The invention relates to a soil preparation furrowing device for forest planting of the forest industry, and relates to a furrowing device which is particularly suitable for the artificial forest planting in a large-area fish-scale pit way on low-pitched land in arid and semi-arid planting areas. The fish-scale pit furrowing device mainly comprises a plough body (1), a deep-digging cutter (2), a side-wall cutter (3), a measure and control land wheel (10), a main frame (4), a three-point suspension rack (7), an electric control system and a hydraulic control system, wherein the electric control system transmits signals about the furrowing size of each fish-scale pit and a distance size between every two adjacent fish-scale pits on the ground to an electric control box system through an electric sensing plate on the measure and control land wheel (10) to further control the hydraulic control system, so that the plough body (1) and the side-wall cutter (3) on a rear frame act from top to bottom according to the control requirements. The fish-scale pit furrowing device has advantages that the fish scale pit furrowing device can be connected with any tractor with 120horsepower or more in China, the overall layout of the structure is reasonable, the hydraulic system is simple, and convenience and reliability in transmission can be realized; and the distance measuring precision of the fish-scale pit is high, and the size of the pit can be adjusted at any time.

A stretching device has a housing; a first clamping member attached to a first portion of the housing; a second clamping member attached to a second portion of the housing; wherein the first clamping member has a movable pivot member such that an angle of contact between the first clamping member and a workpiece to be gripped remains constant regardless of the workpiece's thickness. A stretcher assembly has a first stretcher having a first housing having a first clamping member and a second clamping member opposed to each other; and a second stretcher having a second housing having a third clamping member and a fourth clamping member opposed to each other; and a workpiece support member interposed between the first stretcher and the second stretcher, wherein the first and third clamping members each includes a movable pivot joint such that an angle of contact of the first and third members with a workpiece to be gripped remains constant regardless of a thickness of the workpiece. The gripping force remains proportional to a stretching force.
