Abstract
The utility model relates to a hand-operated tool for dismantling machinery parts, in particular to a puller capable of adjusting, which comprises pulling legs, a main frame and a pulling rod, wherein a threaded hole is arranged in the middle of the main frame so as to enable the pulling rod to penetrate through, and four claw-shaped connecting arms are arranged on the main frame. The puller is characterized in that a through groove is arranged on each connecting arm, pin shafts are arranged at two ends of the top parts of the pulling legs, the upper parts of the pulling legs are provided with through holes, springs are internally arranged in the middle of the through holes, steel balls are arranged at two ends of springs, the pulling legs are arranged in the through grooves of the connecting arms, and the steel balls at the two ends of the springs lean against the inner walls of the through grooves of the connecting arms in a pressing manner. The puller is simple and reasonable in structure, easy to manufacture, low in cost, and convenient to install and use, and as the pulling legs can slide on the connecting arms, the puller can realize the dismantling of parts with various sizes, and change the direction of claw parts of the pulling legs, thus meeting the use requirements of outward pulling and inward pulling-out.
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, that draws horse draws leg normally fixed, the horse of drawing of general certain model is merely able to dismantle the machine components of certain size size; The diameter of drawing workpiece receives the restriction of drawing the horse specification; Commonly draw horse to have only a kind of function, draw outward or in pull out, its versatility is poor.
Summary of the invention
The purpose of the utility model is in order to solve the deficiency of above-mentioned technology, to provide a kind of simple in structure, and cost is low, be prone to make, and is flexible and convenient to use, can adjust the opening amount, can realize drawing outward and in pull out adjustablely draw horse.
The technical scheme that the utility model is taked: 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; Body frame is provided with four linking arms that are claw type, it is characterized in that linking arm is provided with groove, draws two ends, leg top to be provided with bearing pin; Draw leg top to be provided with through hole, the centre in through hole is equipped with spring, at the two ends of spring steel ball is installed; Draw leg to be installed in the groove of linking arm, the both ends of the spring steel ball is pressed against on the inwall of linking arm groove.
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 realize dismounting to multiple size parts; Change and to draw leg claw direction, can realize drawing outward and in the instructions for use of pulling out.
The utility model is described in detail through embodiment below in conjunction with accompanying drawing.
Description of drawings
Fig. 1 is the structural representation of the 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, big steel ball, 5, steel ball, 6, spring.
The specific embodiment
By Fig. 1, shown in Figure 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 2 and run through pull bar 3; Body frame 2 is provided with four linking arms that are claw type, on linking arm, is provided with groove, draws two ends, leg 1 top to be provided with bearing pin; Draw leg 1 top to be provided with through hole, the centre in through hole is equipped with spring 6, at the two ends of spring steel ball 5 is installed; Draw leg 1 to be installed in the groove of linking arm, the tension force of spring is pressed against the two ends steel ball on the inwall of linking arm groove.
During use, the hook that draws leg 1 bottom is hooked the parts that need dismounting, the pull bar 3 in the middle of the turn body frame 2 moves down pull bar 3, and big steel ball 4 heads on and close-connected another parts of parts, and these parts are separated from another parts.Owing to draw leg in the groove of linking arm, to slide, move draw leg to the pull bar direction near, can dwindle the drawing diameter; Otherwise, deviate from the pull bar direction and move and draw leg, can enlarge the drawing diameter.When drawing leg 1 to take out in the groove of body frame 2 linking arms and inserting, change the hook direction of drawing leg 1 bottom, just can realize the transformation that inside and outside pawl draws horse, thus can satisfy that different occasions are externally drawn and in the instructions for use of pulling out.
