Abstract
The utility model belongs to a repair tool, which is a changeable type pulling force device, comprising a main frame, pull claws, a screw rod, a core clamper, etc. The screw rod and the core clamper of the changeable type pulling force device are separated. The core clamper can be randomly taken off or connected. Due to the fact that the core clamper can be long or short, the core clamper is connected with the screw rod by adopting the cuttage grafting form. According to different pulled work pieces, the screw rod can be caused to be optionally lengthened or shortened, which causes the pulling-force device to be suitable for the repair and the use of various work pieces, and moreover, the changeable type pulling force device has simple operation, convenient operation, good concentricity, and can prevent the phenomenon that the work pieces are pulled to be damaged, and can accelerate the repair velocity.
Description
The utility model belongs to a kind of maintenance tool, a kind of relay-type chest expander.
Known chest expander, its leading screw and top one constitute, so, the length of leading screw is fixed, and when pulling out workpiece, the situation that leading screw can not reach should length usually occurs, workpiece can not be pulled out, and at this moment, the operator has to repeatedly insert nut, iron staff, iron block etc., to add the length of long lead screw, until pulling out workpiece, existing chest expander is troublesome poeration not only, delay work and mistake, and do not guarantee concentricity, and make the pulling claw unbalance stress, draw bad workpiece easily.
The purpose of this utility model provides a kind of relay-type chest expander that can change leading screw length.
Technical solution of the present utility model is: with leading screw and top split, an end setting of leading screw can arbitrarily take off or connect top.
Because top changeable, the user can be according to the difference of workpiece, connects different top of length arbitrarily, makes chest expander be adapted to the use of various workpiece.The utility model is easy to operate, and maintenance speed is fast, can prevent to be drawn the damage of workpiece, has certain economic benefits and practical value.
Narrate implementation method of the present utility model below in conjunction with accompanying drawing.
Fig. 1 implements a kind of structural representation of the present utility model.
Fig. 2 is the structural representation of leading screw one end of amplification.
Fig. 3 is the top structural representation that amplifies.
Fig. 4 is the A view of Fig. 2.
Fig. 5 is the B view of Fig. 3.
Fig. 6 is a kind of concrete use figure of the utility model.
Among the figure, 1, body frame; 2, pulling claw; 3, leading screw; 4, top; 5, cantilever; 6, adjusting screw; 7, linking arm; 8, movable axostylus axostyle; 9, roll adjustment screw; 10, locking ball; 11, spring; 12, boss; 13, axostylus axostyle; 14, recess; 15, groove; 16, axis hole; 17, workpiece; 18, axle.
Referring to Fig. 1, the utility model by body frame 1., pulling claw 2., leading screw 3., top 4. the grade form, its leading screw 3. with top 4. be split, a leading screw end setting 3. can arbitrarily take off or connect 4. top.Because top 4. changeable, the user can be according to the difference of workpiece, connects different top of length arbitrarily.Make leading screw 3. elongated or shorten, make chest expander can pull out various workpiece.Leading screw 3. with the top grafting form (seeing Fig. 2, Fig. 3 for details) that preferably adopts, leading screw link 3. is provided with groove (15), the center is provided with axis hole (16), top link 4. is provided with boss (12), the center is provided with axostylus axostyle (13), and the two just in time matches, and can directly insert to get final product, this structure stress situation is better, and can guarantee concentricity preferably.In order to prevent top skidding off 4., one location steel ball is set 10. in the leading screw axis hole (16) 3., the two just in time matches on the correspondingly top axostylus axostyle (13) 4. a recess (14) to be set, locking ball is 10. under the effect of spring (11), 4. played certain fixation to top, toply generally speaking 4. can not skid off automatically, more convenient to use.
The utility model leading screw is not limited only to the grafting form with top being connected, and also can adopt silking to connect or other other form connection.
Claims (3)
1, a kind of relay-type chest expander, by body frame 1., pulling claw 2., leading screw 3., top 4. the grade form, it is characterized in that: described leading screw 3. with top 4. be split.
2, relay-type chest expander as claimed in claim 1 is characterized in that: leading screw link 3. is provided with groove (15), and the center is provided with axis hole (16), and top link 4. is provided with boss (12), and the center is provided with axostylus axostyle (13), and the two just in time matches.
3, relay-type chest expander as claimed in claim 2 is characterized in that: locking ball is set 10. in the leading screw axis hole (16) 3., on the top axostylus axostyle (12) 4. a recess (14) is set, the two just in time matches.
