Description

Hand-operated module Technical Field The utility model relates to the technical field of hand-operated modules, in particular to a hand-operated module. Background The stability and the applicability of the hand-operated module play a key role in the normal running and operation effects of equipment when the hand-operated module is widely applied to the fields of machine manufacturing, experimental equipment, small industrial production and the like. At present, most common hand-operated modules in the market adopt a fixing mode of matching a preformed hole with a bolt, the hand-operated modules are installed on a workbench, the traditional installation mode depends on a corresponding installation hole preset on the surface of the workbench, and the hand-operated modules pass through the preformed hole and are screwed up through the bolt, so that the hand-operated modules are firmly connected with the workbench. However, this fixation method exposes significant drawbacks during actual use. For example, in some laboratory scenarios, the design of the work bench tends to be varied and specialized, and many laboratory work benches are not provided with mounting holes that match the hand-cranking module preformed holes. When needs are installed hand module on this kind of workstation, traditional preformed hole bolt fastening mode just can't be implemented, and this very big application range that has restricted hand module leads to it unable to satisfy diversified application demand, has influenced flexibility and the convenience of equipment installation, has also restricted the development of relevant work. Therefore, we propose a hand-operated module. Disclosure of utility model The utility model aims to provide a hand-operated module to solve the problems in the background art. In order to achieve the purpose, the utility model provides the following technical scheme that the hand-operated module comprises: The base is symmetrically and fixedly connected with sliding rods for providing support at the top end of the base, the outer walls of the two sliding rods are connected with pedestals in a sliding manner, and a first threaded rod for driving the pedestals is rotationally connected at the center of the top end of the base; The storage groove is symmetrically formed in two sides of the base, an extension rod for fixing the base is rotationally connected in the storage groove, and a limiting block is arranged in the extension rod; The limiting structure is arranged at the joint of the extension rod and the storage groove and used for limiting the extension rod; And the adjusting structure is used for adjusting the position of the limiting block. Preferably, the limiting structure comprises a first groove, a spring and an extrusion plate, wherein the inner wall of the storage groove is provided with the first groove, the center of the first groove coincides with the axis of the joint of the extension rod and the storage groove, the spring is fixedly connected inside the first groove, the extrusion plate is axially and slidably connected with the inner wall of the first groove, one end of the extrusion plate is fixedly connected with the spring, the other end of the extrusion plate is provided with friction lines, one side of the joint of the extension rod and the storage groove is in frosted design, and the friction lines of the extrusion plate are in contact with the frosted design end of the extension rod. Preferably, the adjusting structure comprises a second threaded rod, a threaded sliding block and a connecting groove, wherein the second threaded rod is rotationally connected to the inside of the extension rod, the threaded sliding block is slidingly connected to the inside of the extension rod, the connecting groove is symmetrically formed in the bottom end of the threaded sliding block, one end of the limiting block is rotationally connected with the connecting groove, and a torsion spring is arranged at the joint of the limiting block and the connecting groove. Preferably, one end of the first threaded rod extends out of the base and is fixedly connected with a crank. Preferably, one end of the second threaded rod extends out of the extension rod to form an inner hexagonal groove. Preferably, the length of the limiting block is greater than the length of the thread slider. Preferably, when the two extension rods are located in the storage groove, a gap exists at one end of each of the two extension rods, which is close to each other. Compared with the prior art, the utility model has the beneficial effects that: In the installation convenience, abandoned the traditional mode of preformed hole bolt fastening, through setting up storage tank, extension pole, limit structure and regulation structure, need not to punch in advance on the workstation, only need dial the extension pole according to the workstation holding surface, after adjusting its angle, utilize regulation structure drive limit piece
