Abstract

An embodiment of the invention discloses a clutch. A ratchet surface of a clutch pawl of the clutch can be connected with a chain link pin shaft in a combining / separating manner to transmit power, twoarm clamp driving pins are arranged on a clutch shell and arranged in sliding grooves of corresponding upper jaw arm clamps of a clamp in a penetrating manner respectively, therefore, the two upper jaw arm clamps are driven to slide on the clutch shell, and limiting is conducted. The clutch is installed on a rack of the pile puller, power transmission and clamp locking are achieved at the same time, a small pile body can be pulled out conveniently and reliably, and high cost performance is achieved.

Description

technical field [0001] The invention relates to the technical field of power tools, in particular to a pile extractor and its clutch, which is especially suitable for small projects such as garden construction. Background technique [0002] For occasions such as garden construction, often need to carry out pile extraction operation, be about to be placed in the square or circular pile of other types of soil layer and pull out ground. When pulling out the pile, the pile body is generally tightened with a steel wire rope, and then the hoist is started to take up the wire rope to remove the pile body from the soil layer. There is a problem that the wire rope locking operation is not convenient and reliable enough. There are also special clamps for pile extraction. The pile extraction is realized through the retraction and lifting of the two clamp arms. During operation, the clamp arm needs to be locked by the locking device, and then the motor is connected to drive the clamp to...
