摘要： Pliers with a restoring function include an elastic element and two pliers bodies. The elastic element has two urging ends. The two pliers bodies have two pinching heads, two handles, and two pivotal parts. Each of the pivotal parts has a recess and a pivotal hole. A pivotal element goes through the two pivotal holes. The elastic element is disposed in the two recesses and penetrated by the pivotal element. Both urging ends of the elastic element are on opposite sides of the two recesses to urge sidewalls of the recesses, thereby opening the pliers. A buffer region is designed in each of the recesses for the corresponding urging end. When the opening angle of the pliers is greater than that is supported by the elastic element, at least one urging end of the elastic element releases its urging against the recess sidewall and moves in the buffer region. The pliers become relaxed then.

摘要： A pliers includes a first body with an engaging groove and a second body with an elongated slot pivotally connected with each other. The elongated slot includes a left and right positioning grooves and a protruding portion disposed therebetween. A tap button is pivotally connected to the second body. A supporting member is disposed between the second body and the tap button. When the first body comes close to the second body, the tap button can be tapped to a first position and engaged in the engaging groove. Thus, the first body is blocked and cannot pivot relative to the second body. The tap button can be tapped to a second position and detached from the engaging groove. Thus, the first body is pivotable relative to the second body. A positioning block is extending from the tap button and can be engaged in any of the positioning grooves for positioning the tap button.

摘要： A pliers has guiding surfaces at tooth portions of the first pliers body and tooth portions of the engaging unit of the control member. Therefore, when the pressing block of the control member is not pressed, even if the first pliers body is engaged with the tooth portions of the engaging unit, the second pliers body can still be pushed forward relative to the first pliers body, so that the second guiding surfaces of the second tooth portions of the engaging unit slide relative to the first guiding surfaces of the first tooth portions and each of the first tooth portions is moved to engage with a next corresponding second tooth portion, thereby allowing the second pliers portion being movable toward the first pliers portion. Hence, the clamping distance of the pliers can be adjusted to match with an object to be clamped.

摘要： The circuit board with a heat dissipating structure is provided. A first grounding conductor layer is formed on a first surface of a substrate. A first insulting layer is formed on the first grounding conductor layer and defines a number of circuit element pin openings and a plurality of heat dissipating openings therein so that the first grounding conductor layer is exposed from the circuit element pin openings and the heat dissipating openings. A number of solder balls are disposed in the circuit element pin openings and contacted with the first grounding conductor layer. A number of heat dissipating structures are disposed in the heat dissipating openings and contacted with the first grounding conductor layer. The heat dissipating structures and the solder balls have an identical material. The method for manufacturing the circuit board is also provided.

摘要： A tool structure composed of two pivotally connected handles and a tool head. The handle pivot shaft of the handles is spaced from the head pivot shaft of the tool head by a certain distance to form a double-lever structure for saving strength. A pin member is fitted through each handle in parallel to the handle pivot shaft, whereby the pin members can be forced to axially move within the handles. Each pin member has a large diameter section and a small diameter section. When replacing the tool head, a user only needs to press the pin members of the handles with a hand. At this time, the large diameter sections of the pin members are detached from the insertion notches of the tool head to easily replace the tool head with another tool head with different usage. The replacement can be completed without using any tool. Therefore, the tool head can be quickly assembled with the handles.
摘要翻译：由两个枢转连接的把手和工具头组成的工具结构。手柄的手柄枢轴与工具头的头枢轴轴距一定距离，形成双杠杆结构，以节省强度。销部件通过每个手柄平行于手柄枢轴安装，由此销部件可以被迫在手柄内轴向移动。每个销构件具有大直径部分和小直径部分。更换工具头时，用户只需用手按压把手的销部件即可。此时，销构件的大直径部分从工具头的插入凹口分离，以便用另一种具有不同用途的工具头来容易地更换工具头。可以在不使用任何工具的情况下完成更换。因此，可以用手柄快速组装刀头。
