Once the rod-shaped workpiece is arranged in the inner clamping tube, the pull rod drives the inner clamping tube to retract into the outer clamping tube, the clamping pieces at the outer end of the inner clamping tube are extruded by the outer clamping tube, and the rod-shaped workpiece is stably clamped by the clamping pieces. Meanwhile, the bolt is embedded in the first connecting hole and the second connecting hole at the same time, so that the whole clamp is always in a clamping state.
In the manual clamp, the bolt is sleeved with the spring, two ends of the spring respectively act on the bolt and the outer clamping pipe, and the bolt tends to be embedded in the second connecting hole under the elastic force action of the spring.
The manual clamp can be stably in a clamping state under the elastic force action of the spring.
In the manual clamp, the inner side of the clamping piece is fixedly connected with a flexible gasket which is made of rubber materials.
The gasket can prevent the rod-shaped workpiece from directly and rigidly contacting the clamping piece.
Compared with the prior art, the manual clamp can stably clamp the rod-shaped workpiece through the moved outer clamping pipe only by pulling the hand wheel, so that the manual clamp is simple and convenient to operate and use.
Meanwhile, the inner clamping pipe is positioned in the outer clamping pipe, and the outer clamping pipe and the hand wheel are stably connected to the rack, so that the whole clamp is compact in structure, simple in structure, low in cost and high in practical value.
