Description

[Technical Field]

[0001] The present invention relates to the technical field of daily necessities, and in particular to manual tweezers. [Background technology]

[0002] Tweezers are tools used to pick up lumps of chemicals, metal particles, hair, fine thorns, and other small objects. They are used in repairing mobile phones and can also be used to hold wires, components, and pins of integrated circuits. There are many types of tweezers and their range of applications is relatively wide, so different tweezers are required for different tasks.

[0003] The physical principle on which tweezers operate is the principle of leverage, the effect of force action, and the fulcrum of most tweezers is the adhesive part at the tip, but the entire structure at the bottom functions as a moment arm, and tweezers with an overall V-shaped structure do not have a moment arm, so a relatively large force is required to pick up an object, which means that force is required to use the tweezers. Therefore, tweezers are essentially two levers that require force, and when using tweezers in daily life, it is generally necessary to push the tweezers very close to the object, which affects the user's operating experience.

[0004] Therefore, conventional tweezers are cumbersome to use when picking up an object, are difficult to use, affect the user's experience, and are prone to breakage. Summary of the Invention [Problem to be solved by the invention]

[0023] 1 and 3, the present invention provides a pair of manual tweezers, which includes a main body 10, a first fixed base 20, a pusher 30, a tie rod 40, and a clamping arm 50. The first fixed base 20 is installed on one side of the main body 10. The pusher 30 is movably fitted onto the first fixed base 20 and moves back and forth along the axial direction of the first fixed base 20. The tie rod 40 has a first end and a second end, the first end of which is fixedly connected to the pusher 30, and the second end of which is connected to the clamping arm 50. The pusher 30 drives the tie rod 40 to move back and forth along the axial direction of the first fixed base 20 to open and close the clamping arm 50, thereby achieving stable opening and closing of the tweezers and making the tweezers easy to operate and use.

[0024] As shown in FIG. 2 , the manual tweezers further include a silicone sleeve 60 fitted over the pusher 30. The silicone sleeve 60 is generally made of rubber and is soft and elastic. Fitting the silicone sleeve 60 over the pusher 30 further protects the tweezers from wear and dirt. The silicone sleeve 60 also acts as an anti-slip device, preventing the tweezers from accidentally falling off. The silicone sleeve 60 has a very good feel and is of excellent quality. Users can print various patterns on the silicone sleeve 60 according to their preferences, creating beautiful and elegant designs that meet the user's personalized needs. Fitting the silicone sleeve 60 over the pusher 30 also simplifies the process of pressing the pusher 30 to open and close the clamping arm 50.

[0025] Referring to FIG. 1, a plurality of notches are provided at intervals on one side of the pusher 30, forming an elastic sheet 301. The side of the elastic sheet 301 facing the first fixed seat 20 is provided as a first inclined surface 302, and the side of the first fixed seat 20 facing the elastic sheet 301 is provided with a second inclined surface 201 that fits with the first inclined surface 302. In the initial state, the clamping arm 50 is in an open state, and the two inclined surfaces, the first inclined surface 302 and the second inclined surface 201, are in contact with each other, and the elastic sheet 301 is pushed in. When subjected to force, the first inclined surface 302 moves away from the second inclined surface 201 and moves in the axial direction of the pusher 30, thereby driving the tie rod 40 to move and closing the clamping arms 50. The user can easily pick up the item by applying a relatively small force to the position of the elastic sheet 301, saving effort. In addition, by controlling the pushing force, the opening and closing angle of the clamping arms 50 can be further controlled, thereby meeting the needs of using tweezers in different scenarios.

[0026] Referring to FIG. 1 , the manual tweezers further include a spring 70, a portion of which is fitted onto the first fixing seat 20, one end of the spring 70 abutting against the main body 10, and the other end of the spring 70 abutting against the pusher 30. The spring 70 is a return spring 70. When the pusher 30 is moved under pressure, the pusher 30 presses the spring 70, compressing it. When the pusher 30 is no longer under pressure, the compressed spring 70 returns to its original state. The spring 70 releases its elastic force to drive the pusher 30 to return, restoring the tweezers to their original state. This prevents the spring 70 from being damaged by being constantly compressed.

[0027] Referring to FIG. 2 , the manual tweezers include a second fixing seat 101, one end of the second fixing seat 101 is fixed on the main body 10, and the other end of the second fixing seat 101 is fixed on the first fixing seat 20. A position limiting groove 1011 is provided on the first fixing seat 20 to limit the position of the spring 70. One end of the spring 70 is fitted into the position limiting groove 1011, which limits the position of the spring 70. The second fixing seat 101 and the spring 70 are in contact with each other to prevent the spring 70 from jumping out under pressure, which would cause damage and affect the user's use.

[0028] Referring to FIG. 1 , a connecting seat 303 is protruding from the inner wall of the pusher 30. A first fixing hole 3031 is bored in the connecting seat 303 along the horizontal direction of the pusher 30. The tie rod 40 is fixed in the first fixing hole 3031. A second fixing hole 3032 is bored in the connecting seat 303 for installing a bolt along the vertical direction of the pusher 30 and communicating with the first fixing hole 3031. A locking block is protruding from the inner wall of the second fixing hole 3032 to facilitate fixing the bolt. The tie rod 40 can be fixed on the connecting seat 303 by tightening the bolt. When the pusher 30 moves, the connecting seat 303 and the tie rod 40 are driven to move together, thereby achieving the purpose of the tie rod 40 opening and closing the clamping arm 50. This achieves stable opening and closing of the clamping arm 50 and is easy to operate, making it convenient for users.

[0029] Referring to FIG. 2, a guide groove 202 that fits the connecting seat 303 is installed on the first fixed seat 20, and the connecting seat 303 is movably installed within the guide groove 202. The connecting seat 303 moves back and forth horizontally within the guide groove 202, and the guide groove 202 limits the moving direction of the connecting seat 303 and prevents the connecting seat 303 from turning over.

[0030] Referring to FIG. 1, a groove 203 for fixing the silicone sleeve 60 is formed on the outer wall of the first fixing seat 20, and a protrusion 601 that fits into the groove 203 is formed on the inner wall of the silicone sleeve 60. The groove 203 and the protrusion 601 fit tightly together to prevent the silicone sleeve 60 from falling off and to facilitate the removal and replacement of the worn silicone sleeve 60.

[0031] Referring to FIG. 1 , the manual tweezers further include a control board 102 and a camera 80. The control board 102 is installed inside the main body 10, which further has mounting cavities for mounting components such as a main board and a battery. The camera 80 is installed adjacent to the clamping arm 50 and is electrically connected to the control board 102. The clamping arm 50, the first fixing base 20, the pusher 30, and the second fixing base 101 are all provided with through-holes for installing electric wires. The electric wires are connected to one end of the camera 80 to supply power to the camera 80. The design of the camera 80 makes it easy for a user to clearly see the operating point when using the tweezers, allowing for more accurate operation. A small flashlight may also be installed on the camera 80, which can achieve the same effect even when using the tweezers in a dark environment, improving the user experience.

[0032] Referring to FIG. 1 , the manual tweezers further includes a support arm 90, which is fixedly installed on the first fixed seat 20. The support arm 90 has a first mounting passage 901 through which the tie rod 40 passes and a second mounting passage 902 for mounting the camera 80. The first mounting passage 901 limits the movement trajectory of the tie rod 40, further improving the stability of the movement process of the tie rod 40. The second mounting passage 902 can be used to mount not only the camera 80 but also other items such as a light source, a magnifying glass, a laser, etc. The length of the support arm 90 is adjustable, so that when the force is the same, different needs for the length of the tweezers can be met.
