-1. The ends of the two gripping arms 5-5 are respectively hinged to both sides of the mounting base 5-1, and a chuck 5-6 is integrally provided at the top of each of the two gripping arms 5-5. The clamping end face should preferably adopt an arc-shaped hollow structure to reduce pressure on the tick and maintain its activity, which is helpful for subsequent research. The two transmission connecting rods 5-7 are respectively hinged to the middle position of the two clamping arms 5-5 and the end of the transverse support arm of the T-shaped control member 5-2. By moving the T-shaped control member 5-2 along the axial direction, the two transmission connecting rods 5-7 can be driven to realize the opening and closing action of the two clamping arms 5-5, thereby realizing the opening and closing of the clamp 5-6. Furthermore, without the action of external force, the clamp 5-6 can be kept in the open state due to the elastic support of the compression spring 5-4.

[0018] The electromagnet 6 is installed and fixed inside the telescopic tube 3 and is configured to cooperate with the magnetic suction part 5-3. By activating the electromagnet 6, the elastic force of the compression spring 5-4 can be overcome to attract and position the magnetic suction part 5-3, thereby causing the T-shaped control part 5-2 to move backward to close the clamp 5-6. Since the electromagnet 6 needs to move with the telescopic tube 3, the control line of the electromagnet 6 should be arranged in a spiral to avoid being pulled apart.

[0019] The battery 7, installed at the bottom of the handheld casing 1, supplies power to the drive motor 4 and the electromagnet 6. A removable rechargeable battery is preferable for easy reuse. A three-position switch 1-2 and a push-button switch 1-3 are located at the center of the front side of the handheld casing 1. The three-position switch 1-2 controls the forward, reverse, and stop operation of the drive motor 4, while the push-button switch 1-3 controls the start and stop of the electromagnet 6.

[0020] The rocker arm 8 is arranged in the front-to-back direction and is mounted on the handheld shell 1 via a torsion hinge. When no external force is applied, the front end of the rocker arm 8 rests against the handheld shell 1 under the action of the torsion hinge. When the hand is operated, the rear end of the rocker arm 8 is pressed by the thumb, and the front end is lifted under the action of the lever, so as to open the pangolin's scales and observe the situation under the scales.

[0021] In use, hold the handheld casing 1 with one hand, insert the front end of the pry bar 8 into the pangolin's scales, and press the rear end of the pry bar 8 with your thumb to lift the scales. Observe whether there is a tick under the scales. If there is, adjust the three-position switch 1-2 with your index finger to make the drive motor 4 rotate forward and control the extension tube 3 to extend until the mechanical claw 5 reaches the location of the tick. Adjust the three-position switch 1-2 with your index finger to stop the drive motor 4. Then, press the button switch 1-3 with your middle finger to activate the electromagnet 6. The electromagnet 6 attracts the magnetic part 5-3, causing the gripper 5-6 of the mechanical claw 5 to close and capture the tick. While keeping the button switch 1-3 pressed, adjust the three-position switch 1-2 with your index finger to make the drive motor 4 rotate in reverse and control the extension tube 3. The mechanical claw 5 retracts until it is fully retracted into the front end of the sleeve 1-1. The drive motor 4 is then stopped by adjusting the three-position switch 1-2 with the index finger. A transfer slot is integrally set at the bottom front end of the sleeve 1-1, corresponding to the position of the clamp 5-6, and a collection tube 9 is detachably installed. The collection tube 9 is connected to the sleeve 1-1. In this way, when the button switch 1-3 is released to stop the electromagnet 6, the clamp 5-6 resets and opens under the elastic support of the compression spring 5-4, and the tick can fall into the collection tube 9, completing one capture operation. When the telescopic tube 3 extends again, it can close the collection tube 9 to prevent the tick from escaping. This design can reduce the frequency of taking out and replacing the collection tube 9 and improve the operation efficiency.
