Abstract: An anchor preserves the seal on an oscillating polishing rod in a pumpjack. The anchor has first and second sidewalls. The sidewalls are joined and oriented in opposite directions to create a cylindrical sidewall for the anchor.

The radial hinge couples the first sidewall relative to the second sidewall and facilitates the opening and closing of the cylindrical sidewall to create a clamping area in the locked position. A transverse hinge extends in an orthogonal direction relative to the radial hinge. The transverse hinge supports a rotating shaft on the exterior surface of the sidewall. A clasp on the opposite end of the shaft selectively and optionally locks the first sidewall relative to the second sidewall to create the clamping area of the anchor.

Abstract: An oil and gas fracturing tool is disclosed, mainly involving a fracking tool with an electromagnetic intelligent control sliding sleeve including an outer sleeve section, a dart body section and a control section. The outer sleeve section is at the target location to be fractured. The effect of fracturing is mainly achieved by the dart body, which has an activated state and an inactive state. The initial state is inactive, and the front locking tip can be deformed under pressure during displacement. The diameter can change to pass through any sliding sleeve. When the dart body is counted and is about to reach the fracturing position, the front locking tip is blocked from deformation and cannot be reduced in diameter, thus pressurizing to control the fracturing effect. The control part includes a sensor module, a drive module, a main control module and a power supply module.
