Abstract
The utility model relates to a lifting device which belongs to the technical field of an auxiliary device of an electric tool. The utility model is characterized in that the lifting device comprises a base and an upper bracket, wherein connecting rods which are matched with each other in a hinge mode are respectively arranged at the front of the base and the back surfaces of the upper bracket. One end of a screw rod is matched with the base in a rotary mode and is connected with a rotary hand wheel in a rotary mode, and the other end of the screw rod is matched with the lower end of each connecting rod through a transmission shaft in a transmission mode. The lifting device has the advantages of reasonable structure and simple and convenient use. The upper bracket can be lifted by rotating the rotary hand wheel to change the angle between the two connecting rods, and thus, the upper bracket can reach the same height as that of a working table top of the electric tool. The utility model is used for placing large and long workpieces, and processed workpieces are placed stably. The cutting surfaces of the workpieces are smooth, and the cutting precision is enhanced.
Description
Technical field
The utility model belongs to power tool accessory equipment technical field, is specially a kind of jacking system.
Background technology
Desk type electric tools comprises bench saw, diagonal cutting saw, cutting machine etc., because the bench board of fuselage itself limits, area of work is changeless, can produce workpiece adding the section chief during big workpiece and put phenomenons such as shakiness, cause the unfairness of work piece cut face, influence cutting accuracy.
The utility model content
The utility model is to overcome the problems referred to above that prior art exists, and design provides a kind of technical scheme of jacking system, can shelve long and big processing work, and it is stable to make work put.
Described a kind of jacking system, it is characterized in that comprising base, upper bracket, base, forward and backward connecting rod that hinged cooperation is set respectively of upper bracket, screw mandrel one end cooperates with the base rotation, and be rotationally connected with rotation hand wheel, the screw mandrel other end cooperates with the transmission of connecting rod lower end by transmission shaft.
Described a kind of jacking system, its in feature in connecting rod lower end and base bearing fit, at least one end of small end and upper bracket bearing fit.
Described a kind of jacking system, it is equipped with in upper bracket in feature and rolls bar.
Described a kind of jacking system is characterized in that the connecting rod lower end by rivet, packing ring and base normal-running fit, and the transmission shaft outer end that cooperates with the connecting rod lower end is provided with circlip for shaft.
Described a kind of jacking system is characterized in that connecting rod passes through the hinged cooperation of rivet.
Described a kind of jacking system is characterized in that forward and backward of base is provided with support foot respectively.
Described a kind of jacking system is characterized in that rolling the bar two ends respectively by plug, locating dowel pin and spring and upper bracket normal-running fit.
Above-mentioned a kind of jacking system, rational in infrastructure, use simple, convenient, change angle between two connecting rods by rotating rotation hand wheel, upper bracket is risen, reach the same height of power tool work top, be used to shelve long and big workpiece, it is stable to make processed workpiece put, and the work piece cut face is more smooth, has improved cutting accuracy.
