Cross wrench are usually made with clamps on one or both ends of the handle to apply external force to the handle to apply external force to turn the bolt or nut to hold the opening or sleeve of the bolt or nut. When in use, an external force is applied to the shank along the thread rotation direction, and the bolt or nut can be turned. The cross wrench is a hand tool that uses the principle of leverage to turn bolts, screws, nuts and other threads to hold the openings or sleeves of bolts or nuts. It is mainly used to disassemble the locking screws on the car tires. The traditional The cross wrench generally includes two rods welded together in a crisscross shape. This structure cannot slide, the force of both hands is unstable, the torque of one hand is not enough, it is not convenient to store, and the volume is large, and it is not convenient to pack, carry and store. . At present, there are also two poles that can slide, but there is no lock pin, which is very insecure during use. It mainly includes a main acting rod and a side-effect rod, wherein a transverse through hole is provided in the thickened middle section of the main acting rod for the insertion of the side-effect rod to form a cross state, and on the side of the lateral through hole, and A longitudinal deep hole communicating with the through hole is provided for inserting a push button in cooperation with an elastic member and a positioning member, and the middle section of the push button is a narrow section, and the lower section is a locking section.
Through the above-mentioned structural design, in conjunction with the first and second clamping slots provided on the side effect lever, the insertion type of the two effect levers can be easily adjusted and locked to achieve the expected practical and safety performance. The wrench of this structure can be split, which greatly reduces the volume when packaging, but the positioning structure is more complicated, and the manufacturing process is more troublesome. It includes handles, sliding rod heads, sliding rods, extension rods and sleeves, and is characterized in that the handle is inlaid There is a plastic sleeve with a bushing inside the plastic sleeve, and a handle extension rod inside the handle. This kind of wrench is positioned by a steel ball spring, and the structure is relatively simple, but it is prone to wear and deformation over time, making the sliding rod positioning insufficient.
Therefore, the structure needs further improvement. The technical problem to be solved by the utility model is to provide a cross wrench with simple structure, detachable, safe and reliable use in view of the above technical status. A cross wrench includes a main rod and a cross rod. The middle of the main rod is provided with a shaft hole for the cross rod to be inserted. The feature is that the middle side of the main rod is provided with a transverse recess perpendicular to the shaft hole and to the inner wall of the shaft hole In the communicating positioning groove, a lock pin is telescopically limited and arranged in the positioning groove. A first spring is supported between the lock pin and the bottom of the positioning groove to make the head of the lock pin extend out of the positioning groove. The middle part of the crossbar and Both ends are formed with a ring-shaped limiting concave ring, and the middle of the lock pin is formed with a locking part that cooperates with the limiting concave ring to lock and locate. When the head of the lock pin is pushed out under the action of the first spring, the lock The locking part of the pin is coordinated and positioned with the limiting concave ring.
Cross-shaped wrench, using the principle of leverage to turn bolts, screws, nuts, and other threaded hand tools that hold the openings or sleeves of bolts or nuts. Wrench is a hand tool commonly used in daily life. If you want to do a good job, you must use it first. When you have good tools, you should also understand how to use them. What is the classification of wrenches? Common wrenches in daily life include socket wrenches, ratchet wrenches, box wrenches, open wrenches, etc. What is the purpose of these wrenches? how to use? What are the specifications? A fixed size opening located at one or both ends, used to twist nuts or bolts of a certain size.General purpose tools are necessary tools for assembling machine tools or parts, transportation and maintenance of agricultural machinery. Use: It can be inserted up and down, or directly inserted when in use. Cross wrench manufacturers tend to take care of their cars and pay attention to their maintenance. But every car always has some maintenance parts that we can't reach or think of. Although these parts are difficult to reach, they play a vital role in driving safety, or can affect the braking performance and fuel consumption of the car, and some even affect the life safety of the car owner.
