摘要： A socket includes a first section and a second section. The first section is to be connected with a tool. The second section includes an outer face, and a mounting hole is axially defined through the second section and communicates through the first section. The mounting hole includes multiple recesses and multiple sides defined in the inner periphery thereof. The multiple recesses and the multiple sides are located alternatively with each other. Each recess includes a rounded corner formed radially in the inner portion thereof. A triangular groove is formed axially and centrally in each side. The angle between two insides of each groove is smaller than 90 degrees. A rusted or damaged bolt head is engaged with either the rounded corners or the grooves so as to be effectively rotated.

摘要： The present disclosure discloses a carburetor, including a fuel passage and an oil passing passage. The fuel passage communicates with the float chamber. The carburetor further includes a magnetic sleeve assembly, a magnet assembly and a thimble assembly. The magnetic sleeve assembly is fixed to a float base and a first end of the magnetic sleeve assembly extends into the oil passing passage and is connected to a body. The first end of the magnetic sleeve assembly includes a fuel passing hole and a passage, the fuel passing hole communicates with a float chamber. The passage communicates the oil passing passage. Both the thimble assembly and the magnet assembly are installed in the magnetic sleeve assembly. The thimble assembly is configured for cutting off the passage under driving of the magnet assembly to cut off a communication between the oil passing passage and the float chamber.

摘要： A ratchet ring includes six first driving portions formed to the inner periphery of the ratchet ring. Each first driving portion includes a first driving face and a toothed face. A second driving portion is formed in each of the six first driving portions and includes two second driving faces which respectively extend from the first driving face and the toothed face. A first angle is formed between the two second driving faces. A third driving portion is formed in each of the six first driving portions and includes a recess located between the two second driving faces. A second angle is formed between two sides of the recess. A step is formed between the two second driving faces and the third driving portion. When a corner of an object is engaged between the two second driving faces, the step avoids the object from dropping from the ratchet ring.

摘要： The method and system utilized the measurement of the “absolute” velocities or equivalent parameters of the electromagnetic devices and objects, which are defined as the velocities relative to the real origin of the electromagnetic wave, to accurately picture their impacts on the propagation and measurement of the electromagnetic wave and compensate for these impacts correspondingly. The comprehensive information of the “absolute” velocities, including both the measured values and the calculated right timings, is utilized to calibrate and control the electromagnetic device and calculate the results to improve performance and accuracy. The method and system include the absolute velocity measurement, the calibration and control of the device, and the computation of the right timings and results.

摘要： A hand tool with angle adjusting mechanism includes a handle, a driving head, an engaging assembly and a button. The handle has a receiving groove, a transverse hole and a longitudinal hole. The driving head has a connecting portion disposed in the receiving groove. The engaging assembly has an engaging member and a spring. The engaging member has an engaging tooth at a top thereof for engagement with the driving head, and has an arc-shape pushing groove in a lateral side with an arc-shape wall inside thereof. The button is movably disposed in the transverse hole of the handle, and has an abutting portion slidably inserted in the arc-shape pushing groove, the abutting portion of the button has an arc-shape plane abutting against the arc-shape wall such that horizontal movement of the button drives the engaging member to move longitudinally along the longitudinal hole of the handle.

摘要： A one-step starting carburetor includes a body, and a pulse generator and an oil pumping unit which are connected with the body. The oil pumping unit can produce an oil pumping function to pump fuel from an oiler to the carburetor when a flywheel of an engine is revolving. When the carburetor is operating, it only needs to pull a starting line and does not need to extrude an oil pumping ball to pump the fuel for the carburetor or to close a choke valve. After hearing a voice like ‘poop-poop’, it does not need to half open the choke valve to warm the engine or to open the choke valve after warming the engine. Thus the operation of the carburetor is simple for users' convenience.

摘要： A carburetor improves the starting performance of an engine. The carburetor includes a main body, a pump oil ball and a fuel-air mixing channel which extends through the main body. The pump oil ball is mounted to an air strangler spindle via a spiral groove. When the pump oil ball is pressed, the air strangler spindle is driven to rotate by the spiral groove and thus to control the air strangler spindle between the fully open state and the fully closed state. The carburetor dramatically improves the starting performance of the engine.

摘要： A telescopic wrench includes an outer tube, an outer sleeve, and an inner rod. The first hole of the outer sleeve ring is fitted onto the outer tube, and the second hole of the outer sleeve provides peripheral contact with the rod section of the inner rod. The outer sleeve forms an external auxiliary fitting structure with the inner rod and outer tube. The telescopic wrench provides an improvement over known structures that are prone to loosening and noise during use. The telescopic wrench enhances the structural strength when subjected to operating forces.
