Detailed Description
The technical scheme of the utility model is further explained below with reference to the attached drawings.
In this scheme, as shown in fig. 1, one end of the energy storage spring is fixed on the fixed bracket, and the other end is fixed on the handle, and a user is required to pull the handle, so that the spring is stretched. In the scheme, the energy storage spring is fixed in the bracket, and the fixed point parts on two sides are increased through the rotation of the wrench, so that the total length of the support rod is prolonged, and then the spring is indirectly stretched. And is laborious.
The device structurally comprises a base, a compression block, a connecting plate, a compression wheel and a compression handle. The upper pressing block is limited by the baffle rod, the upper pressing block is pressed by rotation of the pressing wheel to enable the upper pressing block to move up and down, and the pressing wheel is connected with the pressing handle to be limited by the left connecting plate and the right connecting plate.
Before the device is used, the base is fixed on the workbench. When the device is used, the spring passes through the hole formed by the upper compression block and the lower compression block, one end of the spring hanging plate is required to be installed towards an operator, 3 to 4 circles of springs are reserved, the springs are matched with the internal threads of the compression blocks, the compression handle is pulled by hand to move downwards to drive the compression wheel to rotate, the upper compression block is extruded to compress the springs, the prepared spring hanging plate is screwed in along a spring gap, the relation between the working stress of the energy storage spring and the number of circles of the spring hanging plate is calculated, and the number of circles of the spring hanging plate required to be screwed in is judged. The pressing handle is pulled by hand to move upwards, the pressing wheel reversely rotates to release the upper pressing block, and the spring assembly can be conveniently taken down. And inserting the other end of the spring into the compression block, repeating the operation, and screwing the two ends of the spring into the spring hanging plate to complete the assembly of the energy storage spring.
