The specific embodiment
As shown in Figure 1, the pin provision for disengagement, be used to dismantle the pin that is provided with screwed hole, comprise the dismounting double-screw bolt 34 that is connected with described pin thread hole, one end of described dismounting double-screw bolt 34 is fixedly connected with slide bar 2, slip cap is connected to slide block 1 on the described slide bar 2, and described slide bar 2 is provided with slide block away from an end of described pin and impacts portion 21.
Wherein, be provided with fast replacing device between described dismounting double-screw bolt 34 and the described slide bar 2.Described fast replacing device in the present embodiment comprises the dismounting double-screw bolt handle 33 of fixedlying connected with described dismounting double-screw bolt 34, is threaded between described dismounting double-screw bolt handle 33 and the described slide bar 2.Described being threaded comprises the connection double-screw bolt 23 that is arranged on the described slide bar 2, is arranged on the screwed hole 31 on the described dismounting double-screw bolt handle 33, and described connection double-screw bolt 23 and described screwed hole 31 cooperate.Certainly, common engineers and technicians as this area, described being threaded also can be adopted following version: described being threaded comprises the connection double-screw bolt 23 that is arranged on the double-screw bolt handle 33, is arranged on the screwed hole on the described slide bar 2, and described connection double-screw bolt 23 and described screwed hole 31 cooperate.
As Fig. 2, shown in Figure 3, dismantle the replacing and the dismounting of double-screw bolt 34 for convenience, the external peripheral surface of described dismounting double-screw bolt handle 33 is provided with at least one pair of clamping plane 32 that makes things convenient for clamping, also is provided with the clamping plane 22 that at least one pair of makes things convenient for clamping on the external peripheral surface of described slide bar 2.
For ease of operation, the external peripheral surface of described slide block 1 is be convenient to grip streamlined.
During work, dismounting double-screw bolt 34 is screwed in the screwed hole that needs the dismounting pin, slide up and down slide block 1, slide block 1 stressed quick impact slide block impacts portion 21, slide block impacts portion 21 impulsive force is passed to slide bar 2, slide bar 2 passes to described dismounting double-screw bolt 34 with impulsive force, and described dismounting double-screw bolt 34 drives pin by being threaded and moves upward, and reaches the purpose that pin is progressively separated.Different pins only need be changed different dismounting double-screw bolts 34 and get final product, and the utility model can also be dismantled the small parts with threaded hole of similar pin.
Should be understood that these embodiment only to be used to the utility model is described and be not used in and limit protection domain of the present utility model.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
