Description

Technical Field

[0001] The invention belongs to the technical field of experimental detection auxiliary facilities, and in particular relates to a pin extraction collector. Background Art

[0002] When food or materials are tested, some test specimens are stored in paper bags or plastic bags. These bags are often temporarily fixed with pins, thumbtacks or paper clips. After working for a period of time, there are often scattered nails on the table or the ground, which can easily cause injuries. Therefore, these scattered nails need to be cleaned up frequently. In existing work, they are usually picked up manually, and the picked up pins and thumbtacks need to be placed in a special box, which is not only time-consuming and laborious, but also easy to get injured. Therefore, it is necessary to design a device that can conveniently pick up thumbtacks and pins for such work scenarios. Summary of the invention

[0022] In the description of the invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the invention can be understood according to specific circumstances.

[0023] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0024] A pin extraction collector, such as Figures 1 to 3 As shown, it includes a hollow picking rod 1, two picking heads 2 are cross-arranged at the front end of the picking rod, and an end cap 3 is detachably installed at the rear end; the inner ends 4 of the two picking heads are both inside the picking rod, the inlets 6 of the outer ends 5 of the two picking heads correspond to each other, and the picking channel in the picking head gradually decreases from the outer end to the inner end, which is very convenient for the pin to be picked up smoothly (and enter the internal cavity of the picking rod), the picking channel is always connected to the storage cavity of the picking rod, a rear magnetic part 7 is installed in the end cap, and a rear magnetic part touch sensing switch 8 is provided in the picking rod, when the two picking heads are in a closed state, the inner end of the picking head triggers the rear magnetic part touch sensing switch, so that the rear magnetic part generates magnetic force.

[0025] A front magnetic piece 10 is provided at the front end of the pick-up rod, and the front magnetic piece is arranged on the outer wall of the pick-up rod, and a front magnetic piece touch sensing switch 11 is provided inside the pick-up rod. When the two pick-up heads are in the normal open state, the outer end of the pick-up head triggers the front magnetic piece touch sensing switch, so that the front magnetic piece generates magnetic force. It should be pointed out that the collector can install batteries in the inner cavity of the pick-up rod or in the end cap, and is provided with a main switch (or button) for controlling the battery switch. Before use, the circuit connected to the magnetic piece can be turned on by controlling the main switch (or button).

[0026] The end of the pickup rod away from the end cap corresponds to the inner end of each pickup head, and a retaining member 9 is provided. The retaining member generates a pulling force on the pickup head to keep the two pickup heads in an open state under normal conditions. As an example, the retaining member includes a spring. The front and rear magnetic members can both be electromagnets. After power is turned on, the magnetic force is enhanced to generate an adsorption force, and after power is turned off, the magnetic force is weakened or disappears, and the adsorption effect is lost. The front and rear magnetic member touch sensing switches can use contact electrode sheets. After the pickup head contacts the corresponding electrode sheet, the switch can be turned on, so that the magnetic force of the corresponding magnetic member is enhanced.

[0027] In an optional embodiment, a pressing handle 13 is provided on the outer surface of the pickup head. For example, the pressing handle adopts a circular plate structure, and the diameter of the pressing handle is larger than the width of the pickup head. Preferably, the pressing handle is made of non-conductive non-metallic material, so the pickup head material has little limitation, and can be made of metal material. By touching the induction switch with the metal material, the circuit where the corresponding magnetic part is located can be turned on. In addition, a protective cover 12 can be provided on the outside of the front magnetic part. Usually, the diameter of the middle part of the pickup rod is larger than the diameter of the two ends. The end cap is screwed on the pickup rod. The outer wall of the pickup rod is provided with anti-slip texture.

[0028] A rotating column is provided at the front end of the pick-up rod corresponding to each pick-up head, and the inner end of the pick-up head is rotatably mounted on the rotating column, and the rotating shaft only rotates with the outer wall of the pick-up head, and the end of the rotating shaft does not extend into the pick-up channel. In addition, the two pick-up heads can also be hinged by a rotating shaft, and the rotating shaft only rotates with the inner wall of the pick-up head, and the end of the rotating shaft does not extend into the pick-up channel. Such a structural design ensures that the two pick-up heads can be opened or closed around the hinge point, and will not cause loss of internal space in the pick-up channel, nor prevent the pins from falling into the storage cavity inside the pick-up rod. Of course, those skilled in the art can also adopt other structural forms as long as the above-mentioned technical effects can be achieved.

[0029] When in use, you only need to bring the opening of one of the picking heads close to and align it with the pin to be picked up, and then squeeze the two picking heads by hand to close them, and the pin can be picked up and put into the collector. Specifically, when the opening of the picking head is close to the pin to be picked up, the pin is sucked into the picking channel with the help of the adsorption force of the front magnetic part, and falls to a position close to the front magnetic part. At this time, as the two picking heads are closed, the inner end of the picking head no longer touches the front magnetic part touch sensing switch, so the front magnetic part no longer generates adsorption force on the pin. As the inner end of the picking head touches the rear magnetic part touch sensing switch, the rear magnetic part generates adsorption force to adsorb the pin into the storage cavity, completing the picking operation.

[0030] The invention has a simple structure. By arranging a picking head on the picking rod, the pins can be conveniently picked up and stored in the storage cavity, and the picking and storing functions are combined. Through the arranged magnetic part, the pins can be quickly adsorbed to the inside of the picking rod, which is convenient, fast, time-saving and labor-saving, and will not prick fingers, with good safety.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
