The adjustable puller is characterized in that: the main frame is provided with four connecting arms, wherein three connecting arms form included angles of 120 degrees, and one connecting arm is positioned between two connecting arms; the upper parts of the pulling legs are provided with through grooves, and the pulling legs are arranged on the connecting arms of the main frame; the through grooves can slide along the connecting arms of the main frame; and the connecting arms are provided with circular holes, and springs and pin shafts are arranged in the circular holes to prevent the pulling legs from sliding out of the ends of the connecting arms. The adjustable puller has simple and reasonable structure, and is easy to manufacture, low in cost and convenient to install and use; and because the pulling legs can slide on the connecting arms, the distance between the pulling legs can be changed, and detachment of parts of multiple sizes can be realized.
Description
Technical field
The utility model relates to a kind of machine components dismounting hand-operated tools, specifically a kind of adjustable horse of drawing.
Background technology
Draw horse to have brought very big convenience for the installation and removal workpiece as a kind of instrument.In existing technology, common draw horse by body frame, pull bar, draw leg etc. to form, draw the leg that draws of horse normally to maintain static, the horse of drawing of general certain model is merely able to dismantle the machine components of certain size.Therefore draw the diameter of Ma Suoneng drawing workpiece often to be subjected to drawing the restriction of horse specification, versatility is poor.
Summary of the invention
The purpose of this utility model is in order to solve the deficiency of above-mentioned technology, to provide a kind of simple in structure, and low, the easy manufacturing of cost is flexible and convenient to use, can adjust big adjustable of the opening amount scope of application and draw horse.
The utility model solves the technical scheme that its technical deficiency takes: a kind of adjustable horse of drawing, be provided with and draw leg, body frame, pull bar, be provided with screwed hole in the middle of the body frame and run through pull bar, it is characterized in that body frame is provided with three and is the linking arm of 120 ° of angles and four linking arms that have a linking arm to form in the middle of two linking arms are wherein arranged, draw the top of leg to be provided with on the linking arm that groove is installed in body frame, groove can slide along the body frame linking arm, linking arm is provided with circular hole, be provided with spring and bearing pin in the circular hole, stop and draw leg to skid off the end of linking arm.
The utility model is simple and reasonable for structure, and is easy to manufacture, and cost is low, installation, easy to use.Owing to draw leg on linking arm, to slide, can change draw between the leg apart from the dismounting of realization to multiple size parts.
The utility model is described in detail by embodiment below in conjunction with accompanying drawing.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the vertical view of Fig. 1.
Mark among the figure: 1, draw leg, 2, body frame, 3, pull bar, 4, bearing pin, 5, spring.
The specific embodiment
Shown in Fig. 1,2: a kind of adjustable horse of drawing, be provided with and draw leg 1, body frame 2, pull bar 3, be provided with screwed hole in the middle of the body frame and run through pull bar 3, being provided with three on body frame 2 is the linking arm of 120 ° of angles and four linking arms that have a linking arm to form in the middle of two linking arms is wherein arranged, draw the top of leg 1 to be provided with on the linking arm that groove is installed in body frame, groove can slide along the body frame linking arm, and linking arm is provided with circular hole, be provided with spring 5 and bearing pin 4 in the circular hole, stop and draw leg to skid off the end of linking arm.
During use, will draw the hook on the leg to hook the parts that need dismounting, the turn pull bar moves down pull bar then, heads on and close-connected another parts of parts, and these parts are come from another isolation of components.Owing to draw leg to slide along linking arm, move and draw leg close to the pull bar direction, can dwindle the drawing diameter; Otherwise, deviate from the pull bar direction and move and draw leg, can enlarge the drawing diameter.On the linking arm end of body frame, be provided with and prevent to draw leg to move excessive and the pin 4 disengaging linking arm.The utility model is simple and reasonable for structure, installs, easy to use, because body frame 2 is provided with four linking arms, small diameter workpiece is dismantled available two and drawn leg, large-diameter workpiece to dismantle available three to draw leg.
