摘要： Disclosed is a quick-disassembly nipple connector structure, which is mainly composed of a hollow pipe, a pivoting assembly, a screwing member, a plurality of gripping jaws, a sleeve, a handle and a spring. The handle is additionally disposed on the sleeve and the pivoting assembly; when the handle is not pulled, the sleeve is located at a lock position to lock a grease nipple; and when the handle is pulled downwards, the sleeve is located at a release position to release the grease nipple. The quick-disassembly nipple connector structure can be rapidly switched to the lock position or the release position, thus, facilitating operation, shortening the work time, achieving accurate alignment, improving work efficiency, and avoiding damage to internal parts caused by excessive force application by users.

摘要： An exhaust device for a grease gun includes: a grease output valve, a normally closed unit, an exhaust valve and an adjusting member. The integral design of the exhaust valve and the adjusting member provided on the grease output valve enables the adjusting member to be adjusted to the exhaust position during the exhaust operation, so that the blocking portion of the adjusting member does not block the exhaust hole from the exhaust passage but allows the exhaust hole to communicate with the exhaust passage. At this time, the air in the grease output passage of the grease output valve can be exhausted through the exhaust passage and the exhaust hole, so that the grease gun can smoothly pump out grease.

摘要： A grease gun with an adjustable operating angle includes: a grease barrel having a first annular assembling portion and a first annular pivot portion; a gun body having a second annular assembling portion facing the first annular assembling portion and a second annular pivot portion to be pivotally disposed on the first annular pivot portion; a positioning ring fixed to the second annular assembling portion and having annularly arranged positioning cavities and facing the first annular assembling portion; and a positioning unit having a positioning member movable between a locked position and a release position, and the positioning member having a positioning portion to be inserted into or disengaged from the positioning cavities. The grease barrel and the gun body can be rotated and fixed relative to each other after rotation to adjust the angle between the two, which consequently reduces the space limitation on the grease feeding operation.

摘要： Disclosed is a quick-disassembly nipple connector structure, which is mainly composed of a pipe, a pivoting assembly, a screwing member, a plurality of gripping jaws, a sleeve and a handle. The handle can be pulled by users to enable the quick-disassembly nipple connector structure to be rapidly connected to or separated from a grease nipple. When the handle is pulled downwards, the sleeve is located at a lock position to lock the grease nipple; and when the handle is pulled upwards, the sleeve is located at a release position to release the grease nipple. Thus, the quick-disassembly nipple connector structure has the advantages of being capable of improving work efficiency, high in positioning speed, high in accuracy and good in fixing property and has a good overall constituent strength, so that the motion stability is improved, and the operation smoothness and service life are ensured.
