扳手的基本分类

Basic classification of wrenches

　　1．呆扳手：一端或两端制有固定尺寸的开口，用以拧转一定尺寸的螺母或螺栓。

1. Open end wrench: A fixed size opening made at one or both ends, used to turn a nut or bolt of a certain size.

　　2．梅花扳手：两端具有带六角孔或十二角孔的工作端，适用于工作空间狭小，不能使用普通扳手的场合。

2. Box wrench: With working ends with hexagonal or hexagonal holes at both ends, it is suitable for situations where the working space is narrow and ordinary wrenches cannot be used.

　　3．两用扳手：一端与单头呆扳手相同，另一端与梅花扳手相同，两端拧转相同规格的螺栓或螺母。

3. Dual use wrench: One end is the same as a single end solid wrench, and the other end is the same as a ring wrench. Tighten bolts or nuts of the same specification at both ends.

　　4．活扳手：开口宽度可在一定尺寸范围内进行调节，能拧转不同规格的螺栓或螺母。该扳手的结构特点是固定钳口制成带有细齿的平钳凹；活动钳口一端制成平钳口；另一端制成带有细齿的凹钳口；向下按动蜗杆，活动钳口可迅速取下，调换钳口位置。

4. Monkey wrench: The width of the opening can be adjusted within a certain size range, and it can rotate bolts or nuts of different specifications. The structural feature of this wrench is that the fixed jaws are made into a flat concave pliers with fine teeth; One end of the movable jaw is made into a flat jaw; The other end is made into a concave jaw with fine teeth; Press down on the worm gear, and the movable jaws can be quickly removed to change the position of the jaws.

　　5．钩形扳手：又称月牙形扳手，用于拧转厚度受限制的扁螺母等。

5. Hook wrench: also known as crescent wrench, used to turn flat nuts with limited thickness.

　　6．套筒扳手：一般称为套筒:它是由多个带六角孔或十二角孔的套筒并配有手柄、接杆等多种附件组成，特别适用于拧转地位十分狭小或凹陷很深处的螺栓或螺母。套筒有公制和英制之分，套筒虽然内凹形状一样，但外径、长短等是针对对应设备的形状和尺寸设计的，没有统一规定，所以套筒的设计相对来说比较灵活，符合大众的需要。套筒扳手一般都附有一套各种规格的套筒头以及摆手柄、接杆、万向接头、旋具接头、弯头手柄等用来套入六角螺帽。套筒扳手的套筒头是一个凹六角形的圆筒；扳手通常由碳素结构钢或合金结构钢制成，扳手头部具有规定的硬度，中间及手柄部分则具有弹性。

6. Socket wrench: commonly known as a socket: it is composed of multiple sockets with hexagonal or twelve corner holes and equipped with various accessories such as handles and extension rods. It is particularly suitable for turning bolts or nuts with very narrow positions or deep depressions. Sleeves are divided into metric and imperial systems. Although the concave shape of the sleeve is the same, the outer diameter, length, etc. are designed according to the shape and size of the corresponding equipment. There is no unified national regulation, so the design of the sleeve is relatively flexible and meets the needs of the public. Socket wrenches generally come with a set of socket heads of various specifications, as well as swing handles, extension rods, universal joints, screwdriver joints, elbow handles, etc., used to fit hexagonal nuts. The socket head of a socket wrench is a concave hexagonal cylinder; Wrenches are usually made of carbon structural steel or alloy structural steel, with the wrench head having a specified hardness and the middle and handle parts having elasticity.

　　7．内六角扳手：成L形的六角棒状扳手，专用于拧转内六角螺钉。内六角扳手的型号是按照六方的对边尺寸来说的，螺栓的尺寸有标准。

7. Hexagonal wrench: A hexagonal rod shaped wrench in an L-shape, specifically designed for turning hex screws. The model of the internal hexagonal wrench is based on the size of the opposite side of the hexagon, and the size of the bolt has national standards.

　　用途：紧固或拆卸机床、车辆、机械设备上的圆螺母用。

Usage: Specially used for tightening or dismantling round nuts on machine tools, vehicles, and mechanical equipment.

　　8．扭力扳手：它在拧转螺栓或螺母时，能显示出所施加的扭矩；或者当施加的扭矩到达规定值后，会发出光或声响信号。扭力扳手适用于对扭矩大小有明确地规定的装配。

8. Torque wrench: It can display the applied torque when tightening bolts or nuts; Or when the applied torque reaches the specified value, a light or sound signal will be emitted. A torque wrench is suitable for assembly where the torque size is clearly specified.
