Introduction
A manual screw springening tool, single head, double-headed multi-gauge movable handle ratchet wrench (fixed hole). By the different specifications of the size of the main plum blossom sets and from the plum blossom sets through the hinge key of the key and the male key bite way to connect. Since a plum blossom has two sizes of plum-shaped through holes, it can be used for the tightening of the two sizes of screws, thus expanding the scope of use, saving raw materials and working hours. The movable trigger can easily adjust the wrench angle. This wrench for the screw tightening operation, with a strong applicability, easy to use and low cost characteristics.
2 principle & nbsp;
A ratchet wrench for rotating a bolt or nut in a narrow or difficult-to-close position, the ratchet wrench being rotatably connected to the end of the operating rod. The ratchet wrench includes a weight connected to the operating rod, the weight being slidable in the longitudinal direction of the operating rod, and having a front weight bearing portion for blocking the mass impact on the operating rod at the front of the weight. Or a rear weight loading portion for blocking the impact of the weight on the operating lever at the rear of said weight. Further, the operating lever may also have both a front weight bearing portion and a rear weight bearing portion.
3 Product Features & nbsp;
Pneumatic bar top cover device, open the lid more effort, smooth, fast.
Safety cylinder lock device, more solid, better anti-theft performance.
Sand paint the surface, anti-scratch, anti-dissolution, anti-rust ability.
Unique lid and box combination structure, solid and strong.
Special design of the heavy R angle drawer handle, pull together convenient.
Double ball slide design, self-locking function.
Wrapped plastic side handle, drag more easily.
Ratchet wrench
4 difference between ratchet wrench and torque wrench & nbsp;
Ratchet sleeve wrench 1. A manual screw elastic tool, single head, double-headed multi-gauge movable handle ratchet wrench (fixed hole). By the different specifications of the size of the main plum blossom sets and from the plum blossom sets through the hinge key of the key and the male key bite way to connect. Since a plum blossom has two sizes of plum-shaped through holes, it can be used for the tightening of the two sizes of screws, thus expanding the scope of use, saving raw materials and working hours.
The movable trigger can easily adjust the wrench angle. This wrench for the screw tightening operation, with a strong applicability, easy to use and low cost characteristics.
2. Torque wrenches - also known as torque wrenches or torque wrenches, torque is the product of force and distance, fastening screws and nuts and other threaded fasteners need to control the size of the torque required to ensure that the thread tight and not due to torque Too much damage to the thread, so use a torque wrench to operate. First set a required torque limit, when the torque applied to the set value, the wrench will issue a "Kata" sound or wrench connection bend a little angle, which means that there is no need to tighten the force. 3. The difference between them is that the torque wrench torque can be set. Torque wrench (torque wrench) issued the principle of the tower is very simple, can be divided into the following steps to understand: 1, torque wrench in the issue of " After the sound is prompted to have reached the required torque value;
3, the torque wrench issued by the "Kata" is generated by its own internal torque release structure, its structure is divided into pressure spring, torque release joints, torque mandrel composed of three structures.
4, first set the required torque on the torque wrench (by the spring set on the mandrel to the torque release joint pressure), lock the torque wrench, began to tighten the bolt. When the bolt reaches the torque value (when the use of torque greater than the spring pressure), will produce the effect of instantaneous out of touch. In the produce dislocation effect of the moment issued a joint percussion, wrench metal shell issued by the "Kata" sound. This is to confirm the torque value to remind the role (in fact, as our arm joints into a 15 degree bend on the iron tube in the moment after the straight will encounter the same principle).
Is the most commonly used manual torque wrench, in addition to electric torque wrench, pneumatic torque wrench and so on.
Structural torque wrench, also known as torque meter, torque screw screw. It is based on the principle of beam bending, torsion bar bending principle and the principle of compression of the coil spring designed to measure the role of the torque on the nut size.
Torque wrench and flat plate and dial type two. Torque wrench has a long elastic rod, one end with a handle, the other end with a square head or hex head, in the square head or hex head set a changeable sleeve, with steel beads stuck. On the top is also equipped with a long pointer. The scale plate is fixed on the handle seat with a scale value of 1N (or kg / m). Before use, first adjust the indicator mounted on the wrench to the required torque, and then pull the wrench, when the predetermined torque, the indicator pointer will be on the side of the pin rotation, the last pointer and pin collision , Through the speaker signal or sensor signal to inform the operator
