[0007] Furthermore, there are multiple limit clamping holes, and the limit clamping holes are evenly and equidistantly distributed.
[0008] Furthermore, the size of the clamping head of the position-limiting clamping seat matches the inner diameter of the position-limiting clamping hole, and the position-limiting clamping seat is clamped and connected to the position-limiting clamping hole.
[0009] Furthermore, a mounting groove is provided on one side of the fixed support rod, and the limit clamping seat is rotatably connected to the mounting groove.
[0010] Furthermore, one side of the position limiting socket is fixedly connected to an adjusting rope, and the other end of the adjusting rope is fixedly connected to an adjusting slider.
[0011] Furthermore, the adjusting slider is arranged in an I-shape, an adjusting slot is provided on one side of the fixed support rod, and the adjusting slider is slidably connected to the fixed support rod through the adjusting slot.
[0012] Furthermore, a movable rotating wheel is rotatably connected to the inner side of the fixed support rod, and the adjusting rope is slidably connected to the movable rotating wheel.
[0013] The beneficial effects of the utility model are:
[0014] Through the knife gate clamp, strong spring, limit clamp seat and adjustment slider, etc., when in use, according to actual use needs, if the length of the instrument is not suitable, the adjustment slider can be moved, and the slider pulls the adjustment rope to pull the limit clamp seat, so that the limit clamp seat drives the movable support to squeeze the strong spring. As the limit clamp seat rotates, it can gradually move out of the limit clamp hole. At this time, the fixed support rod and the movable sleeve can be pulled and adjusted until they are moved to the position of the appropriate limit clamp hole, and then released. Under the action of the spring, the structure is reset, and the limit clamp seat is clamped into the limit clamp hole to ensure that the instrument can Reasonable use. In summary, when the utility model is used, for some reused equipment, it is difficult to press down the baffle plate during operation to avoid the baffle plate being stuck, the operator's inflexibility and excessive force causing the baffle plate to break, or the baffle plate not being pressed down into place, or the baffle plate rebounding when pressed down, causing the operator to be injured, or causing the lock of the insulating gloves to be broken. This tool is made for this purpose, firstly, to protect the safety of the operator and the equipment to prevent injuries; secondly, to facilitate operation, quickly and efficiently; in addition, the device is also easy to adjust the length so that the length can meet people's usage needs.
