Description

Adjustable arm strength exerciser Technical Field The utility model relates to the technical field of body-building equipment, in particular to an adjustable arm strength device. Background The arm strength device is very common in gymnasiums as an exercise device, and China patent discloses an adjustable arm strength device in the prior art, and the application number is CN201610432935.6, the adjustable arm strength device is structurally characterized by comprising an arm strength spring and an arm strength pipe, wherein an end cover is fixed on an outer pipe orifice of the arm strength pipe, a center hole is arranged on the end cover, an expansion groove is arranged on an inner pipe orifice of the arm strength pipe, an arm strength adjusting mechanism is arranged in the arm strength pipe, the mechanism comprises an adjusting knob, a screw rod, an inner spring positioning block, an inner spring and a conical expansion joint, the screw rod is arranged in the arm strength pipe, the inner end of the screw rod is connected to the conical expansion joint, the conical expansion joint is matched with an inner pipe orifice of the arm strength pipe, the outer end of the screw rod penetrates through the center hole of the end cover to be in threaded connection with the adjusting knob, the inner spring positioning block is fixed in the arm strength pipe, and the inner spring is arranged between the inner spring positioning block and the conical expansion joint. It can be seen that the above construction is very inconvenient when assembled due to the presence of the inner spring, even if it is necessary to assemble the inner spring by means of other tools. When the arm exerciser is used for body building, the force of the arm exerciser needs to be changed according to different requirements of a user on body building force, so that the adjustable arm exerciser needs to be selected, and meanwhile, convenience and service life of structural assembly also need to be considered, so that a new technical scheme is needed. Disclosure of utility model In order to solve the technical problems and the defects in the prior art, the invention provides the adjustable arm strength device, which can adjust the handle position of the arm strength device to change the force of exercise, and simultaneously has long service life and assembly efficiency, so as to be convenient for production and use. In order to achieve the above and other related objects, the present utility model adopts the following technical scheme: The utility model provides an arm strength ware with adjustable, includes arm strength spring, arm strength pole and fixed cover, and the both ends of arm strength spring are all through fixed cover and the tip fixed connection of arm strength pole respectively, the lateral surface of arm strength pole is provided with long recess, and long recess is parallel with the axis of arm strength pole, has cup jointed lock sleeve and handle on the arm strength pole, the inner of handle is equipped with the screw rod, and the outer end of arm strength pole is provided with the screw hole with the screw rod adaptation, and handle and arm strength pole rotatory movable fit and screw rod stretch into in the arm strength pole, and the inner of handle is equipped with the lockhole, and the terminal surface of lock sleeve is provided with the latch piece with the adaptation of lockhole grafting, is equipped with the sand grip with the adaptation of sliding of long recess on the interior anchor ring of lock sleeve.
