The invention relates to the technical field of front clamping type jacks, and particularly relates to a front clamping type jack with a tool anchor built-in structure for a small space. The front clamping type jack comprises an oil cylinder and a steel strand, wherein a piston is connected to the inner side of the oil cylinder in a sliding mode, a supporting sleeve is fixedly connected to the right end of the piston, a penetrating sleeve is connected to the inner side of the supporting sleeve in a sliding mode, the penetrating sleeve is in sliding connection with the piston, a positioning sleeve is fixedly connected to the left end of the inner side of the penetrating sleeve, a limiting plate is arranged at the right end of the supporting sleeve, and a working anchor plate is arranged at the right end of the limiting plate. According to the front clamping type jack, a tool clamping piece, the tool anchor plate, the piston, the working anchor plate and a spring are arranged, when the device is used, a tool anchor is arranged in the device, so that the tool anchor is convenient to disassemble and assemble, meanwhile, the space required by tensioning of the jack is effectively saved, the jack is suitable for tensioning in a narrow space, a large amount of prestressed steel strand materials are saved, the operation is simple and convenient, the overall size of the device is compact and simple, the stress is clear, the operation is safe, the operation efficiency is improved, and the construction progress is accelerated.

    本发明涉及前卡式千斤顶技术领域,尤其为一种小空间使用具有工具锚内置结构的前卡式千斤顶,包括油缸和钢绞线,所述油缸内侧滑动连接有活塞,所述活塞右端固定连接有撑套,所述撑套内侧滑动连接有穿心套,且穿心套与活塞滑动连接,所述穿心套内侧左端固定连接有定位套,所述撑套右端设有限位板,所述限位板右端设有工作锚板,本发明中,通过设置的工具夹片、工具锚板、活塞、工作锚板和弹簧,在使用装置时,通过将工具锚内置,从而方便了工具锚的拆装,同时有效地节省了千斤顶张拉所需的空间,适合狭小空间的张拉,大量节约了预应力钢绞线材料,操作简单方便,且装置整体尺寸紧凑简洁,受力明确、作业安全,提高了作业效率,加快了施工进度。
